1. It's almost inevitable in any Ruby Project - you hit that stage where your logic starts getting more complex, you start doing more stuff that needs to happen but doesn't have to happen in the foreground - or you just want things to be faster.

    You move your logic out into workers and do the work in the background.

    This talk is going to be all about Sidekiq - a threaded background job implementation written in Ruby - and, in two parts: How you can use it and how you can bend it to your will.

    Part 1: Intro to Sidekiq

    The boring: a brief introduction to sidekiq, how it works - what it's advantages are. The stuff you need to know about it, why it's useful to consider - even if you're using CRuby / MRI.

    Part 2: Hacking Sidekiq

    The cooler part - once you know what Sidekiq is, I'm going to show how you can use Sidekiq in your product, how you can extend it and bend it to your will. I'll go into how it implements itself in ruby land and how it interacts with the Redis.

    I'll show how you can use the existing middleware (and write your own) to add behaviour to your code, patterns we've found useful for implementing and testing workers as well as the even more interesting side - using Lua support in Redis to implement stuff in Sidekiq.

    I want to encourage developers to look at extending their tool set to work better with not just ruby - to become comfortable with how they work internally (e.g. you should really learn how to love redis) and what you really need to be careful of (e.g. bugs that manifest when the site is under less load than usual - a real world example of going too far).

    Finally, I'll end with an important question: Why not just use a proper message queue?

  2. So you want to be an open source contributor? Think you can handle supporting multiple rubies, tracking down weird bugs, stomaching all that the wider developer eco system can throw at you? Well good reader, I can tell you stories that will turn your stomach, and blind your eyes.

    Let me take you on a journey deep into the depths of open source triage and follow the kind of madness that comes from tracking down bugs across differing versions of Ruby and VMs.

    Finally let me entertain you with stories of the perils of dogfooding your testing framework, and throw in some stories about the kind of hackery you can commit with a bit of mischievousness.

  3. Smalltalk is an object-oriented, dynamically typed, reflective programming language. Smalltalk is a "pure" object-oriented programming language, meaning that, unlike Java and C++, there is no difference between values which are objects and values which are primitive types. In Smalltalk, primitive values such as integers, booleans and characters are also objects, in the sense that they are instances of corresponding classes, and operations on them are invoked by sending messages.

    Sound familiar?

    Smalltalk leaves a long shadow on the programming landscape and can be considered both as an ancestor and influence on the design of Ruby. This talk introduces Smalltalk to Rubyists and covers software principles which can be applied to Ruby applications, both large and small.

    Topics include:

    Brief overview
    Design
    Expressions
    Literals
    Messages
    Patterns
    Reflection

  4. You probably use Ruby everyday, so why not use Ruby to automate some common tasks? What if you could spin up an EC2 instance and have it automatically configure your web server, database, users, and more? What if you could effectively capture and replicate your production environments reliably and consistently? What if you could then give developers production-like environments as Virtual Machines, with no additional work? What if you could set up your new laptop with multiple Ruby versions, your favourite software, and even change the desktop background - from a single command? The good news is - you can!

    Chef is a configuration management and automation tool that solves these problems and many more. In this talk, you'll learn common just how easy it is to capture your infrastructure in Chef. Save time and money by using Chef's Ruby DSL to "define" your laptop.

    How many times have you bought a new laptop and realise just how much stuff you installed over the years? If you're using Chef, run a single command
