He’s talking about a physical object, something you have on your desk that you can pick up and prove your identity to the person on the other end of the video call.

Reminds me of the ‘totems’ in Inception, except they were to prove to yourself you were not in a dream.

From the github if you were wondering:

Free, open-source, self-hosted wardrobe organizer. Catalog clothes, build outfits, PWA. Docker one-liner deploy.

I think all these measures are designed to slow the flow, spread the storage of the rain across more places so it can cope with the larger downfall in the short-term, buying time for it all to flow away once it has passed.

There are similar ideas in UK with reintroduction of beavers who transform land into spongey floodplains that can tolerate much more rainfall before spilling over.
