Yes, this is solve-able #gamedev #noai

An arrow puzzle game with an 100x100 grid filled with twisted arrows in a maze-like pattern. An arrow can be removed if it has a clear escape path to the edge of the grid.

I wrote a #nonogram generator and solver in Python today. Don't ask why :breadpeek: And here is a graph showing the percentage of randomly generated 10x10 nonograms that can be solved without guessing, depending on the density of colored cells. Just because! […] [Original post on chaos.social]

Es ist zwar weder #meermittwoch noch #Fotomontag aber ich habe gerade Lust diese Fotos zu teilen :) 🕐🍂

The beautiful coast of Fira, Santorini, Greece. In the foreground there is a colorfully painted flat roof with white walls and the top half of a large palm tree.

Beach of Kamari, Santorini, Greece. A black sand beach with lots of wooden sunlounes and sun shades made of straw. Large olive trees also provide shade. The beach is almost empty. Very beautiful and idyllic scene.

View from a hotel balcony, you can see the typical small buildings with barrel-shaped roofs, white walls and roofs and blue window shades. Large palm trees provide shade, there is a nice pool and blue ocean and sky in the background.

"Stoßlüften" (Shock ventilation) works. #homeoffice #bme680 #esp32

Three plots showing temperature, humidity and air quality in my home office. There is a sharp decline in both temperature and humidity while ventilating the room, but air quality also drastically improves. After closing the window, temperature recovers way more quickly than humidity and air quality also stays high for a long time. "Stoßlüften" (Shock ventilation) works.
