49 snippets de Web Performance que se pegan en la consola de DevTools y te dicen por qué tu web va lenta. Cero instalación, cero dashboards, cero esperar al reporte de Lighthouse. Lo mantiene @nucliweb (Joan León), GDE en Web Tech y Cloudinary Ambassador. 1.4k stars en GitHub. 🧵
The WebMCP origin trial is now available in Chrome 149 → goo.gle/4x97wMK Sign up to integrate experimental features for live testing and help shape future iterations of the API. Build structured tools so agents can complete tasks accurately without guessing your UI.
Apuntado a esta formación online que da @nucliweb para aprender a tratar con multiagentes y a construir MCPs orientados a web performance.
Llevo tiempo viendo demos de multiagentes y casi todas sufren de lo mismo: un agente escribe y otro revisa... para acabar haciendo una todo-app No son malas demos, pero no hay un motivo técnico real para dividirlas en agentes. Así no aprendemos cuándo sí tiene sentido Abro hilo
Chrome 149 DevTools is out → goo.gle/4v55cVT Here's what's new: 💡 Agent walkthrough & Copy to coding agent in AI assistance 🎨 CSS Code Completion from Gemini in the Styles tab 🤖 WebMCP debugging tools in Application panel 🚀 DevTools for agents 1.0 with custom tools
Friend: Hey, Joan, can you give us a hand? Me: Sure, send me the URL DevTools: It takes nearly 3 seconds to load the WordPress plugins Me: 🫠
The new @GoogleColab bridges the gap between local environments and the cloud, providing a zero-friction execution platform for developers and AI agents alike. The CLI Supports: ⚡️ Agent-driven Colab workflows ⚡️ Instant GPU/TPU provisioning ⚡️ Remote script execution ⚡️ Interactive runtime access (console/REPL) Learn more in the blog: goo.gle/4dNPhF6
Este fin de semana he podido conocer a Edu, ver su Keynote en @commitconf, y conversar con él, y tengo muy claro que quiero leer ese libro 📖
Hoy publico mi primer libro: «Menos software, más impacto». Da un poco de vértigo. La tesis: tu equipo no va lento por escribir mal código. Va lento porque escribe código de más. 🧵
@MeNeMinem @commitconf Sí, cuando se publique la comparto

Long-running AI agents can run tasks over hours, days or weeks. Here's a few of my thoughts on them from @googlecloud's Agent Factory.

“Most teams fall into a reactive performance decay cycle: ship, wait for complaints, panic, patch, repeat. The Fast by Default model provides a repeatable alternative that keeps systems healthy.” Performance Engineering in Practice, by @denodell #WebPerf #Performance
AI coding agents can write code, but they can't see if it actually works. Chrome DevTools for agents 1.0 fixes this. The stable release brings powerful browser debugging, emulation, and automated audits to your AI assistants via our Chrome DevTools MCP server. 👁️ Give your agent eyes on the runtime → goo.gle/42K7Rrl #GoogleIO
Prepare your site for AI agent interaction with Lighthouse → goo.gle/3ReK3JD If you want AI agents to actually navigate your site properly, the new experimental audit in Lighthouse lets you see: ☀️ Discoverability for AI agents ⚡ WebMCP integration 👀 AI accessibility #GoogleIO
