Effectful Effects - Unifying Bidirectional Communication between Software Components
Yizhou Zhang, assistant professor at the University of Waterloo, presented bidirectional algebraic effects, a new programming abstraction that subsumes current control flow patterns (e.g., exceptions, promises, generators) while supporting bidirectional control flows. With the new typed abstraction, all declared effects are handled, and no effects are accidentally handled by the wrong handler.

How Dropbox Created a Distributed Async Task Framework at Scale
Engineers at Dropbox designed a distributed async task framework (ATF) that can handle tens of thousands of async tasks scheduled per second. ATF's main feature is its ability to enable developers to define callbacks and schedule tasks that execute against these pre-defined callbacks.

Swift Aims to Become a Data Race-Free Concurrent Language
The Swift team has published its roadmap to improve concurrency support in Swift. In a first phase, Swift will gain the async syntax and actors, while in a second phase focus will be on eliminating data races and deadlocks.

Rust Gets Zero-Cost Async/Await Support in Rust 1.39
After getting support for futures in version 1.36, Rust has finally stabilized async/.await in version 1.39. As Rust core team member Niko Matsakis explains, contrary to other languages, async/.await is a zero-cost abstraction in Rust.

Slick 3: Reactive Streams for Asynchronous Database Access in Scala
Slick, Typesafe's database query and access library for Scala, now supports the Reactive Streams API in the just released version 3.0. This enables developers to query their databases asynchronously and non-blocking. InfoQ talked to Slich Tech-Lead Stefan Zeiger to learn more about the new features and what they've planned for the future.

Python 3.5 will Support Async/Await Asynchronous Programming
Python 3.5 will add support for coroutines with async and await syntax, according to Python Enhancement Proposal (PEP) #0492. The proposal aims at making coroutines a native Python language feature and to "establish a common, easily approachable, mental model of asynchronous programming."

The Strengths and Weaknesses of Microservices
There has been significant buzz around microservices lately, enough to generate some hype. After implementing heavy and cumbersome SOA solutions for more than a decade, are microservices the solution the industry has been waiting for? Or, are microservices simpler than monolithic solutions?

Scalability in a Reactive World
We have to maximize locality of reference and minimize contention to make systems scale, Jonas Bonér, creator of the Akka project, stated in a recent presentation about scalability in reactive systems. By using a share nothing architecture, build on an event-driven foundation and adhering to core principles that have been proven to work for ages we can write really scalable systems.

The Performance of Dart 1.3 Is on Par with Node.js
The Google Dart team has announced Dart SDK 1.3 which improves the performance of asynchronous server-side code to the point that Dart VM is on par with Node.js, the later using another Google technology, the V8 engine.

Akka Actors vs. Java EJBs from a High-Level Concurrency Perspective
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.
