Shriram Krishnamurthi, Arjun Guha, Leo Meyerovich, and I wrote a post about Flapjax on PL Perspectives, the SIGPLAN blog. (Thanks to Mike Hicks for helping us edit the post!)
Flapjax won the OOPSLA MIP award for 2009 (though the SIGPLAN website isn’t yet up to date). Our blog post is about the slightly unconventional way we worked: most of the Flapjax work happened in 2006 and 2007, but we didn’t even try to write the paper until several years later (Leo and I were in grad school). Rather than recapitulate those ideas, go read the post!
