This year’s Software Freedom Day is September 20th. If you’re looking for an occasion to help out with the spread of free and open source software, that’s a great one.
An annual event since 2004, SFD is designed to be both a celebration of free software’s successes and a public education effort to help further its acceptance. It has a fairly impressive sponsor and partner list, including Google, Canonical, Sun, the FSF, and more. Participants are encouraged to form local “teams” of free software advocates, to work together on projects.
