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 run an Nginx container with socket activation and rootless Podman? (I only got it working with a simplified Nginx container image)
Socket activation should be the fastest alternative as then there is no need to process and interpret the network traffic that is sent over the socket. Both slirp4netns and netavark process the traffic. If I understand correctly the network driver bypass4netns could have similar performance as socket activation. The current bypass4netns implementation has some security problems but it seems that could be fixed.

Podman 4.2.0
(That could a be cool feature)
Also interesting would be to fix the security considerations of using bypass4netns:
"However, it is probably possible to connect to host loopback IPs by exploiting TOCTOU of struct sockaddr * pointers."
There seems to be an implementation idea for how the problem could be fixed:

Minikube now supports rootless podman driver for running Kubernetes
The filesystem performance degradation was resolved in kernel 5.11 which added support for rootless overlayfs.
The network performance is caused by slirp (usermode TCP/IP) but it is being resolved too : https://github.com/rootless-containers/bypass4netns

A gopher’s journey to the center of container images
For the task of building the graph image, my first idea was to rely on buildah. In fact, our design was already heavily relying on containers/image for all things regarding copying images from one registry to the other, or from one registry to an archive. The obvious choice was to use the same suite of modules in order to keep dependencies to a minimum.

Podman Desktop for Java Development
I appreciate that podman can run daemonless, but I've gotten tired of waiting for them to implement heredoc support and have continued to use docker.

How to use Podman inside of a container
You do realize that, under the hood, buildah uses a container engine (runc by default)? See https://github.com/containers/buildah/blob/main/docs/buildah...

Podman v4.4, Buildah v1.29 released!
Last week, Buildah version 1.29 was also released. The prune command has been added to clean intermediate images as well as the build and mount cache. Support for the –group-add option to the from and build commands was added. One useful feature of this, it to use the –group-add keep-groups option, which allows rootless users to take advantage of their group access to file and devices mounted into the build containers. And the –cache-from and –cache-to options for the build command now allow for multiple sources. This can be used to improve the speed of builds, especially in CI/CD environments.

Rails on Docker · Fly
Unfortunately this syntax is not generally supported yet - it's only supported with the buildkit backend and only landed in the 1.3 "labs" release. It was moved to stable in early 2022 (see https://github.com/moby/buildkit/issues/2574), so that seems to be better, but I think may still require a syntax directive to enable.
Many other dockerfile build tools still don't support it, e.g. buildah (see https://github.com/containers/buildah/issues/3474)
Useful now if you have control over the environment your images are being built in, but I'm excited to the future where it's commonplace!
