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.

Is anyone using coroutines seriously?
Yes, with boost.asio and with a self written Qt Networking Coroutine Library like QCoro.

Qt Creator 10 Released
You're not completely wrong, but I think this overstating things by a lot. I'll grant you the containers for example, but you can generally use STL algorithms with them. And plenty of old ways of doing things have left modern Qt-based codebases and moved to more modern ways of doing things, including a fair amount of moc macro usage (and yes, you can remove the moc these days, but it has different perf characteristics - cf. the verdigris project).
The community around Qt is pretty active at adopting modern C++, e.g. imho https://github.com/danvratil/qcoro is leading work.

C++20 coroutines explained simply
I though that with the meager support for coroutines that C++ 20 has, it would take ages till I could use that in Qt, but I discovered that it's actually quite nice with QCoro, which is a 3rd part library that is able to leverage coroutines in Qt's event loop with just an add on. I thought it would require extra facilities in the language/library, plus some large patch to Qt to have the first support of them.

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.
