This is why I still love PHP. Every request is a fresh start, compiled on the spot for the user, rendered, and then gone forever. Like tears in the rain 🌧️

Please please Apple let me use @claudeai as a Siri replacement

With Claude down this morning I'm back on Codex Claude feels like 2000s Apple and Codex is 100% Microsoft

@JimboStanford @rabbleca Jimbo if you believe the Cuban numbers I have bridge for sale 😂

Marco Rubio justifies US attacks on Cuba on grounds its economy doesn't "work". But measured by how GDP lifts human well-being, Cuba's economy "works" surprisingly well. How you use GDP is as important as how much you produce. My take in @rabbleca: rabble.ca/economy/how-to… #canlab

@emzanotti please @SouthPark roast these socialist cosplayers

This trip to Cuba is everything I’d hoped it would be and more. “We need food, aid, and a new government.” “Best we can do is Hasan Piker and a mural.”

Loving the strong pushback from real operators to the latest round of VC “thought leadership” 😂

TikTok. The most “viral” app in history bought every single user. I know because *I SPENT IT* I was there. I oversaw paid budgets for Musicaly/TikTok launch in 2017 Every growth metric you saw… PAID! There was no flywheel. There was MASSIVE paid budgets.

@RewiringK12 @anishmoonka Hi, I'd love for you to try @AporiaApp where I'm trying to build a Socratic AI

@anishmoonka Khanmigo still leaves a lot to be desired. Socratic AI tutors are the future but we’re not there yet.

Sal Khan was one of the first people on Earth to see GPT-4. OpenAI called him in the summer of 2022, months before ChatGPT existed, and showed him what was coming. He couldn’t sleep that weekend. By March 2023, Khan Academy launched Khanmigo, an AI tutor built on GPT-4, the same day OpenAI unveiled the model to the public. They were a launch partner. While every other education company was figuring out what ChatGPT meant for them, Khan Academy had already been building for seven months. The “obsolete” platform now has 120 million yearly learners. Khanmigo, their AI tutor, grew 731% year over year in the 2024-25 school year, reaching 2 million users. In classrooms alone, adoption went from 40,000 students to 700,000 in a single year, with projections past 1 million for 2025-26. Their teacher tools are free in over 70 countries. In January 2026, Khan Academy signed a deal with Google to put Gemini (Google’s AI) into new Writing Coach and Reading Coach tools for middle and high schoolers. They’re now working with both OpenAI and Google. A peer-reviewed study published in PNAS (one of the top scientific journals in the world) in January 2026, with researchers from Stanford and the University of Toronto, found that more Khan Academy usage is directly linked to higher student test scores. Sal Khan wrote a whole book in 2024 called “Brave New Words” arguing AI would save education. Sam Altman wrote a blurb for it. His TED Talk making the same argument was one of the 10 most-watched of 2023. In October 2025, he was named TED’s “vision steward.” Khan Academy is now the AI education company. That 731% growth happened while students spent 7.7 billion minutes learning on the platform in 2025.

There's worry that people will stop using their brains with LLMs, but managing several AI agent threads in parallel has been some of the most cognitively intensive work I've done in years

@PawelHuryn Cowork desperately needs a Git integration so it can escape my computer

Everyone's excited about Dispatch. The bigger story: Code, Cowork, Web, and now Dispatch are all converging toward the same thing — a persistent AI layer that follows you across devices and contexts. But the actual differentiator isn't the client. It's your knowledge layer. I keep my entire content system in .md files in a GitHub repo. Claude reads them in every session — Code, Cowork, or Web. Switch devices, kill sessions, move between tools — same context every time. The seams are still visible: - Dispatch needs your PC awake - /schedule doesn't work in cloud sessions - /loop sessions expire after 3 days - Code on the web can't render artifacts - Cowork has no native GitHub sync Within a year these come closer. The teams building each surface are clearly heading there. The knowledge layer converges even if the surfaces stay distinct. The question isn't which Claude client to use. It's whether you've built the knowledge layer that makes any of them useful.

This is a great post. Strongly recommended if you are writing PRDs and Spec Docs with LLMs What works for me: - No technical details on PRD, separate TDD as needed - List your core product principles at the top, do several passes with your agent, ask it to list issues one by one and let YOU make the decisions - Keep doing passes until doc is consistent, Claude/GPT will get lazy “the doc is pretty solid” ignore them, keep going until they cannot find more issues - Do a final manual review with fresh eyes after all the obvious issues have been fixed

@MarioJPenton galletazo sin mano jajaja

❌#ULTIMAHORA #BreakingNews Marco Rubio desmiente artículo del NYTimes que afirmaba que el "solo busca quitar a Díaz-Canel y hacer cambios económicos en Cuba"👇 La razón por la que tantos en los medios de EE.UU. siguen publicando historias falsas como esta es porque siguen confiando en charlatanes y mentirosos que dicen estar al tanto como sus fuentes. SECRETARY OF STATE MARCO RUBIO (X)

@USEmbCuba @14ymedio @yoanisanchez

La prensa independiente Cubana tiene la función clave de informar al Cubano de a pie y al mundo de la verdadera situación en la isla. Un gran gusto reunirnos con @14yMedio @Yoanisanchez y Reinaldo Escobar. #LibertaddePrensa #PressFreedom

@felixrieseberg well now I gotta get a Mac Mini 😅

We're shipping a new feature in Claude Cowork as a research preview that I'm excited about: Dispatch! One persistent conversation with Claude that runs on your computer. Message it from your phone. Come back to finished work. To try it out, download Claude Desktop, then pair your phone.

@MarioJPenton Por otro lado... la entrevista quedó tan buena que lo único criticable es tu pelado 😂

Que si el traje es azul claro, que si el pelado, que si no soy tan alto, que si tengo arrugas, que si me hago las cejas (que me las hicieron mi mamá y mi papá) 🤣🤣🤣 ¡Fíjate en la esencia! No soy modelo ni aspiro a serlo. Yo no soy lo importante, soy solo un instrumento. Una entrevista tan linda y que te quedes en las ramas 🙄. Vaya, ahí te dejo el link de nuevo por si no la viste ¡Buenos días! #CubaLibre2026 youtu.be/-FtLtK6avPw

@MarioJPenton “esto no es una dictadura y el que diga lo contrario va preso” 🤡

@eltoquecom y el link??

Desde principios de marzo de 2026, el nombre de una empresa de reciente creación en Cuba ha circulado entre empresarios en Estados Unidos con negocios de envío de remesas. Se trata de Antilla Capital, una entidad que se presenta como la primera institución financiera privada del país. En un mensaje firmado por Maridiely Cabrera Moreno, quien se identifica como presidenta de la empresa, aseguran que están constituidos como Sociedad Anónima (S. A.) y que cuentan con la aprobación del Banco Central de Cuba. Efectivamente, el 24 de febrero de 2026, mediante la Resolución 17, el Banco Central emitió una licencia a favor de Antilla Capital para ejercer como institución financiera no bancaria. Entre las capacidades que el Banco le otorgó a esa institución, se encuentran la gestión de pagos digitales y transferencias electrónicas y la facilidad de «gestionar y distribuir remesas, así como desarrollar cualquier otra actividad relacionada con la trasmisión de dinero en el territorio nacional». La aparición de Antilla Capital ocurre en un contexto de negociaciones entre el Gobierno cubano y el de Estados Unidos, que contendría un importante componente de apertura al sector privado cubano. Pero, ¿quién está detrás de esta empresa? En una búsqueda profunda pudimos encontrar información sobre la presidenta de la nueva compañía, Maridiely Cabrera Moreno, que la ubican asociada o como propietaria o representante de varias empresas en el extranjero y en Cuba. Si quieres conocer todos los detalles, entra el link en el primer comentario.

@allgarbled I know but I still like it 🤷‍♂️

I don’t know what you call them, but these little side tabs are like the emdash of vibe coded UIs
