     All the Starcraft n00bs know exactly how to win. They take all the resources they can, and upgrade all the expensive tech and think to themselves, "soon i'll be unstoppable". Unfortunately "eventually unstoppable" is the same as dead right now. This type of premature optimization and abstraction can kill a business faster than not being able to scale. In this talk we'll take a look at how to pick the right unit composition (databases vs. NoSQL), balance your macro and micro (scale out vs. up), and choose the right race (programing language). If you've never played Starcraft, and can't tell a ultralisk from a firebat, don't worry there's still a room for you. Sorry, no Zerg allowed.

     While Node.js is the hot new kid on the block, evented libraries like EventMachine for Ruby and Twisted for Python have existed for a long time. When does it make sense to use one over the other? What are the advantages and disadvantages to using node over ruby? In this talk, you will learn how to get the same power of concurrency enjoyed by Node.js while continuing to write in the language you know and love. Topics covered will include pubsub with redis or faye, building evented rack applications, and running evented applications alongside existing Rails apps.

     I started programming Rails on Windows in 2008. The experience was not the best but I still made the best of it. Fast-forward to 2012 and because of tools like RailsInstaller, Windows users have things almost easier than Mac/Linux. This talk will focus on some of the best-practices that I've found when using Windows for Ruby on Rails development and is really geared toward helping people get started programming Rails in a Windows environment. The talk is sexy and it knows it so be prepared to laugh and have fun.

     As applications grow, dependency management becomes painful, tests get slower, and development becomes less joyful. Breaking up the application into services can be a great solution to these problems, but not every team is ready to leap fully into a SOA. Carson is Zendesk's compromise to this problem. It's a Rails 3 engine host: an application that contains only a Gemfile full of engines and some configuration. In this talk we'll explore the benefits and drawbacks of delivering features as engines and how this approach can act as a stepping stone from big-ball-of-mud architectures to service-oriented ones.

But test doubles can be useful guides, highlighting design issues and in our application. By treating them as companions, we can find our way to long-term maintainable designs and effective test suites.

     There’s nothing more frustrating for a developer than spending months creating an application and then having it fail because of performance issues. That’s why integrating application performance management into each step of the development lifecycle is critical to your application’s success. Of course, easy-to-use tools for performance management are rare, and often prohibitively expensive. Not to mention that they don’t reflect actual user behavior. In order for APM solutions to succeed in the Ruby community, they must be affordable, easy to use, require no scripting; and easily integrate into the development process – be it a PaaS system such as Heroku or some other delivery system. From idea formation to final delivery, Rubyists must know their product is working every step of the way.

     Open source is hard but it gets much easier with a community backing you. I tried many approaches while developing fog, and thankfully, the resulting community is amazing. Now I'm doing my best to apply the same principles to the Heroku CLI and other open source projects. I make mistakes and often get lucky, but I have learned a lot about fostering community in the process. This session distills some of my techniques and explains how you can help build community around your favorite projects.

But there is a lot more to a "good" library than just the API: proper logging, flexible configuration, a sane exception hierarchy, and useful documentation, just to name a few. How do we do these things properly? What pros/cons are there to different approaches? Unfortunately, no one really talks about these things, despite being very important to the overall feel of a library.
