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

    Fat, they told us, was the enemy. Then it was salt, then sugar, then cholesterol... and on it goes. Americans listened and they lost -- but not their excess fat. What they lost was their health and waistlines. Americans are the fattest people on earth... and why? Mainly because of the food they eat. In this scientific and revolutionary book, based on Nobel Prize-winning research, medical visionary and former Massachusetts Institute of Technology researcher Dr. Barry Sears makes peak physical and mental performance, as well as permanent fat loss, simple for you to understand and achieve. With lists of good and bad carbohydrates, easy-to-follow food blocks and delicious recipes, The Zone provides all you need to begin your journey toward permanent fat loss, great health and all-round peak performance. In balance, your body will not only burn fat, but you'll fight heart disease, diabetes, PMS, chronic fatigue, depression and cancer, as well as alleviate the painful symptoms of diseases such as multiple sclerosis and HIV. This Zone state of exceptional health is well-known to champion athletes. Your own journey toward it can begin with your next meal. You will no longer think of food as merely an item of pleasure or a means to appease hunger. Food is your medicine and your ticket to that state of ultimate body balance, strength and great health: the Zone.

    

    How Buildings Learn is a masterful new synthesis that proposes that buildings adapt best when constantly refined and reshaped by their occupants, and that architects can mature from being artists of space to becoming artists of time. From the connected farmhouses of New England to I.M. Pei's Media Lab, from "satisficing" to "form follows funding," from the evolution of bungalows to the invention of Santa Fe Style, from Low Road military surplus buildings to a High Road English classic like Chatsworth—this is a far-ranging survey of unexplored essential territory.More than any other human artifacts, buildings improve with time—if they're allowed to. How Buildings Learn shows how to work with time rather than against it.

    For courses in Principles of Management, this title takes a traditional, balanced approach to the four functions of management.

    

    Completely revised and updated, this new edition is the most accurate guide to national and international SW, MW, and FM broadcasting available. "The World Radio TV Handbook" is divided into a number of sections covering numerous topics, from National Radio - which looks at the world's domestic radio services, listed by country and including contact details, to International Radio - featuring full facts about all broadcasters transmitting internationally; and from Television Broadcasts - which details the world's main national broadcasters and large regional networks to frequency lists of all MW and international and domestic SW broadcasts. Also included in this revised edition is a reference section that contains listings of international and domestic transmitter sites, standard time and frequency transmissions, DX Club information, as well as other essential print and electronic resources.

    Despite its title, it's not wild ranting pseudo-science to be dismissed by those with brains. Rather, Amdahl maintains that one need not understand quantum physics to grasp how electricity works in practical applications. To understand your toaster or your fax machine, it doesn't really matter whether there are electrons or not, and it's a lot easier and more fun to start with the toaster than with quarks and calculus. The book is mildly weird, often funny, always clear and easy to understand. It assumes the reader doesn't know a volt from a hole in the ground and gently leads him or her through integrated circuits, radio, oscillators and the basics of the digital revolution using examples that include green buffalo, microscopic beer parties, break-dancing chickens and naked Norwegian girls in rowboats. OK, it's more than mildly weird.The book has been reprinted numerous times since 1991 and has achieved minor cult status. Reviewed and praised in dozens of electronics and educational magazines, it is used as a text by major corporations, colleges, high schools, military schools and trade schools. It has been studied by education programs at colleges across the United States. This book was making wise cracks in the corner before anyone thought of designing books for dummies and idiots; some say it helped to inspire that industry.It may be the only "introduction to electronics books" with back cover comments by Dave Barry, Ray Bradbury, Clive Cussler, and George Garrett, as well as recomendations from Robert Hazen, Bob Mostafapour, Dr. Roger Young, Dr. Wayne Green, Scott Rundle, Brian Battles, Michelle Guido, Herb Reichert and Emil Venere. As Monitoring Times said, "Perhaps the best electronics book ever. If you'd like to learn about basic electronics but haven't been able to pull it off, get There Are No Electrons. Just trust us. Get the book."

     The role of the devil's advocate is nearly universal in business today. It allows individuals to step outside themselves and raise questions and concerns that effectively kill new projects and ideas, while claiming no personal responsibility. Nothing is more potent in stifling innovation. Drawing on nearly 20 years of experience managing IDEO, Kelley identifies ten roles people can play in an organization to foster innovation and new ideas while offering an effective counter to naysayers. Among these approaches are the Anthropologist—the person who goes into the field to see how customers use and respond to products, to come up with new innovations; the Cross-pollinator who mixes and matches ideas, people, and technology to create new ideas that can drive growth; and the Hurdler, who instantly looks for ways to overcome the limits and challenges to any situation. Filled with engaging stories of how companies like Kraft, Procter and Gamble, Cargill and Samsung have incorporated IDEO's thinking to transform the customer experience, THE TEN FACES OF INNOVATION is an extraordinary guide to nurturing and sustaining a culture of continuous innovation and renewal.

    Ashlee Vance captures the full spectacle and arc of the genius's life and work, from his tumultuous upbringing in South Africa and flight to the United States to his dramatic technical innovations and entrepreneurial pursuits. Vance uses Musk's story to explore one of the pressing questions of our age: can the nation of inventors and creators who led the modern world for a century still compete in an age of fierce global competition? He argues that Musk is an amalgam of legendary inventors and industrialists including Thomas Edison, Henry Ford, Howard Hughes, and Steve Jobs. More than any other entrepreneur today, Musk has dedicated his energies and his own vast fortune to inventing a future that is as rich and far-reaching as the visionaries of the golden age of science-fiction fantasy

    The PMBOK® Guide – Sixth Edition now contains detailed information about agile; while the Agile Practice Guide, created in partnership with Agile Alliance®, serves as a bridge to connect waterfall and agile. Together they are a powerful tool for project managers.

    It will introduce a new way of looking not only at the treatment of circuits, but also at the treatment of introductory coursework in engineering in general. Using the concept of ''abstraction, '' the book attempts to form a bridge between the world of physics and the world of large computer systems. In particular, it attempts to unify electrical engineering and computer science as the art of creating and exploiting successive abstractions to manage the complexity of building useful electrical systems. Computer systems are simply one type of electrical systems
