Webassembly: Expectation vs. Reality

on YouTube ↗02h 58m

" summary

WebAssembly is production-ready in modern browsers and the session proves it by compiling Rust and wasm-bindgen code and an Emscripten-compiled OpenCV build (a few megabytes) to run in-browser. Demo shows real work: webcam capture, convert frames to grayscale, run Haar cascades for face detection, draw rectangles and stream results at roughly ~15 fps vs ~2 fps for a JS baseline. Tools used: WebAssembly Studio, Node http-server, fetch/instantiate, wasm-bindings; code shows memory handling, pointer passing, and when wasm actually helps.
