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…

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.

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…
