Call For Code, returning for its third year, is a five year developers’ challenge issued by David Clark Cause, IBM, the Linux Foundation, and United Nations Human Rights. Each year the coalition issues a global challenge calling for solutions to some of the world’s largest problems. Per an IBM press release: Last year’s grand-prize winner, Promoteo, received $200,000 and mentoring and development support from IBM for developing a device for emergency personnel to use during disaster-response that monitors air quality. Mami Mizutori, Special Representative of the United Nations Secretary-General (SRSG) for Disaster Risk Reduction, said: We’ve covered the Call for Code challenge for the past two years, including our review of a recent documentary featuring the real life heroes who’ve participated in the past events.
