Badass Tool - Find bad code by parsing Airbrake error log

"This is a simple script that parses exception logs from Airbrake, figures out the most likely offending line in the app that caused the exception based on the Airbrake backtrace, and then uses a local copy of the app (and Git blame) to figure out who wrote that line.

It then ranks developers using a scoring algorithm that biases towards high exception rates for individual exceptions, and also a high number of different types of exceptions.

In short: it's probably best not to be at the top of this leaderboard!"
