The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Anon knows programming
And having run across jonesForth (https://github.com/organix/pijFORTHos/tree/master/annexia read the .s file and then the .f file) and basically the idea of building your own personal software stack from scratch, but part of the problem is just having hardware that wasn’t designed to be super complicated to interface with (like USB being much more complicated than PS/2 or wiring up your own grid of switches for a keyboard).

Jonesforth – A sometimes minimal FORTH compiler and tutorial (2007)
I want to write one for bare metal (non-Linux) raspberry pi (ARMv6 32 bit on Raspberry Pi 1 and Zero; ARMv7 and ARMv8 on higher models and also supports 64 bit). I want to have no dependencies required though so was thinking of bootstrapping it with nothing but machine code (determined initially with the help of an assembler and documentation of course). Someone has already ported jonesforth the Raspberry Pi[1] but using serial i/o as the user interface and it has dependecies to build it, but I should be able to get ideas from how they coded their assembly parts compared to the original jonesforth. I want to be able to use HDMI for the screen (already tried it out with some bare metal tutorials in assembly so that's do-able) and again, with no dependencies. And I want to show people how to do it themselves, not just have it be something to run that they don't understand fully. It should also be possible to have the forth kernel build/assemble itself if needed, or cross-target another platform.
I know I'm all talk right now, like you say, I need to manage my free time so that I would have the "copious free time" to work on this.

Jonesforth – A sometimes minimal FORTH compiler and tutorial (2007)
It was a lot of fun for me to reimplement this in MIPS assembler on CI20 [0]
JonesForth could be more straightforward in its interpreter part. I tried to make this part as clean as possible, hopefully did not miss anything.
Maybe I will make a RISCV version in my copious free time in the future.

Ask HN: What are some interesting examples of Prolog?
Not exactly a big codebase, but it was a revelation for me how natural typecheckers can feel in Prolog: I basically rewrote typing rules with some tweaks: [1]
Also, tests were surprisingly enjoyable in Prolog: [2].
