Python 3.3 is out and it's a great logo for 311, not for in general, but just for the release. Mike drop it one of the early developers and it is actually managing our team in Microsoft. I had some interaction with the also bytecode version king because I was looking at things to do in the testing and in the interpreter that are kind of like that. So this is a library can kind of from Python write bytecode and it's pretty neat. Pablo not all by package. I'm going to say memory use memory. The one and only Python memory profiler. It's awesome.
