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.

Python cruising on back of c++
The parent comment is referring to the primary Python interpreter and runtime, CPython, not to libraries. There are of course other Python implementations, but [the only C++ one](https://github.com/tekknolagi/skybison appears to be unsupported.

Faster CPython at PyCon, part one
Kind of! In my fork I run microbenchmarks on each PR. So you can see on, for example, https://github.com/tekknolagi/skybison/pull/456, that the change had a 3.6% improvement on the compilation benchmark. If you expand further, you can see a comparison with CPython 3.8. Unfortunately Skybison is still on 3.8.

Another NaN-based tagging strategy for dynamic programming languages
This is also the pointer tagging scheme from the Ghuloum paper. I did not design it. Another tagging scheme I did not design is the Skybison scheme, which uses 0bXXX...XX0 to tag integers and 0bXXX...001 to tag heap pointers. This makes heap reads very easy (bias by -1 in addressing mode).

wrench (tiny, fast, c-like interpreter): created a webpage and now looking for benchmark code
Skybison is a Python interpreter and I'm curious what the results look like. We also have some benchmarks in benchmarks/benchmarks.

Using Firecracker and Go to run short-lived, untrusted code execution jobs
If you take a look at the Skybison Python runtime, I would be happy to chat and help you poke around integrating it: https://github.com/tekknolagi/skybison

November 2021 monthly "What are you working on?" thread
I am, in fits and starts, writing a bytecode optimizer for Skybison that takes advantage of type information.

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).
What are some alternatives?
RustScript2 - RustScript is a functional scripting language with as much relation to Rust as Javascript has to Java.
firecracker - Secure and fast microVMs for serverless computing.
lockdown - Lockdown is a general-purpose programming language that combines the positive characteristics of both "strongly-typed" and "dynamic" languages, giving the developer the choice about when and how these should be used.
podman - Podman: A tool for managing OCI containers and pods.
cib - clang running in browser (wasm)
wsl-vpnkit - Provides network connectivity to WSL 2 when blocked by VPN
aussieplusplus - Programming language from down under
kata-containers - Kata Containers is an open source project and community working to build a standard implementation of lightweight Virtual Machines (VMs) that feel and perform like containers, but provide the workload isolation and security advantages of VMs. https://katacontainers.io/
Generic-C-DataStructures - A repository for code I wrote while learning to implement generic data structures in C
sysbox - An open-source, next-generation "runc" that empowers rootless containers to run workloads such as Systemd, Docker, Kubernetes, just like VMs.
tonic - An elegant language for script-kiddies and terminal squatters.
containerd - An open and reliable container runtime
