It’s the last day to apply to Y Combinator’s first hackathon, YC Hacks. The hackathon will be hosted at YC’s office in Mountain View, CA on August 2-3. 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.Kickoff will be at noon on Saturday, August 2. YC companies that develop platforms, services and developer tools, will be around to act as mentors. Judging will happen the evening of August 3. YC alumni are donating prizes, and the top teams will get guaranteed YC interviews for the next batch.
