    Yet inhabitants of virtual worlds rarely achieve this liberty, game researcher Nick Yee contends. Though online games evoke freedom and escapism, Yee shows that virtual spaces perpetuate social norms and stereotypes from the offline world, transform play into labor, and inspire racial scapegoating and superstitious thinking. And the change that does occur is often out of our control and effected by unparalleled—but rarely recognized—tools for controlling what players think and how they behave. Using player surveys, psychological experiments, and in-game data, Yee breaks down misconceptions about who plays fantasy games and the extent to which the online and offline worlds operate separately. With a wealth of entertaining and provocative examples, he explains what virtual worlds are about and why they matter, not only for entertainment but also for business and education. He uses gaming as a lens through which to examine the pressing question of what it means to be human in a digital world. His thought-provoking book is an invitation to think more deeply about virtual worlds and what they reveal to us about ourselves.

    Designers of digital technology products no longer regard their job as designing a physical object--beautiful or utilitarian--but as designing our interactions with it. In Designing Interactions, award-winning designer Bill Moggridge introduces us to forty influential designers who have shaped our interaction with technology. Moggridge, designer of the first laptop computer (the GRiD Compass, 1981) and a founder of the design firm IDEO, tells us these stories from an industry insider's viewpoint, tracing the evolution of ideas from inspiration to outcome. The innovators he interviews--including Will Wright, creator of The Sims, Larry Page and Sergey Brin, the founders of Google, and Doug Engelbart, Bill Atkinson, and others involved in the invention and development of the mouse and the desktop--have been instrumental in making a difference in the design of interactions. Their stories chart the history of entrepreneurial design development for technology.Moggridge and his interviewees discuss such questions as why a personal computer has a window in a desktop, what made Palm's handheld organizers so successful, what turns a game into a hobby, why Google is the search engine of choice, and why 30 million people in Japan choose the i-mode service for their cell phones. And Moggridge tells the story of his own design process and explains the focus on people and prototypes that has been successful at IDEO--how the needs and desires of people can inspire innovative designs and how prototyping methods are evolving for the design of digital technology.Designing Interactions is illustrated with more than 700 images, with color throughout. Accompanying the book is a DVD that contains segments from all the interviews intercut with examples of the interactions under discussion.Interviews with: Bill Atkinson - Durrell Bishop - Brendan Boyle - Dennis Boyle - Paul Bradley - Duane Bray - Sergey Brin - Stu Card - Gillian Crampton Smith - Chris Downs- Tony Dunne - John Ellenby - Doug Englebart - Jane Fulton Suri - Bill Gaver - Bing Gordon - Rob Haitani - Jeff Hawkins - Matt Hunter - Hiroshi Ishii - Bert Keely - David Kelley - Rikako Kojima - Brenda Laurel - David Liddle - Lavrans L?vlie - John Maeda - Paul Mercer - Tim Mott - Joy Mountford - Takeshi Natsuno - Larry Page - Mark Podlaseck - Fiona Raby - Cordell Ratzlaff - Ben Reason - Jun Rekimoto - Steve Rogers - Fran Samalionis - Larry Tesler - Bill Verplank - Terry Winograd - Will Wright

    Do you have an idea for a board game, card game, role-playing game or tabletop game? Have you ever wondered how to get it published? For many years Brian Tinsman reviewed new game submissions for Hasbro, the largest game company in the US.

    Stern administrators lorded over sterile university laboratories and stressed one point to the wide-eyed students privileged enough to set foot within them: Computers were not toys.Defying authority, hackers seized control of monolithic mainframes to create a new breed of computer game: the roguelike, cryptic and tough-as-nails adventures drawn from text-based symbols instead of state-of-the-art 3D graphics.Despite their visual simplicity, roguelike games captivate thousands of players around the world. From the author of the bestselling Stay Awhile and Listen series, Dungeon Hacks introduces you to the visionaries behind some of the most popular roguelikes of all time, and shows how their creations paved the way for the blockbuster video games of today—and beyond.

    It is important that these implementations are the same throughout the Web, otherwise it becomes a messy proprietary place, and lacks consistency. These standards also allow content to be more compatible with multiple different viewing devices, such as screen readers for people with vision impairments, cell phones, PDFs, etc. HTML, XML, and CSS are all such technologies.This book is your essential guide to understanding the advantages you can bring to your web pages by implementing web standards and precisely how to apply them.Web standards such as XHTML and CSS are now fairly well-known technologies, and they will likely be familiar to you, the web designerindeed, they are all around you on the Web. However, within web standards still lies a challengewhile the browser's support for web standards is steadily increasing, many web developers and designers have yet to discover the real benefits of web standards and respect the need to adhere to them. The real art is in truly understanding the benefits and implementing the standards efficiently.As a simple example of its power, you can use CSS to lay out your pages instead of nesting tables. This can make file sizes smaller, allowing pages to load faster, ultimately increasing accessibility for all browsers, devices, and web users. Use XHTML elements correctly so that your markup is compact and more easily understood. Use CSS to style different elements of a web page. Lay out pages easily and effectively. Compare multiple methods of achieving the same results to make better design choices. Learn about advanced web design techniques and their important caveats.Web Standards Solutions is broken down into 16 short chapters, each covering the theory and practice of different web standards concept and showing multiple solutions to given problems for easy learning. You'll learn about multi-column layouts, using image replacement techniques to your best advantage, making the best use of tables and lists, and many more. This highly modular approach allows you to rapidly digest, understand, and utilize the essentials of web standards."

    They think that UI design is like graphic design--the mysterious process by which creative, latte-drinking, all-black-wearing people produce cool-looking, artistic pieces. Most programmers see themselves as analytic, logical thinkers instead--strong at reasoning, weak on artistic judgment, and incapable of doing UI design.In this brilliantly readable book, author Joel Spolsky proposes simple, logical rules that can be applied without any artistic talent to improve any user interface, from traditional GUI applications to websites to consumer electronics. Spolsky's primary axiom, the importance of bringing the program model in line with the user model, is both rational and simple.In a fun and entertaining way, Spolky makesuser interfacedesign easy for programmers to grasp. After reading User Interface Design for Programmers, you'll know how to design interfaces with the user in mind. You'll learn the important principles that underlie all good UI design, and you'll learn how to perform usability testing that works."

    The story of information begins in a time profoundly unlike our own, when every thought and utterance vanishes as soon as it is born. From the invention of scripts and alphabets to the long-misunderstood talking drums of Africa, Gleick tells the story of information technologies that changed the very nature of human consciousness. He provides portraits of the key figures contributing to the inexorable development of our modern understanding of information: Charles Babbage, the idiosyncratic inventor of the first great mechanical computer; Ada Byron, the brilliant and doomed daughter of the poet, who became the first true programmer; pivotal figures like Samuel Morse and Alan Turing; and Claude Shannon, the creator of information theory itself. And then the information age arrives. Citizens of this world become experts willy-nilly: aficionados of bits and bytes. And we sometimes feel we are drowning, swept by a deluge of signs and signals, news and images, blogs and tweets. The Information is the story of how we got here and where we are heading.

    Plenty of books describe what agile development is or why it helps software projects succeed, but very few combine information for developers, managers, testers, and customers into a single package that they can apply directly. This book provides no-nonsense advice on agile planning, development, delivery, and management taken from the authors' many years of experience with Extreme Programming (XP). You get a gestalt view of the agile development process, including comprehensive guidance for non-technical readers and hands-on technical practices for developers and testers. The Art of Agile Development gives you clear answers to questions such as:How can we adopt agile development? Do we really need to pair program? What metrics should we report? What if I can't get my customer to participate? How much documentation should we write? When do we design and architect? As a non-developer, how should I work with my agile team? Where is my product roadmap? How does QA fit in? The book teaches you how to adopt XP practices, describes each practice in detail, then discusses principles that will allow you to modify XP and create your own agile method. In particular, this book tackles the difficult aspects of agile development: the need for cooperation and trust among team members. Whether you're currently part of an agile team, working with an agile team, or interested in agile development, this book provides the practical tips you need to start practicing agile development. As your experience grows, the book will grow with you, providing exercises and information that will teach you first to understand the rules of agile development, break them, and ultimately abandon rules altogether as you master the art of agile development. "Jim Shore and Shane Warden expertly explain the practices and benefits of Extreme Programming. They offer advice from their real-world experiences in leading teams. They answer questions about the practices and show contraindications - ways that a practice may be mis-applied. They offer alternatives you can try if there are impediments to applying a practice, such as the lack of an on-site customer. --Ken Pugh, Author of Jolt Award Winner, Prefactoring "I will leave a copy of this book with every team I visit." --Brian Marick, Exampler Consulting
