Index 02 — Playground

Playground

Things I build on my own time and leave up for anyone to use. Don't read about them. Play with them. Flip a card for the spec.

The Council

A feature is not done when it ships. It is done when someone says whether it worked.

Rules

The house rules

Karpathy style: it is what it is

Made, shipped, explained

Every playground has the thing itself, how it works, the decisions behind it, and a guide to build your own.

Honest status

Each one says what it runs on: fixture data, recorded runs or live. Nothing pretends.

Mine, not my employer’s

Built on my own time with generic data. No personas, records or data from the day job.
