Even after graduating from NC State, I've been volunteering regularly with a few others working on Dr. Geheringer's Expertiza project. It's a peer-review web app written in Ruby on Rails that is used at a handfull of universities. We open-sourced it on Github ( http://github.com/expertiza/expertiza ) to encourage open participation, both with reporting issues and getting developers to contribute. Switching to git has been great for integrating the contributions we get. We have a variety of people contributing to the project now, including volunteers who have since graduated, Dr. Gehringer and a few core developers, and contributors from his object oriented design class. In the past several months, we've made a lot of progress modernizing the project - getting it on a newer version of the Rails framework, automating deploys, automating acceptance testing (cucumber), and getting off subversion. We're focusing now on expanding our test coverage and refactoring a lot of old Rails 1.x code. We'd love to have others volunteer with the project. Let me know if you have any other questions you'd like me to expand on.
