1. Asynchronous and non-Blocking network frameworks have become a big deal: tools like node.js and BlueEyes have set the pattern for new projects. Yet they use an approach to their networking and architecture that is foreign to even many seasoned developers: callbacks instead of pure function calls can be daunting at first glance, yet powerful.

    As many Scala developers don't understand these approaches , we'll introduce Async/Non-Blocking IO and demonstrate both Netty & Raw NIO – and discuss strengths and weaknesses of each. Understanding the hows and why's of these approaches versus the more traditional synchronous can make a big difference for developers looking to choose the right approach for a new product.

    We'll also discuss patterns and concepts which can make these frameworks more powerful: The use of callbacks, Either[E, T] to pass errors, implicit tricks to simplify them and even the Iteratee pattern. Finally, we'll explore several ways to build synchronous looking APIs on top of these tools using varying approaches such as Continuations, Coroutines and even Actor based facades with Akka.

  2. In this session, we'll talk about Cassandra's data model, look at its query idioms, talk about how it functions in a cluster, and look at use cases in which it is an appropriate data storage solution for large-scale systems.

  3. The rise of Mobile and the diversity its technologies make exposing a RESTfull API the most crucial capability of any application and the key to its success. In the absence of widely adopted best practices and well-defined conventions, designing such an API is nothing but trivial. This presentation introduces the fundamentals of REST architecture, and discusses the principles of RESTfull design.
