From today on, SpeedCrunch is no more using SVN at Google Code as its version control system. Instead, it is now hosted at Gitorious, which uses Git. There are dozens of reasons for this move, but I won't mention them here. Googling on why Git is a better choice than SVN returns thousands of results.
EDIT: I've added a page to our wiki with instructions on how to get the latest development code. It is now also the page that you get when you try to access the Source tab in our Google Code site. Note that all the other services (issue tracker, wiki, download hosting, etc) from Google Code are still our official sites, only the code repository has changed to Gitorious.
