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.

Micro Beast: Self contained 8-bit computer kit in a box
http://collapseos.org/
I know the point of it isn't to run on new hardware, but this would be a way to learn it on a stable platform without having to worry about dealing with constant problems from old hardware before trying to implement it on said.

Ask HN: We should urge law makers to unlock the bootloaders
There is something called Collapse OS I read about here on HN:
http://collapseos.org/
I myself am a collector of old devices, having raised three kids plus being a web dev. Hate throwing them away too I was just think about this today could I extract the CPUs or RAM or something to reuse rather than destory for the metals. I'd like to learn more hardware but no time.

Need help with designing a basic RISC V processor?
Maybe start with sufficient support for a simple OS that allows you to edit and compile programs. Something like FreeDOS or CollapseOs. Once you have that working you can extend it.

Subreddit Updates: May 2023
During collapse we'll all be using Dusk OS and post collapse we'll be using cobbled together rugged computers running on Collapse OS. I imagine at that point we can probably put the sub name to a vote. Maybe "r/ordinarylife".

A ultra minimalist distro just for fun
Not Linux....but you could just install Kolibri OS for a very light desktop or consider CollapseOS and DuskOS....think Dusk should run bare metal on now and won't be too bloated, but there's always CollapseOS if you prefer to keep things light

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?
