Underneath the beautiful veneer of our Ruby libraries lies a twisted tangle of writhing guts. Maybe you're curious how the pieces fit together or maybe you're tracking down a bug, either way it's easy to get lost in the blood and bile that ties our code together. In this talk you'll learn how to use simple and sharp Ruby tools to slice into large libraries with surgical precision. We'll do some live hacking on Rails on the stage and cover useful code probing techniques. Turn your impossible bugs into pull requests, and level up your programming skills by Dissecting Ruby with Ruby.
