Finally the books I ordered in the beginning of December have arrived 
- Advanced Programing in the Unix Environment
- Unix Network Programing Volumes 1 and 2
I think that these books are the bibles of network programing and they should be a must read for any C developer.
I have also ordered these two:
- Myths of Security
- The Art of Lean Software Development
I’m pretty excited about the Unix Network programing volume 1 since it is third edition and I have read only the second. In the third they cover the SCTP which is a very nice protocol. I actually implemented SCTP in OpenVPN and the book will help me understand just how many mistakes I have made in my implementation
