Yo fui ingeniero en Meta, y siempre seguía FAIR desde adentro. Lo que acaban de publicar es la versión que les dejan publicar. Pero con eso, es más que suficiente para decirles exactamente que es lo que está pasando. TRIBE v2 predice, vértice por vértice sobre la corteza cerebral, qué zonas activa cualquier video. Sin escáneres. Sin humanos. Subes el contenido, obtienes el mapa neural (activación emocional, supresión de razonamiento crítico, modulación prefrontal) antes de que el video lo vea un solo usuario. Ahora considera la posición de Meta: 1. Tiene años de datos de Reels sobre qué contenido retiene atención, genera enojo, provoca compartir. 2. Saben empíricamente qué funciona. TRIBE v2 les da el mecanismo causal de por qué funciona (a nivel de tejido cortical) Eso convierte correlación histórica en capacidad predictiva sobre contenido nuevo. 3. Internamente hay herramientas que se llaman Gatekeepers y Quick Promotions que sirven para inyectar contenido en el feed de poblaciones arbitrarias a escala. 4. Simulador de respuesta cerebral + conocimiento empírico de contenido efectivo + maquinaria de distribución selectiva. El pipeline está completo. Y luego está Thiel. Inversor y amigo personal de Zuck. Fundador de Palantir, cuyo negocio es análisis de poblaciones a escala para gobiernos e inteligencia. NO es descabellado observar que confluyen los incentivos de plataformas construidas por las mismas personas. La licencia CC BY-NC dice que Meta retiene los derechos comerciales del predictor de respuesta cerebral más preciso jamás construido. Y recuerda, esto es lo que decidieron hacer público.

BREAKING: The nitrogen trap just closed. Three locks snapped shut simultaneously. The planting window is closing behind them. And the food the world eats next year is now being decided by molecules that cannot reach the soil in time. Lock one: the Strait of Hormuz. The IRGC permissioned corridor allows oil tankers from friendly nations to pay $2 million in yuan and pass. It does not allow fertiliser vessels to pass at any price. Zero approved fertiliser transits in 24 days. The Gulf supplies 49 percent of the world’s exported urea and roughly 30 percent of traded ammonia. That supply is not delayed. It is denied. The gate opens for molecules that fund the gatekeeper. It stays closed for molecules that feed the planet. Lock two: Russia. The world’s largest exporter of ammonium nitrate just halted all AN exports until after April 21. Three to four million tonnes per year, gone from global markets at the exact moment the Northern Hemisphere needs it most. The official reason is “domestic priority.” The strategic effect is leverage. Russia earns windfall revenue from the oil price spike its ally’s war created, then removes the fertiliser that farmers need to plant through the crisis. The disease and the cure, again, from the same address. Lock three: China. Beijing has banned exports of nitrogen-potassium blends and phosphate fertilisers through August 2026. China is the world’s largest phosphate producer and a major nitrogen supplier. The ban removes the last alternative source that could have compensated for Hormuz and Russia. Three locks. Three countries. Three deliberate decisions timed to the same biological calendar. The biological calendar does not negotiate. Corn requires nitrogen at the V6 to VT growth stage or kernel set is permanently reduced. Wheat requires it at tillering and jointing or grain fill collapses. Rice requires it at transplanting or yield drops 20 to 40 percent in low-input systems. These are not economic models. They are cellular processes. The plant either receives nitrogen during the window or it does not. If it does not, no subsequent application, no price increase, no policy reversal can recover what was lost. The damage is written into the biology of the seed. The US Corn Belt window closes mid-April. European top-dressing is happening now. Indian Kharif preparation begins in May. Bangladeshi Boro rice transplanting is underway this week. Every one of these windows is closing while the three largest sources of nitrogen on Earth are simultaneously locked: Hormuz by military blockade, Russia by export decree, China by trade ban. The USDA Prospective Plantings report arrives March 31. The FAO Food Price Index publishes April 3. These will quantify what the molecules already know: the nitrogen did not arrive. The yield loss is locked in. The 5 to 10 percent global drag will concentrate where the buffers are thinnest: subsistence farms in Bangladesh, Sub-Saharan Africa, South Asia, where a 20 percent shortfall does not mean lower profits. It means hunger. Sri Lanka banned synthetic fertiliser in 2021. Rice yields collapsed 40 percent. The government fell. In 2008, fertiliser and oil spiked simultaneously and food riots erupted across 30 countries. In 2026, the strait blocks fertiliser while Russia and China withdraw the alternatives, and the planting windows close on a planet with nowhere else to turn. The war is fought with missiles. The famine is fought with molecules. The molecules are trapped behind three locks on three continents, timed to the one calendar that cannot be paused, extended, or negotiated: the calendar written into the DNA of every seed in the soil.

JUST IN: The most irreversible consequence of this war is not happening in Tehran. It is happening in a barn in Iowa. A farmer is standing over a kitchen table looking at two seed catalogues. One is corn. One is soybeans. Corn needs 180 pounds of nitrogen per acre. Nitrogen costs $610 per ton on the CBOT March futures settlement as of yesterday, up 35 percent in a month. Soybeans fix their own nitrogen from the atmosphere through root bacteria called rhizobia. They need nothing from the Strait of Hormuz. The farmer is choosing soybeans. Millions of acres are choosing soybeans. And once the planter rolls into the field, the choice cannot be reversed until next year. USDA projected corn at roughly 94 million acres for 2026, down from 98.8 million. Soybeans at 85 million, up from 81.2 million. Those projections were published February 19, before urea surged past $683 at New Orleans. The actual shift will be larger. USDA Prospective Plantings reports March 31. By then the seeds will be in the ground. This is the transmission channel the world is not watching. A 21-mile strait enforced by provincial commanders with sealed radio orders just rewrote the planting economics of 90 million acres of the most productive farmland on Earth. Not through sanctions. Not through diplomacy. Through the price of a single molecule that corn cannot grow without and soybeans do not need. Now follow the cascade. The Renewable Fuel Standard mandates 15 billion gallons of corn ethanol annually. That consumes roughly 43 percent of the entire US corn crop. The mandate is set by the EPA. It does not flex when corn acres shrink. It is inelastic demand consuming a fixed share of a declining supply. When supply tightens against a fixed mandate, the remaining corn reprices upward. Corn above $5 per bushel compresses every margin downstream. The US cattle herd stands at 86.2 million head, a 75-year low per USDA NASS. Poultry and pork operations face compression from higher corn prices. Feed is the single largest cost in livestock production. When feed reprices, protein reprices. When protein reprices, every grocery shelf in America absorbs the increase. This is the protein cascade. Corn to feed to meat to eggs to dairy to the checkout counter. Each link tightens because the link before it tightened. The originating cause is a urea molecule that cannot transit a strait because a provincial commander’s sealed orders say it cannot. The farmer did not start this war. The farmer cannot end it. The farmer responds to the price on the screen and the biology of the two crops in front of him. Corn needs the molecule. Soybeans do not. At $610 the arithmetic is settled. The planter rolls. The season is locked. Israel just authorised the assassination of every Iranian official on sight. The US has spent $16.5 billion. South Pars is burning. The Fed is holding rates because oil inflation will not break. Gold touched $5,000. Bitcoin is bleeding. China is running exercises near Taiwan. Sri Lanka shut down on Wednesdays. And underneath all of it, a man in a barn is making the decision that determines whether four billion people pay more for food this year. He has never heard of the Mosaic Doctrine. He does not know what a sealed contingency packet is. He knows what nitrogen costs. And he is planting soybeans.

done. hermes agent now has a community on X. open source will only win when people stop being spectators and start using the tools that replace the ones controlled by proprietary corporations. you don't have to write code to contribute. use hermes instead of openclaw. NousResearch is open source in and out, from the models to the harness, everything is out there for you to run, break, fix, and improve. i encourage you to use their tools and when you hit a bug or have a feature request bring it here. this community is the place to share configs, report issues, help each other with setup, and push hermes agent forward together. 1k github stars was the start, 10K stars is where we are. 100K is next. join and let's make open source win. x.com/i/communities/…

Software horror: litellm PyPI supply chain attack. Simple `pip install litellm` was enough to exfiltrate SSH keys, AWS/GCP/Azure creds, Kubernetes configs, git credentials, env vars (all your API keys), shell history, crypto wallets, SSL private keys, CI/CD secrets, database passwords. LiteLLM itself has 97 million downloads per month which is already terrible, but much worse, the contagion spreads to any project that depends on litellm. For example, if you did `pip install dspy` (which depended on litellm>=1.64.0), you'd also be pwnd. Same for any other large project that depended on litellm. Afaict the poisoned version was up for only less than ~1 hour. The attack had a bug which led to its discovery - Callum McMahon was using an MCP plugin inside Cursor that pulled in litellm as a transitive dependency. When litellm 1.82.8 installed, their machine ran out of RAM and crashed. So if the attacker didn't vibe code this attack it could have been undetected for many days or weeks. Supply chain attacks like this are basically the scariest thing imaginable in modern software. Every time you install any depedency you could be pulling in a poisoned package anywhere deep inside its entire depedency tree. This is especially risky with large projects that might have lots and lots of dependencies. The credentials that do get stolen in each attack can then be used to take over more accounts and compromise more packages. Classical software engineering would have you believe that dependencies are good (we're building pyramids from bricks), but imo this has to be re-evaluated, and it's why I've been so growingly averse to them, preferring to use LLMs to "yoink" functionality when it's simple enough and possible.

Coisas que ninguém sabe sobre D. Pedro II, porque sua melhor biografia foi banida das livrarias no Brasil: 1) Era simples e despretensioso. Mantinha audiências públicas regulares. Qualquer pessoa, sem distinção de classe, cor, riqueza ou condição social podia apresentar pessoalmente suas petições ao Imperador. Todos eram tratados com respeito e afabilidade, traço pelo qual D. Pedro II se notabilizou. "O traço principal do seu caráter é uma tolerância inquebrantável, à prova de todas as tentações e de todos os gravames pessoais, e que por todos os títulos merece o nome de magnanimidade." (Joaquim Nabuco) 2) Recusava qualquer tipo de tratamento diferenciado no Brasil ou em suas viagens. “Em Lisboa recusou interromper, a seu favor, a quarentena imposta aos demais passageiros do vapor em que viajava; recusou depois os aposentos no Palácio Real, preferindo ir para um quarto do Hotel Bragança. Na Inglaterra recusou as carruagens do palácio e a guarda real, como recusou a hospedagem da Rainha, indo, como qualquer outro viajante de distinção, para o Hotel Claridges. Em França recusou as homenagens do Governo, e na Suécia e na Dinamarca a hospedagem real. E assim em toda a parte.” (Heitor Lyra) 3) Quando soube que seria expulso do país, em meio à comoção geral de sua família e de alguns amigos mais próximos, disse apenas: “Pois se tudo está perdido, haja calma. Eu não tenho medo do infortúnio”. Não se opôs nem à república, nem às humilhações que sofreu por aqueles que até a véspera lhe beijavam a mão. “Afastou-se da pátria com uma dignidade tão alta e emocionante, com uma grandeza de alma tão verdadeira e espontânea, que constituía, naquele momento, a melhor glória para o seu nome.” (Ramón Cárcano) 4) Após 49 anos de governo pacífico, já tendo aceitado o exílio, pediu permissão para assistir a uma última missa no dia seguinte, antes de partir. Teve, no entanto, a residência invadida de madrugada para ser, junto de sua família, jogado numa lancha, às escondidas da população. Idoso, com locomoção debilitada, foi obrigado a saltar da lancha a uma escada na embarcação que foi utilizada para expulsá-lo do país, correndo o risco de cair no mar. “A escuridão era quase completa. Apenas uma pequena lâmpada espalhava na escada tênue claridade. Ajudado de um e outro lado por Mallet e Motta-Maia, em vão o Imperador diligenciava passar da lancha à escada. Com um pé sobre a borda da pequena embarcação, dobrava-se para a frente, procurando livrar a cabeça de um golpe contra a tolda. O grande vulto, a fraqueza das pernas, a incerteza dos movimentos, tudo embaraçava o Imperador. Entre a lancha e a escada poderia ele cair e seria quase impossível salvá-lo.” (Heitor Lyra) 5) O Governo Provisório assinou um decreto oficial afirmando ter-lhe concedido um subsídio para se estabelecer na Europa, e que D. Pedro II o aceitou e agradeceu. Era falso. “O cinismo desta falsidade com que a história há de perpetuamente infamar os nomes dos signatários de tal decreto é tão extraordinário e revoltante que haverá quem entre em dúvida sobre a integridade mental e moral dos membros de um governo que não hesita em forjar e em assinar documento tão desonroso.” (Eduardo Prado) 6) Já no exílio, o Governo Provisório fez questão de formalmente bani-lo para sempre do Brasil. “Quando teve conhecimento da resolução do Governo Provisório, de o banir e à sua família, definitivamente, do território nacional, voltaram a indagar-lhe se não pensava em lançar um manifesto. Ele repetiu a mesma verdade: 'O meu manifesto será a minha vida.'” (Heitor Lyra) 7) Expulso e humilhado, tomado de incalculável tristeza, nunca praguejou, nem contra o Brasil, nem contra aqueles que o trataram como um criminoso. Dizia apenas: “A História me fará justiça, eis a minha fé consoladora”. Quando já estava muito enfraquecido e sentiu que ia morrer, “fez vir um punhado de terra do Brasil, do seu querido Brasil, que guardou discretamente no armário do quarto, num pequeno embrulho, ao lado do qual foi encontrado, depois de sua morte, um papel com estas palavras: ‘É terra do meu país; desejo que seja posta no meu caixão.’” (Heitor Lyra) 8) Teve o velório pago pela França, em agradecimento por ter sido D. Pedro II o primeiro chefe de Estado a visitá-la após a Guerra Franco-Prussiana. Governantes e celebridades do mundo inteiro estiveram presentes. Os oportunistas que tomaram o país de assalto não só esconderam e abafaram a notícia da população, como tiveram a desfaçatez de não enviar ao velório um único representante oficial.

the hype around this model settled fast. good. now i can test it without the noise. NVIDIA released nemotron cascade. 30B total, 3B active. fits on a single RTX 3090. hybrid mamba MoE. gold medal on the international math olympiad with only 3 billion active parameters. they say it beats qwen on math, code, and reasoning. i tested qwen 3.5 35B-A3B on a single 3090 at 112 tok/s. now same card, same tests, different architecture. mamba vs deltanet. nvidia vs alibaba. receipts incoming tonight.
