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

[SSP] Assembly is of course nice, but not always practical. For those interested in a compact, embeddable and portable little Forth written in C, take a peek at zForth: https://github.com/zevv/zForth.

Forth for embedded use
Thanks. I've since also found zForth, which looks like it meets that particular requirement, though I've not tried it out myself yet. Has anyone had any useful experience with this?
