It's a Twister - Now with More XML
Holy community code, Batman. Facebook has been launching open source projects like crazy in the past few months. (This would be a Good Thing -- I think they launched two today just while I refreshed the page!) Things like Cassandra, Thrift, and Hive are great additions to the community, and hopefully the rewards will go both ways. One of the projects I've been playing with is Tornado, FriendFeed's Python web framework. It's quite simple to dive into if you are familiar with any of the dozens of web frameworks available for Python (like web.py, Pylons, CherryPy, etc.), and it's very fast. (But, in the immortal words of LeVar Burton, "don't take my word for it.")
