One can still appreciate how well the violinist on the Titanic played while listening from a life-boat (if lucky enough to have been on one).

It’s a cool hack - what can I say. Surprised at how it instantly loads to a usable shell, too, if there’s a lesson to be learned there. Is there a freeze-dried memory image being used?

Absolutely not. The app starts at the entry point and execute instructions as normal. Both the main executable and libraries are all loaded on demand from a disk image delivered chunk-by-chunk over HTTP. The disk backend is based Clouflare workers with multiple levels of caching to maximize perf.
