As most of you know I have the last edition of the HDB book. Well this time chapter 23 is not on the topic we are to read, in fact that topic is not evident in the book. This is a bit frustrating. Until now this book has been very effective, and useful. The changes haven't been blocking my understanding of the concepts, some examples have been different, but it's compatible.

Anyway, since I was behind in my blogging I wanted to catch up. I'll blog on content after class tonight.
