Runtime.JS: V8 JavaScript Kernel

on YouTube ↗23m

" summary

A tiny experimental kernel called Runtime.JS runs directly on hardware (targets KVM) with a built‑in V8 engine, executes JavaScript only (no binaries), and exposes a single address space of software‑isolated V8 instances with RPC between isolates. IO is nonblocking system‑wide, supports zero‑copy ArrayBuffer transfer for network buffers, boots to a JS shell in the demo, and successfully handled UDP/SSH in tests; project is ~8–10 MB and not Node compatible.
