some essential definitions

some essential definitions in the field of cryptography are:
- cryptoanalysis
- cryptology
- ciphers

"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)

codes
plaintext
ciphertext
to encipher/encode
to decipher/decode

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.

Product Placement

With television still being very popular, commercial entertainment has transferred the concept of soap operas onto the Web. The first of this new species of "Cybersoaps" was "The Spot", a story about the ups and downs of an American commune. The Spot not only within short time attracted a large audience, but also pioneered in the field of online product placement. Besides Sony banners, the companies logo is also placed on nearly every electronic product appearing in the story. Appearing as a site for light entertainment, The Spots main goal is to make the name Sony and its product range well known within the target audience.

Cyborg

The word "cyborg" short form for "cybernetic organism", i.e. an entity which is partly biological and partly technical. As the technical seizure of nature progresses, cyborgs are proliferating and pose novel theoretical and social questions. The incorporation of technical components into human bodies is not new, but the bio-chips and nano-computers made possible by advances in information technology give a new quality to the development. Because the technization of the body has its origin in military history, cyborg studies have been connected to a critique of militarism, as in Chris Hables Gray, and to feminist critiques of society, as in Donna Haraway.
