I hate packaging my software for Linux
Nineteen distribution channels later: what it actually costs to give a terminal editor away for free on Linux, and why the next step is a static musl binary that updates itself.

Don't classify, hallucinate
A useful pattern for LLM classification at scale is to let it hallucinate plausible, fake entities. Then resolve to real ones.

Rust SIMD on the GPU
At VectorWare , we are building the first GPU-native software company . Today, we are excited to announce that we can successfully use Rust's portable SIMD ( core::simd ) on the GPU. This milestone marks a significant step towards our vision of enabling developers to write complex, high-performance applications that…

What's the best programming language for coding agents?
This somewhat widely cited post (I keep seeing it cited, anyway) suggests that dynamic languages and/or languages that represent things more concisely are more token efficient. It seems to be cited enough that LLM search results agree. For example, when I searched for "dynamic vs static language token cost" (no…

Retraction: The App Store Rejection of the Week That Was a Correct Rejection
My disdain for astrology is so utter, and my esteem for Godier’s previous work so high, that it simply never occurred to me that he might have actually made and submitted to the App Store an astrology app, let alone that he’d then feign surprise and frustration that an astrology app was rejected for being an astrology…

Super Mario Derivations
One of the most surprising aspects of the Nix language is that it is lazy, especially if you have never used a lazy language before. This laziness is what makes much of Nixpkgs possible, and its complexity.

A shell exclamation mark is not for yelling. Be lazy
Event designators have been hiding in not-so-plain-sight since the late 1970s — so powerful that forgetting might be part of a massive conspiracy to wear out developer keyboards faster than otherwise.
