I gave this talk at DockerCon Europe 2018 in Barcelona. It's about how to do efficient code reviews by using a very rare skill: Diplomacy. I encourage all developers to watch this talk, the feedback I received from it was extremely positive. It really changed the way some developers do their code reviews. I made this talk because this is the method I found that really worked for me in the first place, so it really works, it's not just words and theory.
