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: Error return traces for Go, inspired by Zig
The README covers the idea behind errtrace in more details, but the primary difference is in what is captured:
pkg/errors captures a stack trace of when the error occurred, and attaches it to the error. This information doesn't change as the error moves through the program.
errtrace captures a 'return trace'--every 'return' statement that the error passes through. This information is appended to at each return site.
This gives you a different view of the code path: the stack trace is the path that led to the error, while the return trace is the path that the error took to get to the user.
The difference is significant because in Go, errors are just plain values that you can store in a struct, pass between goroutines etc. When the error passes to another goroutine, the stack trace from the original goroutine can become less useful in debugging the root cause of the error.
As an example, the [Try it out](https://github.com/bracesdev/errtrace/#try-it-out) section in the README includes an example of a semi-realistic program comparing the stack trace and the return trace for the same failure.

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.

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.
