I'm crying: We kicked off the X.​com rewrite this spring and it was a massive undertaking. The old web stack from 2006 was one of the last things holding back growth & engineering velocity. With a new Android app, a refreshed iOS app, and a completely rebuilt web stack, X has finally arrived to the promised land of product development: The only constraint now is what the team can dream up.
The web rewrite is working. On a slow connection, the old X web took more than 22 seconds to show the first post on a profile. The new X web does it in 2.7 seconds. Here's how we did it, and how we're rolling it out one country at a time. blog.x.com/en/engineering/re…

He juntado en una sola extensión de Chrome todas las de SEO que usaba. Y le he añadido algunas cositas más como comprobar qué bots de IA pueden entrar y navegar con su user agent en tu web o ver qué buscan ChatGPT, Claude y Perplexity antes de responder. Gratis. Todo lo que hace 👇

I’ve left Anthropic after more than a year of working on Claude Code and seeing it scale larger than I ever imagined. I have really loved working at Ant and believe deeply in the mission, and most of all, the idea of a race to the top. The idea that if we work hard and responsibly, we can raise the bar and inspire others to great outcomes. And if we all push each other to be better, things can be radically good. I will carry the spirit of this with me forever. My colleagues at Anthropic are the most talented, thoughtful, competent, and earnest people I have ever met. I am glad they are at the wheel and trust them deeply. To the community on X, thank you for everything. You’ve made this the most fun (and sometimes stressful) job I’ve ever had. For me, it is time for a bit of a break before diving into something new. If you want more excellent Claude Code content, you should follow @addyosmani , @lydiahallie, @_catwu, @ClaudeDevs and of course @bcherny who started it all.

Anthropic gave me $30,000 in Claude credits to research my own tumor I wrote what I built since March. I’m looking for someone who can manufacture a personalized vaccine, and a hospital that can give it

Recordad: dedicando poco esfuerzo habrán cientos haciendo miles de cosas. El valor ahí es nulo. Pero que dediquen el tiempo que merecen las cosas, con gusto y cariño, seguirán siendo muchos menos. Mientras la dinámica de invertir más trabajo para un mejor resultado siga aportando valor al público, habrá mercado. Ahora estamos en una fase transitoria en la que como podemos hacer lo que antes llevaba mucho curro en pocos minutos, nos parece fascinante. Pero somos de acostumbrarnos rápido (adaptación hedónica) y eso reajustará nuestras preferencias. Si queréis trabajar en algo, con IA o sin ella, dedicadle tiempo, cariño y trabajo. Aprovechad la oportunidad par elevar el nivel de calidad y ofreced algo que os destaque frente al resto. Siempre ha funcionado así y no va a cambiar ahora.

Update on rate limits in Codex. We’ve found (a) some inefficiencies when using images in long sessions with multiple compactions (b) high p95+ usage for Computer History (c) a feature that was meant to generate conversation titles that was draining a bit more usage than intended. And we have a tiger team combing through everything and shipping fixes tomorrow. We also found a novel approach to drive efficiency up significantly that is completely unrelated and we will be working on next week. As part of some of the fixes tomorrow, we will also do a full reset of the usage for all paid subscriptions. See you then.
Update on rate limits in Codex. We do see that for some users the cache hit rate has been worse this week than the stable state the weeks before. This could explain that usage is draining somewhat faster for those users as hitting the cache consistently is an important component of being efficient. We are investigating and will have an update tomorrow.

ARAGÓN ES UN PUÑETERO DESASTRE ❌ Hablando de Bomberos, Aragón es de lo peorcito de España junto a Castilla y León, diría. Mi primera y única experiencia con ellos fue pésima. En el año 2018 me ofrecieron un contrato temporal de conductor de autobomba en Teruel capital desde SARGA (Sociedad Aragonesa de Gestión Agroambiental) tras pasar el concurso de méritos para esa campaña. Cuando llegué para firmar a las oficinas tras el gasto de hoteles y gasolina porque soy de Extremadura, el contrato era totalmente diferente a las condiciones que me había ofrecido por teléfono. Me negué a firmarlo y encima hubo bronca (estaban calentitos porque no había quien cogiera ese contrato, de ahí que mintieran). Hoy día la situación en la Comunidad Autónoma es esta: - Bomberos Provincia de Zaragoza: En huelga indefinida desde 2024. Recientemente falleció en acto de servicio un compañero intentando salvar una vida. - Provincia de Huesca: Igual, pero han parado ahora la huelga para negociar temporalmente. - Provincia de Teruel: Conflicto abierto con la diputación. - Bomberos forestales autonómicos: En huelga actualmente. Los cuatros servicios de Bomberos de la CCAA en huelga o conflicto con la Administración por falta de personal y medios. Ya os digo yo que no va cambiar nada porque estamos ocupados en debates artificiales y absurdos que se alejan de lo importante. Pero si algún aragonés me está leyendo, que sepas que tienes muchas más probabilidades de morir en caso de accidente o incendio que otro español por el mero hecho de vivir allí.
Aragón es la región que cuenta con el menor ratio de efectivos, el menor ratio de autobombas y el segundo menor ratio de medios aéreos del país en proporción a sus hectáreas forestales. Es también la que más aeronaves estatales solicita elpais.com/clima-y-medio-amb…

Cuando la realidad supera a la ficción. Las medidas propuestas por Microsoft en la construcción de la locura del centro de datos de Zaragoza,para reducir el impacto del consumo de recursos materiales , parece escrito por Epi y Blas. Cerrar grifos cuando no se usan...y así todo.

First, they stole our data. Then, they sold it back to us. Now, they watermark it. Soon, they claim they own it all.

We promised open weights for Qwen3.8. Now, time to meet them! 🎉 ⚡ Qwen3.8-27B: - A native multimodal dense model. With just 27B parameters, it outperforms Qwen3.7-Plus overall and shines in real-world coding & office workflows. - 262K native context, easily extendable to 1M tokens via YaRN. - Built for builders. Highly efficient, high-quality, and licensed under Apache 2.0. 🚀 The open weights for Qwen3.8-2.4T-A95B (Max-level) have also been released recently. Whether you're shipping lightweight applications with Qwen3.8-27B locally or building agents with Qwen3.8-2.4T-A95B, they're yours now! Download, deploy, and build something we haven't imagined yet. 👀👇 - Hugging Face: huggingface.co/collections/Q… - ModelScope: modelscope.cn/collections/Qw…

The announcement for DeepSeek-V4-Pro-0813 has been retracted. Flash improved massively compared to the preview, but Pro barely showed any gains over its preview version. Looks like my guess was right: they probably deployed the wrong version of Pro.
🔥最新:DeepSeek官网已撤下V4 Pro 0813正式版公告! 公告内容已消失,但是API还挂着0813…… 是部署错了?还是实测不如V4 Flash 0731太拉直接回滚? 评论区说说你们还调用得了吗? #DeepSeek #V4Pro #梁文峰

Don’t fall for the fake Fox/GOP outrage. Two weeks ago the House passed a bill that greenlighted the transfer of Spanish territory to Morocco. Every Republican except me voted for it, but now THEY are acting shocked at the invasion. congress.gov/119/bills/hr859… congress.gov/119/bills/hr949…
