This is a talk about Autosustainable Services and a lot of what I've been doing (and getting at) for the past 5 years. It was given at the first PyCon Russia in February 2013. I was a bit out of practice with my public speaking performance, but this is perhaps one of my favorite talks given.
The audio is from the official video of the talk available here (which includes Q+A):
