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.

Shells Are Two Things
This is well made case - but I'm not sure I buy the central argument. Within some basic limits, I don't think terseness and readability have the contradiction made out here, because in programming we have abstraction, which gives us both.
To take the example command that's given:
beef.txt | grep "lasagna" | sort -n | uniq
Sure, writing the logic out for this in something like python straight out the bat with only the standard library might look messy, but with one basic convenience function it could quickly be:
search(for='lasagna', in='beef.txt', clear_duplicates=False).sorted()
Obviously you have to write the function in the first place, but I'd say if you're doing something like this often, it's easily worth spending that 2 minutes. And if you're not doing this often, you'll have a faster time writing more code, but keeping less heavy lifting of "how does bash pipe together" in your head.
I shared a project here a few weeks ago experimenting with what my dream shell might look like, what surprised me more than anything else, was how easy writing a repl environment actually is. I put a scrappy one together as one person in a few hours, so I don't understand why as developers we've reached general language models before being able to make a powerful, but new-user friendly shell.
Also, completely unrelated note, but posix only allows passing back strings - but isn't this true of web apis too which we use all the time? How come no json as a standard passback from programs?

click-web: Serve click scripts over the web (Python)
Context: "click" - "Command Line Interface Creation Kit" - easily create CLIs from Python code, via adding decorators: https://github.com/pallets/click
"click-web" in turn turns the click CLI app into a web app with one line of code.
- Anyone want to start a project with me.

How does "python3 *file* -*letter* work?
there is also click, it is more straight forward and also nice to keep the relevant code where the code is. https://github.com/pallets/click/

Overhead of Python Asyncio Tasks
I don't have huge experience with Python, but I used async code with C#/Typescript and lately I had to use some asyncio magic.
I found this article: https://blog.dalibo.com/2022/09/12/monitoring-python-subproc... and while async/await syntax is the same, it's not entirely clear for me, why there's some event loop and what exactly happens, when I pass function to asyncio.run(), like here: https://github.com/pallets/click/issues/85#issuecomment-5034...
So, you can use it and it's not that hard, but there are some parts that are vague for me, no matter which language implements async support.

I am sick of writing argparse boilerplate code, so I made "duckargs" to do it for me
Hmm… did you try such approaches, as [click](https://github.com/pallets/click) or[tap](https://github.com/swansonk14/typed-argument-parser)?

Shells Are Two Things
I've used click [1] a lot to build Python tooling scripts the past few years. Click usage is "sort of" similar to the author's proposed solution. There's also a small section here [2] that describes some of the issues covered in the article (in context of argparse).

Tomu – A family of devices which fit inside your USB port
I think the success of Arduino in the hardware world can be explained in a similar way, as the relative success of "command line app frameworks" like Click[1], or even much lighter-weight libraries like argparse[2]. You absolutely can get away with using just getopt[3] (and people experienced with it will likely strongly prefer it). However certain factors such as a more declarative API, a nice logo, the existence of an ecosystem (even if you're not actively drawing from it), an official "branded" forum, etc can all play into picking a more complex solution, with more baggage you don't need, certain oddities that may throw users off, etc.

Advice for a final project in python without web?
Exactly! You can also use a library like click (https://github.com/pallets/click) to help take care of the command line side, while you focus on the 'business logic' of your application :)
