¿Alguna vez te preguntaste qué hizo posible que las redes pudieran crecer sin colapsar? 💡 La ingeniera y matemática Radia Perlman diseñó el algoritmo detrás del Spanning Tree Protocol, el mecanismo que permite redundancia en Capa 2 sin generar loops. Gran parte de la infraestructura de red actual funciona gracias a esa lógica. 👇🧵

"Persistence of vision display" or POV display are LED devices that compose images by displaying one spatial portion at a time in rapid succession. One example are Hologram Fans.

@Agnes38751297 @HowThingsWork_ It's a zoetrope, an early animation device from the 19th century that creates the illusion of motion by spinning a cylinder with images viewed through slits.

How people watched movies before screens existed. We've come a long way! 😭

Full-circle Test-driven Firmware Development with OpenClaw Ladyada: "I've only had OpenClaw installed on this Raspberry Pi 5 for a couple of days, but boy, have we burned through a lot of tokens and learned a lot. Including what I think is a really fun improvement in my development process: “Agentic test-driven firmware development.” I've used LLMs for writing code as a sort of pair-programming setup, where I dictate exactly what I want done. But this is the first time that I'm giving full access to the hardware to the LLMs and letting Claude Opus 4.5 as a manager to control Codex subagents. Not only does it parse the datasheet for the register map and functionality, Claude also comes up with a full development and test plan, writes the library, tests it on existing hardware, and then also works up a test suite that covers all of the hardware registers to make sure that the library is exercising the entire chip capability. For example, here I give it an APDS-9999 color sensor and a Neopixel ring and tell it, “hey use the Neopixel ring to verify that we're really reading red, green, and blue data properly from the sensor,” and it will do the whole thing completely autonomously… no humans involved! I still review the final code and ensure the tests genuinely validate the functionality, not just take shortcuts. There is a phenomenon known as "reward hacking" (also called "specification gaming"). The model may optimize for passing tests as a metric, rather than ensuring the code truly works as intended. So far, the results have been excellent... no surprise, since these LLMs are trained on Adafruit open-source GitHub repositories!"

También hubo diversión para los peques con @gbarbarov, Ana y su proyecto @Scandlive_x . Pinta tu OSHWi y quedará nadando en este acuario virtual programado con Processing :) Era totalmente hipnótico. También trajeron un año más un Open LED Race pequeñito. ¡Hay mucho pique!
