User interfaces and accessibility are some of the most important aspect of an application. It can have a million features, it can do a thousand things once, but if it doesn't look quite right then it will be a disaster. Take Linux for example. This open source (free) operating system has been around for quite a while, and it has been very appreciated for its stability and speed. However, in its earlier days it lacked a user interface, which made it very unattractive to the general public. While a few years back Linux was used only by system administrator and computer freaks, Microsoft's Windows was all over the place, pumped up by its friendly user interface, even though it had a lot of bugs and was very unstable. Today's things are quite different. People have learned from their mistakes and now, most operating systems, including Linux, use a graphical interface and are very user-friendly - things that in the past you could do by writing lines and lines of instructions, you can now do with a few clicks. This major improvement has brought in a whole new class of users, and the popularity of this operating system has increased considerably.This is why the user interface matters a lot to the average computer user, and icons are one of the most important issues at matter. But why use icons and not plain text? Well, icons are visual mnemonics, that is, they are easier to remember. We see an icon a few times (or maybe once) and we "learn" it, and afterwords we associate the image with a certain action. The same thing happens with text, but it's a lot faster to "read" an icon than it is to read a text, which makes icons a lot more recommended. Furthermore, adding icons to the important components of your application will sometimes save you from the frustration of answering the users who are not very familiar with the application and have trouble finding out how to use a certain feature. For example adding a question mark icon next inside the help button will make it easier for users to figure out where they can get help.Today's developers know that users will learn how to use a certain application a lot faster if its interface looks like the applications they are already familiar with. Take for example a Mac: can you see how all applications look pretty much the same? So it's really easy to start using new applications, and you don't have to read the manual to see what each button does, because most likely you'll figure out that on your own. But there are two sides to this: if all applications look more or less the same, where is the uniqueness? Then again, if the application is totally unique, users might find it difficult to get acquainted with. So the best way to go is to use an interface that combines both these rules - not an "average" looking user interface, but also not a totally unique one. It's easy to get stuck with this idea, but this is where icons come in.Icons are the easiest way to differentiate your application, while still keeping a note of familiarity. Most developers have found it very efficient to replace the operating system's stock icons with their own custom-made icons. How? Well, start with the little things. Try adding shadows to icons, or maybe apply different effects (emboss, blur, add a border, etc.) using a graphics editor. Another approach is to change the icon's colors. Make them all blue, yellow, or some other color you might think it would look great with the rest of the interface. A toolbar with enhanced, yet similar buttons (for example replacing the New, Open, Save, Print, Cut, Copy, Paste icons) really improves the overall interface. After replacing the icons, it's a lot easier to make the next step and start changing colors.But what to do with these old-fashioned users that like to keep it simple? How about people with special needs, who might have problems reading small texts or seeing some colors. Also, there must be a way for all the people - and it's really a mystery here - who like the same old icons and colors on all their applications. Fortunately, the answer is simple: different application skins! It's a good idea to have a "standard" skin for the users who like to keep it simple, offering the basic features in a really easy to use manner, and then to create a few more enhanced skins for the people that like different interfaces - big fat buttons with shiny icons for the main applications features, or perhaps lots of toolbars with many buttons for advanced users. Again, the easiest way to creating new skins is changing the icons and colors. You don't really have to change the layout of the application and move all the toolbars/buttons/windows around, for it might require sometimes too much work. But replacing icons is really easy. Voila! You have a new skin!Today's computer applications are focusing more and more on graphics, and especially icons, while text interfaces are becoming less popular. The modern applications' interfaces use icons and text as well, but paying a special attention to icons. This way it's a lot easier for users to learn how the application works, so therefore they will accomplish their tasks quickly. An intuitive interface and standard behaviors don't require much explanation, and a well-designed application must not get into the user's way, but must provide fast access to its most important features. This is the general rule which brought Microsoft millions and millions of dollars for it's main product - the Windows operating system - so why shouldn't we follow their example?

The beginning of generation codes used to program computers, was called machine language or machine code, it is the only language a computer really understands. It is a sequence of 0s and 1s that the computer's controllers electrically interpret as instructions. The second generation of codes was called assembly language. assembly language turns the foreign language of 0s and 1s into human words like 'add'. Assembly language is always translated back into machine code by computer programs called assemblers.The third generation of code, was called high level language or HLL, which has human sounding words as well as words put into sentences. In order for the computer to understand any HLL, a compiler interprets the high level language into either assembly language or machine code. All software programming languages need to be eventually translated into machine code for a computer to use the instructions they contain.As the user you do not see the code used to create computer software programs. However, you do use the results and the end products of software programming which are soft programs that are easy to use by the consumer. Below is an article discussing the history of software programming of Computer Chess and the lives of the software programmer behind one of your favorite software programs.Dr. Dietrich Prinz wrote the original computer chess program for a universal functioning computer. The program was released in November 1951. Previously, special purpose machines which were designed only for playing chess had been invented, but Prinz decided to invent a program that could be played on any general computer. Since computers of the 1950s had very little memory power compared to todays computers, his program could only examine every possible move until a solution was found which took an average of fifteen minutes (a move that can be accomplished by a modern computer in a fraction of a second!) However, for its time this was considered a miracle.Dr. Dietrich G. Prinz was born on 29 March, 1903. He was educated at Berlin University, where his teachers included geniuss Planck and Einstein and graduated with a Ph.D. in Philosophy. He left for England in 1935 where he began working at Ferranti Ltd., a major computer business. He soon became the companies head programmer and in 1957, after his original chess program, a full-fledged chess program introduced by Bernstein for an IMB. In 1983, a chess program called Belle was designed by AT&T and became the first to reach the U.S.A. Since, Chess programs have become widely popular to a large group of people, including mater chess players as well as novices.
