As can be seen from the FOSS.in/2009 "Omelette Post", in addition to the regular FOSS.in schedule until 5pm every day, there will be additional hacker talks until 10.30pm, which might not necessarily be directly connected with FOSS.
Since I'm personally a member of both the hacker community (in the very specific sense of working and uncovering weaknesses in communication systems) as well as a 100% Free and Open Source person, I obviously like this kind of combination. To me, both go hand in hand - even though I know not everyone will have the same opinion.
In the end, learning about and playing freely with technology is what both communities want to do.
I'm looking forward to see the FOSS.in CfP...
