hi friends I'm very excited to announce Halfspace, my experimental cross-platform IDE for solid modeling with distance fields! This has been in progress since midway through last year, and it's finally "done enough" to make it more public.

Look what a beautiful torment nexus, so many threads to read! 🤩

Yesterday there where echoes of @getdweb.net camp at @berlinfediday.berlin.social.ap.brid.gy by @cypherhippie.bsky.social Awesome to see AT Protocol and ActivityPub getting closer together and join the fight against centralisation instead of wasting energy with infighting - this is the way!

As a PL designer, this space is one of the most unclear/undecided as to what are the “correct” semantics. This one deserves some first principles drawing board and hammock time

you know, i thought the reputation of cousot papers was at least a little exaggerated but no, they actually look like that lol (this is page 3)

New blog post: "Dependent if expressions without dependent types" This trick lets you write code like: example bool = if bool then 5 else "hi!" … with only one language extension: RebindableSyntax haskellforall.com/2026/09/depe...

Excellent visualization! This is basis of the technique I called "turbulence" which I use in my tiny shaders for fluids, smoke and fire. It's cheap and deterministic

I’ve alway’s thought it’s a shame that WebAssembly has the word “web” in it. Gives it a connotation that it’s “only for browsers” or something.

 Meanwhile, NASA’s over here with a flight-compliant derivative (SpaceWASM) intended for spacecraft!

#ResistanceRoots Tye Leung Schulze was born on this day in 1887 in San Francisco. She became the first Chinese American woman to vote in a U.S. election and the first to be employed by the federal government. She dedicated her life to serving the Chinese community that had once ostracized her. /1

there is no such thing as "age verification." All "age verification" is actually "identity verification." You can coat it in glitter and "privacy-preserving" wrapping paper. But in the end, mandating age verification means mandating surveillance be built into software and hardware. Period.

A friend recently created an open jobs posting for freelancers in the media production industry. If you or others you know are in that industry, feel free to share; and I hope this helps! Updated daily, at least.

Reflection — such an important topic. Excellently produced and presented. I love the historical contexts. Also, JVM is S-tier as far as Reflection goes... most JVM languages/programers, unfortunately, treat more as a static compilation target. Probably an erlang/OTP sitting somewhere in there...

Wow this is cool, @graham.systems made a peer-to-peer agent messaging system for Letta, built on Iroh tangled.org/hollis.pds.g...
