Writing programs is fun, but making them fast can be a pain. Python programs are no exception to that, but the basic profiling toolchain is actually not that complicated to use. Here, I would like to show you how you can quickly profile and analyze your Python code to find what part of the code you should optimize.Read More
Last week I was in Tokyo, Japan for the OpenStack Summit, discussing the new Mitaka version that will be released in 6 months.

I've spent some time translating it into English so you can read it if you don't understand French! I hope you'll enjoy it.Read More
