Ruby in Practice by Jeremy McAnally,Assaf Arkin Pdf

Ruby in Practice increases your productivity by showing you specific Ruby techniques you can use in your projects. The book offers detailed strategies for using Ruby in a large-scale environment. You'll see concrete examples of integration, messaging, web development, and databases, all presented in a clear Problem/Solution format. This book won't help you push your deadline back, but it will help you get the job done in less time. Above all, Ruby in Practice is a practical book for developers who want an in depth understanding of the Ruby language and its toolset. The book is divided into three major parts. The first part concentrates on issues that developers face both from within their organizations and from their peers. The authors weigh the costs and benefits of using Ruby in enterprise development projects, the over-riding theme being that every developer should always aim to use the right tool for any particular job. The authors then examine the pros and cons of developing with Ruby, and where appropriate, compare Ruby to other languages, both conceptually and in code. The second part discusses techniques for communication and integration of systems. The authors describe how libraries and techniques are used to facilitate messaging, web development and communication automation. They also focus on how the strategies in the first section can be used with these libraries to make development more flexible and efficient. The last part shows how to manage data and integrate with existing data using Ruby. The authors describe techniques for using existing Ruby libraries that either replace popular Java libraries or can interface with existing data in a different way. They go on to show you how strategies covered in the first section can be used to enable Ruby to interact with existing assets or to build new data systems. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.

Eloquent Ruby by Russ Olsen Pdf

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.

Practical Object-Oriented Design in Ruby by Sandi Metz Pdf

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. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus 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

Acute Reactions by Ruby Lang Pdf

The man with allergies never gets the girl, at least according to the movies - and Portland restaurateur Ian Zamora wants to be the guy who gets the girl. So to rid himself of the sensitivities brought on by his sometimes-girlfriend's cat, he makes an appointment with allergist Petra Lale. But he suddenly finds himself acutely attracted to the very woman who is supposed to be helping him take care of his problem. Petra's intrigued by Ian's quiet strength and sexy body, but her solo practice is new and struggling. She can't afford to compromise her ethics - or risk her medical license - by dating a patient. Falling in love certainly wasn't this doctor's order. She tries to stay away from Ian, but fate, and her weak willpower, keep bringing them back together. Do two career-driven people with inexperienced hearts stand a chance of finding the right prescription for love? Sensuality Level: Sensual

My Body, My Earth by Ruby Gibson Pdf

Within each body is an archaeological site that holds the details and wisdom of our extraordinary life story, composed of generational, spiritual, and personal experiences. Historical amnesia locks these stories in the body, manifesting as pain, disease, addictions, emotional patterns, and repetitive circumstances. Somatically excavating your personal legend unearths memories of the past that can be reconciled and healed in order to create a new myth-for your body and for your Earth "My Body, My Earth provides a detailed and eloquent rationale and description for how this remarkable technique works, both as a therapeutic model and a self-help manual. It is a major contribution to the burgeoning literature in the field of somatic psychology."-Robert Scaer, M.D., author. The Body Bears the Burden: Trauma, Dissociation and Disease, and The Trauma Spectrum: Hidden Wounds and Human Resiliency "A remarkable incursion into one of the deepest of all mysteries: the hidden memories that are locked into the fibers of our bodies. This book is an impressive and extremely helpful guide to reuniting the conscious and unconscious aspects of the mind."-Richard Smoley, author of Conscious Love and Inner Christianity

Design Patterns in Ruby by Russ Olsen Pdf

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.

Ruby by Example by Kevin C. Baird Pdf

There may be no better way to learn how to program than by dissecting real, representative examples written in your language of choice. Ruby by Example analyzes a series of Ruby scripts, examining how the code works, explaining the concepts it illustrates, and showing how to modify it to suit your needs. Baird's examples demonstrate key features of the language (such as inheritance, encapsulation, higher-order functions, and recursion), while simultaneously solving difficult problems (such as validating XML, creating a bilingual program, and creating command-line interfaces). Each chapter builds upon the previous, and each key concept is highlighted in the margin to make it easier for you to navigate the book. You'll learn how to: –Use the interactive Ruby shell (irb) to learn key features of the language –Extend Ruby using RubyGems, the Ruby package manager –Create numerical utilities, as well as utilities that process and analyze HTML/XML –Implement purely functional and metaprogramming techniques to save time and effort –Optimize, profile, and test your code to make sure that it not only does its job, but does it well –Create web applications using Rails Ruby is the fastest growing programming language today, and for good reason: its elegant syntax and readable code make for prolific and happy programmers. But it can be difficult to understand and implement without a little help. Ruby by Example shows you how to take advantage of Ruby as you explore Ruby's fundamental concepts in action.
