The closer we look at time, the stranger it gets
The nature of time is one of the most profound and longstanding problems in physics – one that no one can agree on. From our perspective, time seems to steadily progress forward with each tick of the clock. But the closer we look, the more bizarre time becomes – from equations that state time should […]

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 […]
Manual: Spaces
Space (whitespace) is a whole group of glyphs, one of the most important and frequently-used. Any computer user knows space as the widest key on their keyboard, however the notion itself is much bigger and comprises multiple important typographic terms and ideas. Space in general is a blank unprinted area, a counterform that separates letters, words, lines etc. In typography, there are several types of spaces: sinkage (space […]

Listen to the article 4 min This audio is auto-generated. Please let us know if you have feedback. Kroger’s announcement on Tuesday that it will shutter three of its robotic e-commerce fulfillment facilities represents a sharp turnabout for the grocery company, which until recently had expressed confidence in its ability to leverage automation to run […]
Why the Sanitizer API is just `setHTML()`
Sanitizing HTML is the practice of taking a piece of HTML and removing some unwanted elements and attributes. Most often this is done to allow user-generated content with HTML but without causing XSS bugs. When imported from a library, a sanitizer typically looks like this: const clean = DOMPurify.sanitize(input); context.innerHTML = clean; However, the API […]
