I contribute to Sahana, the FOSS Disaster Management System. It’s great to be working for such a worthy cause, knowing that it would be used to help manage every major disaster around the world . What’s more, its all FOSS :), and has been deployed succesfully in major locations around
the world in the past.
Sahana has seen its way through 3 phases since January 2005, and is currently labeled Sahana-Phase3. I have been a contributor since phase1, and am part of the core-team for phase2 and phase3. I do find time 2 days a hectic week to attend the Sahana lab based in the University of Colombo, Sri Lanka. The rest of the week is spent on my full time priority, i.e attending lectures at the University of Moratuwa 😉
