GNU is the only operating system developed specifically to give its users freedom. What is GNU, and what freedom is at stake?

Wat is GNU?

GNU is an operating system that is free software—that is, it respects users' freedom. The development of GNU made it possible to use a computer without software that would trample your freedom.

We recommend installable versions of GNU (more precisely, GNU/Linux distributions) which are entirely free software. More about GNU below.

What is the Free Software Movement?

The free software movement campaigns to win for the users of computing the freedom that comes from free software. Free software puts its users in control of their own computing. Non-free software puts its users under the power of the software's developer. See the video explanation.

Wat is Vrije Software?

Free software means the users have the freedom to run, copy, distribute, study, change and improve the software.

Free software is a matter of liberty, not price. To understand the concept, you should think of “free” as in “free speech”, not as in “free beer”.

More precisely, free software means users of a program have the four essential freedoms:

  • The freedom to run the program as you wish, for any purpose (freedom 0).
  • De vrijheid om een programma te kunnen bestuderen en zonodig aan te passen aan je behoeften (vrijheid 1). Hiervoor moet je de broncode kunnen bekijken.
  • De vrijheid om kopieën weer weg te kunnen geven, zodat je ook je buurman kunt helpen (vrijheid 2).
  • De vrijheid om zelf programma's te kunnen verbeteren en dit weer vrij te geven aan het publiek zodat de hele gemeenschap ervan kan profiteren (vrijheid 3). Ook hiervoor moet je toegang hebben tot de broncode.

Developments in technology and network use have made these freedoms even more important now than they were in 1983.

Nowadays the free software movement goes far beyond developing the GNU system. See the Free Software Foundation's web site for more about what we do, and a list of ways you can help.

More about GNU

GNU is a Unix-like operating system. That means it is a collection of many programs: applications, libraries, developer tools, even games. The development of GNU, started in January 1984, is known as the GNU Project. Many of the programs in GNU are released under the auspices of the GNU Project; those we call GNU packages.

The name “GNU” is a recursive acronym for “GNU's Not Unix.” “GNU” is pronounced g'noo, as one syllable, like saying “grew” but replacing the r with n.

The program in a Unix-like system that allocates machine resources and talk to the hardware is called the “kernel”. GNU is typically used with a kernel called Linux. This combination is the GNU/Linux operating system. GNU/Linux is used by millions, though many call it “Linux” by mistake.

GNU's own kernel, The Hurd, was started in 1990 (before Linux was started). Volunteers continue developing the Hurd because it is an interesting technical project.

logo for gnats GNATS

GNATS is a set of tools for tracking bugs and other user-reported software issues. It is completely open-ended in how its database may be queried, edited and maintained, featuring interfaces ranging from the command-line to Emacs, though the main means of interaction is via its web interface. It is also flexible enough to support user-made utilities. (doc)
