What's less common is for major national governments to do the same thing.
Sure enough, though, the White House Office of Science Technology and Policy on Tuesday announced the National Day of Civic Hacking on June 1 and 2, calling it "an opportunity for software developers, technologists, and entrepreneurs to unleash their can-do American spirit by collaboratively harnessing publicly-released data and code to create innovative solutions for problems that affect Americans."
Civic hacking communities have existed for some time already, of course, but this summer's event will be the first time local developers from across the nation unite for this shared purpose, the White House said.
A coalition of organizations, companies, and government agencies have banded together in support of it and will host activities across the country that invite anyone to become part of the civic hacker community, regardless of their skills.
Federal agencies including NASA, the Census Bureau, and the Department of Labor are offering specific challenges for hackers during the event.
'An ecosystem for change'
"This is an opportunity for citizens in every town and city across the nation to roll up their sleeves, get involved, and work together to improve our society by cultivating an ecosystem for innovation and change," the White House announcement explains.
Activities are now being planned in cities including Austin, Texas; Bend, Ore.; Boston; Chicago; Denver; Detroit; Palo Alto, Calif.; Portland, Maine; New York City; Philadelphia; San Diego; San Francisco; and Seattle.
Participants can help by planning an event, supporting an event, or contributing data, code, or other resources.
