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.

A decade of developing a programming language
I'm in the same boat as you -- here are the two best resources I found:
https://mukulrathi.com/create-your-own-programming-language/...
https://jaked.org/blog/2021-09-07-Reconstructing-TypeScript-...
I read through the first 10 chapters of TAPL, and skimmed the rest. The first 10 chapters were good to remind myself of the framing. But as far as I can tell, all the stuff I care about is stuffed into one chapter (chapter 11 I think), and the rest isn't that relevant (type inference stuff that is not mainstream AFAIK)
This is also good:
https://github.com/golang/example/blob/master/gotypes/README...
And yeah I think we had the same conversation on Reddit -- somebody needs to make a Crafting Interpreters for type checking :) Preferably with OOP and functional and nominal/structural.

Slog: Zero-dependency structured logging in Go
A guide covering how to write custom handlers is out of scope for this post, but you can find one such guide written by the author of slog here. Thankfully, you don’t need to write a handler from scratch to use one. There are several community-contributed handlers, including handlers that allow you to output colored logs, and a handler that lets you implement sampling. You can find a full list here.

[blog post] Ten challenges for Rust
I am not too familiar with how Go does things, but it, eg, exposes Go type-checker via stdlib: https://github.com/golang/example/tree/master/gotypes. Similarly, I believe gofmt uses the ast package from stdlib, rather private compiler internals like rustfmt.

Can't get gopls to work with nvim-lsp
So I just cloned this git repo https://github.com/golang/example and as soon as I entered the hello/hello.go file I was able to get autocomplete and error checking. I don't understand why it isn't working with just a .go file I made.

I'm not sure where to begin. I find programming exhausting.

Memories: Edinburgh ML to Standard ML
2. Preservation states that if you have a program that type-checks _and_ that can continue evaluating, _as_ it continues to evaluate, it _continues_ to type-check.
Note that the conclusion of preservation 'feeds back' into progress: the program type-checks. And vice versa: progress may state as its conclusion that the program can continue evaluating, which then lets you apply preservation. This means you can keep applying the progress and preservation theorems in a 'loop' until the program is done evaluating.
For each of the 4 posts in my series about formal semantics, I duly translated the rules presented in the blog post into Lean code, and then proved that the rules do satisfy the safety properties. For example, for the first post linked above:
