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.

format vs. formatter - using and implementing
See also format.lisp for what I have so far. This will also run with sbcl and/ or abcl. If you've made it this far I'd also appreciate feedback on whether my chosen subset (see the comment at the top of the file) of Common-Lisp's format is somewhat useful and/ or which features you would miss the most.

Murmel 1.4.1
JMurmel also has commandline flags to turn off language features for experimentation purposes, see e.g. implementing cons, car and cdr in Lambda Calculus.

Java OSS with the WORST code quality you’ve ever seen?
To my defense, I have started my Lisp compiler/ interpreter mostly for recreational purposes to do the exact opposite of what the checkstyle nazis at my $job demand.

Would welcome feedback on Murmel 1.0
Re: automated tests; there are JUnit tests in https://github.com/mayerrobert/jmurmel/tree/master/lambda/src/test/java, and the files in https://github.com/mayerrobert/jmurmel/tree/master/lambda/src/test/lisp are run automatically, too, and their output and result is checked. Maybe I should add a file HACKING.md or something that gives an intro of the project structure and build system?

Introduction to GPU Programming in Chapel
Thanks, @subharmonicon!
While Chapel can run on many different systems, the main goal is making HPC programming much easier. Therefore, we are currently focusing on hardware that you can find in HPC systems (NVIDIA, AMD and Intel). Metal doesn't fall into that category, unfortunately. So far, the name came up infrequently in our discussions IIRC (especially targetting SPIRV), but we haven't heard from any [potential] user who may be interested in it. I would encourage you or anybody else interested in it to create an issue asking for the feature: https://github.com/chapel-lang/chapel/issues/new. Seeing public interest in that direction can change our prioritization.
One thing that I wanted to add that's not in the blogpost is the "cpu-as-device" mode. With that mode, you can use any machine, even one without a GPU, to write applications using Chapel's GPU features. That mode is for those who want to do initial development/debugging on their personal laptops before putting their application on an HPC system. In other words, while you can't use Metal directly, you can still write GPU-enabled applications in your Mac using Chapel, if the end goal is to run it on an HPC system. More details on cpu-as-device: https://chapel-lang.org/docs/main/technotes/gpu.html#cpu-as-...

Mojo is now available on Mac
Agreed. Here is a serious contender[0] minus all the hype and the $100M in VC money. You would expect a minimum of interest given how Mojo is received by the community, but not really in practice.

Rust vs. Julia in Scientific Computing
Cray is pushing their own language as well, Chapel.
https://chapel-lang.org/
As for Julia on Cray,
"Julia — The Newest Petaflop Family Language We Have Started to Love"
https://www.avenga.com/magazine/julia-programming-language
> Julia is one of the few languages that are in the so-called PetaFlop family; the other languages are C, C++ and Fortrant. It achieved 1.54 petaflops with 1.3 million threads on the Cray XC40 supercomputer.

Ask HN: How do I get the most benefit out of my programming language?
I suggest posting to a PLT focused resource, such as http://lambda-the-ultimate.org/
That said, a bit confused about the languages you reference in this context (Python, C#, JS) - didn't see any mention here or at your github repo of languages (some relatively ancient) in this space designed.

Twelve Days of Chapel: Advent of Code 2022
We needed the implicit conversion to `uint` in order for the overload resolution rules to make reasonable choices when faced with binary overloads for all of the numeric types. The document I linked talks through the examples. The case we were facing is something that we shared with `C#` -- in `C#` terms, if I make overloads for `f` for all numeric types (see https://github.com/chapel-lang/chapel/blob/main/test/types/coerce/allNumericsBinary.cs if you want to know exactly what I am talking about), then `f( myInt, myUlong )` runs `f(float, float)` which makes no sense. Especially if you care about numerical accuracy or program performance.
