I spent my holidays writing an essay I’d been wanting to write for a year. It captures my struggles and journey over the past few years with the “doom narrative” — and the framework I use to push back and recover. I hope you’ll find it useful.
Happy New Year in advance!

I wrote up what I liked (and what I didn’t) about Codex in a new article. For solo founders, saving a few quid and a few hours each month really adds up — it’s often the difference between shipping and stalling

A little weekend read to share.
Did you know you don’t need an IDE to deploy your MAUI app to a real iOS device?
This started simply because I’m a minimalist — but sometimes automation and saving on license subscriptions can make a real difference to a solo dev.

A little i18n findings from recent work: building for Hong Kong often means bilingual UI. Web usually uses zh-HK; on iOS Cantonese is yue-Hant-HK, Android still zh-HK. Solo founders: want to think about locale tags like this, or just focus on your customers?
