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.

My resignation letter as R7RS-large chair
Racket is very used in the PLT community (programming language theory) for prototyping programming languages. Lots of cool stuff in this area.
For example, the MIR formality [0] project of the Rust programming language to formalize MIR (their intermediate language) was first prototyped in Racket [1], then rewritten in Rust. [1]'s readme give a rationale:
> For the time being, the model is implemented in PLT Redex. PLT Redex was chosen because it is ridiculously accessible and fun to use. It lets you write down type system rules and operational semantics and then execute them, using a notation that is very similar to what is commonly used in published papers. You can also write collections of unit tests and fuzz your model by generating test programs automatically.
> The hope is that PLT Redex will prove to be a sufficiently accessible tool that many Rust contributors will be able to understand, play with, and extend the model.
> One downside of PLT Redex is that it doesn't scale naturally to performing proofs. We may choose to port the model to another system at some point, or maintain multiple variants.

Why are Rust programs slow to compile?
But MIR optimizations are a bit of a mess right now. The semantics of MIR are not completely settled but that is an area of active work: https://github.com/nikomatsakis/a-mir-formality

Announcing: MiniRust
That's happening separately, in the "mir-formality" project: https://github.com/nikomatsakis/a-mir-formality
The two projects are related, but have different objectives (mir-formality includes traits and borrow checking, while MiniRust focuses on operational semantics).

How to Write a PHP Extension with Zig?
When writing code in a scripting language, sometimes you need that extra bit of performance (or maybe an async feature from Zig).

Bun - The One Tool for All Your JavaScript/Typescript Project's Needs?
NodeJS is by no means a slow runtime, it wouldn’t be so popular if it was. But compared to Bun, it’s slow. Bun was built from the ground up with speed in mind, using both JavascriptCore and Zig. The Bun team spent an enormous amount of time and energy trying to make Bun fast, including lots of profiling, benchmarking, and optimizations.

Bun 1.1
ntdll.dll!RtlUserThreadStart()
There are valid reasons to use APIs from NTDLL. Where I disagree with zig#1840 is the idea that it is always better to use NTDLL versions of API. Every other software ecosystem uses the standard Win32 APIs and diverging from that without a good reason seems like a good way to have unexpected behavior. One concrete example is most users and programmers expect Windows to redirect some file system paths when running on WOW64. But this is implemented in Kernel32, not ntdll.
