The second edition of BarCamp Chennai will happen this weekend (Oct-17 and 18) at IIT Madras.
The first edition which happened in April 2006 and was a great success and I hope it will the same this year too. It has already started to get some press coverage and you can find the article from Decaan Chronicle here, kudos to the organizing team.
I will be attending the sessions scheduled for the second day and let me know if you are coming and we can meet up.
More details about the BarCamp can you found at the official BarCamp Chennai Website.
