Perl Mongers in Chicago are hosting a hackathon on the weekend of December 14-16 (all day Fri-Sun). It's open-ended, so bring whatever project you want to work on and get some other people to help you out! It's a great way to spend some quality time with both your favorite Perl projects and your fellow Perl Mongers :)
The event is of course free, and it will be on the second floor of the J.Ira & Nicki Harris Family Hostel. Food will be provided :) Finally, if you're coming in from out of town, we've reserved rooms at the hostel for $115 (Thursday-Sunday). Pay for your room through The Perl Review.
Contact Jonathan Rockway (jon at jrock dot us) or Josh McAdams (joshua dot mcadams at gmail dot com) for any questions.
