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.

Eio 1.0 Release: Introducing a new Effects-Based I/O Library for OCaml

OCaml: a Rust developer's first impressions
For 5.0+ you might want to look at https://github.com/ocaml-multicore/eio for how effects can make async much more pleasant

How Much Memory Do You Need to Run 1 Million Concurrent Tasks?
Great post! I would love to see this extended to OCaml 5 (with eio) and Haskell

OCaml 5.0.0: multicore support and effect handlers for OCaml
Second, effects enable a new style of concurrency libraries like eio that forgoes the need to wrap every asynchronous computation in a monad.

What’s so great about functional programming anyway?
> This is realllly unidiomatic in real world Haskell.
Whether idiomatic or not does not matter. It proves my point:
IO won't save you, and even very mundane effects are not part of the game…
Idris is the "better Haskell" sure, but the effect tracking is still part of the uncanny valley (still IO monad based).
Koka is a toy, and Frank mostly "only a paper" (even there is some code out there).
The "Frank concept" is to some degree implemented in the Unison language, though:
https://www.unison-lang.org/learn/fundamentals/abilities/
Having a notion of co-effects (or however you please to call them) is imho actually much more important than talking about effects (as effects are in fact neither values nor types—something that all the IO kludges get wrong).
I think the first practicable approach in the mainstream about this topic will be what gets researched and developed for Scala. The main take away is that you need to look at things form the co-effects side first and foremost!
In case anybody is interested in what happens in Scala land in this regard:
https://www.slideshare.net/slideshow/embed_code/key/aLE9M37d...
https://docs.scala-lang.org/scala3/reference/experimental/cc...
But also the development in OCaml seems interesting:

Look mom, "effects", but without the monad headache!

Practical OCaml, Multicore Edition
To enable access to all these features, an exciting new library called Eio is being developed. It uses a new paradigm of direct-style concurrent I/O programming, without the need for monads or async/await, thus avoiding the function colour problem.

Gokrazy – Go Appliances
Interesting, and thanks.
I didn't know about those. I kind of thought you may have used MirageOS, which I had read about earlier. It is done in OCaml.

Unix system programming in OCaml (2014)

"MirageOS is a library operating system that constructs unikernels for secure, high-performance network applications across a variety of cloud computing and mobile platforms."

PostgreSQL reconsiders its process-based model
That was/is part of the promise of the whole unikernel thing, no?
https://mirage.io/ or similar could then let you boot your database. That said, it's not really taken off from what I can tell, so I'm guessing there's more to it than that.

Is there an operating systems that is a runtime of a programming language?
MirageOS is a runtime for OCaml to create unikernels. They describe themselves as "library operating system". Probably not quite what you were asking for, but I think it's quite interesting for certain use cases (e.g. running services as standalone unikernels in VMs or embedded devices instead of "traditional" programs on top of a general purpose OS).
