His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century.Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

    Banks, telecommunications companies, and critical government networks (including the British Parliament and the French and German military) were infected. No one had ever seen anything like it. By January 2009 the worm lay hidden in at least eight million computers and the botnet of linked computers that it had created was big enough that an attack might crash the world. This is the gripping tale of the group of hackers, researches, millionaire Internet entrepreneurs, and computer security experts who united to defend the Internet from the Conficker worm: the story of the first digital world war.

    Today's increasingly fast pace of software development--as programmers make small changes to software one day only to undo them the next--has only heightened the problem; consecutive work on code or single-programmer software is a rare sight these days. Without careful attention to version control, concurrent and collaborative work can create more headaches than it solves. This is where Subversion comes into play.Written by members of the Subversion open source development team, Version Control with Subversion introduces the powerful new versioning tool designed to be the successor to the Concurrent Version System or CVS. CVS users will find the "look and feel" Subversion comfortably familiar, but under the surface it's far more flexible, robust, and usable, and more importantly, it improves on CVS's more notable flaws.The book begins with a general introduction to Subversion, the basic concepts behind version control, and a guided tour of Subversion's capabilities and structure. With thorough attention to detail, the authors cover every aspect of installing and configuring Subversion for managing a programming project, documentation, or any other team-based endeavor. Later chapters cover the more complex topics of branching, repository administration, and other advanced features such as properties, externals, and access control. The book ends with reference material and appendices covering a number of useful topics such as a Subversion complete reference and troubleshooting guide.Version Control with Subversion aims to be useful to readers of widely different backgrounds, from those with no previous experience in version control to experienced sysadmins. If you've never used version control, you'll find everything you need to get started in this book. And if you're a seasoned CVS pro, this book will help you make a painless leap into Subversion.

    In a 1995 interview, the late Steve Jobs claimed that the secret to his and Apple’s success was talent. “We’ve gone to exceptional lengths to hire the best people,” he said, believing that the talented resource was twenty-five times more valuable than an average alternative. For Microsoft founder Bill Gates, the multiple was even higher:A great lathe operator commands several times the wage of an average lathe operator, but a great writer of software code is worth 10,000 times the price of an average software writer.While the actual number might be up for debate, the importance of technical talent is not. The most successful companies today are those that understand the strategic role that developers will play in their success or failure. Not just successful technology companies – virtually every company today needs a developer strategy. There’s a reason that ESPN and Sears have rolled out API programs, that companies are being bought not for their products but their people. The reason is that developers are the most valuable resource in business.How did we get here? How did developers become the most important constituency in business seemingly overnight? The New Kingmakers explores the rise of the developer class, its implications and provides suggestions for navigating the new developer-centric landscape.

    Named one of the greatest minds of the 20th century by Time, Tim Berners-Lee is responsible for one of that century's most important advancements: the world wide web.  Now, this low-profile genius - who never personally profited from his invention - offers a compelling portrait of his invention.  He reveals the Web's origins and the creation of the now ubiquitous http and www acronyms and shares his views on such critical issues as censorship, privacy, the increasing power of software companies, and the need to find the ideal balance between commercial and social forces.  He offers insights into the true nature of the Web, showing readers how to use it to its fullest advantage.  And he presents his own plan for the Web's future, calling for the active support and participation of programmers, computer manufacturers, and social organizations to manage and maintain this valuable resource so that it can remain a powerful force for social change and an outlet for individual creativity.

    Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, Google's change in policy is symptomatic of the most significant shift to take place on the Web in recent years - the rise of personalization. In this groundbreaking investigation of the new hidden Web, Pariser uncovers how this growing trend threatens to control how we consume and share information as a society-and reveals what we can do about it.Though the phenomenon has gone largely undetected until now, personalized filters are sweeping the Web, creating individual universes of information for each of us. Facebook - the primary news source for an increasing number of Americans - prioritizes the links it believes will appeal to you so that if you are a liberal, you can expect to see only progressive links. Even an old-media bastion like "The Washington Post" devotes the top of its home page to a news feed with the links your Facebook friends are sharing. Behind the scenes a burgeoning industry of data companies is tracking your personal information to sell to advertisers, from your political leanings to the color you painted your living room to the hiking boots you just browsed on Zappos.In a personalized world, we will increasingly be typed and fed only news that is pleasant, familiar, and confirms our beliefs - and because these filters are invisible, we won't know what is being hidden from us. Our past interests will determine what we are exposed to in the future, leaving less room for the unexpected encounters that spark creativity, innovation, and the democratic exchange of ideas.While we all worry that the Internet is eroding privacy or shrinking our attention spans, Pariser uncovers a more pernicious and far-reaching trend on the Internet and shows how we can - and must - change course. With vivid detail and remarkable scope, The Filter Bubble reveals how personalization undermines the Internet's original purpose as an open platform for the spread of ideas and could leave us all in an isolated, echoing world.

    Along the way, we encounter black holes, turtles, snakes, dragons, axe-sharpening, and yak-shaving—and take a guided tour through the theories and methods, both brilliant and misguided, that litter the history of software development, from the famous ‘mythical man-month’ to Extreme Programming. Not just for technophiles but for anyone captivated by the drama of invention, Dreaming in Code offers a window into both the information age and the workings of the human mind.

    He reveals for the first time the details of the family's vast political network, which gave it access to and influence over many of the greatest statesmen of the age. And he tells a family saga, tracing the importance of unity and the profound role of Judaism in the lives of a dynasty that rose from the confines of the Frankfurt ghetto and later used its influence to assist oppressed Jews throughout Europe. A definitive work of impeccable scholarship with a thoroughly engaging narrative, 'The House of Rothschild' is a biography of the rarest kind, in which mysterious and fascinating historical figures finally spring to life.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

    Just over fifteen years later, he had transformed himself into the charismatic CEO of a company worth $47 billion--at least on paper. With his long hair and feel-good mantras, the 6-foot-five Neumann, who grew up in part on a kibbutz, looked the part of a messianic Silicon Valley entrepreneur. The vision he offered was mesmerizing: a radical reimagining of work space for a new generation, with its fluid jobs and lax office culture. He called it WeWork. Though the company was merely subleasing amenity-filled office space to freelancers and small startups, Neumann marketed it like a revolutionary product--and investors swooned.As billions of funding dollars poured in, Neumann's ambitions grew limitless. WeWork wasn't just an office space provider, he boasted. It would build schools, create WeWork cities, even colonize Mars. Could he, Neumann wondered from the ice bath he'd installed in his office, become the first trillionaire or a world leader? In pursuit of its founder's grandiose vision, the company spent money faster than it could bring it in. From his private jet, sometimes clouded with marijuana smoke, the CEO scoured the globe for more capital. In late 2019, just weeks before WeWork's highly publicized IPO, a Hail Mary effort to raise cash, everything fell apart. Neumann was ousted from his company--but still was poised to walk away a billionaire.Calling to mind the recent demise of Theranos and the hubris of the dotcom era bust, WeWork's extraordinary rise and staggering implosion were fueled by disparate characters in a financial system blind to its risks, from a Japanese billionaire with designs on becoming the Warren Buffet of tech, to leaders at JPMorgan and Goldman Sachs who seemed intoxicated by a Silicon Valley culture where sensible business models lost out to youthful CEOs who promised disruption. Why did some of the biggest names in banking and venture capital buy the hype? And what does the future hold for Silicon Valley unicorns? Wall Street Journal reporters Eliot Brown and Maureen Farrell explore these questions in this definitive account of WeWork's unraveling.

    Max 'Vision' Butler was a white-hat hacker and a celebrity throughout the programming world, even serving as a consultant to the FBI. But there was another side to Max. As the black-hat 'Iceman', he'd seen the fraudsters around him squabble, their ranks riddled with infiltrators, their methods inefficient, and in their dysfunction was the ultimate challenge: he would stage a coup and steal their ill-gotten gains from right under their noses.Through the story of Max Butler's remarkable rise, KINGPIN lays bare the workings of a silent crime wave affecting millions worldwide. It exposes vast online-fraud supermarkets stocked with credit card numbers, counterfeit cheques, hacked bank accounts and fake passports. Thanks to Kevin Poulsen's remarkable access to both cops and criminals, we step inside the quiet,desperate battle that law enforcement fights against these scammers. And learn that the boy next door may not be all he seems.

    And few individuals have done more to shape Silicon Valley than Peter Thiel. The billionaire venture capitalist and entrepreneur has been a behind-the-scenes operator influencing countless aspects of our contemporary way of life, from the technologies we use every day to the delicate power balance between Silicon Valley, Wall Street, and Washington. But despite his power and the ubiquity of his projects, no public figure is quite so mysterious.In the first major biography of Thiel, Max Chafkin traces the trajectory of the innovator's singular life and worldview, from his upbringing as the child of immigrant parents and years at Stanford as a burgeoning conservative thought leader to his founding of PayPal and Palantir, early investment in Facebook and SpaceX, and relationships with fellow tech titans Mark Zuckerberg, Elon Musk, and Eric Schmidt. The Contrarian illuminates the extent to which Thiel has sought to export his values to the corridors of power beyond Silicon Valley, including funding the lawsuit that destroyed the blog Gawker and strenuously backing far-right political candidates, notably Donald Trump for president in 2016.Eye-opening and deeply reported, The Contrarian is a revelatory biography of a one-of-a-kind leader and an incisive portrait of a tech industry whose explosive growth and power is both thrilling and fraught with controversy.

    At the time, only three percent of Americans were online. It took a decade for AOL to achieve mainstream success, and there were many near-death experiences and back-to-the-wall pivots. AOL became the top performing company of the 1990s, and at its peak more than half of all consumer internet traffic in the United States ran through the service. After Case engineered AOL’s merger with Time Warner and he became Chairman of the combined business, Case oversaw the biggest media and communications empire in the world. In The Third Wave, which pays homage to the work of the futurist Alvin Toffler (from whom Case has borrowed the title, and whose work inspired him as a young man), Case takes us behind the scenes of some of the most consequential and riveting business decisions of our time while offering illuminating insights from decades of working as an entrepreneur, an investor, a philanthropist, and an advocate for sensible bipartisan policies. We are entering, as Case explains, a new paradigm called the “Third Wave” of the internet. The first wave saw AOL and other companies lay the foundation for consumers to connect to the Internet. The second wave saw companies like Google and Facebook build on top of the Internet to create search and social networking capabilities, while apps like Snapchat and Instagram leverage the smartphone revolution. Now, Case argues, we’re entering the Third Wave: a period in which entrepreneurs will vastly transform major “real world” sectors like health, education, transportation, energy, and food—and in the process change the way we live our daily lives. But success in the Third Wave will require a different skill set, and Case outlines the path forward. The Third Wave is part memoir, part manifesto, and part playbook for the future. With passion and clarity, Case explains the ways in which newly emerging technology companies (a growing number of which, he argues, will not be based in Silicon Valley) will have to rethink their relationships with customers, with competitors, and with governments; and offers advice for how entrepreneurs can make winning business decisions and strategies—and how all of us can make sense of this changing digital age.
