So from a list of 117 million email addresses I have calculated the frequency of occurrence of each character and for each, noted which keys lie closest on the keyboard, and factored in the likelihood that a mis-stroke will create an invalid email address.We got chatting and it turns out she only lives a few blocks from me and also collects vintage cameras; we’re playing golf next week.
