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.

Replacing musl's malloc with mimalloc: any ideas?
mimalloc: mimalloc is an open source implementation of malloc, currently the best performing allocator.

Reptar
Some compiler writers thought that was the case, if [0] is related to OP. I don't have a "modern" (after 6th gen) Intel CPU to test it on, but note that most programs are compiled for a relatively generic CPU.

Is the JVM a upside or downside to Scala?
Yes, it's very efficient and that's not where the main problem lies. However, small allocations with modern C heap allocators like mimalloc or snmalloc has gotten extremely efficient as well. Would be interesting to see a benchmark comparison with Java's G1 and ZGC.

Z Garbage Collector: The Next Generation
Memory management for C is not itself a solved problem, not only is there a lot of performance to squeeze out of malloc itself (the benchmarks on https://github.com/microsoft/mimalloc exemplifies the variance between the implementations), but it's up to the programmer to implement memory management in the large in an efficient way, which is not an easy task. One sure mark of a slow C program is one with a ton of mallocs and frees strewn all over.

Linux Tech Tips EP#13: Testing Transparent Huge Pages and Cryo Utilities in Gaming | 3700X 6600XT
It's a very terse howto for replacing Factorio's memory allocator with Microsoft's mimalloc, and configuring mimalloc so that memory is always allocated on huge pages by using madvise().

Differences between Lean4 and Koka reference counting
I was wondering if Koka's perceus referencing counting style is any different from the reference counting that Lean4 implements? I understand that both rely upon the mimalloc (https://github.com/microsoft/mimalloc) library in the backend.

pmr implementation in c++14
If you are fine with heap allocations then there are only few dozens operator new/delete to override to regain control over normal C++ code memory use. Allocators and STL all need to call those. At least that's what gaming does on all platforms. If you need examples you can check Mimalloc on github ( https://github.com/microsoft/mimalloc/blob/master/include/mimalloc-new-delete.h ).

What are some cool modern libraries you enjoy using?
I love: https://github.com/boost-ext/di for dependency injection

[C++20] New way of meta-programming?

Dependency injection
I was looking to try boost.di for some time, looks nice. https://boost-ext.github.io/di/
- Dependency injection with c++
-
Architecture of a Qt application
Things like Dependency Injection/Inversion are a little more cumbersome in C++ but certainly can be done, and I believe there's libraries for that as well (found a couple searching around, like fruit and boost-ext di ).

Jodd – The Unbearable Lightness of Java
Dependency injection does not have to be dynamic, it can totally be done at compile time. Boost DI is an example: https://boost-ext.github.io/di/
- DI in c++ hurt by lack of good libraries?

Top five C/C++ things/tips/tricks you wish you had known earlier and are now used very often
Funny you mention dependency injection, proposed Boost.DI shall be up for Boost peer review probably in March. https://boost-ext.github.io/di/
