Base85 contains just about every printable ASCII character, so I’ll use that as a base. 8516 ~= 1031 -> extremely huge, but still feasible at least for state actors. 8520 ~= 1039 -> if I read Wolfram Alpha’s comparison correctly, that is more information than is believed to be contained in the DNA of all living creatures combined. That’s why I’d recommend >= 20 characters.
Yeah, I’d consider anything less than 20 characters broken. Much too likely that it’s contained in a rainbow table, regardless how many special characters you use. Can I remember many 20 character passwords? No, but my password manager can.
As a Linux user and Windows hater, all I can say: That meme is exceptionally stupid. You realize we aren’t in WinXP days?
It approaches positive and negative infinity, depending on the sign of the denominator. The result must not be two different numbers at once, so dividing by zero cannot be defined.
There are other reasons, too, but I forgot about them.
My calculator says they are an “error”.
Sorry bro, if you think JavaScript is difficult, then you’re just too weak.
Not drinking vodka made from radioactive grain is even more safe.
