Sure, the freshly announced National Day of Civic Hacking may sound like it'll occupy a single square on your calendar, but the White House wants folks to get together on June 1st and 2nd to solve problems with a bit of coding and info from Uncle Sam. Government agencies including the Census Bureau, NASA and the Department of Labor are set to serve up publicly available data for developers and entrepreneurs to concoct solutions for problems affecting cities, states and the country. In addition to government support, the effort is being organized by outfits including Code for America, Random Hacks of Kindness and Eric Schmidt's Innovation Endeavors. Currently, 27 cities have events scheduled during the weekend in question, but the initiative's coordinators are looking to spawn even more powwows throughout the US.
