Presentations

Simple concurrency with Akka

In this presentation I will introduce an open source tool called Akka. This tool is written in Scala and provides the right abstract level we need to write fault tolerant and scalable application in Java. Akka framework comes with three different approaches that we could use to build concurrent applications: Actors, STM (Software Transaction Memory) and Agent. I will discuss each of these approaches with code examples so that audience could see how these approaches works and some of its use cases.

Having fun building web application with Play

The Play 2.0 web framework bundles all these features in a nice developer friendly framework where you can actually have fun building web applications again.

Solving integration problems with Apache Camel

Enterprise integration is a hard problem. Not only you have deal with multiple applications build using various programming languages and deployed in various platforms, they also speak different protocols. In this presentation we will introduce you to an open source tool integration framework called Apache Camel. This tool implements all the well know integration patterns from “Enterprise Integration Patterns” book by Gregor Hohpe and Bobby Woolf and provides you with a nice DSL to integration heterogeneous systems.
