“This is an amazing book . . . [Desmet is] one of the true geniuses I’ve spoken to . . . This book has really changed my view on a lot.”—Tucker Carlson “[Desmet] is waking a lot of people up to the dangerous place we are now with a brilliant distillation of how we ended up here.”—Robert F. Kennedy, Jr. The world continues to exist in the grips of mass formation—a dangerous, collective type of hypnosis—as we bear witness to loneliness, free-floating anxiety, and fear giving way to censorship, loss of privacy, and surrendered freedoms. It is all spurred by a singular, focused crisis narrative that forbids dissident views and relies on destructive groupthink. Desmet’s work on mass formation theory was brought to the world’s attention on The Joe Rogan Experience and in major alternative news outlets around the globe. Read this book—now in paperback, ebook, and audiobook—to get beyond the sound bites! Totalitarianism is not a coincidence and does not form in a vacuum. It arises from a collective psychosis that has followed a predictable script throughout history, its formation gaining strength and speed with each generation—from the Jacobins to the Nazis and Stalinists—as technology advances. Governments, mass media, and other mechanized forces use fear, loneliness, and isolation to demoralize populations and exert control, persuading large groups of people to act against their own interests, always with destructive results. In The Psychology of Totalitarianism, world-renowned Professor of Clinical Psychology Mattias Desmet deconstructs the societal conditions that allow this collective psychosis to take hold. By looking at our current situation and identifying the phenomenon of “mass formation”—a type of collective hypnosis—he clearly illustrates how close we are to surrendering to totalitarian regimes. With detailed analyses, examples, and results from years of research, Desmet lays out the steps that lead toward mass formation, including: * An overall sense of loneliness and lack of social connections and bonds * A lack of meaning—unsatisfying “bullsh*t jobs” that don’t offer purpose * Free-floating anxiety and discontent that arise from loneliness and lack of meaning * Manifestation of frustration and aggression from anxiety * Emergence of a consistent narrative from government officials, mass media, etc., that exploits and channels frustration and anxiety In addition to clear psychological analysis—and building on Hannah Arendt’s essential work on totalitarianism, The Origins of Totalitarianism—Desmet offers a sharp critique of the cultural groupthink that exists throughout society. He cautions against the dangers of our current cultural landscape, media consumption, and reliance on manipulative technologies and then offers simple solutions—both individual and collective—to prevent the willing sacrifice of our freedoms. “We can honor the right to freedom of expression and the right to self-determination without feeling threatened by each other,” Desmet writes. “But there is a point where we must stop losing ourselves in the crowd to experience meaning and connection. That is the point where the winter of totalitarianism gives way to a spring of life.” “One of the most important books I’ve ever read.”—Ivor Cummins, The Fat Emperor Podcast

A top cybersecurity journalist tells the story behind the virus that sabotaged Iran’s nuclear efforts and shows how its existence has ushered in a new age of warfare—one in which a digital attack can have the same destructive capability as a megaton bomb.  “Immensely enjoyable . . . Zetter turns a complicated and technical cyber story into an engrossing whodunit.”—The Washington Post   The virus now known as Stuxnet was unlike any other piece of malware built before: Rather than simply hijacking targeted computers or stealing information from them, it proved that a piece of code could escape the digital realm and wreak actual, physical destruction—in this case, on an Iranian nuclear facility.   In these pages, journalist Kim Zetter tells the whole story behind the world’s first cyberweapon, covering its genesis in the corridors of the White House and its effects in Iran—and telling the spectacular, unlikely tale of the security geeks who managed to unravel a top secret sabotage campaign years in the making.   But Countdown to Zero Day also ranges beyond Stuxnet itself, exploring the history of cyberwarfare and its future, showing us what might happen should our infrastructure be targeted by a Stuxnet-style attack, and ultimately, providing a portrait of a world at the edge of a new kind of war.

Praised by reviewers and practicing TCP/IP programmers alike, the TCP/IP Illustrated series examines the many facets of the TCP/IP protocol suite using a unique and highly-effective visual approach that describes the inner workings of TCP/IP with detail, insight, and clarity. Volume 3 provides detailed coverage of four essential topics with which today's TCP/IP programmers and network administrators must be thoroughly familiar: *T/TCP (TCP for Transactions), an extension to TCP that makes client-server transactions faster, more efficient, and more reliable; *HTTP (Hypertext Transfer Protocol), the foundation for the rapidly expanding World Wide Web; *NNTP (the Network News Transfer Protocol), the basis for the Usenet news system; and *UNIX Domain Protocols, a set of protocols used heavily in UNIX implementations. As in the previous two volumes, the book is filled with examples and implementation details within the 4.4BSD-Lite networking code. The TCP/IP Illustrated series provides a complete picture of the protocol suite that drives the Internet, and gives programmers, system administrators, and serious users the information, understanding, and skills they need to remain at the forefront of networking technology. 0201634953B04062001

Finally, programmers that need to truly understand the TCP/IP protocol suite have a resource to turn to, TCP/IP Illustrated. Instead of merely describing the RFC's, bestselling author Rich Stevens takes an innovative "visual" approach which, combined with his writing style, results in an accessible "understandable" guide to TCP/IP.
