The dRuby Book
dRuby has been part of the Ruby standard library for more than a decade, yet few know the true power of the gem. Completely written in Ruby, dRuby enables you to communicate between distributed Ruby processes as if there were no boundaries between processes. This is one of the few books that covers distributed and parallel programming for Ruby developers.

The dRuby Book has been completely updated and expanded from its Japanese version, with three new chapters written by Masatoshi-san. You'll find out about the design concepts of the dRuby library, and walk through step-by-step tutorial examples. By building various distributed applications, you'll master distributed programming as well as advanced Ruby techniques such as multithreading, object references, garbage collection, and security. Then you'll graduate to advanced techniques for using dRuby with Masatoshi-san's other libraries, such as eRuby and Rinda - the Ruby version of the Linda distributed tuplespace system. In the three new chapters, you'll see how to integrate dRuby and eRuby, get a thorough grounding in parallel programming concepts with Rinda, and create a full text search system using Drip. more »

If you're a Cocoa developer, you'll learn how to improve your productivity with MacRuby. more »
The Joy of Clojure
If you've seen how dozens of lines of Java or Ruby can dissolve into just a few lines of Clojure, you'll know why the authors of this book call it a "joyful language". Clojure is a dialect of Lisp that runs on the JVM. It combines the nice features of a scripting language with the powerful features of a production environment - features like persistent data structures and clean multithreading that you'll need for industrial-strength application development.

The Joy of Clojure goes beyond just syntax to show you how to write fluent and idiomatic Clojure code. You'll learn a functional approach to programming and will master Lisp techniques that make Clojure so elegant and efficient. The book gives you easy access to hard soft ware areas like concurrency, interoperability, and performance. And it shows you how great it can be to think about problems the Clojure way. more »
Rails 3 in Action
Rails 3 is a full stack, open source web framework powered by Ruby and this book is an introduction to it. Whether you're just starting or you have a few cycles under your belt, you'll appreciate the book's guru's-eye-view of idiomatic Rails programming.

You'll master Rails 3.1 by developing a ticket tracking application that includes RESTful routing, authentication and authorization, state maintenance, file uploads, email, and more. You'll also explore powerful features like designing your own APIs and building a Rails engine. You will see Test Driven Development and Behavior Driven Development in action throughout the book, just like you would in a top Rails shop. more »
Exploring Everyday Things with R and Ruby
If you're curious about how things work, this fun and intriguing guide will help you find real answers to everyday problems. By using fundamental math and doing simple programming with the Ruby and R languages, you'll learn how to model a problem and work toward a solution.

All you need is a basic understanding of programming. After a quick introduction to Ruby and R, you'll explore a wide range of questions by learning how to assemble, process, simulate, and analyze the available data. You'll learn to see everyday things in a different perspective through simple programs and common sense logic. Once you finish this book, you can begin your own journey of exploration and discovery. more »
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. more »

Ruby on Rails Tutorial, 2nd Edition
Using Rails, developers can build web applications of exceptional elegance and power. Although its remarkable capabilities have made Ruby on Rails one of the world's most popular web development frameworks, it can be challenging to learn and use. Ruby on Rails Tutorial, Second Edition, is the solution. Best-selling author and leading Rails developer Michael Hartl teaches Rails by guiding you through the development of your own complete sample application using the latest techniques in Rails web development. The updates to this edition include all-new site design using Twitter's Bootstrap; coverage of the new asset pipeline, including Sprockets and Sass; behavior-driven development (BDD) with Capybara and RSpec; better automated testing with Guard and Spork; roll your own authentication with has_secure_password; and an introduction to Gherkin and Cucumber. more »
Rails AntiPatterns
As developers worldwide have adopted the powerful Ruby on Rails web framework, many have fallen victim to common mistakes that reduce code quality, performance, reliability, stability, scalability, and maintainability. Rails AntiPatterns identifies these widespread Rails code and design problems, explains why they're bad and why they happen - and shows exactly what to do instead.

The book is organized into concise, modular chapters - each outlines a single common AntiPattern and offers detailed, cookbook-style code solutions that were previously difficult or impossible to find. more »
