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.

Oasis – a small, statically-linked Linux system
Michaelforney has also built croc [1], a qbe based C compiler. Really impressive!

Minias – A mini x86-64 assembler for fun and learning
A word of warning for those wondering: this is not for Intel syntax, despite referencing the Intel doc.
Minias can assemble itself
...but it's written in C and uses a parser generator? IMHO it feels a bit backwards --- and perhaps even a bit cheating if you're doing this for a "bootstrap pilgrimage" --- to write a lower-level tool in a higher-level language. On the other hand, the same author also links to a C compiler in C, without a parser generator: https://github.com/michaelforney/cproc

Running the "Reflections on Trusting Trust" Compiler
The C4 compiler [https://github.com/rswier/c4] is a self-hosting compiler for a subset of the C programming language that produces executable x86 code. You can understand and audit this code in a couple of hours (its 528 lines).
It could be an interesting exercise to bootstrap up from something like this to a working linux environment based solely on source code compilation : no binary inputs. Of course a full linux environment has way too much source code for one person or team to audit, but at least it rules out RoTT style binary compiler contamination.

Flattening ASTs (and Other Compiler Data Structures)
I was surprised to see nodes still have two pointers ("references") given that you now know that that the first pointer will always point exactly to the next node. I've see https://github.com/rswier/c4 use that. Granted it doesn't make for the most readable code, but it's even smaller and faster.

vermin_vm: Virtual Machine(~400 lines) + Assembler(~800 lines) written in C
VMs with simple instruction sets is a fun topic. Some years ago I got inspired by the amazing rswier/c4 compiler by Robert Swierczek and explored the smallest instruction set I could get away with to create VMs that could run non-trivial workloads.

Hand-optimizing the TCC code generator
C4 comes to mind (C in 4 functions), https://github.com/rswier/c4.
have you considered adding a backend for LLVM? perhaps a bit heavyweight, but it could be a good way to get C/C++, fortran, rust, etc. if that's something you'd like!

Some people of the Linux Community in a nutshell
I use Alpine Linux (no GNU bloat btw), dwm (Sucks less!), and I edit all my C (no bloat language) through busybox ed and compile my programs with (c4)[https://github.com/rswier/c4]

which programming language was used to make c++ compiler?
Keep in mind you can create a "usable" C compiler by yourself, and is doable in surprisingly low amount of code. Try https://github.com/rswier/c4/blob/master/c4.c
