Have you ever thought your code was too complicated? How about that other person's code? Yesterday's "Development by the Numbers" DrupalCon session was a fantastic session discussing metrics for measuring complication, long term consequences to maintaining convoluted code, and how to manage your code base.
A big thanks to Anthony Ferrara (@ircmaxell) for taking one of those core concepts we all kind of know and demonstrating it in a way that makes sense and that we can relay to our peers. I highly recommended watching this session to developers of all levels.
