To put it mildly, the Yahoo! Bangalore Hack Day completely rocked. There were so many hacks at the end of the day that we had to run demos in two separate rooms simultaneously. I had an amazing time and was incredibly impressed with the energy and creativity of everyone I met. Some of the most talented hackers I have ever met are at Yahoo! Bangalore. (The free buffet Indian lunch was awesome, too.)
Here are some links to first-person accounts from Bangalore hackers:

I’m impressed that the Bangalore team one-upped us back at Yahoo! U.S. — they started their Hack Day promptly at midnight, with thirty-five hackers hunkering down for the long haul. Even more impressive, the core of that late-night group managed to take me out for dinner and beers the night after Hack Day. Their energy after having been up working for days was remarkable in comparison to my mild lethargy from a little jetlag (I arrived the day before Hack Day after 30 hours in transit and 10,000 miles in the air). Consider me impressed with their party skills as well, especially in a city that closes up pretty early.
Before closing this post, I wanted to thank those hackers explicitly. Sumeet, aka the famed “Teemus”, glad you finally got some sleep and it was good seeing you the next day at BarCamp Bangalore. Premshree, thanks for delaying your flight to hang out, and I’m glad you made it to Bombay. Gopal V, thanks for hanging out with us even though you hadn’t slept in days. Pankaj, thanks for keeping me laughing all the night. Hitesh, thanks for coming out after a long day of hacking. Finally, Kapil, glad you enjoyed the chicken. 😉
You guys are truly awesome hackers.
