An acconym used by Discowrld fans to commemorate people who have passed on. The origin is the novel Going Postal by Sir Terry Pratchett, in which semaphore operators send the names of their fallen comrades back and forth along the semaphore system, known as the clacks, with this code attached.

The code translates as follows:
G: General broadcast, send in all directions
N: Do not log the mmessage
U: Sent the message back when it reaches the end of the line

By sending the code and the name the operators are asking to keep the persons name cycling the system for ever. Similar to the notion that a person is never gone while others still speak their name.

The GNU Project was launched in 1984 to develop a complete Unix-like operating system which is free software: the GNU system. (GNU is a recursive acronym for "GNU's Not Unix")

Variants of the GNU operating system, which use the kernel Linux, are now widely used; though these systems are often referred to as "Linux", they are more accurately called GNU/Linux systems.

A group of people, lead by Richard Stallman, who think that all programs should be given to them for free. They created a license, GPL, that isn't compatible with itself, and insist on calling Linux GNU\Linux. Instead of calling open source programs 'Open Source' they call them 'Free', regardless of weither or not it is free.
GNU wrote the GPL, but I think that the BSD license is much better.
