Download or read book Design Patterns in Ruby Adobe Reader written by Russ Olsen and published by Pearson Education. This book was released on 2007-12-10 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: Praise for Design Patterns in Ruby "Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly encounter. Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth of experience available to Ruby developers for their own daily work." —Steve Metsker, Managing Consultant with Dominion Digital, Inc. "This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting to overly technical explanations. Written in a precise, yet almost informal style, this book covers enough ground that even those without prior exposure to design patterns will soon feel confident applying them using Ruby. Olsen has done a great job to make a book about a classically 'dry' subject into such an engaging and even occasionally humorous read." —Peter Cooper "This book renewed my interest in understanding patterns after a decade of good intentions. Russ picked the most useful patterns for Ruby and introduced them in a straightforward and logical manner, going beyond the GoF's patterns. This book has improved my use of Ruby, and encouraged me to blow off the dust covering the GoF book." —Mike Stok "Design Patterns in Ruby is a great way for programmers from statically typed objectoriented languages to learn how design patterns appear in a more dynamic, flexible language like Ruby." —Rob Sanheim, Ruby Ninja, Relevance Most design pattern books are based on C++ and Java. But Ruby is different—and the language's unique qualities make design patterns easier to implement and use. In this book, Russ Olsen demonstrates how to combine Ruby's power and elegance with patterns, and write more sophisticated, effective software with far fewer lines of code. After reviewing the history, concepts, and goals of design patterns, Olsen offers a quick tour of the Ruby language—enough to allow any experienced software developer to immediately utilize patterns with Ruby. The book especially calls attention to Ruby features that simplify the use of patterns, including dynamic typing, code closures, and "mixins" for easier code reuse. Fourteen of the classic "Gang of Four" patterns are considered from the Ruby point of view, explaining what problems each pattern solves, discussing whether traditional implementations make sense in the Ruby environment, and introducing Ruby-specific improvements. You'll discover opportunities to implement patterns in just one or two lines of code, instead of the endlessly repeated boilerplate that conventional languages often require. Design Patterns in Ruby also identifies innovative new patterns that have emerged from the Ruby community. These include ways to create custom objects with metaprogramming, as well as the ambitious Rails-based "Convention Over Configuration" pattern, designed to help integrate entire applications and frameworks. Engaging, practical, and accessible, Design Patterns in Ruby will help you build better software while making your Ruby programming experience more rewarding.

Download or read book The Impeccable Integrity of Ruby R written by Moni Mohsin and published by Penguin UK. This book was released on 2020-12-21 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruby Rauf is an idealistic, industrious scholarship student with a fixed plan. She is going to ace her exams and get a decent job so she never has to suffer the daily degradation of poverty again. Yet, when she meets the compelling actor-turned-politician Saif Haq, her world is upended. Dazzled by his charisma, inspired by his zeal, she quits her degree midway to join his campaign as his social media manager. Ruby soon discovers that politics, even with a leader as upright as Saif Haq, is a moral minefield. Diligent, sincere but desperately naïve, Ruby longs to do the right thing but struggles at first to square her innate integrity with the difficult choices her job demands. As she wades deeper into the quagmire of political intrigue and the savage world of social media, her values grow more flexible, her methods more ruthless. She out-thinks allies and rivals to deliver brilliant results. Resented and admired by her colleagues, favoured by Saif, Ruby appears unstoppable-until one day when Saif asks her to prove her loyalty by making the most painful sacrifice of all. With quicksilver dialogue, shrewd political insight and a thoughtful take on the MeToo debate, this sparkling novel reveals Moni Mohsin on top satirical form.

Download or read book Eloquent Ruby written by Russ Olsen and published by Addison-Wesley Professional. This book was released on 2011-02-07 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: It’s easy to write correct Ruby code, but to gain the fluency needed to write great Ruby code, you must go beyond syntax and absorb the “Ruby way” of thinking and problem solving. In Eloquent Ruby, Russ Olsen helps you write Ruby like true Rubyists do–so you can leverage its immense, surprising power. Olsen draws on years of experience internalizing the Ruby culture and teaching Ruby to other programmers. He guides you to the “Ah Ha!” moments when it suddenly becomes clear why Ruby works the way it does, and how you can take advantage of this language’s elegance and expressiveness. Eloquent Ruby starts small, answering tactical questions focused on a single statement, method, test, or bug. You’ll learn how to write code that actually looks like Ruby (not Java or C#); why Ruby has so many control structures; how to use strings, expressions, and symbols; and what dynamic typing is really good for. Next, the book addresses bigger questions related to building methods and classes. You’ll discover why Ruby classes contain so many tiny methods, when to use operator overloading, and when to avoid it. Olsen explains how to write Ruby code that writes its own code–and why you’ll want to. He concludes with powerful project-level features and techniques ranging from gems to Domain Specific Languages. A part of the renowned Addison-Wesley Professional Ruby Series, Eloquent Ruby will help you “put on your Ruby-colored glasses” and get results that make you a true believer.

Download or read book Jericho written by Robert Ruby and published by Henry Holt and Company. This book was released on 2014-11-11 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a place both mythic and all too real, a place thought to be the site of one of our oldest human settlements and known to be a center of ancient cultures and annihilating conflicts. It sits at the bottom of a malarial valley, the lowest place on the surfact of the earth--"the overheated, earthen basement of the world," as Robert Ruby describes it. And yet, long before the world's modern religions began scrapping over its bones, Jericho was home to waves of colonization and floods of destruction. Fought over by the succeeding epochs of ancestors, the place we call Jericho is as old as the first remnants dated at 9,000 B.C.--and as current as the daily headlines. In this unorthodox biography of the first eleven thousand years in the life of a legend, Robert Ruby takes us back through time to those early settlements, then forward to the often crude but ultimately successful latter-day attempts to locate Jericho, to unearth and map and catalog its history. Beginning with the geography of place, he weaves together his own intimate knowledge of modern-day Jericho with stories of the lives and work of those explorers and archaeologists of the past whose courage often bordered on madness and whose dedication sometimes seemed the purest kind of human folly. Soldiers, scholars, engineers, adventurers--dilettantes and professionals alike, they were all dreamers drawn to this parched and dusty spot where so much of human history took place. Matching biblical accounts to araeological evidence, sifting myth from science, phantoms from reality, Robert Ruby teases out the complex strata of the past, helping us to make sense of what exists today. With the flair of a novelist and the enthusiasm of an amateur archaeologist, he offers a tale that is part detection, part epic adventure. Above all, he gives us a work of great literary panache: witty, fact-filled, and uterly, subversively compelling.
