1940s - 1950s: The Development of Early Robotics Technology

During the 1940s and 1950s two major developments enabled the design of modern robots. Robotics generally is based on two related technologies: numerical control and teleoperators.

Numerical control was invented during the late 1940s and early 1950s. It is a method of controlling machine tool axes by means of numbers that have been coded on media. The first numerical control machine was presented in 1952 at the Massachusetts Institute of Technology (MIT), whose subsequent research led to the development of APT (Automatically Programmed Tools). APT, a language for programming machine tools, was designed for use in computer-assisted manufacturing (CAM).

First teleoperators were developed in the early 1940s. Teleoperators are mechanical manipulators which are controlled by a human from a remote location. In its typical application a human moves a mechanical arm and hand with its moves being duplicated at another location.

Late 1970s - Present: Fourth Generation Computers

Following the invention of the first integrated circuits always more and more components could be fitted onto one chip. LSI (Large Scale Integration) was followed by VLSI (Very Large Scale Integration) and ULSI (Ultra-Large Scale Integration), which increased the number of components squeezed onto one chip into the millions and helped diminish the size as well as the price of computers. The new chips took the idea of the integrated circuit one step further as they allowed to manufacture one microprocessor which could then be programmed to meet any number of demands.

Also, ensuing the introduction of the minicomputer in the mid 1970s by the early 1980s a market for personal computers (PC) was established. As computers had become easier to use and cheaper they were no longer mainly utilized in offices and manufacturing, but also by the average consumer. Therefore the number of personal computers in use more than doubled from 2 million in 1981 to 5.5 million in 1982. Ten years later, 65 million PCs were being used.

Further developments included the creation of mobile computers (laptops and palmtops) and especially networking technology. While mainframes shared time with many terminals for many applications, networking allowed individual computers to form electronic co-operations. LANs (Local Area Network) permitted computers to share memory space, information, software and communicate with each other. Although already LANs could reach enormous proportions with the invention of the Internet an information and communication-network on a global basis was established for the first time.

Racism on the Internet

The internet can be regarded as a mirror of the variety of interests, attitudes and needs of human kind. Propaganda and disinformation in that way have to be part of it, whether they struggle for something good or evil. But the classifications do no longer function.
During the last years the internet opened up a new source for racism as it can be difficult to find the person who gave a certain message into the net. The anarchy of the internet provides racists with a lot of possibilities to reach people which they do not possess in other media, for legal and other reasons.

In the 1980s racist groups used mailboxes to communicate on an international level; the first ones to do so were supposedly the Ku Klux Klan and mailboxes like the Aryan Nations Liberty Net. In the meantime those mailboxes can be found in the internet. In 1997 about 600 extreme right websites were in the net, the number is growing, most of them coming from the USA. The shocking element is not the number of racist pages, because still it is a very small number compared to the variety of millions of pages one can find in this media, it is the evidence of intentional disinformation, the language and the hatred that makes it dangerous.
A complete network of anti-racist organizations, including a high number of websites are fighting against racism. For example:

The "Corpse-Conversion Factory"-rumor

Supposedly the most famous British atrocity story concerning the Germans during World War I was the "Corpse-Conversion Factory"-rumor; it was said the Germans produced soap out of corpses. A story, which got so well believed that it was repeated for years - without a clear evidence of reality at that time. (Taylor, Munitions of the Mind, p.180)

Anonymity

"Freedom of anonymous speech is an essential component of free speech."

Ian Goldberg/David Wagner, TAZ Servers and the Rewebber Network: Enabling Anonymous Publishing on the World Wide Web, in: First Monday 3,4, 1999

Someone wants to hide one's identity, to remain anonymous, if s/he fears to be holding accountable for something, say, a publication, that is considered to be prohibited. Anonymous publishing has a long tradition in European history. Writers of erotic literature or pamphlets, e. g., preferred to use pseudonyms or publish anonymously. During the Enlightenment books as d'Alembert's and Diderot's famous Encyclopaedia were printed and distributed secretly. Today Book Locker, a company selling electronic books, renews this tradition by allowing to post writings anonymously, to publish without the threat of being perishing for it. Sometimes anonymity is a precondition for reporting human rights abuses. For example, investigative journalists and regime critics may rely on anonymity. But we do not have to look that far; even you might need or use anonymity sometimes, say, when you are a woman wanting to avoid sexual harassment in chat rooms.

The original design of the Net, as far as it is preserved, offers a relatively high degree of privacy, because due to the client-server model all what is known about you is a report of the machine from which information was, respectively is requested. But this design of the Net interferes with the wish of corporations to know you, even to know more about you than you want them to know. What is euphemistically called customer relationship management systems means the collection, compilation and analysis of personal information about you by others.

In 1997 America Online member Timothy McVeigh, a Navy employee, made his homosexuality publicly known in a short autobiographical sketch. Another Navy employee reading this sketch informed the Navy. America Online revealed McVeigh's identity to the Navy, who discharged McVeigh. As the consequence of a court ruling on that case, Timothy McVeigh was allowed to return to the Navy. Sometimes anonymity really matters.

On the Net you still have several possibilities to remain anonymous. You may visit web sites via an anonymizing service. You might use a Web mail account (given the personal information given to the web mail service provider is not true) or you might use an anonymous remailing service which strips off the headers of your mail to make it impossible to identify the sender and forward your message. Used in combination with encryption tools and technologies like FreeHaven or Publius anonymous messaging services provide a powerful tool for countering censorship.

In Germany, in 1515, printers had to swear not to print or distribute any publication bypassing the councilmen. Today repressive regimes, such as China and Burma, and democratic governments, such as the France and Great Britain, alike impose or already have imposed laws against anonymous publishing on the Net.

Anonymity might be used for abuses, that is true, but "the burden of proof rests with those who would seek to limit it. (Rob Kling, Ya-ching Lee, Al Teich, Mark S. Frankel, Assessing Anonymous Communication on the Internet: Policy Deliberations, in: The Information Society, 1999).

Virtual cartels, oligopolistic structures

Global networks require global technical standards ensuring the compatibility of systems. Being able to define such standards makes a corporation extremely powerful. And it requires the suspension of competitive practices. Competition is relegated to the symbolic realm. Diversity and pluralism become the victims of the globalisation of baroque sameness.

The ICT market is dominated by incomplete competition aimed at short-term market domination. In a very short time, new ideas can turn into best-selling technologies. Innovation cycles are extremely short. But today's state-of-the-art products are embryonic trash.

    According to the Computer and Communications Industry Association, Microsoft is trying to aggressively take over the network market. This would mean that AT&T would control 70 % of all long distance phone calls and 60 % of cable connections.



    AOL and Yahoo are lone leaders in the provider market. AOL has 21 million subscribers in 100 countries. In a single month, AOL registers 94 million visits. Two thirds of all US internet users visited Yahoo in December 1999.



    The world's 13 biggest internet providers are all American.



    AOL and Microsoft have concluded a strategic cross-promotion deal. In the US, the AOL icon is installed on every Windows desktop. AOL has also concluded a strategic alliance with Coca Cola.

Eliminating online censorship: Freenet, Free Haven and Publius

Protecting speech on the global data networks attracts an increasing attention. The efforts and the corresponding abilities of governmental authorities, corporations and copyright enforcement agencies are countered by similar efforts and abilities of researchers and engineers to provide means for anonymous and uncensored communication, as Freenet, Free Haven and Publius. All three of them show a similar design. Content is split up and spread on several servers. When a file is requested, the pieces are reassembled. This design makes it difficult to censor content. All of these systems are not commercial products.

The most advanced system seems to be Publius. Because of being designed by researchers and engineers at the prestigious AT&T Labs, Publius is a strong statement against online censorship. No longer can it be said that taking a firm stand against the use of technologies limiting the freedom of individuals is a position of radical leftists only.

For more information on Publius, see John Schwartz, Online and Unidentifiable? in: The Washington Post, June 30, 2000, http://www.washingtonpost.com/wp-dyn/articles/A21689-2000Jun29.html .

Key Recovery Systems

As stated before the sense of cryptography is a properly designed cryptosystem making it essentially impossible to recover encrypted data without any knowledge of the used key. The issue of lost keys and the being-locked-out from one's own data as a consequence favors key recovery systems. On the other hand the counter argument is confidentiality: as soon as a possibility to recover a key is provided, the chances for abuses grow.
Finally it is the state that does not want to provide too much secrecy. On the contrary. During the last 20 years endless discussions about the state's necessity and right to restrict private cryptography have taken place, as the governments rarely care for the benefit of private users if they believe in catching essential informations about any kind of enemy, hence looking for unrestricted access to all keys.

The list of "key recovery," "key escrow," and "trusted third-party" as encryption requirements, suggested by governmental agencies, covers all the latest developments and inventions in digital technology.
At the same time the NSA, one of the world's most advanced and most secret enterprises for cryptography, worked hard in getting laws through to forbid the private use of strong encryption in one way or the other. Still, it is also organizations like this one that have to admit that key recovery systems are not without any weaknesses, as the U.S. Escrowed Encryption Standard, the basis for the famous and controversially discussed Clipper Chip, showed. The reason for those weaknesses is the high complexity of those systems.

Another aspect is that key recovery systems are more expensive and certainly much less secure than other systems. So, why should anyone use them?

In that context, one has to understand the legal framework for the use of cryptography, a strict framework in fact, being in high contradiction to the globalised flow of communication.

Gait recognition

The fact that an individual's identity is expressed not only by the way he/she looks or sounds, but also by the manner of walking is a relatively new discovery of in biometrics.

Unlike the more fully developed biometric technologies whose scrutiny is directed at stationary parts of the body, gait recognition has the added difficulty of having to sample and identify movement. Scientists at the University of Southampton, UK (http://www.isis.ecs.soton.ac.uk/research/gait/) have developed a model which likens the movement of legs to those of a pendulum and uses hip inclination as a variable.

Another model considers the shape and length of legs as well as the velocity of joint movements. The objective is to combine both models into one, which would make gait recognition a fully applicable biometric technology.

Given that gait recognition is applied to "moving preambulatory subjects" it is a particularly interesting technology for surveillance. People can no longer hide their identity by covering themselves or moving. Female shop lifters who pretend pregnancy will be detected because they walk differently than those who are really pregnant. Potential wrongdoers might resort walking techniques as developed in Monty Pythons legendary "Ministry of Silly Walks" (http://www.stone-dead.asn.au/sketches/sillwalk.htm)

DES

The U.S. Data Encryption Standard (= DES) is the most widely used encryption algorithm, especially used for protection of financial transactions. It was developed by IBM in 1971. It is a symmetric-key cryptosystem. The DES algorithm uses a 56-bit encryption key, meaning that there are 72,057,594,037,927,936 possible keys.

Cyrus Reed Teed

C.R. Teed (New York State) was a doctor of alternative medicine in the last century. He worked on alchemy, too. In 1870 he had the idea that the universe was made out of cells, the earth being the biggest one. Thus he imagined the world as a concave system. Out of this thought he founded a religion, calling it Koreshanity.

Proxy Servers

A proxy server is a server that acts as an intermediary between a workstation user and the Internet so that security, administrative control, and caching service can be ensured.

A proxy server receives a request for an Internet service (such as a Web page request) from a user. If it passes filtering requirements, the proxy server, assuming it is also a cache server, looks in its local cache of previously downloaded Web pages. If it finds the page, it returns it to the user without needing to forward the request to the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from the server out on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it on to the user.

Themistocles

Themistocles, a Greek politician and general, conquered the Persians in the battle of Salamis, in 480 BC. The Persians, under their King Xerxes, who were on the edge of winning the battle, got defeated by a propaganda campaign that Themistocles launched, telling the Persians that he was on their side and willing to let them win the battle; his argument was that the Greek were so busy with their quarrels that they were not prepared to fight an aggressive battle and a lot of them would change sides if the power of the Persians was shown in a short and cruel fight. In the end Xerxes got the message that parts of the Greek army were fleeing the battlefield. This disinformation lead to a wrong assessment of Xerxes, which made it easy for the Greek to win the war.
