What Happens When SSS Meets Blue Noise: Super-Exponential Light Transport
When subsurface scattering (SSS) is driven by a blue-noise distribution, classical light transport breaks down. Light no longer decays exponentially according to the traditional Beer-Lambert law.

cynical take - 1mil at 70USD is 70 mil. chop off 30% for platform fees, now we're 49mil. Assume the publisher is 100% recoup, that's 9 mil. Then the split after... let's be GENEROUS and say 50/50. Final income for 1mil sales is: * $4.5mil for studio * $44.5mil for pub * $21mil for platform holders

This has major implications for #longCOVID in healthcare and education, given the way hospitals and schools have mismanaged aerosol transmission of infectious diseases. Turns out basing policy on misinformation that has been out of date for nearly a century was a bad idea. Quelle surprise!

All currently available SSS models ignore internal boundary condition (aka TIR) .. but trapping rays past the critical angle (keeping'em bouncing) forces longer path lengths .. for richer, more saturated, physically accurate translucency. Same color and mfp. With / without TIR

The heavy burden of energy prices. I hear politicians saying that all the time. It sounds like brainwashing – isn’t it rather the case that people and businesses are mostly burdened by their dependence on fossil fuels and inefficiency?

This is SUCH an excellent account of this moment in both informational and emotional terms.
Screengrab, text:
"This week was an abattoir for dreams. Every day, the same breathless churn of opinion. Every day, more rumours and innuendo, more gossip, more unconfirmed reports and best guesses. Ceaseless baseless noise and gibberish. And then behind it all, past the cameras and the news reports and the resignation letters, just this one screaming thought in your head: You’re fucking it up. You’re fucking it up. You’re fucking it up.

This is our one chance and you’re fucking it up."

Gaussian splats are really cool tech, but I don’t understand why people classify it as AI. It’s point clouds with a ML optimizer; all “classical” stuff. Sure, genAI can generate Gaussian splat clouds now, but that’d be like saying JPG and TXT files are AI because genAI can make JPGs and text too.

This Lippmann-Dewey debate still frames democratic thinking today. Do we fix democracy by improving the expert infrastructure that informs the public? Or by improving the public's own capacity to participate? The answer, I'd argue, is both.

Walter Lippmann wrote Public Opinion in 1922. His core insight: the world is too complex for any of us to experience directly. We can't personally verify what's happening in government, the economy, or foreign affairs. So how do we form opinions about them?

Today in AI: Canada rejected the PR application of a McMaster postdoc from the Sorbonne who works in the immunology of aging because the generative AI being used to process applications (😱) entirely hallucinated her credentials. Everyone involved should be fired. archive.is/ELrCI#select...
Kémy Adé was shocked by the immigration refusal letter she received.
In rejecting her permanent residence application, the Immigration Department cited her current job duties, which included wiring and assembling control circuits, building control and robot panels, programming and troubleshooting. The department said these duties didn’t match the Canadian work experience she claimed.
Well, no, they didn’t. Adé is a post-doctoral research fellow and guest teacher at McMaster University — and those skills are not part of her repertoire. Nor are they what she submitted in her immigration application a year ago.
“I saw this language about this job description that has nothing to do with me,” said the health scientist from France, who has a PhD from Sorbonne University in the immunology of aging. “I was disoriented how this could happen.”
But a disclaimer at the bottom of the refusal letter might provide a hint.
It’s believed to be the first time that the department explicitly referred to the use of generative AI to support application processing in immigration refusals. The disclaimer also noted that all generated content was verified by an officer and that generative AI was not used to make or recommend a decision.
