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.

- A tiny hand crafted CPU emulator, C compiler, and Operating System

Project Oberon the Design of an Operating System, a Compiler, and a Computer Pdf
this sort of exists at https://github.com/cksystemsteaching/selfie
> Selfie is a self-contained 64-bit, 12KLOC C implementation of: (...) a tiny (...) subset of C called C Star (C) (...) to a tiny (...) subset of RISC-V called RISC-U[;] a[n] (...) emulator (...) that executes RISC-U code[;] (...) a (...) hypervisor (...) that provides RISC-U virtual machines*
so they have an instruction set architecture, a compiler, and an operating system, though it's much simpler than xv6. because the instruction set is a subset of risc-v you can run its code on actual risc-v hardware (or qemu-system-riscv), but presumably you could also design risc-u hardware in verilog that was simpler than a full implementation of rv64i with whatever extensions the hypervisor needs
- Best book on writing an optimizing compiler (inlining, types, abstract interpretation)?
- Selfie: An educational platform for teaching systems engineering
- An educational software system of a tiny self-compiling C compiler, a tiny self-executing RISC-V emulator, and a tiny self-hosting RISC-V hypervisor.

500 Lines or Less – Writing a useful program in fewer than 500 line code – AOSA
Re the text editor, when I was writing an editor for my homemade CPU I used the one from this tutorial: https://viewsourcecode.org/snaptoken/kilo/index.html - it is 1000 lines of C.
I have diverged a bit from the tutorial because I didn't want syntax highlighting and I really wanted vi-style keybindings. Mine is at https://github.com/jes/scamp-cpu/blob/master/sys/kilo.sl (in my made-up programming language).

Designing a CPU for Advent of Code
In case you're interested, there's more about this project in the github repo: https://github.com/jes/scamp-cpu/ and on my blog: https://incoherency.co.uk/blog/tags/cpu.html

Scamp – a homebrew 16-bit CPU
This is really cool and unique. I poked around a bit, and the kernel is vaguely POSIX like, but written in a homegrown language with a compiler written in Perl[1].

My homebrew CPU is alive!
Actually, I just found this! That's pretty much what I was looking for. That's what I would have linked if it had been me posting. :) This looks like a really interesting computer project!
