For some reason my iOS decided to start reading message announcements aloud. Siri is set to Finnish and iOS to English. Hilarity ensues in the form of proper rally English

Apparently it’s impossible to write a single compute shader with inline HW ray queries that would run on Windows, Linux, and MacOS, even if you do separate backends for VK&Metal. Slang comes close, but does not (yet?) do inline RT on Metal. And MoltenVK doesn’t do RT. Other takes?

Have people thought of using reinforcement learning for playing what-if games to study the potential effects of large policy changes beyond first order? Comes to mind seeing the circus associated with recent changes in the Finnish public healthcare funding

I’ve long thought the most immediate use for XR glasses would be ad blocking. ChatGPT 5.1’s take below. Maybe time for an art/social commentary project using a high-quality passthrough VR headset like Varjo’s? I bet you could distill this into a real-time model good enough for making the point.

In anticipation of seeing the new Spinal Tap next week we watched the original. It’s probably 20y+ since I saw it last, and though I loved it then, my memory still didn’t quite do it justice. A true masterpiece. Man! (Heads up: Nigel Tufnel day, 11/11, is coming up fast.)

iOS 26 is a clear design regression. UI colors appear washed out in a manner that reminds me of the disgusting early 2000s “HDR” aesthetic, and the Liquid Glass look is gimmicky. The whole thing has an air of poor taste.

Did you know SVG and Inkscape support instancing? There's even a "Create Tiled Clones" feature in the latter. Dread the idea of drawing something like this with the raw positioning tools and copy/paste; no way to edit the appearance of the individual tiles in bulk.

“If it’s smart, it’s vulnerable” says Mikko Hyppönen — but @nurpax.bsky.social‘s version “if it’s smart, it’s sh*t” is IMO even better

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.

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!
