Deploying with JRuby
JRuby deployments have fewer moving parts and consume less memory than traditional Ruby deployments, but to deploy your apps on the JVM, you need to learn some new approaches. This book introduces you to three JRuby deployment strategies that will give you the performance and scalability you need while letting you use the language you love. You'll start by porting an existing application to JRuby preparing the app to take advantage of the JVM platform. Then you'll use Vagrant and Puppet to build a virtual production environment so you have a stable, reproducible place to explore JRuby deployment. ...

Puppet Types and Providers
Puppet's true power exists in the simple resource model it uses to manage the state of complex operating systems. This concise guide shows you how to extend that model and implement custom functionality on top of Puppet by working with the type and provider APIs. Two experts from Puppet Labs explain the concepts behind these APIs, and provide instructions and examples to help you write your own fully functional types and providers. You'll also delve into Puppet's source code to get a better understanding of how types and providers are implemented internally. If you're familiar with basic Puppet concepts, you're ready to get started. ...

RubyMotion
Developers interested in native iOS app development have been restricted to the limits of Objective-C and Xcode - until RubyMotion came along. RubyMotion enables you do full iOS development using Ruby. You have access to familiar tools such as Rake and RubyGems and can compile Ruby code into native applications. RubyMotion even comes with a Ruby console useful for live coding and interactive debugging. And since RubyMotion is built on top of the Objective-C runtime, you can use all of Apple's libraries and most third-party code alongside Ruby classes. ...

Practical Object-Oriented Design in Ruby
Ruby's widely admired ease of use has a downside: Too many Ruby and Rails applications have been created without concern for their long-term maintenance or evolution. The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. ...

Continuous Testing
Feedback. We're always telling you that you need feedback, with a short feedback gap the time it takes to get feedback on your decisions, your code, your designs. Well, what if you narrowed the feedback gap to near zero while coding? You'd have continuous testing, a powerful idea that lets you fix bugs while they're still small and fresh. Continuous Testing shows you how to use a combination of tests, tools, and techniques to immediately detect problems in code, before they spread. ...
