    District Judge Stanley Sporkin. Teamed with the daughter of one of Bill Gates's closest associates, thirteen-year Microsoft veteran Marlin Eller shows us what it was like at every step along Gates's route to world domination, making all that's been written before seem like a rough guess. If the Justice Department had Eller and Edstrom investigating the current-headline-making antitrust case, they would have on the record many of Microsoft's most respected developers directly contradicting the "authorized" version of events being presented in court. They would know the real scoop on how Windows was developed in the first place, shedding new light on the 1988 Apple v. Microsoft lawsuit over the alleged copying of the Mac. They would even know the real story of how Microsoft killed off Go Corporation, told for the first time by the man who did the deed, Marlin Eller himself. Revealing the smoke-and-mirror deals, the palms greased to help launch a product that didn't exist, and the boneyard of once-thriving competitors targeted by the Gates juggernaut, this book demonstrates with often hilariously damning detail the Microsoft muddle that passes for strategic direction, offset by Gates's uncanny ability to come from behind to crush whoever's on top.

    individual whose contributions to the scientific, business and cultural realms are extensive."—BookpageBefore slim laptops that fit into briefcases, computers looked like strange, alien vending machines. But in "the most staggering burst of technical invention by a single person in high-tech history" (BusinessWeek​) Steve Wozniak invented the first true personal computer. Wozniak teamed up with Steve Jobs, and Apple Computer was born, igniting the computer revolution and transforming the world. Here, thirty years later, the mischievous genius with the low profile treats readers to a rollicking, no-holds-barred account of his life—for once, in the voice of the wizard himself.

    But this book is different from all the others.Becoming Steve Jobs takes on and breaks down the existing myth and stereotypes about Steve Jobs. The conventional, one-dimensional view of Jobs is that he was half-genius, half-jerk from youth, an irascible and selfish leader who slighted friends and family alike. Becoming Steve Jobs answers the central question about the life and career of the Apple cofounder and CEO: How did a young man so reckless and arrogant that he was exiled from the company he founded become the most effective visionary business leader of our time, ultimately transforming the daily life of billions of people?Drawing on incredible and sometimes exclusive access, Schlender and Tetzeli tell a different story of a real human being who wrestled with his failings and learned to maximize his strengths over time. Their rich, compelling narrative is filled with stories never told before from the people who knew Jobs best, and who decided to open up to the authors, including his family, former inner circle executives, and top people at Apple, Pixar and Disney, most notably Tim Cook, Jony Ive, Eddy Cue, Ed Catmull, John Lasseter, Robert Iger and many others. In addition, Brent knew Jobs personally for 25 years and draws upon his many interviews with him, on and off the record, in writing the book. He and Rick humanize the man and explain, rather than simply describe, his behavior. Along the way, the book provides rich context about the technology revolution we all have lived through, and the ways in which Jobs changed our world.Schlender and Tetzeli make clear that Jobs's astounding success at Apple was far more complicated than simply picking the right products: he became more patient, he learned to trust his inner circle, and discovered the importance of growing the company incrementally rather than only shooting for dazzling game-changing products.A rich and revealing account that will change the way we view Jobs, Becoming Steve Jobs shows us how one of the most colorful and compelling figures of our times was able to combine his unchanging, relentless passion with a more mature management style to create one of the most valuable and beloved companies on the planet.

    For centuries, such fears have been misplaced, and many economists maintain that they remain so today. But as Daniel Susskind demonstrates, this time really is different. Breakthroughs in artificial intelligence mean that all kinds of jobs are increasingly at risk.Drawing on almost a decade of research in the field, Susskind argues that machines no longer need to think like us in order to outperform us, as was once widely believed. As a result, more and more tasks that used to be far beyond the capability of computers – from diagnosing illnesses to drafting legal contracts, from writing news reports to composing music – are coming within their reach. The threat of technological unemployment is now real.This is not necessarily a bad thing, Susskind emphasizes. Technological progress could bring about unprecedented prosperity, solving one of humanity’s oldest problems: how to make sure that everyone has enough to live on. The challenges will be to distribute this prosperity fairly, to constrain the burgeoning power of Big Tech, and to provide meaning in a world where work is no longer the center of our lives. Perceptive, pragmatic, and ultimately hopeful, A World Without Work shows the way.

    But what is it physically? And where is it really? Our mental map of the network is as blank as the map of the ocean that Columbus carried on his first Atlantic voyage. The Internet, its material nuts and bolts, is an unexplored territory. Until now.In Tubes, journalist Andrew Blum goes inside the Internet's physical infrastructure and flips on the lights, revealing an utterly fresh look at the online world we think we know. It is a shockingly tactile realm of unmarked compounds, populated by a special caste of engineer who pieces together our networks by hand; where glass fibers pulse with light and creaky telegraph buildings, tortuously rewired, become communication hubs once again. From the room in Los Angeles where the Internet first flickered to life to the caverns beneath Manhattan where new fiber-optic cable is buried; from the coast of Portugal, where a ten-thousand-mile undersea cable just two thumbs wide connects Europe and Africa, to the wilds of the Pacific Northwest, where Google, Microsoft, and Facebook have built monumental data centers—Blum chronicles the dramatic story of the Internet's development, explains how it all works, and takes the first-ever in-depth look inside its hidden monuments.This is a book about real places on the map: their sounds and smells, their storied pasts, their physical details, and the people who live there. For all the talk of the "placelessness" of our digital age, the Internet is as fixed in real, physical spaces as the railroad or telephone. You can map it and touch it, and you can visit it. Is the Internet in fact "a series of tubes" as Ted Stevens, the late senator from Alaska, once famously described it? How can we know the Internet's possibilities if we don't know its parts?Like Tracy Kidder's classic The Soul of a New Machine or Tom Vanderbilt's recent bestseller Traffic, Tubes combines on-the-ground reporting and lucid explanation into an engaging, mind-bending narrative to help us understand the physical world that underlies our digital lives.

    Every company lives on it; no manager can control it. Everyone must learn to deal with it.Now, Geoffrey Moore, author of Crossing the Chasm and Inside the Tornado, two bestselling works that helped guide the high-tech revolution, explores the new management paradigms that will guide businesses in the twenty-first century, showing them how to survive and thrive on the fault line.In this long-awaited new book, Moore turns his attention to the most important question for businesses: How can companies that rose to prominence prior to the age of the Internet manage for shareholder value now that the Internet is upon us?The old management truths are dead. Business models that worked admirably until the last decade of the twentieth century must be replaced. The dotcoms are invading every sector of commerce, overturning established relationships, reengineering markets, attacking long-established price points, and disintermediating longstanding institutions.What should management do when it is under direct assault from companies no one ever heard of even a few years ago?In a book that will reset the management agenda in the age of the Internet, Moore shows why sensitivity to stock price is the single most important lever for managing in the future, both as a leading indicator of shifts in competitive advantage and as an employee motivator for making necessary changes in organizations heretofore impervious to change. He prescribes a new agenda for management teams that includesNew strategies for achieving and sustaining competitive advantageNew metrics to keep management teams on course with these strategiesA specific blueprint for how the blue-chip companies can meet the challenge of the dotcomsModels of organizational change for each stage of market developmentThe crucial role of declaring a culture inenabling swift response to global changeToday practically every company, whether inside the high-tech sector or not, is living on the fault line. By synthesizing his groundbreaking earlier work on the dynamics of technology-based markets with a new focus on managing publicly held corporations for shareholder value, Geoffrey Moore provides a highly prescriptive guide for any company struggling to manage the disruptive forces of the new economy.In Crossing the Chasm and Inside the Tornado, Moore created a new language for navigating the technology adoption life cycle. In Living on the Fault Line, he once again offers a brilliant set of navigational tools to help meet today's defining management challenge-managing for shareholder value in the age of the Internet.

    His job no longer existed. "I think they just want to hire younger people," his boss at Newsweek told him. Fifty years old and with a wife and two young kids, Dan was, in a word, screwed. Then an idea hit. Dan had long reported on Silicon Valley and the tech explosion. Why not join it? HubSpot, a Boston start-up, was flush with $100 million in venture capital. They offered Dan a pile of stock options for the vague role of "marketing fellow." What could go wrong? HubSpotters were true believers: They were making the world a better place ... by selling email spam. The office vibe was frat house meets cult compound: The party began at four thirty on Friday and lasted well into the night; "shower pods" became hook-up dens; a push-up club met at noon in the lobby, while nearby, in the "content factory," Nerf gun fights raged. Groups went on "walking meetings," and Dan's absentee boss sent cryptic emails about employees who had "graduated" (read: been fired). In the middle of all this was Dan, exactly twice the age of the average HubSpot employee, and literally old enough to be the father of most of his co-workers, sitting at his desk on his bouncy-ball "chair."Mixed in with Lyons's uproarious tale of his rise and fall at Hubspot is a trenchant analysis of the start-up world, a de facto conspiracy between those who start companies and those who fund them, a world where bad ideas are rewarded with hefty investments, where companies blow money lavishing perks on their post-collegiate workforces, and where everybody is trying to hang on just long enough to reach an IPO and cash out. With a cast of characters that includes devilish angel investors, fad-chasing venture capitalists, entrepreneurs and "wantrapreneurs," bloggers and brogrammers, social climbers and sociopaths, Disrupted is a gripping and definitive account of life in the (second) tech bubble.

    Johnson tell the definitive story of what has changed, what it means for businesses today, and how managers, entrepreneurs, and business owners can adapt and thrive in this new era.What do Google, Snapchat, Tinder, Amazon, and Uber have in common, besides soaring market share? They're platforms - a new business model that has quietly become the only game in town, creating vast fortunes for its founders while dominating everyone's daily life. A platform, by definition, creates value by facilitating an exchange between two or more interdependent groups. So, rather that making things, they simply connect people.The Internet today is awash in platforms - Facebook is responsible for nearly 25 percent of total Web visits, and the Google platform crash in 2013 took about 40 percent of Internet traffic with it. Representing the ten most trafficked sites in the U.S., platforms are also prominent over the globe; in China, they hold the top eight spots in web traffic rankings.The advent of mobile computing and its ubiquitous connectivity have forever altered how we interact with each other, melding the digital and physical worlds and blurring distinctions between "offline" and "online." These platform giants are expanding their influence from the digital world to the whole economy. Yet, few people truly grasp the radical structural shifts of the last ten years.

    At its core, a blockchain injects trust into the network, cutting off some intermediaries from serving that function and creatively disrupting how they operate. Metaphorically, blockchains are the ultimate non-stop computers. Once launched, they never go down, and offer an incredible amount of resiliency, making them dependable and attractive for running a new generation of decentralized services and software applications.The Business Blockchain charts new territory in advancing our understanding of the blockchain by unpacking its elements like no other before. William Mougayar anticipates a future that consists of thousands, if not millions of blockchains that will enable not only frictionless value exchange, but also a new flow of value, redefining roles, relationships, power and governance. In this book, Mougayar makes two other strategic assertions. First, the blockchain has polymorphic characteristics; its application will result in a multiplicity of effects. Second, we shouldn't ask ourselves what problems the blockchain solves, because that gives us a narrow view on its potential. Rather, we should imagine new opportunities, and tackle even more ambitious problems that cross organizational, regulatory and mental boundaries.Drawing on 34 years of technology industry experience as an executive, analyst, consultant, entrepreneur, startup mentor, author, blogger, educator, thought leader and investor, William Mougayar describes a future that is influenced by fundamental shifts brought by blockchain technology as the catalyst for change. William Mougayar has been described as the most sophisticated blockchain business thinker. He is a blockchain industry insider whose work has already shaped and influenced the understanding of blockchain for people around the world, via his generous blogging and rigorous research insights. He is a direct participant in the crypto-technology market, working alongside startups, entrepreneurs, pioneers, leaders, innovators, creators, enterprise executives and practitioners; in addition to being an investor, advisor, and board member in some of the leading organizations in this space, such as the Ethereum Foundation, OpenBazaar and Coin Center.Just as the Internet created new possibilities that we didn't foresee in its early years, the blockchain will give rise to new business models and ideas that may still be invisible. Following an engaging Foreword by Vitalik Buterin, this book is organized along these 7 chapters:1. What is the Blockchain?2. How Blockchain Trust Infiltrates3. Obstacles, Challenges & Mental Blocks4. Blockchain in Financial Services5. Lighthouse Industries & New Intermediaries6. Implementing Blockchain Technology7. Decentralization as the Way ForwardThe Business Blockchain is an invitation for technologists to better understand the business potential of the blockchain, and for business minded people to grasp the many facets of blockchain technology. This book teaches you how to think about the blockchain.
