It's "quietly public" but I've been working on a novel kernel design, this (12th, and final) rewrite undergoing development for about a year now.

https://github.com/oro-os/kernel

It's a user-less, capability-less microkernel design that enforces access control via the kernel's entity hierarchy. Shared memory ports with various levels of safety are the primary form of IPC, typed at the kernel level.

Currently undergoing later stages of the kernel efficacy stage; if I can prove the design I'll do a more formal writeup. It's been a project in my head for about 8 years and in the editor for about 4 now.

In OSes like these, I always enjoy reading about how the bootloader is kickstarted and how the OS is loaded. I don't know why :)

I find that part interesting too. There are a lot of chicken-and-egg situations you have to solve with them. Interesting breed of challenge.
