O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.I’ve been on the O’Reilly platform for more than eight years.

It's worth its weight in gold, in terms of what it allows me to do.
Alternative Future frameworks
Scala futures and promises API resulted from an attempt to consolidate several different APIs for asynchronous programming, among them, legacy Scala futures, Akka futures, Scalaz futures, and Twitter's Finagle futures. Legacy Scala futures and Akka futures have already converged to the futures and promises API that you've learned about so far in this chapter. Finagle's com.twitter.util.Future type is planned to eventually implement the same interface as scala.concurrent.Future, while the Scalaz scalaz.concurrent.Future type implements a slightly different interface. In this section, we give a brief of Scalaz futures.
To use Scalaz, we add the following dependency to the build.sbt file:
libraryDependencies += "org.scalaz" ...
