I once created a notepad-like editor. It is possible with this editor to write Russian text on a western Windows without using a Cyrillic keyboard in front of your computer.
This software is equipped with an on screen Russian keyboard which is situated under the text field of the notepad like editor. The keys on the screen based keyboard is displayed with both Latin and Cyrillic characters. The Cyrillic characters are displayed in red and the Latin are displayed in Black.
One day, I got an angry e-mail from one users of the product.
He wrote
Don?t you know that ?so and so? many people have one form or another of colorblindness. I can?t read the Russian character in the keyboard. Could you change the color of the letters?
At that time I used a bright red color for the Russian characters and the keys were in gray.
I have since of course changed the color. Now I use a more darker red color to represent the Russian letters.
I myself don?t suffer from this problem, but I while ago I surfed around on the Internet and found a cool website that is all about colorblindness and remembered the e-mail and the adjustment I had to made to the Russian editor.
On that site is a tool which you can use to see how your website would look if you were a colorblind person. The URL is http://www.vischeck.com/vischeck/vischeckURL.php
You just type on your URL and you can then see how your web page will look for a person with different forms of colorblindness.
I learned there that there are different forms of colorblindness.
In fact the term colorblindness is a little misleading, because most people with color blindness don?t see the world in black and white. They can see colors, but not all colors. Total colorblindness is very rare. Color deficiency is a much better term to use.
Different form of color deficiency affects large number of people.
Colorblindness is in a large extent a gender problem, because it is affecting males much more often than females.
Here are some facts, I?ve learned!
About 8 % of males have some sorts of color deficiency.
For females this figure is under 0.5%.
On the http://www.vischeck.com/vischeck/vischeckURL.php you can check for 3 forms of colorblindness:
Deuteranope (a form of red/green color deficit)
Protanope (another form of red/green color deficit)
Tritanope (a blue/yellow deficit- very rare)
There are more types of colorblindness, but these tests will cover the most common types.
They also offer the same color blindness function with a plug-in software for Photoshop.
Colorblindness is not a problem if the text on your web site is in blank on a white background.
But, if you mix text with color on a colored background, this can create a problem with your web site for many viewers.
It is more common to make mistakes if you mix the wrong colors on external images and banners that have text in one color and the background in another, than to mix the wrong color with raw text.

Cleaning Your Computer Will Help It Last Longer And Work Better
Cleaning Your Computer Will Help It Last Longer And Work Better
by: Scott Dary
To clean your mouse ? The trackball can pick up dirt and dust from your desk and mouse pad. Also, the wheels that the trackball come in contact with get dirty and need to be cleaned. If you notice your mouse "doesn't work right", it may be time to clean it. First, turn your PC off. Turn your mouse over and you will see the ball sticking out of a cover. Look at the arrows on the cover and turn it in the indicated direction to open it up. Don?t worry about anything falling out. The only thing that comes out is the ball, and maybe a little dust, and you want to take that out anyway.
You can clean the ball with alcohol if it needs it, but usually just wiping it off will work. A cotton swab dipped in rubbing alcohol works well for cleaning the wheels. When you?re done, drop the ball back in and put the cover back on. If cleaning it doesn?t help, it may be time to replace...

Pain Relief from Neck and Shoulder Pain My Top 5 Favorite Ways
Pain Relief from Neck and Shoulder Pain My Top 5 Favorite Ways
by: Wendy Young
When you are experiencing neck and shoulder pain at your computer, there are simple actions you can take to help you feel better.
It is very important to understand how your body reacts with the design of your computer work area. Of equal concern is choosing products to help you rather than create additional pain. It can be just as simple as adjusting or rearranging your equipment and furniture.
Monitor Height Placement
If you bend your neck back to see the monitor, it is too high. If you bend your neck down, your monitor is too low.
Let your head rest naturally and it will tilt slightly forward. You have left the office too many times with sore muscles!
When looking straight ahead, your line of sight is the imaginary horizontal line from your eyes to the screen. Your eyes naturally gaze down 15 ? 20 degrees below your line of sight. Adjust...

Keyboard Power: Using Your Computer Even if Your Mouse ?Dies?
Keyboard Power: Using Your Computer Even if Your Mouse ?Dies?
by: Ismael D. Tabije
There are various accessories that could help operating a computer easier. The mouse is just an example of an accessory which makes navigation simple with just one click. However, most of these accessories have short ?lifespan? and can be considered disposable. This is when the accessories can become bothersome.
What are you to do, when in the middle of an important document, your mouse decides to ?die?? Would you worry? Would you panic and run to the nearest store? What if it?s night time and the stores are closed and you are rushing up your work?
On your keyboard, immediately press CTRL + S simultaneously to save whatever it is you?re doing. That way, you don?t lose your work. This is a common and one of the most familiar tasks without using the mouse. If the mouse is not functioning and you need to do something important but you don?t have the time to...

Linux Terminal Control Sequences
Linux Terminal Control Sequences
by: Sitecritic .Net
Linux terminals share alot in common with their primitive ancestors such as vt100 like consoles. These early devices is capable of sending sequences that signaled events outside of the normal flow of typed characters, such as escape, tab, linefeed...etc. Linux uses CTRL key to send out these out of band signals.
This article summarises many of the commonly used control sequences that are used in all Linux terminals.
CTRL-C
This is the most commonly used sequence. In the bash shell, CTRL-C will terminate any currently running process and return you to the bash prompt. For example, if you accidentally run a command that does not stop, use CTRL-C to cancel the command.
CTRL-D
Many Unix commands read their input directly from the keyboard. An example is the WC command. WC counts the number of lines, words and characters that a user types in from the keyboard. So if you...

Computer Components for Idiots
Computer Components for Idiots
by: Ron King
There are many fancy add-ons for computers, but the basic components of the computer are simple and universal. If 1 of these main components is missing, it?s not a computer.
The 4 essentials of every computer system are: a motherboard, a Central Processing Unit (CPU), memory, and a hard drive. These components are installed in a case to which are attached a monitor, a keyboard and a mouse. That?s your basic computer.
Mother WHAT?
The motherboard ("mobo" for short) is the foundation. Everything attaches to the mobo -- the CPU, memory, hard drive, monitor, mouse, keyboard, add-on cards, even additional peripherals like printers, scanners, and speakers. The motherboard is like the nervous system and skeleton of the human body -- it provides support for the internal components and also passes information between the computer parts.
CPU
If the motherboard is the nervous system,...

Mouse Hunt ? Not the Movie (Choosing the Perfect Mouse for Your Computer)
Computer Mouse ? it?s something you wouldn?t run away from. Instead, it is the one thing you would search for. In fact, every body is in search for a good one. And it has actually become a not-so-easy task to ?hunt? for a good mouse ? for your pc.
What do you look for, when you say ?good computer mouse?? Often, when you buy a whole pc set, a mouse is already included. But there are others who still search for a good one.
In choosing a mouse, you must consider its compatibility with the pc and of course, with you, the user. As the technology advances, there are many types of mice to choose from ranging from mechanical (the ball-inside-type) to optical (ones that use laser to detect movement). Check the connectivity, as there are different mice with different connectivity...
