By the way, if you are starting up your own fediverse server, it may be tempting to blindly copy someone else’s block list, but some corners of the fediverse have been a bit over eager with full instance bans, in my opinion, which tends to break the whole federation model (imagine if you couldn’t email anyone with a certain university’s email domain because your email provider disagrees with the university policies).

If an instance is putting a lot of irritating stuff in your server’s global timeline, it might be better to just mute them from the global timeline.

Here's a typing puzzle: https://mypy-play.net/?mypy=latest&python=3.11&flags=strict&gist=6baf24cc7bc82ac6e8f9995d361f682e

I want to have a method decorator that constrains the type of `self` with respect to a generic, but (obviously) does not _reduce_ the type of `self` to require that it accept any instance of the bound the decorator requires. Do I just need higher-kinded TypeVars for this (https://github.com/python/typing/issues/548) or am I missing something obvious?

It still feels like magic to me that #NumPy allows slices that aren't "rectangular". They can be arbitrary index lists, which in the simplest form allows you to "draw" polygons by first selecting the pixels and then making a single assignment. That's what ski.draw.polygon does.

But it goes further, you can have really arbitrary lists of multi-dimensional indexes so they don't have to be continuous or anything. My simple high-school math mind can barely accept it 🤯

#Python

NumPy 2.0 is coming. You should be excited and terrified in equal measure.

Wow. Meta commits to dedicate three engineer-years to implement the removal of the GIL from #Python and fix upcoming compatibility and performance issues with it.

All this dependent on whether the Steering Council accepts PEP 703.

Need to work with timezones in #Python?

Don't use pytz! Use zoneinfo.

It's included in the Python standard library from Python 3.9 onward and pip install-able if you're on Python 3.8.

If your code needs to run on Windows, note that you'll need to pip install tzdata to use Python's zoneinfo module properly.

The scope of a feature request often isn't obvious to the asker. For example, someone just asked on the Python forum to make it possible to subclass `pathlib.Path.` Meanwhile, Barney Gale has spent the last *three years* or so working on all the nuances of that, and it's finally making it into Python 3.12 although there's more to do. He worked so much they made him a core dev. #Python #TodayInOpenSource

Once again, I am so frustrated by Python static typing https://github.com/pallets/click/issues/2558 If any typing expert out there wants to help, that would be wonderful. #Python

I'm on the job market. Any early stage startups hiring lead engineer positions, DM me please! 🙂

This weekend I’ve spent more time in the tox rabbit hole than I expected, but check out how I’ve cut the runtime of full tox runs of the attrs test suite by 75%:
