New #WasmAssembly podcast episode is up: Enabling in-browser scientific computing with #Wasm: David Kircos of Quadratic.

We discussed how Quadratic's spreadsheet uses #WebAssembly to enable scientific computing directly in the browser with tools like Pyodide, pandas, and numpy. The conversation also covers practical challenges such as bundling large-scale Wasm applications, exploring browser limitations, and Quadratic's integration of AI.

Compile the javac compiler to WebAssembly (WASM) and run it in the browser to compile Java code into Java bytecode or directly to WebAssembly.
Execute the resulting WASM bytecode in the browser, or run the Java bytecode in a Java Virtual Machine (JVM) in the shell.
Alternatively, execute the WASM bytecode within a WASM VM (Chicory)
running inside the Java VM.

Show HN: Faasta – A self-hosted Serverless platform for WASM-wasi-HTTP in Rust

https://github.com/fourlexboehm/faasta

New blog post! I decided to do a quick write-up of how to use WASM to create an almost pure-#Rustlang backend and frontend. There's still a lot of outdated content out there recommending to use a bunch of JS tools to get started with WASM, but it turns out it really isn't necessary anymore.

My consultancy @mainmatter has some availability for #frontend projects starting in May.

We have deep expertise in #svelte and #emberjs as well as the intersection of frontend and #rustlang, e.g. with build tools or #wasm.

wgpu: A cross-platform, safe, pure-Rust graphics API.

｢ wgpu is a cross-platform, safe, pure-rust graphics API. It runs natively on Vulkan, Metal, D3D12, and OpenGL; and on top of WebGL2 and WebGPU on wasm.

The API is based on the WebGPU standard. It serves as the core of the WebGPU integration in Firefox, Servo, and Deno ｣

JAWSM—a JavaScript to #Wasm compiler:
