https://youtu.be/6RQb7Hz_TPw Setting up Akka clustering is quite easy and provides a way to distribute work across multiple machines in the cluster. In many cases this requires no changes to an Actor compared to a non-cluster deployment. In this screencast, I walk through setting up a cluster and compare deploying an actor in a local actor … Read More
This talk will be an accessible exploration of the JVM Heap, thread stacks and concurrency primitives on the JVM and how to compose multi-threaded code in Java and Scala.
This talk will show off Scala.js and how you can get started using it. Starting from nothing, we will build a number of small Scala.js applications, which will hopefully demonstrate this promise. No Scala experience required.

From the abstract: Spark is an open-source computation platform for Big Data. Leaders in the Hadoop community, such as Cloudera, have embraced Spark as a replacement for MapReduce, the venerable standard for writing Hadoop jobs. This talk explores why this change is needed. Spark provides two important benefits compared to MapReduce. First, its performance is … Read More

From the abstract: Jan will show how the principles of reactive design apply to APIs. In particular, Jan will show how to serve & consume REST APIs using Scala and Spray. The talk will explain the components in Spray, how they build on each other to offer convenient abstractions, and how you can easily combine … Read More

From the abstract: “By now, it’s no secret that asynchronous and non-blocking code means fast and responsive software stacks that scale to the moon. The only problem? Asynchronous code usually means callback hell that’s impossible to write, impossible to reason about, and even worse to maintain. Not any more— Scala 2.10 brings an asynchronous, completely … Read More

From the abstract: “Erlang has made popular the notation of asynchronous message passing as means of distribution and Scaling. While the idea of “actors” is fundamentally simple, how do we, the software engineers, make use of this abstraction to develop real life, scalable systems? This talk designs a scalable distributed search service using Akka and … Read More

From the abstract: “Ever wished the compiler could make asynchronous programming easier? Enter Scala Async. Do asynchronous I/O like “normal” blocking I/O, program with Futures and Promises even more naturally! Scala Async makes it possible to “suspend” at arbitrary points in a block of regular Scala code, and to “resume” from that point later— all … Read More

From the abstract: “Both Clojure and Scala target enterprise-sized challenges, but the development styles are very different. We will live-code a small webapp in both languages, on two projectors, while demonstrating how each language influences our thought process, and the toolchain and library best practices. We will discuss how Scala makes you think in types, … Read More
