Enorm rigdom og magt er i dag koncentreret i nye markeder, hvor overvågning af og forudsigelser om vores adfærd bliver købt og solgt. Shoshana Zuboff betegner fænomenet overvågningskapitalisme og kalder det for en lige så stor omvæltning af den menneskelige tilværelse i dag, som den industrielle revolution var det i det 20. århundrede. Der er tale om en hidtil uset magtkonstellation karakteriseret ved ekstreme koncentrationer af viden uden demokratisk tilsyn – og prisen er vores frihed. Med begrænset modstand fra lovgivning og samfund truer overvågningskapitalismen vores nutid og vil dominere vores fremtid – hvis vi tillader det. Anmeldelser “Læs den – den er fremragende!” ★★★★★★ - Altinget ”Det hidtil mest ambitiøse forsøg på at tegne det store billede og forklare baggrunden for digitaliseringens følger, som vi oplever dem som individer og som samfundsborgere ... En fortsættelse af traditionen fra Adam Smith, Max Weber, Karl Polanyi og – tør man sige det – Karl Marx.” – The Observer ”En tilbundsgående researchet, fængende skrevet fortælling om overvågningskapitalismens opståen og dens skadelige virkninger for vores samfund... – New York Times Book Review ”... alle bør læse denne bog som et digitalt selvforsvar. Med stort klarsyn og moralsk mod demonstrerer Zuboff ikke alene, hvordan vores hjerner støvsuges for data, men også hvordan de ændres undervejs, hurtigt og radikalt.” – Naomi Klein, forfatter til Intet bliver som før og No Logo Om forfatteren Shoshana Zuboff er amerikansk socialpsykolog, filosof og professor emerita på Harvard Business School samt ekspert i den digitale revolution. Hun har udgivet en lang række bøger i spændingsfeltet mellem teknologi, psykologi, filosofi og økonomi, og i 1988 skrev hun The age of the Smart Machine: the Future of Work and Power, som blev et skelsættende hovedværk om computeriseringen af vores arbejde og liv.

A hack is any means of subverting a system's rules in unintended ways. The tax code isn't computer code, but a series of complex formulas. It has vulnerabilities; we call them "loopholes." We call exploits "tax avoidance strategies." And there is an entire industry of "black hat" hackers intent on finding exploitable loopholes in the tax code. We call them accountants and tax attorneys.In A Hacker's Mind, Bruce Schneier takes hacking out of the world of computing and uses it to analyse the systems that underpin our society: from tax laws to financial markets to politics. He reveals an array of powerful actors whose hacks bend our economic, political and legal systems to their advantage, at the expense of everyone else.Once you learn how to notice hacks, you'll start seeing them everywhere-and you'll never look at the world the same way again. Almost all systems have loopholes, and this is by design. Because if you can take advantage of them, the rules no longer apply to you.Unchecked, these hacks threaten to upend our financial markets, weaken our democracy and even affect the way we think. And when artificial intelligence starts thinking like a hacker-at inhuman speed and scale-the results could be catastrophic.But for those who would don the "white hat," we can understand the hacking mindset and rebuild our economic, political and legal systems to counter those who would exploit our society. And we can harness artificial intelligence to improve existing systems, predict and defend against hacks and realise a more equitable world.

THE NEW YORK TIMES BESTSELLER As seen on The Joe Rogan Experience!A groundbreaking dive into the role psychedelics have played in the origins of Western civilization, and a real-life quest for the Holy Grail.The most influential religious historian of the twentieth century, Huston Smith, once referred to it as the "best-kept secret" in history. Did the Ancient Greeks use drugs to find God? And did the earliest Christians inherit the same, secret tradition? A profound knowledge of visionary plants, herbs and fungi passed from one generation to the next, ever since the Stone Age?There is zero archaeological evidence for the original Eucharist - the sacred wine said to guarantee life after death for those who drink the blood of Jesus. The Holy Grail and its miraculous contents have never been found. In the absence of any hard data, whatever happened at the Last Supper remains an article of faith for today's 2.5 billion Christians. In an unprecedented search for real answers, The Immortality Key examines the archaic roots of the ritual that is performed every Sunday for nearly one third of the planet. Religion and science converge to paint a radical picture of Christianity's founding event...and, after centuries of debate, to solve history's greatest puzzle once and for all.Before the birth of Jesus, the Ancient Greeks found salvation in their own sacraments. Sacred beverages were routinely consumed as part of the so-called Ancient Mysteries - elaborate rites that led initiates to the brink of death. The best and brightest from Athens and Rome flocked to the spiritual capital of Eleusis, where a holy beer unleashed heavenly visions for two thousand years. Others drank the holy wine of Dionysus to become one with the god. In the 1970s, renegade scholars claimed this beer and wine - the original sacraments of Western civilization - were spiked with mind-altering drugs. In recent years, vindication for the disgraced theory has been quietly mounting in the laboratory. The constantly advancing fields of archaeobotany and archaeochemistry have hinted at the enduring use of hallucinogenic drinks in antiquity. And with a single dose of psilocybin, the psychopharmacologists at Johns Hopkins and NYU are now turning self-proclaimed atheists into instant believers. But the smoking gun remains elusive.If these sacraments survived for thousands of years in our remote prehistory, from the Stone Age to the Ancient Greeks, did they also survive into the age of Jesus? Was the Eucharist of the earliest Christians, in fact, a psychedelic Eucharist?With an unquenchable thirst for evidence, Brian C. Muraresku takes the reader on his twelve-year global hunt for proof. He tours the ruins of Greece with its government archaeologists. He gains access to the hidden collections of the Louvre Museum to show the continuity from pagan to Christian wine. He unravels the Ancient Greek of the New Testament with a Catholic priest. He spelunks into the catacombs under the streets of Rome to decipher the lost symbols of Christianity's oldest monuments. He breaches the secret archives of the Vatican to unearth manuscripts never before translated into English. And with leads from the archaeological chemists at the University of Pennsylvania and the Massachusetts Institute of Technology, he unveils the first scientific data for the ritual use of psychedelic drugs in classical antiquity.The Immortality Key reconstructs the suppressed history of women consecrating a forbidden, drugged Eucharist that was later banned by the Church Fathers. Women who were then targeted as witches during the Inquisition, when Europe's sacred pharmacology largely disappeared. Have the scientists of today resurrected this lost technology? Is Christianity capable of returning to its roots?Featuring a Foreword by Graham Hancock, the New York Times bestselling author of America Before: The Key to Earth's Lost Civilization.

Spyware – programmer, der udspionerer din gøren og laden på pc’en, og som f.eks. sender dine indtastede kreditkortoplysninger videre til en bagmand. Keyloggere – programmer der registrerer alt, hvad du taster på tastaturet, og sender det til en bagmand. Zombier – din pc kan blive overtaget af en bagmand og skjult indlemmet i et netværk (botnet) af andre zombie-computere, som sammen angriber hjemmesider eller sender store mængder spam ud i verden. Adware – programmer, der viser reklamer på din pc og på hjemmesider, og som er meget irriterende. Ransomware – du kan blive afkrævet en løsesum for at slippe din pc fri for malware, der krypterer dine filer, så du ikke kan læse dem igen. Du lærer om: Identitetstyveri – pas på ikke at få stjålet dine personlige oplysninger, som kriminelle så kan misbruge. Fupbutikker – lær at spotte falske netbutikker, som sælger kopivarer under dække af at være ægte eller sælger dine kreditkortoplysninger.

Copyright is everywhere. Your smartphone incorporates thousands of items of intellectual property. Someone owns the reproduction rights to photographs of your dining table. At this very moment, battles are raging over copyright in the output of artificial intelligence programs. Not only books but wallpaper, computer programs and cuddly toys are now deemed to be intellectual properties - making copyright a labyrinthine construction of laws covering almost all products of human creativity.Copyright has its roots in eighteenth-century London, where it was first established to limit printers' control of books. Principled arguments against copyright arose from the start and nearly abolished it in the nineteenth century. But a handful of little-noticed changes in the late twentieth century concentrated ownership of immaterial goods into very few hands.Who Owns This Sentence? is an often-humorous and always-enlightening cultural, legal, and global history of the idea that intangible things can be owned, and makes a persuasive case for seeing copyright as an engine of inequality in the twenty-first century.

A broad introduction to cryptography—what it is, how it really works, what its future holds, and why every informed citizen should understand its basics.We all keep secrets—from our gym locker codes to our email passwords to our online interactions. And we choose to share those secrets only with those whom we trust. So, too, do organizations, businesses, governments, and armies. In this fascinating book Cryptography, Panos Louridas provides a broad and accessible introduction to cryptography, the art and science of keeping and revealing secrets. Louridas explains just how cryptography works to keep our communications confidential, tracing it back all the way to its ancient roots. Then he follows its long and winding path to where we are today and reads the signs that point to where it may go tomorrow.A few years back, interest in cryptography was restricted to specialists. Today, as we all live our lives attuned to our digital footprint and the privacy issues it entails, it becomes more and more essential to have a basic understanding of cryptography and its applications to everyday life. Starting with classical cryptography, Cryptography takes the reader all the way up to the twenty-first century cryptographic applications that underpin our lives in the digital realm. Along the way, Louridas also explains concepts such as symmetric cryptography, asymmetric cryptography, cryptographic protocols and applications, and finally, quantum and post-Quantum cryptography as well as the links between cryptography and computer security.
