Elizabeth Gilbert wrote an excellent article on how to use #Wasm for service chaining and composition with WASIP3! bytecodealliance.org/articles/how... #WebAssembly #BytecodeAlliance
How Wasm components enable pluggable tooling through interposition
And how the splicer framework makes it tractable at any interface edge.

State of WASI support for CPython: March 2026
It's been a while since I posted about WASI support in CPython! 😅 Up until now, most of the work I have been doing around WASI has been making its maintenance easier for me and other core developers. ...

WebAssembly is a second-class language on the web, but how can we make it first-class? WebAssembly Components could be the answer… hacks.mozilla.org/2026/02/maki...
Making WebAssembly a first-class language on the Web – Mozilla Hacks - the Web developer blog
This post is an expanded version of a presentation I gave at the recent WebAssembly CG meeting in Munich. WebAssembly has come a long way since its first release in 2017. The 1.0 version of…

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.”

During the last year and a half, I wrote a book on server-side WebAssembly. Getting into Wasm is hard. Resources are scattered, the tech is complex, and it's constantly changing. I wanted to contribute a resource to make learning easier. manning.com/books/server... (1/5) 🧵

Sarah Drasner@sarahedo.bsky.social · 2y agoAh- there’s a group called the ByteCode Alliance. Perhaps @lukewagner.bsky.social has more thoughts here.
I've been working on Hyperlight for more than three years now, and each month almost, I became more convinced this was a real step forward for cloud-native infrastructure. opensource.microsoft.com/blog/2024/11...
