Jeff Brewster and I had a great time at the Google Summer of Code (GSoC) 2009 Mentor Summit. We were royally welcomed, well-fed, and given a great springboard for mind-melding with the other GSoC mentors.
The summit was decidedly unconference style: meeting ideas were shared beforehand but the sessions themselves scheduled and run on-the-fly. I wanted to learn more about project hosting since we recently worked the Mifos project through some issues with hosting at java.net (and ended up moving to SourceForge), so I co-hosted a session called Project Hosting Horrors. The session filled up a room and we got useful feedback from lots of projects about what works with hosting, what doesn’t, and ideas on different approaches.
