Clifford Stoll ran a computer system in Berkeley, California. As a system administrator, he kept a close eye on the records. One day, Stoll found something strange in the payment record. There was a 75 cents mistake. One of the thousands of users had used the system for 75 cents worth of time and not paid for it.
