Is Ravi & Pat’s 2001 classic on irradiance environment maps missing a factor of 1/pi from Eq. 2? Sure seems that way to me..

The rabid guy with the world’s largest megaphone has Wikipedia in his sights. It’s been a while since I last donated, but I just gave £500. Please consider giving according to your means.

📣 @ec.europa.eu, please force large online retailers to offer consumers choice of courier! Now I have no way to vote with my € and punish liars like UPS, who continue this charade despite having been exposed for it over and over. (Someone was waiting, and I have paid for home delivery. GRRRR.)

@edzitron.com on DeepSeek Good: v3 trained for $5.5m, proving that you don't need to spend half a trillion dollars on new data centers to make great models MIT licensed! Great for running on my own hardware Bad: the CCP influence is genuinely a problem for my uses sherwood.news/tech/a-free-...

Bravo 👏 An analytic theory of creativity in convolutional diffusion models by Kamb & Ganguli I’ve wondered about this very problem for two years now, with wispy intuition that points to exactly this. I never got far into experimentation, let alone theory formation. I wish I had written this paper.

The dimension of the orthogonal group O(n) is n(n-1)/2. That’s a surprising result to me intuitively. The (dangerous as always) low-dimensional intuition would suggest they’d be much more rare.

Gutsy move pushing their own shows like this

Planning to think about what to do next over the holidays? I am hiring postdocs to my group in Helsinki, in combinations of the following: - foundations of (prob) ML - distribution shifts - AI-assistance with computationally rational user models - applications in synthetic biology and biodesign

- Daddy, why is that one spot blue? - Well, son, let me show you how the snow is actually the same color.. I thought it would be a lot longer until I got to teach him color constancy 🥲

Seeing up close the kind of garbage a ~5mbps stream is on my superb 65” LG OLED TV has long made me think increasing the screen resolution is pointless. Sure, the edges are sharp.. Where are the equivalents of audiophiles for video? Stills have film geeks and lovers of great lenses (like me)..

Slang is now officially under open governance at Khronos, and what better way to celebrate than running Slang shaders directly in your browser with WebGPU? try.shader-slang.org You can also compile your shaders to a variety of targets including Metal and HLSL. I'm giddy to finally share this!
