Number of Words: 10104 / Number of Pages: 37
... Introduction
The proliferation of home computers has been accompanied by a corresponding social problem involving the activities of so-called "computer hackers."

... exist.
Alan Turing predicted of NLP in 1950 (Daniel Crevier, 1994, page 9):
"I believe that in about fifty years' time it will be possible to
program computers .... to make them play the imitation game so well that an
average interrogator will not have more than 70 per cent chance of making the
right identification after five minutes of questioning."
But in 1950, the current computer technology was limited. Because of
these limitations, NLP programs of that day focused on exploiting the strengths
the computers did have. For example, a program called SYNTHEX tried to determine

Number of Words: 2495 / Number of Pages: 10
... of computer system can cause as much as harm as any physical hazard.
For example, a cashier in a bank can transfer some money from one of his
customer's account to his own account. Nonetheless, the most dangerous thief
are not those who work with computer every day, but youthful amateurs who
experiment at night --- the hackers.
The term "hacker "may have originated at M.I.T. as students' jargon for
classmates who labored nights in the computer lab. In the beginning, hackers are
not so dangerous at all. They just stole computer time from the university.
However, in the early 1980s, hackers b ...

... a chance to see low flying objects, household
furniture, and even themselves on their PC screen. Just to impress a
neighbour or friend is reason enough to build your own ultrasonic radar
station.
Similar to that of a Polaroid, ultrasonic transducers are used in this
type of radar. A rangefinder emits a brief pulse of high frequency sound
that produces an echo when it hits an object. This echo returns to the
emitter where the time delay is measured and thus the result is displayed.
The Polaroid rangefinder is composed of two different parts. The transducer
(Fig. 1) acts as a microphone and a sp ...

War II and early computer graphics research in the 1960's. In 1965,
computer scientist Ivan Sutherland published a paper describing "The
Ultimate Display" and set the stage for research on the technology of
