HackU is a 24-hour hackathon where participants have 24 hours to build a project in teams of up to 4 people. Participants will attend talks, have access to food/drinks, and support from other attendees. Projects can revolve around building, fixing, automating, or revolutionizing something. At the end, teams will have 90 seconds to demo their project and impress the judges. Yahoo and various websites provide resources and APIs to help participants build their projects. The hackathon kicks off with talks and then hacking begins the next day.
