From a Hackney council estate to the House of Lords, this is the extraordinary story of one of our greatest entrepreneurs. Alan Sugar was born in 1947 and brought up on a council estate in Clapton, in Hackney. As a kid he watched his dad struggle to support the family, never knowing from one week to the next if he'd have a job. It had a huge impact on him, fuelling a drive to succeed that was to earn him a sizeable personal fortune. Now he describes his amazing journey, from schoolboy enterprises like making and selling his own ginger beer to setting up his own company at nineteen; from Amstrad's groundbreaking ventures in hi-fi and computers, which made him the darling of the stock exchange, to the dark days when he nearly lost it all; from his pioneering deal with Rupert Murdoch to his boardroom battles at Tottenham Hotspur FC. He takes us into the world of The Apprentice, and describes his appointment as advisor to the government and elevation to the peerage. Like the man himself, this autobiography is forthright, funny and sometimes controversial.

From 1983 to 1986, the legendary physicist and teacher Richard Feynman gave a course at Caltech called “Potentialities and Limitations of Computing Machines.”Although the lectures are over ten years old, most of the material is timeless and presents a “Feynmanesque” overview of many standard and some not-so-standard topics in computer science. These include computability, Turing machines (or as Feynman said, “Mr. Turing's machines”), information theory, Shannon's Theorem, reversible computation, the thermodynamics of computation, the quantum limits to computation, and the physics of VLSI devices. Taken together, these lectures represent a unique exploration of the fundamental limitations of digital computers.Feynman's philosophy of learning and discovery comes through strongly in these lectures. He constantly points out the benefits of playing around with concepts and working out solutions to problems on your own-before looking at the back of the book for the answers. As Feynman says in the lectures: “If you keep proving stuff that others have done, getting confidence, increasing complexities of your solutions-for the fun of it-then one day you'll turn around and discovers that nobody actually did that one! And that's the way to become a computer scientist.”

"In 1950, mathematician-philosopher Norbert Wiener ended this classic book on the place of machines in society with a warning: "We shall never receive the right answers to our questions unless we ask the right questions.... The hour is very late, and the choice of good and evil knocks at our door." Wiener, the founder of the science of cybernetics--the study of the relationship between computers and the human nervous system--was widely mislabeled as an advocate for the automation of human life. As The Human Use for Human Beings reveals, his vision was much more complex and interesting, and is more relevant in today's world of AI than anyone could have anticipated. In his new introduction, Brian Christian aptly calls Wiener the "progenitor of contemporary AI-safety discourse." Wiener hoped that machines would release people from relentless and repetitive drudgery to achieve more creative pursuits, yet he anticipated the danger of dehumanizing and displacement. His pioneering views on the human-machine relationship as a "communicative process" are only more crucial now, as we carry in our pockets AI devices that we can literally speak to. His prescient warnings illuminate our contemporary relationships with language, art, and even social media. The Human Use of Human Beings examines the implications of cybernetics for education, law, language, science, technology, as Wiener anticipates the enormous impact--in effect, a third industrial revolution--that the computer has had on our lives."-- Provided by publisher

From the former news policy lead at Google, an urgent and groundbreaking account of the high-stakes global cyberwar brewing between Western democracies and the autocracies of China and Russia that could potentially crush democracy. From 2016 to 2020, Jacob Helberg led Google's global internal product policy efforts to combat disinformation and foreign interference. During this time, he found himself in the midst of what can only be described as a quickly escalating two-front technology cold war between democracy and autocracy. On the front-end, we're fighting to control the software--applications, news information, social media platforms, and more--of what we see on the screens of our computers, tablets, and phones, a clash which started out primarily with Russia but now increasingly includes China and Iran. Even more ominously, we're also engaged in a hidden back-end battle--largely with China--to control the Internet's hardware, which includes devices like cellular phones, satellites, fiber-optic cables, and 5G networks. This tech-fueled war will shape the world's balance of power for the coming century as autocracies exploit twenty-first-century methods to re-divide the world into twentieth century-style spheres of influence. Helberg cautions that the spoils of this fight are power over every meaningful aspect of our lives, including our economy, our infrastructure, our national security, and ultimately, our national sovereignty. Without a firm partnership with the government, Silicon Valley is unable to protect democracy from the autocrats looking to sabotage it from Beijing to Moscow and Tehran. The stakes of the ongoing cyberwar are no less than our nation's capacity to chart its own future, the freedom of our democratic allies, and even the ability of each of us to control our own fates, Helberg says. And time is quickly running out.

That's the promise, and peril, of the third digital revolution, where anyone will be able to make (almost) anything Two digital revolutions--computing and communication--have radically transformed our economy and lives. A third digital revolution is here: fabrication. Today's 3D printers are only the start of a trend, accelerating exponentially, to turn data into objects: Neil Gershenfeld and his collaborators ultimately aim to create a universal replicator straight out of Star Trek. While digital fabrication promises us self-sufficient cities and the ability to make (almost) anything, it could also lead to massive inequality. The first two digital revolutions caught most of the world flat-footed, thanks to Designing Reality that won't be true this time.

This introductory text covers the key areas of computer science, including recursive function theory, formal languages, and automata. It assumes a minimal background in formal mathematics. The book is divided into five parts: Computability, Grammars and Automata, Logic, Complexity, and Unsolvability. * Computability theory is introduced in a manner that makes maximum use of previous programming experience, including a "universal" program that takes up less than a page. * The number of exercises included has more than tripled. * Automata theory, computational logic, and complexity theory are presented in a flexible manner, and can be covered in a variety of different arrangements.

"As cyber-attacks dominate front-page news, as hackers displace terrorists on the list of global threats, and as top generals warn of a coming cyber war, few books are more timely and enlightening than Dark Territory: The Secret History of Cyber War, by Slate columnist and Pulitzer Prize-winning journalist Fred Kaplan. Kaplan probes the inner corridors of the National Security Agency, the beyond-top-secret cyber units in the Pentagon, the "information warfare" squads of the military services, and the national security debates in the White House, to tell this never-before-told story of the officers, policymakers, scientists, and spies who devised this new form of warfare and who have been planning--and (more often than people know) fighting--these wars for decades. From the 1991 Gulf War to conflicts in Haiti, Serbia, Syria, the former Soviet republics, Iraq, and Iran, where cyber warfare played a significant role, Dark Territory chronicles, in fascinating detail, a little-known past that shines an unsettling light on our future"--

This is about the nature of mathematical modelling, and the kinds of techniques that are useful for modelling. It is oriented towards simple efficient implementations on computers.

In 1983, Michael S. Dell, then an incoming freshman at the University of Texas at Austin, drove away from his parents' Houston home in a white BMW he'd bought selling subscriptions to his hometown newspaper. In the backseat were three personal computers. Today, he is the Chairman and Chief Executive Officer of Dell Computer Corporation, an $18 billion company, the second-largest manufacturer and marketer of computers in the world. Founded on a deceptively simple premise--to deliver high-performance computer systems directly to the end user--Dell Computer is the envy of its competition, constantly growing at five times the industry rate, and a perennial darling of Wall Street: its stock is up more than 36,000 percent this decade, and more than 200 percent in the last year. In Direct From Dell, Michael Dell himself tells the incredible story of Dell Computer's successful rise, beginning in his college dorm room with $1,000 in capital. In these pages, you'll see the formation of a great visionary--and a great company. You'll meet the young Dell who, at the tender age of eight, had already begun looking "to eliminate unnecessary steps" and who, as a numbers-loving adolescent, was inspired by a newfound fascination with computers to save his money to buy a coveted Apple II--only to promptly take it apart. You'll encounter a young visionary who, upon witnessing the inefficiencies of an exploding industry, challenged conventional wisdom and set out to do nothing less than beat IBM at its own game. In so doing, Dell forever changed the way things "had always been done" in the computer industry. You'll also see the birth of a Dell hallmark--the direct model--which, in its ability to reach the customer directly, eliminated not only a substantial middleman markup but also the possibility of costly excess inventory, setting the stage for other extraordinary achievements. In an industry notorious for its unreliable service, Dell utilized its direct customer relationships to pioneer the concept of customer "support"--and didn't rest until the caliber of its service was rivaled only by the quality of its products and its speed of delivery. But the story of Dell Computer is no fairy tale. Marked by uncharacteristically rapid growth, the company was faced with challenges that could have threatened its very existence. From forays into retail to under- (and over-) developed product lines, Dell learned some hard lessons along the way--and emerged stronger as a result. The strategies born of those times--unrivaled speed to market; superior customer service; a fierce commitment to producing constantly high-quality custom-made systems--heralded what has perhaps been the company's crowning achievement: an early exploitation of the Internet. One of the first companies to actually make money online, Dell is now selling more than $12 million worth of systems per day over www.dell.com. Not just for CEOs or those in high tech, the strategies revealed in Direct From Dell are invaluable to managers in a broad cross section of industries. From starting a successful business to pioneering computer sales and service over the Internet, Dell shares his perspectives on: Why it's infinitely better for any business starting out to have too little capital, rather than too much How studying your customers--not your competition--will give you a greater competitive edge Why it can be life-threatening to your company to pursue too many good ideas--or to grow too fast Why it's essential to run a P&L on every area of your business Why your people prose a greater threat to the health of your business than your competition does How you can exploit your competition's weakness by exposing its greatest strength How integrating your business virtually can make the difference between being quick--and being dead Revealing nothing less than a new model for doing business in the information age, Direct From Dell is both an extraordinary business success story and a manifesto for revolutionizing any industry.

"In The Second Self, Sherry Turkle looks at the computer not as a 'tool,' but as part of our social and psychological lives; she looks beyond how we use computer games and spreadsheets to explore how the computer affects our awareness of ourselves, of one another, and of our relationship with the world. 'Technology,' she writes, 'catalyzes changes not only in what we do but in how we think.' First published in 1984, The Second Self is still essential reading as a primer in the psychology of computation. This twentieth anniversary edition allows us to reconsider two decades of computer culture - to (re)experience what was and is most novel in our new media culture and to view our own contemporary relationship with technology with fresh eyes. Turkle frames this classic work with a new introduction, a new epilogue, and extensive notes added to the original text. Turkle talks to children, college students, engineers, AI scientists, hackers, and personal computer owners - people confronting machines that seem to think and at the same time suggest a new way for us to think - about human thought, emotion, memory, and understanding. Her interviews reveal that we experience computers as being on the border between inanimate and animate, as both an extension of the self and part of the external world. Their special place betwixt and between traditional categories is part of what makes them compelling and evocative. (In the introduction to this edition, Turkle quotes a PDA user as saying, 'When my Palm crashed, it was like a death. I thought I had lost my mind.') Why we think of the workings of a machine in psychological terms - how this happens, and what it means for all of us - is the ever more timely subject of The Second Self." -

"In The New Childhood, world-renowned global policy and education pioneer Jordan Shapiro provides a hopeful counterpoint to the fearful hand-wringing that has come to define our narrative around children and technology. Drawing on groundbreaking research in economics, psychology, philosophy and education, The New Childhood underscores how technology is guiding humanity toward a bright future in which children will be able to create new, better models of global citizenship, connection and community. Dividing the book into four sections: Self, Home, School and Society, Shapiro offers concrete, practical advice on how to parent and educate children effectively in a connected world and provides tools and techniques for using technology to engage with kids and help them learn and grow. He also draws on his own experience as a father of two sons, which helps bring the narrative to life. He compares the current moment to other great technological revolutions in humanity's past and presents entertaining micro-histories of cultural minutiae: the sandbox, finger painting, the family dinner and more. Most importantly, The New Childhood paints a timely, inspiring and positive picture of today's children, recognising that they are poised to create a progressive, diverse, meaningful and hyper-connected world that today's adults can only imagine. 'Timely, essential, and thought-provoking, The New Childhood is the must-read parenting guide for raising 21st century, digitally driven kids. Instead of raising a white flag and giving in to social media and the Internet, Jordan Shapiro tells parents how to embrace technology, stay involved in their children's lives, and prepare them for their future. Read it! I promise you'll rethink your parenting. I couldn't put it down.' - Michele Borba, EdD, author of UnSelfie: Why Empathetic Kids Succeed In Our All-About-Me World."--Publisher's description.

Over the past few decades there has been a revolution in terms of who controls knowledge and information. This rapid change has imperilled the way we think. Without pausing to consider the cost, the world has rushed to embrace the products and services of four titanic corporations. We shop with Amazon; socialise on Facebook; turn to Apple for entertainment; and rely on Google for information. These firms sell their efficiency and purport to make the world a better place, but what they have done instead is to enable an intoxicating level of daily convenience. As these companies have expanded, marketing themselves as champions of individuality and pluralism, their algorithms have pressed us into conformity and laid waste to privacy. They have produced an unstable and narrow culture of misinformation, and put us on a path to a world without private contemplation, autonomous thought, or solitary introspection - a world without mind. In order to restore our inner lives, we must avoid being co-opted by these gigantic companies, and understand the ideas that underpin their success. Elegantly tracing the intellectual history of computer science - from the Descartes and the enlightenment to Alan Turing to Stuart Brand and the hippie origins of today's Silicon Valley - Foer exposes the dark underpinnings of our most idealistic dreams for technology. The corporate ambitions of Google, Facebook, Apple, and Amazon, he argues, are trampling longstanding liberal values, especially intellectual property and privacy. This is a nascent stage in the total automation and homogenization of social, political, and intellectual life. By reclaiming our private authority over how we intellectually engage with the world, we have the power to stem the tide. At stake is nothing less than who we are, and what we will become. There have been monopolists in the past but today's corporate giants have far more nefarious aims. They're monopolists who want access to every facet of our identities and influence over every corner of our decision-making. Until now few have grasped the sheer scale of the threat. Foer explains not just the looming existential crisis but the imperative of resistance.

Major concepts are illustrated with running examples, and major algorithms are illustrated by Pascal computer programs. Chapter concludes with exercises and computer assignments. No prior knowledge of Gas or genetics is assumed.

In his too-short life, Aaron Swartz reshaped the Internet, questioned our assumptions about intellectual property, and touched all of us in ways that we may not even realize. His tragic suicide in 2013 at the age of twenty-six after being aggressively prosecuted for copyright infringement shocked the nation and the world. Here for the first time in print is revealed the quintessential Aaron Swartz: besides being a technical genius and a passionate activist, he was also an insightful, compelling, and cutting essayist. With a technical understanding of the Internet and of intellectual property law surpassing that of many seasoned professionals, he wrote thoughtfully and humorously about intellectual property, copyright, and the architecture of the Internet. He wrote as well about unexpected topics such as pop culture, politics both electoral and idealistic, dieting, and lifehacking. Including three in-depth and previously unpublished essays about education, governance, and cities, The Boy Who Could Change the World contains the life's work of one of the most original minds of our time.
