Have you looked into Scala? Scala is a new object-functional JVM language. It is statically typed and type inferred. It is multi-paradigm and supports both object oriented and functional programming. And it happens to be my favorite programming language.

If you are interested in Scala, how you are planning to learn Scala? You probably are going to pick up a book or two and follow through some examples. And hopefully some point down the line you will learn the language, its syntax and if you get excited enough maybe build large applications using it. But what if I tell you that there is a better path to enlightenment in order to learn Scala?

Scala Koans, a set of test cases that will teach you Scala language. The Scala koans will help the audience learn the language, syntax and the structure of the language through test cases. It will also teach the functional programming and object oriented features of the language. Since learning is guided by failing tests it allows developers to think and play with the language while they are learning.

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 both in Scala and 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.

Akka is the only framework that I think is able to provide the right set of tools that we need to build correctly a scalable and concurrent application. And knowing Akka will help audience to select the right abstraction when they build their next concurrent application.

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.

Here is the outline of the presentation

• What is Camel?
• Talk about enterprise integration patterns
• Camel under the hood
• Code example integrating 2-3 applications using Camel
• Synchronous vs Asynchronous application
• Designing application based on message passing using Camel
