On the weekend of Dec. 4 and 5, Google, Microsoft, The World Bank and Yahoo! are inviting software developers, independent hackers and students to participate in RHoK #2.
"RHoK brings together volunteer programmers and experts in disaster response for a two-day hackathon to create software solutions that focus on problems related to disaster risk and response. It is an opportunity to meet and work with top software developers and disaster experts, to create and improve open source applications that enable communities to recover from disasters, and to possibly win prizes."
RHOK will be held simultaneously in many locations around the world. The five main stages will be in Chicago, Sao Paolo, Aarhus, Nairobi and Bangalore; and there will be over a dozen satellite events in other global cities.
