Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

RTOS vs Standard Kernel for a first Hobby OS
A compiler and libc are entire projects in their own rights. For libc I can recommend mlibc (https://github.com/managarm/mlibc), its designed to be portable for hobby operating systems.

It Can Happen to You (another case of O(n^2) sscanf parsing)
You don't, here is a (not entirely complete) scanf implementation that doesn't use strlen. Other libc implementations seem to use strlen to feed the input data to a FILE struct so they can reuse their fscanf.

could I write an entire operating system in assembly and C++?
It’s very much doable; I did exactly this with an OS I worked on last year. This takes advantage of many modern C++20 features, most of which work just fine in a bare metal environment. As others have said, you’ll have to disable runtime features like exceptions and RTTI in your kernel. A lot of it is really hacky, but this was just meant to be a proof of concept project that got a little out of hand :)

Why is my AHCI PI register set to eight 1s if I only have two devices on the AHCI?
I’ve written an AHCI driver for my OS which I’ve tested works on a few VM platforms and real hardware. I’m not actively working on this project anymore due to my current job, but maybe it can be a useful reference for you.
