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 Advanced Rails written by Brad Ediger and published by "O'Reilly Media, Inc.". This book was released on 2007-12-21 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ready to go to the next level with Rails? From examining the parts of Ruby that make this framework possible to deploying large Rails applications, Advanced Rails offers you an in-depth look at techniques for dealing with databases, security, performance, web services and much more. Chapters in this book help you understand not only the tricks and techniques used within the Rails framework itself, but also how to make use of ideas borrowed from other programming paradigms. Advanced Rails pays particular attention to building applications that scale -- whether "scale" means handling more users, or working with a bigger and more complex database. You'll find plenty of examples and code samples that explain: Aspects of Ruby that are often confusing or misunderstood Metaprogramming How to develop Rails plug-ins Different database management systems Advanced database features, including triggers, rules, and stored procedures How to connect to multiple databases When to use the Active Support library for generic, reusable functions Security principles for web application design, and security issues endemic to the Web When and when not to optimize performance Why version control and issue tracking systems are essential to any large or long-lived Rails project Advanced Rails also gives you a look at REST for developing web services, ways to incorporate and extend Rails, how to use internationalization, and many other topics. If you're just starting out with rails, or merely experimenting with the framework, this book is not for you. But if you want to improve your skills with Rails through advanced techniques, this book is essential.
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.

Book excerpt: From the author of The Italian Teacher, this acclaimed debut novel set in Rome follows the topsy-turvy lives of the denizens of an English language newspaper. NAMED ONE OF THE BEST BOOKS OF THE YEAR BY Janet Maslin, The New York Times • The Economist • NPR • Slate • The Christian Science Monitor • Financial Times • The Plain Dealer • Minneapolis Star Tribune • St. Louis Post-Dispatch • The Kansas City Star • The Globe and Mail • Publishers Weekly Look in the back of the book for a conversation between Tom Rachman and Malcolm Gladwell Fifty years and many changes have ensued since the paper was founded by an enigmatic millionaire, and now, amid the stained carpeting and dingy office furniture, the staff’s personal dramas seem far more important than the daily headlines. Kathleen, the imperious editor in chief, is smarting from a betrayal in her open marriage; Arthur, the lazy obituary writer, is transformed by a personal tragedy; Abby, the embattled financial officer, discovers that her job cuts and her love life are intertwined in a most unexpected way. Out in the field, a veteran Paris freelancer goes to desperate lengths for his next byline, while the new Cairo stringer is mercilessly manipulated by an outrageous war correspondent with an outsize ego. And in the shadows is the isolated young publisher who pays more attention to his prized basset hound, Schopenhauer, than to the fate of his family’s quirky newspaper. As the era of print news gives way to the Internet age and this imperfect crew stumbles toward an uncertain future, the paper’s rich history is revealed, including the surprising truth about its founder’s intentions. Spirited, moving, and highly original, The Imperfectionists will establish Tom Rachman as one of our most perceptive, assured literary talents.

Book excerpt: “A necessary book for anyone truly interested in what we take from the sea to eat, and how, and why.” —Sam Sifton, The New York Times Book Review Acclaimed author of American Catch and The Omega Princple and life-long fisherman, Paul Greenberg takes us on a journey, examining the four fish that dominate our menus: salmon, sea bass, cod, and tuna. Investigating the forces that get fish to our dinner tables, Greenberg reveals our damaged relationship with the ocean and its inhabitants. Just three decades ago, nearly everything we ate from the sea was wild. Today, rampant overfishing and an unprecedented biotech revolution have brought us to a point where wild and farmed fish occupy equal parts of a complex marketplace. Four Fish offers a way for us to move toward a future in which healthy and sustainable seafood is the rule rather than the exception.
