New books for my geekshelf

Just ordered three new books!
They all have really great rating, and I actually read some on Google Books (I really love that beast..I never waste my money on books)

I don’t know if I will ever be done reading all these books, but I think they deserve to be on my geekshelf, which is already full of computer science and programming books…and the Harry Potter series

1. Algorithm Design Manual

How many of these algorithm books do I need before I clearly understand NP-complete problems?

2. Concurrency in Java

Something I really need. UC San Diego emphasized a lot in Java (and C). However, I took my operating system class with a professor who favored C. So.. I never had to deal with multithreading with Java craps. This books seems to cover a lot of details on how to do multithreading correctly in Java, plus the concept of multithreading.

3. Coders at Work

Interviews of many famous coders… this should be fun.
