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.

- Running the "Reflections on Trusting Trust" Compiler
- stage0 x86 seed reduced from 357 Bytes to 256 Bytes

test
From here I found a reference to the Gash, Mes-M2 and stage0 projects, who's README.org references a nice wiki for stage0. The Wiki references a more expansive stage0-posix repo. From here, I finally got all the pieces to fit togeather.

How reproducible are Guix packages?
Of course, reproducible builds will only give you security if you trust the compiler you're using to verify. Unlike traditional distributions, Guix packages are rigorously defined in terms of their dependencies all the way down to ~60 MB of bootstrap binaries. There has been a lot of cool work to reduce the initial binary seed size, and they are working to reduce this even further to a "full source" bootstrap which will make use of the stage0 project to bootstrap the entire OS from a small, auditable ASCII Hex -> binary program.

stage0-posix was ported to RISC-V
stage0-posix just gained initial support for RISC-V (64-bit). It starts with 392 byte hex assembler, 361 byte "shell" and bootstraps simple linker (hex2), macro assembler (M0). Then it builds cc_riscv64 RISC-V compiler written in RISC-V assembly and uses it to build simple C compiler written in C (M2-Planet). Then it builds a few extra utilities (cp, mkdir, untar, ungz, sha256sum, chmod)

Bootstrapping from Hex to Bison to GCC
I wonder if Brainfuck could be used for https://github.com/oriansj/stage0-posix ? It would not surprise me if there is no other language for which there are so many interpreters written in so many different programming languages. It is even possible to write a Brainfuck interpreter in Brainfuck, which can be verified. And there is also a Brainfuck interpreter written in x86-64: https://github.com/316k/brainfuck-x86-64 . It is a little larger than hex0_x86.hex0 , but not too much to make it hard to verify.

A Brief Introduction to Forth (1993)
I'd argue the easiest to implement language is macro-assembly then the C subset known as cc_x86
