Forty years of GNU

The Free Software Foundation looks
forward to the 40th anniversary of the GNU project, coming soon:

On September 27, 1983, a computer scientist named Richard Stallman
announced the plan to develop a free software Unix-like operating
system called GNU, for 'GNU's not Unix.' GNU is the only operating
system developed specifically for the sake of users' freedom, and
has remained true to its founding ideals for forty years.
