This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Credit card numbers are in base 10

What if they are generated in base 16, but numbers containing a-f are discarded. Did you think about that? Huh?

[–] LodeMike@lemmy.today 1 points 1 day ago

Yes. The check digit is calculated using base 10

[–] Ziglin@lemmy.world 1 points 1 day ago

Seems to be correct, I was thinking of a different card in my wallet.

Ahem I mean I fancypants McGee have the 16 element identity permutation for my card number!

Everything is in base 10 (unless it's in unary).
