Um dia em que você conta pra alguém sobre a #LiveDePython do @dunossauro@dunossauro nunca é um dia perdido!
Random musing from a #Python creative coder:
I have this naïve cumbersome thing for dealing with collinear vertices in a polygon (like a vertex in the middle of an edge that doesn’t change the shape of the polygon, and I tried to replace it with some clever #shapely method such as .simplify(…) or .buffer(0) and failed miserably. So I’ll have to keep my home made check-area-every-three-vertices thing for now…
I’m kind of proud of my idea of representing polygons as a set of frozensets of edge vertex pairs because it eliminates all visually equivalent rotations and reverse ordered rotations (that is, if you don’t have pesky collinear vertices).

I was always under the wrong impression that Tkinter is bundled with Python.
It should be. Maybe your distro splits it off. 🤔

@movq@www.uninformativ.de I never programmed with Tkinter myself and it’s been ages that I ran a program which used it. I always thought that it looks awful. But maybe there are nicer themes these days. I just wanted to give the demo python3 -m tkinter a try, but this module doesn’t exist. I was always under the wrong impression that Tkinter is bundled with Python.

@lyse@lyse.isobeef.org Xfce is nice, but it’s also mostly GTK. I don’t really know the answer yet. For now, I’ll just avoid anything that uses GTK4.
For my own programs, I might have a closer look at Tkinter. I was complaining recently that I couldn’t find a good file manager, so it might be an interesting excercise to write one in Python+Tkinter. 🤔 (Or maybe that’s too much work, I don’t know yet.)

Eu soube fazer um overlay de instersecção, filtrar as com área menor que 100m2 e usar o .explore() pra colorir as massas por área, já fiquei feliz, mas queria mais rsrsrs.

Listening to the JetBrains survey thing I always worry about the sampling bias… All the cool scientists using Python, all the journalists doing data journalism, the urban planners and geospace people, the blender people, the people doing movie post-production pipelines, all the hobbyists… I think the survey doesn’t reach or represent a large chunk of Python users.

«Para entender uma atribuição em Python, leia primeiro o lado direito: é ali que o objeto é criado ou recuperado. Depois disso, a variável do lado esquerdo é vinculada ao objeto, como uma etiqueta colada a ele. Esqueça as caixas.»

Updating my #Processing + #Python tools table:
After some years, things changed and my opinions changed a bit too:
#py5 is going supper strong and the “new snake_case names” are not an issue for me anymore. I used to worry a lot about all the Processing Python mode examples and teaching materials out there, and some of my own, with “CamelCase Processing names” I’m not worried at all about it anymore!
For the record, Processing Python mode is just a legacy thing, no one should start anything with it.
The great pure Python Processing implementation project #p5py seems stalled, latest release in Dec. 2023 :((( Advancing it was always going to be an uphill battle…
The unrelated Brython based site
p5py.comseems to be gone, so I removed it from the table.I added a link to my own #pyp5js hack py5pjs/py5mode because this is what I’m using most nowadays.

** Make awk rawk **
A friend online recently replied to something I wrote about awk by saying:
[…] it’s a danged shame [awk] didn’t continue to evolve the way Ruby, Python, PHP have evolved over the decades.
I had exactly this thought while working on my slightly unhinged“lets see if I can implement a basic scheme using awk by writing an assembler and VM in awk,” skwak. Which eventually lead me to start noodling on how to layer in some modern niceties into awk, without breaking awk’s portability.

I have a Python script that transforms the original YouTube channel Atom feed into a more useful Atom feed by removing the spam description and replacing it with the video duration, filtering out videos by title, duration, etc. I just updated it to exclude the damn Shorts garbage more efficiently. Finally, YouTube updated their Atom feed generation, so that the video URL contains /short/ if it’s of this useless kind. Never thought that they ever actually will improve their Atom feeds. Thank you, much appreciated!
The command line version is here:

I should add a “public domain dedication” to both scripts…
I have this very simple #Python script that uses #imageio to convert all PNG files on a folder into a #GIFAnimation, and this is a #FreeSimpleGUI version of it (I usually run a command line version).
As I usually run #gifsicle on the command line after creating a GIF, I decided to update it to add #pygifsicle to do it for me and save a step.

@movq@www.uninformativ.de I’d love to have a Python script pushing my local CSV, too. But that’s never gonna fly, not in a thousand years. I can’t imagine that ever becoming reasonably stable without having to fix everything after the reverse-engineered API changes again.

@lyse@lyse.isobeef.org I do my timetracking in a little Python script, locally. Every now and then, I push the data to our actual service. Problem solved – but it’s a completely unpopular approach, they all want to use the web site. I don’t get it. Then, of course, when it’s down, shit hits the fan. (Luckily, our timetracking software is neither developed nor run by us anymore. It’s a silly cloud service, but the upside is that I’m not responsible anymore. 🤷)
Some of our oldschool devs tried to roll out local timetracking once, about 15 years ago. I don’t remember anymore why they failed …
This is developed inhouse, I’m just so glad that we’re not a software engineering company. Oh wait. How embarrassing.
Oh to be anonymous on the internet. That must be nice. 😅
Cheers @danzin@danzin, was it you who added a PR to core #Python about pprint?

One of the nicest things about Go is the language itself, comparing Go to other popular languages in terms of the complexity to learn to be proficient in:

@bender@twtxt.net Here’s a short-list:
- Simple, minimal syntax—master the core in hours, not months.
- CSP-style concurrency (goroutines & channels)—safe, scalable parallelism.
- Blazing-fast compiler & single-binary deploys—zero runtime dependencies.
- Rich stdlib & built-in tooling (gofmt, go test, modules).
- No heavy frameworks or hidden magic—unlike Java/C++/Python overhead.
