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.

Why AWS Supports Valkey
This is correct, but doesn't quite explain why. It's because when you accept contributions from a variety of authors, without using a CLA, then your code base ends up with a patchwork of copyright, making relicensing practically impossible as you have to get buy-in from every author or else determine that author's contributions and remove/rewrite them.
GPL/LGPL are excellent licenses, but this patchwork of copyright can apply for any license you use. For a small project we wrote which was under BSD, we recently had to make a small (non-functional) change to the license, and we got buy-in from all the authors to do this which took quite a long time: https://gitlab.com/nbdkit/nbdkit/-/commit/952ffe0fc7685ea775...

The C++20 Naughty and Nice List for Game Devs
I think an exception might be made for a plain "C-like" struct that doesn't initialize members or contain anything except basic types. In the specific example[0] the code is actually surrounded by extern "C" { ... } so I suppose that the compiler "knows" this is a plain C struct?

The OpenTF Manifesto
We relicensed[1] a project which had 10 contributors, and we got every single one of them to do an Acked-by (by email) which took some weeks. That was the advice from our lawyers. Can't imagine the impossible hassle of doing the same for something like Linux.

Function multi-versioning in GCC 6 (2016)
mem* do not need to be called via ifunc. That is a toolchain decision. See e.g. https://github.com/nadavrot/memset_benchmark for recent data about the cost of PLT indirection for small copies.

A 100LOC C impl of memset, that is faster than glibc's
Probably poorly. It is a violation to cast an unaligned pointer to an aligned type. And the code looks like it does just that right here: https://github.com/nadavrot/memset_benchmark/blob/main/src/l...
This is undefined behavior under C99 §6.3.2.3 Paragraph 7.

A faster implementation of memset in 100 LOC
I was impressed by the notion until I saw the code...
What are some alternatives?
dattobd - kernel module for taking block-level snapshots and incremental backups of Linux block devices
safeclib - safec libc extension with all C11 Annex K functions
libnbd
gcc
qemu
fancy-memset - small, fast memset based on microsoft's design
transgui - 🧲 A feature rich cross platform Transmission BitTorrent client. Faster and has more functionality than the built-in web GUI.
jackson-jq - jq for Jackson Java JSON Processor
git-filter-repo - Quickly rewrite git repository history (filter-branch replacement)
llvm-project - The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
