What Is Complexity in Chess?

news.ycombinator.com Unknown 2025-10-19 16:45:33

Pacto Visual May 2020 an interesting proposal was suggested. I provided some constructive criticism on research paper A Metric of Chess Complexity by FM David Peng, as well as constructive criticism on the codebase used to validate this experiment. For many months I have refrained from further comment, and although code has not progressed, two things have: 1. Public interest in "complexity" as determined by ACPL (yuck). 2. Lichess has a blogging platform where I can properly address deficien

What It's Like to Work at a Body Farm

wired.com Jess Thomson 2025-10-26 11:00:00

Somewhere out in the countryside, hidden behind a copse of trees, are fields full of dead human bodies. These corpses have been strategically laid out in rows, naked as the day they were born, and left to the mercy of the elements until all that’s left of them are bones. It sounds like a scene out of a horror film, but these places are real. They’re called taphonomic research facilities, or sometimes “body farms”—sites where forensic scientists study how the human body decomposes. (Don’t worry,

Playing every game of Wordle simultaneously

news.ycombinator.com Chris K. W. 2025-10-28 05:34:26

If you’ve fallen far enough down the Wordle rabbit hole you may have heard of Quordle, a version of Wordle where you solve four words at once. If you’re looking for more of a challenge, Britannica has you covered with Octordle, where you solve eight words at once. And of course any Wordler worth their salt should be able to handle sixteen words, like in Sedecordle. And no, it doesn’t stop there: Sexaginta-quattuordle isn’t real, it can’t hurt yo– One logical extreme of this trend would be to

Laura Loomer and the limits of posting everything

For all the power she wields with the White House’s affairs, Laura Loomer does not have the traditional tools that her rivals in the MAGA influencer industrial complex have — the highest follower count, the most political power, the most internet platforms, etc. But the fact remains that she’s the influencer responsible for getting Donald Trump to fire over a dozen members of his administration (and counting) for the hazily-defined crime of being disloyal to MAGA.

A gentle introduction to anchor positioning

news.ycombinator.com Unknown 2025-11-21 04:18:55

Anchor positioning allows you to place an element on the page based on where another element is. It makes it easier to create responsive menus and tooltips with less code using only CSS. Here’s how it works. Let’s say you have an avatar in your nav, like this: When you click the avatar, you want a menu to appear right below it. The clicking interaction can be handled with just CSS using the Popover API. But once you click, where does your menu show up? Figuring this out typically requires som

I tried vibe coding in BASIC and it didn't go well

news.ycombinator.com Paul Lefebvre 2026-01-01 04:14:42

With the rise of LLM systems (or “AI” as they are annoyingly called), the term “vibe coding” is all the rage recently. Vibe coding is when you rely almost entirely on these “AI” system to write your code for you via a series of drawn-out conversations. Putting on my cranky old man hat, I find most of it rather frustrating. Now I’m not some retro-sycophant who refuses to use modern tools.

Solving Wordle with uv's dependency resolver

news.ycombinator.com Unknown 2026-01-30 09:28:30

Introduction In a previous life, I wrote a Sudoku solver that relied on Poetry's dependency resolver. We ended up selling that startup to EDB (not because of the Poetry hack), which means that they now own this IP. And, since then, Python packaging has advanced, with uv taking the world by storm. This means that it's time for a refresh. Can we use uv instead of Poetry? And can we solve a Wordle instead of a Sudoku? For the impatient: you can get the solver from my GitHub.

N-Back – A Minimal, Adaptive Dual N-Back Game for Brain Training

Playing the N-Back test is straightforward but requires focused attention. Watch the 3x3 grid as blue squares appear in different positions. Your task is to remember the sequence and identify when the current position matches the one from N steps ago. For a 2-Back test (the standard version), you need to determine if the current square's position matches the position from 2 steps earlier. Click 'Match' or press the spacebar when you detect a match, or click 'No Match' or press 'N' when there's

Scroll snapping, state queries, monster hunter, and gamification

In this (long) part of the customizable select series, it’s all about gamification. In this article, I’d like to highlight one of my demos, where I aimed to recreate a piece of UI found in the Monster Hunter games. To re-create this behavior, I had to think in terms of keyboard navigation first. This demo requires quite a lot of CSS, as well as some scripting, and in the end, I do want to highlight some accessibility concerns.

Last fifty years of integer linear programming: Recent practical advances

news.ycombinator.com François Clautiaux 2026-03-13 13:15:08

Mixed-integer linear programming (MILP) has become a cornerstone of operations research. This is driven by the enhanced efficiency of modern solvers, which can today find globally optimal solutions within seconds for problems that were out of reach a decade ago. The versatility of these solvers allowed successful applications in many areas, such as transportation, logistics, supply chain management, revenue management, finance, telecommunications, and manufacturing.

Despite recent layoffs, Meta is expanding in India

Meta made headlines last month for announcing plans to cut 5% of its employees, controversially deeming them “low performers.” But the job cuts aren’t holding Meta back from expanding in certain geographic areas. Meta is setting up a new site in the country’s tech hub of Bengaluru (formerly known as Bangalore), multiple Meta employees posted on LinkedIn this month. Meta is currently hiring for 41 positions there, according to its careers webpage, most of which were posted over the last month.
