Thirty years ago today Richard Stallman announced his plans to build GNU in a post to the net.unix-wizards mailing list. What followed was the birth of the free software movement, the founding of the Free Software Foundation and the GNU public license (GPL) -- now used by the Linux operating system. His words continue to inspire software developers to this day:
"I consider that the golden rule requires that if I like a program I must share it with other people who like it. I cannot in good conscience sign a nondisclosure agreement or a software license agreement," Stallman wrote in his original email from Sept. 27, 1983 (see the full text at LWN.net ).
To celebrate this important milestone for the GNU project and free software, we asked the Linux community on Twitter to tell us what GNU means to them. Here are some of their answers.

@linuxfoundation  GNU is the reason why I share my code openly so others can improve it!— James Loyd (@jamestloyd) September 25, 2013
