Awesome read, covering various broad strategies to solving "hard" problems. Discusses deterministic, approximation, randomized, and heuristic approaches, at the same time providing realistic enough examples that the tradeoffs between each is made evident.

I'm still peeing myself. For punctuation nerds who are absolutely disgusted with the current state of English literary skills. This is a masterfully written, much appreciated break from my typical geekish read.

I love historical accounts that spend entire chapters discussing PDP-10s and 11s. This book is all that and more, detailing the life one of the most eccentric and intelligent figures in the world of software. I've also read the following similar accounts, all of which I would highly recommend: The Cathedral and the Bazaar, Rebel Code, Just for Fun, The Art of UNIX Programming. Note: This book is available online for free... right here.

Game Physics
by David H. Eberly

This book is unfortunately primarily a refresher course in high school physics, perhaps university level, but there are a couple sections which make this one a keeper. I'd recommend it for reference, not something with which you'd want to curl up in front of the fireplace.

Written by a couple of my fellow Microsofties, this book details the threat modeling process in great detail. It's definitely a process book, and as such makes a few assumptions I would prefer to steer away from (e.g. lack of quantitative data showing why the investment in threat modeling is a Good Thing(tm)). That said, there is a lot of good material here.
