    He has run the toughest city in America with an independence and show of ego that first brought him great success—and eventually threatened it. Yet while Bloomberg is internationally known and admired, few people know the man behind the carefully crafted public persona.In Mike Bloomberg, Joyce Purnick explores Mr. Bloomberg's life from his childhood in the suburbs of Boston, to his rise on Wall Street and the creation of Bloomberg L.P., to his mayoral record and controversial gamble on a third term. Drawing on her deep knowledge of New York City politics, and interviews with Bloomberg's friends, family, colleagues, and the mayor himself, she creates a textured portrait of one of the more complex men of our era.

    Young people are waiting longer to marry, to have children, and to choose a career direction. As a result, they enjoy more freedom, opportunities, and personal growth than ever before.But the transition to adulthood is also more complex, disjointed, and confusing.In Lost in Transition, Christian Smith and his collaborators draw on 230 in-depth interviews with a broad cross-section of emerging adults (ages 18-23) to investigate the difficulties young people face today, the underlying causes of those difficulties, and the consequences both for individuals andfor American society as a whole. Rampant consumer capitalism, ongoing failures in education, hyper-individualism, postmodernist moral relativism, and other aspects of American culture are all contributing to the chaotic terrain that emerging adults must cross. Smith identifies five major problemsfacing very many young people today: confused moral reasoning, routine intoxication, materialistic life goals, regrettable sexual experiences, and disengagement from civic and political life. The trouble does not lie only with the emerging adults or their poor individual decisions but has muchdeeper roots in mainstream American culture--a culture which emerging adults have largely inherited rather than created. Older adults, Smith argues, must recognize that much of the responsibility for the pain and confusion young people face lies with them. Rejecting both sky-is-falling alarmism onthe one hand and complacent disregard on the other, Smith suggests the need for what he calls realistic concern--and a reconsideration of our cultural priorities and practices--that will help emerging adults more skillfully engage unique challenges they face.Even-handed, engagingly written, and based on comprehensive research, Lost in Transition brings much needed attention to the darker side of the transition to adulthood.

    This book presents a radically new answer, insisting that global society has only begun to realize its full potential. Author Howard Bloom argues that there’s a hidden mandate beneath the surface of capitalism: "It’s struggling to whisper and rumble its message to you and me. That hidden imperative can lift us from economic crisis, can make us a leader in the next-generation economy, and can dramatically upgrade our ability to empower our fellow human beings." Bloom sees crisis as opportunity, opportunity for the whole human race.In more than eighty short, fast chapters, insights appear suddenly, like the quick bursts of flashbulbs, taking the reader on a sweeping tour of human history, from the Stone Age to the present. Every chapter conveys a radically new way to see the astonishing mechanism we call "Western Civilization." Bloom marvels at how humans have turned toxic waste into food and fuel, trash into treasure, and garbage into gold. He shows how we've produced material miracles based on immaterial things—passion, persistence, and fantasy. He shows that what many regard as the end is just the beginning. The beginning of something you've never before imagined. The author explains why the secret to capitalism’s next great leap does not lie in new financial tricks, but in tapping things right under our noses in radically new ways—that is, tapping our imagination, our desire to feel useful, our desire to help others, and our desire to be recognized for contributing to the welfare of humanity. The key to next-generation capitalism lies in a big-picture view that's utterly unlike anything you've previously perceived. A big-picture view that will startle you. A big-picture view with which you can ignite the world, get a new handle on your life, and help transform society. This brilliant, inspirational work of daring ideas and breathtaking research offers more than hope. It offers unseen levels of understanding. Understanding that can literally redefine what it means to be a human being.From the Trade Paperback edition.

    This fast-moving narrative starts at ground zero, with the dramatic incubation of open-source software by Linux and its enigmatic creator, Linus Torvalds. With firsthand accounts, it describes how a motley group of programmers managed to shake up the computing universe and cause a radical shift in thinking for the post-Microsoft era. A powerful and engaging tale of innovation versus big business, Rebel Code chronicles the race to create and perfect open-source software, and provides the ideal perch from which to explore the changes that cyberculture has engendered in our society. Based on over fifty interviews with open-source protagonists such as Torvalds and open source guru Richard Stallman, Rebel Code captures the voice and the drama behind one of the most significant business trends in recent memory.

    In barely six years, a small group of young, ambitious programmers in Silicon Valley built an $11.5 billion business out of the ashes of a failed podcasting company. Today Twitter boasts more than 200 million active users and has affected business, politics, media, and other fields in innumerable ways. Now Nick Bilton of the New York Times takes readers behind the scenes with a narrative that shows what happened inside Twitter as it grew at exponential speeds. This is a tale of betrayed friendships and high-stakes power struggles as the four founders—Biz Stone, Evan Williams, Jack Dorsey, and Noah Glass—went from everyday engineers to wealthy celebrities, featured on magazine covers, Oprah, The Daily Show, and Time’s list of the world’s most influential people. Bilton’s exclusive access and exhaustive investigative reporting—drawing on hundreds of sources, documents, and internal e-mails—have enabled him to write an intimate portrait of fame, influence, and power. He also captures the zeitgeist and global influence of Twitter, which has been used to help overthrow governments in the Middle East and disrupt the very fabric of the way people communicate.

    Building these systems is complicated and, because few formally established patterns are available for designing them, most of these systems end up looking very unique. This practical guide shows you how to use existing software design patterns for designing and building reliable distributed applications.Although patterns such as those developed more than 20 years ago by the Gang of Four were largely restricted to running on single machines, author Brendan Burns--a Partner Architect in Microsoft Azure--demonstrates how you can reuse several of them in modern distributed applications.Systems engineers and application developers will learn how these patterns provide a common language and framework for dramatically increasing the quality of your system.

    At the height of its power, the Inca Empire stretched for more than one thousand miles down the Andes Mountains and the west coast of South America. It incorporated more than two hundred distinct ethnic groups and somewhere around fourteen million people were ruled by a much smaller number of Incas.Inca engineers designed and built an extensive and sophisticated system of roads and created buildings and walls from massive blocks of worked stone. Inca temples were opulent and featured the abundant use of gold, silver, and precious stones. Massive Inca armies won victory after victory as they steamrollered potential competitors. The Inca government controlled every aspect of the lives of its subjects, from the food that they ate to the clothes that they wore.By around 1500 CE, the Inca Empire had reached its greatest extent and looked set to persist for a very long time indeed. Instead, within little more than thirty years, it had been reduced to a small rump state, and within seventy years, it had vanished entirely. This is the story of the rapid rise and sudden fall of the mighty Inca Empire.

    Today’s "machine-learning" systems, trained by data, are so effective that we’ve invited them to see and hear for us?and to make decisions on our behalf. But alarm bells are ringing. Recent years have seen an eruption of concern as the field of machine learning advances. When the systems we attempt to teach will not, in the end, do what we want or what we expect, ethical and potentially existential risks emerge. Researchers call this the alignment problem.Systems cull résumés until, years later, we discover that they have inherent gender biases. Algorithms decide bail and parole?and appear to assess Black and White defendants differently. We can no longer assume that our mortgage application, or even our medical tests, will be seen by human eyes. And as autonomous vehicles share our streets, we are increasingly putting our lives in their hands.The mathematical and computational models driving these changes range in complexity from something that can fit on a spreadsheet to a complex system that might credibly be called “artificial intelligence.” They are steadily replacing both human judgment and explicitly programmed software.In best-selling author Brian Christian’s riveting account, we meet the alignment problem’s “first-responders,” and learn their ambitious plan to solve it before our hands are completely off the wheel. In a masterful blend of history and on-the ground reporting, Christian traces the explosive growth in the field of machine learning and surveys its current, sprawling frontier. Readers encounter a discipline finding its legs amid exhilarating and sometimes terrifying progress. Whether they—and we—succeed or fail in solving the alignment problem will be a defining human story.The Alignment Problem offers an unflinching reckoning with humanity’s biases and blind spots, our own unstated assumptions and often contradictory goals. A dazzlingly interdisciplinary work, it takes a hard look not only at our technology but at our culture—and finds a story by turns harrowing and hopeful.

    This offers the first broad treatment of the city in both its historic and its contemporary aspects.

    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.

    He traces AI's origins in ancient myth, through literary classics like Frankenstein, to today's sci-fi blockbusters, arguing that a fascination with AI is hardwired into the human psyche. He explains AI's history, technology, and potential; its manifestations in intelligent machines; its connections to neurology and consciousness, as well as—perhaps most tellingly—what AI reveals about us as human beings.In Our Own Image argues that we are on the brink of a fourth industrial revolution—poised to enter the age of Artificial Intelligence as science fiction becomes science fact. Ultimately, Zarkadakis observes, the fate of AI has profound implications for the future of science and humanity itself.
