Trouble exporting P3D via PGraphics recording (OpenGL error 1282) :blobcatsad:
Dear @doctormo@doctormo, I’m a great admirer of your work in general and hopefully I won’t creep you out by telling everyone I’m your fan!
As a creator of digital vector-based art I find the color management stuff (trying to figure how to generate things to print “in CMYK”) mind boggling. I slowly try to read and acquire the concepts and vocabulary to understand more about this. I’m grateful for your work in this area. Thank you!
Como o Kanye West destruiu uma casa do #TadaoAndo. É surreal:
#Pyxel is a retro inspired #GameEngine for #Python, it’s very impressive!
It’s not hard to generate a static HTML page that loads your game to run on the browser with #pyodide (WASM). And it comes with an assets editor and a #chiptune making tool.
#BolhaPreguiçosa Qual o equivalente brasileiro do Fourthwall / redbubble que permite fazer uma lojinha com camisetas, cacarecos, adesivos, etc. customizados com os seus desenhos?
Sometimes it’s a small thing, it’s a bit jarring when orgs that want to pose as international/global publish some copy/event based on US school terms/seasons. That’s a reminder of how other people are at the periphery and will be probably ignored most of the time. Isn’t it obvious we have different school year arrangements & seasons around the world? I guess @melissawm@melissawm will share my sentiments about this.
I only learned about the .envelope object/propriety in #shapely yesterday, before that I used .bounds (a min/max of points tuple), but envelope is good to know because it provides an easy way of getting the centroid and the area of the bounding box, which can be very useful.
Interactive demo of #shapely’s centroid for the triangle :)

Oi @claromes@claromes, acredito que você manja desses paranauês, dei umas buscas e não encontrei…
Queria saber se as fotos que as pessoas mandam pro Instagram mantém os metadados, se podem conter localização e tal… (desconfio que a Meta guarda a sua localização no momento da postagem e os metadados das fotos para os fins nefastos deles mas publicam uma foto com os metadados removidos, mas não consegui confirmar essa informação)
Se tivesse uma tabela pra eu mostrar pros meus alunos sobre quais serviços fazem o quê com os metadados das fotos ia ser lindo…

In order to publish my personal projects/pages (and most of my teaching materials, hundreds of pages) on #Codeberg, I need to convert #markdown files into #HTML and sprinkle some CSS & JS from a layout template, like #GitHub’s Pages #Jekyll does, but I dread the complexity of installing and tending to Jekyll or Hugo or other static site generators, and I can’t even imagine going near Forejo Actions or any sort of CI intergration.
Should I be brave and do the Jekyll /static generator thing? Any other ideas for poor, overworked, stressed out, clumsy people? :(

Help needed… can the #CodebergPages of #codeberg repos become subdirs of the “main” custom domain?
Currently https://villares.lugaralgum.com is published from a pages repo on https://codeberg.org/villares/pages
Can my /villares/other_repo/ page (from a pages branch I suppose) be published at villares.lugaralgum.com/other_repo ?
(this is how GitHub Pages work by default, can it be replicated on Codeberg?)

What is a #GameEngine for you? Is there a gray area between game engines and graphics frameworks? You can make games with SDL, RayLib, Processing (and py5…), p5js, d3js, but would you consider them game engines?
Maybe I should ask my students to make a game engine purist-neutral-radical alignment chart ? 🤡

Updating my #Processing + #Python tools table:
After some years, things changed and my opinions changed a bit too:
#py5 is going super 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.

So 429: Too Many Requests on my GitHub hosted images, breaking my tutorials etc… Not good!

“Explicando Dados #Geoespaciais em #Python”
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.

Impossible Linux things in my to-do list:
- Fix erratically jumping mouse wheel scrolling on a Dell
- Make a “SysRq key” work so I can do “REISUB” or something, when my computer freezes
I must have spent days (multiples of 24 hours) trying to solve these things and maybe I should just give up.
I suppose that if I had a “Linux experienced” friend by my side these could be solved in minutes, maybe?
Pessoas da comunidade brasileira de #ProgramaçãoCriativa por muitos anos fizeram encontros sob o nome promovido pela Fundação Processing, os chamados #ProcessingCommunityDay, fizemos encontros em várias cidades e então depois de 2020, com a pandemia do COVID-19, fizemos três eventos nacionais muito inspiradores em 2021, 2022 e 2023 (vide https://compoetica.github.io/links/)
Ano passado não conseguimos fazer e este ano pretendemos retomar, só que usando outro nome: #Compoética. Vamos aos poucos divulgar mais sobre o encontro brasileiro de programação criativa em https://compoetica.github.io/CP2025/
Meus agradecimentos profundos ao @guilhermesv@guilhermesv que dedica generosamente um enorme esforço para organizar esses eventos da comunidade e cria o design e peças de comunicação sempre emocionantes de lindos.
