Ask HN: Can you share websites that are pushing the utility of browsers forward?
My site https://james.darpinian.com/satellites/ uses WebGL, Web Workers, WASM, Service Workers, Notifications API, Geolocation API, probably some other web platform features I'm forgetting.The use of workers and WASM is not obvious, but on page load it takes the current orbit parameters for every orbiting satellite that is potentially visible anywhere on Earth and calculates the future position of each satellite every few minutes for the next 5 days, and then checks each future position for visibility from your location (accounting for sun angle, earth occlusion, sky brightness etc), all client side before page load finishes. WASM allows me to use the canonical satellite propagation tools (SGP4, written in ancient C translated from Fortran) and workers let me use multiple cores and not block the UI too much.
