Code Camps are community driven events where developers come and learn from their peers. Since it's peer driven, topics cover all platforms, programming languages, and disciplines, and the people delivering the sessions are local peers and local experts.
The Southern California code camp is slightly different than other code camps in that they invite independent bands to play at the Geek Dinner after the first day's sessions.
This is a free event over a Saturday and Sunday and they are done twice a year. Once in the Winter and once in the Summer.
This summer's Code Camp is going to be June 30th and July 1st on the UCSD Campus.
