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.

It's been a while since the latest scala-native update, any news or anybody knows what the devs are working on?
The problem with Scala Native is the fact that it's still a very niche project and does not have a large user base or serious production-level usage. We have only a few libraries which can do with SN things that would not be so easy to do with JVM or Graal Native Image, eg. SNunit . I believe that if the SN would get more traction or some good use-cases in the industry, people would be also more willing to invest more time in the development of that project. In the contrast, Scala.js has already some good commercial usage and nice libraries like Laminar or Airframe RPC

Colima k8s nix setup
What about the docker-cli? colima also ships with a docker-compatible cli to interact with containerd called nerdctl. We can execute the same docker cli commands like:

Nginx Unit – Universal web app server
Using nerdctl: https://github.com/containerd/nerdctl
I'd really disagree that compose files are somehow one-shot, or blindly modified. To the contrary, really, we have them checked in with the source code. Upon deployment to the cluster, the (running) services will be intelligently updated or replaced (in a rolling manner, causing zero downtime). LXC might be more elegant, but I have no idea what simple, file-based format I could use to let engineers describe the environment their app should run in without compose.
I need something that even junior devs can start up with a single command, that can be placed in the VCS along with the code, and that will not require deep Linux knowledge to get running. Open for suggestions here, really.

Jenkins Agents On Kubernetes
Now since Kubernetes works off of containerd I'll be taking a different approach on handling container builds by using nerdctl and the buildkit that comes bundled with it. I'll do this on the amd64 control plane node since it's beefier than my Raspberry Pi workers for handling builds and build related services. Go ahead and download and unpack the latest nerdctl release as of writing (make sure to check the release page in case there's a new one):

Going through a Kubernetes training with autogenerated captions and about half are coming up like this.
That's why nerdctl, their cli binary, is so well named.

Python + containerd? Who might be interested?
Well, it is indeed a good option. However, containerd is a good alternative that is growing even among developers. Please see: https://github.com/containerd/nerdctl

How to own your own Docker Registry address
Nerdctl/containerd has IPFS support :)

DockerHub replacement stratagy and options
nerdctl supports IPFS for both image pulling and pushing, including encrypted images and eStargz lazy pulling. For building, the current method is a locally hosted translator so that the traditional pulls can be converted to work over IPFS. They even have docs on running it on k8s node, though if my reading is correct this isn't exactly a cloud native approach (running systemd services on each node...).
