@bsletten Have you seen Kneecap? I think you would appreciate it. I knew nothing going in and I recommend it that way (just be prepared for a whole lot of profanity, drugs, sex, violence, and Irish politics… okay, so knowing a *little* Irish politics helps). It’s entirely unique; absurd, serious, and a lot more self-aware than it seems at first glance.

You lost 10%. You lost another 10%. Wait, now you've gained 10% - and now you've gained another 11%!

How much did you gain total?

Wrong. You lost 1.1%.

(This has either been about performance optimizations or about stocks)

It's amazing how 3DGS rendering found a local minimum nearly right out of the gate. Plenty of improvements on the training side, but the core rendering pipeline is mostly still nearly identical to the original paper.

Case in point, I got carried away and used claude to try out a few experiments to reducing popping: a hybrid sorting + mini-OIT, and blending splats which overlap along the viewing direction. Neither panned out, but satisfying to try.

Claude code + opus 4.5 was a big help in getting that done by helping with the drudgery -- creating evaluation apps and one-off experiments, even porting over other renderers to compare results apples-to-apples.

Hobby projects are a lot more fun when you can just do the interesting part and not have to dread the grunt work quite so much, especially when the grunt work doesn’t see the light of day.

After leaving it alone for too long, finally knocked off a few of my top todo items for MetalSplatter (my OSS 3DGS renderer for Vision Pro / iOS etc) -- Swift 6 and modern concurrency cleanup, a chunked data model, and (finally) spherical harmonics

Coming across random MetalSplatter sightings in the wild never gets old. https://x.com/timd_ca/status/2000760184226943167

New paper from Apple - Sharp Monocular View Synthesis in Less than a Second Mescheder et al. @ Apple just released a very impressive paper (congrats! 🎉🥳). You give it an image and it generates a really great looking 3d Gaussian representation. Uses depth pro. It's really good.

Just so I'm clear:

Hungry (adj.): a strong, visible drive to get what you want. Good.
Thirsty (adj.): a strong, visible drive to get what you want. Bad.

I guess the lesson is to be socially acceptable you should start by eating too little and drinking too much?

But I do feel that this confluence of inflection points mean that every individual’s actions have a uniquely powerful impact on the world. We may feel powerless, but perhaps never in human history have we each had as much power to shape the future as we do right now. [2/2]

Between AI, MAGA, and climate change, it feels like the world’s at a tipping point on several different scales, all converging at once. It’s an overwhelming time to be living through, and feels unique — at least in my lifetime, but it’s hard to be objective from the inside looking out. I don’t know if this is the Singularity, or an extinction event, or just the Interesting Times that every generation on Earth feels they are living through. [1/2]
