Our great sponsors
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.

Fuzzing ping(8) and finding a 24 year old bug
Below is the small framework we use to fuzz a network client. It works by creating a Unix socket, forking, then having the client (under test) on one side of the socket and a small loop which reads the input file into the socket on the other side.

The fastest way to copy a file
We did a bunch of benchmarking around this when writing nbdcopy (https://gitlab.com/nbdkit/libnbd/-/tree/master/copy) which can copy file to file as well as between local files and NBD servers. There was also the goal to avoid polluting the page cache, which depending on if you're going to use the file content immediately afterwards or not matters.
Anyway long story short, the best thing we found (for Linux) was Linus's own advice linked from here: https://stackoverflow.com/a/3756466
- A 100LOC C impl of memset, that is faster than glibc's
What are some alternatives?
dattobd - kernel module for taking block-level snapshots and incremental backups of Linux block devices
rsl - reserialise: lossy but versatile conversion between data serialisation formats
qemu
jackson-jq - jq for Jackson Java JSON Processor
transgui - 🧲 A feature rich cross platform Transmission BitTorrent client. Faster and has more functionality than the built-in web GUI.
memset_benchmark - This repository contains high-performance implementations of memset and memcpy in assembly.
safeclib - safec libc extension with all C11 Annex K functions
git-filter-repo - Quickly rewrite git repository history (filter-branch replacement)
cppiceberg - The C++ Iceberg
bfg-repo-cleaner - Removes large or troublesome blobs like git-filter-branch does, but faster. And written in Scala
