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.

Compiler Development: Rust or OCaml?
As someone who wrote a fair amount of Rust and OCaml code, I have to agree with the author.
While working at Routine (YC W21), I was tasked with porting our core library to iOS to minimize code duplication. This was a lucky opportunity to write something resembling a compiler: it took in schemas described with our in-house data exchange library and generated C (for FFI) and Swift code (for the end-users, i.e., iOS developers).
Since Routine uses OCaml for everything (which was a big motivator for joining the company—I wanted to see how that would work out), I wrote it in OCaml. The end result is a 3-5k LOC project. It's by no means a full compiler, but it was lots of fun to write. The language got in the way incredibly rarely. On average, it made my life a lot easier.
We did encounter our fair share of issues, mostly due to the cross-compilation tooling (we initially used esy [1], flirted with Nix, and eventually switched to opam-cross-ios [2]), third-party libraries, and intricacies of FFI. Those do take their toll on sanity.

OCaml 5.0 release (including multicore and effects)
What's the current status of Esy? https://github.com/esy/esy
Any plans to backport its design back to Opam?

2021 at OCamlPro
It's great to hear that Opam is making progress! I just wished that it would be more deeply integrated with Dune. A package manager that doesn't build is not very useful to be honest. Currently the only way to not have to care about switches and be able to clearly specify dependencies is to use the esy package manager[1] (which had lock files a while ago).

PR to Merge Multicore OCaml
If you start a project today I would really try to use esy (https://esy.sh/)
I actually don’t use it myself but it seems to bring the modern programming language experience to OCaml

Frustrated by lacking cross platform support (hoping to be wrong)
Alternatively, you can use esy.sh for a simpler setup/build process (it does not require running in a Cygwin shell).

Opam, PNPM, Node, Esy, Docker, ReactNative on 128GB Mac
Running esy does not work. Apparently, my environment does not know that it is there. Anyone know what is going on here? I have posted this in the discussion for esy@next here. I will get back to you all when I figure this out.

Rust: Box Is a Unique Type
If you have an object that's !Unpin, then Miri will not apply uniqueness rules to anything containing it [0], including boxes and &mut references. (In the example code, replacing the PhantomPinned with a () will make Miri complain again.) This is considered a temporary (if long-lived) measure to allow async executors to manipulate pinned futures without invalidating all their references and whatnot. Thus, it might be seen as undetected UB, in lieu of a permanent solution.

Fivefold Slower Compared to Go? Optimizing Rust's Protobuf Decoding Performance
That would be true if you used `Vec::clear` too, it doesn't allocate a new vector. My point was that you still end up running Drop implementations with RepeatedField, just not all at once. See https://play.rust-lang.org/?version=stable&mode=debug&editio...

Borrow Checking Without Lifetimes
Self-referential structs work fine in Rust and always have.
https://play.rust-lang.org/?version=stable&mode=debug&editio...
The compiler will correctly prevent you from moving the value.
The other way to have a struct that starts out as non-self-referential and then becomes self-referential can be achieved with `unsafe` and `Pin::new_unchecked`, which is how `async {}` is handled.

Substitute the sleep with a combination of doing computation/work and the OS thread scheduler, and you can see how the bug surfaces.
