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.

From scratch OpenGL and shaders with raw Xlib
I don’t think that exists (I sure would like for it to), but until it does you could amuse yourself with:
- A 500-line (non-OpenGL-compatible) 3D rasterizer: https://github.com/ssloy/tinyrenderer/wiki.
- A “hello Wayland” app written in C without libwayland or anything else: https://gaultier.github.io/blog/wayland_from_scratch.html.
- A “hello X11” app written in x86-64 assembly(!) without libX11, libxcb, or anything else: https://gaultier.github.io/blog/x11_x64.html.

Tiny Compiler – Writing a Compiler in a Weekend
the tinyrenderer[1] project has been on my todos forever now. glad to see the author is writing more self-paced programming projects.

Is there space in this field for extreme cases like mine ?

How do I become a graphics programmer? – A guide from AMD Game Engineering team
There are a couple of excellent resources out there for implementing 3D rendering from scratch.
On that I cannot recommend enough is this github repo:

If you are more of a visual learner, this guy is also a treasure trove:

Ask HN: What books or courses do you know similar to "From Nand to Tetris"?
Other people have mentioned ray-tracing in one weekend
If anyone is really interested in graphics I would also recommend TinyRenderer
https://github.com/ssloy/tinyrenderer/wiki
This one is a CPU-based rasterizing renderer
Its good if you want to get a good understanding of what a GPU does underneath

Trying to learn wgpu
I was in a similar position to you, and I first did this https://github.com/ssloy/tinyrenderer/wiki

Recommendation for graphics experimentation project
Yes, my thoughts exactly, shader!=program on GPU. It's just a code which calculates pixel color or pixel position. See for example this: https://github.com/ssloy/tinyrenderer/blob/master/main.cpp. It's not GLSL or anything uploadable to GPU yet it's still a shader.

I have a few months to prepare for an interview. Is there a project that would get me at least part of the way there for the interview?
In terms of a project which would be worthwhile, I think building a software rasterizer from scratch is a useful first step. TinyRenderer is a great place to start. Looking at the high level overview of many graphics subjects, ScratchAPixel is a valuable resource. Theres also just great information in some of the rote graphics programming textbooks (Michael Abrash's Black Book fully available online from Jason Gregory, and this book is really interesting). The "RayTracer in a weekend" series is also (seemingly) very illuminating (no pun intended).

Thinking Forth: A Language and Philosophy for Solving Problems [pdf]
Cool. Here are some other resources that I've encountered along the way of learning Forth:
- JonesForth: https://github.com/nornagon/jonesforth/blob/master/jonesfort...
This is legit a text that goes the an x86 Forth implementation. Actually, it's just an implementation with really extensive comments. That said, including whitespace and comments, it's just 2000 lines and the pedagogy is excellent. Highly recommended for anyone who would rather see behind the curtain before picking up a larger text.
- SmithForth: https://dacvs.neocities.org/SF/
So, Smith decided to hand-write a Forth directly in x86-64 opcodes (well, the corresponding ascii hex bytes). It's incredibly slim and enlightening how you can bootstrap a language in just a couple hundred bytes or so.
This project actually inspired me to really learn the x86-64 architecture, so I ended up hand-decompiling the SmithForth binary instead of going through his commented implementation. Hand-decompilation is an absolutely fascinating exercise. You learn all about ELF structure, opcode encodings, and actually start to see the gaps where microarchitectural details shine through. Highly recommended for any hacker that really wants to grok low level details.
- Mecrisp: https://mecrisp.sourceforge.net/
An amazingly fast Forth implementation for MSP430, ARM, RISC-V, MIPS, and some FPGAs. This gave me one really nice understanding of Forth as
A REPL into your hardware!

Problem Running JonesFORTH
I've git-cloned JonesFORTH (https://github.com/nornagon/jonesforth/blob/master/jonesforth.S) and achieved to compile it (i.e. run make w/o an error. When I start the executable, it presents me with an empty line, and when I say BYE, it says PARSE ERROR: bye.

Ask HN: Where do I find good code to read?
Is there any particular language you're looking for? I've found some languages hideous until I understood them and could appreciate their respective graces. Off the top of my head the I can think of a couple.
The first is Jones Forth (https://github.com/nornagon/jonesforth), start with jonesforth.S and move into jonesforth.f. I really enjoyed following along with it and trying my hand at making my own stack based language.
The other is Xv6, a teaching operating system from MIT (https://pdos.csail.mit.edu/6.828/2021/xv6.html), not all the code or implementations are top notch but it shows you non-optimized versions (just because they're simple and more readable) of different concepts used in OS design.
If you're interested in the embedded world, there is a really neat project I've been following that feels a more structured and safe (as in fault-tolerant) while still staying pretty simple (both conceptually and in the code itself): Hubris and Humility (https://hubris.oxide.computer/).

Dusk OS: 32-bit Forth OS. Useful during first stage of civilizational collapse
Very low hardware requirements, so basic industrial control at the level where you'd otherwise use an Arduino or so but on scavenged hardware. Forth is ridiculously simple to get an implementation running.
https://github.com/nornagon/jonesforth/blob/master/jonesfort...
Is a nice starting point. It's obviously not as compact as say 'Brainfuck' but it is far more versatile.

Making my own forth implementation
OP mentioned jonesforth, but linked to a nasm port of it. Which is probably good it’s just that the documentation in the comments with ascii art doesn’t look right on my screen. So here’s a more common repo: https://github.com/nornagon/jonesforth

Struggling with looping constructs, BEGIN WHILE REPEAT
Rip the asm macros for the basic FORTH words out of this and then embed them in a C binary, statically linked with your favourite libs for whatever task. Although I haven't tried this yet, I'm planning on doing it with ncurses for my own Roguelike. From there, if you can convert the function calls and your parameters down to raw numbers, you can send instructions to ncurses or whatever other API you like, directly from a FORTH stack.
- I'm wondering why so few forth microcontoller tutorials are out there?
