Book Synopsis Design Patterns in Ruby (Adobe Reader) by : Russ Olsen
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.

Readers are introduced to the many facets of Ruby, including the language's history, the basics of operation, and implementation of the system's application framework, Ruby on Rails. Discussions of less than optimal aspects of the system and user concerns ensure that the coverage is well-rounded. The accessible text is as easy to understand as Ruby itself. Get to know Ruby!
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.

Book Synopsis Ruby Performance Optimization by : Alexander Dymo
Download or read book Ruby Performance Optimization written by Alexander Dymo and published by Pragmatic Bookshelf. This book was released on 2015-11-19 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: You don't have to accept slow Ruby or Rails performance. In this comprehensive guide to Ruby optimization, you'll learn how to write faster Ruby code--but that's just the beginning. See exactly what makes Ruby and Rails code slow, and how to fix it. Alex Dymo will guide you through perils of memory and CPU optimization, profiling, measuring, performance testing, garbage collection, and tuning. You'll find that all those "hard" things aren't so difficult after all, and your code will run orders of magnitude faster. This is the first book ever that consolidates all the Ruby performance optimization advice in one place. It's your comprehensive guide to memory optimization, CPU optimization, garbage collector tuning, profiling, measurements, performance testing, and more. You'll go from performance rookie to expert. First, you'll learn the best practices for writing Ruby code that's easy not only on the CPU, but also on memory, and that doesn't trigger the dreaded garbage collector. You'll find out that garbage collection accounts for 80% of slowdowns, and often takes more than 50% of your program's execution time. And you'll discover the bottlenecks in Rails code and learn how selective attribute loading and preloading can mitigate the performance costs of ActiveRecord. As you advance to Ruby performance expert, you'll learn how profile your code, how to make sense out of profiler reports, and how to make optimization decisions based on them. You'll make sure slow code doesn't creep back into your Ruby application by writing performance tests, and you'll learn the right way to benchmark Ruby. And finally, you'll dive into the Ruby interpreter internals to really understand why garbage collection makes Ruby so slow, and how you can tune it up. What You Need: Some version of Ruby. The advice from this book applies to all modern Ruby versions from 1.9 to 2.2. 80% of the material will also be useful for legacy Ruby 1.8 users, and there is 1.8-specific advice as well.

Book Synopsis Ruby (Oprah's Book Club 2.0) by : Cynthia Bond
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.

Available in PDF, EPUB and Kindle. Book excerpt: That’s Why We Don’t Eat Animals uses colorful artwork and lively text to introduce vegetarianism and veganism to early readers (ages six to ten). Written and illustrated by Ruby Roth, the book features an endearing animal cast of pigs, turkeys, cows, quail, turtles, and dolphins. These creatures are shown in both their natural state—rooting around, bonding, nuzzling, cuddling, grooming one another, and charming each other with their family instincts and rituals—and in the terrible conditions of the factory farm. The book also describes the negative effects eating meat has on the environment. A separate section entitled “What Else Can We Do?” suggests ways children can learn more about the vegetarian and vegan lifestyles, such as:“Celebrate Thanksgiving with a vegan feast” or “Buy clothes, shoes, belts, and bags that are not made from leather or other animal skins or fur.” This compassionate, informative book offers both an entertaining read and a resource to inspire parents and children to talk about a timely, increasingly important subject.
