David Wong hasn't been at NCC Cryptography for a long time, so I assume we'll be waiting a long time before we get to Linear and Differential cryptanalysis, but if that's a thing you're interested in, what you want is the Heys tutorial:
Interestingly enough, the Square attack (otherwise more generally known as integral cryptanalysis) is much more powerful than regular linear or differential cryptanalysis when applied to the AES.

My recommendation: print it out to a PDF with huge margins so you can make notes, and then work through all the worked examples.
