From the greatest hack of all time (asm.js) to running in billions of browsers, edge networks, and embedded systems. The oral history of WebAssembly's first decade, from the engineers who built it. bytecodealliance.org/articles/ten... #WebAssembly #Wasm #BytecodeAlliance
10 Years of Wasm: A Retrospective
In April of 2015, Luke Wagner made the first commits to a new repository called WebAssembly/design, adding a high-level design document for a “binary format to serve as a web compilation target.”

I just pushed v0.35 of SuperSonic - my port of SuperCollider's powerful synthesis engine scsynth to the web as an AudioWorklet.
This comes with a lot of performance improvements, improved bundler compatibility and much polish to the fun example.

I've been working on a new tool with @tonofcrates.bsky.social to make publishing easier called Rheo:
rheo.ohrg.org
In a nutshell, it lets you produce an EPUB, a PDF, and a static site (HTML) from a folder of @typst.app files. The Rheo doc site is naturally made with Rheo (PDF and EPUB linked).

I guess I didn't talk about this much publicly — I, uh, wrote a static site generator last year, to replace hugo and docusaurus for ink & switch.
I think the ratio of "niceness" / LOC is really high.
Also, I think the readme is a good read.
You can take it, hack it, and use it yourself. <3

Everything is in the system folder, and the top level readme covers the basics of how it works and some general philosophy.
NB — this SSG is worse than hugo in almost every way, except for the ones that matter most to us.
Feel free DM if you want lots more design / tech details.

This reflective acrylic sheet shows how 1980s illustrators were able to trace real-life objects on the computer. Once it was aligned, it reflected whatever was in front of it over the monitor's display, allowing artists to trace it in a tool like MacPaint or MS Paint. Simple, low tech and effective.

At some point the shape rotators, looking down on the wordcels, created an artificial wordcel.
After some time they noticed that the artificial wordcel was really good at rotating shapes.
Now the shape rotators are freaking out.

Here's a little spatial / tangible tool I made to explore an algorithm with my hands and eyes.
I saw an error diffusion matrix on wikipedia and it looked vaguely like a circle, so I built this board game-inspired tool to feel out just how spatial it actually was.
