An OS in pure Rust with its own TCP/IP and TLS 1.3 stack, fetching the live web
Summary
Rusty Penguin is a pure-Rust, bare-metal OS that includes its own TCP/IP and TLS 1.3 stack and even an on-board Linux ABI compatibility layer to run unmodified binaries. The project demonstrates building a complete OS stack from scratch while enabling real-world web access, highlighting both ambitious scope and practical steps toward a Rust-first ecosystem. It emphasizes security-conscious design choices and a commitment to a Linux-compatible binary world without relying on a Linux kernel.
