some essential definitions some essential definitions in the field of cryptography are: - - - "Few false ideas have more firmly gripped the minds of so many intelligent men than the one that, if they just tried, they could invent a cipher that no one could break." (David Kahn) The variants of encryption systems are endless. For deciphering there exists always the same game of trial and error (first guessing the encryption method, then the code). A help to do so is pruning. Once, after a more or less long or short period a code/cipher breaks. Monoalphabetic ciphers can be broken easily and of course are no longer used today but for games. for further information on codes and ciphers etc. see: |

1970s: Computer-Integrated Manufacturing (CIM) Since the 1970s there had been a growing trend towards the use of computer programs in manufacturing companies. Especially functions related to design and production, but also business functions should be facilitated through the use of computers. Accordingly the CAD/CAM technology, related to the use of computer systems for design and production, was developed. CAD (computer-aided design) was created to assist in the creation, modification, analysis, and optimization of design. CAM (computer-aided manufacturing) was designed to help with the planning, control, and management of production operations. CAD/CAM technology, since the 1970s, has been applied in many industries, including machined components, electronics products, equipment design and fabrication for chemical processing. To enable a more comprehensive use of computers in firms the |

Advertising and the Content Industry - The Coca-Cola Case Attempts to dictate their rules to the media has become a common practice among marketers and the advertising industry. Similar as in the According to a memo published by the New York Post, Coca-Cola demands a free ad from any publication that publishes a Coke ad adjacent to stories on religion, politics, disease, sex, food, drugs, environmental issues, health, or stories that employ vulgar language. "Inappropriate editorial matter" will result in the publisher being liable for a "full make good," said the memo by Coke advertising agency (Source: Odwyerpr.com: Coke Dictates nearby Editorial. |

biotechnology introduction One of the most critical trends in the western culture what might be called the "fusion of flesh and machine". Increasingly, technological artifacts such as computers, rather than being used as tools by people, are functioning as parts of the human organism. On the other hand, human functionalities such as intelligence, emotion, adaptability or reproductivity are integrated into technological artifacts: the days when computers where only able to count apples and pears and their intelligence was not even matching an insect's are rapidly becoming history. Today, the boundaries between organisms and technology are losing their significance. As new technologies are no longer mere instruments, or "extensions" of the organism, they acquire the capability of modifying the human organism - body and mind - from within according to certain pre-established principles. The history of the evolution of the human species is hastily being re-written as artificial beings begin to mock the categories of evolution and seem to work their way towards historical subjectivity. The German philosopher Günther Anders has extensively reflected on the changes of the human condition provoked by the development of modern technology speaks of an "antiquatedness of history" at a time when technology itself becomes a historical subject and men are becoming co-historical. However, the softening of the biological definition of the human race is a theme which has accompanied western thinking ever since its origins. Beings half man-half animal crowd the tales of classical mythology and transcend the boundary between the human from below, while divine creatures, temporarily occupying humanoid bodies, relativise humanness form "above". What exactly "being human" meant and who "human beings" could be "defined" is a question with a long history. "Der Mensch ist das nicht festgestellte Thier" as Nietzsche commented. Just as the boundaries between human and non-human are being crossed by technological development, so also the boundaries between the classical episteme are becoming permeable. Psychology is occupying itself with the emotions of machines, while physics and cybernetics is applied to the human mind and body. The "nicht festgestellte "character of humanness has meant that imagination has become just as relevant a factor in understanding humanness as science. Science fiction as a literary genre is no longer merely a depository of phantasies about a technisised world our of control. As the human monopoly on history seems to dissolve, the baroque narratives of science fiction have also become a resource for understanding history. However, it is evident that the potentials of the new technologies gives rise not only to wild hopes and dreams and to bizarre stories; they also harbour some real ambiguities of a political and ethical nature. Not only does the merging of previously distinct realities - the human and the non-human worlds - unhinge theories and institutions based upon a clear distinction and separation of the two, it also is placing political practice on a different footing. Will artificial life have rights? Will artificial entities have political power? How will social relationships change? |

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 |

Blaise Pascal b. June 19, 1623, Clermont-Ferrand, France d. August 19, 1662, Paris, France French mathematician, physicist, religious philosopher, and master of prose. He laid the foundation for the modern theory of probabilities, formulated what came to be known as Pascal's law of pressure, and propagated a religious doctrine that taught the experience of God through the heart rather than through reason. The establishment of his principle of intuitionism had an impact on such later philosophers as Jean-Jacques Rousseau and Henri Bergson and also on the Existentialists. |

Günther Anders Born in Germany in 1913, Günther Anders spent the Nazi period exiled in the USA where he stayed until 1950. His chief work Die Antiquiertheit des Menschen is an extensive analysis of human existence in a technised world. Among the most outstanding theses of Anders is the concept a permanent gap between the potential of technical artefacts and the human mind's power to imagine the consequences of technology. Men think of themselves as "antiquated" in comparison to their artefacts, and feel "promethean embarrassment". Anders was among the first thinkers to react to the Holocaust and the dropping of the Atomic bomb. The ethical quandaries resulting from the latter are documented in an exchange of letters between Anders and Claude Eatherly, the pilot of the Hiroshima plane, in Burning Conscience. |
