Claude shannon founds information theory and coins the term bit. The first sited computer virus was detected in 1971 and was called the creeper virus. A computer virus is a program, script, or macro designed to cause damage, steal personal information, modify data, send email, display messages, or some combination of these actions when the virus is executed, it spreads by copying itself into or over data files, programs, or boot sector of a computers hard drive, or potentially anything else writable.

In actual fact, the lecture was fairly entertaining from a historical. The theoretical underpinning of self reproducing automata i. Now one can create selfreproducing automata that are not computer viruses. Spyware development and analysis publish your masters. The conclusion is drawn that although the capacity for universal construction is a sufficient condition for selfreproduction, it is not a necessary condition.

Selfreproducing automata and the impossibility of seti. The scope of the spectacle has thus increased in the past decades with the proliferation of new media and social networking like facebook, youtube, twitter, instagram, skype, and so on, which increase the scope and participation of the spectacle, and make debords concept of the spectacle all the more relevant in the contemporary era.

See also the timeline of artificial intelligence and the timeline of cyberculture and hacker culture and, for pictures of the machines, the visual history of computing 1859. Everyone knows that a machine tool is more complicated than the elements which can be made with it, and that, generally speaking, an automaton a, which can make an automaton b, must contain a complete description of b, and also rules on how to behave while. It was designed in the 1940s, without the use of a computer.
