Drat, now I have another audience to consider when writing blog entries.
I've been using python since about version 1.5, I currently code some bioinformatics software using a mix of C++ and Python. I was a long time debian/free software geek until pushed over os x by trying to get alsa to send music out a TOSlink port. Though like many other linux switchers, I keep trying to drag a bunch of open source software onto OS X, eventually I hope to reduce my use of OS X down to a nice set of device drivers.
This year was my first PyCon, which felt worth while even after facing the annoyance of the TSA. (Though I also attended last years SciPy.)
