It teaches Clojure from the basics to advanced topics using practical, real-world application examples. Blow through the theory and dive into practical matters like unit-testing and environment set-up, all the way through building a scalable web-application using domain-specific languages, Hadoop, HBase, and RabbitMQ. About the TechnologyClojure is a modern Lisp for the JVM, and it has the strengths you'd expect: first-class functions, macros, support for functional programming, and a Lisp-like, clean programming style. About this BookClojure in Action is a practical guide focused on applying Clojure to practical programming challenges. You'll start with a language tutorial written for readers who already know OOP. Then, you'll dive into the use cases where Clojure really shines: state management, safe concurrency and multicore programming, first-class code generation, and Java interop. In each chapter, you'll first explore the unique characteristics of a problem area and then discover how to tackle them using Clojure. Along the way, you'll explore practical matters like architecture, unit testing, and set-up as you build a scalable web application that includes custom DSLs, Hadoop, HBase, and RabbitMQ.

    In Taiwan, a spate of deaths at gaming cafés is raising a question: why is it that some of us are playing games beyond the limits of our physical wellbeing?Death by Video Game uncovers the real stories behind our video game obsession. Along the way, award-winning journalist Simon Parkin meets the players and game developers at the frontline of virtual extremism, including the New York surgeon attempting to break the Donkey Kong world record; the Minecraft player three years into an epic journey towards the edge of the game's vast virtual world and the German hacker who risked prison to discover the secrets behind Half-Life 2.Investigating the impact of video games on our lives, Death by Video Game will change the way we think about our virtual playgrounds.

    Apparently, they are the unequivocal source of many societal ills. But what does science actually have to say about the effects that playing them can have on us?In Lost in a Good Game, psychologist Pete Echells takes us on a journey through that scientific data and research, as well as his own past experiences with video games, which helped him cope in the aftermath of a tragedy.His story reveals that, really, our worries are unfounded - and that in playing, studying and living through them we can understand what it means to be human.

    If its purpose is to entertain or to provoke thought, it makes readers want to come back for more.Revised and updated, this guide covers four essential aspects of good writing:Individual words - spelling variations, hyphenation, frequently confused homonyms, frequently misused words and phrases, irregular plurals and negatives, and uses of capitalization and type style to add special meaningsPunctuation - the role of each mark in achieving clarity and affecting tone, and demonstration of how misuses can lead to ambiguitySyntax and structure - agreement of subject and verb, parallel construction, modifiers, tenses, pronouns, active versus passive voice, and moreStyle - advice on the less hard-and-fast areas of clarity and tone, including sentence length and order, conciseness, simplification, reading level, jargon and cliches, and subtletyFilled with self-test exercises and whimsical literary quotations, "Grammatically Correct" steers clear of academic stuffiness, focusing instead on practical strategies and intuitive explanations.Discussions are designed to get to the heart of a concept and provide a sufficient sense of when and how to use it, along with examples that show what ambiguities or misinterpretations might result if the rules are not followed. In cases where there is more than one acceptable way to do something, the approach is not to prescribe one over another but simply to describe the options.Readers of this book will never break the rules of language again - unintentionally."

    With all our media now traveling a single network, an unprecedented potential is building for centralized control over what Americans see and hear. Could history repeat itself with the next industrial consolidation? Could the Internet—the entire flow of American information—come to be ruled by one corporate leviathan in possession of “the master switch”? That is the big question of Tim Wu’s pathbreaking book.As Wu’s sweeping history shows, each of the new media of the twentieth century—radio, telephone, television, and film—was born free and open. Each invited unrestricted use and enterprising experiment until some would-be mogul battled his way to total domination. Here are stories of an uncommon will to power, the power over information: Adolph Zukor, who took a technology once used as commonly as YouTube is today and made it the exclusive prerogative of a kingdom called Hollywood . . . NBC’s founder, David Sarnoff, who, to save his broadcast empire from disruptive visionaries, bullied one inventor (of electronic television) into alcoholic despair and another (this one of FM radio, and his boyhood friend) into suicide . . . And foremost, Theodore Vail, founder of the Bell System, the greatest information empire of all time, and a capitalist whose faith in Soviet-style central planning set the course of every information industry thereafter.Explaining how invention begets industry and industry begets empire—a progress often blessed by government, typically with stifling consequences for free expression and technical innovation alike—Wu identifies a time-honored pattern in the maneuvers of today’s great information powers: Apple, Google, and an eerily resurgent AT&T. A battle royal looms for the Internet’s future, and with almost every aspect of our lives now dependent on that network, this is one war we dare not tune out.Part industrial exposé, part meditation on what freedom requires in the information age, The Master Switch is a stirring illumination of a drama that has played out over decades in the shadows of our national life and now culminates with terrifying implications for our future.

    In this comprehensive and readable book--already a classic statement of the aesthetics of digital media, acclaimed by practitioners and theorists alike--Janet Murray shows how the computer is reshaping the stories we live by. Murray discusses the unique properties and pleasures of digital environments and connects them with the traditional satisfactions of narrative. She analyzes the dramatic satisfaction of participatory stories and considers what would be necessary to move interactive fiction from the formats of childish games and confusing labyrinths into a mature and compelling art form. Through a blend of imagination and techno-wizardry, Murray provides both readers and writers with a guide to the storytelling of the future.

    So what, then, is play? In Play Matters, Miguel Sicart argues that to play is to be in the world; playing is a form of understanding what surrounds us and a way of engaging with others. Play goes beyond games; it is a mode of being human.We play games, but we also play with toys, on playgrounds, with technologies and design. Sicart proposes a theory of play that doesn't derive from a particular object or activity but is a portable tool for being—not tied to objects but brought by people to the complex interactions that form their daily lives. It is not separated from reality; it is part of it. It is pleasurable, but not necessarily fun. Play can be dangerous, addictive, and destructive.Along the way, Sicart considers playfulness, the capacity to use play outside the context of play; toys, the materialization of play--instruments but also play pals; playgrounds, play spaces that enable all kinds of play; beauty, the aesthetics of play through action; political play--from Maradona's goal against England in the 1986 World Cup to the hactivist activities of Anonymous; the political, aesthetic, and moral activity of game design; and why play and computers get along so well.

    Fueled by unprecedented advances in technology, boundless imaginations, and an insatiable addiction to fantastic new worlds of play, the video game has gone supernova, rocketing two generations of fans into an ever-expanding universe where art, culture, reality, and emotion collide. As a testament to the cultural impact of the game industry’s mega morph, the Smithsonian American Art Museum, with curator and author Chris Melissinos, conceived the forthcoming exhibition, The Art of Video Games, which will run from March 16 to September 30, 2012.* Welcome Books will release the companion book this March. Melissinos presents video games as not just mere play, but richly textured emotional and social experiences that have crossed the boundary into culture and art.Along with a team of game developers, designers, and journalists, Melissinos chose a pool of 240 games across five different eras to represent the diversity of the game world. Criteria included visual effects, creative use of technologies, and how world events and popular culture manifested in the games. The museum then invited the public to go online to help choose the games. More than 3.7 million votes (from 175 countries) later, the eighty winners featured in The Art of Video Games exhibition and book were selected.From the Space Invaders of the seventies to sophisticated contemporary epics BioShock and Uncharted 2, Melissinos examines each of the winning games, providing a behind-the-scenes look at their development and innovation, and commentary on the relevance of each in the history of video games. Over 100 composite images, created by Patrick O’Rourke, and drawn directly from the games themselves, illustrate the evolution of video games as an artistic medium, both technologically and creatively. Additionally, The Art of Video Games includes fascinating interviews with influential artists and designers–from pioneers such as Nolan Bushnell to contemporary innovators including Warren Spector, Tim Schafer and Robin Hunicke. The foreword was written by Elizabeth Broun, director of the Smithsonian American Art Museum and Mike Mika, noted game preservationist and prolific developer, contributed the introduction the introduction. *After Washington D.C., the exhibition travels to several cities across the United States, including Boca Raton (Museum of Art), Seattle (EMP Museum), Yonkers, NY (Hudson River Museum) and Flint, MI (Flint Institute of Arts).

    In arcades, living rooms, student dorms, and (admit it) offices from Ohio to Osaka, video games have become a fixture in people's lives, marking a tectonic shift in the entertainment landscape.Now, as Hollywood and Silicon Valley rush to sell us online interactive multimedia everything, J. C. Herz brings us the first popular history and critique of the video-game phenomenon. From the Cold War computer programmers who invented the first games (when they should have been working) to the studios where the networked 3-D theme parks of the future are created, Herz brings to life the secret history of Space Invaders, Pac Man, Super Mario, Myst, Doom, and other celebrated games. She explains why different kinds of games have taken hold (and what they say about the people who play them) and what we can expect from a generation that has logged millions of hours vanquishing digital demons.Written with 64-bit energy and filled with Herz's sharp-edged insights and asides, Joystick Nation is a fascinating pop culture odyssey that's must-reading for media junkies, pop historians, and anyone who pines for their old Atari.
