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.

The Zen of Forth
Forth also requires very minimal resources to implement which can be fun in constrained environments. Here it is on a TI-84+ calculator[0] or even a computer in The Powder Toy.[1]
The runtime design is a little quirky but straightforward and you can extend the system as you execute (or even change interpreter semantics), or add optimizations such as some form of JIT quite easily.

Jonesforth – A sometimes minimal FORTH compiler and tutorial (2007)
Some time ago I wrote an implementation of Forth that runs on the TI-84+ and TI-83+ calculators directly inspired by Jonesforth.[0] It runs under TI-OS as well, but the amount of available space is somewhat limited. On another implementation I wrote[1] you have full access to the calculator hardware and memory from Forth.

TI-84 Plus CE Python Graphing Calculator
On the TI-84+, assembly programs still work and it's still a test-approved device. I wrote a Forth interpreter[0] that can interop with the syscalls as well

Late 70s and 80s: forget BASIC, we had Pascal and C
Something bespoke.
My code repository contains a link to a youtube channel where the board was discussed, and where I found it randomly. But sadly the upstream site of the provider and the (useful) forums it hosted are gone unless you use the wayback machine:

Turbo Pascal Turns 40
That's what I remember too.
I briefly documented how to run Turbo Pascal 3.00A on a CP/M system a while back:
https://github.com/skx/z80-playground-cpm-fat/blob/main/TURB...
I'm doing that on a single-board Z80-based system, and it has to be said that writing pascal is a pleasure on such a machine. 64k of memory, and yet code compiles to real executables "instantly".
