Horses: AI progress is steady. Human equivalence is sudden
So after all these hours talking about AI, in these last five minutes I am going to talk about: horses. Engines, steam engines, were invented in 1700. And what followed was 200 years of steady improvement, with engines getting 20% better a decade. For the first 120 years of that steady improvement, horses didn’t notice […]
The Universal Weight Subspace Hypothesis
Abstract:We show that deep neural networks trained across diverse tasks exhibit remarkably similar low-dimensional parametric subspaces. We provide the first large-scale empirical evidence that demonstrates that neural networks systematically converge to shared spectral subspaces regardless of initialization, task, or domain. Through mode-wise spectral analysis of over 1100 models – including 500 Mistral-7B LoRAs, 500 Vision […]

Delivery Robots Take over Chicago Sidewalks, Sparking Debate and a Petition
LAKEVIEW — The robot revolution is here — on North Side sidewalks, at least. With names like Stacey, Quincy and Rajesh, the boxy food delivery robots are regularly zooming down side streets — and occasionally getting stuck in the snow — to deliver Shake Shack or Taco Bell to eager patrons in Lakeview, Lincoln Park […]
Icons in Menus Everywhere – Send Help
I complained about this on the socials, but I didn’t get it all out of my system. So now I write a blog post. I’ve never liked the philosophy of “put an icon in every menu item by default”. Google Sheets, for example, does this. Go to “File” or “Edit” or “View” and you’ll see […]
Jepsen: NATS 2.12.1
NATS is a popular streaming system. Producers publish messages to streams, and consumers subscribe to those streams, fetching messages from them. Regular NATS streams are allowed to drop messages. However, NATS has a subsystem called JetStream, which uses the Raft consensus algorithm to replicate data among nodes. JetStream promises “at least once” delivery: messages may […]
