Reading this book will help you "get" Akka, to understand how best to approach programming with actors and futures. One unique feature of this book is that it is written in a refreshingly entertaining style for a tech book. As a sample, check out this snippet from the introduction to the chapter on futures:
We’ve come to the second great axis of Akka’s concurrency paradigm, the future. Futures have been around for a while now, but you’ve probably never seen them like this. These are futures on steroids; tiger steroids, laced with the blood of Superman, dripping with the testosterone of Batman, and in- fused with the power of Green Lantern’s Ring. If you’re not ready to have your brain set on fire, close this book, curl up in the fetal position, and sing Twinkle, Twinkle Little Star softly to yourself until you’re good to go.
The future and the actor share a certain number of similarities as well as differences, but they are also designed to work together very well. In this chapter, we’ll see these similarities and differences as well as explore some patterns for tying the two components together.
