This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
There is an old book that was very popular in Russia: Etudes for Programmers by Charles Wetherell I wonder how well known it is here... There is only one review on Amazon. Have anybody read it? Another one is probably classic: How to Solve It by G. Polya. -- it is about mathematical problems, but generalizations are so broad that they can be applied to just about any pronlem. What other books can you recommend?
