Why I Use WebAssembly (nasso.dev)
WebAssembly (abbreviated “WASM”) is one of my favorite pieces of technology. It pushes the boundaries of what web applications are and what they can do. Did you know that today, you can just npm install @ffmpeg/ffmpeg and have a WASM build of FFmpeg that runs entirely in your browser? Those ad-flooded online file converters that everyone uses (because they’re just one web search away, really) can now work entirely on the client and become “offline file converters”!

Abusing DuckDB-WASM by making SQL draw 3D graphics (Sort Of) (hey.earth)
I had this slightly crazy idea: Could I ditch most of the conventional JavaScript game loop and rendering logic and build a 3D game engine where SQL queries did the heavy lifting?

WebAssembly: How to Allocate Your Allocator (nullprogram.com)
An early, small hurdle diving into WebAssembly was allocating my allocator. On a server or desktop with virtual memory, the allocator asks the operating system to map fresh pages into its address space (sbrk, anonymous mmap, VirtualAlloc), which it then dynamically allocates to different purposes. In an embedded context, dynamic allocation memory is typically a fixed, static region chosen at link time.

WebAssembly on exotic architectures (a 2025 roundup) (recoil.org)
It's about the time of the academic year to come up with project ideas! KC Sivaramakrishnan, Andy Ray and I have been looking into FPGA/OCaml matters recently so I thought I'd review the latest in the land of Webassembly for non-traditional hardware targets.

Compilation of JavaScript to WASM, Part 3: Partial Evaluation (cfallin.org)
This is the final post of a three-part series covering my work on "fast JS on Wasm"; the first post covered PBL, a portable interpreter that supports inline caches, the second post covered ahead-of-time compilation in general terms, and this post discusses how we actually build the ahead-of-time compiler backends. Please read the first two posts for useful context!

Yoke: Infrastructure as code, but actually (xeiaso.net)
Yoke is a project that takes this basic idea to the next level. With Yoke, you write your infrastructure definitions in Go or Rust, compile it to WebAssembly, and then you take input and output Kubernetes manifests that get applied to the cluster.

4 mains or nothing at all (andrews.substack.com)
In my previous post, I explored how Binaryen's Asyncify helped me implement setjmp in WebAssembly, successfully working around WASI libc's dependency on the 'exception handling proposal' - a feature still unsupported by the majority of WebAssembly runtimes.
