Ana Obregón, una de las mujeres más queridas y reconocidas de nuestro país, nos ofrece un desgarrador testimonio sobre la pérdida de su hijo Aless Lequio, tras una larga y dura enfermedad. El corazón de este libro es El chico de las musarañas, el texto que Aless empezó a escribir cuando le diagnosticaron cáncer. Un relato sincero, ácido, irónico, vibrante, con un sentido del humor único, que no pudo terminar, y que nos descubre el talento, el carisma y la personalidad de un joven que, sin duda, hubiera triunfado como escritor. A través de estas páginas, Ana se desnuda en un viaje de esperanza, lucha y fuerza, donde muestra un huracán de sentimientos y emociones sin filtro, en el que sumerge al lector en una experiencia inolvidable. La prueba de amor más bonita de una madre, una narración conmovedora, que sobrecogerá y en más de una ocasión despertará una sonrisa cómplice.

¿Cómo podemos beneficiarnos de las promesas del Gobierno y evitar al mismo tiempo la amenaza que éste supone para la libertad individual? En este libro ya clásico, Milton Friedman presenta el compendio definitivo de su influyente filosofía económica. Su objetivo principal es analizar el papel del capitalismo competitivo. Ese sistema económico, dice Friedman, es una condición necesaria para la libertad política. Pero una pregunta recorre estas páginas: ¿qué papel debe desempeñar el Gobierno en una sociedad libre, que confía principalmente en el mercado para organizar la actividad económica? Publicado por primera vez en 1962, Capitalismo y libertad es una de las obras de teoría económica más importantes que se han escrito. Su prolongada influencia la ha convertido en un referente: ha vendido casi un millón de ejemplares de la edición original, se ha traducido a diecinueve idiomas y sigue ejerciendo un poderoso influjo en el pensamiento económico y el trabajo de autoridades políticas y económicas de todo el mundo. Sus planteamientos sobre el mercado, la libertad y el Gobierno son, aún hoy, un modelo fundamental para el liberalismo y para quienes ven en las decisiones económicas libres una condición imprescindible para la libertad política.

What is money? How does it work, and what effects does it have on our society and economy? Hardly anyone has penetrated the answers to these questions better and explained them more comprehensibly than Alfred Lansburgh, who published them in the form of letters to his son, under the pseudonym “Argentarius” in his publishing house “Die Bank”. This edition contains the following collections of letters from the years 1921 to 1923: * On Money * Valuta * The Central Bank * Monetary Crisis

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.

In this instant New York Times bestseller, renowned economist Thomas Sowell demolishes the myths that underpin the social justice movement “Light on rhetoric, seriously heavy on data, and accessible in style, there is a reason why Sowell has been described as ‘among the most brilliant thinkers in the world today’ by Harvard University’s Steven Pinker and an ‘American sage’ by the Wall Street Journal.” – Washington Examiner The quest for social justice is a powerful crusade of our time, with an appeal to many different people, for many different reasons. But those who use the same words do not always present the same meanings. Clarifying those meanings is the first step toward finding out what we agree on and disagree on. From there, it is largely a question of what the facts are. Social Justice Fallacies reveals how many things that are thought to be true simply cannot stand up to documented facts, which are often the opposite of what is widely believed. However attractive the social justice vision, the crucial question is whether the social justice agenda will get us to the fulfillment of that vision. History shows that the social justice agenda has often led in the opposite direction, sometimes with catastrophic consequences.  More things are involved besides simply mistakes. All human beings are fallible, and social justice advocates may not necessarily make any more mistakes than others. But crusaders with an utter certainty about their mission are often undeterred by obstacles, evidence or even fatal dangers. That is where much of the Western world is today. The question is whether we will continue on heedlessly, past the point of no return.

Social media is changing the community. Several may speak up, but under such apparent freedom of expression, an undercurrent of conformity, obedience, self-censorship, and fear dominates. This is how tolerance turns into intolerance and political freedom into totalitarianism. Distinctive attitudes and individuality are replaced by group affiliation, where those who think differently are ostracized. We sense something disturbing: A community moving toward greater control. And a growing risk of politics with totalitarian features that, instead of fighting for freedom, wants to curtail it.
