So... I managed to put together some hacky scripts and get out of my dependency on GitHub Pages, I can now publish my stuff elsewhere... now I want to slowly move repos to #codeberg
I'm still thinking on how to preserve the huge number of images from sketch-a-day without burdening the codeberg repo...
Also, I think I want to move my open teaching materials (material-aulas) from this precarious markdown rendering script to something clever and robust like #zensical

#Manjaro help needed! My laptop is old and I'm having trouble updating things because I inadvertently got some Nvidia drivers and I can't find a way of removing them... It seems the main issue comes from this https://archlinux.org/news/nvidia-590-driver-drops-pascal-support-main-packages-switch-to-open-kernel-modules/
And I'm unable to correctly replace the drivers :(

Would you like to get started learning #Python? Or maybe you already know how to code but would like to see something completely different from your current work?
Would it appeal to you to start #drawing stuff, maybe colourful moving, interactive stuff? There is this thing called #CreativeCoding, and you can use a library called #py5
I've written some step-by-step instructions so you can install everything you need, Python, a code editor and py5. Check it out at https://abav.lugaralgum.com/como-instalar-py5/index-EN.html

#GameDev
Indicação de livro do @npub1elh…7vqz: #CodeTheClassics. Parece que são dois volumes, o volume I está oficialmente disponível de graça em PDF https://magpi.raspberrypi.com/books/code-the-classics1, o volume II está disponível "extraoficialmente" em PDF vocês podem imaginar, mas tem o código em https://github.com/raspberrypipress/Code-the-Classics-Vol2 Os textos são incríveis e tem também código #Python recriando os jogos (usando #PyGame, pelo que vi) além dos "assets".
Aproveitando o assunto (que não é a minha especialidade) @npub153c…fp8y comentou que está rolando muito legal a "engine em C" #raylib (https://raylib.com) e, eu se tiver a chance, quero olhar o wrapper em Python #pyray (https://pypi.org/project/raylib/) - tem um outro pyray no PyPI mas esse é o mais ativo e sincronizado com as evoluções da raylib.

poxa, acho que o nome minimalismo foi cooptado pra um monte de coisas né... Na origem, nas artes visuais, deu uns lances que eu curto bastante (Judd) e aí tem gente que aponta influência na arquitetura e eu também vejo coisas legais... De qualquer forma me interessou esse seu comentário ligando o minimalismo a ideia chatonildas... Quando a coisa vira uma imposição meio arbitrária de "tira tudo" é zoado né?

yeah, the pattern in Python is that if the method mutates the object it usually returns None. Like my_list.sort(), in place, and then sorted(my_list), gets you a new list.

2024-12-03 03:05:59 GMT

- reply

these None returning functions are analogous to what we called "procedures" in Pascal, not really functions :)
On the other hand we have nice "comprehensions" borrowed from Haskell. https://docs.python.org/3/howto/functional.html#generator-expressions-and-list-comprehensions
By the way, have you heard of https://coconut-lang.org ?

2024-12-03 01:56:55 GMT

If you are coming to #Python from a language that doesn't have "mappings on your fingertips" you *must* learn about dictionaries (type dict):
https://docs.python.org/3/library/stdtypes.html#mapping-types-dict
(The other 3 essential containers are lists, tuples and sets)

and [@mxfraud](https://tabletop.social/@mxfraud ), thanks! The DH account is good, my brothers pages were at sub-domains of villares.org: joao.villares.org and alberto.d.villares.org. By broken I mean the pages don't load anymore. I think João's page was a WordPress install hosted at DH, and Alberto's was just a redirect to this page: http://www.lugaralgum.com/advn

2024-10-27 17:21:10 GMT

Cash-strapped, I moved one of my domains (villares.org) to the Cloudflare registrar which is cheaper, as a trial... So now I broke the websites I was hosting for my two brothers from my account on dreamhost... I don't have the energy and time to figure out how to make them work again (I suppose it's about DNS/certificates/redirections).
I'd like some help.
I can only offer creative coding lessons/tips/coaching and/or introductory Python lessons/tips/coaching in exchange...
