🎉 Excellent thread on asyncio.TaskGroups, ExceptionGroups, and why these are much better than the tools we have today for managing tasks:

Exciting news: @gvanrossum has just merged TaskGroups to #asyncio. They will be part of Python 3.11 and I can't hold my excitement!

I was curious what this looked like for

@pypi

so I ran some queries: For the top 1% (~3.5K) packages: - mean: 2.17 maintainers - mode: 1 maintainer - median: 2 maintainers - max: 30 maintainers I think the mode of 1 maintainer is probably as concerning as npm's average of 32.4!

In case you missed the bombshell from this article: "The Top 1% packages (14,941) had an average of 32.4 maintainers per package"

I get uneasy when I see a Python package with 5 or more, can't imagine seeing 32 or more accounts with write access to a package.

A Tale of Two NaNs (A #Python 🧵) (Plus a bonus experiment in Twitter fonts that may end disastrously)

One reader noticed that the diagrams used whichever monospace font was configured for the system. I wrote a little tool that replaced the font on the exported SVGs with `font-family: monospace`. Left is iOS using "Menlo" and right is Ubuntu+Firefox using "DejaVu Sans Mono" 😍

Comparison of two fonts depending on the platform. Left is Menlo on iOS which has slashes in the zeroes. The right is DejaVu Sans Mono on Ubuntu and Firefox which has dots in the zeroes.

That is so awfully dismissive and tone deaf. No, people don’t want Safari to "just go away". People (of all genders!) want Apple to respect user choice and stop forcing everyone to use Safari on iOS whether they want to or not. It’s pretty simple, really.

Gosh. Catching up with tech Twitter this morning and there seems to be an angry pocket of men who really want Safari to just go away. Do we really want to live in a 95% Chromium browser world? That would be a horrible future for the web. We need more voices, not fewer.
