I got tired of inventing i18n keys, so the source

30+ min ago   (293+ words) Most i18n setups ask you to name a string before you have finished writing it. You invent pricing.hero.title, open a JSON file, wire a lookup, then finally type the sentence. Multiply that by a few thousand UI strings and…...

48-Hour Field Notes: Catching a Flake That Only Fails on Someone Else's Machine

48+ min ago   (666+ words) If you have ever re-run a CI job three times hoping for green, you already know why this matters more than another round of guessing. Debugging sessions rot when you start editing source before the failure is repeatable, so I…...

bro.js v2.4.0 - Redis clustering, API key rotation, and a rate limiter that actually survives outages

44+ min ago   (130+ words) Pushed v2.4.0 of bro.js (my zero-boilerplate Express alternative) and figured I'd write up what changed instead of just dumping a changelog. Used to be you had to wire up your own Redis client and babysit connection state. Now you just…...

How to Find the Meaning of Life in 26 Seconds

How to convert JSON to XML in PHP

26+ min ago   (365+ words) If you've ended up here, you probably already know why you need this: some API, some legacy SOAP endpoint, or some client integration only speaks XML, while everything in your PHP app — your database layer, your other APIs, your frontend…...

How I embedded PHP 8.4 runtime directly into Android & iOS apps

24+ min ago   (178+ words) For years, mobile development meant one of two extremes: either go full native (Kotlin/Swift) or pick a heavy JS framework (React Native, Flutter, Cordova/Capacitor) where your mobile app acts as a dumb API client fetching data from a…...

Claude Code Skills Worth Trying: From Vague Idea to Finished Feature

3+ min ago   (1725+ words) I’ve tried out a lot of Claude Code skills, and a few of them are especially useful when you combine them into a workflow. Not because they magically make the model better at coding, but because they help with the…...
