Like this product, there are many other products that focus on allowing one to back-up crypto-currency wallet seed phrases. However, they all have in common the following major dis…

Please see my reply to this other similar question: > Looks like a new 2d barcode format to me. Why I would want this rather QR or any other that have redundancy built in? https://…

Initially the bits were counted from 0, however this had two issues: * using 0 as starting point would immediately trigger one's "computer science" instinct, and then it's uncertai…

With regard to the puzzle idea: if the secret is quite sensitive, and assuming you split the card in say 4 parts, then coercing 2 of them to reveal their puzzle pieces, would reduc…

The only one minor issue with this snippet (which I now just realized), is that if the secret has the first few bits on zero (i.e. anything that starts with something under `7`) th…

> Cool but wouldn’t you forget how to decode it after some time? Not necessarily. First of all there isn't much decoding to be done: if one follows the recommendation, and one uses…

If the CNC machine is not connected to a network, and (I don't know much about CNC, but I do wonder) if one can provide a generic program, then just fill in the parameters before e…

This is how much I could pack on a standard (CR80 ID) card sized plate, while still being able to punch the holes without power (or precision) tools. (The aspect of ease of creatio…

There is: * press `reset` (to clear the checkboxes); * press `tab` (to select the first checkbox); * if the current bit is `1` (i.e. there is a hole in the pattern), press `space`;…

Indeed, this is another use case I've had in mind. (Protect a X25519 private key, and use the public key to encrypt against, without the need to have the private one online.) Howev…

Besides the issue with printing and paper longevity, another issue with QRCodes is that you can't easily convert them back to data without a proper application that implements the …

Provided that the information one wants to keep safe is sensitive and important long term, there are two main issues with printing (either text, QRCode, or anything): * (paranoia) …

Software performance, which translates into CPU/memory/disk resources, are only one aspect of the costs incurred by crawling bots, and fall under the unmetered / virtually infinite…

I don't see how respecting one's rights (in this case one's copyright over his own works) leads to having revoked the right to buy books. I agree that it is sad to see many online …
