#wasm — Public Fediverse posts

🚀 Spring Boot running in your browser tab. Just because I can!

I wrote up the journey, some numbers, and a few things I learned along the way.

Hopefully a fun read. Feedback very welcome! 😄

RE: https://kittsteiner.blog/blog/2026/no-client-side-media-processing-in-non-chromium/

#til about "client-side media processing" via #wasm. In my world, that should run on the server. Guess I'm getting old. 🤓

Seems to be clever to circumvent some server challenges, but you need to test it across all browser. Interesting nonetheless.

Cлучилось то, что я обычно советую не делать: я не выбрал из существующих 14 форматов, а сделал 15-й.

Acho incrível como essas ferramentas para #desenvolvimento #web com #rustlang têm evoluído. Hoje temos o #dioxus, que é um #react #framework e compila #wasm. O backend é #axum integrado. Sensacional.

I wonder why we do not have a repository for wasm components and their wit based descriptions, like we have mvnrepository etc for the jvm world. Does anyone know of such an effort?

wkg already allows to upload in an OCI compatible style. What would be required now, is to make this searchable.

I recently posted that I created a WIT mode for emacs, now a mode for Webassembly Composition files (WAC) followed. Read more here: https://www.reddit.com/r/WebAssembly/comments/1vn5ipb/emacs_modes_for_wit_and_wac_files_and_treesitter/

I like #webassembly, #wasm, the component model, #wit (webassembly interface types) and #emacs. Hence I wrote an treesitter based emacs mode for WIT files. The lack if support for it drove me crazy. Give it a shot (currently a manual install is required, a melpa package is planned)

Let's me introduce Firefly the new zig wasm plugin!

Install it, activate it, and add a few URLs to monitor, it will generate a beautiful status page for your production. Finally, a forge that lets you manage your app even after deployment!

Available now on the main branch, or in the upcoming 0.5 release (planned for September).

Reminder: this is my first time writing zig code, so please be indulgent 😅

"surely abusing the #wasmtime debug api to hibernate my #wasm modules couldn't possibly go wrong…"

The first Zig plugin is almost ready to be merged! In the meantime, let's play a quick guessing game, can you guess what it's for?

Here are a few hints:

• it's a service we either don't have at all or have to pay for (never understood why our forges don't include it by default)
• it won't make much sense for gitroot on gitroot, but I'll use it anyway so I can show you what it looks like
• i had to add 2 new APIs to the plugin-sdk to build it: schedule and httpClient https://gitroot.dev/CHANGELOG.html#unreleased

To find out the answer and get notified when it drops, give me a follow ;)

It'll be available with the upcoming release planned for this September!

I've put a README on my pure #zig #fits library now that it is mature enough to do a great many things with binary tables:

You can even compile this library to #wasm for FITS in the browser. It's used in my kerrz #blackhole #raytracing demo and lets you download Cunningham's transfer function tables computed on your phone!

Новинки WebKit в Safari 26.6. Джен Симмонс разбирает небольшое, но полезное обновление: новый параметр compileOptions позволяет использовать JS String Builtins с WebAssembly compileStreaming() и instantiateStreaming(), не переключаясь на непотоковую компиляцию. Плюс восемь багфиксов в CSS, сети, service workers, веб-расширениях и WebRTC. #safari #wasm
