Bar Camp is an ad-hoc technical gathering for people to share and learn in an open environment. It is an intense event with discussions, demos and interaction from participants who are the main actors of the event. Think of it as a free-form 2 day conference that is actually led by the participants. The general idea is to transform the traditional conference from a spectator sport to a participant sport. There is no set technology or subject matter, so bring what you do best to the event as a presentation about your passion!
