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.

OCaml: a Rust developer's first impressions
Some of your questions might be answered in this book (free online version): https://dev.realworldocaml.org/
- Compiler Development: Rust or OCaml?

Nix-Powered Development with OCaml
I don't think they're wrong
the Jane Street side are quite prolific with blog posts etc
as a newcomer to OCaml one of the first, and nicer-looking, intro resources you'll likely encounter is the Real World OCaml book https://dev.realworldocaml.org/ which unfortunately does everything using Base instead of the stdlib
Personally that didn't sit right to me and I prefer to use the stdlib by default (which seems fine and not in need of a wholesale replacement)
-
Comparing Objective Caml and Standard ML
This is an oldie but a goodie.
OCaml has, unlike Standard ML, grown quite a lot since this page was made.
In particular, the section "Standard libraries", I'd recommend looking at:
https://dev.realworldocaml.org/
A couple of places where the comparison is outdated:
- OCaml using Base [1] allows for result-type oriented programming
- OCaml using Base uses less language magic and more module system
While there was and is truth to the distinction that SML is for scientists and OCaml is for engineers, this dichotomy is getting dated: OCaml is under active development, which means that scientists who want better tooling will choose OCaml. For example, 1ML [2] by Andreas Rossberg was built in OCaml.

Resource recommendations for a beginner.
Real World OCaml (version 2 is finally out) is also pretty good.
-
OCAML HELP!
Real World OCaml is also a good resource, geared more towards people who already have some programming experience and want a more industry/practical focused learning experience.

Teach Yourself Programming in Ten Years
ocaml.org’s new website is packed with lots of great early intros.
most learners eventually gravitate towards Real World OCaml https://dev.realworldocaml.org/ for additional learning.
Unfortunately, the learning resources for different domains out there isn’t as highly curated or prolific as, say, rust. If you do web dev like me, it takes a bit more work to find the tools and put them together. But the language itself lends itself well to systems level programming.
Fortunately, the forum is a great help.

Help getting started with Ocaml
In general, better read the second edition which is updated to use current Core versions. A print version was published recently.
-
learning ocaml this semester.
I recommend https://dev.realworldocaml.org/ and https://cs3110.github.io/textbook/cover.html

Functional Reactive Programming
Elm is not dead. It just prefers a slow release schedule but is still actively worked on in the background.
That said, you might want to check out OCaml for general purpose programming. Super fast compiler, great performance, can target both native and JS.
It is easier to use than Haskell due to defaulting to eager evaluation (like most languages) strategy instead of laziness and being generally more pragmatic, offering more escape hatches into the imperative world if need be. Plus great upward trajectory with lot's of cool stuff like an effects system and multi-core support coming.
Real World Ocaml is a decent resource: https://dev.realworldocaml.org/

More than you've ever wanted to know about errors in Rust
I couldn't find it in the API guidelines either. From what I understand, the idea is that any trait bounds, which includes generic type parameter bounds and lifetime bound on a type (struct or enum) would be repeated back in the impl block
there is a nice discussion on this issue here: https://github.com/rust-lang/rust-clippy/issues/1689

New clippy lint: detecting `&mut` which could be `&` in function arguments
You should not blindly follow clippy lints. They are sometimes wrong. Another example https://github.com/rust-lang/rust-clippy/issues/9782 .
- Let else will finally be formatted by rustfmt soon
-
My deduplication solution written in Rust beats everything else: casync, borg...
I often write () = f() to assert that f() is unit. Unfortunately clippy warns on such code ( https://github.com/rust-lang/rust-clippy/issues/9048 ). There are very recent pull requests for this bug, so hopefully this bug will be fixed very soon. But meanwhile I invented this workaround: [()] = [f()] :)

Any open source projects willing to take in juniors?
Apart from running clippy on many projects being essential, clippy is also an exceptionally welcoming project, no matter your prior knowledge.
-
Any new Opensource projects in (rust) looking for contributors. I want to start my journey as an OSS contributor.
clippy is a great place to get started :) though it isn't exactly new.
-
I want to contribute in a big project
clippy is also pretty compiler-adjacent and unlike rust-analyzer uses rustc's internal APIs. Don't let the size of the code base scare you off! It's actually feasible for a newcomer to contribute even such a substantial change as a new lint, and we have issues labeled as "good first issue" that come with mentorship, so you don't need to go it alone.
-
rustc-plugin: A framework for writing plugins that integrate with the Rust compiler
Yes, you could use it to write a lint. Although you might find it easier to just fork Clippy and add your own lints to their existing framework.

Rust Tips and Tricks #PartOne
They are two of my favorite Rust tools. If you haven’t tried them yet, I highly recommend giving them a try. Clippy can detect various lints in your code and guide you towards writing more idiomatic code. To install Clippy, simply run rustup component add clippy, and to run it within your workspace, execute cargo clippy. For more details, visit Clippy’s GitHub repository.
