Tech names should not alias common terminology!

Nowadays you'll search like "bread recipe" and it will turn out "bread" is a JS compiler and a "bread recipe" is its config file. The top results will be 2 billion posts on StackOverflow about that.

Instead of, you know, an *actual recipe for bread*.
Do you have any extremely niche, but serious, ethical stances?

The western literary canon everyone teaches and studies is terrible: mediocre works dominated by crufty white male authors.

Insane to urge kids to read widely when the canon doesn't.

Water is restorative. Water is life. The country rains nourish plants and animals, while the city rains refresh the parched and cleanse pollutants from the air.

Meanwhile, the sun is a nuclear fireball that you cannot even look at. It scorches the earth and burns your very skin.

Just to get us started, here's a thing I wrote about how the 3D rasterization pipeline works.

Also included is a small (single-file, < 300 lines, including comments) implementation in C++, because code is worth 1000 words.

The Raster Graphics Pipeline
This is a high-level but still technical survey of the graphics pipeline.
