In Java, Math.abs can return a negative number (!). I heard about it from here.
Python 2.6 is in beta. In Python, last fall Guido talked about the GIL. Now I am interested to see a "multiprocessing" module which "supports the spawning of processes using a similar API of the threading module". This is pretty cool - it will allow programs to take advantage of multiple processors, while maintaining the GIL.
A Python 3k hack from here. At least on the Python 3k I'm using , __signature__ isn't available yet, so this doesn't work yet. Annotations can be useful though.

I am currently working for Avid in Tewksbury, MA, as a "Media Engine Infrastructure Software Engineer Intern". It's going well so far as I dig deeper and deeper into c++.
