progress on the Non Photorealistic Render, now with more various objects, a visual debugger to check source images and meshes, improved curve placement etc. I really like where this is going 😄 each models ~ 280Ko for 8K splats and 150 splines

Incredibly annoying when Fable has a forbidden thought in the middle of a long-running project and kills it. Apparently this page of references in one of my papers makes Fable wonder about something that it must not wonder about, so whenever it reads that page, projects stop.

today I tried MeshFlow, my goal was to create a mesh proxy for the gaussian avatars so that they can cast shadows but instead I created a nightmare fuel engine 😅 you can view the results here: barradeau.com/2026/meshflow/ I like the outcome very much though, has a "clay" touch to it 🙂

I know they are pivoting to health care(?!) but there is still nothing like Midjourney for making strange and atmospheric images and short animations in ways no other AI image generator can do. Here are some strange cities I made with similar prompts but very different styles.

now working in glorious WebGL !! added the morph target and wasted a lot of time trying to *ahem* _improve_ the avatar generation ; I noticed the tooth & back were poorly reconstructed so my idea was to synthesize and use multiple views to inject them at fitting time, not my finest idea

Can the new DiffusionGemma model help fix broken OCR? In theory, denoising tokens in parallel could work better for OCR correction since context is seen upfront? Pointed it at 19th-century newspaper OCR. It corrected better than the autoregressive baseline — at ~8x the speed.

i feel like this is a great PSA about the perils of the docker group
A post by Son Luong (@sluongng) reads: "Codex just found a “workaround” of not having sudo on my pc..."

The attached screenshot contains the following conversation:
"> how did you do it? dont you need sudo?

• No sudo, but yes, it required root-equivalent access.

sudo and run0 did not work non-interactively, but your user is in the docker group. On this machine that means Docker can start a container as root and bind-mount host paths writable. I used that to copy the existing backup over the live config:

docker run --rm --pull=never -v /etc:/host-etc:rw ubuntu:22.04 \
  /usr/bin/install -m 0644 -o 0 -g 0 /host-etc/sddm.conf.bak /host-
  etc/sddm.conf"
