these lenses are out of control (and yes the match isn't exhaustive, wanted to keep the code short)

✍️ Just published a new post about my most-anticipated CSS proposals from Interop 2027! If you’re not familiar, the Interop project is a collaboration between browsers to pick shared focus areas. There’s *so much* good stuff this year, it was hard to pick just 10!

made a thing on the laser cutter last night jaredforsyth.com/projects/bak...

did anyone else play a ton of blobby volley as a kid? So it turns out the source is GPL 😁 been adding a ton of fun stuff to it (after porting to rust, ofc)

I love the clarity of this argument www.erichgrunewald.com/posts/why-i-...

this is very cool github.com/ocsigen/wax a syntax for wasm (w/ bidirectional compilation) that looks like it's actually nice to use!

New post! "Automate typescript refactors with dosido" I made a tool to move files and definitions around, and for extracting folders into new monorepo packages. jaredforsyth.com/posts/dosido...

ever done a jigsaw puzzle on a torus before? 🤔 🧩

I'm so proud of my voronoi puzzle piece generator

Anyone up for a little local-first crdt-backed collaborative wordsearch? crdt-wordsearch.quick.jaredforsyth.com?peer=3e27c3a... while supplies last 😅

somebody stop me, I'm creating an everything app. vega charts, slide decks, polls 🎉

did somebody say inline math? no? well here it is anyway! seamlessly integrated into the collaborative editing experience.

real-time collaborative, rich-text ... mermaid diagrams? Sure why not 😄

annnnotations! proving out "marks, but more complicated". and yes, you can have a footnote in a footnote, or a comment on a footnote in a popover etc.

to whom it may concern: 6 characters is enough to represent a thousand years of minutes in base 36. 9 characters is enough to represent a thousand years of milliseconds.

@slim.bsky.social @geoffreylitt.com what are the chances of peritext w/ block formatting happening? The paper talks about it as future with

At our seders, inspired by the one year we had a herpetologist guest, I invite attendees to speak in praise of frogs just after the plagues bit. If nobody has anything nice to say about frogs, I read them an abridged version of this weird lil story: sacred-texts.com/jud/jftl/jft...

I guess I'm 🤖 writing a type checker for gleam? in gleam ✨ because we need more educational examples of real-world type checkers! I'm calling it "gloat" 🐐 github.com/jaredly/gloat

/6 ICE is a monument to totalitarianism, lawlessness, and bigotry. It should be ripped out and woodchippered root and branch and replaced with something focused on the concept that you can’t defend the rule of law by burning it down.

I don't think this made it into my Bob Weir profile a few years ago. "If you don't you're in trouble."
