Have you ever wanted to contribute back to Rails? Hashrocket Chicago will be hosting a 2-day hackfest to help test the upcoming 3.1 release. The purpose is to help iron out any outstanding bugs or issues before they officially release. You can upgrade an existing Rails project, make a new one or check open bugs and reproduce some of the issues.
