It's an operating system that I am making in a youtube series that can be found here It's intended to show people how to make their own bare metal applications for the aarch64 architecture.
I've always been fascinated with low level topics and operating systems touch on a huge amount of topics.
Exploration is the best way to learn something, so this is my way to learn about this while showing others the results of my learning process.
Libraries hide a lot of the complexity.
That can be a good thing for production level software but it's usually a bad thing for learning since you can just call the functions and treat them as a black box.
I'm writing everything myself in order to actually understand what I am doing.
