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 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, 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". |

On-line Advertising and the Internet Content Industry Applied to on-line content the advertising model leads to similar problems like in the traditional media. Dependence on advertising revenue puts pressure on content providers to consider advertising interests. Nevertheless new difficulties caused by the technical structure of online media, missing legal regulation and not yet established ethical rules, appear. |

4000 - 1000 B.C. 4th millennium B.C. In Sumer Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets were used for administrative purposes. As an instrument for the administrative bodies of early empires, which began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to only very 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. 3200 B.C. In Sumer the seal is invented. About 3000 B.C. In Egypt papyrus scrolls and About 1350 B.C. In Assyria the cuneiform script is invented. 1200 B.C. According to Aeschylus, the conquest of the town of Troy was transmitted via torch signals. About 1100 B.C. Egyptians use homing pigeons to deliver military information. |

Steganography Ciphers as well as codes are transmitted openly. Everyone can see that they exist. Not so with steganograms. Steganography is the art and science of communicating in a way which hides the existence of the secret part in that communication. During the Italian Renaissance and the time of the Elizabethan Age in England cryptography was very popular, for political reasons as well as for amusements (see John Dee). In literature steganography played an important role. Many steganographs of that period have only been deciphered recently like some of the Shakespearean sonnets, which now seem to proof that the actor William Shakespeare was not the author of the famous poems and dramas, but that the latter' name was, and Francis Bacon, or even Francis Tudor, as some ciphers and other sources talk of him as Queen Elisabeth I.'s secret son. for further details see: One kind of steganogram is digital watermarking: Watermarks protect digital images, videos, but also audio and multimedia products. They are made out of digital signals, put into other digital signals. They try to be invisible on first sight and should be nearly impossible to remove. The process of producing watermarks is to overlay some sort of identifying image over the original image (non-digital watermarks, like on money can be seen by holding the paper against light). Copying the image destroys the watermark, which cannot be copied. Any alteration of the original destroys the watermark, too. Watermarking is one of the typical inventions of cryptography to assist the biggest content owners, but advertised as something necessary and helpful for everybody. Who in fact gets any advantage out of watermarking? The private user most of the time will not really need it except for small entities of pictures maybe. But the big enterprises do. There is a tendency to watermark more and more information in the Internet, which until now was considered as free and as a cheap method to receive information. Watermarking could stop this democratic development. for further information see: |
