Learn Enough Ruby To Be Dangerous

Download or read book RailsSpace written by Michael Hartl and published by Addison-Wesley Professional. This book was released on 2007-07-20 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruby on Rails is fast displacing PHP, ASP, and J2EE as the development framework of choice for discriminating programmers, thanks to its elegant design and emphasis on practical results. RailsSpace teaches you to build large-scale projects with Rails by developing a real-world application: a social networking website like MySpace, Facebook, or Friendster. Inside, the authors walk you step by step from the creation of the site's virtually static front page, through user registration and authentication, and into a highly dynamic site, complete with user profiles, image upload, email, blogs, full-text and geographical search, and a friendship request system. In the process, you learn how Rails helps you control code complexity with the model-view-controller (MVC) architecture, abstraction layers, automated testing, and code refactoring, allowing you to scale up to a large project even with a small number of developers. This essential introduction to Rails provides A tutorial approach that allows you to experience Rails as it is actually used A solid foundation for creating any login-based website in Rails Coverage of newer and more advanced Rails features, such as form generators, REST, and Ajax (including RJS) A thorough and integrated introduction to automated testing The book's companion website provides the application source code, a blog with follow-up articles, narrated screencasts, and a working version of the RailSpace social network.

Download or read book Practical Object-oriented Design in Ruby written by Sandi Metz and published by Pearson Education. This book was released on 2013 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Complete Guide to Writing More Maintainable, Manageable, Pleasing, and Powerful Ruby Applications 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. This book focuses 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. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

Download or read book Effective Ruby written by Peter J. Jones and published by Pearson Education. This book was released on 2015 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you're an experienced Ruby programmer, Effective Ruby will help you harness Ruby's full power to write more robust, efficient, maintainable, and well-performing code. Drawing on nearly a decade of Ruby experience, Peter J. Jones brings together 48 Ruby best practices, expert tips, and shortcuts--all supported by realistic code examples. Jones offers practical advice for each major area of Ruby development, from modules to memory to metaprogramming. Throughout, he uncovers little-known idioms, quirks, pitfalls, and intricacies that powerfully impact code behavior and performance. Each item contains specific, actionable, clearly organized guidelines; careful advice; detailed technical arguments; and illuminating code examples. When multiple options exist, Jones shows you how to choose the one that will work best in your situation. Effective Ruby will help you systematically improve your code--not by blindly following rules, but by thoroughly understanding Ruby programming techniques. Key features of this concise guide include How to avoid pitfalls associated with Ruby's sometimes surprising idiosyncrasies What you should know about inheritance hierarchies to successfully use Rails (and other large frameworks) How to use misunderstood methods to do amazingly useful things with collections Better ways to use exceptions to improve code reliability Powerful metaprogramming approaches (and techniques to avoid) Practical, efficient testing solutions, including MiniTest Unit and Spec Testing How to reliably manage RubyGem dependencies How to make the most of Ruby's memory management and profiling tools How to improve code efficiency by understanding the Ruby interpreter's internals

Available in PDF, EPUB and Kindle. Book excerpt: Book one in the hit series that's soon to be a major motion picture starring Amandla Stenberg and Mandy Moore--now with a stunning new look and an exclusive bonus short story featuring Liam and his brother, Cole. When Ruby woke up on her tenth birthday, something about her had changed. Something alarming enough to make her parents lock her in the garage and call the police. Something that got her sent to Thurmond, a brutal government "rehabilitation camp." She might have survived the mysterious disease that killed most of America's children, but she and the others emerged with something far worse: frightening abilities they cannot control. Now sixteen, Ruby is one of the dangerous ones. But when the truth about Ruby's abilities--the truth she's hidden from everyone, even the camp authorities--comes out, Ruby barely escapes Thurmond with her life. On the run, she joins a group of kids who escaped their own camp: Zu, a young girl haunted by her past; Chubs, a standoffish brainiac; and Liam, their fearless leader, who is falling hard for Ruby. But no matter how much she aches for him, Ruby can't risk getting close. Not after what happened to her parents. While they journey to find the one safe haven left for kids like them--East River--they must evade their determined pursuers, including an organization that will stop at nothing to use Ruby in their fight against the government. But as they get closer to grasping the things they've dreamed of, Ruby will be faced with a terrible choice, one that may mean giving up her only chance at a life worth living.
