For those interested in physics-based character animation in VR, I can recommend tomorrow's talk by my colleague Joan Llobera where he will detail the contribution from the Artanim Foundation (www.artanim.ch) in the @presencexr.bsky.social Horizon Europe project. Sign up now!
Tomorrow (4th February 2026) I am giving a talk about physics-driven characters for Virtual Reality created with Deep Reinforcement Learning, and what cognitive sciences can learn from these.
If this sounds interesting, you can attend following this link: presence-xr.eu/presence-a-t...
It's free!

Well, that is quite the start to what should be a 24 hour race if I'm not mistaken. But if we're going for a battle royale, this is not a bad start. #daytona24 #imsa

I don’t know if anyone else notices or cares, but when I see a presentation in which the speaker uses obviously generated-AI images to illustrate their slides, it makes me immediately less confident in whatever other content they’re presenting.

![[Scene is a kitchen - a middle aged woman called JANET is boiling peas at the stove. A younger more colourfully dressed woman named LIZ approached her.]
JANET:
Ugh...
LIZ:
What's up?
JANET:
I am so bored of cooking peas!
LIZ:
Have you tried...
AI peas?
JANET:
AI peas?
LIZ:
They're peas with AI!
[Liz holds up to us a packet of peas labelled: Pea-i AI - Peas with AI].
LIZ:
Al-powered peas harness the potential of your peas
JANET:
What
LIZ [Now a voiceover as we cut to a whizzy technology diagram of peas all connected by meaningless dotted lines]
Why not take your peas to the next level with Al Peas' new Al tools to power your peas?
[Show a techno diagram of a pea with a label reading 'AI' pointing to a random zone in it]
LIZ:
Each pea has Al in a way we haven't quite worked out yet but it's fine
[Show Janet and Liz now in a Matrix-style world of peas]
LIZ:
With Al peas you can supercharge productivity and make AI work for your peas!
JANET:
What
LIZ:
Shut up
LIZ:
Our game-changing Pea-Al gives you the freedom to unlock the potential of the power of the future of your peas workflow
From opening the bag of peas
to boiling the peas
to eating the peas
To spending millions on adding Al to the peas and then having to work out what that even means.
JANET:
Is it really necessary to-
LIZ [Grabbing Janet by the collar]:
THE PEAS HAVE GOT AI, JANET
[Cut to an advert ending screen, with the bag of peas and the slogan:
AI PEAS: Just 'Peas' for god's sake buy the AI peas.

My fellow Europeans, I'm once again asking you to write or call your EU representatives and tell them this is unacceptable. They're essentially selling our sensitive data to companies, effectively destroying our privacy and risking our digital well-being.

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
