An interlude about structure computation, SSM and attention. Myosotis: https://t.co/0RXbej9bFm
I hope to tell more in this line of work later. See poster at SPIGM workshop.
This is a picture of what muscle looks like at 25 vs. 55
Left is healthy dense muscle.
Right is unhealthy muscle with fat marbled like a ribeye.
It's called myosteatosis, and for many people, it is already happening.
One study tracked adults aged 74 and older and found that muscle fat increased by 48.5% in men and 29% in women.
As you get older, fat starts to infiltrate the muscle itself.
This can lead to weaker muscles that look the same on the outside, worse insulin sensitivity, a higher risk of falls and fractures, and a faster decline in your 60s, 70s, and 80s.
Your home scale won't catch this. By the time someone feels it, they have already lost years of function.
The good news is that it is reversible. The top four things that move the needle are:
1. The foundation is getting your body metabolically healthy
2. Lifting heavy three times per week so the muscle stays dense.
3. Eating 0.8 to 1 g of protein per pound of body weight
Walking daily
4. Fixing your sleep patterns
You can't out supplement this. The only things that reverse it are lifting heavy things and not being too fat.
From this moment I will unfollow anybody who will mention 1) Karpathy. That’s all! I can tolerate any other topic, even anti Russia opinions, but that one is beyond my tolerance
Once upon a time, King Ptolemy wanted what we’d normally describe as “understanding geometry”—but really, he didn’t want to understand it. He wanted to rule it. He wanted geometry to be his bitch, my young modern friend. So he asked Euclid.
Euclid was a douchebag and started mumbling something like, “If a line cuts two lines and makes the interior angles…,” which didn’t exactly sound like the usual path to becoming king of some mysterious theory. So Ptolemy wondered: was there a simpler way?
And there, under sunlight, all slick with Greek olive oil, Euclid said: “There is no royal road to geometry.”
Usually that’s where the story ends, because we love our fragile mathematicians. But for you, my friend, I’ll tell the real ending. Ptolemy said: “Are you out of your mind? What about the fact that I can prompt ChatGPT-5.2 Pro all day with my pipe dreams about math and post it on Twitter, huh?”
🚀 Excited to share my @GoogleDeepMind student researcher project: Dual-Rate Diffusion✨
⚡ A simple construction that speeds up both regular diffusion and distilled models by interleaving a heavy context encoder with a light conditional denoiser.

🌍Today we release Mosaic, a probabilistic weather model that shifts the Pareto frontier of ML weather forecasting.
It matches the skill of state-of-the-art models while generating a 24-member, 10-day global forecast in under 12 s on a single H100.
