This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I took a look at Go Tour.
Are there any exercises, perhaps with walk through solutions, that are a step above 'Hello World'?
Maybe a simple word game, math puzzle ala Project Euler, all written in idiomatic Go.
