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 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.

Book excerpt: A compelling dual-narrated tale from Jennifer Latham that questions how far we've come with race relations. Some bodies won't stay buried. Some stories need to be told. When seventeen-year-old Rowan Chase finds a skeleton on her family's property, she has no idea that investigating the brutal century-old murder will lead to a summer of painful discoveries about the present and the past. Nearly one hundred years earlier, a misguided violent encounter propels seventeen-year-old Will Tillman into a racial firestorm. In a country rife with violence against blacks and a hometown segregated by Jim Crow, Will must make hard choices on a painful journey towards self discovery and face his inner demons in order to do what's right the night Tulsa burns. Through intricately interwoven alternating perspectives, Jennifer Latham's lightning-paced page-turner brings the Tulsa race riot of 1921 to blazing life and raises important questions about the complex state of US race relations--both yesterday and today.

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.

Book excerpt: The Definitive Refactoring Guide, Fully Revamped for Ruby With refactoring, programmers can transform even the most chaotic software into well-designed systems that are far easier to evolve and maintain. What’s more, they can do it one step at a time, through a series of simple, proven steps. Now, there’s an authoritative and extensively updated version of Martin Fowler’s classic refactoring book that utilizes Ruby examples and idioms throughout–not code adapted from Java or any other environment. The authors introduce a detailed catalog of more than 70 proven Ruby refactorings, with specific guidance on when to apply each of them, step-by-step instructions for using them, and example code illustrating how they work. Many of the authors’ refactorings use powerful Ruby-specific features, and all code samples are available for download. Leveraging Fowler’s original concepts, the authors show how to perform refactoring in a controlled, efficient, incremental manner, so you methodically improve your code’s structure without introducing new bugs. Whatever your role in writing or maintaining Ruby code, this book will be an indispensable resource. This book will help you Understand the core principles of refactoring and the reasons for doing it Recognize “bad smells” in your Ruby code Rework bad designs into well-designed code, one step at a time Build tests to make sure your refactorings work properly Understand the challenges of refactoring and how they can be overcome Compose methods to package code properly Move features between objects to place responsibilities where they fit best Organize data to make it easier to work with Simplify conditional expressions and make more effective use of polymorphism Create interfaces that are easier to understand and use Generalize more effectively Perform larger refactorings that transform entire software systems and may take months or years Successfully refactor Ruby on Rails code

Download or read book Getting Clojure written by Russ Olsen and published by Pragmatic Bookshelf. This book was released on 2018-05-09 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behind every programming language lies a vision of how programs should be built. The vision behind Clojure is of a radically simple language framework holding together a sophisticated collection of programming features. Learning Clojure involves much more than just learning the mechanics of the language. To really get Clojure you need to understand the ideas underlying this structure of framework and features. You need this book: an accessible introduction to Clojure that focuses on the ideas behind the language as well as the practical details of writing code. Clojure attracts developers on the cutting edge and is arguably the best language for learning to program in the functional style without compromise. But this comes with a steep learning curve. Getting Clojure directly addresses this by teaching you how to think functionally as it teaches you the language. You'll learn about Clojure's powerful data structures and high-level functions, but you'll also learn what it means for a language to be functional, and how to think in Clojure's functional way. Each chapter of Getting Clojure takes a feature or two or three from the language, explains the syntax and the mechanics behind that feature so that you can make it work before digging into the deeper questions: What is the thinking behind the feature? And how does it fit in with the rest of the language? In Getting Clojure you'll learn Clojure's very simple syntax, but you'll also learn why that syntax is integral the way the language is constructed. You'll discover that most data structures in Clojure are immutable, but also why that leads to more reliable programs. And you'll see how easy it is to write Clojure functions and also how you can use those functions to build complex and capable systems. With real-world examples of how working Clojure programmers use the language, Getting Clojure will help you see the challenges of programming through the eye of experienced Clojure developers. What You Need: You will need to some background in programming. To follow along with the examples in the book, you will need Java 6 or new, Clojure 1.8 or 1.9, and Leiningen 2.

Download or read book Ruby Oprah s Book Club 2 0 written by Cynthia Bond and published by Hogarth. This book was released on 2015-02-10 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: A New York Times bestseller and Oprah Book Club 2.0 selection, the epic, unforgettable story of a man determined to protect the woman he loves from the town desperate to destroy her. This beautiful and devastating debut heralds the arrival of a major new voice in fiction. Ephram Jennings has never forgotten the beautiful girl with the long braids running through the piney woods of Liberty, their small East Texas town. Young Ruby Bell, “the kind of pretty it hurt to look at,” has suffered beyond imagining, so as soon as she can, she flees suffocating Liberty for the bright pull of 1950s New York. Ruby quickly winds her way into the ripe center of the city—the darkened piano bars and hidden alleyways of the Village—all the while hoping for a glimpse of the red hair and green eyes of her mother. When a telegram from her cousin forces her to return home, thirty-year-old Ruby finds herself reliving the devastating violence of her girlhood. With the terrifying realization that she might not be strong enough to fight her way back out again, Ruby struggles to survive her memories of the town’s dark past. Meanwhile, Ephram must choose between loyalty to the sister who raised him and the chance for a life with the woman he has loved since he was a boy. Full of life, exquisitely written, and suffused with the pastoral beauty of the rural South, Ruby is a transcendent novel of passion and courage. This wondrous page-turner rushes through the red dust and gossip of Main Street, to the pit fire where men swill bootleg outside Bloom’s Juke, to Celia Jennings’s kitchen, where a cake is being made, yolk by yolk, that Ephram will use to try to begin again with Ruby. Utterly transfixing, with unforgettable characters, riveting suspense, and breathtaking, luminous prose, Ruby offers an unflinching portrait of man’s dark acts and the promise of the redemptive power of love. Ruby was a finalist for the PEN America Robert Bingham Debut Novel Award, a Barnes & Noble Discover Great New Writers selection, and an Indie Next Pick.
