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.
I don't think I could say it any better than Matt Taylor did. But I will add that Grails is a great framework for new web developers. It's a breeze to get going and to build useful apps, but then you can keep digging deeper the more you learn. It's like a bicycle with training wheels that automatically fall off when you don't need them anymore!
