Writing code for any sufficiently large project is just a constant exercise of getting confronted with how poor past you was, even if just days ago. And any current feelings of superiority are bound to be overtaken by reality in mere moments.

Vital piece of investigative reporting from Sky. They've uncovered the X algorithm which feeds users extremist right wing material from the moment they join the site. It is a far-right radicalisation engine, by design.

Toch nog één voordeel van AI-muziek: omdat Suno (cum suis) ook generieke popslop kan maken, moet je als artiest nu echt origineel blijven/worden. Goed voorbeeld:

So, I made a hair shader that doesn't require any specially made meshes or textures.
Initially I made this work by sampling many normal directions rotated around the hair strand direction, but I eventually got an approximation working that doesn't rely on multi-sampling.

It was a weird time, but so much fun though.
GPU computing before CUDA was *weird*.
Memory primitives were graphics shaped, not computer science shaped.
Want to do math on an array? Store it as an RGBA texture.
Fragment Shader for processing. *Paint* the result in a big rectangle.

Fixed a whole bunch of sprite/object drawing behaviours today. Still not passing the acid2 tests, but at least I can play Dr. Mario 😁.
I guess it's on to some more cartridge support to be able to play other games, and trying to pass some more validation roms. #gameboy #emudev #odinlang

Okay, Mario no longer has a split personality, and the Koopas no long moonwalk (which is a good thing). Still some scanline glitches and currently running into some strange issues when trying to support background and object palettes, but that's for another day. #gameboy #emulator #odinlang
