Based on original material and previously unavailable documents, this acclaimed book is the definitive biography of the man considered by many to be the founding father of modern electrical technology. Among Tesla's creations were the channeling of alternating current, fluorescent and neon lighting, wireless telegraphy, and the giant turbines that harnessed the power of Niagara Falls.

    Journalist Geoff Keighley was granted unprecedented “fly on the wall” access to Valve over the past three years to create this story. From the hush-hush Portal prequel that was shelved to the last minute scramble to complete the game’s story, The Final Hours of Portal 2 is a gripping and dramatic story. Please note the Kindle version does not include as many photos or the videos that are available in the iPad version.

    In this book, Agile Alliance cofounder Mike Cohn discusses the philosophy of agile estimating and planning and shows you exactly how to get the job done, with real-world examples and case studies.Concepts are clearly illustrated and readers are guided, step by step, toward how to answer the following questions: What will we build? How big will it be? When must it be done? How much can I really complete by then? You will first learn what makes a good plan-and then what makes it agile.Using the techniques in Agile Estimating and Planning , you can stay agile from start to finish, saving time, conserving resources, and accomplishing more. Highlights include:Why conventional prescriptive planning fails and why agile planning works How to estimate feature size using story points and ideal days--and when to use each How and when to re-estimate How to prioritize features using both financial and nonfinancial approaches How to split large features into smaller, more manageable ones How to plan iterations and predict your team's initial rate of progress How to schedule projects that have unusually high uncertainty or schedule-related risk How to estimate projects that will be worked on by multiple teams Agile Estimating and Planning supports any agile, semiagile, or iterative process, including Scrum, XP, Feature-Driven Development, Crystal, Adaptive Software Development, DSDM, Unified Process, and many more. It will be an indispensable resource for every development manager, team leader, and team member.

    In 1997, she wroteClose to the Machine, the now classic and still definitive account of life as a coder at the birth of what would be a sweeping technological, cultural, and financial revolution.The intervening twenty years has seen, among other things, the rise of the Internet, the ubiquity of once unimaginably powerful computers, and the thorough transformation of our economy and society—as Ullman’s clique of socially awkward West Coast geeks became our new elite, elevated for and insulated by a technical mastery that few could achieve.In Life in Code, Ullman presents a series of essays that unlock and explain—and don’t necessarily celebrate—how we got to now, as only she can, with a fluency and expertise that’s unusual in someone with her humanistic worldview, and with the sharp insight and brilliant prose that are uniquely her own. Life in Code is an essential text toward our understanding of the last twenty years—and the next twenty.

    Like other immigrant groups before them, they showed up with little money but with an intense work ethic and an unshakeable belief in the promise of the United States. Many of them lived in a world outside the law, working in a shadow economy overseen by the ruthless gangs that ruled the narrow streets of New York’s Chinatown.The figure who came to dominate this Chinese underworld was a middle-aged grandmother known as Sister Ping. Her path to the American dream began with an unusual business run out of a tiny noodle store on Hester Street. From her perch above the shop, Sister Ping ran a full-service underground bank for illegal Chinese immigrants. But her real business-a business that earned an estimated $40 million-was smuggling people. As a “snakehead,” she built a complex—and often vicious—global conglomerate, relying heavily on familial ties, and employing one of Chinatown's most violent gangs to protect her power and profits. Like an underworld CEO, Sister Ping created an intricate smuggling network that stretched from Fujian Province to Hong Kong to Burma to Thailand to Kenya to Guatemala to Mexico. Her ingenuity and drive were awe-inspiring both to the Chinatown community—where she was revered as a homegrown Don Corleone—and to the law enforcement officials who could never quite catch her. Indeed, Sister Ping’s empire only came to light in 1993 when the Golden Venture, a ship loaded with 300 undocumented immigrants, ran aground off a Queens beach. It took New York’s fabled “Jade Squad” and the FBI nearly ten years to untangle the criminal network and home in on its unusual mastermind.THE SNAKEHEAD is a panoramic tale of international intrigue and a dramatic portrait of the underground economy in which America’s twelve million illegal immigrants live. Based on hundreds of interviews, Patrick Radden Keefe’s sweeping narrative tells the story not only of Sister Ping, but of the gangland gunslingers who worked for her, the immigration and law enforcement officials who pursued her, and the generation of penniless immigrants who risked death and braved a 17,000 mile odyssey so that they could realize their own version of the American dream. The Snakehead offers an intimate tour of life on the mean streets of Chinatown, a vivid blueprint of organized crime in an age of globalization and a masterful exploration of the ways in which illegal immigration affects us all.www.doubleday.com

    In the 1987 Nintendo Entertainment System videogame Zelda II: The Adventure of Link, a character famously declared: I AM ERROR. Puzzled players assumed that this cryptic mesage was a programming flaw, but it was actually a clumsy Japanese-English translation of "My Name is Error," a benign programmer's joke. In I AM ERROR Nathan Altice explores the complex material histories of the Nintendo Entertainment System (and its Japanese predecessor, the Family Computer), offering a detailed analysis of its programming and engineering, its expressive affordances, and its cultural significance.Nintendo games were rife with mistranslated texts, but, as Altice explains, Nintendo's translation challenges were not just linguistic but also material, with consequences beyond simple misinterpretation. Emphasizing the technical and material evolution of Nintendo's first cartridge-based platform, Altice describes the development of the Family Computer (or Famicom) and its computational architecture; the "translation" problems faced while adapting the Famicom for the U.S. videogame market as the redesigned Entertainment System; Nintendo's breakthrough console title Super Mario Bros. and its remarkable software innovations; the introduction of Nintendo's short-lived proprietary disk format and the design repercussions on The Legend of Zelda; Nintendo's efforts to extend their console's lifespan through cartridge augmentations; the Famicom's Audio Processing Unit (APU) and its importance for the chiptunes genre; and the emergence of software emulators and the new kinds of play they enabled.

    In this one-of-a-kind text, author V. Anton Spraul breaks down the ways that programmers solve problems and teaches you what other introductory books often ignore: how to Think Like a Programmer. Each chapter tackles a single programming concept, like classes, pointers, and recursion, and open-ended exercises throughout challenge you to apply your knowledge. You'll also learn how to:Split problems into discrete components to make them easier to solve Make the most of code reuse with functions, classes, and libraries Pick the perfect data structure for a particular job Master more advanced programming tools like recursion and dynamic memory Organize your thoughts and develop strategies to tackle particular types of problems Although the book's examples are written in C++, the creative problem-solving concepts they illustrate go beyond any particular language; in fact, they often reach outside the realm of computer science. As the most skillful programmers know, writing great code is a creative art—and the first step in creating your masterpiece is learning to Think Like a Programmer.
