🦠 µnix is a UNIX-like operating system

Non-unix, custom-API hybrid OS kernel written in C++ which can be thought of as an emulated microkernel. The native API is almost fully asynchronous and the kernel is aimed at high-scaling, high-throughput-requiring multiprocessor workloads, with working support for SMP and NUMA already implemented.
