Presentations

I have seen the top Akka mountain, and it is good.

Presentation on Akka. A set various tools to write concurrent, fault-tolerant applications using immutable data, asyncronous message passing using local and remote actors, software transactional memory, and supervised systems.

Akka is a middleware, but it is not your 1990s middleware. Akka is a set of various tools to write concurrent, fault-tolerant applications using immutable data, asyncronous message passing using local and remote actors, software transactional memory, and supervised systems. Akka is also part of the Typesafe stack, a stack that include the Play web framework and the Scala programming language. This Akka presentation will cover both Scala and Java style usage of Akka and give the audience a 30k view of how it comes together. While this presentation is not interactive, all demos will be available on github for those that want to "play" along with their laptops.

Playing with the Play Framework

The presentation will cover an introduction on the framework by creating a basic web application in both Java and Scala to get you started.

The Play Framework is a lightweight and stateless web framework that is part of the TypeSafe stack, a stack which includes Akka middleware and the Scala programming language. The presentation will cover an introduction on the framework by creating a basic web application in both Java and Scala to get you started. The presentation will also cover javascript library integration and explain the philosophy behind the framework and give an honest analysis on the advantages and disadvantages of the framework. While this presentation is not interactive, all demos will be available on github for those that want to "play" along with their laptops.

Scala Koans - A new and fun way to learn a Scala programming language (Bring a Laptop)

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.

Testing In Scala

Most introductory programming books include a chapter on testing, seemingly as an afterthought. For the test-driven developer, that's a little too late. Some programmers approach a new programming language with a few test-cases to understand a concept. Others thrive under fire and want to hit the ground running in a new programming language by creating an application.

It just so happens that testing code in Scala is a great way to learn Scala, but also really good at testing Java code. This presentation started a book on how to use some of the greatest tools that you can use to test. This presentation will cover ScalaTest, Specs2, ScalaMock and ScalaCheck all in a triggered execution environment using SBT. For those that do not wish to use SBT, we will cover other options as well. Using these tools you may never want to use those plain jane java testing frameworks ever again. While this presentation is not interactive, all demos will be available on github for those that want to "play" along with their laptops.
