January 9: Crazy automaton

Build a big fullerene (the dual of an order-6 icosahedral geodesic sphere, I think). Paint its pentagons black and its other faces white (like a soccer ball). Use a simple rule to evolve face colours: re-colour a face black if the subset of the face and its neighbours that are currently black has odd size, white otherwise. The result is a symmetrically evolving series of soccer ball patterns (that appears to repeat after 31 generations).

#genuary 9: crazy automaton. This is kind of reaction diffusiony, where a pixel lives or dies based on its neighbours in the previous frame, but operating on a warped domain. Implemented as a p5.strands shader! https://openprocessing.org/sketch/2843293 #p5v2 #p5

The largest fundamental science agency in Europe will save €1.4 million annually by breaking free from Clavariate Analytics' commercial databases of references and citations.

Starting January 1st 2026, the CNRS will stop subscribing from the Web of Science, along with the Core Collection and Journal Citation Reports.

"We have worked for free to lock ourselves collectively into a paid system", one head of the CNRS explains - but no more! 🎉

Bonus: Dubois' data and visualizations from the early 20th century are available for free on #Github so that anyone can reproduce the infographics, run their own analyses, etc.:

Have a nice Tuesday folks!!

Da lunedì sega circolare (troncatrice) a 149 €:

Non va male, se non dovete fare tagli tipo Matt Cremona (guardatevi i videi e allibite).

Però metteteci una lama Freud¹ da 50 €, che alla fine è quella che fa la differenza, e avrete l'equivalente di ciò che cercano di rifilarvi come "professionale" a 350 o più €.

~~

¹ non la lama che vi psicanalizza mentre tagliate, ma significa "FRese UDine".

January 8: A City. Create a generative metropolis.

This took way too long, but the result is pleasing. Procedurally generated grid of Barcelona-style superblocks, rendered in parallel projection in a pixel art style. (If I had more time, I'd add windows to the facades). Source code at https://editor.p5js.org/isohedral/full/CYwfFZXNA. #genuary #genuary2026

[Edit: These are just blocks, not superblocks. h/t @11011110]

Non boosterò più i quote posts che non aggiungono contesto o valore. Tipo "guardate qui che roba" o "finalmente" o simili.

È onanistico, insensato, da sfigati, distrae, è puro clickbait.

Non tutti hanno le preview o gli snippet attivati. Non aspettatevelo.
