Two weeks back i attended this Open Source conference called FOSS.IN. I wanted to attend at the least three days out of four having very interesting talks but could make it only for one and a half day. The crowd was very techy and this conference is a must attend if you have anything to do with opensource in india.
One of the snaps is of a kernel guy who could not stand at one place, so difficult to catch a snap that i have to take a video ;). His talk was really good.
