The event `CodeConf` was a two-day gathering of developers where speakers shared their expertise on various topics such as space exploration, documentation for open source communities, and the importance of diversity in teams, with Wil Shipely's closing speech being particularly notable. The attendees also got to socialize at dinners, including one hosted by Engine Yard, which featured a whisky tour. `Tech@NYU` held its Spring 2011 edition of the HackNY college hackathon, where students from various universities competed to build projects using APIs and coding skills, with winners receiving prizes for their efforts, including Etsy Shopping Network and WebGL Filters apps. The event also showcased the potential for students to gain experience through internships with NYC startups after the competition.
