Linux is a free and efficient open-source implementation of Unix. Originally developed in 1991 by Linus Torvalds, Linux now runs on most computer platforms and is available for all major microprocessors. Several large software companies now sell their own version of the OS, but it is still freely available for those who want to modify it. However, any modified version that is redistributed must also be freely available.

When you type regular letters, numbers, and characters from your keyboard into the body of an HTML document, they show up on your Web pages just as you typed them. But things aren’t so easy in non-English speaking countries (and such places do exist – honest). Languages such as French, German, and Icelandic often use characters that are not found on your typical keyboard. Even in English, accents can distinguish a “résumé” from a “resume.”
So how do you make special characters and accented letters show up on your pages? You use a special set of codes called character entities, which you insert into your HTML code and which your browser will display as the corresponding symbols or characters you want.Continue Reading “Write Symbols and Special Characters in HTML” »
In early 1998, Netscape announced that it would release the source code of its next-generation browser as a part of its open source strategy. The source code contains the programming elements that make up the Communicator software application. It is not a compiled program and thus cannot be used by traditional software end-users. Mozilla, as it is called, was released as C++ source code and caused a flutter of excitement in part because of its implementation of the World Wide Web Consortium’s standards, eXtensible markup language (XML), and the resource description framework.

Python is an interpreted, object-oriented programming language that runs on several operating systems, including Unix, Windows, OS/2 and Macintosh. The language is relatively easy to learn, and can be used for developing apps, or for more mundane tasks such as system administration, code generation and graphical user interfaces. Python was created by Guido van Rossum, whose favorite comedy group was, you guessed it, Monty Python’s Flying Circus. Python is copyrighted, but the source code is freely available and can be commercially re-sold.
