Status Updates From Java Concurrency in Practice

Chapter 16 - One of these days, I should read the actual Java memory model. But in the meantime, having a nice summary was helpful.

Chapter 15 - The lock-free queue algorithm presented here was fascinating.

Chapter 14 - I already understood condition variables, but it was interesting to see how they work in Java. The AbstractQueuedSynchronizer was new to me. I don't think I could use it solely based on the info in this book, though.

Chapter 13 - I didn't really understand explicit Lock objects in Java before. Good to know, I guess. Although honestly I really love Java's synchronized keyword.

Chapter 12 - Lots of great advice here!

A lot of this was stuff I knew or common sense. Still, I have a feeling I'll be coming back to this chapter if I'm ever seriously trying to improve the performance of a concurrent program.
