Threading

I'm starting to learn about concurrency programming/threading and was wondering about some good resources to start this journey. Concurrency requires a different method of thinking about problems than standard serial code, I'm aware.

So far, I've picked up The Art of Concurrency from O'Reilly and I've been Googling a little (but to not much avail, it seems that threading isn't much of a hobby among programmers and I can see why).

Applications of threading that I would be interested in would be things like timer threading for network timeouts and keeping all the code aware of this happening, design patterns, algorithms, etc. Thank you in advance.

Threads are like pointers: a trivial construct that could only seem confusing if you refuse to understand how the underlying system works.
