I was graciously invited to give the keynote presentation at this year's PyCon Singapore. Luckily, I love to hack on long plane rides. See the slides from the talk below.
I showed some analytics on Python posts on Stackoverflow during the talk, here is the IPython notebook. The raw data is right here.
I also gave a half day pandas tutorial, here is the IPython notebook. You will need the data to do it yourself, here's a download link.
