Few completed Rails apps are architecturally simple. As soon as you grow, you find yourself using multiple subsystems and machines to scale, creating new headaches in configuration management. Help is at hand! This tutorial introduces Chef, a modern Ruby-based open source approach to systems integration. Chef lets you manage your servers by writing code, not running commands.

Future web apps will be built on the client-server model: faster, more fluid, desktop-like apps that cannot be fully realized with traditional Rails techniques for building browser views. But Rails is the perfect server framework to integrate with SproutCore, an exciting new framework for building web browser clients. Students will build a full-fledged client-server app using both frameworks.

Used appropriately, mock objects are a powerful design tool that can lead to highly maintainable applications. Used in the wrong context, they can lead to painfully brittle test suites. Attendees will leave this session with more insight into mock objects, and a better handle on when it makes sense to use them.

Agora Games has spent a significant amount of time developing the virtualized infrastructure behind Call of Duty: World at War, centering around a Rails stack that tracks the statistics for millions of players. In this talk, we'll describe how we built this architecture, how it varies from a more traditional Rails infrastructure, and the lessons we've learned doing so.

The way we deploy ruby apps is changing. This is a a rare opportunity to discuss issues and ideas in real time, directly with the key people from each part of the stack, all in one room.
This is truly a killer line-up: Marc-André Cournoyer (Thin), Christian Neukirchen (Rack), Ryan Tomayko (Rack::Cache, Sinatra), Blake Mizerany (Sinatra), Adam Wiggins and James Lindenbaum (Heroku)

This talk explores what makes Test Driven Development really work by showing what happens where the process breaks down, focusing on rapid feedback as the key to asuccessful test-driven process. It also creates a vocabulary for talking about malformed test processes.

Cucumber is a novel tool for Behaviour Driven Development. While early BDD tools like RSpec and Shoulda are geared towards programmers, classes and objects, Cucumber nicely fills the communication gap between customers, programmers and testers. This session will change how you approach requirements and testing of Rails applications.

How can you make sure that your beautiful Rails code doesn't degrade over time as more people join a project and deadlines loom? Well, there are tools to measure test coverage, code complexity, churn, bad practices, duplication, and code smell. And all of these various open source projects have been mashed together in metric_fu - a Ruby gem that makes measuring the quality of your code easy.

Rails3 is the result of the Merb and Rails merger. While the usual ActiveRecord/ERB/Prototype/Test::Unit full stack is still the default, Rails3 now let you step off of the golden path.
Learn more about alternative stack components, when and why to use them by looking at concrete examples.

You know Rails 2.x is fast, but your application is still slow. This session goes beyond the basics and gets into advanced areas such as optimizing complex has_many/belongs_to relationships, template rendering, browser performance, database use. The session covers performance-oriented development processes and tools. Special topic: optimizing for deployment on dedicated, VPS and shared hosting.

HTTP's basic caching mechanisms have been around for almost a decade and still their advantages and limitations are still not well understood. In this talk, we provide a clear and simple explanation of how HTTP caching works, put forth a system for classifying response cacheability, and argue that HTTP caching should be a fundamental aspect of resource design.

The benefits of Rack support in Rails have become increasingly obvious; Rails Metal and integrating multiple Rack applications have made possible architectures that were impractical before, and some long-held opinions are ripe for change. In this session, we'll see how to set up this integration and explore real examples of how it can be used—including the rehabilitation of page caching.

Automated code quality tools are just starting to become popular in the Ruby and Rails world, even though they've been around a long time in the Java and .NET communities. Learn what the tools are, and how to use them to improve the consistency, testability and overall quality of your Ruby and Rails applications.

One of the hottest new features in Rails 3 is the ability to embed a Rails application in another Rails application. This allows the development of components that range from user authentication to a fully featured forum. In this talk, Yehuda and Carl will give an in-depth tutorial by building a CMS, creating a gem out of it, and integrating it into another app.
