This article is a great. Similarly Working Effective with Legacy Code by Michael Feathers (http://amzn.to/1UxwVdL http://amzn.to/1UxwVdL) is a great programming book. I appreciate it because It's really nothing but patterns for dealing with bad code (mostly Java, but most of it translates to other languages). Very little why (which I already know), lots of "how to fix X", aka, great signal to noise ratio.
