🔗 Finds #26

Hello everyone, and welcome to issue #26 of Finds — the articles, sites, and corners of the web I bookmarked this week:

📄 Articles

norvig.comSolving Every Sudoku PuzzlePeter Norvig's 2006 essay: constraint propagation to narrow the grid, depth-first search for whatever's left, in about a hundred lines of Python. It clears 95 hard puzzles at 0.04 seconds each — but one random puzzle took 1,439 seconds, a thousand standard deviations off the mean.

mathpages.comPowers of Primes Dividing Factorials — Legendre's formula for how far a prime divides n!: subtract the base-p digit sum of n, divide by p−1. The same identity reappears in binomial coefficients, where the prime's exponent measures exactly how badly digit-summing fails to distribute over addition.

🌐 Websites / blogs

gwern.netGwern.netGwern Branwen's essays on AI scaling, spaced repetition, darknet markets, and blinded self-experiments run on his own sleep. Every piece carries a status and a confidence rating, and the site is built around sidenotes and link popups instead of footnotes you lose your place in.

w3schools.comW3Schools — CSS TutorialThe internet's default first stop for CSS, running from selectors through flexbox, grid, and animations. Over 700 examples, and every one of them opens in an editor where you change the CSS and press run to see what breaks.

📚 From Wikipedia

en.wikipedia.orgCut of beef — How a carcass gets divided, and how little the countries agree — 'brisket' means one thing in the US and something else in the UK, and Brazil numbers its cuts. The principle underneath all of them: meat gets more tender the further it sits from hoof and horn.

📺 From YouTube

youtube.comClair Obscur: Expedition 33 Re-edit (Series) — Re-edit Studios cut the game's cutscenes into 16 episodes of about 20 minutes, restructured as television rather than a cutscene compilation. If you're never going to play it, this is how you get the story.

📺 Completed

en.wikipedia.orgLink Click (Seasons 1 & 2) — 7.5/10 — A photo studio where one operator dives into a photograph and spends twelve hours inside the photographer's body, retrieving whatever the client lost. One trip per picture, no second attempt, and nothing in the past may change — a rule the show spends two seasons making hurt.

🌱 Promoted to the wiki: these now live on their topic pages — Computer Science, Mathematics, Blogs, Web Development, Food, Games, and Anime — so they’re easy to find later. 🗂️ Catch up on past issues.
