Tutorial: Elixir

If you think functional languages are a big pain in the rear but you still need the tools for building concurrent applications and multi-core programs, then Elixir is your thing! Combining the best features of Ruby and Erlang with brilliant ideas of its own, Elixir might just change the way you write software forever. This tutorial introduces you to Elixir, the best of both worlds, Ruby’s unrivalled syntactic beauty with the power of Erlang’s semantics.

Elixir is a dynamic language with flexible syntax based on Ruby and macro support. It is built on top of the Erlang VM, an unrivalled environment for massive scalability, concurrency, distribution, and fault tolerance. It comes with built-in support for metaprogramming, provides first-class support for pattern matching, polymorphism via protocols (similar to Clojure’s), aliases and associative data structures (called dicts or hashes in other programming languages).

In this tutorial, we cover:

- Basic and Sequential Elixir

- Concurrent Programming

- Meta-Programming

Weaving OpenFlow Together with LOOM

LINC and LOOM are an open source OpenFlow software switch and controller. This talk focuses on LOOM, the controller. We'll start with where LOOM fits into the network architecture, the goals of the project, and its design direction. Then we'll dive into the details of how to use the LOOM libraries to write your own OpenFlow controllers.

Talk objectives:

- Introduce LOOM and the LOOM libraries.

Target audience:

- Anyone interested in experimenting with the OpenFlow protocol to control OpenFlow switches.
