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.

how to rsync from a docker container to my host computer
Everything is working fine, but it is not currently doing the automatic code reload. I tried mounting the volume but there is some conflict with the way docker and virtualbox handles files such that the conflict leads to file changes from the host not reflected in docker container. (That's not the first link I have that appears related to this problem, it's just the first I found while googling it on another day)...

Why does Moby have so many stars on GitHub?
Moby is the core of Docker. https://github.com/docker/docker redirects to it.

Moving from IPV4 to IPV6 for my home server
Docker however has made some major screwups in their IPv6 implementation, so it’s not so trivial as you’d expect it to be. There’s a whole discussion about it here: https://github.com/docker/docker.github.io/issues/6075 but the gist is: Docker cannot auto-assign addresses (SLAAC) like a normal endpoint, it also cannot request a prefix (DHCPv6 PD) like a router, you have to set it all up manually.

Why docker swarm is not popular as Kubernetes?
That said, Swarm is definitely in maintenance mode, which is actually how some people like it, given that this means pretty good stability for the current features, instead of breaking changes, which are a slightly larger concern in the case of Kubernetes. However, this also means that new features will get implemented only occasionally, if ever - the last big one that i recall was Swarm jobs. Essentially, i'd say that it's still just a question of time until Swarm dies, but for now it's in the sweet spot of stability and usability if all that you need is a pretty simple and lightweight orchestrator.

Confused about how disk-space usage works with overlay2
From scrounging through the internet, my understanding is if multiple docker containers are run based on the same image, the only extra disk space used is what the writable layer uses and the read-only image data is shared by all the containers. https://github.com/docker/docker.github.io/issues/1520#issuecomment-305179362

Please don't upgrade Docker without asking first
Wowww: https://github.com/docker/docker.github.io/issues/6910#issue...
What the hell does "Docker's new direction to go back to its roots and focus on developer tooling" even mean? Docker is developer tooling, that's the whole product. That's not "going back to your roots" that's just doing your damn job.

Release Radar • March 2024 Edition
Having been featured in our February 2023, and January 2024 Release Radars, Moby is the original Linux Container runtime. This new version adds a bunch of changes to the Docker CLI and Moby itself with additional features. There's bug fixes and enhancements, with the main thing for users to be on the look out for containers that were created using Docker Engine 25.0.0. These containers might have duplicate MAC addresses, and thus must be recreated. The same goes for those containers created with Moby 25.0+ and with user defined MAC addresses. Read up on all these changes in the release notes.

Choosing a Name for Your Computer
Formlabs does this as well for their 3d printers, my earliest encounter of this was when Docker started getting popular: https://github.com/moby/moby/blob/master/pkg/namesgenerator/...

Do not install Docker Desktop on GNU/Linux systems
Try to use moby instead since that is the engine in Docker.

Exploring Podman: A More Secure Docker Alternative
> Podman is designed to help with this by providing stronger default security settings compared to Docker. Features like rootless containers, user namespaces, and seccomp profiles, while available in Docker, aren't enabled by default and often require extra setup.
Seccomp has been enabled by default since 2015: https://github.com/moby/moby/pull/18780
It is true that Rootless isn't enabled by default but its "extra setup" can be done with a single command (`dockerd-rootless-setuptool.sh install`)

OpenZFS 2.2: Block Cloning, Linux Containers, BLAKE3
Perhaps.
Thing is, https://github.com/moby/moby/blob/670bc0a46c4ca03b75f1e72f73... is using https://github.com/mistifyio/go-zfs which features code like `out, err := zfsOutput("get", "-H", key, d.Name)` (Source: https://github.com/mistifyio/go-zfs/blob/master/zfs.go#L315) to get a single zfs property.
Somebody chose to use a library as abstraction that looks good but is implemented as a MVP (nothing wrong with that). "In the future, we hope to work directly with libzfs" should have raised an alarm somewhere, though.
