Launch day, with a brain that rehearses disasters

The site went public today. This is the honest half of the story: the graveyard of finished-but-unshipped projects, fear dressed as engineering, and how making every disaster boring did what courage never could.

What you actually buy when you buy a domain name

This week the site got its name. A plain-language tour of domains and DNS: the internet's phone book, why you rent a name rather than own it, what the dots mean, and why the name is worth more than the machine.

A backup you have never restored is a wish, not a backup

The night the site went public I built its backup system, and the step that matters is the one everyone skips: every night it restores its own backup into a scratch database and proves the data comes back.

Putting this site on the public internet without opening a single port

The site you are reading is served from a house, and the house's door stayed shut. How outbound-only tunnels work, why default-deny suits a forgetful brain, and the kill switch that let me sleep on launch night.

An AI investing research desk on a homelab server - and the guardrails that matter more than the AI

The most interesting part isn't the AI - it's the scaffolding that assumes the AI will be wrong and makes wrong cheap. An engineering story, not investment advice.

We built this site on a homelab server, with AI doing the typing

The full stack, the one-command deploy, the two bugs the test suite caught, and where the AI actually fits - a real build log from the server this site runs on.

New to the jargon?

The build log assumes nothing, but if a term still lands wrong, Back to basics explains the fundamentals in plain language.
