What if people living in conflict zones could predict where violence was going to break out? A small group of Kenyans created an early-warning tool that aims to do just this. The project is called Ushahidi, which means "testimony" in Swahili. Started in the aftermath of the violence that followed the Kenyan elections, the developers are about to launch a new version of the software that will help communities around the world map and predict violence. Guest: David Kobia, co-founder of Ushahidi.
