The slides for this talk are on SlideShare and, given that there is a lot of code on them, they might be a handy reference. Check ‘em out.
In preparation for this talk I put together an exercise foolishly thinking I might have time during the talk to actually do some coding to provide some more concrete examples. I ran out of time but the exercise is still out there if you want to practice some of these techniques.
I also plan to record a series of screencasts where I show off some of these techniques against this repository. Watch for those here or on my YouTube channel.
