There are no really good GUI toolkits for Linux, are there?
⤋ Read More
@movq@www.uninformativ.de Yeah, give it a shot. At worst you know that you have to continue your quest. :-)
Fun fact, during a semester break I was actually a little bored, so I just started reading the Qt documentation. I didn’t plan on using Qt for anything, though. I only looked at the docs because they were on my bucket list for some reason. Qt was probably recommended to me and coming from KDE myself, that was motivation enough to look at the docs just for fun.
The more I read, the more hooked I got. The documentation was extremely well written, something I’ve never seen before. The structure was very well thought out and I got the impression that I understood what the people thought when they actually designed Qt.
A few days in I decided to actually give it a real try. Having never done anything in C++ before, I quickly realized that this endeavor won’t succeed. I simply couldn’t get it going. But I found the Qt bindings for Python, so that was a new boost. And quickly after, I discovered that there were even KDE bindings for Python in my package manager, so I immediately switched to them as that integrated into my KDE desktop even nicer.
I used the Python KDE bindings for one larger project, a planning software for a summer camp that we used several years. It’s main feature was to see who is available to do an activity. In the past, that was done on a large sheet of paper, but people got assigned two activities at the same time or weren’t assigned at all. So, by showing people in yellow (free), green (one activity assigned) and red (overbooked), this sped up and improved the planning process.
Another core feature was to generate personalized time tables (just like back in school) and a dedicated view for the morning meeting on site.
It was extended over the years with all sorts of stuff. E.g. I then implemented a warning if all the custodians of an activitiy with kids were underage to satisfy new the guidelines that there should be somebody of age.
Just before the pandemic I started to even add support for personalized live views on phones or tablets during the planning process (with web sockets, though). This way, people could see their own schedule or independently check at which day an activity takes place etc. For these side quests, they don’t have to check the large matrix on the projector. But the project died there.
Here’s a screenshot from one of the main views:
This Python+Qt rewrite replaced and improved the Java+Swing predecessor.

@lyse@lyse.isobeef.org Hmmmmmmmmmmmm … guess I should take a look at Qt. 🤔 That’s the one popular toolkit that I’ve never really tried for some reason. I really don’t like C++ (might as well use Rust), so I’ll also use Python.

@movq@www.uninformativ.de Don’t you worry, this was meant as a joke. :-D
There was a time when I thought that Swing was actually really good. But having done some Qt/KDE later, I realized how much better that was. That were the late KDE 3 and early KDE 4 days, though. Not sure how it is today. But back then it felt Trolltech and the KDE folks put a hell lot more thought into their stuff. I was pleasantly surprised how natural it appeared and all the bits played together. Sure, there were the odd ends, but the overall design was a lot better in my opinion.
To be fair, I never used it from C++, always the Python bindings, which were considerably more comfortable (just alone the possibility to specify most attributes right away as kwargs in the constructor instead of calling tons of setters). And QtJambi, the Java binding, was also relatively nice. I never did a real project though, just played around with the latter.

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).

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.)

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.

DeprecationWarning: 'mode' parameter is deprecated and will be removed in Pillow 13 (2026-10-15)
img1 = PIL.Image.fromarray(my_array, mode="RGB")
So I went to see the documentation:

And came out empty handed, that is, couldn’t understand what to do instead :(
And the plot thickens:

(@py5coding I guess you’ll want to check this out at some point. py5_tools.animated_gif uses this)

#GitHub #GitHubPages #fail This is driving me mad…
Images randomly deciding not to load on all my pages.
Is it just me? Is it my browser’s fault? Is it just in Brazil?
I was working on this #shapely + #trimesh page… and I can only see the last image (the animated gif)!

Update: On this exact page I have bungled the image URLs (I blame Marktext for being stupid and not using a relative reference). But I swear loading problems have been going on other well formed pages.
This is your friendly reminder that you could be making #PaperObjects with #Python and #py5, you know?

I wish I could watch this (maybe they’ll record it… but I’m not sure):

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:
https://github.com/villares/sketch-a-day/blob/main/admin_scripts/pngs_to_gif.py
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.

PEP 800: Disjoint bases in the type system
To analyze Python programs precisely, type checkers need to know when two classes can and cannot have a common child class. However, the information necessary to determine this is not currently part of the type system. This PEP adds a new decorator, @typing.disjoint_base, that indicates that a class is a “disjoint base”. Two classes that have distinct, unrelated disjoint bases cannot have a common child class. ⌘ Read more
