Our goal is to give smart hackers an excuse to get together and spend time building something they find interesting. We don't have a theme -- we want to leave it open to any good ideas.

Registration will open at 10am on Saturday, August 2, and the hackathon will officially kick off at noon. Judging will happen on the evening of the 3rd. 

PLEASE NOTE: YC Hacks is only open to people who have registered through YC's system. We have a limited amount of space and can only accommodate the people who have been accepted + notified.
