Me llega este SMS. Obviamente no viene de Seur y es un ataque de phishing (no sigáis el enlace). Pero me hace gracia eso de que han hecho medio intento de entrega. Sin referirme en concreto a Seur, eso es lo que parece en ocasiones.

Mi hija coge el tren de Cullera a Valencia, para después coger el tren de Valencia a Almansa e ir yo del pueblo a recogerla a Almansa. El cercanías de Cullera a Valencia llega media hora tarde y cuando llega, el tren de Valencia a Almansa hacia 5 minutos que había salido, lo pierde por el retraso del cercanías, es raro que llegue algún tren a la hora, se va a ventanilla y le dice que tenía pagado el billete para ir a Almansa pero que lo ha perdido por llegar con retraso el otro, le dicen que no le cambian el billete, que tiene que comprar uno nuevo y que como ya ha usado el bono joven no lo puede volver a usar, el billete le había costado 1 euro por ese bono, ahora paga 14 euros por el billete de Valencia a Almansa, es inconcebible que @CercaniasVLC no tenga en cuenta que lo perdió por culpa de ellos mismos y de las políticas decadentes de @Renfe Para rematar hoy le llega un correo que ha comprado un billete de bono joven y no lo ha utilizado y que debe de enviar el motivo y justificarlo porque sino tiene una penalización de hasta 750 euros. ¿Qué mierda es esto @oscar_puente_? Como no me puede contestar porque me tiene bloqueado, espero que Cercanías y/o Renfe den la cara, es una auténtica vergüenza, y después ves al Puente hablando de todo aquí en X, menos hablar y más trabajar, que para eso te pagamos.

Para todos los que acaban de hacer los exámenes de la PAU, este hilo tiene importantes recomendaciones sobre la elección de estudios y universidad.
Replying to @antoniosanzmon
Los estudiantes tienen 12 huecos para elegir universidad y estudios. Hay que elegir por preferencia de estudios, independientemente de la nota de corte que se estime que pueda tener. El orden es importante porque si te admiten en una, no podrás elegir otra que esté debajo.

My CISO called me at 3 AM last Tuesday. "We caught someone." I asked, "Caught them doing what?" He said, "Typing." Let me explain. We have an employee in IT. Great worker. Always online. Never complained. Perfect Slack etiquette. One problem. His keystrokes were arriving 110 milliseconds late. One hundred and ten milliseconds. That's 0.11 seconds. The average American remote worker has 20-40ms of latency. This guy? 110ms. Every. Single. Keystroke. My security team ran the numbers. That latency doesn't come from a bad router in Ohio. That latency comes from Pyongyang. Our "Senior DevOps Engineer" was a North Korean operative. Running his work laptop through a laptop farm. In America. While he worked from a government building. In North Korea. He passed the interview. He passed the background check. He passed the vibe check. He did not pass the speed of light. Here's what people don't understand about physics: Light travels 186,000 miles per second. But it still has to go through China. And China adds latency. Since April, Amazon has caught 1,800 of these attempts. Eighteen hundred. I called an emergency meeting with my board. I said, "We need to implement Keystroke Velocity Auditing across all remote employees." They said, "That sounds invasive." I said, "You know what else is invasive? The Democratic People's Republic of Korea in your Jira tickets." They approved the budget. We now monitor keystroke timing to the microsecond. If your latency exceeds 60ms, you get a call from HR. If it exceeds 100ms, you get a call from the FBI. We've already flagged 47 employees. Turns out 44 of them just have bad Wi-Fi. 3 of them are "still under investigation." The lesson? You can fake a resume. You can fake a background check. You can fake an American accent on Zoom. But you cannot fake the speed of light. Physics is the ultimate background check. Hire accordingly.

My new article is on what I think is one of the worst problems of the years ahead: we are facing the end of progress against extreme poverty.
In the last decades, the world has made fantastic progress against extreme poverty. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 *billion* people. This means on any average day in the last 35 years, about 115,000 people left extreme poverty behind. Leaving the very worst poverty behind doesn’t mean a life free of want, but it does mean a big change. Additional income matters most for those who have the least. It means having the chance to leave hunger behind, to gain access to clean water, to access better healthcare, and to have at least some electricity — for light at night and perhaps even to cook and heat. Can we expect this rapid progress to continue? Unfortunately, we cannot. Based on current trends, progress against extreme poverty will come to a halt. As you can see in the chart, the number of people in extreme poverty is projected to decline, from 831 million people in 2025 to 793 million people in 2030. After 2030, the number of extremely poor people is expected to increase. To understand why the rapid progress against deep poverty will not continue into the future, we need to know why the world made progress in the past. Extreme poverty declined in the last three decades because, back in the 1990s, the majority of the poorest people on the planet lived in countries that subsequently achieved very fast economic growth. In Indonesia and China, more than two-thirds of the population lived in extreme poverty. But these economies then grew rapidly, so that by today, the share has declined to less than 10%. Other large Asian countries — including India, Pakistan, Bangladesh, and the Philippines — also achieved strong growth, and as a consequence, the share living in extreme poverty declined rapidly. Much of the progress happened in Asia, but conditions in other regions improved too: the share living in extreme poverty also declined in Ghana, Cape Verde, Cameroon, Panama, Bolivia, Mexico, Brazil, and many other countries. What is different today is that the majority of the world’s poorest people are stuck in economies that have been stagnating for a long time. Unless the poorest economies start growing, this period of progress against the worst form of poverty is over.

No me encaja el cálculo: - Solo la población del interior (en ambiente seco) puede enfriar agua en un botijo. Pongamos 25 M de personas. - Poca gente bebe más de 1 litro de agua fría al día. - En 90 días son 90*25*1  = 2250M de litros. (sigue)

- El agua del grifo (canalizada por el subsuelo) no sale helada en verano, pero tampoco caliente. Pongamos 20 a 25ºC. - El agua en la nevera alcanza 5 a 10ºC. Son unos 15ºC de diferencia con el grifo en promedio. (sigue)

- La nevera trabaja siempre. El extra de enfriar 15°C cada litro de agua supone 15 Kcal/l 2250 M de litros * 15 Kcal/l = 33750 Gcal = 39,225 GWh Son unos 40 GWh respecto a tu estimación de 1400. Nota: calculado mientras vemos en casa una serie de TV. Todo puede ser.

Bananas feel eternal. Always there, always cheap, always the same. But that’s an illusion. There is an emergency. A devastating disease - Banana Xanthomonas Wilt (BXW) - is ripping through East Africa. Once a plant is infected, it wilts, fills with yellow slime, the fruit rots, and the whole thing dies. Within weeks, the harvest is gone. Yields? Often 100% loss. For us in Europe, losing bananas would sting. For more than 70 million people in Africa, especially those who depend on starchy cooking bananas as their main food, it would be catastrophic. Scientists have tried to breed resistant bananas. But here’s the catch: cooking bananas are sterile. No seeds. No crossbreeding. New varieties take decades, and so far none are fully resistant. Some are tougher, yes, but they taste and cook differently - hardly a solution when people rely on them as daily food. This is where modern biotech shines: Ugandan and Australian scientists added two genes from bell peppers. ➝ Bananas became resistant without changing taste, yield, or texture. In Kenya, researchers used genome editing to switch off “self-sabotage” genes. ➝ Several banana lines turned out completely resistant to BXW. That’s not science fiction. Those are field results. The irony: Despite these breakthroughs, small farmers may never see them. Why? Because opposition to biotechnology - often fueled by Western NGOs - blocks adoption. The same countries where bananas are a snack luxury are telling Africans not to use the very tools that could save their staple food. Critics love to claim gene editing is “unnatural.” But let’s be clear: Nothing we eat today exists in the wild. Wheat, rice, potatoes, strawberries - every single one is the product of human intervention. Traditional breeding is messy. Thousands of genes get shuffled. Risks come along for the ride. Modern biotechnology is more precise. We know exactly what’s being changed. And more than 4,400 safety assessments in 70+ countries have shown the same result: GMOs are no riskier than conventional crops. Biotechnology isn’t just about saving bananas. It’s about speeding up what farmers have always done - adapting crops to survive diseases, droughts, and climate change. If we care about food security, we can’t afford to dismiss the very tools that may keep bananas - and millions of people - alive.

600'000 radiosondes ($100M) are lost in nature each year after being used for only 2h. The Meteoglider returns to home after each flight to be reused.. it has been tested by national weather services in Switzerland, France, Spain and Denmark. @NOAA it's your turn!

Tokenization has been the final barrier to truly end-to-end language models. We developed the H-Net: a hierarchical network that replaces tokenization with a dynamic chunking process directly inside the model, automatically discovering and operating over meaningful units of data

En las noticias: cabildeo, mordidas, prostitutas… personajes inmorales liderando lo público. Quienes tendrían que dar ejemplo de rectitud son quienes más destruyen la confianza de la ciudadanía en las instituciones. La Plataforma de Contratación del Sector Público es un instrumento esencial para la transparencia de la contratación pública. Su buscador de contratistas es sensible a las tildes: 🙂 Buscando «valencia» salen unos resultados. 😳 Buscando «valéncia» salen otros distintos. 🤨 Buscando «valència» salen otros más. Y ninguna búsqueda devuelve todos. Avisé de esto en 2023. Se lo envié al Ministerio de Hacienda. Y lo repito en cada congreso de contratación pública y administración pública a que me invitan. El público —funcionarios— alucina, se ríe, me da la razón… cuando mi conferencia acaba, todos me aplauden, hay un receso y pasamos al café. 🥂 Pero nada cambia. Nadie hace nada. Nadie se siente aludido. Nadie lo escala. Nadie se ruboriza. En dos años, nadie lo ha arreglado. Soy un desarrollador de software. ¿Sabéis lo que cuesta a un programador arreglar eso? Nada. Es solo un ejemplo —anecdótico, pero paradigmático— de la dejadez y la incapacidad de una parte de lo público. Estos y otros muchos problemas siguen rotos. Como ciudadano, solo me queda un recurso: expresarlo aquí, en las redes sociales, para tratar de llamar la atención de las autoridades sobre ello. Intentar hacerlo viral para que lo arregle por vergüenza quien no lo hizo por desidia. Mientras tanto, las noticias de corrupción, mordidas y escándalos en torno a la contratación pública arrecian. Son ya el triste y secular paisaje moral de mi país. Nuestras instituciones no necesitan más dinero, ni más congresos ni más cócteles. Necesitan un terremoto.
