I attended RubyFringe this year in Toronto and had the chance to interview a few people, one being John Lam of Microsoft, to talk about IronRuby, Microsoft and Open Source and the general direction of the project.
Summary of Talk:
In this interview from RubyFringe, John Lam talks about his work on IronRuby and how Microsoft is approaching Open Source software development.
You can find the interview on the InfoQ web site and is about 1/2 hour in length.
