    Acclaimed information-security expert and author of Mastering Bitcoin, Andreas M. Antonopoulos examines and contextualizes the significance of bitcoin through a series of essays spanning the exhilarating maturation of this technology. Bitcoin, a technological breakthrough quietly introduced to the world in 2008, is transforming much more than finance. Bitcoin is disrupting antiquated industries to bring financial independence to billions worldwide. In this book, Andreas explains why bitcoin is a financial and technological evolution with potential far exceeding the label “digital currency.” Andreas goes beyond exploring the technical functioning of the bitcoin network by illuminating bitcoin’s philosophical, social, and historical implications. As the internet has essentially transformed how people around the world interact and has permanently impacted our lives in ways we never could have imagined, bitcoin -- the internet of money -- is fundamentally changing our approach to solving social, political, and economic problems through decentralized technology.

    When their phone is out of sight or the signal wavers, anxiety rises. You hear people saying again and again: 'I can't live without my phone, ' and sadly technology which should be a wonderful boon to us has started to blight lives; the more you are addicted, the less you get out of it. Technology can turn against us if we let it. Allen Carr's Easyway is the most successful stop-smoking method of all time. It works by unravelling the brainwashing that leads us to desire the very thing that is bad for us and it can help beat any addiction. For the first time, it has been applied to the problems of overusing your mobile phone, and it works

    Why did work become so miserable? Who is responsible? And does any company have a model for doing it right?For two years, Lyons ventured in search of answers. From the innovation-crazed headquarters of the Ford Motor Company in Detroit, to a cult-like "Holocracy" workshop in San Francisco, and to corporate trainers who specialize in ... Legos, Lyons immersed himself in the often half-baked and frequently lucrative world of what passes for management science today. He shows how new tools, workplace practices, and business models championed by tech's empathy-impaired power brokers have shattered the social contract that once existed between companies and their employees. These dystopian beliefs--often masked by pithy slogans like "We're a Team, Not a Family"--have dire consequences: millions of workers who are subject to constant change, dehumanizing technologies--even health risks. A few companies, however, get it right. With Lab Rats, Lyons makes a passionate plea for business leaders to understand this dangerous transformation, showing how profit and happy employees can indeed coexist.

    More and more often, those companies look to technology consultants to fulfill their needs. There are real advantages to being a consultant. You make contacts with a lot of different people; you get exposure to many industries; and most important, unlike a software developer in the IT department for a brick-and-mortar company, as a technology consultant, you are the profit center…so long as you are billing.

    With a blend of software engineering facts and thought-provoking opinions, Fred Brooks offers insight for anyone managing complex projects. These essays draw from his experience as project manager for the IBM System/360 computer family and then for OS/360, its massive software system. Now, 45 years after the initial publication of his book, Brooks has revisited his original ideas and added new thoughts and advice, both for readers already familiar with his work and for readers discovering it for the first time.The added chapters contain (1) a crisp condensation of all the propositions asserted in the original book, including Brooks' central argument in The Mythical Man-Month: that large programming projects suffer management problems different from small ones due to the division of labor; that the conceptual integrity of the product is therefore critical; and that it is difficult but possible to achieve this unity; (2) Brooks' view of these propositions a generation later; (3) a reprint of his classic 1986 paper "No Silver Bullet"; and (4) today's thoughts on the 1986 assertion, "There will be no silver bullet within ten years."

    This is necessary because, in the words of Michael Polanyi, "we can know more than we can tell." Our design choices are not the result of an ineluctable chain of logic; they come from a deeper place, one which is visceral and inarticulate.Polanyi calls this "tacit knowledge", a thing which we only understand as part of something else. When we speak, we do not focus on making sounds, we focus on our words. We understand the muscular act of speech, but would struggle to explain it.To write software, we must learn where to draw boundaries. Good software is built through effective indirection. We seem to have decided that this skill can only be learned through practice; it cannot be taught, except by example. Our decisions may improve with time, but not our ability to explain them. It's true that the study of these questions cannot yield a closed-form solution for judging software design. We can make our software simple, but we cannot do the same to its problem domain, its users, or the physical world. Our tacit knowledge of this environment will always inform our designs.This doesn't mean that we can simply ignore our design process. Polanyi tells us that tacit knowledge only suffices until we fail, and the software industry is awash with failure. Our designs may never be provably correct, but we can give voice to the intuition that shaped them. Our process may always be visceral, but it doesn't have to be inarticulate.And so this book does not offer knowledge, it offers clarity. It is aimed at readers who know Clojure, but struggle to articulate the rationale of their designs to themselves and others. Readers who use other languages, but have a passing familiarity with Clojure, may also find this book useful.

    Targeting American utility companies, NATO, and electric grids in Eastern Europe, the strikes became ever more brazen, eventually leading to the first-ever blackouts triggered by hackers. They culminated in the summer of 2017 when malware known as NotPetya was unleashed, compromising, disrupting, and paralyzing some of the world's largest companies. At the attack's epicenter in Ukraine, ATMs froze. The railway and postal systems shut down. NotPetya spread around the world, inflicting an unprecedented ten billions of dollars in damage--the largest, most penetrating cyberattack the world had ever seen.The hackers behind these attacks are quickly gaining a reputation as the most dangerous team of cyberwarriors in the internet's history: Sandworm. Believed to be working in the service of Russia's military intelligence agency, they represent a persistent, highly skilled, state-sponsored hacking force, one whose talents are matched by their willingness to launch broad, unrestrained attacks on the most critical infrastructure of their adversaries. They target government and private sector, military and civilians alike.From WIRED senior writer Andy Greenberg comes Sandworm, the true story of the desperate hunt to identify and track those attackers. It considers the danger this force poses to our national stability and security. And as the Kremlin's role in manipulating foreign governments and sparking chaos globally comes into greater focus, Sandworm reveals the realities not just of Russia's global digital offensive, but of an era where warfare ceases to be waged on the battlefield--where the line between digital and physical conflict begins to blur, with world-shaking implications.

    If you're a reasonably proficient programmer who can think logically, you have all the background you'll need. Stepanov and Rose introduce the relevant abstract algebra and number theory with exceptional clarity. They carefully explain the problems mathematicians first needed to solve, and then show how these mathematical solutions translate to generic programming and the creation of more effective and elegant code. To demonstrate the crucial role these mathematical principles play in many modern applications, the authors show how to use these results and generalized algorithms to implement a real-world public-key cryptosystem. As you read this book, you'll master the thought processes necessary for effective programming and learn how to generalize narrowly conceived algorithms to widen their usefulness without losing efficiency. You'll also gain deep insight into the value of mathematics to programming--insight that will prove invaluable no matter what programming languages and paradigms you use. You will learn aboutHow to generalize a four thousand-year-old algorithm, demonstrating indispensable lessons about clarity and efficiencyAncient paradoxes, beautiful theorems, and the productive tension between continuous and discreteA simple algorithm for finding greatest common divisor (GCD) and modern abstractions that build on itPowerful mathematical approaches to abstractionHow abstract algebra provides the idea at the heart of generic programmingAxioms, proofs, theories, and models: using mathematical techniques to organize knowledge about your algorithms and data structuresSurprising subtleties of simple programming tasks and what you can learn from themHow practical implementations can exploit theoretical knowledge

    That was before one pioneering work documented the underground computer revolution that was about to change our world forever. With groundbreaking profiles of Bill Gates, Steve Wozniak, MIT's Tech Model Railroad Club, and more, Steven Levy's Hackers brilliantly captured a seminal moment when the risk-takers and explorers were poised to conquer twentieth-century America's last great frontier. And in the Internet age, the hacker ethic-first espoused here-is alive and well.
