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.
It might sound like very little money to worry about. But that 75 cents was the first clue Stoll had to a much bigger problem--that a hacker had broken into Stoll' s computer system. Who was it？ Stoll spent the next year trying to find out. During that time the hacker used the system in Berkeley as a starting point to break into military computer systems all over the United States.
Stoll had to keep track of the hacker’s activities on the computer without the hacker' s knowing someone was watching him. Stoll even made up huge files of false information so the hacker would have lots to read. When the hacker spent long time reading, the telephone company was able to trace the lines.

Clifford Stoll was a ______.

What is not so widely known is that this special relationship often acts as brake on twins' intellectual development. As they are partly isolated in their own private world, twins communicate less with adults than do other children. The verbal ability of a four-year-old twin is typically six months behind that of a non-twin. The problem can be particularly severe in a deprived home, a one-parent family for example, where there is little stimulation for children anyway.
Such children, while capable of mutual comprehension in a private language, often remain in comprehensible to outsiders and thus at a severe educational disadvantage. The only solution to the problem, cruel though it may seem, is to separate the twins thus forcing them to acquire ordinary speech helped and guided by sympathetic parents and teachers.
