GNU - Richard Stallman

"Free Unix!

Starting this Thanksgiving I am going to write a complete
Unix-compatible software system called GNU (for Gnu's Not Unix), and
give it away free to everyone who can use it.  Contributions of time,
money, programs and equipment are greatly needed."

Jeder soll das Recht haben Software auszuführen, zu studieren und abzuändern, sowie sie mit und ohne Änderungen weiter zu verbreiten 

Niemand soll durch proprietary software eingeschränkt werden

Eines der ersten großen erfolgreichen Open Source OS

1991

Hello everybody out there using minix -
  I'm doing a (free) operating system (just a hobby, won't be big and
  professional like gnu) for 386(486) AT clones.  This has been brewing
  since april, and is starting to get ready.  I'd like any feedback on
  things people like/dislike in minix, as my OS resembles it somewhat
  (same physical layout of the file-system (due to practical reasons)
  among other things).

  I've currently ported bash(1.08) and gcc(1.40), and things seem to work.
  This implies that I'll get something practical within a few months, and
  I'd like to know what features most people would want.  Any suggestions
  are welcome, but I won't promise I'll implement them :-)
