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.

Zig 0.9.0
> it cannot leave the input data as an undecoded bag of bytes
But all it's doing here is taking a hex string (which is entirely ASCII) and converting it into the respective hex representation. Since ASCII translates unambiguously to bytes, it doesn't really matter if `str[0]` is operating on a byte stream, codepoint stream or grapheme stream, because in utf8, they're all the same thing as long as we're within the ASCII range.
Where things get hairy is stuff like `str.reverse()` over arbitrary strings that may or may not be in ASCII. This repo[0] talks about some of the challenges associated with conflating characters with either bytes or codepoints. The problem is that programming languages often approach strings from the wrong angle: you can't just tack on handling of multi-byte codepoints on top of ascii handling; you lose O(1) random access and you don't actually model the linguistic domain properly by doing so, because in the first place, humans think of characters not in terms of bytes or codepoints, but in terms of grapheme clusters. Clustering correctness falls deep in the realm of linguistics, and is therefore arguably more suitable to be handled by a library than a programming language.

Awesome javascript one-liners to look like a pro
Here's a take on the first snippet (string reversal) by Mathias Bynens (Staff engineer at Google): https://github.com/mathiasbynens/esrever . If you read that README you'll quickly realize that readability of the code isn't all that high in the list of priorities: making it work correctly in the first place is actually a huge can of worms!

Show HN: I made a better Perplexity for developers
It's "Zig" not "Zag". https://ziglang.org/ Zig is under heavy development, but there's a single page https://ziglang.org/documentation/0.12.0/ that is a reasonably comprehensive source of truth about the current state of the language.

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.
