This summer, on June 1-2, 2013, residents in cities across the Nation will join together to improve their communities and governments as part of the National Day of Civic Hacking. A number of Federal agencies, including NASA, the Census Bureau, and the Department of Labor, are participating by offering specific challenges for hackers to work during the event. The event is taking place in conjunction with Random Hacks of Kindness and Code for America's Brigade meetings and is being modeled after the Innovation Endeavors’ Super Happy Block Party.
