Ubuntu is a South African ideology focusing on relationships within communities. "I am because we are." "A person 'becomes human' through other persons." "Humanity towards others." Catholic Archbishop Desmond Tutu gave a further definition:
A person with ubuntu is open and available to others, affirming of others, does not feel threatened that others are able and good, for he or she has a proper self-assurance that comes from knowing that he or she belongs in a greater whole and is diminished when others are humiliated or diminished, when others are tortured or oppressed.
Looking further, I enjoyed this video by Nelson Mandela, former President of South Africa-
I am glad Mark Shuttleworth picked this inspired word for the greatest GNU/Linux distribution. It embraces the spirit of Free and Open Source Software. It promotes community among users. Trully, it is "Linux for Human Beings". There just isn't another distro out there that quite compares to the spirit of the Ubuntu GNU/Linux project.
