Licenses

Published software should be free software. To make it free software, you need to release it under a free software license. We normally use the GNU General Public License (GNU GPL), but occasionally we use other free software licenses. We use only licenses that are compatible with the GNU GPL for GNU software.

Documentation for free software should be free documentation, so that people can redistribute it and improve it along with the software it describes. To make it free documentation, you need to release it under a free documentation license. We normally use the GNU Free Documentation License (GNU FDL), but occasionally we use other free documentation licenses.

Gnu’s Not Unix!

GNU, which stands for Gnu’s Not Unix, is the name for the complete Unix-compatible software system.
So far we have an Emacs text editor with Lisp for writing editor commands, a source level debugger, a yacc-compatible parser generator, a linker, and around 35 utilities. A shell (command interpreter) is nearly completed. A new portable optimizing C compiler has compiled itself and may be released this year. An initial kernel exists but many more features are needed to emulate Unix. When the kernel and compiler are finished, it will be possible to distribute a GNU system suitable for program development. We will use TeX as our text formatter, but an nroff is being worked on. We will use the free, portable X window system as well. After this we will add a portable Common Lisp, an Empire game, a spreadsheet, and hundreds of other things, plus on-line documentation. We hope to supply, eventually, everything useful that normally comes with a Unix system, and more.

GNU will be able to run Unix programs, but will not be identical to Unix. We will make all improvements that are convenient, based on our experience with other operating systems. In particular, we plan to have longer file names, file version numbers, a crashproof file system, file name completion perhaps, terminal-independent display support, and perhaps eventually a Lisp-based window system through which several Lisp programs and ordinary Unix programs can share a screen. Both C and Lisp will be available as system programming languages. We will try to support UUCP, MIT Chaosnet, and Internet protocols for communication.

GNU is aimed initially at machines in the 68000/16000 class with virtual memory, because they are the easiest machines to make it run on. The extra effort to make it run on smaller machines will be left to someone who wants to use it on them.

Why Linux?

I guess people won’t switch to Linux because it’s free (as in free speech, they probably don’t care) or because it’s free (as in free beer, they probably think they didn’t pay for Windows), but because they see new, great features that Windows doesn’t have. So here are a few reasons why Linux rocks!

Oh, and before that, if you’re already a Linux geek, you might want to read this

What is Open Source?

Open Source refers to the fact that the source code of Free Software is open to and for the world to take, to modify and to reuse. The precise meaning of Free Software is spelled out in the Debian Free Software Guidelines or the Free Software Definition while Open Source is defined officially by the Open Source Definition. Open Source and Free Software refer to, originally the same (around Feb 1998), but now different but largely similiar, set of software, but they emphasize different rationals.

Stallman: If you want freedom don’t follow Linus Torvalds

“Please don’t call GNU ‘Linux’,” says Richard Stallman, the founder of the Free Software Foundation. In this interview, he also asks readers whether they will fight for freedom or be too lazy to resist.
