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.

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.

Taking a deep dive into C++ gave me more appreciation for Go's simplicity
I've been keeping an eye on TinyGo (Go compiler that targets microcontrollers and uses LLVM) and also TamaGo (allows you to run Go on bare metal, without any C dependency).

ISO C became unusable for operating systems development
> just proves your lack of knowledge
Tone is not needed.
For TamaGo, it seems to allow developers run their application, not build an OS on the hardware. But I have not played with it, you are right.
> TamaGo is a framework that enables compilation and execution of unencumbered Go applications on bare metal
The environment does not seem to allow building a generic operating system [1]. F-Secure ported the runtime itself to boot natively. But please correct me.
> There is no thread support
The environment you run in is specifically curated for Go applications, such as the memory layout. I'd call this an "appliance" rather than enabling Go to be used for full-fledged generic operating system implementations.

Mixing sync and async views in the same application
As for embedded... I've only dabbled. Yeah you're not going to run Elixir on an Arduino or other very minimal bare metal embedded processor. But the Nerves Project (https://nerves-project.org/) which runs Elixir directly on SBCs is very well regarded. But either way it doesn't matter, since I thought we were talking about web dev, which is where Phoenix and Elixir just make more sense, for me.
-
what is the common usage of elixir
For me particularly I like it for things like APIs, Web Platforms (lower resource usage than other languages), and embedded devices via Nerves. However I've also used it on my endpoints to monitor them via Erlang's built in os_mon. Another usage is the distributed nature of erlang can allow you to do things like connect two nodes and run code on a remote node via remote procedure calls. This would allow you to execute something in a nearby geolocated node and reduce latency. Fly.io did a talk on this feature.

checkedc - Checked C is an extension to C that lets programmers write C code that is guaranteed by the compiler to be type-safe. The goal is to let people easily make their existing C code type-safe and eliminate entire classes of errors. Checked C does not address use-after-free errors. This repo has a wiki for Checked C, sample code, the specification, and test code.
