This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
Here's one example of the topics I like to blog about http://codingjunkie.net/guava-eventbus (Event Programming with the Guava EventBus)
I also cover other topics, right now I'm focusing on Hadoop/MapReduce.
