    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

    The 20 stand-alone chapters of this new work describe how technological failures result from the incompatibilities between the way things are designed and the way people actually perceive, think, and act. New technologies will succeed or fail based on our ability to minimize these incompatibilities between the characteristics of people and the characteristics of the things we create and use.This book is the quintessential 'must read' for all those who deal with technology in any fashion. From the frustration of an awkward ATM machine to the threat of accidental, nuclear Armageddon, Casey shows how the same crucial factors come into play told through the very eyes of those people who saw and experienced these things. No student of design, psychology, behavioral science, or technology should be without this book, and neither should any intelligent member of society who wants to know what goes on with the successes and failures of modern technology.Sit ringside to the action where compelling events unfold. The stories in this book will take you to airports and airline cabins, an amusement park, a fertility clinic, a pharmaceutical plant, an emergency dispatch center, the Olympic games, and a bank; to hospitals, spacecraft, ships, and cars. From the coasts of Peru and Monterey, in orbit aboard the International Space Station, the freeways of Southern California and the back roads of France, the battlefields of Afghanistan, and a nuclear fuel plant in Japan this is The Atomic Chef.

    Cases, examples and problems from a variety of project types are used to illustrate the text.

    Gordon strips engineering of its confusing technical terms, communicating its founding principles in accessible, witty prose.For anyone who has ever wondered why suspension bridges don't collapse under eight lanes of traffic, how dams hold back--or give way under--thousands of gallons of water, or what principles guide the design of a skyscraper, a bias-cut dress, or a kangaroo, this book will ease your anxiety and answer your questions.Structures: Or Why Things Don't Fall Down is an informal explanation of the basic forces that hold together the ordinary and essential things of this world--from buildings and bodies to flying aircraft and eggshells. In a style that combines wit, a masterful command of his subject, and an encyclopedic range of reference, Gordon includes such chapters as "How to Design a Worm" and "The Advantage of Being a Beam," offering humorous insights in human and natural creation.Architects and engineers will appreciate the clear and cogent explanations of the concepts of stress, shear, torsion, fracture, and compression. If you're building a house, a sailboat, or a catapult, here is a handy tool for understanding the mechanics of joinery, floors, ceilings, hulls, masts--or flying buttresses.Without jargon or oversimplification, Structures opens up the marvels of technology to anyone interested in the foundations of our everyday lives.

    Through the worst years of the Great Depression as many as five thousand laborers toiled twenty-four hours a day, seven days a week, to erect the huge structure that would harness the Colorado River and transform the American West.Construction of the giant dam was a triumph of human ingenuity, yet the full story of this monumental endeavor has never been told. Now, in an engrossing, fast-paced narrative, Joseph E. Stevens recounts the gripping saga of Hoover Dam. Drawing on a wealth of material, including manuscript collections, government documents, contemporary newspaper and magazine accounts, and personal interviews and correspondence with men and women who were involved with the construction, he brings the Hoover Dam adventure to life.Described here in dramatic detail are the deadly hazards the work crews faced as they hacked and blasted the dam’s foundation out of solid rock; the bitter political battles and violent labor unrest that threatened to shut the job down; the deprivation and grinding hardship endured by the workers’ families; the dam builders’ gambling, drinking, and whoring sprees in nearby Las Vegas; and the stirring triumphs and searing moments of terror as the massive concrete wedge rose inexorably from the canyon floor.Here, too, is an unforgettable cast of characters: Henry Kaiser, Warren Bechtel, and Harry Morrison, the ambitious, headstrong construction executives who gambled fortune and fame on the Hoover Dam contract; Frank Crowe, the brilliant, obsessed field engineer who relentlessly drove the work force to finish the dam two and a half years ahead of schedule; Sims Ely, the irascible, teetotaling eccentric who ruled Boulder City, the straightlaced company town created for the dam workers by the federal government; and many more men and women whose courage and sacrifice, greed and frailty, made the dam’s construction a great human, as well as technological, adventure.Hoover Dam is a compelling, irresistible account of an extraordinary American epic.

    In the process, they have remade the fabric of the world into newly functional objects that are also works of art to be admired. In this second edition of his popular Existential Pleasures of Engineering, Samuel Florman explores how engineers think and feel about their profession.A deeply insightful and refreshingly unique text, this book corrects the myth that engineering is cold and passionless. Indeed, Florman celebrates engineering not only crucial and fundamental but also vital and alive; he views it as a response to some of our deepest impulses, an endeavor rich in spiritual and sensual rewards. Opposing the "anti-technology" stance, Florman gives readers a practical, creative, and even amusing philosophy of engineering that boasts of pride in his craft.

    He is ultra competitive but never forgets to have fun. An immensely likeable man.' Damon HillThe world’s foremost designer in Formula One, Adrian Newey OBE is arguably one of Britain’s greatest engineers and this is his fascinating, powerful memoir.How to Build a Car explores the story of Adrian’s unrivalled 35-year career in Formula One through the prism of the cars he has designed, the drivers he has worked alongside and the races in which he’s been involved.A true engineering genius, even in adolescence Adrian’s thoughts naturally emerged in shape and form – he began sketching his own car designs at the age of 12 and took a welding course in his school summer holidays. From his early career in IndyCar racing and on to his unparalleled success in Formula One, we learn in comprehensive, engaging and highly entertaining detail how a car actually works. Adrian has designed for the likes of Mario Andretti, Nigel Mansell, Alain Prost, Damon Hill, David Coulthard, Mika Hakkinen, Mark Webber and Sebastian Vettel, always with a shark-like purity of purpose: to make the car go faster. And while his career has been marked by unbelievable triumphs, there have also been deep tragedies; most notably Ayrton Senna’s death during his time at Williams in 1994.Beautifully illustrated with never-before-seen drawings, How to Build a Car encapsulates, through Adrian’s remarkable life story, precisely what makes Formula One so thrilling – its potential for the total synchronicity of man and machine, the perfect combination of style, efficiency and speed.

    Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.
