    Warnings of various and imminent environmental consequences dominated the news. Deepwater drilling—largely ignored or misunderstood to that point—exploded in the American consciousness in the worst way possible. Fire on the Horizon, written by veteran oil rig captain John Konrad and longtime Washington Post journalist Tom Shroder, recounts in vivid detail the life of the rig itself, from its construction in South Korea in the year 2000 to its improbable journey around the world to its disastrous end, and reveals the day-to-day lives, struggles, and ambitions of those who called it home. From the little-known maritime colleges to Transocean's training schools and Houston headquarters to the small towns all over the country where the wives and children of the Horizon's crew lived in the ever-present shadow of risk hundreds of miles away, Fire on the Horizon offers full-scale portraits of the Horizon's captain, its chief mate, its chief mechanic, and others. What emerges is a white-knuckled chronicle of engineering hubris at odds with the earth itself, an unusual manifestation of corporate greed and the unforgettable heroism of the men and women on board the Deepwater Horizon. Here is the harrowing minute-by-minute account of the fateful day, April 20, 2010, when the half-billion-dollar rig blew up, taking with it the lives of eleven people and leaving behind a swath of unprecedented natural destruction.

    Even as it guides us across town, GPS helps land planes, route mobile calls, anticipate earthquakes, predict weather, locate oil deposits, measure neutrinos, grow our food, and regulate global finance. It is as ubiquitous and essential as another Cold War technology, the Internet. In Pinpoint, Greg Milner takes us on a fascinating tour of a hidden system that touches almost every aspect of our modern life.While GPS has brought us breathtakingly accurate information about our planetary environment and physical space, it has also created new forms of human behavior. We have let it saturate the world’s systems so completely and so quickly that we are just beginning to confront the possible consequences. A single GPS timing flaw, whether accidental or malicious, could bring down the electrical grid, hijack drones, or halt the world financial system. The use, and potential misuse, of GPS data by government and corporations raise disturbing questions about ethics and privacy. GPS may be altering the nature of human cognition—possibly even rearranging the gray matter in our heads.Pinpoint tells the sweeping story of GPS from its conceptual origins as a bomb guidance system to its presence in almost everything we do. Milner examines the different ways humans have understood physical space, delves into the neuroscience of cognitive maps, and questions GPS’s double-edged effect on our culture. A fascinating and original story of the scientific urge toward precision, Pinpoint offers startling insight into how humans understand their place in the world.

    WikiLeaks brought to light a new form of whistleblowing, using powerful cryptographic code to hide leakers’ identities while they spill the private data of government agencies and corporations. But that technology has been evolving for decades in the hands of hackers and radical activists, from the libertarian enclaves of Northern California to Berlin to the Balkans. And the secret-killing machine continues to evolve beyond WikiLeaks, as a movement of hacktivists aims to obliterate the world’s institutional secrecy.This is the story of the code and the characters—idealists, anarchists, extremists—who are transforming the next generation’s notion of what activism can be.With unrivaled access to such major players as Julian Assange, Daniel Domscheit-Berg, and WikiLeaks’ shadowy engineer known as the Architect, never before interviewed, reporter Andy Greenberg unveils the world of politically-motivated hackers—who they are and how they operate.

    The complexity of nature's shapes differs in kind, not merely degree, from that of the shapes of ordinary geometry, the geometry of fractal shapes.Now that the field has expanded greatly with many active researchers, Mandelbrot presents the definitive overview of the origins of his ideas and their new applications. The Fractal Geometry of Nature is based on his highly acclaimed earlier work, but has much broader and deeper coverage and more extensive illustrations.

    Conflict between humans and machines is seen as inevitable and its outcome all too predictable.In this groundbreaking book, distinguished AI researcher Stuart Russell argues that this scenario can be avoided, but only if we rethink AI from the ground up. Russell begins by exploring the idea of intelligence in humans and in machines. He describes the near-term benefits we can expect, from intelligent personal assistants to vastly accelerated scientific research, and outlines the AI breakthroughs that still have to happen before we reach superhuman AI. He also spells out the ways humans are already finding to misuse AI, from lethal autonomous weapons to viral sabotage.If the predicted breakthroughs occur and superhuman AI emerges, we will have created entities far more powerful than ourselves. How can we ensure they never, ever, have power over us? Russell suggests that we can rebuild AI on a new foundation, according to which machines are designed to be inherently uncertain about the human preferences they are required to satisfy. Such machines would be humble, altruistic, and committed to pursue our objectives, not theirs. This new foundation would allow us to create machines that are provably deferential and provably beneficial.In a 2014 editorial co-authored with Stephen Hawking, Russell wrote, "Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last." Solving the problem of control over AI is not just possible; it is the key that unlocks a future of unlimited promise.

    This long-awaited revision contains changes throughout the text. There are new implementations of most of the major programming systems in the book, including the interpreters and compilers, and the authors have incorporated many small changes that reflect their experience teaching the course at MIT since the first edition was published. A new theme has been introduced that emphasizes the central role played by different approaches to dealing with time in computational models: objects with state, concurrent programming, functional programming and lazy evaluation, and nondeterministic programming. There are new example sections on higher-order procedures in graphics and on applications of stream processing in numerical programming, and many new exercises. In addition, all the programs have been reworked to run in any Scheme implementation that adheres to the IEEE standard.

    Whether exploring electromagnetic fields, the origin of hot chocolate, or DNA fingerprinting, these essays all illustrate the surprisingly circular nature of change. In "Room with (Half) a View," for instance, Burke muses about the partly obscured railway bridge outside his home on the Thames, a musing which sets off a chain of thought that leads from the bridge's engineer to Samuel Morse, to firearms inventor Sam Colt, and finally to a trombonist named Gustav Holst, who once lived in the very house that blocks Burke's view. So it goes with Burke's entertaining and informative essays as each one highlights the interconnectedness of seemingly unrelated events and innovations. Romantic poetry leads to brandy distillation; tonic water connects through Leibniz to the first explorers to reach the North Pole. This unique collection is sure to stimulate and delight history buffs, technophiles, and anyone else with a healthy intellectual curiosity.

    There she saw first-hand how deeply intertwined Silicon Valley was with the federal government, and always had been, and how shallow the common understanding of the secrets of the Valley's success actually was. Now, after almost five years of pioneering research, O'Mara has produced the definitive history of Silicon Valley for our time, the story of mavericks and visionaries, but also of powerful institutions creating the framework for innovation, from the Pentagon to Stanford University. It is also a story of a community that started off remarkably homogeneous and elitist and stayed that way, and whose belief in its own mythology has deepened into a collective hubris that has led to astonishing triumphs as well as devastating second-order effects.Deploying a wonderfully rich and diverse cast of protagonists, from the justly famous to the unjustly obscure, across four generations of explosive growth in the Valley, from the Forties to the present, O'Mara has wrestled into magnificent narrative form one of the most fateful developments in modern American history. She is on the ground with all of the key tech companies, and chronicles the evolution in their offerings through each successive era, and she has a profound fingertip feel for the politics of the sector, and its relation to the larger cultural narrative about tech as it has evolved over the years. Perhaps most impressively, O'Mara has penetrated the inner kingdom of tech venture capital firms, the insular and still remarkably old-boy world that became the cockpit of American capitalism and the crucible for bringing technological innovation to market, or not. The transformation of big tech into the engine room of the American economy and the nexus of so many of our hopes and dreams--and increasingly nightmares--can be understood, in Margaret O'Mara's masterful hands, as the story of one California valley. As her majestic history makes clear, its fate is the fate of us all.

    They gleefully whip the media into a frenzy over a fake teen drug crisis; they post offensive messages on Facebook memorial pages, traumatizing grief-stricken friends and family; they use unabashedly racist language and images. They take pleasure in ruining a complete stranger's day and find amusement in their victim's anguish. In short, trolling is the obstacle to a kinder, gentler Internet. To quote a famous Internet meme, trolling is why we can't have nice things online.Or at least that's what we have been led to believe. In this provocative book, Whitney Phillips argues that trolling, widely condemned as obscene and deviant, actually fits comfortably within the contemporary media landscape. Trolling may be obscene, but, Phillips argues, it isn't all that deviant. Trolls' actions are born of and fueled by culturally sanctioned impulses -- which are just as damaging as the trolls' most disruptive behaviors.Phillips describes, for example, the relationship between trolling and sensationalist corporate media -- pointing out that for trolls, exploitation is a leisure activity; for media, it's a business strategy. She shows how trolls, "the grimacing poster children for a socially networked world," align with social media. And she documents how trolls, in addition to parroting media tropes, also offer a grotesque pantomime of dominant cultural tropes, including gendered notions of dominance and success and an ideology of entitlement. We don't just have a trolling problem, Phillips argues; we have a culture problem. This Is Why We Can't Have Nice Things isn't only about trolls; it's about a culture in which trolls thrive.

    Many still vividly remember exactly where they were and what they were doing when they heard about the tragedy. In The Challenger Launch Decision, Diane Vaughan recreates the steps leading up to that fateful decision, contradicting conventional interpretations to prove that what occurred at NASA was not skulduggery or misconduct but a disastrous mistake.Journalists and investigators have historically cited production problems and managerial wrong-doing as the reasons behind the disaster. The Presidential Commission uncovered a flawed decision-making process at the space agency as well, citing a well-documented history of problems with the O-ring and a dramatic last-minute protest by engineers over the Solid Rocket Boosters as evidence of managerial neglect.Why did NASA managers, who not only had all the information prior to the launch but also were warned against it, decide to proceed? In retelling how the decision unfolded through the eyes of the managers and the engineers, Vaughan uncovers an incremental descent into poor judgment, supported by a culture of high-risk technology. She reveals how and why NASA insiders, when repeatedly faced with evidence that something was wrong, normalized the deviance so that it became acceptable to them.No safety rules were broken. No single individual was at fault. Instead, the cause of the disaster is a story not of evil but of the banality of organizational life. This powerful work explains why the Challenger tragedy must be reexamined and offers an unexpected warning about the hidden hazards of living in this technological age.

    Twelve astronauts made this greatest of all journeys and were indelibly marked by it, for better or for worse. Journalist Andrew Smith tracks down the nine surviving members of this elite group to find their answers to the question "Where do you go after you've been to the Moon?"A thrilling blend of history, reportage, and memoir, Moondust rekindles the hopeful excitement of an incandescent hour in America's past and captures the bittersweet heroism of those who risked everything to hurl themselves out of the known world -- and who were never again quite able to accept its familiar bounds.

    It was a thrilling era of open cockpits, silk scarves, leather helmets, and goggles. After serving in World War II, Sutter joined Boeing, then a small company, eager to build airplanes.In July 1965, he was asked to lead the large Boeing team designing the new 747. Pan Am wanted a new airliner as quickly as possible. This all-new transport had to be far bigger than anything in service or even on anybody's drawing board. To make it fly, Sutter and his team would have to push far beyond the technological boundaries of the late 1960s. Could it be done?Almost everything about the 747 would be unprecedented. Its cabin would be so wide that it would need two aisles. Its horizontal tail would be bigger than the wings of most airliners ever built. Jet engines big enough to lift it off the ground didn't yet exist. Runways at the world's airports couldn't handle it, and neither could Boeing's factories. They had to erect the world's largest building just to produce it. A truly mammoth undertaking, the 747 became one of the most successful airplane models ever.Sutter's vivid narrative takes us back to a time when American technology was cutting-edge -- the 747 came on the market the same year that men first set foot on the moon -- and jet travel was still glamorous and new. With wit and warmth, he gives an insider's sense of the larger-than-life-size personalities -- and the tensions -- in the aeronautical world. Ultimately, 747 is an inspiring story of grit and glory.
