WebAssembly? Web and Assembler? WTF!
summary
WebAssembly (born 2015, in Chrome/Firefox by early 2017) and Emscripten are used to compile C/C++ into .wasm plus JavaScript glue so binaries run in Node and browsers. The talk shows concrete demos: OpenCV engines and ML inference compiled to Wasm, running in web workers with a pseudo-filesystem to enable CLI-like tools in-browser (e.g., airplane detection in seconds). It reports typical performance beating JavaScript (sometimes ~2×), though still below native, and notes JS↔Wasm call costs and loading overheads.
