I trained a small model to do syntax highlighting in the browser with GPU. Meet gpu-lexer from Vercel Labs: Small (27.5KB), fast (runs on WebGPU), and language-agnostic (model guesses the syntax). gpu-lexer.vercel.app It is experimental and built for learning!

Introducing /visual-plan - a skill to generate rich, visual plans for Claude Code and Codex. Plan mode in Claude Code is incredible. But I always find my eyes glazing over when it gives me this huge markdown essay in my terminal. I found I can make much better visual plans with reusable components. So I made a skill called `/visual-plan`. It generates plans as MDX with visual, interactive components. Diagrams, interactive API specs, schema design changes, annotated code, and even pan and zoomable wireframes. So for any UI work, you can look at a wireframe first, comment on it, iterate, and then have the agent work. I’ve found this to be a much more intuitive interface for reasoning about what the agent is doing. It’s somewhat inspired by that popular post about how HTML is better than Markdown. But HTML can be slow and verbose to write. And it doesn’t look good checked into a repo. This has really made me feel like humans and engineering are entering a new abstraction phase, where we reason about things at the plan level. As long as the plan is good, agents are getting more and more reliable at executing on it. Almost to the degree that we trust the C compiler to compile to assembly reliably. Plans are the new intermediate representation. I also made a skill for the reverse of this, called `/visual-recap`. After the agent works, it gives you a recap of everything it did. Same idea: wireframes, interactive API specs and diffs, schemas, annotated code, etc. So now when you’re reviewing what the agent did for you, or looking at a pull request of somebody else’s code, you can see a visual recap instead of just reading a wall of text. It’s all free and open source. You can find it on my GitHub. Will link to it in the reply because we all know how dumb these algorithms are with links.

Vandaag speelt regen de hoofdrol op de weerradar, maar zaterdag waren de insecten heer en meester! 🦟 Op warme, rustige lentedagen vullen ze de onderste luchtlagen massaal, en worden ze zichtbaar op de ongefilterde radarbeelden. Daarbij onthullen ze de atmosfeerstructuur! 🧵

De #natuurbrand op 't #Harde in een Copernicus Sentinel 2C satellietopname van 12:51 NL tijd. Combinatie van visuele kanalen en SWIR om de brand zichtbaar te maken.

Earthset. The Artemis II crew captured this view of an Earthset on April 6, 2026, as they flew around the Moon. The image is reminiscent of the iconic Earthrise image taken by astronaut Bill Anders 58 years earlier as the Apollo 8 crew flew around the Moon.

Op TicketBewust.nl kun je kaartjes 'bestellen' voor voetbalwedstrijden en muziekconcerten. In werkelijkheid is het een nepwebshop (van de politie) om mensen te waarschuwen voor #ticketfraude. politie.nl/nieuws/2026/janua…

Watch Firefly land on the Moon! After identifying surface hazards and selecting a safe landing site, #BlueGhost landed directly over the target in Mare Crisium. A historic moment on March 2 we'll never forget. We have Moon dust on our boots! #BGM1

Good morning!! We thought the Apple liquid metal invite was so cool. How fun would it be if everyone could see their logo in liquid? So we made an app to let you make your logo in liquid. Just drag in your logo and see. Link inside the thread. We think you're gonna love it!

Oppassen voor deze scammers! Als je een tweet plaatst met klachten over @PostNL, reageren zij en vragen om je postcode, huisnummer en trackingcode. Daarmee misbruiken ze de app om jouw pakketje te laten bezorgen op een ander adres en dan bij jij het kwijt. Slim bedacht overigens.

Every time a sale is made on @Shopify this Black Friday weekend, it shows up on this 3D globe. It runs at 120fps in the web with a full 3D environment, physics engine, music synth, VR support, and more. It’s hard to believe it's a React app 👀🧵

Ik ging naar de Zuidas om mensen de stuipen op het lijf te jagen. Voor een item over AI bij Eva wilden we laten zien hoe eenvoudig en vooral éng gezichtsherkenningstechnologie is. Helemaal in combinatie met smart glasses. Een paar seconden video tijdens een gesprekje over het OV was genoeg om hun naam, werkgever en allerlei rare details op te zoeken.

Jarenlang vond Zwerfinator op de raarste plekken plastic sausbakjes. Die werden vervangen door sauszakjes om de #plastictoeslag te ontwijken. Die vindt Zwerfinator nu overal. Terwijl saus ook zonder plastic kan. Yo @McDonaldsNL check this out, bring the dip back and pump it up!

Totality: An HDR composite image of yesterday's eclipse. This photo used 5 cameras to capture thousands of photos during a 4 minute period. My goal was to capture the magic of the visual experience, and I hope this photo evokes similar emotions I experienced while watching it.
