19 June: FreeBSD celebrated its 20th birthday today. On June 19, 1993, Jordan Hubbard, Rod Grimes, and David Greenman announced to the world the creation of their new fork of the BSD 4.3 operating system.
FreeBSD was derived from the 386BSD 0.1 release from Bill and Lynne Jolitz with its 1.0 release in Nov 1993. Its stated goals were to create a fast, stable, reliable server OS for i386 systems.
Since then, it has become the backbone of countless products and has grown to supporting 64bit computing, embedded devices, and desktop users.
