PyCon US 2015 took place in Montréal, Canada (just like last year). The videos are being uploaded to pyvideo.org. I think we need some more weeks till all the videos get uploaded but at the moment of writing this post there are already 134 videos available.
Here is a nice script of mine (
pyvideo_popularity.py) that orders presentations by popularity.
I just found this Python podcast: http://www.talkpythontome.com/. In the latest episode you can find an interview with “Jesse Davis from MongoDB. Jesse is the maintainer for a number of popular open-source projects including the Python MongoDB driver known as PyMongo and Mongo C (for C/C++ developers, yes you read right! C developers). Jesse discusses how interesting it is to write both Python and C code and how it reawakens part of the brain.” (source)
