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.

Swift for TensorFlow Shuts Down
The dependence on library authors is always a challenge in any language. You might have one author using `[a]` where another uses `PositiveNumeric a, Fin n => NonEmptyList n a` for the same thing. You can always just annotate whatever the library author used (e.g. they return a list of strings, so you use List[str]).
There are some interesting further add ons that seem very python, allowing you to go further. For example, with a pandas dataframe you can just say your type is a dataframe which isn't so useful, but it's possible to hack your own types onto it in the vein of https://github.com/CedricFR/dataenforce, or use things like https://smarie.github.io/python-vtypes/ to get smarter typing on things the authors didn't type. I expect that trend will continue.
What fascinates me about python's types is actually the very fact that they are bolted on. You have a language that lets you do crazy things and a type system trying to catch up and make it convenient to verify those crazy things. It's a nice complement to the usual developments of verifying all of the things and slowly extending the set of things you can do.

[D] Question: Do you enforce a data format in Pandas? When collecting data over a long period of time, wouldn't it be useful to use a system with versioned schemas that specify how various data entries must be formatted? Give me feedback on this Open Source idea:
https://github.com/CedricFR/dataenforce enforces column names and types, no versioning though. My first instinct is that important data should be stored in databases which enforce schemas, and that should be separate from the python code that reads it.

Transpiler, a Meaningless Word
> Another problem is that there are hundreds of built-in library functions that need to be compiled from Python from C
An approach I've advocated as one of the main authors of py2many is that all of the python builtin functions be written in a subset of python[1] and then compiled into native code. This has the benefit of avoiding GIL, problems with C-API among other things.
Do checkout the examples here[2] which work out of the box for many of the 8-9 supported backends.

Why I'm still using Python
https://github.com/py2many/py2many/blob/main/doc/langspec.md
Reimplement a large enough, commonly used subset of python stdlib using this dialect and we may be in the business of writing cross platform apps (perhaps start with android and Ubuntu/Gnome)

Codon: A high-performance Python compiler
For py2many, there is an informal specification here:
https://github.com/py2many/py2many/blob/main/doc/langspec.md
Would be great if all the authors of "python-like" languages get together and come up with a couple of specs.
I say a couple, because there are ones that support the python runtime (such as cython) and the ones which don't (like py2many).

Omyyyy/pycom: A Python compiler, down to native code, using C++
Cython doesn't consume python3 type hints and needs special type hints of its own. But it's certainly more mature than other players in the field.
What we need is a rpython suitable for app programming and a stdlib written in that dialect.

Implicit Overflow Considered Harmful (and how to fix it)
Link to the test that's relevant for this discussion:
https://github.com/adsharma/py2many/blob/main/tests/cases/in...
This is an explicit deviation from python's bigint, which doesn't map very well to systemsey languages. The next logical step is to build on this to have dependent and refinement types.
