Last month, we went to CityCamp to see what brave new technologies the City and County of Honolulu is cooking up.

Now, the city will hold its first “Hackathon” to develop computer apps designed to improve the day-to-day lives of Honolulu residents.

The city will bring its “ever-broadening array of government data” to the party, according to a press release, and is inviting entrepreneurs, developers and programmers to bring their skills.

The free event is scheduled for Friday and Saturday, Jan. 20-21, at McCoy Pavilion in Ala Moana Beach Park.
