Siracusa's overview, wrap-up, and critique of everything new in OS X 10.10 Yosemite.

    Today, Rails developers and architects need better ways to interface with legacy systems, move into the cloud, and scale to handle higher volumes and greater complexity. In Service-Oriented Design with Ruby and Rails Paul Dix introduces a powerful, services-based design approach geared toward overcoming all these challenges. Using Dix's techniques, readers can leverage the full benefits of both Ruby and Rails, while overcoming the difficulties of working with larger codebases and teams. Dix demonstrates how to integrate multiple components within an enterprise application stack; create services that can easily grow and connect; and design systems that are easier to maintain and upgrade. Key concepts are explained with detailed Ruby code built using open source libraries such as ActiveRecord, Sinatra, Nokogiri, and Typhoeus. The book concludes with coverage of security, scaling, messaging, and interfacing with third-party services. Service-Oriented Design with Ruby and Rails will help you Build highly scalable, Ruby-based service architectures that operate smoothly in the cloud or with legacy systems Scale Rails systems to handle more requests, larger development teams, and more complex code bases Master new best practices for designing and creating services in Ruby Use Ruby to glue together services written in any language Use Ruby libraries to build and consume RESTful Web services Use Ruby JSON parsers to quickly represent resources from HTTP services Write lightweight, well-designed API wrappers around internal or external services Discover powerful non-Rails frameworks that simplify Ruby service implementation Implement standards-based enterprise messaging with Advanced Message Queuing Protocol (AMQP) Optimize performance with load balancing and caching Provide for security and authentication

    D&D captured the attention of a small but influential group of players, many of whom also gravitated to the computer networks that were then appearing on college campuses around the globe. With the subsequent emergence of the personal computer, a generation of geeky storytellers arose that translated communal D&D playing experiences into the virtual world of computer games. The result of that 40-year journey is today's massive global community of players who, through games, have forged very real friendships and built thriving lives in virtual worlds. Dungeons & Dreamers follows the designers, developers, and players who built the virtual games and communities that define today's digital entertainment landscape and explores the nature of what it means to live and thrive in virtual communities.

    People of all ages and from all walks of life now spend thousands of hours—and dollars—partaking in this popular new brand of escapism. But the line between fantasy and reality is starting to blur. Players have created virtual societies with governments and economies of their own whose currencies now trade against the dollar on eBay at rates higher than the yen. And the players who inhabit these synthetic worlds are starting to spend more time online than at their day jobs. In Synthetic Worlds, Edward Castronova offers the first comprehensive look at the online game industry, exploring its implications for business and culture alike. He starts with the players, giving us a revealing look into the everyday lives of the gamers—outlining what they do in their synthetic worlds and why. He then describes the economies inside these worlds to show how they might dramatically affect real world financial systems, from potential disruptions of markets to new business horizons. Ultimately, he explores the long-term social consequences of online games: If players can inhabit worlds that are more alluring and gratifying than reality, then how can the real world ever compete? Will a day ever come when we spend more time in these synthetic worlds than in our own? Or even more startling, will a day ever come when such questions no longer sound alarmist but instead seem obsolete? With more than ten million active players worldwide—and with Microsoft and Sony pouring hundreds of millions of dollars into video game development—online games have become too big to ignore. Synthetic Worlds spearheads our efforts to come to terms with this virtual reality and its concrete effects. “Illuminating. . . . Castronova’s analysis of the economics of fun is intriguing. Virtual-world economies are designed to make the resulting game interesting and enjoyable for their inhabitants. Many games follow a rags-to-riches storyline, for example. But how can all the players end up in the top 10%? Simple: the upwardly mobile human players need only be a subset of the world's population. An underclass of computer-controlled 'bot' citizens, meanwhile, stays poor forever. Mr. Castronova explains all this with clarity, wit, and a merciful lack of academic jargon.”—The Economist “Synthetic Worlds is a surprisingly profound book about the social, political, and economic issues arising from the emergence of vast multiplayer games on the Internet. What Castronova has realized is that these games, where players contribute considerable labor in exchange for things they value, are not merely like real economies, they are real economies, displaying inflation, fraud, Chinese sweatshops, and some surprising in-game innovations.”—Tim Harford, Chronicle of Higher Education

    James Paul Gee begins his new book with 'I want to talk about vide games- yes, even violent video games - and say some positive things about them'. With this simple but explosive beginning, one of America's most well-respected professors of education looks seriously at the good that can come from playing video games. Gee is interested in the cognitive development that can occur when someone is trying to escape a maze, find a hidden treasure and, even, blasting away an enemy with a high-powered rifle. Talking about his own video-gaming experience learning and using games as diverse as Lara Croft and Arcanum, Gee looks at major specific cognitive activities: How individuals develop a sense of identity; How one grasps meaning; How one evaluates and follows a command; How one picks a role model; How one perceives the world.

    Here, video games are not hobbies or pure recreation; they are vehicles for art, sex, and race and class politics.The sixteen contributors are entrenched—they are the video game creators themselves, media critics, and Internet celebrities. They share one thing: they are all players at heart, handpicked to form a superstar roster by Daniel Goldberg and Linus Larsson, the authors of the bestselling Minecraft: The Unlikely Tale of Markus "Notch" Persson and the Game that Changed Everything.The State of Play is essential reading for anyone interested in what may well be the defining form of cultural expression of our time.

    Whether it is recounting the struggles over the game"Tetris," offering blow-by-blow narrative of Nintendo's bitter legal warfare or its see-saw competition with other companies for market leadership, Game Over is a masterful piece of business journalism and technical reportage-a book both cautionary and hugely entertaining.

    But as the field evolves, designers enter the field from many disciplines. Practitioners today have enough experience in UI design that they have been exposed to design rules, but it is essential that they understand the psychology behind the rules in order to effectively apply them. In "Designing with the Mind in Mind," Jeff Johnson, author of the best selling "GUI Bloopers," provides designers with just enough background in perceptual and cognitive psychology that UI design guidelines make intuitive sense rather than being just a list of rules to follow. * The first practical, all-in-one source for practitioners on user interface design rules and why, when and how to apply them.* Provides just enough background into the reasoning behind interface design rules that practitioners can make informed decisions in every project.* Gives practitioners the insight they need to make educated design decisions when confronted with tradeoffs, including competing design rules, time constrictions, or limited resources.

    The Humane Interface is a gourmet dish from a master chef. Five mice! --Jakob Nielsen, Nielsen Norman Group Author of Designing Web Usability: The Practice of Simplicity This unique guide to interactive system design reflects the experience and vision of Jef Raskin, the creator of the Apple Macintosh. Other books may show how to use todays widgets and interface ideas effectively. Raskin, however, demonstrates that many current interface paradigms are dead ends, and that to make computers significantly easier to use requires new approaches. He explains how to effect desperately needed changes, offering a wealth of innovative and specific interface ideas for software designers, developers, and product managers. The Apple Macintosh helped to introduce a previous revolution in computer interface design, drawing on the best available technology to establish many of the interface techniques and methods now universal in the computer industry. With this book, Raskin proves again both his farsightedness and his practicality. He also demonstrates how design ideas must be bui

    The authors' enthusiasm for their subject is compelling as they present abstract concepts in a humorous and easy-to-grasp fashion. Together, these books will open new doors of thought to anyone who wants to find out what computing is really about. The Little Schemer introduces computing as an extension of arithmetic and algebra; things that everyone studies in grade school and high school. It introduces programs as recursive functions and briefly discusses the limits of what computers can do. The authors use the programming language Scheme, and interesting foods to illustrate these abstract ideas. The Seasoned Schemer informs the reader about additional dimensions of computing: functions as values, change of state, and exceptional cases. The Little LISPer has been a popular introduction to LISP for many years. It had appeared in French and Japanese. The Little Schemer and The Seasoned Schemer are worthy successors and will prove equally popular as textbooks for Scheme courses as well as companion texts for any complete introductory course in Computer Science.

    We have Mindstorms to thank for that. In this book, pioneering computer scientist Seymour Papert uses the invention of LOGO, the first child-friendly programming language, to make the case for the value of teaching children with computers. Papert argues that children are more than capable of mastering computers, and that teaching computational processes like de-bugging in the classroom can change the way we learn everything else. He also shows that schools saturated with technology can actually improve socialization and interaction among students and between students and teachers.
