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.

Mark Russinovich: “Working towards enabling Windows driver development in Rust”
I didn't realise that. Then again, I only experimented with AOT executables quite briefly. Perhaps Cosmos[1] stuck in my head more than what I read about AOT dotnet applications.

Sweet C#
there are entire toolkits for that! https://github.com/cosmosos/cosmos
- Making an OS with C#?
- XenOS, an OS made in C#!
-
Does Microsoft ever try to written the whole windows OS codebase in entirely in C# in future?
This is about the same time that Cosmos came about - they’ve got they own ASM-like flavour of C# called X# and IL2CPU
- Slow Frame Rate under Cosmos
- Writing a kernel in C# on Linux
- Alternatives to COSMOS?
-
Is C# a good programming language for kernel development?
I recommend you to take a look at the Cosmos project. It's an operating system construction kit integrated to Visual Studio using it's own compiler translating IL code (C#, VB.NET, F#...) to x86 assembly.

Found this on a command-line only OS.
From these lines of code one would assume so, but apparently Cosmos seems to be quiet more serious than just a simple shell.

Biscuit 3.0
No, it isn't the third release of a POSIX like OS research written in Go,

If I know neither Go or Rust, which do I choose to learn first/only?
But there are other brave people exists like biscuit or gopher-os who can do it :)))

Pre-Overengineering
That's something I found in doing a bit of a dive on why ripgrep is so fast at doing a very specific kind of string search workload (Gallant / burntsushi / author of ripgrep is an actual wizard and contributes to Rust's regex engines, for reference). I wrote tiny proof of concepts in a variety of languages, all in my same style -- and sometimes my Go variants were as fast as the equivalent Rust/C (even in release / -O3/2 (every once in a blue moon, O3 makes no diff or is a slight regression in some exec paths)). I eventually found something about benchmarks in a related area, leading to this: https://benhoyt.com/writings/count-words/#performance-results-and-learnings. Somebody on the Go sub even linked me to the Biscuit OS: https://pdos.csail.mit.edu/papers/biscuit.pdf, which, tidbit, has Jon Gjengset (Crust of Rust legend) in the contribs list (https://github.com/mit-pdos/biscuit).

Rust: A Critical Retrospective
Go has been used to implement OS kernel code, e.g. in the Biscuit OS from MIT: https://github.com/mit-pdos/biscuit
Of course, the garbage collector did not exactly make it easier - but it's an interesting piece of software.
- Can Go be used for kernel development?
- GOLang in embedded systems
-
GOLang in embedded systems (1 physical threads)
https://github.com/mit-pdos/biscuit says 5% slowdown over C. Garbage collection is going to require some more RAM, generally <=2x though.
- Biscuit operating system written in Go
- The difference between Go and Rust
What are some alternatives?
Aura-Operating-System - AuraOS, the Franco-English Operating System developed in C# using Cosmos!
regex-automata - A low level regular expression library that uses deterministic finite automata.
KernelSharp - C# Kernel Mode Driver example using NativeAOT
TinyGo - Go compiler for small places. Microcontrollers, WebAssembly (WASM/WASI), and command-line tools. Based on LLVM.
Singularity-OS - Microsoft Research Singularity RDK 2.0 Source
Harbol - Harbol is a collection of data structures and miscellaneous libraries, similar in nature to C++'s Boost, STL, and GNOME's GLib; it is meant to be a smaller and more lightweight collection of data structures, code systems, and convenience software.
EfiSharp - An Attempt at building at least some of C# corelib for EFI applications. Inspired by https://github.com/MichalStrehovsky/zerosharp to see if this possible.
gopher-os - A proof of concept OS kernel written in Go
snapbox - Snapshot testing for CLIs
zerosharp - Demo of the potential of C# for systems programming with the .NET native ahead-of-time compilation technology.
usbarmory - USB armory - The open source compact secure computer
