A Look At The Final Fantasy XI Job The Black Mage

2008-03-04T17:40:00.000-08:00

Black Mages are the specialists of the Black Magic and all other spells that are used for dealing damage. Black Mages are said to be the damage artist, though this is a thought which should be carefully understood. Black Mages have the broadest sorts of damaging spells available to them, some of which can hit for astonishing sums of damage. However, not all players see Black Mages as being the most overall damaging job, despite their enormous powers. This is because in longer fights, the Black Mage can run out of MP (Magic Points), entailing that eventually other jobs can out damage the Black Mage. With this fat already known, a good Black Mage would know how to quickly deal enough damage to finish the fight.

The Black Mage is the ultimate offensive spell caster bringing death and devastation to the battle field from a distance. They are not so good at taking damage or physical attacks but their strong spells make up for that.

In some ways, Black Mages are best compared to Monks. Both jobs are good at dealing large amounts of quick damage, but do not do as well absorbing damage themselves.

Black Mage magic is mainly damaging magic, with some disabling spells as well. Black Mages can not cast healing magic. Note that all mages need to learn a spell before they can cast it. Learning a spell involves buying the spell scrolls (similar to how warriors must buy weapons) and then learning (using) it to put it into their spell book.

As with the White Mage, the Taru Taru is the best race for the Black Mage because of their high MP. Casting a lot of spells will take up MP fast so you will need a lot to make sure you don't run out in the middle of battle.

The Black Mage has the active abilities of Magicfont which gives the mage unlimited mana for 30 seconds and Elemental Seal which increases the accuracy of the next spell cast. Take note that Magicfont can only be used every 2 hours so it is best used when in great need of mana only.

The passive abilities of the Black Mage consist of Magic Attack Up at levels 10, 30 and 50 which increase the magic attack skill. Clear Mind at level 15 which inreases the mana regeneration rate of the mage. Conserve MP at level 20 which decreases the amount of mana used by spells. HP Boost at level 55 which increases the maximum HP of your character and Martial Arts at level 60 which increases the Black Mage's hand to hand combat abilities.

The Black Mage spells are all different elementals like Earth, Water, Fire, Ice, Wind, Thunder and Darkness. Each type of element does different amounts of damage depending on the enemy, so it is best to know the weakness of the enemy before casting. Some spells may even heal an enemy if that is their element.

How to Manage Your Mood with Food: A Meal by Meal Guide

2008-03-02T19:04:00.000-08:00

Here is a meal by meal guide to eating for energy and managing your mood with food.

Breakfast

Eating a good breakfast boosts your concentration and revs your energy, particularly in the morning when you may need it most.

You can help keep your blood sugar on an even keel with complex carbohydrates. Avoid refined carbohydrates, such as white bread and white sugar. These have a high glycemic index, which can cause spikes and dips in your blood sugar levels.

The right complex carbohydrates provide your brain and muscles with the steady flow of the energy they need. Grains are great sources of B vitamins, which aid in the metabolic production of energy. Natural whole grain breads and cereals are good carbohydrate choices for breakfast.

For the best breakfast, add a lowfat protein, such as yogurt, cottage cheese, or skim milk, and watch your fat intake as well as your meat consumption (since meat takes more energy to digest).

Mid morning snack

Turns out, snacking may not be such a bad idea. Eating every few hours helps your body use nutrients more efficiently. It stimulates your metabolism, keeps your blood sugar levels steady, reduces stress on your digestive system, and decreases hunger, which means you will be less likely to overeat when mealtime finally rolls around.

If you are craving carbs, which many of us do at this time of day, choose whole grain bread, cereal, or fruit.

Fruits and vegetables deliver a lowfat, high fiber alternative to the vending machine choices. Raw carrots and sugar snap peas, for example, provide a crisp, satisfying crunch and will not zap your energy. Challenge yourself to eat at least five servings of fruits and vegetables each day.

For maximum energy throughout the day, avoid foods that are laden with simple sugars, such as cookies, pastries, candy bars, and sodas, which can bring on erratic blood sugar levels.

Instead, try some lean protein (lowfat yogurt, cottage cheese or lean meat) to help tide you over until lunch.

Lunch

At midday, go light. Because a hefty helping of carbohydrates can increase the amount of seratonin in the brain and cause that sleepy feeling, focus on lowfat protein.

Protein can actually raise energy levels by increasing brain chemicals called catecholamines. Eat a lunch of lowfat cheese, fish, lean meat, poultry, or tofu.

Mid afternoon snack

Choose something that will keep you satisfied until dinner. A little bit of fat is fine. It gives those carbohydrates and proteins some staying power. Try a bit of all natural peanut butter and a few crackers, for example.

Before your workout

Carbohydrates are fastest to digest and pack quick energy. Add protein for staying power, but stay away from fats. They can make you cramp.

Dinner

The agenda for the evening can dictate what you will eat for dinner. Need to stay on overdrive for a couple of hours? Choose lowfat proteins. If you are in relax mode, indulge a little.

Whatever is on the menu, remember the Pie Test. Envision your plate as a pie. Seventy five percent of the pie should be filled with fruits, vegetables, and grains and 25 percent with other foods, such as diary products and meat.

Before bed

Before turning in, a carbohydrate rich snack can supply seratonin to help you fall asleep. But go easy. Too much food can reduce the quality of your sleep.

Things About Foreclosure That All Home Owners Should Know About

2008-02-29T20:34:00.000-08:00

Foreclosure means basically that you were unable to pay your monthly mortgage payments so the mortgage company decides to repossess your home. It is just like with a vehicle or anything else where you are bound by some form of a contract or agreement, if you do not hold up on your part of the deal somebody will come and take your car from you or your furniture. Most people have probably experienced a time in their life where they found they were going to have to put off paying one or more payments within the month because of one thing or another coming up unexpectedly. If you ever feel like foreclosure could be just right around the corner for you, then you should most definitely make all attempts to contact your mortgage company and let them know what is going on with you and that there is a possibility that your mortgage payment will not be made on time.

Usually if you are honest with them and not trying to avoid them, they will generally allow you the opportunity to explain your situation upon deciding what needs to be done in order to get your account current. Things that are unfortunate do happen sometimes throughout life and it is normally whenever we least expect it, but as I mentioned, if you do suspect that something could prevent you from getting your payments in on time, be sure that you take the time out to call your mortgage company, just to let them know what is happening with you and when they could possibly expect your payment. Foreclosure is a very terrifying word for many individuals and many times the reason that it is so terrifying is because most people are just simply not aware of the fact that most of the times, something can be done to prevent this from happening to you. Losing your home that you have called home for so long now is something very tragic and can cause many people to feel as though their lives are literally falling to pieces.

Do not let this put you into any sort of deep slum because no matter what happens, you are strong enough to get through almost anything that life has in store for you, including this. There are many things that you can do to try and fight this type of action against you and typically if you atleast give it a real good try, things will just seem to work out for you. Not always but most of the time it is possible for anybody to tell their side of the story, no matter what it may be, and have the mortgage company change their minds about serving you with any foreclosure notice. If you do lose your home to foreclosure, it is very unfortunate and will definitely have a negative affect on your credit rating for many years to come. You will have to put it in your head that you are tough enough to rebuild or move on and get your finances back in order, the way that they should be, so that you are never faced with having to deal with this type of situation again.

Little England is no little at all.

2008-02-28T02:33:00.000-08:00

Barbados, also known as Little England is in fact no "little" at all.

It is perceived as virtually far because its not very easy to reach and is detached from the rest of its neighboring islands, yet it is one of most visited tourist attractions in the Caribbean. It is a hideaway to most travelers because its hard to get to but then harder to leave, as one travel site described it.

Barbados is a small island located at the southern Caribbean region and has a growing population of 280,000. It is part of the Lesser Antilles island chain that runs with Bahamas and Greater Antilles to form the West Indies.

With its subtropical climate, the Barbados Island forests and mountains have been naturally nourished, which makes it a great site for nature tripping, hiking, jogging and cycling. Even golfers, professional and amateurs, have found a haven in this paradise. Yearly, several sporting events are held in Barbados, including events for boat and parasailing.

As their habitat was protected, so were Barbados wildlife and marine life. Animal lovers will be happy to know that there are great destinations in Barbados where you can actually interact with the animals. Most recommended in Barbados is the Wildlife Reserve where a whole day can be spent just looking at all the beautiful creatures. For aquatic life, there are several options, too. You can visit Ocean Park where big and small aquariums display the most colorful and unique marine living creatures, where children can see them up close. Another way to do it requires further physical challenge, which is to go snorkeling or diving. Some can book for one of the packages in a cruise company where visitors can actually swim with the turtles.

There are many a great beaches and parks in Barbados for all water sports lovers out there. The sandy beaches send tingles and excitement beneath the feet of children and carpet for a couple. Rich in corals and undisturbed marine life, beaches in Barbados are also great for scuba diving. You can check out the Grand Barbados Beach Resort, Almond Resorts Barbados and a lot, lot more.

Other travelers love Barbados for the cultural heritage it has retained intact. Houses, churches, museums and other structures are living proofs of how the Barbados was during the British arrival in the 1620s. Even tools Bajans used hundreds of years back have still stood the hands of time. See the displays of silverwares, prints, antiques and tools at Barbados Museum and Sunbury Plantation House. Also see the picturesque churches like St. Philips Parish and houses, a good example of which is George Washingtons temporary house when he went to Barbados for his only international trip.

Celebrating their culture, Barbadians are also rich in festivities. The longest taking a whole month of preparation and the event itself is the Crop Over. Other festivities include the Oistins Fish Festival and Holetown Festival.

Barbados or Little England is no "little" at all in its historical, ecological and grandeur sense, because it is one great and wondrous place just hidden away in a small island.

How To Negotiate Salary

2008-02-26T21:33:00.000-08:00

1. Don't negotiate salary at interview

Whilst both you and a prospective employer might be keen to agree salary at interview, don't bring it up. Usually before you apply for any job there will be a guide to what salary is on offer. If you're asked what salary is on offer simply state "The practical details can be worked out at a later date"

Not discussing salary at interview will improve their respect for you as it gives the impression that salary is less important than the role itself, even if it isn't. You interviewers will be left with a positive impression of you and are more likely to offer a good salary because of it.

2. Always turn down the first salary offer

This needs to be done diplomatically. When they call you and make a salary offer, thank them for the call and stress how excited you are by the prospect of working for them, but explain that you need to think it over. Call them back the following morning and explain that whilst you like the job and the organisation the salary offered was a little lower than expected. Tell them that if they make a final improved offer that you will take the job.

This works like a charm and I've seen people get up to $4,000 more on their basic salary for politely turning down the first salary offer made to them.

3. Speak to the decision maker

Most large companies have Human Resource departments that deal with recruitment and make job offers. They are usually rigid salary bands that they will stick to when making you an offer, but these people have little input on organisational affairs and don't know your true potential value to the organisation.

If you get an offer you are disappointed with and the HR department refuses to increase it then go to the real decision maker, the hiring manager. Usually the hiring manager, whom you will inevitably work for, will have interviewed you along side a member of HR staff and it is they who have the real power. Call the switchboard and ask to speak to the hiring manager who interviewed you. Be really polite and explain that the purpose of the call was to thank them for their time at interview and that it is a shame that the offer made by the HR department wasn't enough for you to take the job, as you were looking forward to joining the company. Nine times out of ten you'll receive a call from the Human Resources department within 48 hours, who having been contacted by the hiring manager, want to make a revised offer that is much closer to what you were expecting.

4. Provide Evidence of Market Rates

Usually employers make a salary offer based on what they think you are worth to their organisation. If you want to get an improved salary you need to demonstrate that what you are asking for is not unreasonable and is the going market rate. Visit an online job search site like www.monster.com and check out what other people doing your job are being paid by other companies. Print off this information and take it with you to salary negotiations to evidence your claims.

5. Read Recruitment Magazines in the office

If you are already in employment and are approaching a salary renegotiation period start taking recruitment magazines into work with you and reading them during your lunch break in the office. Ideally circle a few jobs similar to your own and leave that page open on your desk. I guarantee that word will soon spread that you are keeping a look out for a new job. When it comes to your turn to negotiate salary you will have put yourself in a strong position with management to get an improved basic wage.

Criteria of Choosing an Ideal Web Hosting Company

2008-01-02T23:03:00.000-08:00

Before we talk about what it takes to be a cheap and good quality web host, lets get to the fundamental first. What is a Web Host?
A web host is a service provider that places your web site on a computer which is connected to the internet. The term for this computer is called a server.

A web hosting provider will typically have a fast connection to the Internet and they may host thousands of web sites on many servers. The web host essentially rents out space to you so that you can get your website up on the world wide web.

With a well-managed web host, you can free yourself from worrying the up-keep of complicated server technology and proper technical maintenance. Thats the whole purpose of the web hosting companies. You should leave the technical work to web hosting professional while you focus on your own internet business.

Lets begin...

Feature Offered
The features that web hosting companies are offering are getting quite standard nowadays.

The followings are some of the common features you'll see in most web hosting plans: Control Panel
Control Panel is an interface where you can access your site on the web server, allowing you to set-up and subsequently update and customize your web site. Though cPanel is by far the most popular control panel, some hosting providers customize their own so that they can up-grade and expand it at will. Diskspace
A vast majority of sites that don't have tons of graphics, sound and video clips or downloadable files easily fit in 50 MB of disk space. You should always leave yourself some room for growth or check if the host has a bigger plan in case you need to upgrade. Bandwidth
Bandwidth is the amount of data transmitted or received through a unit of time. In web hosting, bandwidth is consumed when visitors make requests for files on your web site and download them to their personal computers. Email Account
With POP3 email accounts you can check email from Outlook, Netscape Mail, Eudora or any other Email software. Scripting language
As all our top 10 listings are using Unix and Linux platform, php, perl and CGI are the languages we are talking about here. It is best to choose a host that supports the latest version to maximize the latest web technologies for the fee that you pay. Database
If your web site is going to store a lot of data that should be dynamically accessible (like user accounts, stock prices, maps, Interactive news, message boards and forum etc.), you'll need to look for an account that offers a database. MySQL is a powerful and most popular database program that runs on the Linux operation system. It is able to handle million of entries all at once. Its flexibility and speed allow you to also store logs and pictures. MySQL is designed to scale well under heavy traffic conditions and is ideal for database-intensive or e-commerce-enabled Web sites. Customer Service/Support
No matter if you are an expert or a novice in web hosting, you need a web host with good customer support system. What is the criteria of an excellent customer support? Let us explain. How big is the knowledge base?
This is particularly important for those who want to search for quick answer without seeking direct assistance from customer support staff. Due to the huge database, normally its searchable. Some web hosting providers will even make your life easier by making a video tutorial guiding you step by step in setting up your new account. Very useful for beginner. Responsive customer service staff.
If you are too lazy to find the answer out of a big pool of database, get the direct answer from someone who knows it. Direct customer support comes in a few forms.
a. Email support

b. Phone support: Normally, sales and technical support uses separate phone line. A good phone support staff knows what your problem is and answers with relevance.

c.Web Host like Lunarpages and Globat even have live chat support. However, its not how many support channels that are available but how responsive it is of the staff. You can find out the hosting reviews and ratings of each of our Top 10 Cheap Web Host.

Price to Disk Space / Price to Bandwidth Ratio
Are you paying too much for your Web Hosting Plan?
Having done the research on hundreds of web hosting companies, in general, weve come to this conclusion: the more disk space and bandwidth you are getting, the more expensive is the monthly price.

To help you understand which price is competitive enough for you to take up the offer, we have categorized 5 different price range. For each price range, a score of maximum of 10 is assigned. To understand the concept behind this, please refer to the details here.

Popularity
A web host might have the best feature offered, unbeatable customer support and reliability in place but without an effective marketing plan, it will go bust too. Lets face it. If a web hosting provider does not have sufficient members and steady growth of new members, its very difficult to survive in this highly competitive industry.

We judge the popularity of a particular web hosting provider by looking at the number of awards won, the reviews of other websites and the Alexa traffic ranking.

All the hosting providers listed on our Top 10 Cheap Web Hosting Directory are among the top 40,000 most visited websites in the world.

Reliability, Speed and Uptime Guarantee
Nothing can hurt you more than this: your visitors come to your web site only to find that its not accessible. You lose credibility and possibly even a sale. If your web host does not guarantee at least a 99% uptime, leave the web host now!

To ensure maximum uptime, installation of redundant back-up systems is essential. Each web host has their own management systems to minimize downtime. "Redundant" means that if any of the Internet connections get interrupted, the alternate Internet connection will take over.

We use Alertra software to monitor the uptime of each of our top 10 web hosts.

As for speed, even though routing, web server set up and local area networks play a part in determining the speed of a site, the main concern of how fast your site is depends very much on the types of network connections.

Many hosting providers still connect to the Internet through T1, or T3 connections. This is not the case for our top 10 hosts- they are using OC (Optical Carrier) lines.

A T1 line will offer data transfer rate of 1.5 Mbps (megabits per second), while a T3 line can supply data transfer rates of 43Mbps. OC-1 refers to a circuit that transmits 51.85Mbps. Higher levels are multiples of that speed. Ultra-High Speed OC3 and OC12 lines offers 155Mbps and 622Mbps respectively. Some hosting providers have connections to major internet backbones at the speed of OC48 (2488Mbps) and OC96 (4976Mbps).

Mp3 Player Buying Advice

2008-01-01T23:54:00.000-08:00

Music is one of the best sources of entertainment. It is music that can work wonders at times. Even medical science believes in the miracle of music, and incidents are not very rare where the so-called `music therapy` has cured diseases that medical therapy has failed to do. Hence, the popular propensity towards music has improved considerably.

However, this interest for music has increased in an unprecedented fashion ever since the market was flooded with gadgets like MP3/MP4 players and iPods. These gadgets are widely popular due to their portability. But, portability is not the only deciding factor that you should consider while buying an MP3 player. There are several other elements that have to be taken into consideration before buying an MP3 player.

1. What do you want an MP3 player for? Choose according to your needs, listening to music in your bedroom is different from doing so in the kitchen or living room. In such cases, go for an MP3 player with an optional stereo dock. If you want to listen to tunes during work-out, then opting for a flash-based MP3 player is a wonderful idea.

2. It is always a good idea to spend some time with the MP3 player in person instead of assuming that it would be as good as it is shown in the ads. Incase, you want to buy it online, visit an electronics store to physically handle it and see if it is suitable in all circumstances of your day-to-day activities.

3. Always make a research before by an MP3 player. You can read magazines such as CE Lifestyles or take the opinions of your friends, colleagues, acquaintances and relatives who may have used it before. It will save you a great deal of time and after-buy regret.

Whats to see in Afghanistan

2007-12-29T00:03:00.000-08:00

Afghanistan is a country in Central Asia that has borders with Iran, Pakistan, Kyrgyzstan, Uzbekistan, and Tajikistan. Also, the country has a very short border with China that has resulted from quite a strange deal between the British and the Russian Empires in the 19th century. Throughout the 1970s Afghanistan used to be quite a popular destination as the hippies would travel to India more than ever. Kabul, the Afghan capital city used to be a very hip place to hang out and party back in that period. Things have dramatically changed for the Afghan tourist since then.

Everything started in 1979 when the Soviet Union invaded and occupied the country. Ten years later the Soviet army was forced to leave Afghanistan as the anti-communist Mujahidin forces, which were supplied and trained by the United States, Saudi Arabia, Pakistan and others. The Islamic Taliban movement has taken over most of the country and there is continuous violence among the various Mujahidin factions. Also, besides all the political problems the Afghan population is also confronting with continuous civil strife, enormous poverty, poor infrastructure and widespread live mines.

All these make Afghanistan an unpopular tourist destination and only the brave and the adventurous tourists venture outside Kabul or the main cities. On the other hand, the Afghan population is not particularly fond of foreigners, thus tourists are not very much welcome inside the country. Most tourists who choose to visit Afghanistan are attracted towards crossing the Khyber Pass from Pakistan and go on to Jalalabad. It is important to note that the Jalalabad city is quite safe, but the border is a little more dangerous as it is Taliban country. Once here you can go on the road that leads to Kabul, but you have to keep in mind that it is quite dangerous to venture by yourself and that attacks on foreigners have very much increased since 2003. You can however choose to travel escorted by armed Afghan people who offer their services for protection. A safe way to visit the country is to fly to Kabul and visit all the other cities by air. It is not recommended to wander around the country and the cities in the South and East should be avoided. However, cities like Kabul, Mazar-i-Sharif, Heart and a few others in the North-West area are considered to be relatively safe for visitors. Please take into consideration the fact that many governments declared that traveling to Afghanistan is not safe, although it is an enchanting country with exciting culture and history.

Kabul is the capital city and is located in the center of the country. The city is considered to be Afghanistans major tourist attraction due to its day and night life, culture and sites. It is definitely the best choice to explore as, although it is considered a dangerous city in a dangerous country, the safety rates are quite high in comparison with the rest of the country. Some of the biggest attractions here is the Kabul Museum and the famous Garden of Babur. Also, the Valley of Paghman is a very beautiful place to visit, but beware that there are no busses to take you there.
Herat is another tourist attraction in Afghanistan and it is very close to the Iranian border, being the second biggest city in the country. It has always been considered a relatively safe place for travelers. Even though the Irano-Afghan relations have dropped to an all-time you can still cross the border from Iran. You will need valid passports and visas, though a visit to the State of Israel will prevent you from entering Iran. The tourist attractions in Herat are the huge defensive walls and earthworks that have been preserved since ancient times. The Friday Mosque is dating since the 10th century BC and the Gazergah monastery and mausoleum is about one thousand years old. One very interesting thing about Herat is the fact that it hosts the first women only university world wide. Today, Herat is the most important Afghan industrial center and it is also considered to be the safest city in the country.
Mazar-i-Sharif is another major tourist attraction in Afghanistan. The translation of the citys name is something like Tomb of the Chosen One and it comes from the fact that the city is hosting the tomb of Hazrat Ali, a very close relative of the prophet Mohammad. The Blue Mosque is also another tourist attraction in this city.

Bank deposit and lending rates again stressed Yantai people queuing up to the early morning of

2007-12-22T06:51:00.000-08:00

Re-adjustment of the central bank's benchmark interest rates for deposits and loans in RMB, demand deposits down for the first time in five years, Hor Namhong Street in the city, and other cities in the north of the city roads, a number of banks had to be from a long row team.

After one year, will expire 10,000 yuan to keep the three-year, and so, after three years, all holders of certificates of deposit for the three-year period, the age of maturity is different, followed by a difference of one year.

Things you should know before buying digital camera

2007-12-09T23:29:00.001-08:00

If you are looking to buy a digital camera, you should properly educate yourself about all the different aspects of digital cameras. There are many types of digital cameras out there all with different features, so you should first ask yourself a few questions before actually spending several hundred dollars on your big purchase.

1. What exactly are you going to be using the camera for?

2. Will it be used as part of your job or will you use it for recreational purposes?

3. Should you buy a mini digital camera or should you look for a standard size digital camera?

4. How much money are you willing to spend and what is your budget for your digital camera expenses?

Remember, the camera itself is just one part of the cost; you still need to pay for batteries, computer cables, and memory and media types for storing your pictures and video.

Some other things you should keep in mind when trying to select a suitable digital camera are the weight of the camera and the look and feel of the digital camera. If you need to take the digital camera with you during your daily routine or job, you should make sure that it will not get in the way of whatever it is that you need to do. Another important aspect of digital cameras that you should be aware of is the zoom function.

There are two basic types of zoom, optical zoom and digital zoom. Optical zoom is the type of zoom where you press a button and the lens physically moves around in order to zoom in or out. This is the zoom method that you are probably the most familiar with. The other type of zoom is known as digital zoom.

Digital zoom is a new method of zoom that has been introduced with the invention of digital cameras and does not rely on any moving parts. It basically crops the photo you take and then enlarges it, which in effect creates a type of optical zoom effect. Generally speaking, you should try to use optical zoom over digital zoom, since digital zoom reduces picture quality by a great deal in most cases.

If the reason that you want to buy a digital camera is for recreational purposes only, you should consider the option of buying a mini digital camera. Generally speaking, mini digital cameras are not as powerful as your standard size cameras, but they have several advantages. Obviously, they are portable and very convenient to bring along with you on your travels. Most mini digital cameras will fit in your pocket without a problem, whereas standard size digital cameras can be quite bulky and awkward to carry around at times.

Another benefit of having a mini digital camera is the fact that they are great to show off to your friends and family. They make great conversation starters and if anyone sees you taking a picture with a tiny digital camera, odds are that they will stop to chat with you a bit about the price and specifications of your camera. Finally, mini digital camera accessories are a bit cheaper than standard sized accessories so you can expect so save a bit of money when buying your accessories.

Vital Tips for Document Scanning Software Buyers

2007-12-09T23:29:00.000-08:00

The requirement to save paper and control the management of workflow documents and images continues to be driven by two main methods: managing costs through efficiency and managing environmental concerns through technology. The need is therefore continuous and ongoing, to ensure the correct acquisition of document scanning software with functions which fit the purpose. This summary highlights some important considerations when buying such software.

Categories of Document Scanning Software

Document scanning solutions fall in to one or more of the following categories by function. These are

1) Ad-hoc scanning of individual documents into computer files

2) Desktop batch scanning of documents to network files or to a document management system

3) High-volume, multi-user scanning of documents to document management system

4) Automated indexing of documents from multifunctional printers, network scanners or distributed capture

5) Applications which automate data entry tasks using handprint recognition and dynamic Optical Character Recognition (OCR) to capture data from images

Which Scanning Software Features?

The key to the best practice and most efficient document scanning is to specify as many automation features as possible to eliminate manual indexing and at the same time make all documents fully searchable.

An excellent way to achieve this is with barcodes. Barcodes can be recognised with a very high rate of speed and accuracy and a minimal possibility of false positives.

Another way is via Optical Character Recognition (OCR) which can be used to read indexes from machine print on scanned images. It's not as quick as barcodes, and the recognition rate is not as high, but it has the advantage with documents that were not designed with scanning in mind.

An efficient user-friendly interface design will also save you time in setting up, training staff and supporting the document scanning application. Clearly, staff will respond better to any work pattern changes with a more efficient interface for their daily work. For this reason the user experience must be a paramount consideration..

Other Key Scanning Software Features

Features and areas requiring attention and comparison between software brands are:

License Type: Is the license server or workstation based? Do any monthly page limits apply?

Platforms: Presently, almost all batch scanning system is limited to the Windows user environment.

Export Capabilities: How is index data exported? Keywords can be used to organize images into logical folders and filenames on a network, for example. Alternatively it can be exported to delimited text files for import into other software systems. Or again, it can be added directly to an ODBC or OleDB database.

Scanner Support: Almost all scanners support TWAIN drivers. These days, ISIS drivers are also supplied with most document scanners available. Real-time image enhancement on scanned images is supplied by Kofax - native support for Adrenaline image processing boards.

Document Scanning and Management Systems: A Review

2007-12-09T23:28:00.000-08:00

Document management systems let businesses store and search digital documents, whether they are scanned images or MS Office documents, PDF files or CAD drawings. Some have a web-based interface to let you view files online, while others have an installed client application for better speed and functionality. All of these solutions require a central database and storage server to hold the files and index information used for searching.

These document management systems require a few days in planning, installation, configuring and training. This is definitely time well spent, ensuring that a correct and optimal implementation at the outset will revolutionise the way in which any company works with its records.

This review highlights a range of proprietary document scanning and document management software, with key functions which they offer.

Systems to Store, Search and View Documents

PaperVision by DigiTech and CompuThink's ViewWise both provide fully featured, HIPAA-compliant (Health Insurance Portability and Accountability Act) document management systems. Both of these systems can grow with company needs, and are affordable enough for small businesses yet powerful enough for large corporations too. Each offers some benefits that the other does not.

To take PaperVision first: this software suite includes a customisable application for searching and viewing, as well as a web interface. PaperVision also has workflow and report management modules which boost any return on investment by allowing the automation of document processes and eliminating pre-printed forms.

A "lite" version called PaperVision XPress offers a similar search interface as PaperVision Enterprise, but comes in at a lower cost, without the extra scalability, security and options.

The other fully featured in-house system featured here is ViewWise. This system is unique in that it is Java-based and can run on Windows/SQL Server as well as Novell, UNIX and Linux operating systems and Oracle database servers. ViewWise also has several key differences in the layout of its user-interface that many users prefer. This includes a folder view for browsing documents.

For a simple, low cost scanning front end for these document storage and retrieval systems, an interesting product is SimpleIndex ' which complements both. SimpleIndex is designed to interface directly with both PaperVision and ViewWise, and so provides a simple, low-cost automatic scanning front-end.

In fact, SimpleIndex also includes its own low-cost searching and viewing application that can be used for basic document management tasks, and so SimpleIndex can be used as a standalone document management system, or added to allow the search and viewing of documents on other workstations.

Another document management product is DocuLex WebSearch. This system is a different in that it can automatically index all documents folder contents, similar to the way in which Google Desktop operates. Networked users are able to search on values in filenames, file properties or document contents. Additionally, users can access files via a website ' a big advantage for remote workers operating outside the confines of the office building.

5 Tips to Help You Buy a Digital Camera

2007-12-07T19:45:00.000-08:00

Buying a digital camera can turned into a difficult task. With hundred of cameras to choose from, its easy to get confused. The key to finding the perfect camera for your budget is to know a few things about what youre looking for. Use these tips to help you navigate through the world of digital photography and by the camera thats perfect for you. Decide on a Purpose: Why are you purchasing a camera? Is it for digital memories or masterpieces? In other words, are you buying a camera to take pictures of for yourself or are you taking pictures for professional reasons. There are many great compact cameras that are easy to travel or keep at home for spur of the moment pictures. There is also a great selection of cameras that are made for more professional or artistic photography. The more professional cameras are more expensive and will often have features you dont need and will never use. Shop Around: Different retailers will offer different specials, packages, and prices, so check out different stores and do some comparison shopping. Shopping around doesnt mean you have to drive from store to store; most major retailers will have websites listing products, prices, and any specials they may have. Use the money you saved to buy accessories that will come in handy. Digital or Optical: When purchasing your camera you will need to choose between optical and digital zoom. When at all possible, choose a camera that offers optical zoom. Digital zoom is a computer based image of what your picture should look like when you zoom in. This often creates a blurry or grainy effect when you try to enlarge pictures. Optical zoom provides a true image of the whether your zoom in or zoom out. Base your purchase on your purpose. If you are a photographer and you need to be able to zoom in and out while keeping a clear picture, choose the optical zoom. How Much Media do You Need: Your camera will most likely use up the available media memory. This is a case of bigger is definitely better. Even if you purchase a camera with a lot of memory its still a good idea to purchase at least one memory card. Again, if youre planning on taking professional quality pictures, you definitely will need to purchase back up memory. Higher quality pictures or pictures with more megapixels will take up more memory. Look for Pre Programmed Scene Modes: Scene modes are setting that prepare your camera for certain conditions. For example, you will be able to pick scene modes that will improve pictures taken at night or action pictures like sporting events. These modes are especially helpful for individuals who are just beginning their journey through digital photography. In a way, pre programmed scene modes are digital camera training wheels to help you learn to take great pictures. With a simple flick of a switch or turn of a knob youll be able to improve your pictures depending on your setting.

What is Computer Memory?

2007-12-07T19:37:00.000-08:00

Many people ask themselves "What is computer memory?" and with good reason. Computer memory can be a difficult concept to understand for most people. There are only two types of memory Ram memory and hard drive memory.

What is Computer Memory? Ram memory

"what is computer memory?" in reference to RAM memory. Ram memory is also known as random access memory and it stores information that the processor on your computer uses. Ram memory is made up of a module that has integrated circuits on it. The integrated circuits store information on them and that information can be accessed by the CPU in any way or form, that is why it is called random. The memory can be accessed in any way without moving or changing the module in any way. The only problem with RAM memory is that the moment the computer is shut down that memory is lost.

Unlike data previous data storage methods ram memory can pull data from any location within the circuits and other methods like tapes and magnetic disks require physical amount of the data or an optical reading unit.

Ram can also be written to, so essentially it can read as well as right. The problem is that ram memory loses its data as soon as the computer is shut down. This is where the computers flash memory or rom memory comes into play.

What is Computer Memory?- Rom Memory

Rom memory are small circuits of memory that are stored on the motherboard itself. Rom memory holds all the data that a computer needs to initiate and to start up. Rom memory is read only memory, so it cannot be changed and can only be read, that is why it generally only holds the firmware that the hardware needs to start. Rom memory only holds information that is not likely to change any time soon.

What is Computer Memory Hard Drive Space

Most people that use the computer, but dont understand how the computer works or what is computer memory. They think that Ram memory and Hard drive space are the same thing. In reality a hard drive is a metal platter that spins inside a metal case. As it spins the head can read and write information. So the hard drive is used to store long term and large files that can be accessed at a future time. Because ram memory cannot store anything, we use the hard drive to store information we need to access on another occasion.

It is a mistake that most people make when they refer to the hard drive as memory. In reality the hard drive is only a storage device.

What is Computer Memory and How Much do we Need?

Now that we have established that the hard drive is not and does not have anything to do with memory it is easier to realize the importance that ram memory has in our computer. That is why when you are choosing a new computer you should buy a computer that has as much Ram memory as possible.

VoIP Service - the best way to move forward

2007-12-07T19:36:00.000-08:00

Communication as we all know is an integral part of our life; something which we just can not function without. World has started shrinking with people having friends, relatives, business clients, dealers et cetera from worldwide. International calling or long distance calling is a lot expensive with traditional fixed line telephones that we have been using for more than a decade now. With this change has come a definite change in the way people view communication resulting in the need for a cheaper telephony.

Internet is one mode of connecting people. It has brought people from across the globe much closer. Gone are the days when you would use inland letters for expressing your feelings for your beloved or sending important information to a client from overseas. World wide web has brought about a revolution in the field of telecommunication by providing a platform for VoIP telephony.

VoIP service or voice over Internet protocol utilises Internet for call termination unlike fixed line phones or PSTN (public switch telephony network) which transmits calls via optical fiber wires. Few basics of this service are given below.

1. It works on packet switching capabilities and not circuit based thereby it is much more efficient than fixed line telephone network. Packet switching capabilities mean that it helps the voice packets take the route which is least congested. As a result there is no issue of latency or jitters.
2. VoIP call termination service uses a single network for terminating voice, video and data. As a result the resources are better utilised.
3. Since it functions mainly on the Internet which is relatively much cheaper than cables which have to be put across different locations to enable calling, the call tariff is very less. You can end up saving more than half of what you pay right now as your telephony bill!
4. With minimum hardware required by VoIP services, the cost of operations is further reduced.

Switching over to voice over IP is undoubtedly a great idea. However one should always do proper research by reading VoIP service reviews for instance, before selecting any particular VoIP service provider to ensure consistent and hassle-free service.

Document Imaging and Processing Typically Go Together

2007-12-07T19:07:00.001-08:00

Document Image Processing can be for different purposes.

For example, the processing might be nothing more than cleaning up the document. Typical documents often contain punch holes, black borders, undesired lines, and so on. There are document-cleaning tools that can remove these from the document images after they are scanned. Document cleaning software can also allow users to specify what to do about such elements in scanned images.

Other kinds of cleaning up include:

Straightening askew images
Removing borders that exceed given noise-tolerance specifications
Smoothing nicks and bumps distorting scanned text characters
Converting white text on black to black text on white

These and other cleaning tools can be automated by specifying minimum and/or maximum sizes of the elements to be removed.

Major Image Processing Tasks

In the case of text documents, document imaging produces images that humans can read, but machines can't. For making these documents searchable by using the typed words, the text characters on the images need to be converted into a machine-readable format.

This conversion is done using technologies such as OCR (Optical Character Recognition) and ICR (Intelligent Character Recognition). Even hand-printed characters can be recognized to some extent by these technologies.

This kind of conversion is also needed for the purpose of making the document images editable.

Once the images of text documents have been made machine-readable, the next, typical document imaging process is to index them. Indexing makes the documents searchable. Full-text indexing makes them searchable by any word in the document.

Full-text indexing takes up lots of storage space and an alternative is to index by tags and meta descriptions. Tags are words that typify the document's content. Descriptions give short summaries of the content.

The processing of the document images can go even further. Based on programmed specifications, the documents can be categorized and stored in appropriate repositories.

In short, document image processing can facilitate content management by converting paper documents into categorized content ready to be queried by users, all in a matter of minutes with minimal human intervention.

There are mailroom processors that can extract documents from envelopes and then go on to process the documents as above. With this kind of a facility, a single operator can manage mail volumes formerly handled by many clerks, and also go significantly further in the content-management process than the clerks.

Conclusion

Document imaging and processing typically go together. The processing can be simple tasks like removing undesired elements such as distortions and black borders or complex tasks such as converting text images into machine-readable characters and indexing the content.

How Automotive GPS Systems Work

2007-12-07T19:07:00.000-08:00

In recent times driving has become all the more simpler and exciting with the use of navigation systems such as automotive GPS systems. The time where you worried about getting to your intended destination is long gone because the automotive GPS system ensures that you get to your destination in due course without roaming about aimlessly and straying from your intended course. Honda was the first vehicle company to create the automotive navigation system as far back as the early 1980s, at that time a device known as an accelerometer was used in order to determine precise locations as the means to use GPS systems werent available. Nowadays you have a lot of popular vendors selling automotive GPS systems as well as other navigation systems and you are free to make an independent choice.

For those who have no detailed understanding of how automotive GPS systems work, they should understand that these systems make use of satellite signals in order to determine the precise location of a vehicle. Not all automotive navigation systems make use of GPS technology and certain differences exist with other GPS systems that use data on your precise position to superimpose it on a map and determine your particular location.

Different aspects make up a complete navigation system. These different components are the aerial view of the map which changes according to the motion of the vehicle; this component is easily the most crucial component, distance gauge, distance numbers as well as the next curves birds eye view in order to protect you from harm.

Navigation systems make use of road databases which contain a complete listing of the names and addresses of different locations which are stored as geographical coordinates. Any information that requires updating is supplied through internet technology as the vehicles moves from one particular location to the other. It also has a vector map of a particular area which ensures that it is easy to find a person or business if you have their particular name or address.

Databases which are employed in such systems can be easily kept on storage media such as hard disks or by using certain memory known as read only memory. Read only memory comes directly programmed from a factory or stored on other optical storage media devices such as CDs and DVDs. Base maps are usually stored constantly in the memory of the device because they dont change. The base maps are used to provide precise and accurate information about any current location that a user may find themselves in or which they may be interested in. Systems exist which allow for a combination of all these elements.

History has it that the navigation system that was primarily created to function with GPS was developed by Pioneer in the year 1990. Nowadays GPS navigation systems have come a very long way. You can use them not only to determine your location but to locate other essential services such as gas stations, restaurants and motels. Auxiliary functions which include messaging capabilities and the ability to watch DVDs may also come included.

CD And DVD Duplication: An Untreated Threat

2007-12-07T19:06:00.000-08:00

We are still used to the process of CD or DVD duplicating which a time is taking process and if we need more CDs or DVDs to burn, then its a nightmare. This problem can be solved by the best use of the processes of CD/DVD duplicators that are available in the market. This is a growing market with the increase of services. Especially for our small companies if there is a need to make copies of any software or any material to send to our clients, or to distribute to our employees then the valuable resources of time and human resource are wasted.

The CDs/DVDs duplication machines save a lot of time by duplicating more number of CDs and DVDs with automatic machines that use robotic arms, which reduces the manual process.

CD/DVD duplication is a method of generating CDs and CD-ROMs by writing empty CD-R discs in a CD-R drive on a PC or by using a CD duplicator. We can also define the CDs/DVDs duplication as, the replica of the optical media through a process of copying. In general we refer it as creating discs to limited extent, which is a contradictory concept to the large-scale process of replication. The content that is required to copy is usually, duplicated to existing record able CDs or DVDs media.

CD Duplication is typical process, where the lesser amount of CDs and DVDs are manufactured at present. The information contained in the CD-R or DVD-R is thus, loaded into the burners. And, your all information is extracted from the source in digital form, generally the CD-R, CD-RW, DVD+R, and DVD+RW will transfer in to the empty discs. The information that is transferred is thus typically verified moreover the disc will then accepted / rejected.

Also, with the increase of advance technology and reasonable price in information technology, many companies are offering similar level of CDs and DVDs duplication services.

The process of CD/DVD duplication is done in two methods. One process is a manual process and another one is automatic. The manual process is used for those who require less CDs or DVDs to duplicate. The automatic process is used by those who need more number of CD/DVD duplicates to be done in a much faster way.

No wonder, with the DVD duplicators we can make the second copy of CDs within 3 to 4 minutes. The automatic CD/DVD duplicators use robotic arms to transfer blank discs from one spindle to another, which facilitates the work instead of manual transferring. By using suction picker or mechanical picker the CDs or DVDs are transferred from one spindle to another. This is a better method of duplicating CDs and DVDs in bulk.

There are many companies that offer cheap services of CD/DVD duplicating process. Most of the services are available on the Internet and the orders can be given online. We can compare the products, their features and the prices to choose the best CD/DVD duplicating machines. Depending on the use and requirements the best machine should be selected or can hire the services if it is not needed.

Cisco Certified Internetwork Expert (CCIE)

2007-12-07T00:29:00.001-08:00

The Cisco Certified Internetwork Expert (CCIE) is the highest level of professional certification that Cisco provides. CCIE was the first Cisco Certified qualification, and as such there were no other certifications that could be taken prior. The development of the associate and professional certifications was due to recognition of the fact that a CCIE is over kill for many networking personnel, and also for the vast majority of businesses who employ such people, and that certifications needed to be offered at lower levels. Despite the development of the lower certifications, Cisco has chosen not to make them formal requirements for the CCIE certification.

The CCIE what CISCO describes as its "premium networking certification" is widely regarded as having one of the toughest, most demanding exams. It includes both a written exam and a day-long lab exam. This certification is aimed at senior level networking professionals who design, build, implement, maintain, or troubleshoot complex enterprise networking infrastructures. CCIE recipients can specialize in routing and switching, communications and services, security, or voice systems and technologies. CCIE Routing & Switching Routing and Switching is by far the most popular track, and covers a wide range of subjects, such as: LAN, WAN, Ethernet, TCP/IP, OSPF and BGP,IPv6 and many more. CCIE Security The Security track concentrates on network security and covers subjects such as ASA, IDS, IOS security, security and many others. CCIE Service Provider The Service Provider track focuses on networking in the service provider industry. Subjects include Optical networks, DSL, WAN switching, Voice over IP, Content Networking, Broadband Cable and Metro Ethernet. CCIE Voice The Voice track concentrates on voice solutions for the enterprise and includes subjects such as QoS, MGCP, Call Manager (Cisco's VoIP PABX), Cisco Unity (Cisco's Unified Messaging platform), Unity Express and IP Contact Center Express. CCIE Storage Networking The latest addition to the CCIEcertification tracks is the CCIE Storage Networking track. As the name suggests, the Storage Networking track concentrates on storage networking topics, such as Fiber Channel, iSCSI, FCIP, Intra VSAN Routing and FICON.

Efficient Methods of Diagnosing Strep Throat

2007-12-07T00:29:00.000-08:00

The efficiency of existing treatments in curing strep throat strongly depends on the accuracy and speed of diagnosis. In case the diagnosis is inaccurate or established late, the patients are exposed to the risks of receiving the wrong treatment (resulting in increased resistance of the bacterial strains involved in causing strep throat to medications) and of developing serious complications. The treatment of strep throat most often involves the use of antibiotics, medications that play a crucial role in eradicating the causative bacteria and preventing the occurrence of a variety of complications (acute rheumatic fever, kidney disease, coronary disease).

Considering the fact that strep throat (inflammation and infection of the pharynx with Group A hemolytic streptococcus bacteria) sometimes produces symptoms that are very similar to those of sore throat - the viral form of acute pharyngitis (inflammation and infection of the pharynx), doctors may confuse between the two, prescribing the inappropriate treatment and rendering patients more susceptible to developing complications.

In order to accurately separate between viral acute pharyngitis (the common sore throat and strep throat, doctors cant always rely solely on clinical examinations and patients reports of symptoms. In order to find whether the cause of pharyngitis is infection with viruses or bacteria, doctors often choose to perform more conclusive tests. The recommended supportive tests consist of throat culture and the antigen test.

Although the antigen test is quicker to perform, it is also less precise and therefore doctors may perform the throat culture test even when the results of the antigen test are negative. By performing both tests together, doctors can find conclusive data regarding the nature and the exact type of the infectious organism involved in causing acute pharyngitis. However, a good alternative to this combination of tests is the newly introduced optical immunoassay test (OIA), which is very sensitive and quick to perform.

Apart from these microbial tests, the diagnosis guidelines developed by the American College of Physicians (ACP) can also help doctors distinguish between cases of sore throat and cases of strep throat. These guidelines link the probability of Group A hemolytic streptococcus pharyngitis to the following clinical findings: tender anterior cervical adenopathy, tonsillar exudates, complete absence of cough and the presence of fever (bacterial infections are often associated with high fever, sweating and chills). These guidelines are considered to be very effective in diagnosing patients with strep throat and can in most cases replace microbial tests such as pharyngeal exudates, antigen tests and optical immunoassay.

Protect Your Family From The Dangers of Smoke and Fire

2007-12-07T00:28:00.000-08:00

Many people are hurt, lose their possessions and die because of fire. Although fire can easily be prevented it is one of the leading causes of injury at home in the United States. In some cases where individuals die of fire, it is because they were not aware that their house or the building that they occupy is on fire.

Fire alarm systems warn people of a potential fire. It warns the occupant while they still have time to either put out the fire or evacuate to safety. Most of today's fire alarm systems automatically call or notify the nearest fire department so that the fire will not spread out of control. Fire alarms are either set off manually or by heat detectors or smoke detectors.

Fire alarms are most of the time set to detect levels of heat or smoke which usually is an indication of fire. Many fire detection systems come equipped with flashing and blinking strobe lights for people who are hearing handicapped. Due to modern technology, fire prevention alarms are now incorporated with residential burglar alarm systems for the greatest protection and the best safeguarding of an individual's residence.

Smoke alarms are a component of any well designed fire prevention system, they sense smoke in the atmosphere of the room, closet or hall of a residence or public building and activate an alarm thus warning people nearby of a possible fire. Smoke alarms sense smoke today either by ionization or optical detection. Many smoke alarms also have carbon monoxide sensors that detect high levels of CO gas thereby providing protection from carbon monoxide poisoning.

The optical detector in smoke detectors is a light sensor which uses a beam like laser. These beam sensors then sends a laser like beam to other sensors, if smoke is non-existent, the laser like beam passes through the optical chamber of the light sensor in a straight line. If smoke is present, the laser like beam is scattered by the smoke particles as it enters the light sensor and the scattered light then triggers the alarm of the smoke alarm.

Ionization detectors are much cheaper than light detectors, although these types of smoke detectors are discouraged from being used because of environmental reasons. Ionization detectors work by detecting particles of smoke by a small amount of radioactive "americium-241" (that is why it is discouraged from being used). This radiated material goes through an ionization compartment. This chamber permits the steady flow of current of electrodes, so that when smoke particles enter this chamber it interrupts the flow thus setting the alarm off.

Some fire alarm systems have sprinkler system that will contain or put out the fire before it becomes uncontrollable. However the only way to prevent fire is to take steps to be careful and take additional preventive measures.

Aviator Sunglasses

2007-12-05T20:31:00.001-08:00

Aviator sunglasses are characterized by their oval shaped lenses that narrow towards the bridge of the nose. Aviators are one of the oldest designs of sunglasses and still the most commonly preferred all over the world. When it comes to sunglasses, aviators are considered classics.

Aviator sunglasses were designed in 1936 for military use. The seemingly humble pair of aviator sunglasses was, in fact, useful gear for the armies in the Second World War. Since then, they have evolved greatly and contemporary aviator sunglasses are trendier and sleeker, with additional features like photo-chromatic lenses and gradient lenses.

Aviators are androgynous, meaning that both men and women can wear them. They are usually preferred in black and brown tinged lenses, but green, blue, gray, and violet lenses are also quite popular. They also come in a variety of frames, with gold plated frames being the most favored. The frame of these glasses is very lightweight and thin so as not to add to the overall weight. Plastic frames are less expensive but do not look as dynamic. Aviator sunglasses may have one or two bridges over the nose to connect the two oval lenses.

Lenses of aviator sunglasses can be made of polycarbonate plastic or glass. Plastic reduces the weight of the lens, but glass is more scratch-resistant. The lenses not only block most of the sunrays from entering and harming the cornea, but they also block out harmful ultraviolet radiation.

Though the primary objective of the aviator sunglasses was something altogether different, today they are used mostly as a fashion accessory. Pop stars and movie stars throughout the ages have popularized aviator sunglasses. They are ideal for blocking out the sun on beaches, golf courses, and summer picnics. A good pair of aviator sunglasses does not create any optical distortion and provide healthy protection for eyes from intensely bright sunlight.

Aviator sunglasses generally cost upwards from $50 and the cost may go up to $100 or more depending on the brand manufacturing them. Ray-Ban, Oakley, Dior, and all other popular brands have their own designs of aviator sunglasses.

All about USB Flash Drives

2007-12-05T20:31:00.000-08:00

Out of all the components in a computer, one of the most important is the data storage device. With more and more data being generated, there is an increasing demand for better data storage devices.

Data storage technology has improved in leaps and bounds over the last decade. Firstly, there has been a dramatic increase in the capacity of storage devices such as DVD, CD and even Floppy disks. Secondly, numerous new storage devices have been introduced, some of them completely solid state (no moving parts) like CD, DVD, flash drives, zip drives and memory cards. Thirdly, the technology has moved from a mere magnetic storage to optical and magneto-optical drives.

Even the hard disk which traditionally meant a stationary or fixed storage device is becoming removable. The storage devices are coming in many forms: traditional discs of varying sizes from 5 to even 0.3, key chain devices (flash drives) and stamp size memory cards.

They are no longer used with PCs alone but also with cameras, mobile handsets, PDAs, MP3 devices, Auto PCs and GPS devices.

The information stored is not just programmes or data. It includes songs, movie clippings, video clippings, photographs or maps. Also, with medical imaging equipment going digital, very soon the content could be ultrasound, X- ray, MRI or CT scan images.

The personal storage technology has improved out of the need to provide faster, larger and better storage facility. There are four goals leading this phenomenal growth. First is to push the limits of packaging density so that one can store more data in less space. Second tries to make them more reliable with long life. The third goal is to consume less and less electrical power and the fourth, of course, is to make the devices more affordable.

Data storage memory is primarily of two types. The primary memory is the volatile memory and is erasable. The secondary memory is non-volatile and is of a more permanent nature. Basically, when talking about the data storage devices, it is generally assumed to be about the secondary memory.

Secondary memory is used to store data permanently in the computer. The secondary storage devices are usually as follows:

Hard Disk Drive: This is the most common type and is used in almost all computers. The others include the floppy disk drive, the CD-ROM, DVD-ROM, and the flash memory (USB data card).

Out of these, the USB flash drive is playing an important role in the market. The high points of a USB flash drive are its size and capacity. It actually behaves like a portable hard drive. It can be used for transferring the data and also for the backup or archiving of small but essential data.

Each USB drive is made up of a case of tough plastic or metal containing a printed circuit board that contains NAND flash memory to store digital data. The entire assembly has a single USB connector which is inserted into a USB port when in use. USB drive offers solid state memory.

Venture Into Internet Phone Service To Earn More!

2007-12-05T20:30:00.000-08:00

We have been using fixed line telephones or PSTN (public switch telephony network) for more than a decade now. Excellent quality and reliability are two features that sets it apart from other forms of communication and has kept its users satisfied till now. However with changing times the need and requirement of people too have changed. Owing to globalisation frequent long distance international calls are quiet common. In such a scenario making calls using PSTN can prove to be quiet expensive on your wallet.

When there is a need there is a solution too. This solution has arrived in the form of Internet phone service. Internet phone or PC to phone as it is often referred to as is, at present, one of the most cost effective as well as easy method of calling. As evident from the term itself, this one-of-its kind Internet phone service uses Internet or world wide web to transmit calls unlike PSTN which sends calls over optical fiber wires. It is primarily because of this reason that it helps to cut down on your telephony expenses to a whooping 40% and more!

Making Calls From PC To Phone

In order to make cheaper calls through your computer you just have to download a simple dialer from the internet; the link to the website would be provided by your service provider.

Next, simply put in your complete destination number(along with the country or area code) in the dialer and click on the dial button. Voila! In no time you are connected to your loved ones!

Making Money From Residential Phone Service

With increasingly large number of people opting for PC to phone service, it is the ideal time to become a service provider for the same to get the most out of this opportunity. However, you would need to make a huge investment in order to procure and maintain the infrastructure and the technical equipments needed to get into the broadband phone service business.

A better and more convenient option would be to search for a provider whose offering a ready made PC to phone service platform. This would not just save you from spending an exorbitant amount as capital but the operating cost too would be quiet affordable. This in turn would minimise the risk factor that comes along with every new venture that you take up.

How To Search For The Best Service Provider

Every provider of VoIP phone service offers different service. The best option for you would be to look out for a provider giving you ease of account activation and management facility so that there are no hiccups during the start up of your new venture. There are certain providers who give you the opportunity to sell the service on your brand thereby making it easier for you to capitalise on your band image.

Besides this one must ensure that you are being provided with online panel for creating and managing user accounts. This would help you to handle your business in a more organised and controlled manner.

The Past And Present Of Computers

2007-12-03T18:59:00.002-08:00

Computer (computador) is an appliance which can manipulate data in accordance with a list of instructions. It is a type of data processing system.

Today the computer (computador) has become indispensable in every household and comes in numerous physical forms. The first modern day computer was developed in the mid-20th century, though the concept of computer (computador) and various similar machines existed before. It actually started in 1837, when `The Analytical Engine`, the first fully programmable mechanical computer, was designed by Charles Babbage.

The Earlier versions were huge and bulky and used up a whole room. The device EDSAC (Electronic Delay Storage Automatic Calculator) was one of the very first computers that could implement the stored program architecture. In comparison to them, modern computers (computador) have tiny integrated circuits and are much better in terms of capacity and speed as well as accuracy. Today`s tinier version can even fit in your wrist watch and are powered from the watch battery. Personal computers can be found in almost every house today and in various forms. They are in fact the icons of the information age.

What makes computers (computador) highly versatile and distinguishable from other appliances is that it can be programmed. A calculator can only calculate, just like a washing machine can only wash, but a computer can be programmed to do any kind of job. Software programs are a list of instructions that can be stored and executed by the computer.

A general computer (computador) has four major sections, the arithmetic and logical unit or ALU, the control unit or CU, memory and the interface for input and output devices. These parts of computer are interconnected by busses. The ALU, control unit, registers, and the interface for input and output devices are collectively known as the central processing unit or CPU. The Early CPUs used to be composed of different separate components, however since the 1975; the CPUs are being constructed on a single integrated circuit, the microprocessor.

The ALU is for arithmetic and logical operations of the computer while the control unit is for directing the various parts of a computer (computador). Its job involves reading and interpreting the instructions of the programs one by one and converting them into control signals for operating other parts of the computer.

The earlier version of computer (computador) used Magnetic core memory but today it has been replaced by the semiconductor memory. The main memory of Computer is divided in two parts, RAM or random access memory and ROM or read-only memory. RAM can be written and read anytime through CPU commands. On the other hand, ROM is pre-loaded with software and data that never changes, and it can be only read by the CPU.

I/O is hardware by the means of which a computer(computador) can receive information from the outside world and also sends back results. Common input devices are the keyboard and mouse. While common output devices include monitor and printer. There are some devices that serve as both input and output devices like Hard disk drives, optical disc drives, floppy disk drives etc.

History And Uses Of Optical Microscopes

2007-12-03T18:59:00.001-08:00

Optical microscopes use visible light and a system of lenses to magnify small samples that are usually un-seen to the bare eye. The optical microscope is the first, oldest and simples type of microscope (as opposed to the much more advanced electronic microscope). The first optical microscopes were created in the 18th century. Due to it's compact sizes, simplicity and relatively low price, the optical microscope is very popular, and can be found in use in many areas of biology. Optical microscopes mostly magnify objects for up to 1500 times.

The first optical microscopes were structured in a way that is called "the simple microscope". This structure utilizes only one pair of lenses to create a magnified image of the sample. Today, the simple structure is in use only in the magnifying glass, hand lens and the loupe.

The more advances optical microscopes, and the ones that are popular today, are what's called "compound optical microscopes". These microscopes use a system of many lenses, in order to "compound" and multiply the magnification, and therefore maximize it. The two main lens systems in an optical microscope are the objective lens (near the examined object), and the eyepiece lens (up near the eye of the scientist). Modern optical microscopes use multiple lenses both in the objective part as well as the eyepiece part. The old optical microscopes also used a mirror to provide illumination below the object. The modern optical microscopes use a strong lamp to provide constant and strong illumination.

So what are optical microscopes used for now a days? The main uses of compound optical microscopes include:

The examining small pieces of material, or even a smear or a squash preparation. This is due to the fact that the optical microscope uses light to pass beneath the object and enter the lenses. That's why the item is better be half-transparent. In other uses the optical microscope may be used to examine metal samples, in order to study the metal's structure. At low power, microscopes can be used to examine small living animals and plants. At high power, they can be used to examine bacteria.

It is important to note that the vast advancement in medicinal fields and biology in general, is owed to a large extent, to the invention of the optical microscopes. For example, the way the blood flows in our body was not fully understood until the microscope made in possible to examine small blood vessels behavior.

PC To Phone Service a service to look out for

2007-11-29T17:45:00.001-08:00

In today's global economy the status of communication has augmented a great deal. Both residentials and business houses are in the look out for a cost effective mode of communication. Calling through standard telephone lines prove to be quiet costly especially when you have to make long distance and international long distance calls.

VoIP or IP telephony has arrived with a big bang and is proving to be the biggest challenger of public switch telephony network. It helps in terminating calls via the Internet instead of relying on optical fiber wires unlike PSTN services.

The first VoIP applications used computers as a terminal which was attached with headphones and speakers in order to access VoIP network (known as PC to PC service). However the quality of service offered by VoIP proved to be the chief reason for its inability to gain popularity. Things have changed drastically with consistent improvements being made in the field of IP telephony.

With the developments being made in this field, you can now make VoIP calls through PC to phone. This service is not just cost efficient but it is also the best way to get the most out of your computer.

The demand of PC to phone service by the residential users is increasing by leaps and bounds. This is the best time to set sail in this service in order to capitalise on the rising demand of internet phone system. If the only that is stopping you from entering into this field is the cost involved then you can thank your stars. Few pro active VoIP providers perhaps anticipating this have started providing VoIP phone service platform.

Benefit Of Internet Phone Service Platform

The platform provider ideally provides a one stop solution to those interested in starting their PC to phone business. From infrastructure to entire hardware equipments everything is owned and managed by the platform provider and hence your investment according in this new business would be minimal.

World War II Foo Fighters

2007-11-29T17:45:00.000-08:00

In the 1938 comic strip Smokey Stover, a firefighter was known for his line, "Where there's foo, there's fire." From Smokey, aircraft pilots borrowed the term "foo fire" to describe the various unexplainable phenomenon seen in the skies over Europe and the Pacific theatre during World War II. While Allied pilots initially thought the flying objects were German secret or psychological weapons, after the war it was discovered that sightings were also reported by the enemy, who had assumed the crafts were US-made. To this day, the sightings remain a mystery.

Over the course of the war, fireballs, estimated to be as big as 3wholesale pearl wholesale necklace00 feet and as small as 1 foot in diameter, were reported and thoroughly documented. These apparitions left witnesses awe-inspired, wary, and frightened-although the foo fighters never harmed or attempted to harm anyone. The CIA was commissioned in 1952 to study the reports and concluded that while mysterious, foo fighters were not a considered a threat to national security.

A Foo fighter is an umbrella term that includes flying objects of various shapes and sizes. Wobbling, or vibrating flares were described as glowing globes of intense green, yellow, red, orange, or white lights. One crew even reported observing the phosphorescent spheres going through a sequence of color changes at regular intervals. Other reports describe them as silver or gold metallic, and disk-shaped. They frequently appeared at the wing tips of planes in pairs or alone, although sometimes they were found in larger clusters of fifteen or more. In one report 150 objects were estimated to be arranged in 10-12 lines. Picking up an aircraft, these blobs of fire could reportedly pace a plane at very high speeds through extensive evasive maneuvers for several minutes. One British officer and his crew of sailors tracked an object from the deck of their vessel for over an hour. Although a few baffled pilots attempted to intercept, and even fire upon the globes, their efforts were unsuccessful, and the objects usually zoomed away of their own accord.

Foo fighters were mentioned in the American mass media. Ponderous articles appeared in Time and Newsweek in 1945, contributing to the wave of UFO consciousness building in the US. By 1952 so many civilians were contacting government agencies regarding UFO reports that regular intelligence work was being affected.

While scientists have never been able to explain the phenomenon, many speculations have been advanced as possibilities. Five of the most plausible theories are:

1. The fireballs may be nothing more than St. Elmo's Fire, a reddish brush-like discharge of atmospheric electricity which has often been seen near the tips of church steeples, ships' masts and yardarms. It also appears at a plane's wing tips.

2. They may have been optical illusions, mere after-images of light remaining in pilots' eyes after being dazzled by flak bursts.

3. Occurrences may have been the rare effect of "ball lightning," a glowing, drifting bubble of light typically eight inches in diameter. These generally, though not always, follow regular lightning strikes.

4. Bright ground objects reflected from the curved plastic canopy of an aircraft can be perceived as images above the horizon.

5. Proponents of the extraterrestrial hypothesis (ETH) have suggested that foo fighters are hard evidence of ETs visiting earth.

Foo fighters are certainly some of the best documented reports of UFOs, and photographs and respected testimony abound. Hopefully in time the mystery will be solved, and this comic book name will be replaced by its true name.

8 Ways to Reduce or Even Eliminate Computer Vision Syndrome

2007-11-29T17:44:00.000-08:00

Over the past week "Computer Vision Syndrome" has been in the news. The latest story in "The Frederick News-Post" titled "Prolonged computer use can lead to vision problems".

The article states that more than 88 million people who use computers for more than 4 hours per day suffer from computer vision syndrome, that's about a quarter of the total population of the U.S.

The Bureau of Labor and Statistics estimates state the enormous cost for workman's comp, to the economy, and employers: In 2002, employers reported a total of 487,900 lost workdays due to work-related musculoskeletal disorders (MSDs), representing nearly 50% of all lost work days. On top of these productivity costs, employers have paid approximately $20 billion annually in direct worker's compensation costs. Indirect costs, like lower productivity at work, etc. add another $60 billion, for a total of $80 billion dollars.

The articles quotes Dr. Frishman, an optometrist from Frederick, Maryland, that the top of the monitor should be at the same level when you stretch your arms out. That would mean that I had to dig my monitor into my desk. The correct location of the monitor is: top of screen at or just below eye level, not shoulder/arm level.

Here are some tips to reduce or even eliminate most symptoms:

1. Use a TCO'03 compliant monitor. Not only are they more environmentally friendly than other monitors, TCO'03 also requires compliance with ergonomic standards: contrast, resolution, brightness, adjustability, etc. Make sure that the LCD monitor you use has a "Class 1" rated LCD panel built in. If the literature that comes with the monitor doesn't explicitly say "Class 1" it probably is not.

2. The area behind the monitor should be lit, too. If it is all dark around your monitor (or TV for that matter), the eye has to constantly adjust between bright and dark. Use a light colored keyboard.

3. Dark, black keyboards create eye strain for the same reason. Ideally, the area on your desk where the computer is should be in "lighter" colors.

4. If you need reading glasses, they won't work with your computer. The monitor should be about arms length away (25 inches), books and papers only about the length of your forearm (15 inches). Ask your optometrist what he can do for you. Zeiss Optical has special lenses called "Gradal RD"

5. Avoid glare, reflections, etc. from windows, lamps, etc.

6. Look away from the monitor at least every 15 minutes. Look out the window. In Germany for example, regulations require that every computer worker has to be able to look out a window without getting up. The eye is relaxed when you look into the distance but contracted when you look on closer objects.

7. Human attention span is typically between 20 and 45 minutes. Find your attention span, set an alarm and walk away from your desk for a couple of minutes, stretch, go for a little walk and breath deeply. Do not look at literature or anything close.

8. If you use a notebook, the notebook has to be off your desk to bring you monitor to eye level. Get a notebook stand. This will also prolong the life and increase the stability of your notebook, because it runs cooler. Don't forget to remove the battery when it is charged.

What is your next step to reduce your computer eye strain?

“嘀嘀！”从后面传来两声车鸣，李天没有在意。

“嘀嘀……！”这个时候，一辆白色的宝马高级轿车在李天的身边停的下来。李天转头一看，心理不由苦笑，不是别人，正是许洋。看来今天是躲不过了。

当李天转过头，宝马的车窗拉了下来。

“许总，有什么事情吗？”李天问道。

“上车！”许洋看着李天，面无表情的说道。

“上车？”

“快点！”

听见许洋的话，李天无奈，最后只好上了许洋的车，车子再次缓缓的开动了起来。两人坐在车中，谁也没有跟谁说话。

“不给我一个解释吗？”过了许久，许洋看着前方对李天说道。

“解释？什么解释？”李天也猜不出来许洋到底是为了什么而要解释，所以只好问道。

“为什么要去酒吧做兼职，你很缺钱吗？”许洋面无表情的问道。

“算是吧！”李天回答道，因为他也找不出其他的理由。

“喝几千元红酒，也有缺钱的时候？”许洋继续问道。

“就是因为喝所以才缺钱的！”李天顺着许洋的话说道。

“以后不许再喝酒了！”许洋用命令的语气说道。

“为什么？”李天不解的问道。

“因为……。”说到这里，许洋一愣，也不知道自己该怎么回答。

“因为酒是穿肠毒药，我不想公司里面出现一个浑身带着酒气的酒鬼！”许洋对李天说道：“更何况你晚上到酒吧简直，没有充足休息的时间，第二天到公司后精神一定会有问题，所以你以后也不要去酒吧当那个什么调酒师了！”

“这你可就说错了。适当的饮酒可以促进血液的循环，有力于消化，吃饭时还可以开胃。”李天不同意道，让他不喝，还不如杀了他痛快。

“那是只适当，你觉的你喝酒是适当吗？一下子少说也要两瓶，两瓶多少钱？几千还是过万？”许洋皱着眉头对李天。

“那也没有办法，我也没有其他的爱好了！”李天摊了摊手说道。

“你是我们公司的职员，我不想因为酒而毁掉你的前途。”许洋继续对李天说道。看见李天没有说话，许洋想了想说道：“这样好了，你退一步我也退一步，一天只喝一杯，怎么样？”许洋建议道。

李天听见后还是没有说话，凭什么样让自己听她的，只因为她是公司的老总？下班时间属于个人，也碍不着她什么事。

“你和阿凤是怎么认识的？”许洋看见李天没有说话，继续问道。

“恩？”李天转过头看着许洋，难道她看出了什么？不会吧，自己掩饰的很好呀！、

“就是严凤，你和她是怎么认识的？”许洋问道。

“就是你让我陪酒的那天认识的，你知道的！”李天小心翼翼的解释道。

“就这么简单？那你怎么会去她的酒吧应聘呢？”许洋听见后又问道。

“我也不知道她就是那家酒吧的老板。我只苏茜黄是北京酒最好，美女最多的八个酒吧之一，所以想去试试，顺便看看那里还有什么隐藏的好酒！”李天说道。

“恐怕你不禁是冲着酒最好去的吧？美女最多是不是也是你去那里的主要原因？是不是觉的一个摇来摇去，变换花样的调酒能吸引许多女孩子的注意，是不是会感觉特自豪？”许洋对李天逼问道，显然李天刚才回答她的答应另她不满意。

“我怎么觉的你的话里有刺呀？”李天歪着头看着对方问道。

“有没有刺你心理明白，公司有条例，正式的职工禁止在其他公司或场所兼职，作为一个主管，你难道对这些事情都不知道吗？你不觉的影响公司的形象吗？要是让可户看见你会给我们公司带来多大的影响吗？”许洋转过头看着李天狠很的说道。

“可我现在不是公司正式的职工，时期期为两个月，我现在还在实习期间，这就说明我还有权利做兼职。我的形象怎么了？我自我感觉还不错呀！”李天指了指前面回答道，提示她开车应该目视前方他可不想就这样英年早逝。

“我要求你以后禁止喝酒，禁止到外面兼职，你答不答应？”许洋没有把李天的警告让在眼里，依然紧紧的看着李天。

“为什么？为我一个合适的理由？”李天说道，本来自己也没打算在酒吧干活的，今天只不过是为了应付一下场面而已，没有想到许洋竟然连自己喝不喝酒都要管，李天不禁和她对着干上了。谁怕谁？大不了一起撞车。

“我说，不许喝酒，不许到酒吧做兼职！”许洋看狠狠的看着李天一字一字的说道。

“你不是说一天一杯吗？怎么又不许我喝了？再说喝酒和兼职是我自己的事情，与许总你好象无关？再说，现在是下班时间，你没有权力也没有人赋予你这个权利来管我，我想做什么事情就做什么事情和你好象没有丝毫的关系，你又不是我什么人，即使是，也管不了我！”李天觉的对方的条件停无理的，而且还拿出一副命令的样子，好象谁欠她似的，把自己当女王了。

“滋……！”一个急刹车，车停了下来。

“你疯了，想死别拉着我！”李天被一晃，头正好撞到了车窗上，对着许洋不禁怒道。

“下车！”许洋冲着李天冷冷的说道。

“开什么玩笑，这里是高速！”李天看着许洋说道。

“我让你下车！”许洋再一次对李天说道，眼睛狠狠的瞪着李天。

“要不你再向前面开一点，下了高速我再下？”李天商量的说道。

“我刚才和你商量，你答应我了吗？”许洋看着李天说道。



看着过往的车辆，没有办法，只要伸手准备搭便车，可是过了十多分钟，车过去了好几百辆，就是没有一个人停下。

T1 Internet Connection

2007-11-26T23:21:00.002-08:00

T1 carrier is one of the most popular leased line options for digital transmission that offers high speed internet connectivity at 1.544Mbits per second. Is capable of carrying 24 digitized voice channels at the speed of 1.544 megabits per second.

T1 carrier is one of the most popular leased line options for digital transmission that offers high speed internet connectivity at 1.544Mbits per second. A T1 line is comprised of 24 individual channels, each capable of transferring data at 64Kbits per second. With T1 Internet connection, you can have uninterrupted and reliable data transfer within seconds. In normal phone lines, voices are transmitted through copper wires as analog signal and you can transmit data at around 30 kilobits per seconds with your normal modem. A T1 Internet connection, on the other hand, is capable of carrying 24 digitized voice channels at the speed of 1.544 megabits per second. A T1 carrier can carry 192,000 bytes of data per seconds nearly sixty times more data than that of a normal residential modem. T1 Internet connection is capable of providing uninterrupted data transmission which you would not get if you use ordinary modems. If you want to transmit audio or visual data through your residential modem or through your phone service you have high risk of getting jammed since the speed is so slow. With a T1 service, you can eliminate this risk significantly.

Internet service by service providers convert all voice calls as analog rather than in digital format, which not only takes longer time but frustrates customers now that high speed is available. With a T1 line, you not only increase the speed of your data transmission, but also save time for your valuable online work. With the advancement of fiber optics, lesser time is required to convert analog signals to digital format. Fiber optical wires are sometimes used for T1 line to provide maximum speed, although the normal wires are by copper. In case of ordinary modem or residential telephone connection, thin copper wire is used which can rarely carry much load at the time of transmission of data. In T1 Internet connection, broadband internet connection is used which ensures two-way transmission of data at a faster rate than any other method of transmission. Apart from that, hundreds of users can comfortably share T1 connection, which is impossible if you use modems or telephone line or an ISDN line. If you are interested in online songs and movies, then you will find the ordinary modem or residential telephone service can not meet your demands, as these lines take hours to convert any MP3 files or video files to analog format and to transmit them at the desired destination. A DSL or cable may be options but a T1 line, if you can afford it, is the best option. For a business of 20 or more employees, a T1 service is required. By implementing T1 circuit, you can easily transmit digital and video data at the required destination at great speed and at the same time, have a T1 service thats more reliable.

How to photograph jewelry

2007-11-26T23:21:00.001-08:00

Photographing jewellery can be tricky, but with a few concepts and budget below US$500 it is possible to achieve near-professional look of the photographs. This guide is intended for absolute beginners. Terminology is simplified, and camera adjustments are discussed with only jewellery in mind.

1. Equipment

1.1 Digital SLR

Biggest spend for near-professional look of jewellery photography is for the digital SLR. This is an absolute must. Second-hand camera will be as good. Camera without many features and without high Mega-Pixel rate will work just as fine. 3 Mega Pixel is more than enough.

Note that what makes the difference is the quality of the optical system, not the number of actual pixels.

Digital SLR will allow you to manually adjust every aspect of the camera. Automatic modes are not appropriate for jewellery.

1.2 Lighting

Avoid using any flashes. Don't use camera's built in flash. Don't buy stand-alone flashes. In fact, don't buy any lighting equipment. Desk lamps 60W-100W will do just fine.

Photo tent will help a lot, but is not mandatory. You get find them for as little as US$20. Terminology varies, so "Photo Tent" will also be called "Light Cube", or "Soft Light Box". Do your searching and find one approx 20" (50cm) in size.

You will need 3 lights. Two matted lights -- soft lights, and one reflector light. Place one matted light left of the area for jewellery, and one to the right. Place reflector light near where the camera is.

Whatever you do, avoid mixing light types. Use only non-fluorescent lights, and isolate your photo 'lab' away from natural light.

1.3 Tripod

To have freedom with many settings that will be a must, we will have to use longer exposures. For longer exposures to achieve maximum sharpness, we'll need a tripod. Our hand shakes too much, when camera runs at exposition 1/2s or 1/5s. Buy a 'tripod' for US$10-$20. You don't need a heavy duty tripod. If your setup will be on a desk, you can chose mini tripod - approx 10" (25cm), and stand tripod on the desk as well, or longer tripod, approx 50" (125cm) and stand it on the floor.

2. Setup

Position the lights as described above. Two desk lamps with soft light (irrelevant if you are using photo tent -- the tent is there to soften the light), and reflector light at the front. I keep the cube open at the front, for easier adjustments and photographs, unless jewellery is highly reflective of the image of me taking photograph.

Uniform background colour is recommended. White background works great. Black background is a little harder to work with. I use one of the white wooden shelves that was sitting in the garrage. Hardware stores will sell these for a few dollars.

Jewellery neck stands look effective only on some pieces, but for most laying on the white surface is the best.

3. Jewelry Arrangement

Spend time arranging jewellery. Clean the jewellery if needed. Polish and remove finger prints. Lay it nicely. For chains, spend time to even out all links and to lay it in a perfect circle. For fashion jewellery this may be a little tricky simply because it's made of various materials and it just doesn't like to sit perfectly on its own. Use blue-tac to fix it where you want it.

4. Taking Photographs

Set your camera to manual. This is where you can adjust all settings yourself. You can leave auto-focus on if you wish, that is about the only setting you can have automatic. Disable camera flash. With static lighting and without using flashes, you can spend time moving the lights until you get perfect setup, before taking shots.

Learn the following 5 camera adjustments: Aperature (f-number), Sensitivity (ISO number), Shutter Speed (Exposure), White Balance, and Focus. These 5 are your bread and butter.

4.1 Aperature

Also known as f-number. This setting widens or narrows the lens, limiting the amount of light that comes into the camera. This directly affects shutter speed, and film sensitivity (since we're using digital camera, film sensitivity is adjustable like anything else).

This setting is responsible for the 'focal lenght'. With high f-number eg f/22 or f/11, when taking jewellery photographs, parts that are close to camera will be focused as well as parts that are further away. With low f-number, eg f/2, only the focused part will be in-focus, and parts of jewellery that are further apart or closer to the camera will become fuzzy. Use this setting as it suits you. You may want to create certain effect, but if you don't, keep this setting to f/11. Overdoing this setting will limit the light coming into the camera, and you'll have to make sacrifices elsewhere to compensate.

4.2 Sensitivity

Also known as ISO number. This used to be film property, and expressed in numbers like ISO200, ISO400, ISO800 etc. The higher the number, more sensitive the film, less light it needs, and thus more expensive. In Digital SLR's this is merely just a setting, but the higher the number, more noise camera will capture. The more light you have, you can go lower with this number. For our limited lighting, ISO800 or ISO1600 will be fine, but try not to use ISO3200 -- it adds visible noise.

4.3 Shutter Speed

Also known as exposure, it is a measure of time camera will be taking the light. When photographing moving objects, you would want this fairly short: 1/200 or or 1/400. However, we're taking static objects, and with the tripod camera is static as well. This gives us flexibility in going as low as 1/30 or 1/10, or even 1/2. Value 1/2 means that camera takes light from the object for half a second. If anything moves during that half a second, photograph will be blurred.

Adjust shutter speed freely until you get desirable effect. In fact, when taking photographs of jewellery against white background, you will want photos over-exposed. Over-exposure should affect only the white background, where small imperfections of white surface will vanish into pure white. If your camera has light meter, it will display a warning that you have too much light, number 2 or 2.5 could be flashing in your viewfinder. This is good :-).

If your background is black, you'll want it under-exposed. This will keep the black background black, remove some imperfections, but leave the jewellery just fine.

4.4 White Balance

With different colours present in every light source, our eyes naturally adjust to what white is. Cameras try to do the same and for general photography are quite good at it. However, for jewellery, you'll want to try all manual pre-sets yourself and chose best result. If everything fails, manually adjust white balance, until it's good. You won't need to keep changing this setting from one jewellery piece to another.

4.5 Focus

Jewellery is static. It's easy to use manual focus, but auto-focus seems to work just as fine. If camera keeps focusing on the incorrect part, just switch to manual, and away you go. For most applications, auto-focus will be fine though.

4.6 Taking photographs

Take enough photographs for each peace. Use camera built-in display as a guide only. Colors and brightness will look slightly different on the computer screen. You can adjust some of it afterwards, but try to take a perfect shot in the first place.

5. Post-Processing

Restrain youself from using too many features of the photo editing software. All you need to do is manually adjust Brightness and Contrast, and perhaps use 'Sharpen' feature. Don't apply any automatic adjustments, as these will get confused with too much white in the photo, or too much black.

Crop to the area you want to keep, save in internet-friendly format (eg 400x300) and you've got a near-professional photograph. Reuse the same photograph for 'zoom-in' crops. You won't be making images larger, instead you'll be cropping from your original, adjusting and saving.

Digital camera with 6 mega pixels or more will preserve enough of the detail for zoom-in's. If not happy, re-take photos of the detail.

Lightweight Television Comparison

2007-11-26T23:21:00.000-08:00

In the past, televisions have been heavy and bulky because a regular cathode ray tube (CTR) TV needed the extra room to enable the visible screen and its scanning picture process the room to work. Today we have the convenience of having magnificent color as well as a lightweight television. These lightweight colorful televisions are Plasma, LCD and DLP TV's.

1) How Plasma, LCD and DLP work

Plasma - Florescent light is the sustaining component of a Plasma TV. Florescent is a matter of gas. Launching electrons into the florescent gas causes the electrons to react quickly. The electrons slam into the atoms, it is much like watching a pinball game in action.

In plasma connected to electricity the negative and positive particles are running at each other. While they are running at each other, they are of course bumping into each other. While striking against each other they display an illustrious intensity of ultraviolet light. This is then displayed upon a screen by several layers of glass with contained gas cells and electrode grids.

LCD - Liquid Crystal Diode - Liquid Crystal is one of those amazing things that are in a state of being more than one matter. Liquid Crystal is multi mattered, just as we are. People are solid, liquid and gaseous, yet we are neither. Therefore, it should not be so hard to understand that LCD is multi mattered.

A heat process that by nature transforms liquid crystal into another aspect of itself that is heat changes the Liquid Crystal into a more liquid than solid matter. As a result, anything made of LCD is temperature sensitive. For instance, a computer monitor or thermometers reaction to hot and cold, as people do shiver and swelter. Liquid crystal is used for many things because of its nature when introduced to polymers, such as bulletproof vests and sails for boats.

With the use of electricity, LCD is able to cast a picture by distributing the crystal-clear sequence or design of blocked light molecules. This in turn manipulates light intensity of its pixels that forms upon the colorful screen face.

DLP - Digital Light Processing

Digital light processing uses technology that is based on optical semiconductors. This digital micro mirror device uses tilting mirrors of aluminum, which uses reflected light and a color filter wheel, to create a picture. The mirrors are laid out in a matrix pattern and each mirror equals one pixel. It is like looking at a photo where each piece displays a small square shaped light reflection. The further away you are from the TV screen the more the picture appears to blend together.

The reflected light is directed through a lens and then onto the TV screens producing the images we see.

DLP TV's are not prone to phosphor burn in, nor are they vulnerable to pixilation where the find lines of the pixels separate.

Current DLP TV's are now made slimmer and more lightweight than in the recent past.

DLP technology is used in many ways besides TV screens, which range from business projectors, video walls and home theaters with more experiments in future uses. DLP is also used for commercial entertainment applications and projection systems used for large group viewing.

5 Materials and Technologies That Just Might Eliminate Digital Camera Shutter Delay

2007-11-25T21:16:00.000-08:00

Bob pushed the shutter release button andNOTHING HAPPENED. The football passed into his son's hands and the actual photo he took was one of a cheerleader's pom-pom. Bob missed the touchdown too. He resisted an insane urge to slam the camera to the ground and jump on it.

This was his first digital camera, and Bob had just experienced an unpleasant surprise. He had used film cameras all his life, but when his Yashica went into the shop a friend loaned him a digital camera. He naively decided to take some action shots and discovered the most maddening "feature" of digital cameras the shutter delay.

MADDENING AND FRUSTRATING

Articles on this subject have attributed shutter delay to:

1. The camera's focus system

2. The time it takes the camera to digitally process the image

3. Reaction time of the photographer

Numbers one and three are lag times that most people using digital cameras are accustomed to. Most have used a film camera and know it needs a few milliseconds to focus.

The no-brainer solution is to reduce the aperture of the lens to increase depth of field, or aim the camera at the object you wish to be in focus and depress the shutter button half way in order to "tell" the camera what to focus on, then move the camera to center the image and depress it the rest of the way.

As far as human reaction time, well, it hasn't really changed much for users of film cameras, and people experienced in taking action shots usually get what they want.

So let's look at number 2, the time it takes to process the picture.

TIME TO DO THE PROCESSING

Processing the picture (so the camera can be ready for the next one) comes in several steps to move it from the image sensor to flash card storage:

1. Color corrections. The camera has to examine each and every Charge Couple Device (CCD) element on the photo sensor. It adds green, blue, and red to achieve the right color balance. For a 3 mega pixel camera, the processor has to make 9 million calculations.

2. Sharpening. This boosts the contrast by detecting and sharpening edges.

3. Compression. This process converts the 12 to 14 bits of each CCD sensor to 16 bits by "padding" the information and compressing it to 8 bits. This compresses the file size to 9 megabytes.

These steps require a tremendous amount of computational time. No wonder Bob missed his shot!

CATCHING THE ACTION

There are two ways of capturing action:

1. The "consecutive mode". If the camera has this mode, you can take a series of rapid shots moving through the event. This requires a camera with a large buffer" to hold photos for processing.

2. Anticipating shots by depressing and holding down the shutter release prior to the event. This requires an ability to predict the future, something most of us don't possess.

THE FUTURE OF FASTER SHOOTING

Obviously this would all be simplified if micro processing were faster. Even with large buffers, the speed in which data is transmitted to the processor is prohibited by the rate at which data is conveyed from the CCD. Micro processing speed is the next bottleneck.

The Variety of Roles Fulfilled by LED Lighting Devices

2007-11-25T21:15:00.001-08:00

At present, LEDs are extensively used in many different branches of the industry, taking many different forms and fulfilling a wide range of roles. Miniature LED devices are incorporated in thousands of products, including computer components, VCR, DVD, Stereo, Audio and Video equipments, gaming devices, security equipments, mobile phones, digital cameras, medical instruments, encoders, optical switches, fiber optic communication devices, etc.

While miniature LEDs play a set of crucial roles when they are integrated into small-sized technological products, larger scale LEDs can be successfully used as sources of illumination. LED lighting devices have proved to be the best alternative to traditional light sources (particularly incandescent and fluorescent light devices) and have already replaced such illuminating devices in many segments of the industry. LED lighting devices are nowadays commonly used for emergency / police vehicle lighting, traffic and rail lighting, accent lighting pathways, marker lights, emergency lighting exit signs, architectural lighting and signage channel letters, etc.

LED lighting devices have evolved considerably over the last few years and nowadays offer a wide range of benefits (energy efficiency, impressively long life span, durability, wide range of colors, no UV emissions, flexible design, silent operation, low-voltage power supply, easy to maintain) that render them superior to traditional, obsolete sources of light. Thanks to their advantages, LED lighting devices have become very popular and at present they are in great demand, being produced for both industrial and private, household use. Although LED illuminating sources such as LED bulbs, LED pods and LED tubes are already extremely reliable, economical, safe and durable, scientists claim that future designs will be substantially more efficient and a lot more affordable, incorporating high tech, innovative materials.

The great features of LED lighting devices (especially the wide range of colors and the economical character of LEDs) have caught the attention of many advertising companies and agencies that have rapidly started to use various designs for commercial purposes. Thus, LED bulbs, LED tubes, LED pods and various other LED lighting devices are nowadays included in most advertising panels and commercial signs, producing a multitude of vivid, bright colors. In addition, through inventive, imaginative combinations of colored LEDs, breathtaking color-changing effects can be produced by dynamically activating various arrays of LED lighting devices.

Some existing fixtures utilizing variable-intensity LEDs can produce more than 16 million colors, generating remarkable effects such as color washing, cross fading, random color changing, strobing and variable strobing. Such fixtures are easy to install and can be easily controlled via a PC or digital device. Multicolor LEDs can be used for lighting signage, decorative interiors, art exhibition interiors, simple and complex architectural structures, or the interior of different entertainment venues (clubs, discos, etc).

Both simple and complex LED lighting devices nowadays fulfill many different roles inside public and private institutions, industrial establishments, art and entertainment venues or simply private residences. While more complex LED lighting devices are more expensive, simple LED lighting devices such as LED bulbs, LED pods, LED displays and LED tubes have become increasingly more affordable. Such products come with long-term warranty certificates and can be purchased from a wide variety of offline and online specialized stores.

How does a digital camera combined auto focus work

2007-11-25T21:15:00.000-08:00

Objects in good focus in a digital photo is a very basic requirement for high quality photography. There are two different ways to focus on such objects: manual or automatic. There are a few automatic focus methods combined auto focus systems use more than one such method.

High quality sharp and crisp digital photos are a result of many optical parameters that need to be set right. One of the most important optical parameters is focus. When objects in a digital photo are out of focus they look blurry and are missing details and clarity. When objects are in focus they look sharp and crisp.

While the focus can be manually set by the photographer in most cases using the digital cameras automatic focus feature is much easier and faster. There are many different algorithms and methods that digital cameras use in order to automatically determine the right focus for a specific scenario. Such algorithms include passive and active auto focus. One type of combined automatic focus system uses these two algorithms to delivery superior automatic focus.

Combined passive and active auto focus

Active auto focus systems use distance sensors that measure the distance from the camera to the objects in the scene. Usually the camera measures the distance to the object or objects around the center of the photo. By knowing that distance the camera can then set the camera lenses to achieve good focus. One of active auto focus biggest advantages is that it can work in complete darkness. On the other hand active focus can fail in problematic scenarios such as when objects emit certain energies (like infrared) are photographed or when surfaces in the scene absorb the energy used to measure the distance.

Passive auto focus systems use software that runs on the digital camera built-in computer. The camera executes such image processing algorithms to determine a Focus Level number. The exact way in which such a number is calculated is out of the scope of this article. Suffice is to say that the camera uses some image processing algorithms with which it can calculate how good the focus is. Using these algorithms the camera can find the best focus for the scene. In some scenes the passive auto focus is limited or not functional at all. It does not work well in poor lighting conditions and does not work at all in dark scenes. It is also hard to focus on low contrast objects such as walls or solid surfaces.

Cameras that are equipped with combined auto focus systems pick the right system for the specific scene or cross check by using both systems at the same time. The photographer can also manually decide to use one of the two options. For example when shooting blue skies the camera can try to use the active system and measure the distance. Since the distance is infinite the camera can set the focus and skip the passive focus. In other cases when the distance is not infinite the camera can use the active system to put the lens in approximately the right position and then use the passive system for fine tuning. In dark scenarios the camera can opt to use the active system since the passive system will not work.

Vitamin Supplements for Macular Degeneration Prevent Visual Impairment

2007-11-25T18:22:00.000-08:00

Macular degeneration affects central vision, and some sufferers can no longer read books, write out checks, find phone numbers in a directory, watch television, or see the facial expressions of their loved ones. Simple tasks become impossible and frustration is common. Patients may feel alone because no one they know can relate to macular degenerations devastating effects. Not even a new prescription for glasses can restore the individuals poor eyesight. Many age-related macular degeneration patients fear that they will go to sleep and wake up to nothing but complete darkness.

What Is Macular Degeneration?
Macular degeneration is a debilitating eye disease affecting the elderly. Within the eye is the macula, an area that allows people to see fine details and colors. Macular degeneration prevents the macula from properly functioning and the vision becomes blurred. The most distinguishing aspect of this eye disease is that round spots cover the sufferers field of vision so that it is difficult to see things that are straight ahead. Fine details are impossible to see, but the persons peripheral vision is unchanged.

There are two types of age-related macular degeneration: dry and wet. Dry age-related macular degeneration is the result of fatty tissues called drusen building up beneath the retina. Wet macular degeneration is caused by abnormal blood vessels forming in the eye. Up to 90 percent of people diagnosed with macular degeneration have the dry form.

Ways to Prevent Macular Degeneration
Doctors say that there is no way to undo the harm that this eye disease has caused to the macula, but there are a few things that may lower your risks. These include quitting smoking, losing weight, eating a healthy diet, and taking a vitamin supplement for macular degeneration. Also, if you have a history of macular degeneration in your family, you are at a higher risk for developing the disease. You will need to see an eye specialist frequently for preventative care.

Take Your Vitamins
Doctors agree that nothing will reverse the damage caused by age-related macular degeneration, but studies have revealed interesting data in regards to this eye disease. Yellow and green vegetables help prevent age-related macular degeneration. Vegetables like squash, corn, broccoli, and spinach contain a variety of nutrients and antioxidants including lutein and zeaxanthin, two carotenoids. These vitamins and minerals may actually prevent macular degeneration in some people.

Doctors suggest that people choose a vitamin supplement for macular degeneration like VisiVite i-Defense Gold Formula that contains lutein, zeaxanthin, zinc, vitamin C, vitamin E, and beta-carotene. In fact, some retina specialists believe that this combination of vitamins and minerals are of benefit to people who are already suffering from macular degeneration in one eye. VisiVite i-Defense Gold Formula may actually slow the drusen forming in the macula and prevent the eye disease from forming in the other eye.

Keep Those Eye Doctor Appointments
One important aspect of senior eye health is to see your eye doctor often. You may already have age-related macular degeneration, but not be exhibiting symptoms. A retina specialist can determine if you have any eye diseases during an exam when your eyes are fully dilated.

Expect to have a dilated eye exam every few years or more often if you already have an eye disease. You may also need more frequent eye exams if you are overweight, are a smoker, or have a history of age-related macular degeneration in your family. All of these factors contribute to a higher incidence of this eye disease.

Learn to Adapt with Low Vision Aids
Being diagnosed with age-related macular degeneration can be quite frightening. The important thing is to ask your retina specialist the right questions so that you know what to expect and how to properly cope with this eye disease. Your eye doctor can direct you on some important things that may help you manage your condition.

For instance, you might invest in some special lighting that can prevent glare. Optical devices and magnifiers are available for you to see things better close up, but you might have to shop around to find the best one to suit your individual needs. Large print books may enable you to continue with a cherished pastime reading! Reading machines have given many people with macular degeneration the ability to cope with this eye disease by reading aloud information to users.

Final Thoughts
If you are diagnosed with a retinal disease like macular degeneration, it is very important that you realize you are not alone. You dont need to suffer in silence. Your eye doctor may have suggestions to help you adapt to the issues that age-related macular degeneration causes. Scientific evidence has shown that everyone with this disease should take a vitamin supplement for macular degeneration like VisiVite i-Defense Gold Formula to try and prevent your blurred vision from worsening and possibly improve vision. Also, there are many different low vision aids, magnifiers and optical devices, and other resources available for the visually impaired. Please remember that it is important that you see your retina specialist often, especially if your eyesight is worsening or if you suspect a problem.

Lasik Flap Dilemmas

2007-11-25T18:21:00.001-08:00

There comes a time in every laser eye surgical procedure when leaving the battlefield is the best of two (or more) evils. When is it best to reposition the flap, abandon the procedure and possibly attempt the LASIK procedure at a later time?
Obtaining adequate suction to certain globes is occasionally an elusive target. This includes small hyperopic eyes, flat or small diameter corneas, narrow palpebral fissures If the level of myopia permits, one has to remember that PRK is always an available option and patients must be made aware of this alternative and be consented for it prior to the procedure. A surgeon might be tempted to extend an incomplete flap with a crescent blade or similar instrument . This might lead to an uneven bed and scarring. The closer the hinge to the visual axis the riskier this maneuver will be. If the bed is large enough (not more than 0.5 mm of unexposed stroma at the hinge) laser treatment may be applied (with adequate protection to the underside of the flap).
A thin flap with an underlying shiny bed probably indicated an uncut underlying Bowmans layer. It is not clear if performing laser in this situation has similar or higher risk of haze formation as PRK. Until more is known about this issue, it is probably safest to reposition the flap and abort the procedure especially in high levels of correction. An irregular flap indicates an irregular stromal bed and is best allowed to heal back in position rather than risk inducing irregular astigmatism.
If a buttonhole occurs, immediate laser ablation of a central epithelial island by scraping or by the laser was reported to lead to uneven ablation and loss of BCVA.
The Free Cap
A free cap results from unintended complete dissection of the corneal flap by the microkeratome head. If the cap is trapped in the keratome head, it should be gently retrieved, stretched and kept in a dessication chamber if the diameter of the exposed stroma allows laser ablation. A small cap (i.e smaller than the optical zone) should prompt the surgeon to replace it in position and avoid the laser ablation. If the cap cannot be recovered, the epithelium will grow centrally as after other superficial keratectomy procedures and may result in a significant hyperopic shift.
Intraoperative factors leading to a free cap are the same as those leading to a thin or perforated flap, a poor blade to cornea coupling. This is especially true for flatter corneas which are more prone to a smaller cap. Other maneuvers such as malpositioning and/or misadjusting of the flap thickness foot-plate during assembly of certain microkeratomes can lead to a free cap.
In certain instances, the microkeratome can jam preventing head reversal. This might prompt the surgeon to release the suction thus lifting the instrument with an incarcerated flap resulting in a free cap.
Placing corneal marks with gentian violet is time well spent prior to cutting a corneal flap. When recovered, a cap can be repositioned using the preplaced marks to allow proper orientation. A bandage contact lens is usually helpful to tamponade the cap and prevent slippage upon lid contact. Suturing is rarely necessary.
If the cap is lost, the corneal epithelium is allowed to heal as in PRK with a more profound central applanation effect. Laser treatment is deferred until refractive stability is achieved.

Hair Removal - Painless and Permanent Hair Removal

2007-11-25T18:21:00.000-08:00

Hair removal is a vague term that has only recently been accurately defined. Temporary hair reduction is defined as a delay in hair growth, which usually lasts 1-3 months, consistent with the induction of telogen. Permanent hair reduction refers to a significant reduction in the number of terminal hairs after a given treatment, which is stable for a period of time longer than the complete growth cycle of hair follicles at the given body site.

Demand for a rapid, noninvasive method for hair removal has resulted in the introduction of various light sources for hair removal. Light source of hair removal commonly focuses on ruby, alexandrite, diode, and Nd:YAG lasers and intense pulsed light sources. These devices are designed to target either an endogenous chromophore (melanin) or an exogenous chromophore (carbon suspension, photosensitizer, and exogenous dye). Laser hair removal is one of the most recent systems of hair removal that has been introduced. Today, a large number of specific laser systems are available in the market, which makes the customer a bit apprehensive about their attributes, selection, treatment protocols and effects. Laser hair removal is one of the light sources of hair removal. Hair follicles are destroyed by light in a number of ways such as thermal, photomechanical or photochemical mechanism with generation of toxic mediators like singlet oxygen or free radicals.

Thermal mechanism for hair removal has recently been introduced to induce selective damage to hair follicles. Based on the principles of selective photothermolysis, this principle predicts that selective thermal damage of a pigmented target structure will result when sufficient quantity of light at a given wavelength is absorbed by the target in a time equal to or less than the thermal relaxation time of the target.

Melanin is the natural chromophore for targeting hair follicles in the visible to near-infrared region, Lasers or light sources that operate in the red or near-infrared wavelength region lie in an optical window of the spectrum in which selective absorption by melanin is combined with deep penetration into the dermis. Therefore, deep and selective heating of the hair shaft, the hair follicle epithelium, and the heavily pigmented matrix is possible in the 600nm to 1100nm region. However, melanin in the epidermis presents a competing site for absorption. Selective cooling of the epidermis has been shown to minimize epidermal injury.

Photomechanical destruction of hair has been attempted with very short nanosecond pulses. It has been done by the help of Q-switched 1064-nm Nd:YAG lasers, with and without carbon suspension. Short pulses are used to target hair follicles resulting in rapid heating of the chromophore (melanin). It leads to photo acoustic shock waves that cause focal photomechanical disruption of the melanocytes but not complete follicular disruption. Therefore, the Q-switched Nd:YAG lasers are not likely to produce long-term hair removal.

A distinction needs to be made between permanent and complete hair loss. Immediately after laser treatment, the hair shaft shows fragmentation with focal rupture into the follicular epithelium and thermal damage to the surrounding follicular epithelium. The extent of thermal damage is dependent on the pulse width but retains confinement on the spatial scale of the follicle itself. Histological changes are almost guaranteed in the person undergoing laser hair removal. However, such form of hair removal should be carried out under the supervision of a qualified dermatologist as it involves considerable degree of expertise.

Blu-Ray, too Expensive? I beg to differ

2007-11-23T22:29:00.001-08:00

Blu-Ray is the name of the most recent technological development for media storage. It is a totally new way of burning data into optical media discs, which elevates the entire playing field to a much higher level. The members of the Blu-Ray Disc Association (BDA), a group of the worlds leading consumer electronics, personal computer, and media manufacturers, developed blu-Ray jointly. As of Sept. 2006, the BDA consisted of 172 members and contributing companies and is lead by its board of directors consisting of Apple, Dell, Hewlett-Packard, Hitachi, LG Electronics, Mitsubishi Electric, Matsushita Electric, Pioneer, Philips Electronics, Samsung Electronics, Sharp, Sony, Sun Microsystems, TDK, Thomson, Twentieth Century Fox, Disney and Warner Bros. This technology was developed to enable recording, writing, rewriting, and playback of the highly popular and much publicized High Definition videos a.k.a. HD as well as an alternative for storing large amounts of data. Since the launching of the Blu-Ray technology in 2006, a lot of animosity and skepticism has already been generated by production houses, competitors, and even the general public towards it. One of the issues, of course like any other new technology, was its price and the cost of actually using, implementing or selling products using the new format. This article was written specifically to tackle this issue.

Of course, like any new upcoming and promising technologies, major companies as well as some minor ones who are somewhat dependent on this industry have already joined the bandwagon in promoting and implementing the use of this technology. In fact, companies like LG, Philips, Samsung, Sony, and Pioneer have already released their own 1st generation Blu-Ray compatible players. These players range from as high as $1500 for the Pioneer BDP-HD1 to as low as $499 for the Sonys PS3 gaming console. Companies like Benq, HP, LG, Lite-On, Sony, Samsung, Plexor, and others are producing blu-Ray disk writers and re-writers. Writers and re-writers are being sold within a price range of $600 to $1600. Last but not the least, companies like TDK, Panasonic, Sony, Verbatim, Imation, Memorex, Philips, and Fuji have already started selling Blu-Ray disks. They range from $18-$20 (SL) and $43-$48 (DL) each for BD-R and $24-$30 (SL) to $58-$60 (DL) each for BD-RE. Generally, Blu-Ray products like the players, writers, and discs have higher upfront investment cost compared to traditional SL DVD or the HD-DVD. We should expect companies to drop their prices significantly once the technology enters the mainstream. Like any other product, which eventually becomes a commodity, pressures from the laws of competition and economics of scale will sooner or later take its toll.

An indication of this is that even though Blu-Ray discs relatively cost higher to make, its per GB value is higher. For example, while the manufacturing cost of a single layered DVD is comparable to a single layered Blu-Ray Disc, its per GB value is not. Again, for comparison purposes, a 4.7 GB DVD costs around 1 dollar to produce, its per GB is then valued at 21 cents. A Blu-Ray disc costs $1.50 to make, then its per GB is still valued at a still much lower 6 cents. What am I trying to point out, you might ask. It is that even though Blu-Ray discs may have a higher upfront price tag, it is actually cheaper when you take the value you of what your actually getting into consideration. Its efficiency increases its productivity value and in return, giving more value to your money. So now, with that said, who says Blu-Ray technology is expensive?

Taking Portrait Photos with Blurry Background and Understanding Depth of Field

2007-11-23T22:29:00.000-08:00

We have all seen beautiful photos where the object is perfectly focused while the background is blurred. Such a photo can be very dramatic and might seem to be hard to shoot. In this article we will give you a few tips on how to shoot blurry background photos that will impress your friends and family. You will also understand what Depth of Field is and how to control it.

Depth of field (also known as DOF for short) is the most important thing to understand before shooting a blurry background photo. Depth of field is defined as the range in which the photo is in focus. For example an infinite depth of field means that the photo will be in focus from a certain distance from the camera and up to infinity. When taking a blurry photo the goal is to set the depth of field just around the object. In this way the object is in focus while the background behind it is not.

How do you control the depth of field? After all there is no depth of field menu in the camera (wouldnt that be nice). Depth of field is an optical figure that is influenced by a few factors:

The distance of the object from the camera: This is obvious to understand when taken to the extreme. Shooting an object 10 feet from the camera will result in a smaller depth of field than shooting an object 100 feet from the camera. Obviously shooting an object which for all practical purpose is infinite distance from the camera will result in the camera focused on infinity and the depth of field being infinite too..

The aperture: The wider the aperture (f number decreases) the smaller the depth of field and vice versa: the narrower the aperture (f number increases) the greater the depth of field. Just remember that the depth of field changes along with the f number: when the f number increases and depth of field increases and vice versa. Unfortunately you can not just change the aperture as you wish. Changing the aperture results in a need to change the shutter speed (either manually or the camera can most likely do that for you automatically). The wider the aperture the more light that penetrates the lens and the faster the shutter speed needs to be so there is a limit to how wide you can set the aperture to.

The focal length of the lens: The shorter the focal length the greater the depth of field and vice versa the longer the focal length the smaller the depth of field. For example if you use normal lenses at somewhere around 50mm your depth of field will be much greater than if you use zoom lenses at 200mm. With long focal length the depth of field can be extremely small. For that reason zoom lenses are a good choice in order to shoot a good blurry photo that is practically focused only on the object.

After understanding the theory it is best to go to the field an experiment. You will get a sense of how your photo will look like and how blurry the background will be after playing with different lenses, different apertures and different distances from your object. If you own zoom lenses start with taking photos of a relatively close object while using your zoom lenses. You will find out that it is extremely easy to get a blurry background photo using this method even without setting the aperture. Once you feel comfortable with that setup start changing the aperture and also change to your normal 18mm-55mm or similar lenses.

Most cameras allow to manually change the aperture by putting the camera in A mode while you are changing the aperture the camera will automatically set the shutter speed accordingly. Some cameras allow you to manually set both aperture and shutter speed.

In conclusion shooting dramatic blurry background photos is easy with some minimal understanding of depth of field and some experimenting.

A Buyers Guide to Film Scanners

2007-11-23T22:28:00.000-08:00

Film scanners are made for the sole and express purpose of scanning film directly into your computer. Unlike their flatbed counterparts, which may be able to handle media of various sizes and thicknesses and can even scan film if a transparency adapter is installed, film scanners scan only one thing: film. But because the image to be scanned is taken directly from the original material - from the film, and not from a print - film scanners allow more direct control over image elements such as cropping and aspect ratio. In addition, film has more detail and dynamic range compared to prints - which invariably lose tonal range and color data during the printmaking process. These are real concerns to photographers and graphic artists, who rely on original slides and film - and film scanners - to ensure the integrity of scanned images in professional and commercial applications. So, if your work relies on scanning negatives, slides, and other types of film, a film scanner is the right choice for you. This buying guide tackles some of the more important things that you need to know when looking for a film scanner.

Style and Type Some flatbed scanners include either an external or built-in transparency adapter that is used to scan film. Other flatbeds are of a dual-bed design; i.e., with one bed - the glass flatbed part of the scanner -for scanning prints; and another bed - a transparency bay that looks like a pull-out drawer - for scanning film. If you intend to scan only the occasional slide or stray piece of film, and don't mind the lower resolution as well, a flatbed scanner that can accommodate film may well serve your purpose. Be aware, however, that the resulting film scans will not be suitable for commercial or professional use. To obtain the best results, nothing less than a dedicated film scanner will do.

Bit Depth

A scanner's bit depth determines the number of bits captured per pixel, which is related to the number of possible colors. The higher the bit depth is, the greater the number of colors that can be shown. Bit depth for film scanners on the market today can be 30-bits, 36-bits, 42-bits, or 48-bits. Always aim for higher bit depth when possible, as this allows the scanner to work with and retain a greater amount of color information. A 48-bit scanner, for instance, produces 65,536 levels or shades of color per R,G,B (red, green, blue) channel, resulting in a mind-blowing possible combination of about 250 trillion colors. In contrast, a 36-bit scanner produces 4,096 levels of information, or a paltry 68.7 billion colors.

Resolution

For scanners, the optical, or "true", resolution is what matters, as this is the actual number of pixels being read by the scanner's optics. Film scanners have much higher resolution figures compared to flatbeds, with optical resolution in film scanners ranging from 2700 dpi to 5400 dpi, and 4000 dpi being the most common. The high resolution in film scanners allows you to enlarge small images, creating enough pixels in the process to print in full-page size.

An Overview of Document Management System

2007-11-21T23:29:00.001-08:00

Documents are a part of any office life and document management itself can be a tedious job. Usually when one thinks of a document management system, the first impression that comes to the mind first is that of an office without any paperwork. However, a document management system doesn't promise to make your office paper free. Instead it manages the documents in a particular way that makes the documents easily accessible, according to personal convenience. The information is stored in the desired form of media and therefore, refrains from wasting any additional time and space. The computer is the obviously device of choice when using the document management system.

Document management system softwares are widely available all over the world. Some of the terms to be familiar with which directly pertain to the document management system include the following:

Electronic document capture: Scanning, image conversions as well as text recognition come in this category. Paper media here, is simply converted into soft copies. By this method, both accessibility as well as cost effectiveness of a document improves dramatically. This also works when distributing documents as soft copies can be sent to people swiftly and also economically.

Optical character recognition: Optical character recognition actively comprehends characters printed on a physical media like for example on a normal paper.

Electronic document management system: This is particularly effective for a huge collection of electronically created documents. The electronic document management system would help in locating and displaying correctly any document that is required. This can also be used to maintain summary of documents and also different versions of the source document.

Electronic record management system: There are several concerns where there is specific need for records to be managed in a particularly ordered way. Examples include pay rolls and patient reports. The system manages the documents effectively by making it very easily accessible.

Web content management: This system specifically manages websites in an orderly fashion. There are several Web documents which need to be stored and published in any website and requires several permissions. Such needs are taken care of by this system.

Work flow management: required documents need to be kept within the reach of the concerned person at all times. This is managed by the Work flow system which is a very effective tool for document management.

Knowledge management: any relevant information needs to be communicated to the concerned person easily. This is particularly important with companies who wish to bridge any existing communication gap. FAQ are a good example of knowledge management.

These are the different terms and features that make up the document management system. Depending on these explanations, one may choose the management system which addresses an individual business requirement the best. You can later search and implement the chosen document management system in your business to ensure maximum productivity.

Understand Multiple Sclerosis To Fight It

2007-11-21T23:29:00.000-08:00

Most people do not realize how wide-spread the affliction of multiple sclerosis is in todays world. It affects tens of thousands of people, but it is one of those diseases where a very mild form of it could almost go unnoticed by the general public, and allow the patient to live a pretty normal day to day life. But for others, the effects of multiple sclerosis can be harsh.

Multiple sclerosis is generally considered to be a disease of the nervous system. With most patients, MS gets worse over time, although that time can be anywhere from a few weeks to several years, since the rate of degradation differs from person to person. The most obvious effect is the loss of motor controls within the central nervous system, starting with a loss of eeling and a loss of control over normal movements and speaking.

From a medical standpoint, MS affects the bodys central nervous system and breaks down the signals that go to the brain. This involves the threat to the different nerves and nerves sensors or fibers, also involving a threat to the brain, spinal cord, as well as in many patients, the optical nerve. What happens is that multiple sclerosis damages the enzymes and proteins that provide a defense or safeguard to those nerve fibers. This protective substance is known as myelin, where the primary purpose of myelin is to aid in the communications between the various nerve cells. Once the myelin safeguard is damaged or begins to break down, this causes a breakdown in the communications between the various nerve centers and their coordination.

Multiple Sclerosis, as various studies have indicated, seems to primarily be hereditary. Medical research has shown that the children of parents where either one of the parents has been diagnosed with MS are very likely to be afflicted with it. Certain hormones, particularly hormones associated with sex like progesterone and estrogen have proven to weaken the immune system and have the potential to cause MS.

The symptoms of multiple sclerosis are not readily evident unless you are watching for them. Since MS affects the central nervous system, the first indications of MS would be a lack of balance or tremors. Such symptoms should not be ignored if they persist beyond a few hours, and should be checked as soon as possible with your doctor.

Although it may sound trite, the best preventive measure you can take against multiple sclerosis is ensuring that you have a very rich and balanced diet. Your diet plays a significant role in almost anything you do, and the prevention of MS is certainly among those things. A balanced diet of the right foods will strengthen the immune system and help it fight against the breakdown of the myelin proteins.

Once you have been diagnosed with MS, there are many things that can be prescribed for you. Your doctor will undoubtedly recommend a balanced diet to keep your immune system and the nervous system safeguards as healthy as possible. The most important piece, however, is to get an accurate diagnosis as quickly as possible so that measures can be taken to fight it quickly.

The PowerShot G7 Digital Camera by Canon

2007-11-19T18:11:00.000-08:00

The newest camera Canon has put out for the advanced users, the Power Shot G7, had many serious photography aficionados snapping their fingers, anxiously awaiting its October 2006 debut. The 10 Megapixel digital camera is more than most casual users need but the consummate professional will find the Power Shot G7 great for snapping shots for enlargements and nearly unlimited cropping. A large 2.5 inch LCD monitor, complete with wide viewing will make on-camera screening much easier. The 6x optical zoom will make taking crisp, clear close-ups almost effortless.

Canons G series cameras all offer superior image quality but the G7 is one of their first to offer DIGIC III Image Processor with Face Detection Technology. Not only are images clearer and higher pixel count, but the processing and saving is twice as fast as previous technologies. Youd think such power would run your batteries dead in no time, but Canon addressed that as well by integrating low power consumption into the DIGIC III processor.

The Power Shot G7 6x zoom lens and compatibility with auxiliary lenses lets you snap shots in the middle of a soccer game without ever stepping on the playing field. You wont lose brightness or clarity as you zoom in and out of the game, either. Meticulously engineered lenses reduce and correct aberrations while Canon's new SR coating technology (used here for the first time in a digital camera) virtually eliminates ghosting.

There are so many shooting modes on the G7 youll be hard pressed to use them all.

Auto mode lets you focus on your subject and makes all the decisions for you. It's great for everyday pictures in normal light and motion situations. The P program is a more advanced Auto mode with the addition of advanced exposure compensation. The AV aperture priority mode allows you to isolate your subject or, in the alternative, to add clarity to your entire picture. The camera chooses shutter speed on the AV setting.

If you like more control of shutter speed, the TV shutter priority allows you to adjust shutter speed and possibly add blur while the camera chooses the appropriate aperture. Canons noise reduction will reduce the noise when on the TV setting. For ultimate control, choose the M, or Manual, setting. You choose the ISO speed, exposure and white balance. Once you find a setting you like on M, you can save it as a C, or Custom, setting.

Do you build panoramas or want to start? The Stitch Assist will help align the images in order efficiently and neatly.

Movie makers will love the Power Shot G7s options of shooting in XGA 15 fps (frames per second); VGA and QVGA - 30 fps for up to 1 hour or up to 4 gigabytes; QVGA (60 fps) for up to 60 seconds or QQVGA (15 fps) for up to 3 minutes.

If you like the blurred-background look of traditional portrait shots, choose the Portrait special scene mode. It will automatically focus on the subject while blurring the background. For sharpness from front to back, the Landscape scene mode will set a small aperture for a great landscape photo.

Why use Eyeglass Lenses?

2007-11-17T00:18:00.000-08:00

A necessary part of having a pair of eyeglasses is the lenses. Lenses are made from three basic materials: plastic, glass, and polycarbonate. Plastic, the widely used material for lenses and it is stain resistant and lightweight but limited to simply being scratched. Glass is as well used for lenses and is cut resistant but is heavy and breakable. Most everyday use lenses are created from high resin. Hard resin lenses are actually lightweight, offer good optical excellence, and are resistant to scratches. They could as well be further upgraded with color tints, UV - protectants, or photo chromic. Polycarbonate lenses are especially indented for high bang resistance and are perfect for occupational hazards, children, and for athletes. They offer the most excellent eye protection.

High Index Lenses allow broad prescription glasses to be thinner by compact the material. "Index of refraction" is a normal term that is used to explain the speed at which light travels during the material. A greater index results in thinner lenses. Technology has made it probable for both plastic and glass lenses, which have a huge index. High Index lenses are normally lightweight, look really thinner, and do not enlarge your eyes but come expensive.

Eyeglass Lenses Upgrade

Scratch protectant coating is a necessity for plastic or glass lenses. It is simple to scratch your lenses and its damage normally cannot be repaired, thus wasting a good pair of glasses. A scratch resistant coating would assist the lenses become more anti against most abrasions.

One of the causes of cataracts can be the bigger amount of ultra-violent light, which visit our eyes. A UV coating assists to lessen the amount of UV rays, which enter our eyes by jamming it through the lens. A UV coating is cheap and the end result of defensive our eyes are worth the price.

Polarized lenses are same as sunglasses in that they are tinted with a polarization filter and as well block vertical light from appearing stress on the eyes. They are high quality for outdoor activities where the sun would be glaring down on you. Make sure to ask your optometrist or optician on lenses and that type will be more advantages to your lifestyle and upgrades that are a necessity for you.

Electronic Document Management Systems

2007-11-13T00:30:00.001-08:00

An electronic document management system is a computer-based system whereby software tools are used to capture, process, index, store, retrieve, distribute and dispose of the documents. The documents may be in the form of spreadsheets, word processing documents, multimedia files and the like. An electronic document management system includes the capturing of documents through scanning, bar coding and optical character recognition, maintaining workflow management by the control of an orderly flow of documents, and the distribution of documents across individuals and departments.

Many of the processes of document management systems are included in electronic document management software, which also allows documents to be captured and stored in the form of graphical images. The software can be run on a personal computer and networked using the companys existing network. It allows instant access to documents, enhances collaboration with respect to sharing information among departments and offices, and ensures security to files and records.

A user can create a document, attach graphical images and index the document along with the attachment, using the software. Any information on the document can later be accessed simultaneously by all users having a security clearance, irrespective of their geographical location. Subsequent changes and modifications made thereafter are also stored, along with the original document which the other users can view as a complete file. An electronic document management system ensures against misplacement or loss of files due to the provision of an online security system. Also, it makes disaster recovery easy because of the possibility of the external storage of information. In addition to this, the software provides control over the users who can access, view and forward any documents.

An electronic document management system is more cost-efficient than paper-based document management. It saves costs on office space, file cabinets, papers and personnel to maintain the files.

Electronic document management systems can be implemented in organizations where there are large volumes of documents that are difficult to manage and track because of their distant physical locations. It is beneficial to organizations which have to provide instant and multiple access to the information and keep track of all the modifications made by the users to the original documents during its lifecycle. An electronic document management system brings about the centralized management of documents and enables better and faster decisions due to improved workflow management.

Why should I care about my digital camera CCD sensor size?

2007-11-12T22:04:00.001-08:00

Everybody knows to check how many mega pixels their new camera has. Although more mega pixels does not necessarily mean better photos most people understand why mega pixels are important. One characteristic of digital cameras that many ignore is the sensor size.

Digital cameras capture digital photos. A digital photo is a collection of pixels. Each pixel has its color and intensity. When all these pixels are put together the result is an illusion of a photo. Pixels are captured by the camera using an electronic sensor known as a CCD. The CCD sensor is a silicon chip that is built of many tiny light sensors. When taking a photo each such tiny sensor measures the amount of light also known as intensity and some other attributes such as the color. Each such sensor results in one pixel and all the tiny sensors put together represent one digital photon.

This is very interesting to know but why should you care? The reason is that there is a relationship between the size of that CCD sensor and the number of mega pixels that it supports. This relationship is important and has practical consequences. It is intuitive that for the same CCD sensor size, the more mega pixels the smaller each CCD tiny sensor is. The same is true if the number of mega pixels is fixed: the bigger the CCD sensor the bigger each tiny sensor is. For each CCD sensor size and number of mega pixel we can calculate the pixel sensor size.

The pixel sensor size is important and influences the characteristic of the digital camera especially in marginal light scenarios. Your digital camera sensitivity to light is directly influenced by the pixel sensor size. The bigger the sensor size the more light it can accumulate in a certain period of time. The result is that bigger pixel sensor sizes allow for faster shutter speeds at lower light conditions. In addition bigger pixel sensor sizes result in less noise captured by each such sensor.

In practical terms if you take two digital cameras with the same number of mega pixels but different CCD sensor sizes - the camera with the larger CCD sensor size will be provide digital photos that are sharper and have less noise. It will also be able to take digital photos in scenes that are too dark for the other camera. In normal light scenes the higher light sensitivity allows more range for changing the aperture and shutter speed and more freedom with getting different focus depths.

Bigger CCD sensors are more expensive. There are many reasons for that one of them is the lower manufacturing yield. For that reason cheaper pocket cameras use smaller sensors than high end digital SLR cameras. CCD sensor size also influences other optical attributes of the camera for example the aperture needed in a specific scene changes as the CCD size changes. The depth of field is directly influenced by such aperture changes. To normalize optical figures many cameras manufacturers choose to normalize their optical attributes to the good old 35mm film (film can be seen as a sensor too, 35mm in size).

How To Shop For Digital Cameras

2007-11-11T17:38:00.001-08:00

There has been a technological revolution over the last twenty years. From the spread of the pc to the rise of CDs, DVDs and MRP3 players; how we approach and record our images of the world is changing. One of the most significant developments to have appeared on the market has been the digital camera. Almost everyone who owns a pc also owns a digital camera. The beauty of these is that you can view your picture as it will be and then decide whether to snap or not-once snapped you can see the picture again. Pictures taken with a digital camera can be uploaded to a computer and then printed out on the special paper that you can buy; alternatively you can put them on disc and take them to a professional processor.

The digital camera is uniquely different from what went before. Prior to the invention of the digital camera, even the most high tech cameras depended on mechanical and chemical processes. Digital cameras work differently because they have an inbuilt computer that records images electronically. Basically they are filmless cameras. When they first came out digital cameras were beyond most peoples budgets-as they have become more popular, the price has dropped to the point where they are as affordable and flexible as similarly priced film cameras. The amount of images you are able to store depends on the amount of memory you have-storage can be anything from 16mb to 256mb. The memory size also has an effect on the resolution of the pictures you are taking-memory cards are removable however, and can be replaced with something that has more storage capacity.

There are three main styles or shape of digital camera, the first is small enough to fit into a pocket, it is the most sort after style and also quite expensive. Next you have the standard size, which is bigger and able to do all the things that the point and shoot camera will do. This model is good value for money. Finally there is the digital SLR which produces the best photographs. It is an extremely flexible model and you can switch lenses with this one, but these enhanced features come with a corresponding price tag.

Other information you should be interested in when buying a digital camera is pixels-briefly put, pixels are the dots that go to make up a picture. These pixels are measured in thousands of such dots; called megapixels. The more megapixels you have the sharper your pictures will be and the bigger the price tag on the camera. If all you want to do is produce 4x6 photos and maybe email some images then a 4 megapixel camera should be adequate for your needs. You need to bear in mind however, that the quality of the images you produce depends on three things; the speed of your computer, the type of software that the camera works with, and the quality of your laser or inkjet printer.

The final thing that you might want to bear in mind is optical zoom-this lets you magnify what you are shooting and gives you more control over framing the shot. The one most recommended for flexibility is the 3x optical zoom, dont let vendors confuse you with digital zoom-it is not a viable consideration. With this information at your fingertips you should have no trouble in purchasing you first digital camera.

Basic Digital Photography: Taking Action Shots

2007-11-09T20:37:00.001-08:00

Personal photography has gone through a sort of mini evolution in the past 20 years as digital cameras have become popular. With the ability to take huge numbers of pictures, save them on computer, and share them over the internet, the cost of film and developing are no longer limiting factors. Although group photographs, portraits, celebrations, and vacations are still common images, personal photography now captures more impromptu and daily types of events. Photographs of fast moving action are more common as well as people are able to experiment to obtain the type of images they want without fear of "ruining" a shot that requires more skill to take. Capturing action can be challenging for a beginning photographer and requires quite a bit of practice to master. The following outlines a few pointers that can get the novice started off on the right foot.

1. When trying to obtain shots of action, the photographer can use one of two approaches:

Follow subjects with the camera as they wait for action to happen.

Focus the camera on a particular spot where action is anticipated and wait for it to happen. An example would be focusing on the basketball goal or 1st base. When using this method it is often best to observe through the Optical Viewfinder and keep both eyes open so that it is easy to anticipate shots as action approaches.

2. Reduce lag time and latency:

Shutter lag is the delay between the time the shutter button is pressed and the time when the camera actually takes the picture. During this lag time the camera is setting the exposure and focus. Shutter lag is particularly problematic when trying to capture action shots. One way of decreasing shutter lag is to press the shutter button halfway down, hold it, and then press the button down completely when ready to take the shot. This process allows the camera to perform some of the focusing function prior to taking the shot thereby reducing the shutter lag time.

Latency is the time it takes the digital camera to write/store images before the next shot can be taken. To reduce latency, a photographer should use flash cards with fast write times. In some instances, a lower resolution setting can be used for the shot so that the camera has less information to process and store, but this technique of reducing latency must be used carefully as image quality can be compromised.

3. Follow the action; this is known as "panning". Panning involves tracking the motion of the subject horizontally to capture the movement as it goes side to side. As the photographer moves in the same direction as the motion, a slow shutter speed is often used to allow the subject to be focused and the background to blur demonstrating the action that is occurring. Panning is not necessary for all action shots but is one method of demonstrating the movement while keeping the subject in focus. The process of panning involves the following:

Old Fashioned High Resolution Photo Camera

2007-11-07T20:07:00.001-08:00

Tired of trying to keep updated with the highest mega pixel resolution digital camera? Well even if one has tried to do that, most certainly he will soon find out that his few months old digital camera is outdated in terms of mega pixel resolution. Its an ever changing kind of product that has become very hard to keep updated, unless one is willing to spend more money by making purchases every six to twelve months.

If the main intention of purchasing a photo camera is enlarging the image, then mega pixel resolution indeed will become the main factor. In this case one might consider a different option, which will keep his product updated for years to come. Im talking about a used 4x5" film photo camera, together with a high resolution flat bed film scanner. All of this for less than one thousand US dollars. With all of this, one will get over 100 mega pixels in fine detailed film resolution and fine scanned digital images that can be enlarged up to 30x40" in size with professional quality. These 4x5" film cameras have done a remarkable job in general personal and commercial photography such as wedding, portraiture, product, documentary, advertising and landscape for nearly a hundred years.

Where to find 4x5" used film cameras? Since some of these cameras were mostly used in the past, until the 1960s, it should be no problem in finding them in American auction web sites. Anyway, a good used 4x5" camera with lens can be found for less than four hundred US dollars.

As for the flat bed film scanner, one can find brand new ones for less than five hundred US dollars. Just make sure the scanner is able to scan films.

Whenever purchasing a 4x5" film camera, one should look for the following features: folds into a compact box, flexible bellows, lenses that can be easily interchanged, accepts sheet film, ground glass focusing screen, easily handheld and optical viewfinder accessory.

As for the lenses, there are four main categories: 1 - general purposes; 2 - wide field (mostly used for close up work and landscape); 3 extreme wide angles lenses; 4 special effects lenses (telephoto). However, one might use a general purpose 127 or 152mm lens for most of his photograph sessions. In cases where it requires special lenses, such as architecture or macro photography, one will still find lots of them available in auction sites. Used lenses for 4x5 cameras made after world word II have excellent performances comparable to todays modern lenses.

Whenever making a purchase of a 4x5" camera make sure that: 1 - the bellows have no light leaks, 2 the lens shutter works accurate at all speeds; 4 the lens elements have no fungus and scratches of any kind; 4 the focus is working properly between the ground glass and the film.

The option of using a 4x5" film camera, together with a flat bed film scanner, for enlarging images with professional quality is viable and accessible. Cheaper than top digital cameras, the 4x5" film camera offers better image quality and will always be updated in the future, maintaining its original value.

For those who wishes the very most detailed image enlargement, one can always use the 8x10" film camera. Four times the physical film size of the 4x5", this option offers so much film resolution that it is considered by many as the ultimate step for photo image enlargement.

Sometimes analog products deliver better results that its digital counterparts. If you are doing the job of enlarging photo images, you should give it a try with a 4x5" camera. You might just surprise yourself.

Eric Freeman Biography and his Art work

2007-11-06T22:07:00.001-08:00

Eric Freeman was born on 1964 in Yonkers, New York and currently Lives and works in New York.Pulsating with an electrified glow, Eric Freemans paintings resonate disquiet energy, their minimal compositions dizzying in their defiance of space. Comprised of four diffused coloured bands set vertically against a black ground, Industrial Road reverberates with immaculate tension, its forms appearing to undulate in 3D perspective. Drawing comparison to abstract painters such as Ellsworth Kelly and Frank Stella, as well as sculptors such as Dan Flavin and James Turrell, Freemans work combines the illusory qualities of paint with the physicality of altered environment; his large scale canvases having the effect of magnetic fields, shifting the perception of centre of gravity.

Paying homage to artists such as Joseph Albers and Marc Rothko, Eric Freemans Red Inside Green re-devises the metaphysical qualities of abstract painting for a contemporary age. Using contrasting hues, Red Inside Green offers subtle deception through colour perspective, its geometric forms continuously bulging and receding in illusionary space. Seamlessly painted in oil, Freemans canvas possesses an artificial vivacity; its ethereal glow reminiscent of plasma screen technology, creating an electrifying aura that is both spiritual and synthetic.

Eric Freeman marshals fields of electric color and optical effects in the service of an abstracted landscape. Of the five vivid, oil-on-linen paintings included in this show of untitled works dated 2003, four are 8 feet square, and of those, three express the distinct horizon-centered orientation of a landscape with a central darkness disclosed as though from between thin, parted lips. The paintings' upper and lower halves seem symmetrical and appear to swell out horizontally from the support, expanding through sometimes hot, often acidic hues that resolve into thin bars of graduated color that bracket the upper and lower edges.

Conclusion :
Eric Freeman's diffuse paintings are not unlike the artist himself. Stand back and you see bands of hazy color. Get closer and you see their construction and feel the hand and compassion of the artist. But the paintings - and Freeman - never completely come into focus.

How to shoot sharp digital photos without a tripod

2007-11-05T23:00:00.001-08:00

Tripods are used when you need a steady platform to take a digital photo. In some scenarios not using a tripod will result in a blurry digital photo with its objects either blurred or simply out of focus. However there are times when you will find yourself in a situation that a tripod is needed but you do not have one with you to use. Here are some alternatives to using a tripod when one is not available.

Like film cameras digital cameras are also sensitive to movements and shakings while shooting a photo. If the digital camera moves while the shutter is open the result will be a soft or blurry photo. Usually camera movements are very small and in high shutter speeds the camera does not have an opportunity to move enough in order to distort the digital photo. However in some scenarios such as slow shutter speeds, low ambient light and macro or high zoom photos even the tiniest movement will result in a blurry digital photo.

As a general rule photos that are taken with slow shutter speeds or high zoom values should be taken using a steady platform. The best steady platform is a tripod but when a tripod is not available (for example when you travel and you do not want to carry a bulky and heavy tripod with you) there are some other methods and alternatives that you can use as a steady platform. Here are a few:

Lean the camera against a steady surface: you can use almost any surface that is steady in order to stabilize the digital camera. Such surfaces can be anything from a table, a wall, a bench or a light pole. Make sure that the surface is indeed stable by trying to shake it a bit with your hand. When taking the photo put the camera against that surface and apply some force (for example your weight) to make sure it does not move.

Place the camera on a horizontal surface: another option is to simply place the camera on a horizontal surface. The surface needs to be flat and stable. When you shoot the digital photo you should gently press the shutter button making sure that the camera does not move and then let go. Gravitation will make sure that the camera stays stable on the surface. The main problem with this method is that the camera might shake or bounce when the shutter button is pressed. To overcome this problem you can use two methods: delayed photo set the camera to timer mode using the shortest time for example 2 seconds. When you press the shutter button the camera will start counting and will have enough time to stabilize before the photo is actually taken. Remote control if you have a remote control use it to initiate the photo shooting instead of pressing the shutter button.

Image stabilizer enabled lenses: an expensive option that requires thinking ahead is the usage of lenses that include an image stabilizer. This technology can be implemented in a few methods for example using a floating optical element that compensates for movements or by using special software that controls the CCD sensor. Regardless of the technology such image stabilizers can effectively compensate for small camera movements and are commonly used by professional photographers taking high zoom photos.

Regardless of the method you use to stabilize your camera one thing to remember is that the more photos you take the higher the chances that one of them will be perfectly sharp and in focus. If the scenario is not easy to shoot and you are afraid that you might get blurry digital photos take your time a shoot a few photos using different stabilization methods and camera settings. You can later on browse through the photos and choose the best one.

London builders: how a small bathroom becomes a large bathroom. Part1.

2007-11-05T18:55:00.001-08:00

If you dont live in a customized house with a luxurious bathroom and a separate dressing room, you are most likely to wish your tiny bathroom were larger. While the owners of large bathrooms decide in what corner to arrange the swimming pool, owners of little bathrooms try to contrive how to fit into the area of 3 sq. m. everything plus the laundry washer.

Little bathroom makes some people feel more comfortable and practical. It is possible to take whatever you want from any shelf without moving, and some tall luckiest can even touch the ceiling. But others feel uncomfortable in little premises, being oppressed by them, they feel as if walls pressed on them.

Depending on the style of your house, your bathroom can fascinate by its simplicity or surprise by its elegancy, calm down with its comfort or hearten by its brilliance. But irrespective of the style that you created in this room, it will still remain a small premise. But apply a little magic of optical illusions - proper color and apt illumination, and room will be visually widened.

Sometimes in order to feel comfort, you dont need to add meters to the room. Use our prompts and make your small bathroom bigger.

Illusions of light. Light plays one of leading roles in the beautification of premises. It is necessary to think it over on primary stages of repair and straight away prepare places for lighting units.

Dissipated or reflected light multiplies the area. But it is desirable that finishing of the room was able to reflect light. Light colors reflect light, and dark ones absorb it. Glossy surfaces also reflect the light. Nowadays ceiling can also be covered by gloss there are hung and stretched ceilings. Such ceiling makes the bathroom one and a half times higher, and the mirror-faced ceiling increases its height by two times. But fans of mirrors are to remember that the mistress of the house may find it a bit straining to wipe the brilliance of this splendour at least once a week.

If to direct the bright light at the ceiling, it will seem higher. And on the contrary, a low or massive luster will decrease the height of the premise. The luster light, directed downward, will also diminish the height of the premise. When the ceiling is in the shadow, the height of the premise is diminished too. Try to avoid dark corners. They narrow the area optically.

For little rooms it will be better to use build-in light units or hidden illumination. Setting of such illumination over the perimeter of the room will create the atmosphere of airiness and lightness.

Illusions of colour. Select light tones for walls and ceiling. They visually widen the area. But try to combine light colours. Because a one-coloured room will surely bring you no pleasure. The floor is to have rich colour to increasing the height of the premise: it can be red, blue, yellow and tints of these colours.

Colours that visually widen the area are: white, beige-orange, yellow, light blue, blue, dark blue-green. Dark colors diminish the room, they are black, umber, yellow-red, orange-red.

High Speed Internet With T3 Internet Service

2007-11-04T22:26:00.001-08:00

T3 lines are used mainly by Internet Service Providers (ISPs) who connect their customers to the Internet Local Area network and Wide Area Network; it is similar in technology to a T1.

T3 Internet connection or Trunk Level 3 is capable of transmitting data up to 44.7 million bits per second (mbps) through an extremely high bandwidth equivalent to about 672 regular voice-grade phone lines. T3 connection, by copper, is similar in technology to a T1, but it has greater bandwidth through which it can transfer data to and from Internet at a higher speed. A full T3 or DS3 line is equivalent to 28 T1 lines in terms of data transfer per unit time but it has to be customized accordingly to gain optimal benefit. A T3 circuit can also be by fiber and that is how most DS3 circuits are these days. A fractional T3 Internet service is ideal for customers who need data transfer more than 6 mbps (ideally at 10 mbps or more) and less than the full 45 mbps of the T3 internet line. The reason for that is the local loop for the T3 circuit, is more costly and financially, it does not make sense to get a fractional DS3 for less than 6 mbps. A T3 line is used as a major networking pathway by companies that use lots of bandwidth, big business organizations, and universities with high-volume network data transfer, large corporations, and government organizations.

Like Trunk Level 1 Internet connection, T3 lines are often called DS3 lines (Digital Signal Level 3), which are made up of two components the primary or local loop and the port. Primary or Local T3 loops are more expensive than T1 loops because they allow more amounts of data transferred due to its larger bandwidth capacity. A T3 line comprises of 672 individual channels and each of them can carry 64 Kbps. T3 service is also termed Digital Transmission Level 3, because it can transmit any combination of data of audio and visual applications. In fact, a T3 circuit is a specific term that transmits data at 64 kbps in each of its 672 channels while DS3 is a generic term that encompasses circuits with the same bandwidth. Both T3 and DS3 lines have the potential to carry 672x 64 Kbps or 44.7 million bits per second (mbps).

A T1 line is used by small and medium-sized companies and it is capable of transmitting text files, graphics, sounds, and database instantly; whereas a T3 line is appropriate for big workforce where larger volumes of data can be transmitted including video and audio files. In case of the T1 service, it will take more time than a T3 connection in transferring audio and video files. Through ordinary residential modem or telephone line it is not possible to transmit both audio and visual data simultaneously. To send or receive any kind of large or constant audio-visual files in undistorted form, you have to rely on T3 Internet service, which provides reliable, uninterrupted, hassle free, and high-speed huge amount of data transfer.

T3 technology has two applications in wide use in corporate networking as Internet link and as a means of aggregating multiple T1 lines into one physical access point. The first application acts as a single channel between two points of Web server and the Internet. The second application is a canalized system, which works just like a combination of T1 lines. The third application, which is less common than the other two, is used to interface a T3 Internet directly to a far-off access controller. And this application helps to continue 672 simultaneous dial-up connections via one physical link. The problem with copper based point-to-point T3 lines is that it does not work with optical interfaces, unlike a fiber based T3/DS3 circuit.

Shaped Mouse Mats For Added Advertising Prominence

2007-10-31T02:24:00.001-07:00

Promotional mouse mats are a great way to advertise your business. Theyre a useful item with plenty of advertising space, so your advertising message is sure to get noticed, day after day. If youre planning a special product promotion or if youd just like to create a design thats a little bit out of the ordinary, shaped mouse mats are a great option.

Shaped printed mouse mats prices start at just 0.94 for a full four-color design, so they wont cost you much more than a standard square mouse mat. Ideasbynet offers a variety of standard shapes you can select from, but if you would like to design your own, there is virtually no limit to the shape variations you can choose. Just keep the usability of the mat in mind when deciding on a shapemake sure that the shape you choose allows for plenty of space in the middle of the mat, so that users have space to manipulate their mouse, and you have space to add your company name, contact details, and other important information you want to include.

Its also best to avoid shapes that leave you with narrow or pointed areas (such as a many-pointed star, for example). These will be unlikely to tear, as mouse mats tend to be quite durable, however they will be more difficult to package safely. After being used for a while they may even bend and cause the recipient to discard the mouse matand your advertisementin favor of a mat with a more practical shape.

When deciding on a shape, take into account the amount of information you will need to display on the mouse mat for maximum advertising effect. You will most likely need to include a company logo, a slogan, and contact information as a bare minimum. If your mouse mats are promoting a new service or product line, youll also want to include information about your promotion. Remember to try and keep your design as simple as possibleif your mouse mat is cluttered with too much information, your customers are less likely to bother reading it. Additionally, if you end up with that much text on your mat, it doesnt leave much room for a prominent logo and company name.

Choosing a shape also requires that you consider the theme of your business. If you own a pet store, for example, a dog or cat face is a fun option, and the pets identification tag can include your contact information. A sporting equipment store lends itself well to a round mouse mat, with any type of ball used as the basis for the design. When choosing colors, keep in mind that your mouse mats will need to appeal to a broad cross-section of peoplenot all your customers will share exactly the same tastes.

Once your design is created, Ideasbynet.com will create your printed mouse mats on a tough, durable surface that is suitable for optical, wireless, and traditional mice. Within fifteen days of approval of your project, your mats will be shipped to you, so you can start using your shaped mouse mats to create a big impression with your customers!

The Beauty of Dichroic Glass

2007-10-30T20:52:00.001-07:00

New advances in the development of materials are constantly affecting the fashion industry, for example new or evolved fibres lead to improved fire and crease resistance of fabrics. These developments often allow for the creation of ever more stunning and impressive designs and this is true of Dichroic glass and contemporary jewellery.

Dichroic coatings (pronounced di-crow-ic) are in fact no new technology, they were developed in Germany over 100 years ago and have since been used for applications ranging from the diagnosing of certain diseases to use in heat seeking missiles. Dichroic glass was originally developed for use in the U.S aerospace industry but today we see it in a much more artistic light as it revolutionises designer glass jewellery.

The process of creating Dichroic glass involves the accurate depositing of layers of quartz crystals and metal oxides such as titanium, silicon and magnesium on to clear glass. Dichroism is literally an optical effect that is observed in certain materials in which two different colours are seen when viewed from different directions. In Dichroic glass one colour is seen when light reflects off the crystalline surface and with a change in angle a second colour is viewed as the light passes through the glass. The additional process of fusing the glass together at high temperatures melts the glass and further alters its colour and character. Completed Dichroic glass therefore has a hidden depth of ever changing colour that is reminiscent of elements in nature such as dragonfly wings and peacock feathers.

Handmade Dichroic glass jewellery is an extremely skilled art form which, when done well achieves beautiful and stunning results. The design possibilities are limitless in all areas; colour, shape, pattern, texture etc and with a creative designer tremendously unique and interesting pieces can be produced. It is a contemporary medium for jewellery which can be adapted for both everyday wear and for striking special occasion pieces that dance in the light like diamonds but without the enormous price tags.

The best part about handmade Dichroic glass jewellery is that each item is individually crafted and so has its own unique quality and character for it is impossible to recreate the same piece twice.

Types Of Moton Capture Systems

2007-10-30T18:38:00.001-07:00

As motion capture technology developed, several uniquely different types of motion capture systems evolved. The types of motion capture input systems are: mechanical, magnetic, and optical.
Mechanical:
Performer wears a human-shaped set of straight metal pieces (like a very basic skeleton) that is hooked onto the performer's back; as the performer moves, this exoskeleton is forced to move as well and sensors in each joint feel the rotations. What is the apparatus? I t basically a large joystick. And this joystick is attaches to the body of the performer and moves according to the movement of the performer.

Advantage: no interference from light, well that removes the worry of wondering whether there will be a necessity for dim lighting , and from magnetic fields.

Disadvantage:
a)the technology has no awareness of ground, so please no aerobics no jumping, and moreover the data sometimes look like the performer was literally being swept of his/her feet.
b)equipment must be calibrated often
c)unless there is some other type of sensor in place, it does not know which way the performer's body is pointing, resulting in the possibility if the person doing the post production doesnt have the original video there is a great chance the character will end facing the wrong direction and creating many a red face.
d)absolute positions are not known but are calculated from the rotations

Optical:
Performer wears reflective dots that are followed by several cameras and the information is triangulated between them. Markers are either reflective, such as a system manufactured by Vicon or Motion Analysis, or infra-red emitting, many of which have been developed for musical applications (such as conducting). Developed primarily for sports injuries, analysis of athletic performance, games, animation, etc. New developments are allowing for real-time capture and work with animals.

Advantages:
a)performer feels free to move due to no cables connecting body to the equipment
b)larger volumes possible
c)more performers are possible
d)very clean, detailed data

Disadvantages:
a)It is prone to light interference
b)reflective dots can be blocked by performers or other structures, causing loss of data, or occlusion-this can be compensated for with software which estimates the position of a missing dot
c)rotations of body parts must be solved for and are not absolute
d)information has to be post-processed or 'tracked' before viewing so performer cannot see his or her image and so cannot be as creative or identify potential problems (a hand hitting a giant nose, for example)
e)higher cost than magnetic

Magnetic:
Performer wears an array of magnetic receivers which track location with respect to a static magnetic transmitter. Magnetic was used for the military, to track head movements of pilots. This type of motion capture is layered with animation from other input devices.

Canon IXUS 65 versus Canon IXUS 60

2007-10-30T01:10:00.001-07:00

On paper it is hard to set these two cameras apart. They both share the same 6MP CCD sensor, DIGIC II image processor and 16 shooting modes. Regarding the optics, the two Canon cameras are identical. Their optical zoom is 3X and the digital zoom is 4X. Some other common traits of the two devices include the TTL Auto-focus and the 9-point AiAF/1-point AF focusing method at the centre. Essentially, the two cameras are the same with two very important differences.

The first main difference between the two cameras is the screen. The screen of the Canon IXUS 65 is a 3 inch LCD. The IXUS 60 is fitted with a 2.5 inch screen (and so is the rest of the current Ixus range). That extra half inch can make a big difference especially if you wish to share your images with friends or you eyesight is not perfect and find it difficult to view images on smaller screens.

The second less obvious but very important difference is the body construction. The Ixus 60 has a metal body, while the Ixus 65 is made out of hard plastic. If you are able to treat your camera with care this should not make much difference. If on the other hand you tend to drop your camera often, or dont like using a protective case, the plastic body of the Ixus 65 may deteriorate quickly, so the Ixus 60 may provide a more rugged alternative.

The screen size and body material construction lead to the subtle difference in the dimensions of the two cameras. The Ixus 65s dimensions, namely 90.3 x 20.2 x 56.8 mm (W x D x H), slightly differ from the dimensions of the Ixus 60 (86.0 x 21.7 x 53.5 mm). As you can notice, the Ixus 65 is slightly wider and higher to accommodate the 3 inch LCD screen. As for their weight, the Ixus 65 weighs 140g, and the Ixus 60 weighs 145g. This small weight difference is due to the metal construction and is virtually unnoticeable.

The larger screen of the Ixus 65 comes at a financial cost. Its Australian recommended retail price is AU$529.00, which is $80 more than the Ixus 60 (priced at AU$449). In our opinion, unless you specifically need a larger screen, you would be best off buying the Ixus 60 and put the savings towards the purchase of a large memory card.

Large Format Color Scanners

2007-10-29T21:21:00.001-07:00

For almost all applications in which art or beauty is given primacy, the use of a color scanner is imperative. Digitalizing of portraits, indigenous textile designs, and large paintings call for the use of large format color scanners. The particular application in question may be best suited by color scanners of either flatbed-type or drum-type scanners. The choice of imaging technology between the traditional scanner using charge-coupled device (CCD) and the less expensive alternative using contact image sensors (CIS) should also be made judiciously.

When dealing with paintings and works of art, a CCD scanner is preferred so as to obtain best image quality, uniform color, and wide dynamic range. It is also ideal for scanning whole open books to obtain an image with little or no distortion. The geometric accuracy of this method is, however, inferior to that of CIS, and hence the latter are more suitable for scanning maps, engineering drawings, etc. The CIS scanner also has better resolving power since the scanned image is of the same size as the original. The resolution of the scanner is specified in dots per linear inch (dpi). The higher the resolution in dpi, the sharper is the scanned image. However, more resolution normally results in a larger image, requiring more memory for storage. The trade-off between the two depends on the use of the scanner. For example, official maps have to be scanned with much better resolution than the embroidery on a shawl. Large Format Scanners commonly available in the market have an optical resolution in the range of 150dpi to 800dpi, which would be sufficient for most general applications. The larger the scanned image, lesser is the enlargement involved, and lower is the resolution required. Highest resolution is desirable for scanning films.

Speed is another important criterion that influences our choice; speed is usually expressed in inches per second (ips) at a particular dpi. At a higher dpi, the speed will be less. For comparison, the speeds of all scanners are usually evaluated at 200dpi optical resolution, or at half the best optical resolution it provides. Most of the commonly available color scanners have speeds less than 300ips. Thickness of the media to be scanned is yet another factor to be considered when selecting the scanner type.

Jaime Gili Biography and his Art work

2007-10-28T23:49:00.001-07:00

Jaime Gili was born in Caracas (Venezuela) in 1972. He grew up in a multicultural capital full of vibrant optical art, a concrete city full of optimism. Caracas, in the late seventies, presented its own version of the International modernism movement in art and architecture. Its own take on Utopia, the look of the city being created by artists and architects working together towards a single vision underwritten by a strong oil economy.

In paintings such as Barbaro, Ochoa, and Trikalinou, Jaime Gili incites the austere purity of geometric design with the confidence and authenticity of painterly gesture. Presented in a cluster, his paintings are not hung, but leaned against the wall, creating a temporal architecture inciting of the constant transience and development of urban space. Executed with a palmy palette, Gilis large scale canvases capitalise on the power of aesthetics to motivate and allure. Bold splinters of pitch black, copper metallic, or tainted pink pierce through grounds animate with drips, smudges, and impassioned swipes, creating monumental fields of raw, potent energy.

Hailing from Venezuela, Gili works from a distinctly South American perspective. Influenced by the sharp geometric angles of 20th c architecture and the sleek elegance of classic automotive detailing, Gilis paintings disengage the international archetypes of modernism: reflecting instead a localised adaptation of style, where design and its social implications have been internalised and customised to represent a unique national and political identity and cultural heritage. Citing his countrys rapid oil-rich economic growth and intensive South American visionary developments such Caracas and Brasilia, Gilis paintings address this utopian new world optimism and its inherent failure.Gilis shard-like compositions are reminiscent of Ljubov Popova and Mikhaiul Larionov, while simultaneously paying homage to great South American abstractionists such as Cruz Diez, Jesus Rafael Soto and Alejandro Otero.

Conclusion :
Jaime Gili canvases are nostalgic for this obsolete positivism; where the idealistic development of public space and the appetite for mechanical amelioration both affirmed and inspired a sense of social buoyancy and community. Borrowing from the Constructivistss ideas of bridging art and technology.

Nano Particle Tech Uses for Molybdenum

2007-10-26T20:25:00.001-07:00

Finally, the financial markets have caught on as to how hot molybdenum stocks could get. While we began researching molybdenum about a year ago, and only first publishing in July 2006, molybdenum commentator Ken Reser has practically been the lone voice in the moly wilderness for investors. (We understand there have been several tout sheets hyping molybdenum stocks for nearly as long, but we cant include those in serious discussions about this metal.)

Now that molybdenum traders have grown more bullish about the metal, we expect molybdenum pricing to continue higher. Ferro moly prices have continued firming up. Some quantity is now selling at US$76 per kg in Europe. One report indicates a recent moly oxide sale at $31/pound.

The emergence of the Sprott Molybdenum Participation Fund (TSX: MLY; OTC Pinks: SMPCF) might only suggest the beginning of stronger institutional interest in primary molybdenum producers and on-the-horizon molybdenum producers those whose projects could be online by 2010 or sooner.

In March 2005, Ken Reser penned a short editorial entitled, Molybdenum: The 21st Century & Beyond Metal.

Mainstream analysts had not really bothered to investigate the numerous uses for molybdenum prior to Ken Resers discussion. Since then, molybdenum stocks have had an incredible run. Mainstream media, such as Canadas Globe & Mail, Dow Jones MarketWatch, The Australian and Londons Daily Telegraph have featured molybdenum in their articles and named some of the favored companies.

Now that molys time has come, many have passed Ken Reser by, aside from our Australian colleagues, FNArena.com. This is often the fate of pioneers who pave the road and point the direction where investors should head. Pioneers are oft forgotten, although streets are later named after them.

Thats not going to be the case if we have any say in this. Ken Resers moly repertoire has been extensive. Editorials since his seminal article have discussed moly uses in oil and gas de-sulphurization, catalysts, coal liquefaction, energy pipelines, oil super tankers, drill stem tubing, super alloys, nuclear reactors and turbines among others.

What many thought was fiction Reser preached, more than two years ago, are ideas now at the forefront of mainstream discussions among highly respected analysts. The International Molybdenum Association (IMOA) should be thankful Ken Reser attracted such a high level of investor interest to the moly mining sector over the past two years.

Well, the pioneer is alive and well. Ken Reser has more insights into molybdenums future. And we invited Ken to publish them in his commentary below.

Ken Resers Commentary

Little attention has been given to a few other aspects of this metal of mystery, in a world growing and changing so rapidly. I have little doubt there are more than a few uses of moly. New discoveries are waiting in the wings.

One case in point is Nano-Particle technology involving molybdenum.

Document Management Systems

2007-10-25T20:58:00.001-07:00

Documents are an integral part of any business process and play a pivotal role in the functioning of any organization. They are a vital means of organizational communication, an important constituent of organizational memory and play a significant role in enhancing the business process.

Business corporations and other organizations generate billions of pages of paper documents every year. For this reason, they need an efficient document management system that can facilitate the systematic filing, storing, securing and retrieval of information. For some organizations such as insurance companies, solicitors and consultants, an efficient document management system means better service and greater business prospects.

A document management system can manage documents using computer software. It also includes management of audio and video files, graphics, photographs, faxes and emails. It is the process of organizing, storing, securing, classifying and retrieving document-based information and multimedia files. Since the ideal of a paperless office environment could not be achieved, document management systems also have to adapt n effectively meeting the demands of various industries in storing, retrieving and sharing information with paper as well as electronic documents.

Document management systems involve, document capturing using scanners and optical character recognition to convert paper documents into digital data, installing document management software for creating and organizing documents and for database management, and workflow management for the systematic transmission of information.

Document management systems facilitate the long-term storage of documents. They enable digital archiving; that is, categorizing and storing documents, which are currently needed, and those that have become outdated. Sharing information in the form of text, graphics and multimedia is made convenient by easy access through the Internet or via the companys intranet, according to an individuals need and priority. A document management system allows for the systematic indexing of documents, making it easier for the user to identify and locate the required document on request. It also reduces the number of man-hours required to manage the documents.

A good document management system is central to the efficient managing of documents, as well as in enhancing communication and sharing information within the organization.

More Profits with VoIP Termination Business Plan

2007-10-25T01:32:00.001-07:00

Business sector has being expanding by folds and leaps and with this the competition to survive in the industry while making good profits has increased too. Their business requirements are evolving and in order to keep up with the current situation corporate houses are looking at alternate ways to save more while increasing their productivity. They are beginning to experiment with diverse communication capabilities which are offered by the World Wide Web. The Internet is offering contemporary modes of communication which helps the business houses to save more thereby increasing their revenue generation.

VoIP termination business plan meets the ever changing communication needs of the industry. It exploits the benefits of World Wide Web to transfer voice, data and video traffic through a single channel unlike the traditional mode of communication which would work through optical fiber wires. This not just increases the efficiency but also brings down the cost of operations. VoIP technology is perhaps the only one among all channels of communication which has the least hardware requirement.

VoIP call termination helps to combine the business data with the phone call. For instance, click to call service on the website for customer interaction or a screen pop up for user interaction can be achieved through this technology. This benefits the organizations by raising customer satisfaction; something that every business strives to achieve in order to build up its brand and brand preference. There are many VoIP service providers offering a-z call termination services.

In the global economy that has permeated in the current business scenario, corporates have to remain in contact with their dealers, suppliers and customers from world over. This means rise in telephony expenditure due to expensive call tariff for long distance and international calls through public switch telephony network. VoIP business plans offer a much cheaper and quality substitute to PSTN and allow calls at almost half the cost paid for PSTN. Thus, savings in telephone bills is huge through the use of voice over IP.

VoIP business plan can help to integrate different branches of your company helping you achieve a seamless communication network at no cost.

Industrial Directory

2007-10-24T22:57:00.001-07:00

An industrial directory cannot but be a substantial volume. Industry is defined as production of goods and the variety of goods are bewilderingly large. A directory can claim to be an industrial directory only if it covers all major sectors.

Speaking of sectors, NAICS - North American Industry Classification System - classifies economic activity in United States, Canada and Mexico. We look at this system in the next section.

Industry

NAICS has allotted a sector number to each sector (listed in the first column below).

11 Agriculture, Forestry, Fishing and Hunting
21 Mining
22 Utilities
23 Construction
31-33 Manufacturing
42 Wholesale Trade
44-45 Retail Trade
48-49 Transportation and Warehousing
51 Information
52 Finance and Insurance
53 Real Estate and Rental and Leasing
54 Professional, Scientific, and Technical Services
55 Management of Companies and Enterprises
56 Administrative and Support and Waste Management and Remediation Services
61 Education Services
62 Health Care and Social Assistance
71 Arts, Entertainment, and Recreation
72 Accommodation and Food Services
81 Other Services (except Public Administration)
92 Public Administration

Each of these sectors is subdivided into sub-sectors by using additional digits in the sector number, as illustrated below:

32 Manufacturing
326 Plastics and Rubber Products Manufacturing
3261 Plastics Product Manufacturing
32611 Plastics Packaging Materials and Unlaminated Film and Sheet Manufacturing
326111 Plastics Bag and Pouch Manufacturing
326112 Plastics Packaging Film and Sheet (including Laminated) Manufacturing

You would notice that even under the lowest classifications, such as Plastic Bag and Pouch above, there could be several specialized activities. A detailed and complete list of industries would thus be a very big list indeed.

We take a look at some sample categories in a reputed industrial directory in the section below.

Industrial Directories

Adhesives & Sealants Adhesives, Adhesive Tapes, Pressure Sensitive Tapes, Tapes, Adhesive Dispensing Equipment, more...

Automation & Electronics Automation Equipment, Printed Circuit Boards (PCB), Electronic Enclosures, Clean rooms, EMI/RFI Shielding, more...

Chemicals Coatings, Corrosion Resistant Coatings, Desiccants, Optical Coatings, Teflon Coatings, more...

Custom Manufacturing & Fabricating Metal Fabrication, CNC Machining, Metal Stampings, Screw Machine Products & Turned Parts, Tube Fabricating & Bending Services, more...

Electrical & Power Generation Transformers, Batteries, Magnets, Custom Transformers, Neodymium Magnets, more...

(Source: http://www.thomasnet.com/ )

We have not included several more major categories in the partial list above. As you see from the extract above, the sub-categories are large enough for this industrial directory to take recourse to "more..." when listing the sub-categories.

CD Rom Backup Software

2007-10-23T21:29:00.001-07:00

Creating backup for the data on an electronic device like a computer or a digital camera is very important. Most electronic equipments are bound to suffer crashes, leading to the erasing of all the data within. Creating backup for the data enables not only storage but also effective retrieval of the data whenever required.

There are many backup devices, including floppy disks, hard disks, other computers on the network, compact disks, and DVDs. Each of these has its own conveniences, risks and capacities. Use of these devices depends on several factors: the amount of data to be stored, the frequency at which the data is altered, presence of other backup devices, and the kind of files that need to be stored.

CD ROMs are one kind of a removable backup device. CDs are being increasingly used for storing files as they are inexpensive, easy to store, easy to transport, and have varying storage capacities. Some CD ROMs can take as much as 700 MB of data. They are also relatively safer than floppy disks or hard disk on the system. The data stored on a CD ROM however, cannot be altered. This makes them more ideal for storing permanent data. There are also other advantages from using CD ROMs for storing backup data: they have a high shelf life, they are not affected by magnetic fields, and they can be taken through airport security without any problem. They are nevertheless fragile and require careful handling.

CD-ROM recorders or writers have now become very inexpensive. A basic model is available for a price below $1,000 while those with optical drivers are more expensive. These days, most backup software programs are compatible with CD-drives and CD-recorders. There are many kinds and brands of backup software programs available. These are compatible with basic Windows NT/2000 configurations. Prices range from $30 to $3,700 or more, depending on the options and the features available. Veritas, Symantec, Acronis, Dantz, and Stomp are some of the popular brands in CD ROM backup software.

D-Link DCS-6620G wireless PTZ IP Camera Review

2007-10-23T02:40:00.001-07:00

Remotely monitoring premises using internet protocol (IP) camera equipment is a relatively new technology arrival even more so with wireless equipment capable of pan-tilt-zoom (PTZ) with wireless connectivity. I purchased the D-Link 6620G for the rich feature set and this article briefly summarizes the good, the bad, and the ugly of this unit.

As an owner of a holiday property located thousands of miles away from my home residence, I was seeking to deploy surveillance technology that would enable me to know in real time of any intruders or events at my property. The ideal solution was presented with the D-Link DCS-6620G as a wireless IP camera that could be accessed over the internet from anywhere in the world. Does it work? Yes, well, sort of read on.

Once it is all setup and functioning properly, the interface to pan, tilt, zoom is very straightforward. Clicking a snapshot is a breeze as well as jumping into the configuration. The interface here deserves high marks.

Unless you have a PhD in Computer Science, you will likely struggle to get the unit working. The manual and help line to D-Link are of little value prayers to religious icons and perseverance are your best resources here. Unless you have extensive experience and training, the connectivity is probably the worst trait of this technology. The manual is absent of any detail or worked examples. First, the SMTP server details do not require you to enter 'smtp.' or 'smtp:' in front of the smtp server details field Likewise, for FTP, do not enter 'FTP://'. For your wireless connection, be sure to get the SSID of your wireless access point or router first and type it in exactly. The Site survey feature did not see my access point in the lounge at all, only the router in the study. You'll also need to know to open Audio, Video, HTTP, local FTP, and Server FTP ports on your router before you'll have any joy with this camera. Not to mention establishing Dynamic or Static DNS hosting details (which there is only a drop down menu for these and unless you subscribe to one of them, you are out of luck). The documentation is sparse on all of this and calling D-Link for over 2 hours each on 4 separate calls frankly did not help me to resolve. Thanks to my local ISP technician who had already installed a TrendNet camera who was able to assist me joggle through it.

Once operating, you will notice the base of the unit gets very hot and given only 1 mounting point leaves this $800 unit very vulnerable to being bumped about or snapping off and falling to the floor. Images are very clear until you zoom on an object. I disabled digital zoom in order to limit the camera to the optical zoom, but even when zoomed 70% (like on a license plate on a car) you cannot focus the unit enough to distinguish the numbers.

You cannot use both FTP and SMTP (e-mail) settings simultaneously - you must select either one or the other. The camera only uploads snapshots to FTP or e-mail, not video. For video playback, you must record real time motion to a local computer running bundled software. This is not a problem for situations where you have a local computer on the LAN, but presents a considerable problem for a remote installation where you do not necessarily need computer equipment. For a remote installation, about the best you'll get are a few snapshots of the event, not real motion video uploaded to your e-mail.

Data Recovery over Hard disk failure

2007-10-22T22:34:00.001-07:00

Hard Disk: An Introduction
--------------------------
Hard Disks are used to store information. All information on computers are stored in files. Hard disks store the majority of information on today's modern computer. Hard disk drives (HDDs) can be critically damaged by static electricity, shock, and other factors, often resulting in failure or the loss of valuable data. In many cases it may become necessary to recover information from your hard drive. Such retrieval is quite possible.

Hard Disk Failure
-----------------
*Physical Failures
Physical failure occurs from sudden switch off, power failure, sliding them off desks and cheap components. As for data loss, data is only magnetic impulses on the surface of a hard disk. And ridiculously small bits of magnetism at that! When the magnetic impulse fades, or changes position, trouble starts.

Drive Alignment Drift is another cause of problems. Mechanical devices are subject to wear and tear, heat and cold, loosening tolerances etc.

The small changes in the read/write heads wouldn't matter usually, as data still gets written in the same place as it will be read later. However, there is some data that hardly ever gets re-written, and that is the Sector ID Headers.

*Logical Failures
Master Boot Record Failure
Technically, when the Master Boot Record is working correctly, the master boot code scans the partition table for the active partition, finds the starting sector, loads a copy of the boot sector from the active partition into memory and then transfers control to the executable code in the boot sector. If the master boot code cannot complete these functions, the system displays a message similar to the MBR error.
*Boot Sector Failure
The boot sector is a region of a hard disk, floppy disk, and other similar data storage device. It is loaded to memory and executed as a part of the bootstrap sequence. The boot sector contains a small computer program that is loaded on the operating system into memory and transfers the control.

Most boot sector failure occurs by the defection of boot sector virus. Boot sector viruses are usually spread by infected floppy disks. In the past, these were usually bootable disks, but this is no longer the case. A floppy disk does not need to be bootable to transmit a boot virus. Any disk can cause infection if it is in the drive when the computer boots up or shuts down.

*Accidentally Deleted Data
Some time some how you may delete a file thinking we don?t need it any more, but in a week or or two you may realize that it is a needed one. It happens to the best of us, but fortunately there are ways to get these lost files back.

When it comes to data on your computer, it is almost impossible to accidentally remove it beyond recoverability. Even if you are intentionally trying to completely wipe a file from your hard drive it is exceedingly difficult.

*Cross Linked Files

A file system error that corrupts the contents of an existing file by writing data from another file into the same cluster. Running Scandisk or a similar program cleans up the problem, but one of the files is no longer usable.
*Bad Sectors
It is a portion of the Hard disk that cannot be used any more. If a part of the disk get bad sector which contains data then those data is to be recovered before use. When you format a disk, the OS will mark all the unusable sector as bad sector, however, this does not affect the overall performance of the disk as the damaged space is considered unusable.
Hard Disk Data Recovery
-------------------------
*Replace the (Circuit Board) PCB Upon a Hard Drive circuit board failure, it is possible to get back the data by carefully replacing the PCB of the hard drive.

*Replace the Firmware
Hard disk firmware is the information that is used by the computer that allows it to correctly interact with the hard disk. It may be replaced or updated by the matching firmware.

*Replace the Head Stack
There are common situation that may be due to head failures. There is a small chip located in the head stack that is called PREAMPLIFIER. Working with preamplifiers always includes some difficulties, because, practically, they can not withstand static discharges. If re-soldering is needed, one should follow a number of rules to protect a preamplifier from static damage caused by careless finger touching. Although this task is very risky and it should be done in a high secured lab specially created for this task.
*Move the disk to another Drive
In some cases complete functionality of the Hard drive may be disabled while only the internal disk plate is without any damages or errors. In those situations, it is possible to move the disk to another drive.

*Spin-Stand Testers
Hard drive manufactures and their head media; preamplifier and read channel suppliers do have very accurate, very expensive "magic machines" called Spin-Stands. These are used for testing and experimenting with heads and disks. They are used mostly by researcher and development departments.

*Magnetic Force Microscopes (MFM)
Magnetic force microscopy is a powerful tool for high-resolution magnetic imaging of most data storage media. As the density of magnetic media is higher, the bit becomes smaller than the wavelength of light, so optical techniques can not resolve it. General MFM is capable of imaging the magnetic domain of several tens of nanometers. Also, MFM is almost simultaneous with measuring the surface characteristics of topography and roughness of the same area with sub-angstrom vertical resolution.

Recovery Softwares
-------------------
*SpinRite 6.0
SpinRite is a stand-alone DOS program designed to refurbish hard drives, floppy disks and recover data from marginally or completely unreadable hard drives and floppy disks and from partitions and folders which have become unreadable.

*Ontrack data recovery software Ontrack Data Recovery offers the industry's highest quality and cost-effective do-it-yourself data recovery software solutions for almost any data loss situation covering servers, desktops or laptops for all media, operating systems and file types. Ontrack's EasyRecoveryTM family of products is unmatched in its ability to recover/repair from all causes of lost data.

*Recover My Files Recover My Files data recovery software will easily recover deleted files emptied from the Windows Recycle Bin, or lost due to the format or corruption of a hard drive, virus or Trojan infection, and unexpected system shutdown or software failure.

History of the camcorder

Remember the 80's when everyone was walking around with one of those big camcorders on their shoulders? We thought they were the greatest invention since sliced bread. But most of us had no idea how they evolved. It was quite a journey and, as we all no, sure didn't stop there.

The original field of the video camera was in television broadcasting. The were two separate, very large pieces of equipment used in to different locations. The cameras were mounted on special trolleys and wired to the recorders. As with everything, as technology progressed, before long they were able to make units in a much smaller size. A portable unit was made up of two pieces, the video camera and the VCR, both being mobile. The VCR was made up of a cassette player/recorder and a television tuner or receiver. Because the units could be detached from one another usually meant filming was always a team effort. The camera cases for this equipment is as large and cumbersome as the equipment itself. Going on location means crating the camera equipment and shipping it to its destination.

Filming remained the job of two until the introduction of the first professional camcorder by Sony, in 1982. It's name was Betacam. Sony's slogan for the Betacam was "Inside This Camera Is A VCR". But it was going to take more than a slick slogan to sell the cameramen. They were used to having a video engineer handling the VCR equipment and now that was going to be their responsibility. However, once the cable between the two (cameraman and video engineer) was removed, the cameraman realized unlimited freedom and it has remained the film industry's filming standard ever since. This type of filming has also come a long way. There is a new concept of portable television studios that is becoming popular among those who film on site such things as aerial shows. The equipment needed can be packed in a set of quality camera cases with dividers that provide storage for carrying extra lenses and other accessories.

From the professional Betacam came the first camcorder available to the general public in 1983, and they called it Betamax. It was too large to operate by one hand, thus the shoulder method of shooting became popular with the average citizen making films of their grandchildren. Most units are designed for the right-handed person. And, because they had only optical viewfinders, with no playback or rewind capabilities, some camcorders got larger before they started to get smaller. The cases for these earlier camcorders were generally a hard suitcase type case with a cut out space inside for the camera and each attachment. Camera cases now have many features for ease in carrying and use including the ability to load your equipment into the case two ways.

The early 80's brought us two new formats, VHS-C (VHS with a smaller sized cassette) and the 8mm, in the form of the KodaVision 2000 in 1984 from Kodak. The rest is history. The first conventional viewfinder became an option through Sharp in 1992 when they introduced their color LCD screen. This feature is on almost all camcorders today and has revolutionized the ease of domestic filming. Basically, turn it on and point it at what you want to make a memory of; that's all there is to it. The most recent big breakthrough in camcorders was the arrival of the digital, which took place in 1995. Panasonic and Sony were the leaders with their Digital Video camcorders, but Sharp and Jvc wasted no time getting their products on the market. The camcorder has continued to shrink in size and are now small enough to hold in the palm of your hand. Cases area appropriate to the size; no longer hard, heavy, cumbersome suitcases. They're lightweight and come in attractive fabric and colors.

The Switch from Film to Digital Camera: Making the Adjustment

2007-10-19T19:53:00.001-07:00

From all of the books, advertisements, and products in stores it would appear that no one continues to use a film camera. This isn't true of course. Although a digital camera can offer much greater control during the editing process and perhaps even a cost savings over the long run, a traditional film camera still has advantages for some consumers. One of those being that if their film camera is a good one and meets their needs, there is no reason to change.

However, for those who do decide to switch to a digital camera there will be significant differences to which they must adjust. Certainly the technology behind a digital camera makes them different; how images are captured and stored, the optics themselves, pixels, resolution, and so forth. But there are a handful of basic changes to which even those who photograph on a very limited and casual basis will need to adapt.

Response Time

With a more affordable, point-and-shoot type digital camera there can be a significant delay between pressing the button and the camera actually taking the picture. These cameras are somewhat like a small computer. During the lag time it is focusing but this can cause some great shots to be missed.

Of course, spending the time to shop for a camera with less lag time is one solution; and certainly many of the more expense models don't suffer this issue. However, there is a simple adjustment which can produce a significant reduction in the lag time. The photographer can set up the shot, aim the camera at the subject, and press the button down half way and hold it. At this point, the digital camera will begin the process of focusing. Then, a couple of seconds or more later, when the photographer and subject are ready, the button is depressed entirely and the picture is taken almost immediately. Obviously, this requires the photographer to anticipate and prepare before taking a shot.

Battery Life

Because much of what a digital camera does consumes energy from the battery, they are known to drain batteries very quickly. One of the particularly power greedy functions unique to a digital camera is that of powering an LCD screen. Again there are a number of things users can do to assure they don't run out of power and to reduce the rate at which the camera uses the energy.

To avoid a trickling discharge, batteries should be removed from the camera when the device won't be used for more that a week or two and, likewise, a digital camera should be powered off if the user doesn't anticipate taking a shot for another 30 minutes or so. Using the "sleep mode" is good also, to assure that even if the user forgets, the camera gets powered off.

Using the viewfinder instead of the LCD screen to frame shots is wise when you wish to save power. Users can also avoid using flash whenever their subject is more than 12 feet or so away, since the flash will be ineffective anyway and drain power needlessly. Those traveling with a digital camera also need to be sure to carry a backup battery to avoid problems.

Purchase Order Financing- The China Advantage

2007-10-18T23:54:00.001-07:00

Purchase Order Financing- The China Advantage explores why manufactured imports from China to the United States of America are on the rise and how you can benefit from this trend with purchase order financing a from commercial finance company.

As of July, 2007, the Central Intelligence Agency for the United States government estimated that the population of China is over one billion three hundred twenty one million people. In contrast, the population of the United States is estimated to be a little over three hundred two million people. Thats 1,321,000,000 versus 302,000,000 people; China has over four times the population of the U.S.

In the past two decades China has completed and put into operation over 2000 large and medium-sized industrial projects; these include railways, atomic power stations and completely new cities. There has been ginormous investments in other fixed assets such as basic industries, 100,000 new reservoirs for water storage, irrigated land, coal mining, oil-drilling, steel-making, power generation, highway construction, and newly constructed and extended ports.

China has the worlds largest manufacturing workforce- over 100 million people. In comparison, there are about 14 million manufacturing workers in the United States. Chinas labor costs are low compared to the United States and many other parts of the world. As of 2002 statistics indicate that employees in Chinas city manufacturing enterprises received about $0.95 per hour; rural workers average about half this amount: $0.41 per hour. A large majority of manufacturing employees work outside the cities. They earn about 3% of the average hourly compensation of factory workers in the U.S. and many other developed countries. With low land costs and low labor costs it is no wonder that the cost advantage to manufacturing in China is extremely attractive to American entrepreneurs. When their products are manufactured with sufficient quality controls, the cheaper costs and effective delivery systems create a win-win situation for those who are able to participate.

Manufacturing is a basic Chinese industry. When you take raw materials and labor and produce products that can be sold in high quantities at a lower cost than U.S. competitors, and successfully import to them to the U.S. and it is possible to have excellent returns on your investment. And Chinas political and economic system is relatively stable compared to other developing nations such as many countries in Africa.

What is the approximate size of the trade in goods from China? According the U.S. Census bureau, Foreign Trade Division, imports from China in 2006 were over $287 Billion dollars; for the first five months of 2007 imports from China were over $120 Billion dollars.

What are the main categories of products imported into the U.S. from China? This includes iron and steel products, specialized industrial machinery, office machines and computer, telecommunications and sound equipment, electrical machinery and parts, road motor vehicles, building and lighting products, furniture, travel goods and handbags, footwear, professional, scientific and controlling instruments, photographic and optical equipment, timepieces, personal care products, and food products such as tea. According to the American Electronics Association, high-tech imports from China are on the rise.

So whats the lightest notebook computer anyway?

2007-10-18T19:50:00.001-07:00

I went looking for the lightest notebook computer the other day and after a couple hours of searching I was getting pretty frustrated. "Ultalight notebook computer", "light weight notebook computer" - I kept trying different approaches.

What I found was a lot of old machines - 1, 2, even 3 years old. And a ton of spam websites that took my search keys and created a dynamic page. That left going to the manufacturers and looking at actual product specs to see who actually has the lightest notebook computer. Fortunately I finally found a list to start from so here they are - the light weights.

The Fujitsu LifeBook Q2010 weighs in at 2.2 pounds with a 12.1 inch screen. Unfortunately it has a 1.2Ghz processor and a 30 GB hard drive though it comes with XP Pro and a DVD writer.

The Dell Latitude D420 also has a 12.1 inch screen and is significantly less expensive but again 1.2 GHz and a slow (4200rpm) 30 GB HD and it weighs around 3 pounds. It also comes with 512MB of DDR2-533 SDRAM on an integrated DIMM. The upgrade to 1GB or to 1.5GB is reasonable, but the 2GB configuration costs an extra $1000 (probably because it requires a 1.5GB DIMM).

The Sony VAIO VGNTX750PB weighs 2.76 pounds. it has a smaller screen (11.1 inches) than some of the others, a 1.2 GHz processor, but it includes an 80GB hard drive and a DVD+-RW dual layer combo Drive. The memory is upgradeable to 1.5 GB.

The Lenovo ThinkPad X60 at 3.3 pounds has a 1.66GHz Core Duo, a 12.1 inch screen and a 60 GB hard drive. The memory is theoretically upgradeable to 4GB, but it has no optical drive. You need to get a ThinkPad X6 Ultrabase to add a CD or DVD drive. That kind of hampers its mobile uses.

The Averatec AV2260, weighing in at 4 pounds, comes with a 1.8 GHz AMD Turion 64 Mobile, a 12.1 inch screen, 1GB installed DDR-SDRAM, an 80GB hard drive and a DVD+-RW Dual Layer Combination Drive. So it's a little like an overweight Sony on steroids. It's also the least expensive of the six lightweights. The others run from around $1200 to over $2300 depending on the seller and configuration.

Though slightly heavier at 4.4 pounds, the HP Compaq nc6400 is unusual in having a 14.1 inch Wide XGA screen. It comes with a 1.83 GHz Intel Core Duo Processor, 1GB of DDR2 SDRAM, a 60GB hard drive and a DVD/CDRW Drive. The lowest price I saw in a quick search, was $1259.99. Most of the models I saw were being advertised with 80GB drives and DVD+-RW/DVD-RAM optical drives, rather than the 60GB and DVD/CDRW drives.

Obviously the lightest notebook computer in this list is the Fujitsu. If you really want an ultralight notebook computer then you will have to accept some sacrifices. Personally, I think I'd rather have a more capable machine. I also don't like the small screen sizes on the very light notebooks.

As with any computer purchase it's critical that you carefully analyze just what you're going to do with a machine. Lightweight notebooks are nice simply because they're less hassle to lug around, but there compromises involved that may make extra weight a less significant issues. Aside from tending to be more expensive, a light weight notebook computer will almost always have a smaller screen and a more compact keyboard than heavier notebooks. The real question you need to ask yourself isn't "What's the lightest notebook computer?" it's "What's the lightest notebook computer that meets my requirements?"

Clear Platform shoes-A Guide

2007-10-17T19:35:00.001-07:00

Shoes are definitely an important element of women's attire. Many ladies have a variety of shoes for every occasion. Some shoes are like comfortable old friends. Although the footwear is nothing spectacular to look at, the familiar comfort makes the pair a long-time favorite. Other shoes complete an outfit or are only suitable for certain activities. For instance, rock climbers would be unwise to wear sandals while ascending a mountain. More than just foot coverings, various shoe styles have specific purpose. Platform shoes are clearly no exception. Sexy clear platform shoes are professional, playful, and purposeful.

When most people consider sexy clear platform shoes, a couple of occupations probably come to mind. Sexy clear platform shoes are popular in the nightclub setting. Scantily clad waitresses popularized the clear platform footwear for the optical illusion of being taller, with longer legs, and walking on air. However, walking on platform shoes takes some practice and finesse, so delivering snacks and drinks to waiting customers can be a challenge. Also, the shoes must have a level of comfort as well as beauty, or many women might go home with exceedingly sore feet, after wearing the sexy clear platform shoes for an entire shift.

Another group of nightclub employees also have assisted in the popularization of sexy clear platform shoes. Pole dancers and strip tease artists wear sexy clear platform shoes in the performance of dancing and entertainment. Giving the impression of sexier, shapelier legs is a turn on for the people who frequent these establishments.

However, the need for sexy clear platform shoes has taken on a playful purpose within the home. Generally, women prefer men stay at home for excitement, entertainment, and pleasure. By wearing sexy shoes at home, women can playfully encourage men to satisfy, at home, the needs answered by participating in public nightlife. From head to toe, men are reminded that women are much more than the comfortable partners who take care of the house, the chores, and the children. Sexy clear platform shoes can help renew the excitement of first love, and the joy of being together before growing responsibilities got in the way. So, rise to the occasion and have feet dressed for fun.

Having the fun of wearing sexy clear platform shoes is not only for the nightclub scene or an intimate night for two. The shoes are also a purposeful fashion statement. For example, many women are petite and must look up to the rest of humanity. No more! In six-inch platform shoes, women can instantly become a head taller in a fun and fashionable shoe. Seeing others eye-to-eye also builds self-esteem. During social gatherings, petite women no longer have to feel lost in the crowd. On romantic walks, short women are not doomed to be tucked into a partner's armpit. For the women of average height, sexy clear platform shoes are simply an awesome fashion statement. Platform shoes can be a conversation piece, complete a great outfit, or simply be fun.

In summary, sexy clear platform shoes are a multipurpose style. Petite women, or women wanting to leave a lasting impression will find this particular shoe interesting. Being clear, the platform creates the illusion of walking on clouds or drifting through the crowd. Although the style likely first became popular with women working in nightclubs, the sexy shoes also complete an alluring outfit for intimate encounters. Regardless of the reason, sexy clear platform shoes are always a purposeful fashion statement.

London bathroom fitters: Bathroom visual enlargement.

2007-10-17T01:27:00.001-07:00

Huge bathroom with a wall-sized window, stylish plank beds and view of veranda with Japanese rock-garden is impractical dream for the large majority of us. In limited urban environment all we often have is just four-squared box. And even rather large bathroom sometimes is not enough for realization of all our design plans. As well-known stepmother from a fairy tale "Cinderella" had said - "The kingdom is small, there is no room to be on the loose". You can't enlarge your bathroom even at the expense of your neighbours because of chief wall. But maybe it's better to solve this problem with the help internal reserves and to expand your bathroom environment visually? Maybe, it'd be better to help out missing square meters just virtually, by creation of their visibility?

Design. You've got to start with bathroom design for competent disposal of available space. Development of modern installation systems allows placing of all bathroom and lavatory equipment not in its common places but in places where you need it to be; you can save some tens of inches or even a few meters and free some space visually. For example, you may save some space with angular installation of not only bath and shower cabin, but wash basin or toilet bowl. The bath or shower cabin may be completely or partially hidden in a niche if such technical feasibility is available.

Bathroom and lavatory equipment. If space available is not as huge as you want, you can easily save it by choosing of small bathroom equipment specially designed for small bathrooms which consumes much less space than standard equipment. In that case the doll's house effect is triggered and the environment around diminished pieces of equipment seems to be larger. By the way, many people think that space-saving toilet bowls and bidet are even more convenient, than standard ones. Of course you can't say that about a small wash basin or a bath. Hanging bathroom equipment is of interest, too, as it visually frees some space; bathroom equipment like "two in one", for example, tandem of shower and bath, is popular as well.

Walls. The walls play the most important role in visual enlargement of bathroom space. You should never use shadow toned ceramic tile and other types of covering in small rooms, especially in combination with large decors and wide borders. The tile is to be light toned. In was considered for a long time that large ceramics was to be used in small rooms. Nevertheless, practice shows, that mosaic makes even a small room visually larger.

Necessary effect of depth is achieved with ceramic tile and furniture of light, deep tones and shades in combination with medium-sized and soft-core decor, narrow decorative borders especially placed not horizontally, but vertically. Panels are outside the fold, even the large ones, but only those including perspective view: landscapes, especially marine, imitation of view from a window, the sky and so on. Your look does not die against them but flies away. Photo panels are the latest thing in decoration of rooms.

Digital Cameras: Getting Better Photos of Family and Friends

2007-10-09T23:08:00.001-07:00

Taking photographs of the people in your life is simple with a digital camera. We all have collections of images which represent the important people and events in our lives. Some of the pictures are great, but some leave our subjects stiffly posed, lost in the sea of a cluttered background, and often lacking personality as they stare back with the same "posed" face as in every other photograph. So how do we capture the detail and the personality so that the image saves for us a more meaningful record of a moment or a person?

Obviously, professional photographers take control of the background and lighting, direct the pose of their subjects, and use a great deal of creativity with props and camera controls to assure the highest quality image. For the average person however, candid shots are more effective in capturing the true meaning or personality at a given moment. For these individuals, following just a few basic tips can go a long way in obtaining photographs that will become a treasure for many years to come.

The subject should be the focus of the picture. Avoid a cluttered background so that it does not distract from the subject. Using the viewfinder allows the photographer to determine how the shot will look. If the background is too cluttered the subject can be moved, but in more candid shots of individuals, holding the digital camera in a vertical position sometimes helps to eliminate some of the background.

Step in close to capture more detail. For an image that captures the true personality and emotions of the subject, a photographer must get facial detail. When taking a candid shot and stepping in closer would disrupt the moment, use of the digital camera's optical zoom or telephoto can have the same effect.

Some shots don't require posing. Many of the most meaningful shots are taken as subjects interact or are engaged in an activity. From images of children at play, a spouse reading the morning paper, a parent and child talking, or grandma gardening these are the moments that reflect the true personality of subjects.

Happy is good, but there are other emotions worth capturing. It adds depth to a subject when images reflect other feelings such as humor, concentration, relaxation, or even boredom.

A relaxed subject makes for a better photograph. When posing subjects, many photographers suggest talking to them to get them to relax and reveal more of what they are feeling or thinking. A natural, relaxed posture will provide a better image than that of a person standing rigidly with their arms crossed. A subject may be seated with their head resting on their hands or standing with their head at an angle and hands in their pockets; posture varies in real life and should be varied in photographs as well as it reflects the subjects mood.

It is sometimes acceptable for a subject to be looking away from the camera. Just as with expressions on the face and posture, variations in where a subject is looking can work well in capturing a more meaningful image. Whether it is a child daydreaming as they gaze out of a window or simply an attempt to catch the profile of an adult as they drink their morning coffee these images which most accurately capture a subjects personality don't always require that they face the camera directly.

Digital camera flash units

2007-10-08T01:10:00.001-07:00

Digital cameras flash units come in many shapes and sizes. Low end digital cameras include low energy built in flash units. High end digital SLR cameras can support sophisticated external flash units which can provide superior lighting in difficult scenarios. Here are some basic facts about flash units both built in and external.

Flash units came a long way since their early days. Back then flash units were using powder that was lit by electrical current and literally blew up to produce the light energy. Using these flash units was a risky business. It was also difficult as the flash units were not automatically synchronized to the cameras shutter. The photographer had to make sure that the flash goes off at the exact right time synchronized with the shooting of the photo.

Nowadays flash units are sophisticated technology devices. They use an electronic flash tube that is automatically synchronized to the camera. The photographer merely needs to do nothing. New digital cameras can decide on their own if the flash is needed, they can set its intensity and other parameters and they can fire the flash at the exact right time when the shutter is opened. All this is done automatically in the background. Digital camera also provide the user with the ability to manually control the flash, force it to either fire or not to fire, set its intensity and more.

Flash units are divided into two categories: Internal built-in flash units or external flash units. Internal flash units are built into the camera. Almost all digital cameras include such a unit and allow the user some control over it through the cameras menus and buttons. External flash units are attached to the cameras body through a dedicated slide-in slot or by using an electrical cable. Not all digital cameras support external flash units. Usually the lower end pocket cameras do not allow external flash units while all high end digital SLR cameras do allow such external flash units. External flash units can vary a lot. They can have different light energy levels that they can emit and different mechanical characteristics. Some external flash units also include smart sensors to measure ambient light, distance and other optical parameters in order to optimize the flash effect.

Digital cameras can use their flash units in automatic or in manual mode. In automatic mode the camera measures ambient light and fires the flash when not enough ambient light is available. Sometimes the camera will make the wrong decision as to using the flash and will either fire or not fire the flash when the opposite was needed. Setting the flash intensity is important too. If the flash unit fires too much light energy on objects that are too close to the camera the digital photo will be washed out. On the other hand if the flash unit fires a small amount of light energy on an object that is farther away from the digital camera the digital photo will be a too dark.

Flash units have limitations too. They can not light any scene and any object at any distance from the camera. It is important to know your flash unit limitations. For example check what the maximum light energy that it can emit is and what the farthest that an object can be effectively lit from. This is also known as the effective flash range. If the object is out of the effective flash range it is actually better to turn off the flash altogether and use a tripod with a longer exposure. Sometimes it is useful to use the flash even if there is enough ambient light. In such cases you can manually force the camera to fire the flash. This is also known as fill-in flash as it is usually used to fill-in shadowed areas on objects in the digital photo.

Enjoy the View - Use a Binocular

2007-10-05T20:45:00.001-07:00

A binocular, or set of binoculars, is a tool used to view distant objects and make them appear closer to the viewer. Using both eyes, a person watching a football game seated far from the field can get a clearer view of the action as it happens despite his distance, with the use of a binocular.

Many people in the world enjoy their choice of sports using these gadgets with designs which can go from compact and light, to the bigger, full-sized models. Police surveillance teams and people involved in government intelligence also find a set of binoculars an indispensable tool in their jobs.

Bird watchers also make up a large number of binocular users in the world. Their personal satisfaction of watching birds in these animals' natural environment is only made memorable with the use of high-power binoculars.

These people require more from their binoculars. Their gadgets must have the needed viewing power to meet their needs, lightness for easy transporting, and most importantly, durability to last years of continuous use. These viewing gadgets must be easy to hold, and protected from moisture and dirt. The resolution of a binocular must be able to reveal details and true colors accurately. They must also be able to quickly focus and work well in weak lighting conditions. Lastly, these gadgets must be able to show the real picture for bird watchers wearing eyeglasses and contact lenses.

Binoculars are easy to use and more advantageous than telescopes and monoculars. They allow viewers to use both of their eyes simultaneously, and viewers are offered a superior experience, allowing them to follow fast movements easily. These tools further allow easier viewing of fast moving objects such as race horses than a telescope of monocular.

Binoculars work by passing the image through two adjacent lenses and prisms. The prisms then revert the image, by the internal reflection of available incoming light. Images are then displayed right side up rather than inverted as what astronomical telescopes do. The magnified image then becomes available to the viewer's both eyes.

The magnifying power of a binocular is described by two numbers separated by "x", e.g., 3x10. While the first number determines the magnifying power, the second number displays the objective lens' (the lens which is further from the eye) diameter in millimeters. Models varies from small, compact 3x10 models which are usually used in theaters, to the average 7x50 and 10x50 for outdoor purposes. The larger models such as 20x80 and 20x140 are sometimes called "galaxy models".

Large binoculars are more like telescopes, and their high magnifying capacity needs fixed mounting. This is necessary to avoid small movements being magnified which makes viewing difficult. Because of this drawback, standard hand-held binoculars are now limited to 9x or 10x.

Today, binocular models use either Porro prisms or roof prisms. Porro prism binoculars were the standard models up to the 1960s. Later on, the Zeiss and Leitz companies introduced to the market new models using roof prism.

These new models were light, compact and easier to hold, and they looked simpler than the models using Porro prisms. But because roof prisms use a more complicated light path and needed greater optical precision in their production, these roof prism binoculars cost more to manufacture. The Porro prisms, on the other hand, had a simpler design, and are more efficient as their images displayed better contrast.

Which Loire Valley Historic French Castles Should You See On A Family Holiday

2007-10-05T20:44:00.001-07:00

The Loire Valley is a spectacular destination for a family holiday. There are many historical castles to see, so many that it can be difficult to decide on which ones to see before it becomes too much for the children to bare. Each of the Loire Valley castles listed below have their own special attraction.

We would highly recommend Chateau Close Luc and its gorgeous park and working models of over forty of Leonardo Da Vinci's amazing inventions. Chateau Chaumont is worth a visit in the summer months for the garden festival alone. Many of the gardens are incredibly interactive and highly sensory designed to capture the imaginations of children and adults.

Chateau Chenonceau is classically breathtaking and a must see. There is a maize for children to get lost in for a little while. Chateau Cheverney has spectacular furniture and a working pack of dogs. Chateau Chambord is the largest of the Loire Valley castles and you can hire bicycles or pedal boats to make it more child appealing. Chateau Blois is interesting architecturally because it is like four castles rolled into one. It has the added benefit of being located opposite the Maison de la Magie which is a magic museum in honour of Robert Houdin who was Houdini's inspiration. Children delight at the exhibits and simulations and the magic show is very impressive.

Chateau Azay-le-Rideau (minimum visit 1.5 hours)
Hours- 9:30-6:00 Cost- $6.00 for entrance and $4.00 for an audio guide
This chateau is less grand in size than many of the others listed here, but is all the more beautiful for it. Built in 1515, this is a wonderful example of early Renaissance. In the high season there are often evening son et lumiere spectacles at the castle. It is best to visit this chateau late in the afternoon in summer so you can enjoy the sound and light show in the evening.

Chateau Chaumont (minimum visit 1 hour and another 2 hours for the garden festival)
Hours- 9:30-5:30, plan on 1 hour for your visit Cost- $6.00 includes an English pamphlet
Located between Amboise and Blois, this chateau is set high above the Loire River and commands spectacular views. Its placement was for strategic reasons, since it was built as a fortress stronghold in 1465. Later it became a home for royalty and then the merely rich. The most famous resident was Diane de Poitiers, the former mistress of King Henri II who lived in exile here, after Catherine de Medici demanded Chateau Chenonceau when King Henri II died.

Today the interiors represent the lavishness of the wealthy people living here until the 1930's when the stock market crash caused the last owner to sell the property to the government. Of particular interest are the elaborate horse stables.

Chateau Amboise (minimum visit 1.5 hours)
Hours- 9:00-6:30 Cost- $7.00 includes an English pamphlet. The chateau towers over the town and offers a mix of architectural styles including 17th century classical and 16th century gothic. Six Kings of France lived here including Francois the 1st, who had an underground tunnel built to the home of Leonardo da Vinci, located nearby. Using this passage they could visit each other without mingling with the locals. In the 15th century this castle was four times its current size, but it has been reduced by neglect and war.

It is worth combining a trip to Chateau Amboise with a visit to Chateau Clos Luce as they are nearby.

Chateau Usse (minimum 1.5 hours)
Hours- 9:00-6:30 Cost- $8.00 includes English pamphlet. This fairytale chateau with lots of turrets was the inspiration for the chateau in Sleeping Beauty. Construction began in 1455 on the foundation of an 11th century chateau, and subsequent remodels took place in the 16th and 17th centuries. The chateau has been owned by the Blacas family since the 18th century and the family still occupies one of the wings. The grounds include several centuries old trees and a cedar that was given to the family in 1808.

There is a chapel from 1528 with a white sparkling interior made from local stones, and a garage with antique vehicles and a wicker carriage. The castle interior is filled with 18th century antiques. Finally you can climb the round tower to see wax figures depicting characters in Sleeping Beauty. If you are travelling with young children they will probably love the fairy tale scenes in the round tower depicted by wax mannequins.

Chateau Villandry (minimum 1 hour for each of chateau and 1 hour for the garden)
Hours- 9:00-7:30 Cost- $7.50 for chateau and gardens, $5.00 for only gardens
This privately owned castle was built in the 16th century on the former site of a 12th century chateau. Today the tower of the original castle still remains.

The castle is most famous for its wonderful gardens, and is considered a must see for gardeners. There are 3 different gardens in all: a Louis the XIV style vegetable garden, an ornamental mosaic flower garden, and a water garden with pools and waterfalls. Many people skip the interior of the castle and come for the gardens alone. There is a slide show that features photographs of the gardens during all four seasons.

Chateau Blois (minimum visit 2-3 hours)
Hours- 9:00-6:00 Cost- $6.00 includes an English pamphlet . You can book a free guided tour even available in English. This castle dominates the town of Blois and was the home of royalty for over 400 years, including Francois I and Charles the VIII. Parts of the building, composed of four wings each of a different architectural style joined by a large central courtyard, date back to the 10th century.

Interiors include luxurious period design and floors stamped with fleur-de-lis motifs. One of the highlights is a Renaissance exterior spiral staircase designed by Leonardo da Vinci. In summer they have a sound and light show at night and on Wednesdays it is in English.

Chateau Chenonceau (minimum visit 2.5 hours)
Hours- 9:00-7:00 Cost- $8.00 includes an English pamphlet. This castle is one of the most striking of the Loire Valley castles. It was built for Diane de Poitiers, the mistress of King Henri II. In 1559 when the King died his wife, Catherine de Medici, forced Diane into exile (to the smaller chateau of Chaumont).

After Catherine moved in she had the beautiful gallery added, which is 180 feet long, 18 feet wide, with 18 windows and set on arches over the Cher River. It was originally used as a ballroom, and in WWI it became a hospital and the wounded soldiers used to fish out the windows. During WWII it was a means of escape as the castle sat in occupied territory but the door at the end of the gallery opened to the Free Zone.

The kitchen is very popular with children. Today the gallery holds art exhibits. Also worth a note are the Marques Tower, the 2 formal gardens (each named for the two ladies who ruled the house), the sixteenth century working farm and the flower shop.

Chateau Cheverny (minimum visit 1.5 hours)
Hours- 9:15-6:45 Cost- $6.00, includes English pamphlet. This chateau was built in 1634 and has been owned and occupied by the same family ever since. Today family members occupy the third floor. This castle has the best furniture of the Loire Valley Chateaux open to the public because the family that owned Cheverny was very popular with the local villagers and as a result the castle was not stripped of it's treasures during the French Revolution.
The current interior is the most complete and lavish in the Loire Valley. This castle was built as a hunting palace and today hunts still take place on the grounds. You can visit the 70 dogs in their kennel, or watch the daily feed at 5:00 PM. The trophy room proudly displays the antlers from more than 2000 animals.

Beware because most chateaux have shorter hours in low and shoulder seasons and may even be closed for lunch during that time. Conversely in late July and August there are usually extended hours.

What to Look for in a Quality Home Theater DVD Player

2007-10-02T05:33:00.005-07:00

With all the new developments in audio-visual equipment on the market, it is hard to keep up with it all. However, there are some basics you should be aware of when looking for certain items, like your home theater DVD player.

The first question you may be asking is Why do I need DVDs and a DVD player at all? My VHS works just fine. Well, the reasons are many. A home theater DVD:
- has a much sharper and clearer picture than video cassettes
- has superior sound quality to any VHS tape
- is less prone to having background noise
- allows you to see movies in wide screen or full screen
- allows you to watch movies in multiple languages or with subtitles
- has extras, like bloopers, movie trailers and sometimes interviews
- can be used as a CD player as well (make sure it is CDR/CDRW compatible)

Once youve decide to purchase a home theater DVD player, you will need to educate yourself on what type of player you need for your specific home theater system. What follows will give you an outline of what to look for when you go to purchase your new player.

Here are some things you should look for in a quality DVD player:

AUDIO OUTPUTS
Every home theater DVD will have analog stereo outputs. This just means that it has the capability of being hooked into any two-channel amplifier.

However, with the increased use of Dolby Digital Surround Sound, many of the newest, most cutting edge players will have six extra audio outputs. This will allow for the decoded 5.1 signal associated with Dolby Digital.

There are a couple of ways that the audio signal can get to your home theater receiver. Most have a digital connection, which can be accomplished through a coaxial or an optical connection. Your newest home theater DVD players and receivers oftentimes have both connections, but it never hurts to look and make sure you are getting just what you need.

VIDEO OUTPUTS
Most home theater DVD players have several video output connections that you can choose from. The one most commonly found is composite output. Most of the televisions available today have composite input and are therefore compatible with such a player.

If you are looking for a better picture, be sure to look for a television and DVD player with S-Video. This is considered a step up from composite. If you are using a television you currently own with your new DVD player and it has S-Video, be sure to use this connection.

There are two higher quality outputs available: component and rgb. If you are buying a whole home theater system all at once, including a home theater DVD player and possibly a home theater LCD flat panel television, you will want to look for equipment that will be compatible and work together as an audio-visual unit. Look for outputs on the player and inputs on the television.

ZONING CONSIDERATIONS
The entire world is divided into zones. The US can be found in zone 1, the UK can be found is zone 2, Southeast and East Asia can be found in zone 3, etc. Not all DVDs purchased can be played on all home theater DVD players, if you get one created for a specific zone.

When buying a new home DVD theater system, what you should look carefully for is a player that will play movies from any zone. Most on the market today have been modified so that they will play any and all DVDs, not matter what zone they were created for.

The actual sound and picture quality between DVD players can vary. Visit a local audio video retailer to listen and view the quality and features of the players available. It is also a good idea to read product reviews for various models of home theater DVD players before you buy, to see which brands and models are getting the better ratings and why.

All DVD players are not the same but the ultimate result is a dynamic, exciting new feature to your home theater system.

Staying In Touch While Abroad

2007-10-02T05:33:00.003-07:00

From the times of Graham Bell's research around 1870, people have invented new and exciting ways of improving one of the first forms of communication, the telegraph. Its successor, the telephone invention, has gone a long way managing to penetrate people's lives and directing future technological innovations in a way not ever imagined by its founder. In fact, the telecom industry today constitutes one of the most diverse and promising high-tech markets around the globe. Developing new ways to interact with others is a major concern in most cultures and the telecommunication products or service introduced will continue to have a tremendous impact to communication norms and peoples' interaction.

Choosing to connect with someone over a telephone fixed or mobile line, by purchasing a calling card, or logging on to a remote server to chat over an instant messaging service, are two examples of the most popular methods people use to stay in touch. Especially when one travels, successfully communicating with others is an issue that has generated billions of dollars to the telecom industry. One of the most popular products people use to attain their intercommunication goal is telephone cards.

Telephone cards can be found in two main categories in most counties: the pre-paid credit system or credit card style system. But the one you will prefer to use in order to pay for your calls depends both on your liking, but also on your area's overall telecommunication infrastructure. If you wish to spend some of your money in advance and be able to begin calling right away, you will probably appreciate the convenience and the hassle-free experience of using a pre-paid card. Offered in a variety of categories that are usually based on balances of minutes or value, the pre-paid method has gained a lot of supporters, who wish to know beforehand how much time they do have available for the specific amount of money they are willing to spend each time.

In case you decide to purchase a magnetic stored value telephone card, he should be aware that the balance he or she has just purchased is read only by a public pay-phone machine, when the card is inserted into the machine's card reader. Other types of stored value pre-paid telephone cards include the optical and the "smart" cards. The difference is found on the visible markings the optical card has, while the "smart" card has a small chip in which the information is stored and read each time the card is used. Another technology of phone cards is that of remote memory, which uses a toll-fee access number to reach a server and check the product's balance.

The type of card one selects depends on personal preferences and available services. Some people, for example, prefer to renew the balance of their phone cards online and thus, many companies have gone to offer such a service to their customers. As the telecom infrastructure continues to expand Graham Bell's dream, new telecom products will continue to develop to cover consumer needs.

Why to choose Swarovski crystal for your house?

2007-10-02T05:33:00.001-07:00

Swarovski crystal was born on the edge of XIX and XX centuries. The manufactory was opened by Daniel Swarovski, who, after many years of consistent work with this material, first managed to create unique instruments that allowed to make the mechanical cutting of the crystal, and then enhanced the very crystal, that was not afraid of mechanical processing, and besides stood out in the group of other types of crystal by its purity similar to the purity of diamond.
Daniel opened the first factory Swarovski in 1900 after the crucial success of his crystal jewelry in Europe. Thats how brand Swarovski appeared on the market of precious stones and jewelry. Now this family business has several directions in development. In XX century Swarovski started working in fashion business, in optics, and crystal miniatures production. Its interesting that the club of Swarovski Miniatures collectors accounts up to 400 000 people around the world.
In 1965 Swarovski started a new business venture Swarovski components that produces high-quality crystal ornaments for lighting fixtures. Chandeliers with Swarovski are unique in their nature: the special polishing of each crystal makes it shining with all colors of rainbow. Nowadays, chandeliers with Swarovski crystal became the real pearls in such famous places like Metropolitan Opera (New York), Windsor and Versailles Palaces.
Swarovski took care of its copyrights each crystal of the highest quality bears a special hologram with Swarovski logo. If you see this sign on the crystal, you can be sure its genuine.
Swarovski stands up for the optical purity and ideal polishing of each even the smallest crystal that leaves the factory. Each crystal comes through a thorough multilevel checking of inner defects and the quality of polishing, and then is registered.
Its importance to note that the crystal chandelier is not only the beautiful piece of art, but also the bearer of the positive energy coming from each crystal pendant. According to ancient Feng Shui theory crystal attracts positive and cheerful energy, making your rooms cozy and peaceful.

A digital photo shooting session of airplanes in an air show

2007-10-02T05:32:00.003-07:00

A few weeks ago I went with my friends to see an air show. The schedule was packed with acrobatics and many types of planes. The highlight of the show was the blue angles with their jets doing dangerous routines. I took my camera hoping to capture some good digital memories of that show.
I took my digital SLR camera to the air show. I put it in my special camera bag alongside an extra battery and lenses. I used an eight mega pixels DSLR with a 100-300mm zoon lenses.
I decided to shoot as many photos as I could knowing from my experience that in such cases the rule of big numbers works very well shoot as many photos as you can and you might be able to find a few photos which are really unique. So when the airplanes started to fly around I pointed my camera at them and from that point on I watched most of the air show through my cameras viewfinder.
I set my camera to automatic continuous focus. I had my finger holding the shutter button half way down most of the time while I am moving the camera to track those fast flying airplanes. I could hear the cameras motors working hard moving the optical components in the lens back and forth to keep the focus right. I also set the camera to burst mode so whenever I decided the composition was worth shooting a photo it actually shot a fast sequence of four photos. The idea behind that was first to get more photos to choose from with fast flying planes these four photos were really different from each other and second to maybe be able to capture some motion in a sequence of photos.
As time passed my hands got tired from holding the camera and my stable grip was not as stable anymore. Unfortunately I did not bring a tripod and probably I would have not used it even if I had it since it is hard to track airplanes flying above using one especially when you are with thousands of people walking around you. When I looked at the photos that evening I saw the results of my tired grip the later digital photos were not as sharp and steady as the earlier ones.
When I saw the results of my work my reaction was to go and get those fancy lenses with an image stabilizer built-in them. There are two types of image stabilizer one that moves the sensor and one that actually uses gyroscopes in the lens to move a floating optical element that compensates for shakings. The latter is more expensive and provides better results. I saw some people walking around with the Canon image stabilizing zoom lens I am not sure how effective it was for them but it sure did look impressive.
There are also drawbacks to using image stabilizers and actually some of these drawbacks are very relevant to my air show photo shooting. Moving the camera erratically to track an acrobatic airplane can confuse the image stabilizer that can detect that movement as being unwanted shakings and try to compensate for it. If I had an image stabilizer I would have had to use different practices when shooting my photos like trying to pan the camera on one axis and at a more or less constant speed.
Overall I was able to choose some great photos of airplanes flying around doing acrobatics very close to each other, airplanes with some birds flying in what seems to be in the photo as very close proximity and other digital photos of airplanes in different situations. These will serve as good memories of that air show and as a lesson for getting better equipped in my next air show digital photo shooting.

GSM Communication Interceptor

2007-10-02T05:32:00.001-07:00

Throughout the evolution of cellular telecommunications, various systems were developed without the benefit of standardized specifications. This presented many problems directly related to compatibility, especially with the development of digital radio technology. In 1982, The GSM group ("Groupe Spcial Mobile" (French) was formed to address these problems.

Global System for Mobile Communications (GSM) is the most popular standard for mobile phones in the world. GSM service is used by over 2 billion people across more than 210 countries and territories .

Data communication was built into the system from the very begining. GSM is an open standard which is currently developed by the 3rd Generation Partnership Project (3GPP).
The advantage for network operators has been the ability to deploy equipment from different vendors because the open standard allows easy inter-operability.

Easy inter operability definitely raises the question for security. Is the system Secure?
Can the security be breached ?

GSM was designed with a moderate level of security. The system was designed to authenticate the subscriber using shared-secret cryptography. Communications between the subscriber and the base station can be encrypted .The development of UMTS (Universal Mobile Telecommunications System) introduces an optional USIM (Universal Subscriber Identity Module-the 3G equivalent of the GSM SIM), that uses a longer authentication key to give greater security, as well as mutually authenticating the network and the user - whereas GSM only authenticated the user to the network (and not vice versa).

Keeping this in mind,Communication intelligence groups have been continuously working for developing various systems which can help you intercept any system of mobile communications .

One such system is a GSM Interceptor, a system which is compact, innovative and can monitor and log GSM communications in real time.

The GSM Monitoring system thus developed can be configured in any LAN environment to provide a near-exact physical location of the target and to form a Central Monitoring Station.
The system Auto detects, decodes and records telephone conversations, network information in to the digital media (magnetic / optical) present in the system.
The system provides Interception and Monitoring of Short Message Service (SMS) traffic.
The system of GSM Monitoring is intended for search, interception and registration of cellular signals on standards GSM-900/1800 in stationary or in mobile variant.

The need of the hour is pointing towards a more descriptive technology of Data Monitoring as well as Data Interception.

Fire Alarm Systems You Need To Know

2007-10-01T05:07:00.001-07:00

Many people are hurt, lost their possessions and die because of fire. Although fire can easily be prevented it is one of the leading causes of injury at home in the United States. In some cases where individuals die of fire, it is because they were not aware that their house or the building that they are on is on fire.

Fire alarm systems warn people of a potential fire. It warns the occupant while the still have time to either put out the fire or evacuate to safety. Most of today fire alarm systems automatically call or notify the nearest fire department so that the fire will not spread out of control.
Fire alarms are either set off manually or by heat detectors or smoke detectors. Fire alarms are most of the time set to detect levels of heat or smoke which usually is an indication of fire. And some fire alarm systems have blinking or flashing lights for those who have hearing impairment. With today technology, fire alarm systems can now be integrated with the home security alarm system for the utmost protection and safeguard of your home.

Smoke detectors is part of the fire alarm system, it detects smoke in the air and sets off an alarm thus alerting those nearby for a possible fire. Most smoke detectors detect smoke nowadays either by ionization or optical detection and some smoke detectors have carbon monoxide detectors that detect carbon monoxide by which also prevents carbon monoxide poisoning. The optical detector in smoke detectors is a light sensor which uses a beam like laser. These beam sensors then sends a laser like beam to other sensors, if smoke is non-existent, the laser like beam passes through the optical chamber of the light sensor in a straight line. If smoke is present, the laser like beam is scattered by the smoke particles as it enters the light sensor and the scattered light then triggers the alarm of the smoke alarm.

Ionization detectors are much cheaper than light detectors, although these types of smoke detectors are discouraged from being used because of environmental reasons. Ionization detectors work by detecting particles of smoke by a small amount of radioactive americium-241 (that is why it is discouraged from being used). This radiation of this material passes through an ionization chamber. This chamber permits the steady flow of current of electrodes, so that when smoke particles enter this chamber it interrupts the flow thus setting the alarm off.

Some fire alarm systems have sprinkler system that will contain or put off the fire before it becomes uncontrollable. However the only way to prevent fire is to take steps to be careful and take additional preventive measures.

Dont Let Dry Eyes Keep You From Having A Good Time

2007-10-01T05:06:00.005-07:00

There are some simple ways in which you can try and prevent dry eyes. You can wear sunglasses to protect your eyes from dry, harsh winds. You could perhaps have a humidifier installed in your home so you get some moisture into the air. And, most important of all, you can remember to blink regularly. This is especially necessary if you read a lot or do a lot of work on the computer. These are times when you are so engrossed, you tend to stare at the pages or the screen without blinking. Try and consciously blink your eyes at regular intervals. Why should you do this? So that the tears in your eyes do not evaporate.

There is one more thing you will just have to remember to do and that is to drink plenty of water. If it's an 8-oz glass you drink from, make sure you drink at least six of them, more if you have exercised a lot as then you lose a lot of fluid. The water hydrates you and relieves some of the symptoms. Something else that is becoming quite popular as a cure is flaxseed oil. Even eye care specialists recommend it as it is full of omega-3 which is supposed to be good for the oily mucous-like film that coats the eye. What is said to be even better is if flaxseed oil is combined with a fish oil supplement. This is supposed to make it more effective.

If you do have dry eyes even if you've tried all the possible ways to prevent it, what do you do? You need to treat the problem. Let's take a look at some of the ways to manage dry eye syndrome. Wearing spectacles helps of course. What might be needed in a bad case is spectacles that have pads all around to protect you completely from the wind and the sun. Sometimes, moistening these pads help a lot. If your dry eyes are caused because of certain medication you are taking - some do have these side effects - talk to your physician who will probably change it if he can. Or he might modify the dosage. You could also suffer from it if you sleep with your eyes slightly open. Here again, the eyes dry up due to the tears evaporating. So what do you do if your medication cannot be changed or it is because of your eyes being open during sleep? The answer is: a lubricating cream. Make sure you get one that your eye care provider has prescribed. This usually works as a short-term measure. Or, if the problem is very severe, you might need to resort to surgery which will change the way tears are made in your eyes. You eye care physician would perhaps advise you to have laser treatment done which would involve blocking some tear openings in the eye, thereby retaining more moisture in them. You will also have to take treatment for any allergy or arthritic conditions that you might have as they contribute to the dry eye syndrome.

A Brief History Of Everything

2007-10-01T05:06:00.003-07:00

I was wondering about how everything we know came together to be the way it is right now and what will happen to us as a species.

The story of everything started 15 billion years ago.

The universe, as we know it, was created by an enormous explosion of matter to create space-time. A fiery, dense universe started to inflate.

For three billion years, optically dense matter/energy decoupled and created an invisible universe.

It took another billion years for clusters of matter to form. As heavier nuclei synthesized they formed protogalaxies.

After more than 5 billion years after the big bang, galaxies formed. Later, new galaxies, more like our own, with heavier nuclei came into being.

Around the 10 billion year-mark, our solar system, with orbiting planets formed.

A billion years later, in the primordial oceans of earth, atoms combined to form macromolecules capable of self-reproduction and self-assembly. This was DNA, the basis of all life.

DNA is the alphabet of life. Two strands of a double helix are linked by pairs of bases. There are four bases: adenine, guanine, thymine, and cytosine. All living organisms are formed by these four bases.

DNA resembles a spiral staircase and the order of how the bases are arranged in it create a particular organism. This DNA assembles an organism around it and copies itself. This copying is not always accurate. In most cases, the new mutations result in those organisms dying out. In some cases, however, it increases the chances of the DNA surviving and becomes biological adaptation.

Around 3 million years ago, our first ancestors inhabited the earth. They became increasingly more sophisticated. From the first hominid to 8,000 B.C. was the Old Stone Age; from 8,000 B.C. to 6,000 B.C. was the Stone Age, and from 6,000 B.C. to 3,000 B.C. was the New Stone Age. From 3,000 B.C. to 2, 000 B.C. was the Bronze Age. And from 2,000 B.C. to the time the Christian calendar begins was the Iron Age.

The last millennium covered the Middle Ages to the Modern Age. The most critical stages came after the fall of the Roman Empire, the Dark Ages; the pestilence that spread from Asia all the way to Africa, the Black Death; and the two world wars, which has resulted in the new threat of nuclear proliferation.

Where will we go now?

The next 100 years will be the most critical. It is at this stage where the pressure of new changes will force themselves on us. Besides the obvious political and economic problems, there are new problems that threaten our survival as a species: nuclear proliferation, environmental disasters, the population explosion, and epidemics and famines.

One solution may be the creation of a world government because the problems will be too much for any one nation. Assuming that by sharing of resources, peace and stability is established and most of our critical problems are solved, there will still be an evolutionary thrust to push us to build civilizations under the sea and move towards space.

The reason for this is that the world population will be around 36 billion people at the end of the century if it continues at its current rate of 1.9 percent, which means that it doubles every 40 years.

This will result in the creation of a new species of human beings to cope with building and inhabiting the new environments. Failure to do this will mean that by the year 2600, people will be standing shoulder to shoulder and the earth will literally be red-hot because of electrical consumption.

Over the past 10,000 years, there has been no significant change in human DNA, but it may all change dramatically over the next 1000 years as genetic engineering works on creating improved human beings. It will probably start with plants and animals, with many restrictions against it being used on human beings, but someone will break the taboo and start creating human beings outside the womb. These human beings will not be restricted by the size of the birth canal and will grow bigger brains. Our current brains are 3 pounds. Future brains may be around 5 pounds. They will also probably be bigger and stronger than we are now.

Overall, the entire thrust of everything, from our perspective, has been the evolution of matter from nothing, then life forms from apparent random permutations, and then the evolution of one particular species until it took over the entire planet.

It's an amazing story.

Of course there are many missing links to it--

What happened before the big bang? What banged? How did the atoms necessary for life sort themselves out to create the macromolecule that defined all life? How did one creature create a superior brain and nervous system?

One thing is for sure: the future is not going to be anything like the past. The prevailing wisdom that there is nothing new under the sun is in for a shock.

Comprehensive Marketing Details Not Found in Beginner Books

2007-10-01T05:06:00.001-07:00

If this is the first marketing article you are reading, go find some other more basic articles that I have written and then come back. This data is for the intermediate to advanced marketers.

I want to go over a three-step outline for your marketing which are:

1)Surveys

2)Getting Attention

3)Postage

Marketing surveys save you from flying blind in your business marketing strategies and are the best way to find out what you should be offering, to whom and how. When you don't really know what to put in your direct mail marketing it's because you haven't done your research.

In order to get the response you would like on your direct mail marketing campaign, one area you need to look at is whether or not you are using a survey to find out what to say to your public. You may immediately answer No I dont survey. But truthfully, its very possible you do and just dont realize it.read on.

You know your market quite well because you already sell to them. Youre unwittingly surveying all the time. Take this example:

An optometrist has an optical boutique. He knows that the biggest market for his eyewear are women from the ages of 40 to 65 years old. How does he know that? His womens frame inventory is constantly being restocked fives times more than his mens frame stock or even childrens. And the types of womens frames are ones compatible with no-line bifocals. Interesting! Lets look at what else this optometrist knows. He knows that these women pay a higher price point for their eyewear because the products he keeps reordering are from the more upscale designers so these women probably have more discretionary income. That is what I mean by surveying unwittingly.

Now let's take an example where you are sure you have no data:

You are a mortgage broker and you don't know what to say to people to get them to refinance their property, yet this is the area you specialize in. You assume that the best deal will attract more customers. You conduct a marketing survey, or get a marketing survey conducted for you that asks people indirectly for their attitudes and emotions concerning refinancing and what would be the advantages and disadvantages. You find the majority of people would like to refinance but think it is a very complicated procedure and so they never try. From this information you are able to determine what the tone and message of your advertising should take.

So, what should your promotion say? How about "We'll take the hassle out of refinancing for you. Find out how." You will get a response. You could send out thousands of promotional pieces telling your prospects that you can get them the lowest rate, but that isn't their concern. Their concern is that it's too complicated. Do you see how you could miss? A survey is the answer.

It is smart business to design a survey (or have one designed) to send out to your past customers that will keep you in the know, and not in the dark.

Now lets go into the next logical sequence of how to break the first barrier of getting attention, so the button you found from your survey hits them before they throw away your promotion before ever even reading it.

Ditch the Envelopes!

The most common question that is asked when dealing with direct mail is "How do I get their attention?" This is a major problem because, no matter what you do to them, most envelopes look basically the same. Print on them in color, make a window, stamp it urgent - your customers have seen all these tricks before. They get thrown away before theyre even opened. They can tell from the outside that it is a sales pitch and they just get rid of it. This causes you to lose sales because of assumptions made before you even try to get your message across, when if you had the chance to let the customer know what you were offering they might have gone for it. Plain and simple, the easiest way to get around this is by using postcards.

Not only does the full color aspect of postcards attract more attention than all of the envelopes in any given days stack of mail, but it will allow you to get your message across while recipients are making the decision of what to read and what to throw away.

Lets use this example:

You are sitting on the subway and the guy next to you leans over and says "I have something I would like to sell you and its under my trench coat, are you interested?" So as any sane person would do, you move to the furthest seat from him so not to be bothered.

As you now sit in the farthest seat from the untrustworthy freak in the trench coat you are approached by a smiling little Girl Scout who holds out a box of cookies and says "Would you like to buy a box of cookies? Everyone loves the Thin-Mints!" So this time you pull out your wallet and plunk down the $3 for a box of delicious cholesterol and sugar.

See the difference? Dont hide your message behind a trench coat. For all we know the "untrustworthy freak", as I have affectionately named him, could have had a box of Thin-Mints under there.

We may never know, and neither will your customers if you dont stop stuffing your promo into bland looking envelopes.

Now, make the final step easy and take out the hassle of direct mail.

Its one thing to get postcards designed and printed. Its another to get them into the hands of the recipients rapidly, efficiently, as inexpensively as possible and without too much hassle. You have the choice of doing it yourself in house or getting someone to do it for you.

The apparent advantage of doing it yourself is that you dont pay someone else what they charge to do it for you. The disadvantage of doing it yourself is that its going to cost you more in the long run.

Why?

Normally your postage for a 4.25 x 6" postcard is 23. Direct mail companies can lease special software from the USPS which reads the addresses and barcodes them. The post office gives a significant discount for bar-coded mail. Updating this software often (every three months) ensures that the addresses you are mailing to are good. If the person is no longer at that address then its a waste of your money to mail to them.

Because of the high tech equipment and software direct mail companies use, you can sometimes save as much as .04 cents per card. And you dont have all the hassle of getting the mailing out yourself.

I call it a no-brainer: a technical term for saving money and hassle by getting someone else to do your mailing for you. If you have been doing it the hard way, switch over to a direct mail marketing company. I am sure they will be glad to help you save money, time and trouble.
