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.

Are there any languages that allow units?
Julia's Unitful package is one of my favorites. https://github.com/PainterQubits/Unitful.jl
Tangentially related, LaTeX's siunitx package makes typesetting units a joy. https://ctan.org/pkg/siunitx

Similitude.jl is new more powerful Quantity than Unitful.jl
Not sure why you think more units is more powerful. Defining specific units is seldom the difficult part of dealing with units in code. I'd say that just looking at the tests for Unitful (excluding the separate tests for dates) to the tests of Similitude that there seems to be a lot more functionality in Unitful. What are the advantages of these alternate packages? And I do not think focusing on "more powerful" is too useful unless qualified appropriately.

ModelingToolkit, Modelica, and Modia: The Composable Modeling Future in Julia
It's really two separate problems but they kinda interact.
Unitful quantities with heterogeneous units don't have a `zero` function that works correctly, which gets in the way inside numerical routines. [0] There are other places where 0 or 1 is added, which is an error for quantities but not for plain real numbers. [1]
Zygote doesn't handle mutating arrays. [2]

Atlas, a (hopefully) better engineering IDE
Julia has the Unitful package [1], which does a decent job. It's quite ergonomic, and Julia's design helps with making existing code/libraries play nicely with Unitful-encoded units/values.

GNU Units
I've seen a few before, and a quick search yielded a bunch for me, right off the bat. By no means exhaustive:
Julia: https://github.com/PainterQubits/Unitful.jl
Python: https://pint.readthedocs.io/en/0.6/
C++: https://github.com/nholthaus/units
etc.
And yes, it has always struck me as strange that date/time/calendar libraries are standard as canonical libraries shipped with language distributions, but units are not.

Kernighan and Pike were right: Do one thing, and do it well
FWIW, ls in Research-V6 back in 1975 had 10 options. https://github.com/dspinellis/unix-history-repo/blob/Researc...
By BSD 3 in 1980 it had 11 options. https://github.com/dspinellis/unix-history-repo/blob/BSD-3-S...
The thing is, we can see even from the 1970s 'ls' how the Unix model doesn't meet the goal "to chain these simple programs together to create complex behaviors".
There is no option to escape or NUL terminate a filename, making it possible to construct a filename containing a newline which makes the output look like two file entries.
The option for that was added later.
There's also the issue that embedded terminal codes will be interpreted by the terminal.

Linux is not as smooth as windows
Here's a 1997 citation for "top cpu processes." It's not as close to the original 1984 release as I would like, but it's better than Wikipedia. https://github.com/dspinellis/unix-history-repo/commit/aee34003d7964653c44c31f5bf6bcf136b32c4f3

GPT based tool that writes the commit message for you
> The “why” goes into the PR and more importantly, engineering documentation and inline comments
This just ensures that the “why” is lost when someone comes looking years later.
From experience, SCM metadata is far more durable than just about any other work product we produce. Five decades later and RCS commit info was still available for the Unix sources, and history could be reconstructed: https://github.com/dspinellis/unix-history-repo
I’ve used 35-year-old commit messages to help understand a long-standing issue, decades after all other related organization tooling and data had disappeared.

What should be included in a history of the Rust language?
P.S. I remember I looked into early versions of C (they survived in Unix historic releases) and that, finally, revealed to me why C does something really stupid and conflates arrays and slices (pointers). Initially C had no arrays! Or, rather, what it called arrays were, actually, pointers. “Normal” arrays were added at some point, but because these weird slices/pointers were already there that caused endless confusion. It wasn't resolved before C became popular and after that it was too late. Go repeated that mistake with slices, of course.
