BREAKING: #CPython 3.13.10 and 3.14.1 changed the multiprocessing message format in patch release. As a result, programs using multiprocessing may break randomly if they are running while #Python is upgraded (i.e. need restarting).
But apparently it's not a big deal, since all the cool kids are running Python in containers, and nobody is using Python for system tools anymore. Everything has been RIIR-ed and Python is only omnipresent in some backwaters like #Gentoo.

Any #Python newbies out there? (Or experts that need to teach Python)
Would you have a specific online tutorial to recommend for someone who wants to learn Python without any prior programming experience? One that also explains how to install it ?
I was thinking of something like this:

Yeah, why not neglect all the good recommendations in the #Python ecosystem, and instead fork your own C extension package, force people to build it with #ZigLang (it's still C), add unconditional dependency on that, and on top of that, refuse to publish wheels, "allowing for optimised compilation according to your machine's specific architecture and capabilities, instead of some (low performance) common denominator."
Fortunately, looks like #Gentoo can just ignore all the fancy crap and compile it with GCC.

My very first experience with Python was generating programmatic art using the Turtle module.
Don’t let anyone tell you coding is only for pros, it can be an incredibly fun and liberating experience.

In #Python, you could write sensible and transparent code, like this:
if (curNode):
curNode = curNode.next
But if you prefer something that is functionally identical, but harder to read, try this:
curNode and (curNode := curNode.next)

I rewrote a data analysis pipeline, moving it from #python to #julialang . I am now in love with the threading support in Julia.
The task is very parallelizable but each thread needs random read access to a tens-of-GB dataset. In Python (with multiprocessing, shared stores, etc) data bookkeeping was a nightmar…

Let's get this straight: it is entirely normal for a #OpenSource project to accumulate bug reports over time. They're not a thing to be ashamed of.
On the contrary, if you see a nontrivial project with a very small number of bug reports, it usually means one of the following:
a. you've hit a malicious fake,
b. the project is very young and it doesn't have many users (so it's likely buggy),
c. the project is actively shoving issues under the carpet.
None of that is a good sign. You don't want to use that (except for b., if you're ready to be the beta tester).

How to absolutely *not* do #OpenSource: require people to commit to work on other issues with your project in order to file bugs. So, sorry, #Typer, I won't be filing bugs. You figure out how you messed up your release yourself.
Also, please don't use #FastAPI. They are clearly bothered by the fact that people dare use their projects and waste their precious time with support requests.

With build 1.4.0, it is now possible to easily dump effective package metadata!
So getting the version of a package in the current directory is now as easy as `pipx run build --metadata 2>/dev/null | jq -r .version`.
This is NOT like parsing pyproject.toml or whatever. It builds the package and looks at the result. So it works even with…

When you notice twine uploading a 400M sdist for a tiny #Python package, you know something went wrong.

Ah yes, brew upgraded some ssl-related .so file and broke the python binaries linked against it. Again. So many venvs now lay in ruins.
There has got to be a better way.
(Why do pyenv-built pythons seem to habitually get built using the brew-provided libraries? There's no way for brew to know about that dependency.)

#Sphinx joined the list of packages dropping #Python 3.11 (and therefore #PyPy) support. Of course, we could just go through the effort of dropping it from respective packages in #Gentoo, given it's not technically that common… but honestly, at this point I have zero motivation to put the extra effort for this, just to learn that next month some core package starts requiring Python 3.12.
So, would anyone really mind if I removed Python 3.11 and PyPy support completely from Gentoo packages?

Binary partitioning with k-d trees is silly amazing. And with OSM data in radians and pretending the planet is a perfect sphere, scikit-learn's BallTree works wonderfully for quickly finding things nearby some reference point.

I've almost missed my train today while filling bugs over another #slop release of #autobahn. This was the last straw. Well, the penultimate one, though I don't know why I'm even bothering.
#Python #NoAI

Totally normal #Python upstream attitude:
1. Ignore a reply on a bug report for 3 years.
2. Install a #StaleBot in the middle of the night.
3. 7 minutes after the bug is marked stale, claim that you "never heard back on this" and that "the issue was somewhere downstream", without even checking another linked issue.

Uh, I'm seriously starting to wonder if I should start filing bugs to people "please move away from autobahn / txaio, it's turned into complete #AI #slop, with every release introducing major issues, and depending on it is plain dangerous."
