There are both commonalities and some differences when comparing architectural principles and coding styles in Akka Actors and Java EE 7 Enterprise JavaBeans, specifically stateless session beans and JMS message-driven beans, Dr Gerald Loeffler concludes in a recent introductory talk when explaining and comparing the three approaches from a high-level concurrency view.
Parse, acquired by Facebook a few months ago, has recently open-sourced a collection of low-level libraries for Android and iOS collectively called Bolts.

While it has been less than a month since the announcement of the core.async Clojure/ClojureScript library, a number of blog posts have been published describing how to use it effectively to avoid "callback hell" in front-end code, and showing off simple code resulting in some impressive demos.
The recently released Windows Azure Service Bus Client SDK provides support for task based versions of all asynchronous APIs in addition to performance improvements.
Sometimes the best way to understand pitfalls in one language is to see how another language prevents them. Tomas Petricek, author of Real-World Functional Programming, discusses seven common mistakes found in asynchronous C# code and demonstrates how F# makes them less likely to occur.
Atmosphere 1.0 is a new Java/Scala/Groovy framework that attempts to abstract asynchronous communication between the web browser and the application server. It transparently supports Web Sockets, HTML5 Server Side events and other application server specific solutions when available, with long polling as a fallback.
