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

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

Unlocking the Power of WebAssembly
WebAssembly is extremely portable. WebAssembly runs on: all major web browsers, V8 runtimes like Node.js, and independent Wasm runtimes like Wasmtime, Lucet, and Wasmer.

Show HN: dockerc – Docker image to static executable "compiler"
Unfortunately cosmopolitan wouldn't work for dockerc. Cosmopolitan works as long as you only use it but container runtimes require additional features. Also containers contain arbitrary executables so not sure how that would work either...
As for WASM, this is already possible using container2wasm[0] and wasmer[1]'s ability to generate static binaries.

Howto: WASM runtimes in Docker / Colima
I could not find any guide how to add WASM container capability to Docker running on Colima. This guide provides a few Colima templates for exactly this, which adds WasmEdge, Wasmtime and Wasmer runtime types.

Prettier $20k Bounty was Claimed
The Biome team has been incredibly fast on solving the challenge and achieving 95% compatibility with Prettier [1]
Just as a note, as it was not mentioned in the article, Wasmer [2] also participated with a $2,500 bounty to compile Biome to WASIX [3], and it has been awesome to see how their team has been working to achieve this as well... hopefully we'll get Biome running in Wasmer soon!
Keep up the great work!!

The Curse of Docker
It's funny how WebAssembly can help overcome most of the issues mentioned on the blogpost (packaging, configuration, portability) if addressed properly.
That's the main reason Wasmer [1] was created :)
