The chart classifies programming paradigms according to their kernel languages. Kernel languages are ordered according to the creative extension principle: a new concept is added when it cannot be encoded with only local transformations. Two languages that implement the same paradigm can nevertheless have very…

How Postgres’ concurrency model coupled with long-lived transactions can degrade the performance of indexes on hot tables in your database.
This post is a work in progress.Inspired by a recent purchase of the Red Book, which providesa curated list of important papers around database systems, I’ve decidedto begin assembling a list of im...
Technical articles by Kevin Menard. Topics include Ruby, Java, machine learning, and general computing.
I've finally implemented the command I keep typing all day: gti. It's a program that displays a badly made ASCII-art animation to punish you for your typing error - and after that magically launches the command you meant to launch. The code is available under an MIT-like license on github - though of course anybody…
Lil is part of the technology that powers Decker , a multimedia creative tool inspired by HyperCard . Decker uses Lil for adding custom behavior to decks and the widgets within. Lil is designed to be learned in layers, but it is a richly multi-paradigm language which incorporates ideas from imperative, functional…

I often write pieces that showcase how well Rust can work for you, and how it can let you build powerful abstractions, and prevents you from making a bunch of mistakes. If you read something like S...

Signed integers are not allowed to overflow in C and C++, and this helps compilers generate better code. I was interested in how GCC is tak...

Modern extension to classic 2003 article by Joel Spolsky
A deep dive into graphics APIs, shader languages and GPU architecture, exploring a simpler design for modern hardware. By Sebastian Aaltonen.
Over two years ago, in one of my first public talks about Ghostty , I shared my vision for libghostty : an embeddable library for any application to embed their own fully functional, modern, and fast terminal emulator. Libghostty is finally starting to take shape, and I'm excited to share more details about my plans…

I build shaders, renderers, games, and other stuff that's fun to stare at.
I’ve spent the last year building keyboards , which has included writing firmware for a variety custom circuit boards.
In this post I’ll show you how I found a zeroday vulnerability in the Linux kernel using OpenAI’s o3 model. I found the vulnerability with nothing more complicated than the o3 API ̵…
Two years ago, I had a blog entry describing falling in love with Rust . Of course, a relationship with a technology is like any other relationship: as novelty and infatuation wears off, it can get on a longer term (and often more realistic and subdued) footing – or it can begin to fray. So well one might ask: how is…
I enjoy reading a lot of source code and after 15 years in the field I feel like I have seen my fair share. Even with a full-time job, I still try to spare evenings here and there to read. I don't see myself ever stopping. It is always an opportunity to learn new things to follow somebody's mind process. Every once in…
You can use of UUIDs as the primary key to avoid database scale problems. But should you? I propose an alternative.
I don’t like people adding tracking stuff to URLs. Still less do I like people adding tracking stuff to my URLs.
Every lisp hacker I ever met, myself included, thought that all those brackets in Lisp were off-putting and weird. At first, of course. Soon after we all came to the same epiphany: lisp’s power lies in those brackets ! In this essay, we’ll go on a journey to that epiphany.
Yesterday Andres Freund emailed oss-security@ informing the community of the discovery of a backdoor in xz/liblzma, which affected OpenSSH server (huge respect for noticing and investigating this). Andres' email is an amazing summary of the whole drama, so I'll skip that. While admittedly most juicy and interesting…
