Packed with best practices, war stories, and hands-on tutorial exercises, "The Agile Samurai" slices away the fluff and theory that make other books un-agile.

Ruby on Rails enables the rapid production of high-quality web applications, allowing developers to focus on application creation while Rails manages the intricacies. This award-winning book has guided tens of thousands of developers, endorsed by the Rails core team. New users will find step-by-step instructions, while experienced developers will access comprehensive insider knowledge. The book has evolved alongside Rails, starting with a walkthrough of building a real application and delving into Rails features. This edition offers enhanced information on the Ruby language and elaborates on key concepts. It keeps pace with changing best practices, featuring examples of cookie-backed sessions, HTTP authentication, and Active Record-based forms, emphasizing the correct application of Rails. It also reflects the substantial functional and performance improvements of Ruby 1.9. Sam Ruby, a notable software developer and co-chair of the W3C HTML Working Group, brings his expertise, along with Dave Thomas, an author of the Agile Manifesto and "Programming Ruby," who understands both agility and Ruby. David Heinemeier Hansson, the creator of the Rails framework, also contributes to this essential resource for developers.

Provides information on the basics of Androd programming, covering such topics as designing the user interface, 2D graphics, multimedia, storing local data, SQL, OpenGL, and multi-touch.

Learn from legendary Japanese Ruby hacker Masatoshi Seki in this first English-language book on his Distributed Ruby library. Discover distributed computing, advanced Ruby concepts, and the philosophy of the Ruby way directly from the source. dRuby, part of the Ruby standard library for over a decade, allows seamless communication between distributed Ruby processes, showcasing its true power. This book uniquely addresses distributed and parallel programming for Ruby developers. Completely updated from its Japanese version, it includes three new chapters by Masatoshi-san, covering the design concepts of the dRuby library and providing step-by-step tutorials. You'll build various distributed applications, mastering distributed programming and advanced Ruby techniques like multithreading, object references, garbage collection, and security. Additionally, you'll learn advanced techniques for integrating dRuby with Masatoshi-san's other libraries, such as eRuby and Rinda, the Ruby version of the Linda distributed tuplespace system. The new chapters focus on integrating dRuby and eRuby, grounding you in parallel programming concepts with Rinda, and creating a full-text search system using Drip. Step by step, you'll gain mastery of dRuby and distributed computing. Familiarity with Ruby 1.9.2 or above is required, and all exercises were run on OS X, though compatibility with other operating systems is expected. Basic Ruby syntax
