used to describe the work of brilliant students who explored and expanded the

\"hacker ethic.\" Somehow, in the succeeding years, the word has taken on dark
connotations, suggestion the actions of a criminal. What is the hacker ethic,
and does it survive?
ADELAIDE [Day 1, 9:25 A.M.]: the hacker ethic survives, and it is a fraud. It
survives in anyone excited by technology's power to turn many small,
insignificant things into one vast, beautiful thing. It is a fraud because
there is nothing magical about computers that causes a user to undergo
religious conversion and devote himself to the public good. Early automobile
inventors were hackers too. At first the elite drove in luxury. Later
practically everyone had a car. Now we have traffic jams, drunk drivers, air
pollution, and suburban sprawl. The old magic of an automobile occasionally
surfaces, but we possess no delusions that it automatically invades the
consciousness of anyone who sits behind the wheel. Computers are power, and
direct contact with power can bring out the best or worst in a person. It's
tempting to think that everyone exposed to the technology will be grandly
inspired, but, alas, it just ain't so.
BRAND [Day 1, 9:54 A.M.]: The hacker ethic involves several things. One is
avoiding waste; insisting on using idle computer power -- often hacking into a
system to do so, while taking the greatest precautions not to damage the
system. A second goal of many hackers is the free exchange of technical
information. These hackers feel that patent and copyright restrictions slow
down technological advances. A third goal is the advancement of human
knowledge for its own sake. Often this approach is unconventional. People we
call crackers often explore systems and do mischief. The are called hackers by
the press, which doesn't understand the issues.
KK [Day 1, 11:19 A.M.]: The hacker ethic went unnoticed early on because the
explorations of basement tinkerers were very local. Once we all became
connected, the work of these investigations rippled through the world. today
the hacking spirit is alive and kicking in video, satellite TV, and radio. In
some fields they are called chippers, because the modify and peddle altered
chips. Everything that was once said about \"phone phreaks\" can be said about
them too."""
