Today I shill an old project of mine, unrelated to Nostr: https://github.com/dtonon/papiro
Papiro is a very simple tool for storing any data in physical form by printing qrcodes on one or more pages. I created it a couple of years ago for a personal need; maybe it can be useful to you too to improve your backup strategy. Try it :)
Why QR Codes on paper?Because paper seems the most resilient and cost-effective storage medium on earth, at least for low volume data, and QR Codes have an interesting error-checking system. So it is a nice backup solution to pair with digital ones.
Sounds like an amazing idea, but I'm sick & tired of most people assuming QR Codes are the only real thing out there.
In reality, there are many different codes out there & Aztec is the overall best!
It is TONS more reliable than QR Codes, especially printed out, in the wild.
Error correction works much smoother, etc. It is also more efficient, if I remember correctly.
Thank you for pointing out Aztec, I will reasearch it, maybe it can be added as option!
