A modular, non-POSIX operating system for x86_64, built from scratch in C and assembly. Intended to be educational and experimental while rigorously following a Plan9-style "everything is a file" philosophy, featuring a from-scratch ACPI AML parser, EEVDF scheduler and a pseudo-capability namespace based security model.
