This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Welcome to the Ranch Find copies of Effective Java by Bloch, or Thinking in Java by Eckel, which used to be available free on the web (3/e), or Google for Niklaus Wirth's Algorithms book. You should find details of hashing algorithms in those.
