“History is who we are and why we are the way we are”*…

What a long, strange trip it’s been…

March 12, 1989 Information Management, a Proposal

While working at CERN, Tim Berners-Lee first comes up with the idea for the World Wide Web. To pitch it, he submits a proposal for organizing scientific documents to his employers titled “Information Management, a Proposal.” In this proposal, Berners-Lee sketches out what the web will become, including early versions of the HTTP protocol and HTML.

The first entry a timeline that serves as a table of contents for a series of informative blog posts: “The History of the Web,” from @jay_hoffmann.

As we jack in, we might recall that it was on this date in 1969 that the world first learned of what would become the internet, which would, in turn, become that backbone of the web: UCLA announced it would “become the first station in a nationwide computer network which, for the first time, will link together computers of different makes and using different machine languages into one time-sharing system.” It went on to say that “Creation of the network represents a major forward step in computer technology and may server as the forerunner of large computer networks of the future.”

UCLA will become the first station in a nationwide computer network which, for the first time, will link together computers of different makes and using different machine languages into one time-sharing system.

Creation of the network represents a major forward step in computer technology and may serve as the forerunner of large computer networks of the future.

The ambitious project is supported by the Defense Department’s Advanced Research Project Agency (ARPA), which has pioneered many advances in computer research, technology and applications during the past decade. The network project was proposed and is headed by ARPA’s Dr. Lawrence G. Roberts.

The system will, in effect, pool the computer power, programs and specialized know-how of about 15 computer research centers, stretching from UCLA to M.I.T. Other California network stations (or nodes) will be located at the Rand Corp. and System Development Corp., both of Santa Monica; the Santa Barbara and Berkeley campuses of the University of California; Stanford University and the Stanford Research Institute.

The first stage of the network will go into operation this fall as a subnet joining UCLA, Stanford Research Institute, UC Santa Barbara, and the University of Utah. The entire network is expected to be operational in late 1970.

Engineering professor Leonard Kleinrock [see here], who heads the UCLA project, describes how the network might handle a sample problem:

Programmers at Computer A have a blurred photo which they want to bring into focus. Their program transmits the photo to Computer B, which specializes in computer graphics, and instructs B’s program to remove the blur and enhance the contrast. If B requires specialized computational assistance, it may call on Computer C for help.

The processed work is shuttled back and forth until B is satisfied with the photo, and then sends it back to Computer A. The messages, ranging across the country, can flash between computers in a matter of seconds, Dr. Kleinrock says.

UCLA’s part of the project will involve about 20 people, including some 15 graduate students. The group will play a key role as the official network measurement center, analyzing computer interaction and network behavior, comparing performance against anticipated results, and keeping a continuous check on the network’s effectiveness. For this job, UCLA will use a highly specialized computer, the Sigma 7, developed by Scientific Data Systems of Los Angeles.

Each computer in the network will be equipped with its own interface message processor (IMP) which will double as a sort of translator among the Babel of computer languages and as a message handler and router.

Computer networks are not an entirely new concept, notes Dr. Kleinrock. The SAGE radar defense system of the Fifties was one of the first, followed by the airlines’ SABRE reservation system. At the present time, the nation’s electronically switched telephone system is the world’s largest computer network.

However, all three are highly specialized and single-purpose systems, in contrast to the planned ARPA system which will link a wide assortment of different computers for a wide range of unclassified research functions.

“As of now, computer networks are still in their infancy,” says Dr. Kleinrock. “But as they grow up and become more sophisticated, we will probably see the spread of ‘computer utilities’, which, like present electronic and telephone utilities, will service individual homes and offices across the country.”

A Symbolic Achievement…

source: PaperBlog

Like the ampersand, the “@” symbol is not strictly a mark of punctuation; rather, it is a logogram or grammalogue, a shorthand for the word “at.”  Even so, it is as much a staple of modern communication as the semicolon or exclamation mark, punctuating email addresses and announcing Twitter usernames. Unlike the ampersand, though, whose journey to the top took two millennia of steady perseverance, the at symbol’s current fame is quite accidental. It can, in fact, be traced to the single stroke of a key made almost exactly four decades ago*

The whole story is @ Shady Characters (“The Secret Life of Punctuation”).

* Before it became the domain address marker– and the overall symbol– for email, “@” was used to denote the unit price (or weight) of an item:  10 books @ $1.00 would total $10.00…  the symbol is believed to have originated with medieval scribes who used the symbol to eliminate the two extra pen strokes that would have been necessary to write “at.”

As we check our spam filters, we might recall that it was on this date in 1958, in reaction to the Soviet’s Sputnik success the prior year, that Congress passed the legislation establishing the National Aeronautics and Space Administration (NASA)… the Space Race was on.  (ARPA [now DARPA]– the sponsor of the work that spawned the internet and birthed the “@” in the form in which we all now use it– was born the same year out of the same concern over Soviet scientific progress.)

Explanations one would really rather not have to give…

EATR (source)

From a press release issued by Cyclone Power Technologies and Robotic Technology:

In response to rumors circulating the internet on sites such as FoxNews.com, FastCompany.com and CNET News about a “flesh eating” robot project [ c.f., e.g., EATR: The Robot That Can Survive on Corpses], Cyclone Power Technologies Inc. (Pink Sheets: CYPW) and Robotic Technology Inc. (RTI) would like to set the record straight: This robot is strictly vegetarian.

On July 7, Cyclone announced that it had completed the first stage of development for a beta biomass engine system used to power RTI’s Energetically Autonomous Tactical Robot (EATR™), a Phase II SBIR project sponsored by the Defense Advanced Research Projects Agency (DARPA), Defense Sciences Office. RTI’s EATR is an autonomous robotic platform able to perform long-range, long-endurance missions without the need for manual or conventional re-fueling.

RTI’s patent pending robotic system will be able to find, ingest and extract energy from biomass in the environment. Despite the far-reaching reports that this includes “human bodies,” the public can be assured that the engine Cyclone has developed to power the EATR runs on fuel no scarier than twigs, grass clippings and wood chips – small, plant-based items for which RTI’s robotic technology is designed to forage. Desecration of the dead is a war crime under Article 15 of the Geneva Conventions, and is certainly not something sanctioned by DARPA, Cyclone or RTI.

“We completely understand the public’s concern about futuristic robots feeding on the human population, but that is not our mission,” stated Harry Schoell, Cyclone’s CEO. “We are focused on demonstrating that our engines can create usable, green power from plentiful, renewable plant matter. The commercial applications alone for this earth-friendly energy solution are enormous.”

As we contemplate off-label uses, we might also celebrate the happier fall-out of military maneuvers, as it was on this date in 1799 (or close; scholars agree that it was “mid-July” but disagree on the precise day) that a French soldier in Napoleon’s Egyptian Campaign discovered a black basalt slab inscribed with ancient writing near the town of Rosetta, about 35 miles north of Alexandria.

The stone contained fragments of passages written in three different scripts inscribed by priests of Ptolemy V in the second century B.C.– Greek, Egyptian hieroglyphics, and Egyptian demotic.  The Greek passage proclaimed that the three scripts were all of identical meaning– so allowed French Egyptologist Jean Francois Champollion to decipher the hieroglyphics… and opened the language of ancient Egypt, a written language that had been “dead” for nearly two millennia.
