The Yahoo Developer Network is organizing a HackDay in Sunnyvalle (California) September 29th/30th. The idea is to invite people to workshows explaining and demonstrating the APIs available on YDN for a full day, then to invite them to code and program hacks the whole night until noon tomorrow. All the hacks will be demonstrated tomorrow afternoon and there will be prizes for the best ones.

This kind of event is really appealing to my geek side. Discovering and mastering technologies, programming cool stuff in the middle of the night while discussing with people about programmation. The sure way to have a happy day.
