Acknowledgments

It took a lot of time to write this book. During that time, many people have helped us out and we thank them for the time they contributed. To all the readers who bought the MEAP edition of the book, thank you for all the feedback that greatly improved this book and for your ongoing patience over the years. We hope you will enjoy the final result and that you learned a lot during the MEAP process.

Special thanks go out to members of the Akka core team, specifically Jonas Bonér, Viktor Klang, Roland Kuhn, Patrik Nordwall, Björn Antonsson, Endre Varga, and Konrad Malawski, who all provided inspiration and invaluable input.

We also want to thank Edwin Roestenburg and CSC Traffic Management in the Netherlands, who trusted us enough to start using Akka for mission-critical projects and provided an incredible opportunity for us to gain our initial experience with Akka. We also want to thank Xebia for the work hours Ray could spend on the book and for providing an incredible workplace for furthering experience with Akka.

We thank Manning Publications for placing their trust in us. This is our first book, so we know this was a high-risk venture for them. We want to thank the following staff at Manning for their excellent work: Mike Stephens, Jeff Bleiel, Ben Berg, Andy Carroll, Kevin Sullivan, Katie Tennant, and Dottie Marsico.
