I got my copy of Practical Cryptography yesterday, and so far my expectations have been met. It's what you'd expect if several of the world's foremeost cryptographers walked down out of their ivory math towers and started talking about the dirty details of how to make a crypto system really work. They don't pull any punches, and they call a spade a spade (which even too few security people are willing to do).
Neat stuff. I'm sure I'll write more about it.
