This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
I've read only a little about it, in particular in the Java Community Process section of sun's site. I'm interested, generally, in OLAP. It seems to be a very important and valuable technology. ------------------
