I started CheckR with a friend. It hopes to be a static source analysis tool for Ruby code, along the lines of lint for C/C++. We are actively developing on it in a remote, ping pong, test driven development way. We are very close to our first alpha release. The first release will hopefully add some small value and be able to catch a few errors earlier in the development cycle. I guess we need autocheckr too. And we definitely need to run checkr against itself.
