The 19th Century: Machine-Assisted Manufacturing Eli Whitney's proposal for a simplification and standardization of component parts marked a further milestone in the advance of the automation of work processes. In 1797 he suggested the manufacture of muskets with completely interchangeable parts. As opposed to the older method under which each gun was the individual product of a highly skilled gunsmith and each part hand-fitted, his method permitted large production runs of parts that were readily fitted to other parts without adjustment and could relatively easy be performed by machines. By the middle of the 19th century the general concepts of division of labor, assembly of standardized parts and machine-assisted manufacture were well established. On both sides of the Atlantic large factories were in operation, which used specialized machines to improve costs, quality and quantity of their products.

Actual Findings on Internet Advertising Although Web advertising becomes a significant portion of marketing budgets, advertisers are still unsure on how to unlock the potential of the Internet. Current findings show that: - Consumer brands spend only a fraction of their advertising budget on on-line advertising. - Technology companies spend five times more on advertising in the WWW. - While banner campaigns are still popular, there is no standardized solution for on-line advertising. - Ad pricing is based on CPM (costs per 1.000 visitors), rather than on results. - Personalized targeting has not yet taken hold. Instead advertisers mainly target on content. At the moment three dominant models are used for Internet advertising: Destination Sites: They use entertainment, high production values and information to pull users in and bring them back again. Micro Sites: Content sites or networks host small clusters of brand pages. Banner Campaigns: Those include other forms of Web advertising like sponsorships.

atbash Atbash is regarded as the simplest way of encryption. It is nothing else than a reverse-alphabet. a=z, b= y, c=x and so on. Many different nations used it in the early times of writing. for further explanations see: http://www.ftech.net/~monark/crypto/crypt/atbash.htm http://www.ftech.net/~monark/crypto/crypt/atb...
