This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Thanks for having us this week. We are looking forward to the discussion!
I noticed that you had posted a link to the sample chapter that we've made available. We've posted some additional collateral such as the code and models for the associated case study, a development practice (source, published html and online version) as well as a number of blog postings at the book's website: http://patternsbasedengineering.net.
