A simple web search picks out a handful of relevant needles from the world's biggest haystack: the billions of pages on the World Wide Web. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers; and we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? This is the first book to answer that question in language anyone can understand, revealing the extraordinary ideas that power our PCs, laptops, and smartphones. Using vivid examples, John MacCormick explains the fundamental "tricks" behind nine types of computer algorithms, including artificial intelligence (where we learn about the "nearest neighbor trick" and "twenty questions trick"), Google's famous PageRank algorithm (which uses the "random surfer trick"), data compression, error correction, and much more. These revolutionary algorithms have changed our world: this book unlocks their secrets, and lays bare the incredible ideas that our computers use every day.

    Police: A Field Guide is an illustrated handbook to the methods, mythologies, and history that animate today’s police. It is a survival manual for encounters with cops and police logic, whether it arrives in the shape of "officer friendly", "Tasers", "curfews", "non-compliance", or reformist discourses about so-called "bad apples". In a series of short chapters, each focusing on a single term, such as the "beat", "order", "badge", "throw-down weapon", and much more, authors David Correia and Tyler Wall present a guide that reinvents and demystifies the language of policing in order to better prepare activists—and anyone with an open mind—on one of the key issues of our time: police brutality. In doing so, they begin to chart a future free of this violence—and of police.

    . . a lively, engaging masterpiece."--Erik Brynjolfsson, bestselling co-author of The Second Machine AgeMIT professor Sinan Aral isn't only one of the world's leading experts on social media--he's also an entrepreneur and investor, giving him an unparalleled 360-degree view of the technology's great promise as well as its outsize capacity to damage our politics, our economy, and even our personal health.Drawing on two decades of his own research and business experience, Aral goes under the hood of the biggest, most powerful social networks to tackle the critical question of just how much social media actually shapes our choices, for better or worse. Aral shows how the tech behind social media offers the same set of behavior-influencing levers to both Russian hackers and brand marketers--to everyone who hopes to change the way we think and act--which is why its consequences affect everything from elections to business, dating to health. Along the way, he covers a wide array of topics, including how network effects fuel Twitter's and Facebook's massive growth to the neuroscience of how social media affects our brains, the real consequences of fake news, the power of social ratings, and the impact of social media on our kids.In mapping out strategies for being more thoughtful consumers of social media, The Hype Machine offers the definitive guide to understanding and harnessing for good the technology that has redefined our world overnight.

    Norbert Wiener's classic is one in that small company. Founder of the science of cybernetics—the study of the relationship between computers and the human nervous system—Wiener was widely misunderstood as one who advocated the automation of human life. As this book reveals, his vision was much more complex and interesting. He hoped that machines would release people from relentless and repetitive drudgery in order to achieve more creative pursuits. At the same time he realized the danger of dehumanizing and displacement. His book examines the implications of cybernetics for education, law, language, science, technology, as he anticipates the enormous impact—in effect, a third industrial revolution—that the computer has had on our lives.
