Encoding 64bit user ids in 8 chars
It's me again. My app requires search queries containing a maximal number of "from:" parameters. I need to give my users this number. Right now, owing to variable username and user id lengths, I can only tell them an approximate number.
Would it be possible to have a 8 char encoding of the 64bit user ids? Then I could tell my users that the number is 56 exactly, instead of an arbitrary number confusingly dependent on username and user id length.
Many thanks in advance,
