How Zoom’s web client avoids using WebRTC (via) It turns out video conferencing app Zoom uses their own WebAssembly compiled video and audio codecs and transmits H264 over WebSockets.
Pyodide: Bringing the scientific Python stack to the browser (via) More fun with WebAssembly: Pyodide attempts (and mostly succeeds) to bring the full Python data stack to the browser: CPython, NumPy, Pandas, Scipy, and Matplotlib. Also includes interesting bridge tools for e.g. driving a canvas element from Python. Really interesting project from the Firefox Data Platform team.
Wasmer: a Python library for executing WebAssembly binaries. This is a really interesting new tool: “pip install wasmer” and now you can load code that has been compiled to WebAssembly and call those functions directly from Python. It’s built on top of the wasmer universal WebAssembly runtime, written over just the past year in Rust by a team lead by Syrus Akbary, the author of the Graphene GraphQL library for Python.

Squoosh. This is by far the most useful example of web assembly I’ve seen so far: Squoosh is a progressive web app for image optimization (JPEG, PNG, GIF, SVG and more) which uses emscripten-compiled versions of best in breed image codec implementations to provide a browser interface for applying and previewing those optimizations.
