You can always convert from Polars to Pandas. Plotnine will do it automatically for you, even.

Accessibility. It's both a very common abbreviation and very easy to search for.

You have absolutely no clue what you're talking about, mate. .NET is like Java. It's behind critical systems you haven't heard of because they're not flashy or glamorous, so you have no idea how prevalent they actually are.

The other posters are right. Most .NET projects today are backends, where it's used similarly to how Java is used.

The AI should've told him that you can have a local gitignore (.git/info/exclude)

Maybe they say it as an "ew" diphthong instead? As an ESL, that makes sense to me.

Javascript didn't have the same FFI story with C/Fortran as Python. That's what allowed libraries such as numpy, scipy, pandas, etc. to flourish.

For what it's worth, pyright highlights the problem in your first example:

    t.py:11:20 - error: Argument of type "Self@C" cannot be assigned to parameter "self" of type "B" in function "__init__"
        "C*" is not assignable to "B" (reportArgumentType)
    1 error, 0 warnings, 0 information 

ty and pyrefly give similar results. Unfortunately, mypy doesn't see a problem by default; you need to enable strict mode.

In Python, they're very easy to use. Define your schema with Pydantic and pass the class to your client calls. There are some details to know (eg field order can affect performance), but it's very easy overall. Other languages probably have something similar.

And do what? Use a Chromium-based browser, which is infinitely worse?

Forks exist

If Mozilla needs ill-fated diversification attempts to try to stay afloat, forks are in an even worse situation.
