This summer, I began working on a tutorial for the 128-bit AES cryptosystem. I ended up putting it down for quite a few months and am now just getting back to it. I hope to have it done in the next three weeks, pending school work and such. If it doesn't get done by the end of Thanksgiving break, it will get finished over winter break.

After that tutorial, I'm going to put something together on P and NP-Completeness proofs. Possibly something on Matroid Theory and greedy basis algorithms to follow.
