    Today, Data is the vital raw material of the information economy. The explosive abundance of this digital asset, more than doubling every two years, is creating a new world of opportunity and challenge.Data-ism is about this next phase, in which vast, Internet-scale data sets are used for discovery and prediction in virtually every field. It is a journey across this emerging world with people, illuminating narrative examples, and insights. It shows that, if exploited, this new revolution will change the way decisions are made—relying more on data and analysis, and less on intuition and experience—and transform the nature of leadership and management.Lohr explains how individuals and institutions will need to exploit, protect, and manage their data to stay competitive in the coming years. Filled with rich examples and anecdotes of the various ways in which the rise of Big Data is affecting everyday life it raises provocative questions about policy and practice that have wide implications for all of our lives.

    Darrell Huff runs the gamut of every popularly used type of statistic, probes such things as the sample study, the tabulation method, the interview technique, or the way the results are derived from the figures, and points up the countless number of dodges which are used to fool rather than to inform.

    What hope do we have against superintelligent machines? But we aren't really on the path to developing intelligent machines. In fact, we don't even know where that path might be.A tech entrepreneur and pioneering research scientist working at the forefront of natural language processing, Erik Larson takes us on a tour of the landscape of AI to show how far we are from superintelligence, and what it would take to get there. Ever since Alan Turing, AI enthusiasts have equated artificial intelligence with human intelligence. This is a profound mistake. AI works on inductive reasoning, crunching data sets to predict outcomes. But humans don't correlate data sets: we make conjectures informed by context and experience. Human intelligence is a web of best guesses, given what we know about the world. We haven't a clue how to program this kind of intuitive reasoning, known as abduction. Yet it is the heart of common sense. That's why Alexa can't understand what you are asking, and why AI can only take us so far.Larson argues that AI hype is both bad science and bad for science. A culture of invention thrives on exploring unknowns, not overselling existing methods. Inductive AI will continue to improve at narrow tasks, but if we want to make real progress, we will need to start by more fully appreciating the only true intelligence we know--our own.

    Arguing that the processes creating the technium are akin to those of biological evolution, Kelly devotes the opening sections of his exposition to that analogy, maintaining that the technium exhibits a similar tendency toward self-organizing complexity. Having defined the technium, Kelly addresses its discontents, as expressed by the Unabomber (although Kelly admits to trepidation in taking seriously the antitechnology screeds of a murderer) and then as lived by the allegedly technophobic Amish. From his observations and discussions with some Amish people, Kelly extracts some precepts of their attitudes toward gadgets, suggesting folk in the secular world can benefit from the Amish approach of treating tools as servants of self and society rather than as out-of-control masters. Exploring ramifications of technology on human welfare and achievement, Kelly arrives at an optimistic outlook that will interest many, coming, as it does, from the former editor of Wired magazine."Gilbert Taylor, Booklist

    . . But in fact, your data is your best defense against coercive marketing and intrusive government practices. Your data is nothing less than a superpower waiting to be harnessed.” —FROM THE INTRODUCTION In the past, the future was opaque—the territory of fortune-tellers, gurus, and dubious local TV weathermen. But thanks to recent advances in computing and the reams of data we create through smartphone and Internet use, prediction models for individual behavior grow smarter and more sophisticated by the day. Whom you should marry, whether you’ll commit a crime or fall victim to one, if you’ll contract a specific strain of flu—even your precise location at any given moment years into the future—are becoming easily accessible facts. The naked future is upon us, and the implications are staggering.Patrick Tucker draws on stories from health care to urban planning to online dating to reveal the shape of a future that’s ever more certain. In these pages you’ll meet scientists and inventors who can predict your behavior based on your friends’ Twitter updates. They are also hacking the New York City sewer system to predict environmental conditions, anticipating how much the weather a year from now will cost an individual farmer, figuring out the time of day you’re most likely to slip back into a bad habit, and guessing how well you’ll do on a test before you take it. You’ll learn how social networks like Facebook are using your data to turn you into an advertisement and why the winning formula for a blockbuster movie is more predictable than ever.The rise of big data and predictive analytics means that governments and corporations are becoming much more effective at accomplishing their goals and at much less cost. Tucker knows that’s not always a good thing. But he also shows how we’ve gained tremendous benefits that we have yet to fully realize.Thanks to the increased power of predictive science, we’ll be better able to stay healthy, invest our savings more wisely, learn faster and more efficiently, buy a house in the right neighborhood at the right time, avoid crime, thwart terrorists, and mitigate the consequences of natural disasters. What happens in a future that anticipates your every move? The surprising answer: we’ll live better as a result.

    He is also the winner of more National Coach of the Year awards than any other college coach. Garrido’s former teams at Cal State Fullerton and, more recently, at the University of Texas together have compiled a total of five College World Series championships under his leadership. But despite his unmatched record as a winner, Coach Garrido is not a win-at-all-costs coach. He teaches his players to focus on developing character, being good teammates, mastering all facets of the game, and playing with joy in the moment rather than focusing on the scoreboard. Augie teaches that the challenges faced in the batter’s box or on the pitcher’s mound are universal—and that the lessons learned on the diamond are applicable off the field, too. Life Is Yours to Win follows the coach’s journey of self-discovery and his evolution from being driven by fear to being motivated by passion. His unique and compelling book offers this revered leader’s philosophy on life and his thoughtful approach to helping young men understand both who they are and how they can be successful in their work, their relationships, and their communities. Every individual will find advice worth following including: •BE A PLAYER, NOT A PROSPECT—If you want to be considered a star in your field, whatever that may be, you need to be fully engaged. Augie once had his Labrador retriever demonstrate the joy of play to a team that needed a reminder of why they loved baseball as children. •STEP UP, SUPERMAN—Augie stages a costumed Superhero Scrimmage each Halloween to remind his players that their inner superhero is just waiting for the perfect moment when preparation meets opportunity, potential is fulfilled, and destiny is realized. •THE FEARLESS FIELD—To be successful in the often cruel game of baseball, players must master fear and other emotions so they are energized rather than paralyzed. Augie once rented a hearse and placed a casket on the pitcher’s mound to help a slumping Cal State Fullerton team bury their fears and put losses behind them. •BUDDHA AT BAT—Bunting and other “small ball” skills are not as glorified as home runs and big plays, but Coach Garrido’s teams are known for putting players in scoring position and winning games by following a Zen-like philosophy of claiming small victories during each at bat, in each inning that add up to winning records. Augie’s coaching methods are unconventional, but his creativity and wry humor provide masterful life lessons. His insights will help you both on and off the field by providing fresh approaches to conquering fears, living with joy and passion in each moment, establishing personal principles, and appreciating the value of both losing and winning. This is a book by a beloved college coach but it is packed with Major League insights and anecdotes featuring many of baseball’s greatest players and most inspiring spirits. Life Is Yours to Win will appeal to anyone who appreciates the wisdom of a proven winner in sports and in life.

    Then, in one fateful night, she lost everything, and the nightmare beganJennifer Robertson was working hard to build a life for herself from the ashes of her first marriage. Still only twenty-six, she swiped right on a dating app and met Gerry Cotten, a man she would not normally have considered—too young and not her type—but found she’d met her match. Eccentric but funny and kind, Cotten turned out to be a bitcoin wizard who quickly amassed substantial wealth through his company, Quadriga. The couple travelled the world, first-class all the way, while Cotten worked on his multitude of encrypted laptops. Then, while the couple was on their honeymoon in India, opening an orphanage in their name, Gerry fell ill and died in a matter of hours. Jennifer was consumed by grief and guilt, but that was only the beginning. It turned out that Gerry owed $250 million to Quadriga customers, and all the passwords to his encrypted virtual vaults, hidden on his many laptops, had died with him. Jennifer was left with more than one hundred thousand investors looking for their money, and questions, suspicions and accusations spiralling dangerously out of control. The Quadriga scandal touched off major investment and criminal investigations, not to mention Internet rumours circulating on dark message boards, including claims that Gerry had faked his own death and that his wife was the real mastermind behind a sophisticated sting operation. While Jennifer waited for a dead man’s switch e-mail that would probably never come, it became clear that Cotten had gambled away about $100 million of the funds entrusted to him for investment in his many schemes, leaving Robertson holding the bag. Bitcoin Widow is Catch Me If You Can meeting a widow betrayed, a life of fairy-tale romance and private jets torched by duplicity, as Jennifer Robertson tries to reset her life in the wake of one of the biggest investments scandals of the digital age.

After a deep dive into modern logic, including an introduction to linear logic and the logic-savvy Prolog language, the trip concludes with a tour of modern set theory and the advances and paradoxes of modern mechanical computing.If your high school or college math courses left you grasping for the inner meaning behind the numbers, Mark’s book will both entertain and enlighten you.

    More then seven thousand robotic systems are now in Iraq. Pilots in Nevada are remotely killing terrorists in Afghanistan. Scientists are debating just how smart - and how lethal - to make their current robotic prototypes. And many of the most renowned science fiction authors are secretly consulting for the Pentagon on the next generation.Blending historic evidence with interviews from the field, Singer vividly shows that as these technologies multiply, they will have profound effects on the front lines as well as on the politics back home. Moving humans off the battlefield makes wars easier to start, but more complex to fight. Replacing men with machines may save some lives, but will lower the morale and psychological barriers to killing. The "warrior ethos", which has long defined soldiers' identity, will erode, as will the laws of war that have governed military conflict for generations.While his analysis is unnerving, there's an irresistible gee-whiz quality to the innovations Singer uncovers. Wired for War travels from Iraq to see these robots in combat to the latter-day "skunk works" in America's suburbia, where tomorrow's technologies of war are quietly being designed. In Singer's hands, the future of war is as fascinating as it is frightening.
