How the Wayback Machine Works

The Internet Archive is an amazing database of old web sites. James Chartrand pointed me to an interview with the director of the Internet Archive, Brewster Kahle from January 21, 2002, titled How the Wayback Machine Works. The interview is by Richard Koman and still interesting, especially for those of us interested in text spiders and archives. I was intrigued by Kahle’s claim that the IA is the largest database in the world, “It’s larger than Walmart’s, American Express’, the IRS. It’s the largest database ever built.”

Canadian Multimedia: the Cyclorama of Jerusalem

The Cyclorama of Jerusalem is one of the few remaining large panoramas that are still on exhibition. (The other one I know of is at Gettysburg.) Is was created in the 1880s and has been exhibited at the pilgrimage site of Sainte-Anne-de-Beauprè since 1895. Cycloramas are large paintings that form a complete circle creating a “virtual” space where you can immerse yourself in a place and time. As the glossy brochure says, “We claim 3-D as a modern invention but this Cyclorama, in existence for a so long time, gives such an illusion of depth that viewers feel they are among the crowd marching with Roman soldiers…” (p. 2)
My theory is that types of media are like species – you have periods of exploding variety, and then something happens, and all the experiments die out before a particular technology. The late 19th century saw an explosion of different types of immersive media, including panoramas and other optical expositions. Cinema made them all obsolete, effectively wiping the variety out. We are now in another period of expanding diversity – what technology will survive?

Mahoney on the History of Theory in Computer Science

I’m reading an article by Michael S. Mahoney in The First Computers. It is titled “The Structures of Computation” and Mahoney (who is one of the best historians of computing I have read – see my previous entry, History of Computing) makes a closing point,

The history of science has until recently tended to ignore the role of technology in scientific thought, … The situation has begun to change with recent work on the role and nature of the instruments that have mediated between scientists and the objects of their study, … But, outside of the narrow circle of people who think of themselves as historians of computing, historians of science (and indeed of technology) have ignored the instrument that by now so pervades science and technology as to be indispensable to their practice. Increasingly, computers not only mediate between practitioners and their subjects but also replace the subjects with computed models. … Some time soon, historians are going to have to take the computer seriously as an object of study, and it will be important, when they do, that they understand the ambiguous status of the computer itself. (p. 31)

I would go further and say that not only historians, but philosophers, and for that matter other humanities disciplines, are going to have to take seriously the ambiguous nature of the computer as instrument and extension in all knowledge disciplines.

Canadian Early Information Technology: Marconi and Nova Scotia

IMG_5487.JPG.200.jpg
On our trip out East we visited a number of sites associated with the early history of telecommunications. At Glace Bay, Nova Scotia, a depressed and exhausted mining town (with a great mining museum) there is a small Marconi National Historic Site of Canada managed by Parks Canada. It is a one room museum on Table Head, a flat windy site above the ocean. Here, in 1902, Marconi established reliable radio transatlantic radio communication. (He had successfully recieved the first signals at Signal Hill in Newfoundland a year earlier, but was forced to move.) For more see the Parks Canada History page.

System Mimicry

WebSE – System 7.0 – Test Drive a Macintosh… is a site that has a Flash (?) simulation of the Apple Macintosh System 7.0 on an SE. I think we will see more of these as ways of preserving the culture of computing. This project should be expanded to a MAME type project for old operating systems. We build on SWF a simulation engine with which to create interactive simulations of old environments.

(Added on May 27, 2004) Thanks to St?©fan Sinclair, here is another simulation of an old Mac. P.dro Classic emulates not just the screen, but has a mouse that moves on a pad and post-it notes. An interesting idea that isn’t executed completely. I could be wrong, but some parts of the emulation are wrong. It is also marred by an unnecessary folder of low-rez porn. This appears to be more of an exercise in nostalgia than a serious attempt to capture the experience of an early Mac.
