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.

Show HN: Regex Derivatives (Brzozowski Derivatives)
I don't think Rust regex engine relies on this technique. I guess the main point is when you construct the DFA directly you still have the possibility of the exponential explosion of the number of states. That's why modern engines balance between NFA/DFA and lazy DFA.
Though there is an implementation that relies only on Brzozowski derivatives: https://github.com/google/redgrep

Introducing: Pomsky (formerly Rulex)
redgrep did it though: https://github.com/google/redgrep
- Redgrep – grep based on regex derivatives, matches in linear time

Speed of Rust vs. C
It couldn't figure it out from looking through ripgrep's website: does ripgrep support intersection and complement of expressions? Like eg https://github.com/google/redgrep does.
Regular languages are closed under those operations after all.

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.
