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.

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 Higher Order Perl written by Mark Jason Dominus and published by Elsevier. This book was released on 2005-03-31 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most Perl programmers were originally trained as C and Unix programmers, so the Perl programs that they write bear a strong resemblance to C programs. However, Perl incorporates many features that have their roots in other languages such as Lisp. These advanced features are not well understood and are rarely used by most Perl programmers, but they are very powerful. They can automate tasks in everyday programming that are difficult to solve in any other way. One of the most powerful of these techniques is writing functions that manufacture or modify other functions. For example, instead of writing ten similar functions, a programmer can write a general pattern or framework that can then create the functions as needed according to the pattern. For several years Mark Jason Dominus has worked to apply functional programming techniques to Perl. Now Mark brings these flexible programming methods that he has successfully taught in numerous tutorials and training sessions to a wider audience.* Introduces powerful programming methodsnew to most Perl programmersthat were previously the domain of computer scientists* Gradually builds up confidence by describing techniques of progressive sophistication* Shows how to improve everyday programs and includes numerous engaging code examples to illustrate the methods

Download or read book The Four Tendencies written by Gretchen Rubin and published by Harmony. This book was released on 2017-09-12 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: NEW YORK TIMES BESTSELLER • Are you an Upholder, a Questioner, an Obliger, or a Rebel? From the author of Better Than Before and The Happiness Project comes a groundbreaking analysis of personality type that “will immediately improve every area of your life” (Melissa Urban, co-founder of the Whole30). During her multibook investigation into human nature, Gretchen Rubin realized that by asking the seemingly dry question “How do I respond to expectations?” we gain explosive self-knowledge. She discovered that based on their answer, people fit into Four Tendencies: • Upholders meet outer and inner expectations readily. “Discipline is my freedom.” • Questioners meet inner expectations, but meet outer expectations only if they make sense. “If you convince me why, I’ll comply.” • Obligers (the largest Tendency) meet outer expectations, but struggle to meet inner expectations—therefore, they need outer accountability to meet inner expectations. “You can count on me, and I’m counting on you to count on me.” • Rebels (the smallest group) resist all expectations, outer and inner alike. They do what they choose to do, when they choose to do it, and typically they don’t tell themselves what to do. “You can’t make me, and neither can I.” Our Tendency shapes every aspect of our behavior, so using this framework allows us to make better decisions, meet deadlines, suffer less stress, and engage more effectively. It’s far easier to succeed when you know what works for you. With sharp insight, compelling research, and hilarious examples, The Four Tendencies will help you get happier, healthier, more productive, and more creative.
Download or read book Rails 5 Test Prescriptions written by Noel Rappin and published by Pragmatic Bookshelf. This book was released on 2018-02-16 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Does your Rails code suffer from bloat, brittleness, or inaccuracy? Cure these problems with the regular application of test-driven development. You'll use Rails 5.1, Minitest 5, and RSpec 3.6, as well as popular testing libraries such as factory_girl and Cucumber. Updates include Rails 5.1 system tests and Webpack integration. Do what the doctor ordered to make your applications feel all better. Side effects may include better code, fewer bugs, and happier developers. Your Ruby on Rails application is sick. Deadlines are looming, but every time you make the slightest change to the code, something else breaks. Nobody remembers what that tricky piece of code was supposed to do, and nobody can tell what it actually does. Plus, it has bugs. You need test-driven development: a process for improving the design, maintainability, and long-term viability of software. With both practical code examples and discussion of why testing works, this book starts with the most basic features delivered as part of core Ruby on Rails. Once you've integrated those features into your coding practice, work with popular third-party testing tools such as RSpec, Jasmine, Cucumber, and factory_girl. Test the component parts of a Rails application, including the back-end model logic and the front-end display logic. With Rails examples, use testing to enable your code to respond better to future change. Plus, see how to handle real-world testing situations. This new edition has been updated to Rails 5.1 and RSpec 3.6 and contains full coverage of new Rails features, including system tests and the Webpack-based JavaScript setup. What You Need: Ruby 2.4, Rails 5.1
