su, sudo and sudoku

The words rhyme. Well, rhyming words end in the same phonetic sound. So these can be called anti-rhyming words. (Or would that be the words that don't rhyme??) Or this could be probably viewed as some kind of progression or series of words. What the hell! Let's slog about it..

su - (Substitute User) : This is an unix command which helps user to logon as a different user without logging out. Usually used to login as the root user for admin changes.

sudo - (Super User DO): This unix utility gives users permissions to run some commands as a root user based on the set of constraints enforced by the admin.

sudoku -(Number place): This is the number placing 9x9 matrix that has grabbed the world by horns and has eaten up so many hours of mine and others. It's real, it's addictive, and it's fantastic! Play it here.
