I'm in need of a large repository of open source projects (around 1000 or more, the programming languages don't matter, but a good mix will be nice) for my research work. I thought of downloading projects from Github/SourceForge/Codeplex, but I cannot find the right API's to do it.
Does anyone know whether it is possible to download projects from the aforementioned websites (Like, how Twitter allows us to grab tweets from the public time-line)? Or any other place where I can get a good mix of open source projects?
