1940s - 1950s: The Development of Early Robotics Technology

During the 1940s and 1950s two major developments enabled the design of modern robots. Robotics generally is based on two related technologies: numerical control and teleoperators.

Numerical control was invented during the late 1940s and early 1950s. It is a method of controlling machine tool axes by means of numbers that have been coded on media. The first numerical control machine was presented in 1952 at the Massachusetts Institute of Technology (MIT), whose subsequent research led to the development of APT (Automatically Programmed Tools). APT, a language for programming machine tools, was designed for use in computer-assisted manufacturing (CAM).

First teleoperators were developed in the early 1940s. Teleoperators are mechanical manipulators which are controlled by a human from a remote location. In its typical application a human moves a mechanical arm and hand with its moves being duplicated at another location.

Timeline BC

~ 1900 BC: Egyptian writers use non-standard Hieroglyphs in inscriptions of a royal tomb; supposedly this is not the first but the first documented example of written cryptography

1500 an enciphered formula for the production of pottery is done in Mesopotamia

parts of the Hebrew writing of Jeremiah's words are written down in "atbash", which is nothing else than a reverse alphabet and one of the first famous methods of enciphering

4th century Aeneas Tacticus invents a form of beacons, by introducing a sort of water-clock

487 the Spartans introduce the so called "skytale" for sending short secret messages to and from the battle field

170 Polybius develops a system to convert letters into numerical characters, an invention called the Polybius Chequerboard.

50-60 Julius Caesar develops an enciphering method, later called the Caesar Cipher, shifting each letter of the alphabet an amount which is fixed before. Like atbash this is a monoalphabetic substitution.

Who owns the Internet and who is in charge?

The Internet/Matrix still depends heavily on public infrastructure and there is no dedicated owner of the whole Internet/Matrix, but the networks it consists of are run and owned by corporations and institutions. Access to the Internet is usually provided by Internet Service Providers (ISPs) for a monthly fee. Each network is owned by someone and has a network operation center from where it is centrally controlled, but the Internet/Matrix is not owned by any single authority and has no network operation center of its own. No legal authority determines how and where networks can be connected together, this is something the managers of networks have to agree about. So there is no way to ever gain ultimate control of the Matrix/Internet.
The in some respects decentralized Matrix/Internet architecture and administration do not imply that there are no authorities for oversight and common standards for sustaining basic operations, for administration: There are authorities for IP number and domain name registrations, e.g.
Ever since the organizational structures for Internet administration have changed according to the needs to be addressed. Up to now, administration of the Internet is a collaborative undertaking of several loose cooperative bodies with no strict hierarchy of authority. These bodies make decisions on common guidelines, as communication protocols, e.g., cooperatively, so that compatibility of software is guaranteed. But they have no binding legal authority, nor can they enforce the standards they have agreed upon, nor are they wholly representative for the community of Internet users. The Internet has no official governing body or organization; most parts are still administered by volunteers.
Amazingly, there seems to be an unspoken and uncodified consent of what is allowed and what is forbidden on the Internet that is widely accepted. Codifications, as the so-called Netiquette, are due to individual efforts and mostly just expressively stating the prevailing consent. Violations of accepted standards are fiercely rejected, as reactions to misbehavior in mailing lists and newsgroups prove daily.
Sometimes violations not already subject to law become part of governmental regulations, as it was the case with spamming, the unsolicited sending of advertising mail messages. But engineers proved to be quicker and developed software against spamming. So, in some respects, the Internet is self-regulating, indeed.

Intranet

As a local area network (LAN), an Intranet is a secured network of computers based on the IP protocol and with restricted access.

Cutting

The cutting of pictures in movies or photographs is highly manipulative: it is easy to produce a new video out of an already existing one. The result is a form of manipulation that is difficult to contradict. A reputation destroyed by this, is nearly impossible to heal.
