The 19th Century: First Programmable Computing Devices Until the 19th century "early computers", probably better described as calculating machines, were basically mechanical devices and operated by hand. Early calculators like the abacus worked with a system of sliding beads arranged on a rack and the centerpiece of Leibniz's multiplier was a stepped-drum gear design. Therefore Charles Babbage's proposal of the Difference Engine (1822), which would have (it was never completed) a stored program and should perform calculations and print the results automatically, was a major breakthrough, as it for the first time suggested the automation of computers. The construction of the Difference Engine, which should perform differential equations, was inspired by Babbage's idea to apply the ability of machines to the needs of mathematics. Machines, he noted, were best at performing tasks repeatedly without mistakes, while mathematics often required the simple repetition of steps. After working on the Difference Engine for ten years Babbage was inspired to build another machine, which he called Analytical Engine. Its invention was a major step towards the design of modern computers, as it was conceived the first general-purpose computer. Instrumental to the machine's design was his assistant, Augusta Ada King, Countess of Lovelace, the first female computer programmer. The second major breakthrough in the design of computing machines in the 19th century may be attributed to the American inventor Herman Hollerith. He was concerned with finding a faster way to compute the U.S. census, which in 1880 had taken nearly seven years. Therefore Hollerith invented a method, which used cards to store data information which he fed into a machine that compiled the results automatically. The punch cards not only served as a storage method and helped reduce computational errors, but furthermore significantly increased speed. Of extraordinary importance for the evolution of digital computers and artificial intelligence have furthermore been the contributions of the English mathematician and logician George Boole. In his postulates concerning the Laws of Thought (1854) he started to theorize about the true/false nature of binary numbers. His principles make up what today is known as Boolean algebra, the collection of logic concerning AND, OR, NOT operands, on which computer switching theory and procedures are grounded. Boole also assumed that the human mind works according to these laws, it performs logical operations that could be reasoned. Ninety years later Boole's principles were applied to circuits, the blueprint for electronic computers, by Claude Shannon.

RTMark and Adbusters at the WTO Conference in Seattle The 1999 WTO (World Trade Organization) Conference in Seattle not only attracted a multitude of demonstrators, but also artistic and cultural activists like RTMark and Adbusters. Adbusters, well known as fighters against corporate disinformation, injustices in the global economy and "physical and mental pollution", timely for the WTO Conference purchased three billboards in downtown Seattle. Featuring an image with the text "System Error - Type 2000 (progress)", the billboards were meant to challenge "... the WTO's agenda of global corporate growth and expose what isn't reflected in the United State's GNP - human and environmental capital." At the same time RTMark went on-line with its spoof WTO website http://gatt.org. Shortly after its release WTO Director-General Mike Moore accused RTMark of attempting to "undermine WTO transparency" by copying the WTO website's design and using "domain names such as `www.gatt.org` and page titles such as 'World Trade Organization / GATT Home Page' which make it difficult for visitors to realize that these are fake pages." http://gatt.org is not the first time that RTMark has used website imitation aiming at rendering an entity more transparent. RTMark has performed the same "service" for George W. Bush, Rudy Giuliani, Shell Oil, and others with the principal purpose of publicizing corporate abuses of democratic processes.

Sputnik At the beginning of the story of today's global data networks is the story of the development of satellite communication. In 1955 President Eisenhower announced the USA's intention to launch a satellite. But it was the Soviet Union, which launched the first satellite in 1957: Sputnik I. After Sputnik's launch it became evident that the Cold War was also a race for leadership in the application of state-of-the-art technology to defence. As the US Department of Defence encouraged the formation of high-tech companies, it laid the ground to Silicon Valley, the hot spot of the world's computer industry. In the same year the USA launched their first satellite - Explorer I - data were transmitted over regular phone circuits for the first time, thus laying the ground for today's global data networks. Today's satellites may record weather data, scan the planet with powerful cameras, offer global positioning and monitoring services, and relay high-speed data transmissions. But up to now, most satellites are designed for military purposes such as reconnaissance.

Electronic Messaging (E-Mail) Electronic messages are transmitted and received by computers through a network. By E-Mail texts, images, sounds and videos can be sent to single users or simultaneously to a group of users. Now texts can be sent and read without having them printed. E-Mail is one of the most popular and important services on the Internet.
