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.

WASM Instructions
Oh it’s certainly looking like that IMO.
You can run wasm in k8s: https://krustlet.dev/
Docker itself can run wasm: https://wasmlabs.dev/articles/docker-without-containers/
There are a few serverless runtimes based on wasm: https://wasmcloud.com/
A lot of those are powered by wasmtime or WasmEdge.
If you’re wanting to be able to just pull down a random app and run it as wasm, that’s inherently harder with wasm, because you have to recompile, and amazing compiling stuff is always harder than it should be. For example I compiled jq to wasm to other day, so you dont have to worry (as much) about the CVEs that was issued recently. https://github.com/rockwotj/jq-wasi

Crafting container images without Dockerfiles
It can, kubevirt is a project for running VMs https://kubevirt.io/ and there have been more esoteric things like WASM (https://github.com/krustlet/krustlet).

I Don’t wanna use Docker or kubernetes
Or you can run Krustlet instead of Kubelet. That makes it so you can only run WebAssembly on the cluster - so no Go, no Python, only Rust!

Why did the Krustlet project die?
But the project seems to have died: https://github.com/krustlet/krustlet/graphs/contributors

Does anybody have a use-case for Scala WASM compilation target?
There are some cloud providers that are starting to offer wasm support. Docker is currently working on wasm https://docs.docker.com/desktop/wasm/ There is also krustlet https://krustlet.dev/ which lets you run wasm in kubernetes

Are V8 isolates the future of computing?
> If one writes Go or Rust, there are much better ways to run them than targeting WASM
wasm has its place, especially for contained workloads that can be wrapped in its strict capability boundaries (think, file-encoding jobs that shouldn't access anything else but said files: https://news.ycombinator.com/item?id=29112713).
> Containers are still the defacto standard.

Maestro: A Linux-compatible kernel in Rust
Isn't gVisor kind of this as well?
"gVisor is an application kernel for containers. It limits the host kernel surface accessible to the application while still giving the application access to all the features it expects. Unlike most kernels, gVisor does not assume or require a fixed set of physical resources; instead, it leverages existing host kernel functionality and runs as a normal process. In other words, gVisor implements Linux by way of Linux."

Faster Filesystem Access with Directfs
This sort of feels like seeing someone riding a bike and saying: why don’t they just get a car? The simple fact is that containers and VMs are quite different. Whether something uses VMX and friends or not is also a red herring, as gVisor also “rolls it own VMM” [1].

OS in Go? Why Not
There's two major production-ready Go-based operating system(-ish) projects:
- Google's gVisor[1] (a re-implementation of a significant subset of the Linux syscall ABI for isolation, also mentioned in the article)
- USBArmory's Tamago[2] (a single-threaded bare-metal Go runtime for SOCs)
Both of these are security-focused with a clear trade off: sacrifice some performance for memory safe and excellent readability (and auditability). I feel like that's the sweet spot for low-level Go - projects that need memory safety but would rather trade some performance for simplicity.

Tunwg: Expose your Go HTTP servers online with end to end TLS
It uses gVisor to create a TCP/IP stack in userspace, and starts a wireguard interface on it, which the HTTP server from http.Serve listens on. The library will print a URL after startup, where you can access your server. You can create multiple listeners in one binary.

How does go playground work?
The playground compiles the program with GOOS=linux, GOARCH=amd64 and runs the program with gVisor. Detailed documentation is available at the gVisor site.

Multi-tenancy in Kubernetes
You could use a container sandbox like gVisor, light virtual machines as containers (Kata containers, firecracker + containerd) or full virtual machines (virtlet as a CRI).
