Charles Perrow argues that the conventional engineering approach to ensuring safety--building in more warnings and safeguards--fails because systems complexity makes failures inevitable. He asserts that typical precautions, by adding to complexity, may help create new categories of accidents. (At Chernobyl, tests of a new safety system helped produce the meltdown and subsequent fire.) By recognizing two dimensions of risk--complex versus linear interactions, and tight versus loose coupling--this book provides a powerful framework for analyzing risks and the organizations that insist we run them.The first edition fulfilled one reviewer's prediction that it may mark the beginning of accident research. In the new afterword to this edition Perrow reviews the extensive work on the major accidents of the last fifteen years, including Bhopal, Chernobyl, and the Challenger disaster. The new postscript probes what the author considers to be the quintessential 'Normal Accident' of our time: the Y2K computer problem.

    Arthur looks at what are now the three best-known tech companies and through the voices of former and current staff examines their different strategies to try to win the battle to control the exploding network connecting the world. Microsoft was a giant -- soon to become the highest-valued company in the world, while Apple was a minnow and Google just a startup. By February 10 2012, Apple was worth more ($462bn) than both Microsoft ($258bn) and Google ($198bn) combined.The chance had come from tumultuous battles between the three. To win their battles: Apple used design, the vertical model of controlling the hardware and software and a relentless focus on the customer to the exclusion of others.Microsoft depended on the high quality of its employees' programming skills and its monopolies in software to try to move into new markets - such as search and music.Google focused on being quick, efficient and using the power of data analysis - not human "taste" - to make decisions and get ahead of would-be rivals.With exclusive information from interviews with current and former employees of the three companies Arthur also addresses:- What the inventors of the hard drive used in the iPod thought it would really be used for- How Apple transformed the smartphone market- Which of Android or Apple forced Microsoft to abandon Windows Mobile- What happened to Microsoft's tablet plans

    Half of twelve-year-olds regularly play violent, Mature-rated games. And parents are worried... "I don't know if it's an addiction, but my son is just glued to it. It's the same with my daughter with her computer... and I can't be watching both of them all the time, to see if they're talking to strangers or if someone is getting killed in the other room on the PlayStation. It's just nerve-racking!" "I'm concerned that this game playing is just the kid and the TV screen... how is this going to affect his social skills?""I'm not concerned about the violence; I'm concerned about the way they portray the violence. It's not accidental; it's intentional. They're just out to kill people in some of these games." What should we as parents, teachers and public policy makers be concerned about? The real risks are subtle and aren't just about gore or sex. Video games don't affect all children in the same way; some children are at significantly greater risk. (You may be surprised to learn which ones!) Grand Theft Childhood gives parents practical, research-based advice on ways to limit many of those risks. It also shows how video games -- even violent games -- can benefit children and families in unexpected ways.In this groundbreaking and timely book, Drs. Lawrence Kutner and Cheryl Olson cut through the myths and hysteria, and reveal the surprising truth about kids and violent games.

    The principal enhancement in Java 8 was the addition of functional programming constructs to Java's object-oriented roots. Java 7, 8, and 9 also introduced language features, such as the try-with-resources statement, the diamond operator for generic types, default and static methods in interfaces, the @SafeVarargs annotation, and modules. New library features include pervasive use of functional interfaces and streams, the java.time package for manipulating dates and times, and numerous minor enhancements such as convenience factory methods for collections. In this new edition of Effective Java, Bloch updates the work to take advantage of these new language and library features, and provides specific best practices for their use. Java's increased support for multiple paradigms increases the need for best-practices advice, and this book delivers. As in previous editions, each chapter consists of several "items," each presented in the form of a short, standalone essay that provides specific advice, insight into Java platform subtleties, and updated code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why. Coverage includes:Updated techniques and best practices on classic topics, including objects, classes, methods, libraries, and generics How to avoid the traps and pitfalls of commonly misunderstood subtleties of the platform Focus on the language and its most fundamental libraries, such as java.lang and java.util

    This book draws on material Michael created for his renowned Object Mentor seminars, techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy systems under control.

    "An immensely fun and -- one cannot emphasize this enough -- accessible history of the first outlaws in cyberspace."--Glamour

    It features a novel way of teaching interactive designers how to create and improve their designs to incorporate the highest degree of fun. As the book shows, designing for fun is all about making interactive products like games highly entertaining, engaging, and addictive. The book's unique approach of providing a highly visual storyboard approach combined with a narrative on the art and practice of designing for fun is sure to be a hit with game and interactive designers.At first glance A Theory of Fun for Game Design is a book that will truly inspire and challenge game designers to think in new ways; however, its universal message will influence designers from all walks of life. This book captures the real essence of what drives us to seek out products and experiences that are truly fun and entertaining. The author masterfully presents his engaging theory by showing readers how many designs are lacking because they are predictable and not engaging enough. He then explains how great designers use different types of elements in new ways to make designs more fun and compelling. Anyone who is interested in design will enjoy how the book works on two levels--as a quick inspiration guide to game design, or as an informative discussion that details the insightful thinking from a great mind in the game industry.

    pThe benefits of our recently arrived-at state of connectivity have been myriad from the ease with which it has been possible to buy a new house to the convenience of borrowing and investing money profitably. But the luxuries of the connected age have taken on a momentum all of their own. By counter-intuitively anatomizing how being overconnected tends to create systems of positive feedback that have largely negative consequences, Davidow explains everything from the recent Subprime mortgage crisis to the meltdown of Iceland, from the loss of people s privacy to the spectacular fall of the stock market. All because we were so miraculously wired together.pExplaining how such symptoms of Internet connection as unforeseeable accidents and how thought contagions acted to accelerate the downfall and make us permanently vulnerable to catastrophe, Davidow places our recent experience in historical perspective and offers a set of practical steps to minimize similar disasters in the future.pWilliam Davidow is a successful Silicon Valley venture capitalist, philanthropist, and author, and as a senior vice-president of Intel Corporation, he was responsible for the design of the Intel microprocessor chip. He has written three previous books Marketing High Technology (The Free Press, 1986) and Total Customer Service (Harper, 1989), both with Bro Uttal, and The Virtual Corporation" (Harper, 1992), with Michael Malone as well as columns for Forbes and numerous op-ed pieces. He graduated from Dartmouth College, has a masters degree from the California Institute of Technology, and a Ph.D. from Stanford University.
