Feed your code to coala

Robert Kuska (Kiwi.com) at Brno-Moscow Python Meetup

"So you already use linters for your codebase but it still feels like it's not enough. You want to check for more things, and better, use your own checkers but you want it to be as easy as possible! Meet coala.io, it feeds on your code and makes it better at the same time. With (almost*) no cost"
