1940s - Early 1950s: First Generation Computers

Probably the most important contributor concerning the theoretical basis for the digital computers that were developed in the 1940s was Alan Turing, an English mathematician and logician. In 1936 he created the Turing machine, which was originally conceived as a mathematical tool that could infallibly recognize undecidable propositions. Although he instead proved that there cannot exist any universal method of determination, Turing's machine represented an idealized mathematical model that reduced the logical structure of any computing device to its essentials. His basic scheme of an input/output device, memory, and central processing unit became the basis for all subsequent digital computers.

The onset of the Second World War led to an increased funding for computer projects, which hastened technical progress, as governments sought to develop computers to exploit their potential strategic importance.

By 1941 the German engineer Konrad Zuse had developed a computer, the Z3, to design airplanes and missiles. Two years later the British completed a secret code-breaking computer called Colossus to decode German messages and by 1944 the Harvard engineer Howard H. Aiken had produced an all-electronic calculator, whose purpose was to create ballistic charts for the U.S. Navy.

Also spurred by the war the Electronic Numerical Integrator and Computer (ENIAC), a general-purpose computer, was produced by a partnership between the U.S. government and the University of Pennsylvania (1943). Consisting of 18.000 vacuum tubes, 70.000 resistors and 5 million soldered joints, the computer was such a massive piece of machinery (floor space: 1,000 square feet) that it consumed 160 kilowatts of electrical power, enough energy to dim lights in an entire section of a bigger town.

Concepts in computer design that remained central to computer engineering for the next 40 years were developed by the Hungarian-American mathematician John von Neumann in the mid-1940s. By 1945 he created the Electronic Discrete Variable Automatic Computer (EDVAC) with a memory to hold both a stored program as well as data. The key element of the Neumann architecture was the central processing unit (CPU), which allowed all computer functions to be coordinated through a single source. One of the first commercially available computers to take advantage of the development of the CPU was the UNIVAC I (1951). Both the U.S. Census bureau and General Electric owned UNIVACs (Universal Automatic Computer).

Characteristic for first generation computers was the fact, that instructions were made-to-order for the specific task for which the computer was to be used. Each computer had a different binary-coded program called a machine language that told it how to operate. Therefore computers were difficult to program and limited in versatility and speed. Another feature of early computers was that they used vacuum tubes and magnetic drums for storage.

fingerprint identification

Although fingerprinting smacks of police techniques used long before the dawn of the information age, its digital successor finger scanning is the most widely used biometric technology. It relies on the fact that a fingerprint's uniqueness can be defined by analysing the so-called "minutiae" in somebody's fingerprint. Minutae include sweat pores, distance between ridges, bifurcations, etc. It is estimated that the likelihood of two individuals having the same fingerprint is less than one in a billion.

As an access control device, fingerprint scanning is particularly popular with military institutions, including the Pentagon, and military research facilities. Banks are also among the principal users of this technology, and there are efforts of major credit card companies such as Visa and MasterCard to incorporate this finger print recognition into the bank card environment.

Problems of inaccuracy resulting from oily, soiled or cracked skins, a major impediment in fingerprint technology, have recently been tackled by the development a contactless capturing device (http://www.ddsi-cpc.com) which translates the characteristics of a fingerprint into a digitised image.

As in other biometric technologies, fingerprint recognition is an area where the "criminal justice" market meets the "security market", yet another indication of civilian spheres becomes indistinguishable from the military. The utopia of a prisonless society seems to come within the reach of a technology capable of undermining freedom by an upward spiral driven by identification needs and identification technologies.

Advertising

Advertising as referred to in most economic books is part of the marketing mix. Therefore advertising usually is closely associated with the aim of selling products and services. Still, developments like "branding" show a tendency towards the marketing of not only products and services, but of ideas and values. While advertising activities are also pursued by political parties, politicians and governmental as well as non-governmental organizations, most of the money flowing into the advertising industry comes from corporations. Although these clients come from such diverse fields, their intentions hardly differ. Attempting to influence the public, their main goal is to sell: Products, services, ideas, values and (political) ideology.

Introduction: The Substitution of Human Faculties with Technology: Computers and Robots

With the development of modern computing, starting in the 1940s, the substitution of human abilities with technology obtained a new dimension. The focus shifted from the replacement of pure physical power to the substitution of mental faculties. Following the early 1980s personal computers started to attain widespread use in offices and quickly became indispensable tools for office workers. The development of powerful computers combined with progresses in artificial intelligence research also led to the construction of sophisticated robots, which enabled a further rationalization of manufacturing processes.

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 .

Palm recognition

In palm recognition a 3-dimensional image of the hand is collected and compared to the stored sample. Palm recognition devices are cumbersome artefacts (unlike fingerprint and iris recognition devices) but can absorb perform a great amount of identification acts in a short time. They are therefore preferably installed in situations where a large number of people is identified, as in airports.

Harold. D. Lasswell

Harold. D. Lasswell (* 1902) studied at the London School of Economics. He then became a professor of social sciences at different Universities, like the University of Chicago, Columbia University, and Yale University. He also was a consultant for several governments. One of Lasswell's many famous works was Propaganda Technique in World War. In this he defines propaganda. He also discussed major objectives of propaganda, like to mobilize hatred against the enemy, to preserve the friendship of allies, to procure the co-operation of neutrals and to demoralize the enemy.

Gerard J. Holzmann and Bjoern Pehrson, The Early History of Data Networks

This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network.

Writing

Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets are used for administrative purposes. As an instrument for the administrative bodies of early empires, who began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to a few. Being more or less separated tasks, writing and calculating converge in today's computers.

Letters are invented so that we might be able to converse even with the absent, says Saint Augustine. The invention of writing made it possible to transmit and store information. No longer the ear predominates; face-to-face communication becomes more and more obsolete for administration and bureaucracy. Standardization and centralization become the constituents of high culture and vast empires as Sumer and China.

Cutting

The cutting of pictures in movies or photographs is highly manipulative: it is easy to produce a new video out of an already existing one. The result is a form of manipulation that is difficult to contradict. A reputation destroyed by this, is nearly impossible to heal.
