The nearest hospital to every place on Earth, in a single S2 range query

For every locality on Earth, how far is the nearest hospital? Naively, that's 437 billion great-circle distances. S2 cell indexing reduces it to a single integer range-join: build the index once, and the answer for every place on Earth comes back in seconds. The same primitive also resolves which country, region, and locality each hospital belongs to, in a single pass over one index.

AI Is Automating the 'Clean Girl' Aesthetic: How Algorithms Are Making 'Effortless' Beauty Data-Driven

Artificial intelligence is reshaping beauty standards by automating the 'clean girl' aesthetic, transforming what once seemed effortless into a data-driven trend. Algorithms now analyze and predict beauty preferences, creating a feedback loop that standardizes minimalist aesthetics across social pla

அலைகளின் ஊடல் : ஃபோரியர்

இயற்கையில் நாம் காணும் அனைத்தும் ஏதோ ஒரு வகையில் அலைகளால் ஆனவை. கடலில் எழும் அலைகள் முதல், நம் காதுகளில் ஒலிக்கும் இசை, கணினியில் நாம் பார்க்கும் காணொளிகள் வரை அனைத்தும் அலைகளின் விளையாட்டுதான். இந்த அலைகளின் பின்னால் இருக்கும் கணித ரகசியத்தை அவிழ்த்தவர்தான் ஜோசப் ஃபோரியர் (Joseph Fourier). இந்த பெயரைக் கேட்டு பள்ளி அல்லது கல்லூரி கணிதவியல் பாடத்தில் பயந்து போனவர்கள் பலபேர் இருப்பார்கள்.…

A computer scientist beat textbook binary search by more than 2x

Binary search is the page-flipping trick everyone learns in their first programming class: to find a word in a sorted list, look at the middle, decide whether your target is in the top or bottom half, and repeat. It has been considered close to optimal since the 1940s. — Read the rest

The Omniscient Algorithms

We live in a society where the algorithms know us better than we know ourselves. They watch what we click, how long we linger, which words make us pause, and what patterns emerge from our choices. In doing so, they build a portrait of us so detailed that it sometimes feels unnervingly intimate, predicting desires … Continue reading The Omniscient Algorithms →

Crypto Faces Increased Threat from Quantum Attacks

The race to transition online security protocols to ones that can’t be cracked by a quantum computer is already on. The algorithms that are commonly used today to protect data online—RSA and elliptic curve cryptography—are uncrackable by supercomputers, but a large enough quantum computer would make quick work of them. There are algorithms secure enough to be out of reach for both classical…

"Catturd" gets more X engagement than the New York Times

Catturd — a right-wing pseudonymous account — routinely outperforms the _New York Times_ on X. The _Times_ has built a following of 53 million accounts, but its posts typically generate a few hundred likes or replies. Nate Silver, the statistician behind FiveThirtyEight and the Silver Bulletin newsletter, tracked X's top engagement accounts for 2026 and found them dominated by low-quality, highly…

Silicon Valley Is Drifting Farther and Farther Right

Silicon Valley’s rising right-wing intelligentsia has plenty of money and a willingness to do the intellectual dirty work of some of the world’s most open reactionaries.

AI isn’t people

"Treating people as things can begin in many ways, but I think one of them is the idea that things can be people. The motivated muddling of categories so prevalent in writing and thinking about AI, beginning with the very name 'artificial intelligence', is intentional and serves the narrative that this software can and will...
