Suppose you want to search for a list of words. If you’re using grep, you can add the -f flag provide a file of regular expressions, and you can add the -F to tell it that the regular expressions are in fact just words. I did something like this a couple days ago when searching […]

Squares, high and low Let p be an odd prime number. Then half the numbers from 1 through p − 1 are squares and half are not. That is, for half of numbers 1 ≤ k < p, the equation x² = k mod p has a solution. The traditional name for these numbers is […]

AI Mania Is Eviscerating Global Decision-Making Here's an entertaining perspective from Nik Suresh on the AI mania that is overwhelming the large companies that he consults with. It's crammed with spicy anecdotes from anonymous sources. In one extreme case, I have seen an e...

In Rewriting Bun in Rust Jarred Sumner made the following claim: Claude Code v2.1.181 (released June 17th) and later use the Rust port of Bun. Startup got 10% faster on Linux but otherwise, barely anyone noticed. Boring is good. I decided to have a poke at my own Claude Co...

Here’s the big idea in Keith Johnstone’s book Impro: Children are naturally creative, but are violently formed into repressed adults by Western culture and education The process of becoming more creative and expressive is largely a process of unlearning these habits of repr...

Tool: SQLite Query Explainer

Julia Evan's, in Learning a few things about running SQLite:

Maybe one day I’ll learn to read a query plan.

Big same.... which inspired me to have Fable build this interactive explain tool, which runs SQLite in Python in Pyodide in Web Assembly in the browser and adds a layer of explanation to the results of both EXPLAIN and EXPLAIN QUERY PLAN.

Approach with caution, since I don't know enough about SQLite query plans to verify the results myself, but it seems cromulent enough to me.

There are two wolves inside of me, lol. Some days I want to be a “designer”. Other days I want to be a “developer”. On the days I find myself wanting to feed the developer, it’s often because making something “work” seems easier (and more impressive) than making something “g...

I’m going to be the weirdo who complains about literally getting free stuff.

Releases, advisories, and articles from across the package management world

A setback for California Forever, a $500 million artillery shell plant not producing any shells, the difficulty of recycling EV batteries, manufacturing wire harnesses, and more.

I'm pretty sure this book is a psyop designed to demoralise a generation of starry-eyed dreamers. It is obviously written by the same people who told us not to land on Europa. A malignant energy designed to limit the scope of human ambition and thwart our plans to colonise the universe. The problem is, I can't find fault with any of their logic. The Weinersmiths make a compelling case that…

A certain vintage if Python web nerd might be delighted to learn that the most recent commit to the Quixote web framework was six hours ago.

The oldest commit in that repo is from 21 years ago, and that was the initial import of Quixote 2.4 from Subversion into Git.

Tool: LLM cliché highlighter

I got frustrated reading yet another article that was crammed with the clichés of LLM-generated writing - "no fluff, no filler, no jargon" type stuff - so I had Fable 5 vibe code up this app for highlighting ten common patterns that show up in that sort of writing.

One of the cool features of JPEG files is that there's the option to save low frequency components first. This means that a partially downloaded image will be displayed at low resolution instead of being cut off. In the file, this works by breaking up the compressed data...

The anonymous blogger Gwern recently completed a thirteen thousand word post called Human-like Neural Nets by Catapulting, in which he offers a theory about why LLMs don’t possess truly flexible human-like intelligence, and how we might train LLMs that do. Theories like this...

When a really long road ends, why don’t we do more to celebrate the staggering amount of collective work that went into it? The ancient Romans really outclassed the federal highway system on this front.

One command, six repos, three standards bodies, an advisory database, and a version comparator written in the wrong language.

Quick follow up to the previous two posts on ICD-10 codes and HCPCS codes. This post uses Python’s squarify library to create treemaps visualizing how many codes begin with each letter. Here’s the treemap for HCPCS codes. And here’s the treemap for ICD-10 codes. The sizes of the squares are proportional to the number of […]

This article tells part of the story of Maxis Software. Maxis came into 1994 riding high on the wings of SimCity 2000, the hit of the previous holiday season. They followed up that success with… SimHealth: The National Health Care Simulation. This may sound like satire, but it was all too real. To be clear, SimHealth was […]
