Acessing the Internet The Net connections can be based on wire-line and wireless access technolgies.
Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables Satellite communication Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks. Privatization of satellite communication Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as Scheduled privatization of intergovernmental satellite consortia:
When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers. As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost. Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

In Search of Reliable Internet Measurement Data Newspapers and magazines frequently report growth rates of Internet usage, number of users, hosts, and domains that seem to be beyond all expectations. Growth rates are expected to accelerate exponentially. However, Internet measurement data are anything thant reliable and often quite fantastic constructs, that are nevertheless jumped upon by many media and decision makers because the technical difficulties in measuring Internet growth or usage are make reliable measurement techniques impossible. Equally, predictions that the Internet is about to collapse lack any foundation whatsoever. The researchers at the Size and Growth In fact, "today's Internet industry lacks any ability to evaluate trends, identity performance problems beyond the boundary of a single ISP (Internet service provider, M. S.), or prepare systematically for the growing expectations of its users. Historic or current data about traffic on the Internet infrastructure, maps depicting ... there is plenty of measurement occurring, albeit of questionable quality", says K. C. Claffy in his paper Internet measurement and data analysis: topology, workload, performance and routing statistics (http://www.caida.org/Papers/Nae/, Dec 6, 1999). Claffy is not an average researcher; he founded the well-known So his statement is a slap in the face of all market researchers stating otherwise. In a certain sense this is ridiculous, because since the inception of the So what are the reasons for this inability to evaluate trends, identity performance problems beyond the boundary of a single ISP? First, in early 1995, almost simultaneously with the worldwide introduction of the "There are many estimates of the size and growth rate of the Internet that are either implausible, or inconsistent, or even clearly wrong", K. G. Coffman and Andrew, both members of different departments of What is measured and what methods are used? Many studies are devoted to the number of users; others look at the number of computers connected to the Internet or count You get the clue of their focus when you bear in mind that the Internet is just one of many networks of networks; it is only a part of the universe of computer networks. Additionally, the Internet has public (unrestricted) and private (restricted) areas. Most studies consider only the public Internet, Coffman and Odlyzko consider the long-distance private line networks too: the corporate networks, the Hosts The Despite the small sample, this method has at least one flaw: Internet Weather Like daily weather, traffic on the Internet, the conditions for data flows, are monitored too, hence called Internet weather. One of the most famous Internet Hits, Page Views, Visits, and Users Let us take a look at how these hot lists of most visited Web sites may be compiled. I say, may be, because the methods used for data retrieval are mostly not fully disclosed. For some years it was seemingly common sense to report requested files from a Web site, so called "hits". A method not very useful, because a document can consist of several files: graphics, text, etc. Just compile a document from some text and some twenty flashy graphical files, put it on the Web and you get twenty-one hits per visit; the more graphics you add, the more hits and traffic (not automatically to your Web site) you generate. In the meantime page views, also called page impressions are preferred, which are said to avoid these flaws. But even page views are not reliable. Users might share computers and corresponding Especially the editors of some electronic journals (e-journals) rely on page views as a kind of ratings or circulation measure, Rick Marin reports in the More advanced, but just slightly better at best, is counting visits, the access of several pages of a Web site during one session. The problems already mentioned apply here too. To avoid them, newspapers, e.g., establish registration services, which require password authentication and therefore prove to be a kind of access obstacle. But there is a different reason for these services. For content providers users are virtual users, not unique persons, because, as already mentioned, computers and For If you like to play around with Internet statistics instead, you can use Robert Orenstein's Measuring the Density of Measuring the Density of Dodge and Shiode used data on the ownership of IP addresses from | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The Concept of the Public Sphere According to social critic and philosopher The system of the public sphere is extremely complex, consisting of spatial and communicational publics of different sizes, which can overlap, exclude and cover, but also mutually influence each other. Public sphere is not something that just happens, but also produced through social norms and rules, and channeled via the construction of spaces and the media. In the ideal situation the public sphere is transparent and accessible for all citizens, issues and opinions. For democratic societies the public sphere constitutes an extremely important element within the process of public opinion formation. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Virtual cartels, introduction Among the most striking development of the 1990s has been the emergence of a global commercial media market utilizing new technologies and the global trend toward deregulation. This global commercial media market is a result of aggressive maneuvering by the dominant firms, new technologies that make global systems cost-efficient, and neoliberal economic policies encouraged by the World Bank, IMF, WTO, and the US government to break down regulatory barriers to a global commercial media and telecommunication market. A global oligopolistic market that covers the spectrum of media is now crystallizing the very high barriers to entry." (Robert McChesney, author of "Rich Media, Poor Democracy") The network structure of information and communication technologies means that even deregulated markets are not "free". The functional logic of global networks only tolerates a small number of large players. Mergers, strategic alliances, partnerships and cooperations are therefore the daily routine of the ICT business. They bypass competition and create "virtual cartels". | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The third industiral revolution. Life as a product. Many years ago, the German philosopher The "third industrial revolution" is characterized by men becoming the "raw material" of their own industries. Product and producer, production and consumption, technology and nature are no longer meaningful pairs of opposites. The third is also the last revolution, as it is difficult to think of further revolutions when the distinction between subject and object becomes blurred. The world is becoming a Bestand and the human body and mind are no protected zones. They are something like the last safety zone of human being which is now itself becoming a basis for technological innovation. When the subject is weakened by its technical environment, the use of technical crooks for body and mind becomes an obvious "solution", even if the technically strengthened subject is strengthened at the cost of no longer being a "subject" in the traditional, metaphysical sense. Biological processes are dissected and subjected to technical control. This technical control is technical in two senses: it is not only control through technology but by ttechnology itsself, since it is not carried out by unaided human minds, but increasingly by intelligent machines. The point where this Andersian third industrial revolution reaches an unprecedented logic seems to lie within the realm of genetic engeneering. This example shows that the dissection of humanness - the decoding of genetic information - is tantamount to commodification. The purpose of the commercial genetic research projects is the use of genetic information as a resource for the development of new products, e.g. in pharmaceutics. Genetic products carry the promise of offering a solution to so-far uncurable diseases such as cancer, Alzeheimer, heart disorders, schizophrenia, and others, but they also open up the possibility of "breaking the chains of evolution", of actively manipulating the genetic structure of human beings and of "designing" healthy, long-living, beautiful, hard-working etc. beings. Here, the homo creator and the homo materia finally become indistinguishable and we are being to merge with our products in such a way that it "we" loses the remains of its meaning. Since 1990 research on human genetics is organised in the But exactly this patentising is of paramount importance in the emerging "post-industrial" society where knowledge becomes the most important resource. A patent is nothing else than a property title to a piece of "know-how", and an necessary consequence commodification. When life no longer simply a natural creation but a product, it, too, will be patented and becomes a commodity. Against the idea of the human genome as a public good, or an "open source", there is a growing competion on the part of private industry. Companies such as But the commodification of life is not limited ot the human species. Genetically altered animals and plants are also suffering the same fate, and in most industrialised nations it is now possible to patent genetically engeneered species and crops. The promises of the "Green Revolution" of the 1960s are now repeated in the genetic revolution. Genetic engeneering, so it is argued, will be able to breed animals and plants which resist disease and yield more "food" and will therfore help to tackle problems of undernutrition and starvation.

Virtual cartels; mergers In parallel to the deregulation of markets, there has been a trend towards large-scale mergers which ridicules dreams of increased competition. Recent mega-mergers and acquisitions include SBC Communications - Ameritech, $ 72,3 bn Bell Atlantic - GTE, $ 71,3 AT&T - Media One, $ 63,1 AOL - Time Warner, $ 165 bn MCI Worldcom - Spring, $ 129 bn The total value of all major mergers since the beginnings of the 1990s has been 20 trillion Dollars, 2,5 times the size of the USA's GIP. The AOL- Time Warner reflects a trend which can be observed everywhere: the convergence of the ICT and the content industries. This represents the ultimate advance in complete market domination, and a alarming threat to independent content. "Is TIME going to write something negative about AOL? Will AOL be able to offer anything other than CNN sources? Is the Net becoming as silly and unbearable as television?"

Cryptography's Terms and background "All nature is merely a cipher and a secret writing." Blaise de Vigenère In the (dis-)information age getting information but at the same time excluding others from it is part of a power-game (keeping the other uneducated). The reason for it eventually has found an argument called security. Compared to the frequency of its presence in articles, the news and political speeches security seems to be one of the most popular words of the 90's. It must be a long time ago when that word was only used for and by the military and the police. Today one can find it as part of every political issue. Even development assistance and nutrition programs consider it part of its work. The so-called but also real need for information security is widespread and concerning everybody, whether someone uses information technology or not. In any case information about individuals is moving globally; mostly sensitive information like about bank records, insurance and medical data, credit card transactions, and much much more. Any kind of personal or business communication, including telephone conversations, fax messages, and of course e-mail is concerned. Not to forget further financial transactions and business information. Almost every aspect of modern life is affected. We want to communicate with everybody - but do not want anybody to know. Whereas the market already depends on the electronic flow of information and the digital tools get faster and more sophisticated all the time, the rise of privacy and security concerns have to be stated as well. With the increase of digital communication its vulnerability is increasing just as fast. And there exist two (or three) elements competing and giving the term digital security a rather drastic bitter taste: this is on the one hand the growing possibility for criminals to use modern technology not only to hide their source and work secretly but also to manipulate financial and other transfers. On the other hand there are the governments of many states telling the population that they need access to any kind of data to keep control against those criminals. And finally there are those people, living between enlightening security gaps and at the same time harming other private people's actions with their work: computer hackers. While the potential of global information is regarded as endless, it is those elements that reduce it. There is no definite solution, but at least some tools have been developed to improve the situation: cryptography, the freedom to encode those data that one does not want to be known by everybody, and give a possibility to decode them to those who shall know the data. During the last 80 years cryptography has changed from a mere political into a private, economic but still political tool: at the same time it was necessary to improve the tools, eventually based on mathematics. Hence generally cryptography is regarded as something very complicated. And in many ways this is true as the modern ways of enciphering are all about mathematics. "Crypto is not mathematics, but crypto can be highly mathematical, crypto can use mathematics, but good crypto can be done without a great reliance on complex mathematics." (W.T. Shaw) For an introduction into cryptography and the mathematical tasks see: | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Galileo Galilee Galileo Galilee (1564-1642), the Italian Mathematician and Physicist is called the father of Enlightenment. He proofed the laws of the free fall, improved the technique for the telescope and so on. Galilee is still famous for his fights against the Catholic Church. He published his writings in Italian instead of writing in Latin. Like this, everybody could understand him, which made him popular. As he did not stop talking about the world as a ball (the Heliocentric World System) instead of a disk, the Inquisition put him on trial twice and forbid him to go on working on his experiments. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The European Convention on Human Rights and its Five Protocols As can be read in the Convention's preamble, the member states of the Council of Europe, the European Convention on Human Rights is intended as a follow-up of the Universal Declaration of Human Rights proclaimed by the General Assembly of the United Nations on 10 December 1948 and as an official act of "securing the universal and effective recognition and observance of the Rights therein declared." Because it is stated "that the aim of the Council of Europe is the achievement of greater unity between its Members and that one of the methods by which the aim is to be pursued is the maintenance and further realization of Human Rights and Fundamental Freedoms", the European Convention on Human Rights can be read as the political sibling to the biblical Ten Commandments on which effective and legitimate European democratic government are based. The European Convention on Human Rights is intended to represent the essence of the common heritage of European political traditions and ideals. Signed in Rome on November 4, 1950, the Convention is supplemented by five protocols dated from March 20, 1952 (Paris), May 6, 1963, September 16, 1963, and January 20, 1966 (Strasbourg). http://www.hri.org/docs/ECHR50.html | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

First Amendment Handbook The First Amendment to the US Constitution, though short, lists a number of rights. Only a handful of words refer to freedoms of speech and the press, but those words are of incalculable significance. To understand the current subtleties and controversies surrounding this right, check out this First Amendment site. This detailed handbook of legal information, mostly intended for journalists, should be of interest to anyone who reads or writes. For example, the chapter Invasion of Privacy shows the limits of First Amendment rights, and the balance between the rights of the individual and the rights of the public - or, more crudely, the balance of Tabloid vs. Celebrity.
