Python: The Optimization Ladder
Python loses every public benchmark by 21-875x. I took the exact problems people use to dunk on Python and climbed every rung of the optimization ladder -- from CPython version upgrades to Rust. Real numbers, real code, real effort costs.

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…

What's new in Emacs 31.1
Emacs 31.1 adds a slew of quality-of-life features. It retires its quirky unexec dumper; there are general improvements to tree-sitter, including a much-wanted auto-installer for grammars; and much more.

My temporary PHP fix from 2014 has nearly 20M installs. Today I'm deprecating it
In 2014 I wrote http_build_url, a temporary PHP polyfill for AOL's CMS. Twelve years and nearly 20 million installs later, I'm deprecating it.

OpenClaw is changing my life
I want to share some thoughts on my recent experience with OpenClaw. Over the past year, I’ve been actively using Claude Code for development. Many people believed AI could already assist with programming—seemingly replacing programmers—but I never felt it brought any revolutionary change to the way I work. Sure…

Idempotency is easy until the second request is different
Idempotency is not just an HTTP header or a key lookup. This article covers the failure cases that bite real APIs: different requests with the same key, concurrent retries, partial success, downstream uncertainty, response replay, expiry, and duplicate message handling.

If you thought code writing speed was your problem you have bigger problems
AI coding tools are optimising the wrong thing and nobody wants to hear it. Writing code was already fast. The bottleneck is everything else: unclear requirements, review queues, terrified deploy…

Should you normalize RGB values by 255 or 256?
Let’s say you’re writing an image processing program. The program takes in an image, converts it to floating point, does some processing and finally saves the modified pixels to disk as 8-bit colors. The question today concerns how exactly the integer-to-float conversion should be done. There are two approaches which…
