PatchworkOS: a 64bit non-POSIX OS where everything is a file
Patchwork is a 64-bit monolithic NON-POSIX operating system for the x86_64 architecture that rigorously follows a "everything is a file" philosophy. Built from scratch in C it takes many ideas from Unix, Plan9, DOS and others while simplifying them and sprinkling in some new ideas of its own.
