That's the number 1 and not the letter l

The confusion is everywhere.

Its in passwords, serial #s and unfortunately in software.

I'm talking about the confusion between the letter O and the number 0 as well as the letter l and the number 1.

Time and time again I think we all run into this.

So whenever i'm helping someone setup an account with passwords i'll tell them to stay away from these alphanumerics, or else i'll let them know to annotate with something like (<- that's the number 1 and not the letter l) .

Lets just standardize the number 0 to the slashed version, ∅ .

If you are a coder i'm sure you've wasted lots of hours deciphering programs only to discover the problem was with the confusion between these two numbers and letters.

In code, just write explicit variable names like origin = 200 instead of o0 = 200.

This may seem trivial, but google on this matter and you'll be surprised how often this comes up.
