Pele is a great library for rendering Mermaid diagrams to SVG. Wouldn't it be great if you could use it as a single executable with no dependencies?
Now you can! Pele as a single binary: github.com/jpsca/pele-cli
Today I learned about "curl_cffi", a Python binding for curl that can make it pretend it's a request from Chrome (or Firefox, or Safari) github.com/lexiforest/curl_c…

You've never seen 🐍Python like this, trust me :)
I've built an interactive 3D explorer of Python's parser & compiler pipeline. If you ever wanted to look under the hood and understand how Python actually works this is your chance.

There must exists an app with PHP, deployed on Railway, with calls to cURL, with other services written in node that use Brotli compression running on a couple day old Linux, with their code self managed on GitLab
They are having a hell of a week

BBC: We will speak with our BBC mechanic regarding car engines.
The BBC mechanic: I didn't know cars had engines until yesterday morning.
Crustaceans can finally make Mermaid diagrams without breaking their oath
The reason passkeys are controversial in one tweet. Being able to use a technology is way more important than one extra feature.
Replying to @indy_singh_uk
Passkey UX, portability and recovery are their own discussion, separate from the technical claims my post addresses.
I’m tempted to start a personal crusade for FreePascal over Rust. It’s just as fast, uses less memory, compiles in a few seconds, the code looks nicer, it’s stable, and LLMs know it well. Yeah, you manage memory yourself, but AI can handle that.

If you can write CSS, you can write GSS { ● }
I've been dreaming of this for years: a language to build 3D scenes like you write CSS. Selectors, cascade, :hover, keyframes… compiled to one GPU shader.
Meet GSS: GPU Style Sheets.

Le pedí “puedes extraer los efectos de sonido de este video o generar unos nuevos?” Y WTF!? No se nada de sonido así que a mi me suena como cuando en las películas se inventan diálogos sobre tecnología. “Esta usando un oscilador triangular de web audio, lo tenemos!”
El “control remoto” de Claude es maravilloso para emergencias. Tenía que salir así que deje abierta una sesión para buscar porque se había caído un app. Encontró la causa, conversamos desde el teléfono y aprobé que aplicara sus soluciones… y para cuando regresé a casa ya sabía que todo estaba arreglado

example.com just changed for the first time since 2013, and IANA replied to my email asking why.

For years, maybe a decade, I've wanted to build a writing tool that just did a few things I couldn't find anywhere else.
A system that mimicked how I think when I write. A system that provided clear affordances, features, and places to do the things I wanted to do. A way to play with my writing as I'm writing it. A way to settle into just the right way to say something.
It never made sense to make it a 37signals product because it's not commercially viable, nor would it be worth pulling people off their other work to hack on this. Plus, it would have taken months the old way.
So this weekend I just made it myself, with Claude's help.
It's called Write_On and the short video walks you through it.
Essentially it's "alternative control" at the word, sentence, and paragraph level, plus a way to dim stuff back, and stash stuff near by. Not version control, but alternative control. You'll see what I mean when you watch the video below.
So here it is. Write_On.
KDE releases: "Plasma no longer crashes when you delete a starred clipboard entry"
Omarchy releases: "We added 3000 new plugins, added support for running it on Casio watches, and achieved AGI"
Ahora que vamos a dejar de tener que escribir código ;), me acordé del mejor código que escribí en mi vida: exactamente cuatro líneas

La verdad, ponerle emojis a los logs hace que sean muchísimo más fáciles de leer. Era un escéptico hasta ahora.
Si, ya se, "¿que, recién lo descubres?". Perdonen, estaba ocupado gritándole a una nube.
