Same is true for dates and leading zeros in phone numbers.

Pointing the mirror directly to the Sun would make for a nice temporary light show. A $10B firework. Thanks for the idea. :tu:

% is just a division in disguise. So your code does use division.

Your code does what is known as trial factoring, TF for short. It isn't revolutionary.

Wot?

314159257−82589933 = 231569324

So it is approximately 2231569324 "times massive".

Off by a factor of 2^1e6? :confused:

That is an availability solution, not a backup solution.

The entire drive can die (in a fire, from a passing magnetar, etc.) and it doesn't matter how much local redundancy you had.
