Do you think you know something about Bitcoin and Austrian Economics? If so you may be ready for Cryptoeconomics. This is not a work for the uninitiated. The content is dense – it does not repeat itself. It is not a contribution to the echo chamber, will not show you how to set up a wallet, the future price, or what to do. Cryptoeconomics applies rational economic principles to Bitcoin, demonstrating flaws and unnecessary complexities in them, and in common understandings of Bitcoin. It will improve your understanding of both. Bitcoin requires a new, rigorous, and comprehensive discipline. This is it. Bitcoin is something new. It seems to defy understanding. Has there ever been a fixed supply money? Is there another case of production cost varying directly with product price? Is there anything else with a competitive yet fixed rate of transactability? To see past the hype, understand the value proposition, security model, and economic behavior, this may be your only source. Bitcoin is economics, technology, and security. Without incorporating all of these aspects, errors will be made. Economists, technologists, security experts, and even numerologists have attempted to explain it. Each brings a limited perspective, failing to incorporate essential aspects. The author found himself uniquely qualified to integrate them. His work in Bitcoin began with a hardware wallet. He spent a year analyzing threats, working with electronics design, hardware exploitation, and state surveillance experts. He chose the Libbitcoin software library, as Satoshi’s prototype was not factored for development and was largely financed by the Bitcoin Foundation, a corporate consortium. He later dedicated himself to Libbitcoin, eventually writing or editing all of its ~500,000 lines of code. Few have comparable experience with such a comprehensive Bitcoin stack. As a combat-experienced fighter pilot in the U.S. Navy he experienced state threats. He became a highly-qualified Strike Fighter Tactics Instructor, in which his primary role was tactics analysis and threat presentation. He also advised for the Navy on the Strike Fighter Training System network, Joint Strike Fighter, early GPS weapons, and F/A-18 systems. His understanding of the physical nature of all security was enhanced by decades of training in Japanese martial arts, achieving black belt rankings in five disciplines. His degree and experience in computer science mixed with extensive business experience, founding several companies. He has worked at IBM and as a Principle Architect at Microsoft, two of the world’s largest companies. The latter purchased his first startup, and his second was acquired by Veritas Capital. He was awarded three related U.S. patents. Eventually he became an angel investor, sharing his experience with other entrepreneurs. As CTO of his first company he published three computer security advisories via Computer Emergency Response Team. Each was derived entirely from his reading of user documentation. Later he earned a seat on the DHS Open Vulnerability Assessment Language advisory board for his work on software patching. In recent years he uncovered material security flaws in each of the first three iterations of a popular “secure element” hardware wallet, again from review of user documentation. Thirty years of self-study in free market economics was reinforced by extensive global travel. In visiting over 80 countries he has interacted with people on five continents. Still often traveling on a motorcycle with only a shoulder bag, he obtains intimate understanding of global economic realities. From Zimbabwean black market currency traders, to Tanzanian coffee pickers, Venezuelan refugees, Mongolian shepherds, Okinawan jazz musicians, Lao monks, etc. – the world is not as often presented. The ability to integrate these diverse and relevant experiences led to Cryptoeconomics. This is your next stop.

¿Qué es la renta básica? ¿Por qué la han defendido tanto liberales como socialdemócratas, comunistas, feministas o ecologistas? ¿Es eficiente desde el punto de vista del crecimiento económico y de la creación de empleo? Y sobre todo: ¿es justa? Éstas son algunas de las preguntas a las que da respuesta Juan Ramón Rallo en Contra la renta básica, un libro que aborda la que probablemente termine siendo la política redistributiva más importante del siglo XXI. En contra de lo que suele pensarse, la principal razón por la que el autor rechaza la renta básica no es económica, sino ética: la solidaridad es un fin muy loable, pero no puede ser impuesta por la fuerza. «No es el fin el que justifica los medios, sino que son los medios los que permiten justificar los fines»: también en el caso de la redistribución estatal de la renta. Según demuestra Rallo analizando críticamente las principales corrientes filosóficas contemporáneas como la socialdemocracia, el republicanismo, el comunismo, el utilitarismo, el feminismo o el ecologismo, la redistribución coactiva de la renta no puede justificarse desde un punto de vista ético: forzar a una persona a subordinar sus proyectos vitales a los proyectos vitales de los demás es injusto, intolerante y contrario a las bases sociales de la convivencia. De ahí que sólo el liberalismo proporcione un marco de justicia que permite el desarrollo moral de cada individuo sin interferir violentamente sobre el desarrollo moral del resto de individuos. Y de ahí que la renta básica, al vulnerar la mucho más básica libertad personal, sólo nos aleje de ese ideal de una sociedad genuinamente voluntaria y cooperativa. En el presente ensayo no sólo encontrará la crítica más completa y sistemática a la redistribución coactiva de la renta por parte del Estado, sino también todo un tratado de filosofía política dirigido a reivindicar y defender el liberalismo como una realista utopía integral e integradora frente a sus principales alternativas ideológicas.

El Dalai Lama nos ofrece el mensaje sereno de un hombre que ha conquistado la paz interior. En El arte de la felicidad el Dalai Lama nos ofrece el mensaje sereno de un hombre que ha conquistado la paz interior y sabe que la felicidad no es un don, sino un arte que exige voluntad y práctica. Lejos de las grandes teorías y muy cerca de las preocupaciones cotidianas de cada uno, de nuestros miedos y nuestros deseos, el maestro se ha servido de la ayuda de un psiquiatra occidental para entregarnos unas palabras que nos orienten en la vida diaria. Solo así seremos capaces de convertir el deber de vivir en el placer de sentirnos vivos en un mundo donde casi todo es posible, incluso la felicidad.

Cuarta novela de la hilarante saga del Mundodisco. En esta entrega, Mortimer es un joven soñador y despistado a quien le toca en suerte una inesperada tarea: convertirse en aprendiz de la Muerte y aplicarse en liberar almas de su envoltura carnal. A decir verdad, Mort no está demasiado capacitado para ello, y en una de sus primeras misiones, liberar el alma de una atractiva princesa que está a punto de ser asesinada, decide en su lugar «liberar» el alma del asesino, interfiriendo así en los designios del Destino y provocando el consiguiente desaguisado. Por su parte, la Muerte, habiendo delegado buena parte de su trabajo en Mort, se dedica a beber, jugar a los dados y embarcarse en enrevesadas reflexiones filosóficas...

NEW YORK TIMES BESTSELLER • NAMED ONE OF THE BEST BOOKS OF THE YEAR BY THE ECONOMIST  “The most important book on decision making since Daniel Kahneman's Thinking, Fast and Slow.”—Jason Zweig, The Wall Street Journal   Everyone would benefit from seeing further into the future, whether buying stocks, crafting policy, launching a new product, or simply planning the week’s meals. Unfortunately, people tend to be terrible forecasters. As Wharton professor Philip Tetlock showed in a landmark 2005 study, even experts’ predictions are only slightly better than chance. However, an important and underreported conclusion of that study was that some experts do have real foresight, and Tetlock has spent the past decade trying to figure out why. What makes some people so good? And can this talent be taught?   In Superforecasting, Tetlock and coauthor Dan Gardner offer a masterwork on prediction, drawing on decades of research and the results of a massive, government-funded forecasting tournament. The Good Judgment Project involves tens of thousands of ordinary people—including a Brooklyn filmmaker, a retired pipe installer, and a former ballroom dancer—who set out to forecast global events. Some of the volunteers have turned out to be astonishingly good. They’ve beaten other benchmarks, competitors, and prediction markets. They’ve even beaten the collective judgment of intelligence analysts with access to classified information. They are "superforecasters."   In this groundbreaking and accessible book, Tetlock and Gardner show us how we can learn from this elite group. Weaving together stories of forecasting successes (the raid on Osama bin Laden’s compound) and failures (the Bay of Pigs) and interviews with a range of high-level decision makers, from David Petraeus to Robert Rubin, they show that good forecasting doesn’t require powerful computers or arcane methods. It involves gathering evidence from a variety of sources, thinking probabilistically, working in teams, keeping score, and being willing to admit error and change course. Superforecasting offers the first demonstrably effective way to improve our ability to predict the future—whether in business, finance, politics, international affairs, or daily life—and is destined to become a modern classic.

This little book was written to accomplish something big: economic literacy. It is intentionally kept very short to be inviting rather than intimidating. You will gain life-changing understanding of how the economy works in practically no time. Per Bylund will make you excited about what economics has to offer. Because economic literacy is mind-opening. Sound economic reasoning is an enormously powerful tool for understanding both the economy and society. Economic literacy uncovers what is going on under the surface and why things work out as they do. There is no magic to it. In fact, economic literacy is necessary to properly understand the world. Short, direct, axiomatically unassailable, and devastating to the mythology of modern economics. This book not only promote Mises' views, but refutes and attacks the tragicomic orthodoxy of today’s economics mainstream.

New (2023) 10th Edition contains many updated techniques, scripts, and tools! It is time to look at OSINT in a different way.
