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.

Have questions/requests/issues related to the Zig Language Server?
There is no official documentation but the standard library provides definitions for the exchange format and an incomplete set of function for exchanging messages in Client.zig and Server.zig. You can find examples of the zig compile server in action in my PR for ZLS and a showcase of hot-code-swapping by kubkon. The code that implements the ZCS in the zig codebase can be found here.

Question about zls
Same experience here, I did file a bug about it too: https://github.com/zigtools/zls/issues/1139

Lack of instructions on using IDEs to start playing with Zig
Welcome to the word of new languages, I think rust just got an intellij plugin late last year and its been in 1.0 since 2015 (not to mention the years of hype around it). When it comes to "non standard" languages (meaning not the industries current go to for a given niche), it helps to assume there's no "It's just works" type editor support. Luckily most languages, even new ones have LSP servers including zig, and editors like VSCode make it pretty simple to use them.

Allow download in build flake's build phase.
For the people who come in the future and want to know how to do it, here is the code as of today (at some point it will be in ZLS repository - github.com/zigtools/zls - and you should take a look there too to see more up-to-date code).

Failing to Learn Zig via Advent of Code
> Building is slow. It takes about ~3 seconds minimum which is frustratingly slow when I'm fighting basic syntax errors. I wish there was a fast zig check.
> Lack of zig-analyzer makes learning hard.
> zig fmt src/main.zig is nice. Wish it automatically ran on all files.
I also did (well, "am doing", can only work a bit each day and am plugging through day 7 right now) AdventOfCode in Zig this year.
These points here didn't resonate with me at all. I wonder if the author knew about or tried ZLS[0]. I had it on and integrated with my VSCode and it would check a lot of things as I went and format on save. I think I followed something like this[1] to set it up.

How in the world do you set up nvim-cmp?
cd $HOME/.local/zls && curl -L https://github.com/zigtools/zls/releases/download/0.9.0/x86_64-macos.tar.xz | tar -xJ --strip-components=1 -C .

Why do lifetimes need to be leaky?
No, you don't. Existential proof: mrustc ignores lifetimes. Just flat out simply ignores. It changes some corner-cases related to HRBT, yet rustc compiled by mrustc works (that's BTW mrustc exist: to bootsrap the rustc compiler).

I think C++ is still a desirable coding platform compared to Rust
Incidentally C++ is the only way to bootstrap rust without rust today.

Rust – Faster compilation with the parallel front-end in nightly
Well, there is mrustc[0], a Rust compiler that doesn't include a borrow-checker, so it's possible to compile (at least some versions of) Rust without a borrow checker, though it might not result in the most optimized code.
AFAIK there are some optimization like the infamous `noalias` optimization (which took several tries to get turned on[1]) that uses information established during borrow checking.
I'm also not sure what the relation with NLL (non-lexical lifetimes) is, where I would assume you would need at least a primitive borrow-checker to establish some information that the backend might be interested in. Then again, mrustc compiles Rust versions that have NLL features without a borrow-checker, so it's again probably more on the optimization side than being essential.

Forty years of GNU and the free software movement
> Maybe another memory safe language, but Rust has severe bootstrapping issues which is a hard sell for distros that care about source to binary transparency.
It is possible to bootstrap rustc from just GCC relatively easily, although it's a little bit time consuming.
You can use mrustc to bootstrap Rust 1.54: https://github.com/thepowersgang/mrustc
And from then you can go through each version all the way to the current 1.72. (Each new Rust version officially needs the previous one to compile.)

Stop Comparing Rust to Old C++
There are three. The official one, mrustc (no borrow checker, but can essentially compile the official rustc) and GCC (can't really compile anything substantial yet). Only rustc is production-ready though.

Can I make it so that only the newest version of Rust gets installed?
That probably depends on what you mean by problematic. Having an ever increasing chain of dependencies isn’t the most desirable situation so there has been some work to trim the bootstrap chain. In 2018, when the blogpost I linked above was written, mrustc was used to bootstrap rust 1.19.0; now mrustc can bootstrap rust 1.54.0 so the chain to recent versions is much shorter than if all those intervening versions back through 1.19.0 needed to be built. https://github.com/thepowersgang/mrustc
