The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.

The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.

Access to all other Claude models is not affected.

We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

[ClaudeDevs @ClaudeDevs]

As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models.

Here’s what this means for you:

Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error.

On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models.

We know this is a disruption to your workflows; we appreciate your patience and support.

CEOs are uniquely prone to AI psychosis because they’re sufficiently distant from the last mile of work that still has to happen to generate most value with AI.

So when they play with AI, they see the happy path results, often not considering the next 10 or 20 things that have to happen to get sustainable results from agents.

“Look I made this awesome product prototype”. Yes but you didn’t have to review the code before it went into production and fix a bunch of issues.

“Look I generated a contract”. Yes but you didn’t verify all the terms before it goes out to the counterparty and didn’t have to wire up all the past contracts to work with.

The best thing you can do as a CEO is to use AI a *ton* to figure out the real implications of agents in the enterprise, and come out the other side with an appreciation for both the upside and the real work that goes into them.

Idea: An anonymous “vote to end meeting” button on Teams where if 50% of people press it, the meeting ends immediately.

We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.

This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.

Buenísimo esto.

Cuando operás un CEDEAR, estás comprando una representación emitida en Argentina de las acciones de Estados Unidos. Va un ejemplo:

Apple cotiza en USA a $263 USD y en Argentina a $19.160 ARS, a su vez sabemos que el múltiplo de emisión para AAPL es de 20:1. Es decir que 20 CEDEARs de AAPL equivalen a 1 acción. Por lo tanto:

- 20 CEDEARs de AAPL = $383.200 ARS
- 1 Acción de AAPL = $263 USD

Esto genera un tipo de cambio implícito:
$383.200 ARS / $263 USD = 1.457 ARS/USD

Como el mercado de CEDEARs y el de acciones son mercados separados, esto puede generar desarbitrajes en el tipo de cambio.

Por ejemplo, si hay un fat-finger en el mercado local y el CEDEAR sube repentinamente, digamos a $20.000 ARS, quedamos pagando un TC por encima de mercado.

$20.000*20/$263 USD = 1.520 ARS/USD

Esto es más común en acciones menos líquidas, aunque siempre hay arbitradores aprovechando estos desarbitrajes.

Para bien o para mal, estas cosas impactan en el rendimiento de tus inversiones y es importante entenderlo bien y saber qué estás pagando cuando operás un CEDEAR.

Before it took off, the bird ate parts of its own liver, kidneys, and gut. That was the only way to be light enough to fly. Then it flew 8,425 miles from Alaska to Australia, in 11 days, without eating, drinking, or landing once.

The bird is called B6. It's a bar-tailed godwit, four months old, weighing about as much as a can of beans. In October 2022, scientists at the US Geological Survey tracked its flight from Alaska all the way to Tasmania. The trip took 11 days and 1 hour. It is still the longest non-stop flight of any animal on Earth.

For two weeks before takeoff, godwits eat until they almost double in weight. Fat ends up being 55% of their body, more than any bird ever measured. Then they shrink their own insides. About a quarter of their liver, kidneys, stomach, and intestines gets broken down and reused for fuel, making room for the extra fat and cutting weight. Their heart and wing muscles grow bigger at the same time.

They never drink along the way. The water they need comes out of burning fat, the same reaction their muscles use for energy. They also never really sleep. B6 flapped its wings for 264 straight hours, cruising around 35 miles per hour with help from storm tailwinds. By the time it landed, it had lost almost half its body weight. The shrunken organs grew back over the following weeks.

Scientists still cannot explain the navigation. B6 had never made this flight before. Adult godwits leave Alaska weeks earlier, so young birds fly alone with nobody to follow. How a four-month-old bird finds its way across 8,425 miles of open ocean to a place it has never seen is still an open question.

About 100,000 bar-tailed godwits leave Alaska every fall. Most of them land in New Zealand or Australia 10 or 11 days later, having eaten parts of themselves to get there.

Uno de los tweets más importantes de la historia de Elon Musk. Está diciendo simplemente que la desocupación que genere la inteligencia artificial debe ser compensada por subsidios del gobierno, en la magnitud que sea necesario para cada persona o familia, y que a tal efecto ni siquiera se requiere que los recursos del estado sean genuinos vía recaudación fiscal, que hay que emitir lisa y llanamente moneda fiat al infinito. Dice que esta falsificación monetaria no irá a precios y que no habría inflación, porque del lado de la oferta las máquinas compensarán con producción todos los bienes y servicios que la sociedad requiera mediante IA. Musk está reformulando así las leyes económicas naturales que rigen el funcionamiento de la sociedad. Propone una nueva economía política, que anula todo lo escrito desde el mercantilismo hasta la actualidad incluídos Smith, Marx, Keynes, von Mises. Y, por supuesto que propone una nueva política económica, casi leninista. Musk deroga la teoría del valor-trabajo y la teoría subjetiva del valor al mismo tiempo, recurre a una sección marginal del pensamientio económico perdido cual es la teoría del valor-escasez dejando de lado por completo la demanda que ahora puede ser ilimitada porque la escasez no existiría más según su visión. También anula la teoría de los precios, la oferta y la demanda en el mercado y al mercado mismo. Se acerca, increíblemente y sin quererlo, a la planificación central de la economía por parte del estado y al comunismo total, el que no pudieron lograr exitosamente la URSS, el maoísmo, Fidel Castro, el Che Guevara y el Khmer Rouge camboyano, los que habrían fracasado solo por razones tecnológicas. Musk ve una sociedad sin precios, de producción organizada por el poder, sin capitalismo, sin ahorro, sin crédito, implícitamente sin bancos que creen secundariamente dinero. Porque el estado emite y reparte por un lado, y por el otro organiza la producción. En su modelo perderían sentido el mercado de valores, no habría más ricos ni pobres, todos serían iguales. Es una descripción terrenal del paraíso la que ve, un comunismo "lindo" y aburrido donde la vida ya no tendría sentido humano y todos pasaríamos a ser casi animales sin uso de la razón. Elon Musk trae con sus ideas la panacea universal, la fuente de la juventud y la piedra filosofal todo junto, y también hasta la misma llegada del mesías, gracias a la IA. Yo creo que está equivocado, ideológica y científicamente, pero da para desarrollar ideas fuertes en torno de este tweet que esta noche, a mi, me impide dormir.

Google descubrió un truco muy estúpido para que la inteligencia artificial te responda MUCHO mejor. Mientras todo el mundo busca el prompt perfecto, escribe instrucciones complejas y técnicas con nombres elegantes... unos investigadores de Google descubrieron que lo que mejor funciona es copiar y pegar tu pregunta dos veces.

 ¡Sí, así de simple! Le mandás el mismo texto dos veces seguidas y la IA responde mejor.

Probaron con Gemini, ChatGPT, Claude y DeepSeek: en matemáticas, razonamiento y comprensión lectora mejoró en todo. En un caso, un modelo pasó de 21% de precisión a 97%.

¿Y por qué carajo funciona esto? Porque la IA lee tu mensaje una sola vez, de izquierda a derecha, sin poder volver atrás. Si tu pregunta está al final, todo el contexto de antes se procesó sin saber qué le ibas a preguntar. Es como leer un capítulo entero de un libro y recién al final alguien te dice: "ah, buscá cuántas veces aparece la palabra perro". Ya es tarde. Pero si lo leés dos veces, la segunda vez ya sabés qué buscar.

Mientras vos buscabas el prompt perfecto, la respuesta era Ctrl+C, Ctrl+V. A veces la solución más bruta es la más inteligente.

On Scott Adams.

A man finds, to his astonishment, that he exists. After the elation of childhood wears off, he asks, who am I, why am I here, how does this work? These are hard questions, so after a brief struggle, he selects a readymade answer and goes about the motions of life.

Scott Adams was not such a man. He was a live player, ever curious, intent on figuring out this simulation that he found himself in. From first principles, Scott unraveled, understood, and ultimately controlled his own reality. He hacked himself with affirmations, others with persuasion, the world with simultaneous sips. He explained people as moist robots, two movies happening on one screen, his world as Gods’ debris. He carved a personal mission to “be useful,” and made us all better writers, public speakers, and persuaders. He preached the footwear theory of motivation, the Adams Law of slow-moving disasters, the skill stack, systems over goals, and of course, the Dilbert Principle.

Besides cartooning, philosophizing, and teaching, Scott rose to the occasion and displayed, “the one virtue that cannot be faked” - courage. Scott had the courage to speak honestly as he saw it - about Trump, about his nation, and about his time, even though it cost him friends, audience, money, and his ticket to polite society. Scott had true courage, the kind that makes you unpopular, the kind that is always and everywhere in short supply,

At the end, as any hacker of reality, Scott covered all of his bases - he left as a Buddhist, a Christian, and a player in the Simulation.

Scott, we didn’t get enough time with you, but you were a mentor and a marvel. You were useful and you were courageous. You were incompressible and indivisible. One of a kind, and generous with your drawing, writing, and speaking. Unlike your squealing critics in the chattering class, you will be read generations from now.

On this earth there are many long-lived hells but no lasting heaven. Each heaven must be created and nurtured, ex-nihilo, from mind and from mud. Scott, you created a small heaven for us all, and to a larger heaven you go.

A man finds, to his astonishment, that he no longer exists. He asks why, what it was for, and how will the new reality work? When the rest of us get there, we’ll find Scott, ever useful, ready to explain, having figured it all out.

Cuando empezamos las obras en Pedro Goyena vimos que pasaban muchos chicos y chicas con discapacidad visual. Averiguamos y descubrimos que era la Escuela de Educación Especial N°33 Santa Cecilia.

Nos presentamos y les pedimos ayuda para hacer nuestro menú en braille.
La directora y la vicedirectora (Evangelina Vallejo y Natalia Aprea) lo diseñaron, y hoy vinieron a entregarlo junto a decenas de alumnos que pudieron recorrer la fábrica.

Una experiencia inolvidable.
Nos contaron que ningún comercio de la zona se había acercado jamás a pedirles asesoramiento.

Ojalá esta iniciativa contagie a otros emprendedores. Les aseguro que llena el alma.
