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.

Any standard algorithms for parsing (disassembling) machine code?
BAP (https://github.com/binaryanalysisplatform/bap), angr (https://angr.io/) and others already do what you're asking for as more purpose-built solutions for dynamic analysis. Angr specifically in python.

Starting ocaml
I find this pretty good https://www.cs.cornell.edu/courses/cs3110/2019sp/textbook/intro/ocaml.html. Fun projects include compilers (pattern matching and static types are why Ocaml is usually selected), binary analysis stuff https://github.com/BinaryAnalysisPlatform/bap, stuff that requires async so you can try out nomadic async stuff, or really anything you desire.

Zero Knowledge FPGAs
title: Accelerating zk-SNARKs - MSM and NTT algorithms on FPGAs with Hardcaml
Any reason the title deviates so much from original? Is it because of all the cool acronyms and code words? Here's a decoder:
zk-SNARK: zero-knowledge Succinct Non-Interactive Argument of Knowledge
MSM: Multi-Scalar Multiplication
Hardcaml: OCaml lib for hardware: https://github.com/janestreet/hardcaml
NTT: Number Theoretic Transform

A circuit simulator that doesn't look like it was made in 2003
Perhaps peripheral (the original site has been hugged to death).
Both clashlang: https://clash-lang.org/
And Hardcaml: https://github.com/janestreet/hardcaml
have personally fueled my interest in hardware.
Dan Luu speaks eloquently and at length about how better options are needed for logic design. I would recommend both of the above to the enthusiastic novice.

HRT or Jane Street?
Join JS and you can program FPGAs in a strongly typed, expressive, high level programming language (OCaml): https://github.com/janestreet/hardcaml

Designing a MIPS CPU in Hardcaml (12 part series)
> You can put all the functions/tasks you want in that module.
Coming from a software background, the testing strategies available in Verilog seem very clunky and overly verbose. In comparison, Hardcaml's ASCII waveform expect-test solution feels extremely elegant and simple: https://blog.janestreet.com/using-ascii-waveforms-to-test-ha....
> And all of my development and that of my team happens through gitlab-CI.
That's probably more of a gap in my education than a fault of the ecosystem then.

Among other qualities, I prefer languages that let fewer mistakes slip through, and allow the developer to focus on the system they intend to build rather than avoiding bugs/misunderstandings that would be easy to catch otherwise. You bring up a lot of really good points, and I suspect that if we were doing Verilog "the right way", we would have probably run into fewer issues. But at the end of the day, developing in Hardcaml was a much more ergonomic experience: testing was straightforward, most "stupid mistakes" were impossible, setup was pretty easy, and the library provided a lot of really useful abstractions. For example, Hardcaml interfaces make it easy to represent practically any data structure that can be serialized to/from a bit vector, and the Always API allows for some pretty interesting non-trivial functional logic.

Hardcaml MIPS CPU Learning Project and Blog
A few months ago, I came across the Signals and Threads Programmable Hardware episode. I really liked the idea of Hardcaml: a library to write and test hardware designs in OCaml. Representing circuits as functions felt like a good abstraction, and I’ve been wanting to learn OCaml for a while.
