Computer Information Technology

Behind the familiar surfaces of the telephone, radio, and television lies a sophisticated and intriguing body of knowledge known as information theory. This is the theory that has permitted the rapid development of all sorts of communication, from color television to the clear transmission of photographs from the vicinity of Jupiter. Even more revolutionary progress is expected in the future.

Les histoires nous ont réunis. Les livres ont diffusé nos idées et nos mythologies. Internet nous a promis le savoir infini. Les algorithmes ont découvert nos secrets – et nous ont divisés. Quel monde nous promet l’IA ? Depuis cent mille ans, nous, les Sapiens, avons acquis un gigantesque pouvoir. Mais malgré nos découvertes, inventions et conquêtes, nous sommes aujourd’hui confrontés à une crise existentielle inédite. Le monde est au bord de l’effondrement écologique. Les tensions politiques se multiplient. La désinformation abonde.

This book is a consolidation of 16+ years of experience, knowledge, and tips gathered while working in the Information Technology Industry.

When "metadata" became breaking news, appearing in stories about surveillance by the National Security Agency, many members of the public encountered this once-obscure term from information science for the first time. Should people be reassured that the NSA was "only" collecting metadata about phone calls - information about the caller, the recipient, the time, the duration, the location - and not recordings of the conversations themselves? Or does phone call metadata reveal more than it seems?

If you buy a book at the bookstore, you own it. You can take it home, scribble in the margins, put it on the shelf, lend it to a friend, or sell it at a garage sale. But is the same thing true for the eBooks or other digital goods you buy? Retailers and copyright holders argue that you don't own those purchases, you merely license them. That means your eBook vendor can delete the book from your device without warning or explanation - as Amazon deleted Orwell's 1984 from the Kindles of surprised readers.

James Gleick, the author of the best sellers Chaos and Genius, now brings us a work just as astonishing and masterly: A revelatory chronicle and meditation that shows how information has become the modern era’s defining quality - the blood, the fuel, the vital principle of our world. The story of information begins in a time profoundly unlike our own, when every thought and utterance vanishes as soon as it is born.

El esperado nuevo libro de Yuval Noah Harari, uno de los pensadores más innovadores, interesantes y clarividentes de la actualidad, y autor de Sapiens, el fenómeno literario global que ha cautivado a millones de lectores. En Nexus, Harari contempla a la humanidad desde la amplia perspectiva de la historia para analizar cómo las redes de información han hecho y deshecho nuestro mundo. Durante los últimos 100.000 años, los sapiens hemos acumulado un enorme poder.

Each of us has an ever-growing collection of personal digital data: documents, photographs, PowerPoint presentations, videos, music, emails, and texts sent and received. To access any of this, we have to find it. The ease (or difficulty) of finding something depends on how we organize our digital stuff.

People are now exposed to more information than ever before, provided both by technology and by increasing access to every level of education. These societal gains, however, have also helped fuel a surge in narcissistic and misguided intellectual egalitarianism that has crippled informed debates on any number of issues. Today, everyone knows everything and all voices demand to be taken with equal seriousness, and any claim to the contrary is dismissed as undemocratic elitism.

Andrew J. Stewart convincingly shows that emergency software patches and new security products cannot provide the solution to threats such as computer hacking, viruses, software vulnerabilities, and electronic spying. Profound underlying structural problems must first be understood, confronted, and then addressed.

"Big Data" is on the covers of Science, Nature, The Economist, and Wired magazines, on the front pages of the Wall Street Journal and The New York Times. But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure.

We live in the age of disinformation - of organized deception. Spy agencies pour vast resources into hacking, leaking, and forging data, often with the goal of weakening the very foundation of liberal democracy: trust in facts. Thomas Rid, a renowned expert on technology and national security, was one of the first to sound the alarm, even before the 2016 election. But this is not new. The story of modern disinformation begins with the clash between communism and capitalism after the Russian Revolution.

Our data is besieged daily in the information economy, leading to hidden AI harms. Companies can do this because our laws are built on outdated ideas that trap lawmakers, regulators, and courts into wrong assumptions, resulting in ineffective approaches to one of the most pressing concerns of our generation. Drawing on behavioral science, social data science, and economics, this book dispels enduring misconceptions about AI-driven interactions. Its exploration offers a view of why current regulations fail to protect us against digital harms, particularly those created by AI.

It’s a signal paradox of our times that we live in an information society but do not know how it works. And without understanding how our information is stored, used, and protected, we are vulnerable to having it exploited. In Fancy Bear Goes Phishing, Scott J. Shapiro draws on his popular Yale University class about hacking to expose the secrets of the digital age. With lucidity and wit, he establishes that cybercrime has less to do with defective programming than with the faulty wiring of our psyches and society.

The NIST Cybersecurity Framework, intelligently designed to synchronize with top-tier industry practices, is a treasure trove for all cybersecurity enthusiasts, IT professionals, or organizational leaders determined to enhance their information systems security. This book, with its ability to translate complex concepts into accessible lessons, has the power to elevate beginners into adept cybersecurity practitioners.

Once the unrivaled titan of social media, Facebook held a singular place in culture and politics. Along with its sister platforms Instagram and WhatsApp, it was a daily destination for billions of users around the world. Inside and outside the company, Facebook extolled its products as bringing people closer together and giving them voice. But in the wake of the 2016 election, even some of the company’s own senior executives came to consider those claims pollyannaish and simplistic.

For a physicist, all the world is information. The universe and its workings are the ebb and flow of information. We are all transient patterns of information, passing on the recipe for our basic forms to future generations using a four-letter digital code called DNA. In this engaging and mind-stretching account, Vlatko Vedral considers some of the deepest questions about the universe and considers the implications of interpreting it in terms of information.

Claude Shannon was a tinkerer, a playful wunderkind, a groundbreaking polymath, and a digital pioneer whose insights made the Information Age possible. He constructed fire-breathing trumpets and customized unicycles, outfoxed Vegas casinos, and built juggling robots, but he also wrote the seminal text of the Digital Revolution. That work allowed scientists to measure and manipulate information as objectively as any physical object. His work gave mathematicians and engineers the tools to bring that world to pass.
