From the acclaimed Vanity Fair and GQ journalist--an unprecedented, in-depth portrait of the man whose return to Apple precipitated one of the biggest turnarounds in business history. From the emergence of Apple Computer in the late 1970s and early 1980s to its current resurgence, charismatic leader Steve Jobs has captivated the public. Both revered and reviled for his dictatorial manner and stunning successes, Jobs has transcended his legend in Silicon Valley to take on some of the heaviest hitters in Hollywood. Now, in The Second Coming of Steve Jobs, Alan Deutschman presents the most revealing portrait yet of this fascinating, complex character--an in-depth look at the many layers of Steve Jobs, a man who is at turns a brilliant cult figure and an abusive, egomaniacal kid. This story begins back in 1985 when Jobs was exiled from Apple, and then it goes on to chronicle the rise and fall of his own company, NeXT; the enormous success of Jobs's film animation studio, Pixar; and finally his triumphant return to Apple in the late 1990s, with Jobs taking the title of CEO in January 2000. Displaying an uncanny skill at the negotiation table and an intuitive sense of brilliant design that could capture the public's fascination with products like the iMac, along with a celebrity's ability to command the spotlight, Jobs has been able to catapult himself to the top of the Silicon Valley and Hollywood establishments. Based on interviews with scores of people--rivals, colleagues, friends--who have worked with Jobs over the years, The Second Coming of Steve Jobs gets under the hood of this extraordinarily complex man: how and why he almost gave up on his career; the details of his negotiations with Disney's Jeffrey Katzenberg and Michael Eisner, and of the culture clash between Silicon Valley and Hollywood; his methods of leadership, management, creativity, and innovation; his friendship and rivalry with Bill Gates--and much more. In an unsentimental and powerful voice, Deutschman reveals a man who suffered his midlife crisis at thirty, compressing it into just three months; struggled between self-imposed exile and the allure of public life; and became the baby boomer icon who was constantly blurring the lines between businessman, rock star, and beatnik. The Second Coming of Steve Jobs is a compelling look at an individual who has changed the face of technology and entertainment for the twenty-first century. This candid account of Steve Jobs's tumultuous and provocative career will answer the many questions left unanswered by this incredibly private character who has come to represent the Silicon Valley American dream.
Ludlow and Wallace take us behind the scenes of the Herald as they report on the emergence of a fascinating universe of virtual spaces that will become the next generation of the World Wide Web: a 3-D environment that provides richer, more expressive interactions than the Web we know today.
We've always dreamed of perfect places: Eden, heaven, Oz Â- places over the rainbow, beyond death and loss. Now, through computer technology, we can inhabit those worlds together. Each week, between 35 and 50 million people worldwide abandon reality for virtual worlds. In Boston, Massachusetts, a group of nine disabled men and women inhabit one virtual body, which frees them from their lifelong struggle to be seen and heard. The Pentagon has begun to develop virtual worlds to help in real-world battles. In Korea, where one particular game has 8 million residents, virtual violence has spread into the real world. Fortunes have been made, and mafia gangs have emerged to muscle in on the profits. In these new computer-generated places, which at first glance seem free from trouble and sorrow, you can create a new self. With the click of a mouse you can select eye colour, face shape, height, even wings. You can build houses, make and sell works of art, earn real money, get married and divorced. On websites like eBay, people sell virtual clothes and rent virtual property for real cash - for a total of £400 million worth each year. Tim Guest takes us on a revelatory journey through the electronic looking-glass, as he investigates one of the most bizarre phenomena of the 21st century.
A revolution is under way.<P> In recent years, Google's autonomous cars have logged thousands of miles on American highways and IBM's Watson trounced the best human Jeopardy! players. Digital technologies--with hardware, software, and networks at their core--will in the near future diagnose diseases more accurately than doctors can, apply enormous data sets to transform retailing, and accomplish many tasks once considered uniquely human.<P> In The Second Machine Age MIT's Erik Brynjolfsson and Andrew McAfee--two thinkers at the forefront of their field--reveal the forces driving the reinvention of our lives and our economy. As the full impact of digital technologies is felt, we will realize immense bounty in the form of dazzling personal technology, advanced infrastructure, and near-boundless access to the cultural items that enrich our lives.<P> Amid this bounty will also be wrenching change. Professions of all kinds--from lawyers to truck drivers--will be forever upended. Companies will be forced to transform or die. Recent economic indicators reflect this shift: fewer people are working, and wages are falling even as productivity and profits soar.<P> Drawing on years of research and up-to-the-minute trends, Brynjolfsson and McAfee identify the best strategies for survival and offer a new path to prosperity. These include revamping education so that it prepares people for the next economy instead of the last one, designing new collaborations that pair brute processing power with human ingenuity, and embracing policies that make sense in a radically transformed landscape.<P> A fundamentally optimistic book, The Second Machine Age will alter how we think about issues of technological, societal, and economic progress.
While the global economy languishes, one place just keeps growing despite failing banks, uncertain markets, and high unemployment: Silicon Valley. In the last two years, more than 100 incubators have popped up there, and the number of angel investors has skyrocketed. Today, 40 percent of all venture capital investments in the United States come from Silicon Valley firms, compared to 10 percent from New York. In Secrets of Silicon Valley, entrepreneur and media commentator Deborah Perry Piscione takes us inside this vibrant ecosystem where meritocracy rules the day. She explores Silicon Valley's exceptionally risk-tolerant culture, and why it thrives despite the many laws that make California one of the worst states in the union for business. Drawing on interviews with investors, entrepreneurs, and community leaders, as well as a host of case studies from Google to Paypal, Piscione argues that Silicon Valley's unique culture is the best hope for the future of American prosperity and the global business community and offers lessons from the Valley to inspire reform in other communities and industries, from Washington, DC to Wall Street.
Despite their myriad manifestations and different targets, nearly all attacks on computer systems have one fundamental cause: the code used to run far too many systems today is not secure. Flaws in its design, implementation, testing, and operations allow attackers all-too-easy access. Secure Coding: Principles & Practices looks at the problem of bad code in a new way. This concise and highly readable book is packed with advice based on the authors' decades of experience in the computer security field.

Human factors and usability issues have traditionally played a limited role in security research and secure systems development. Security experts have largely ignored usability issues--both because they often failed to recognize the importance of human factors and because they lacked the expertise to address them. But there is a growing recognition that today's security problems can be solved only by addressing issues of usability and human factors. Increasingly, well-publicized security breaches are attributed to human errors that might have been prevented through more usable software. Indeed, the world's future cyber-security depends upon the deployment of security technology that can be broadly used by untrained computer users. Still, many people believe there is an inherent trade-off between computer security and usability. It's true that a computer without passwords is usable, but not very secure. A computer that makes you authenticate every five minutes with a password and a fresh drop of blood might be very secure, but nobody would use it. Clearly, people need computers, and if they can't use one that's secure, they'll use one that isn't. Unfortunately, unsecured systems aren't usable for long, either. They get hacked, compromised, and otherwise rendered useless. There is increasing agreement that we need to design secure systems that people can actually use, but less agreement about how to reach this goal. Security and Usability is the first book-length work describing the current state of the art in this emerging field. Edited by security experts Dr. Lorrie Faith Cranor and Dr. Simson Garfinkel, and authored by cutting-edge security and human-computer interaction (HCI) researchers world-wide, this volume is expected to become both a classic reference and an inspiration for future research. Security and Usability groups 34 essays into six parts: Realigning Usability and Security-- with careful attention to user-centered design principles, security and usability can be synergistic. Authentication Mechanisms-- techniques for identifying and authenticating computer users. Secure Systems-- how system software can deliver or destroy a secure user experience. Privacy and Anonymity Systems-- methods for allowing people to control the release of personal information. Commercializing Usability: The Vendor Perspective-- specific experiences of security and software vendors (e.g., IBM, Microsoft, Lotus, Firefox, and Zone Labs) in addressing usability. The Classics-- groundbreaking papers that sparked the field of security and usability. This book is expected to start an avalanche of discussion, new ideas, and further advances in this important field.

As a system administrator or security professionals, you probably find yourself inundated each day with a deluge of log files from seemingly countless devices, servers, and applications on your network ranging from Windows Server to Snort to your PIX firewall and everything in between. At times, the task of "seeing the forest through the trees" to extract useful, repeatable information from these logs may seem almost impossible. This unique book will show you how to use a combination of open source software such as Tcpdstats, and Snort perfmonitor to create succinct, meaningful reports that give you the big picture of your network's overall health and well being. So, if you need to analyze and prioritize everything from how much of your bandwidth is devoted to browsing ESPN.com, to the most targeted machines in your IDS logs, this is the book for you. This book teaches IT professionals how to analyze, manage, and automate their security log files to generate useful, repeatable information that can be use to make their networks more efficient and secure using primarily open source tools. The book begins by discussing the "Top 10" security logs that every IT professional should be regularly analyzing. These 10 logs cover everything from the top workstations sending/receiving data through a firewall to the top targets of IDS alerts. The book then goes on to discuss the relevancy of all of this information. Next, the book describes how to script open source reporting tools like Tcpdstats to automatically correlate log files from the various network devices to the "Top 10" list. By doing so, the IT professional is instantly made aware of any critical vulnerabilities or serious degradation of network performance. All of the scripts presented within the book will be available for download from the Syngress Solutions Web site.
