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.

Show HN: dockerc – Docker image to static executable "compiler"
Yep pretty much.
The executables bundle crun (a container runtime)[0], and a fuse implementation of squashfs and overlayfs. Appended to that is a squashfs of the image.
At runtime the squashfs and overlayfs are mounted and the container is started.

Google assigns a CVE for libwebp and gives it a 10.0 score
On this note, I was really surprised to find Red Hat's OCI runtime is written in C: https://github.com/containers/crun
Is anyone working on a Rust version?

US Cybersecurity: The Urgent Need for Memory Safety in Software Products
It's interesting that, in light of things like this, you still see large software companies adding support for new components written in non-memory safe languages (e.g. C)
As an example Red Hat OpenShift added support for crun(https://github.com/containers/crun) this year(https://cloud.redhat.com/blog/whats-new-in-red-hat-openshift...), which is written in C as an alternative to runc, which is written in Go(https://github.com/opencontainers/runc)...

Crun: Fast and lightweight OCI runtime and C library for running containers
Kubernetes needs an OCI runtime to run containers with. Crun is one implementation it can use.
Docker also appears to be able to use crun for it's engine as well. https://github.com/containers/crun/issues/37

- Why did the Krustlet project die?

Is this an incompatibility with docker or an I doing something else wrong?
Looks like https://github.com/containers/crun/issues/255 - start there.

Kubernetes for Developers
There are ton of optimizations that could be applied to kubernetes itself, including some custom CRI's (youki cri etc), read-only fs handling (erofs etc), and stacked CNI's on top of SR-IOV and Multus. Gluing it all together can be a real pain.
- Youki v0.1.0, a container runtime in Rust that can be used with K8s is available

Crun: Fast and lightweight OCI runtime and C library for running containers
Looks like there is youki [1] for that.
