Colussus (aka Panopticon): This class reviews the history of twentieth-century computing to define the mainframe paradigm that dominated from the 1950's through 1970's, and so prepares us to understand the transition to the subsequent network paradigm. Teaser question: why was the Post-It note such a successful invention at the height of the mainframe age?
A Short History of Information Technology in the 20th Century (includes some material from Alan Liu, The Laws of Cool: The Cultural Life of Information, work-in-progress under contract with Stanford Univ. Press)
Our organizing topic in understanding the mainframe age is the successor to both the paradigms of communicating and mediating: "interfacing" (which will eventually also incorporate "personal computing" and "networking"). Our general questions will be: what was the experience of the interface in the age of the mainframe computer? How does that experience change in the personal computer/network age? And how does contemporary "interface culture" (as Steven Johnson terms it) not only recapitulate communicating and mediating but extend these acts of information in new directions? |

Instructor's Preliminary Questions Is Heidegger right about the modernity of the "world picture"? What about the early
modern period? (a,
b, c,
d) The World Picture does not seem to have anything to do with communication (it's a very lonely world that Heidegger paints). Is the World Picture the same as "media," however? Is there a "back stage" to the World Picture? Whatever does Heidegger mean by the "incalculable"? The World Picture is a representation of the world to vision. What is "reflection" as Heidegger uses the term in his discussion of the incalculable, and how is reflection related to vision? Is GIS as exampled by Borgmann an example of Heidegger's World Picture? (Cf., medical imaging) What is the relation between Borgmann's "transparency" and Heidegger's "reflection"? Compare also Zuboff's "reflection." So, what does information "look" like? |

Technological Information: A Definition From the Point of View of Literacy Technological information could simply be defined as the object of information technology. But we can be more explicit and define it structurally as the information that is measured in bits, ordered by Boolean algebra, and conveyed by electrons. It has a plausible claim to representing the fundamental and universal alphabet and grammar of information. (p. 166) Technological Information: A Definition From the Point of View of Machinery [ . . . ] digital rigor, the massive logic and
data structures, and the rapid processing of technological information.
Technological Information: A Definition From the Point of View of Visualization The genius of information technology consists in making information pliable by digitizing it, making it abundantly available by collecting and storing astronomical amounts of it, and putting it at our disposal through powerful processing and display devices. (pp. 170-71) Eye-Max Theater: Information as Omni-Vision Technological information can reveal otherwise invisible things not
only on and above the earth, but beneath the earth as well. The very
rock and soil of a stretch of north-central Montana has been made transparent
by a computer model of the geology under the Rabbit Hills oil field.
The model represents an "integration of 3-dimensional seismic data,
geologic and engineering models that accommodate variations of physical
scale and relative emphasis of data, and finally a visualization of
the integrated model set" (see
fig. 18). The model consists of six or so colored and layered surfaces
that represent the strata of this area, and it allows you to fly through
this layered space to reach different viewpoints and perspectives on
where, for example, the shafts of the oil wells penetrate and terminate
in the layers of sand and rock. [Cf., DOE
Petroleum Reservoir Characterization Project, Geological
Images from U. Montana Computer Science Dept.] Transparency of information would approach perfection if all information about reality could be united in one well-ordered information space, realizing electronically the Memory Theater that Giulio Camillo conceived in the sixteenth century. His idea was to order all knowledge in a carefully arranged fan shape. "He pretends," a contemporary observer noted, "that all things that the human mind can conceive and which we cannot see with the corporeal eye, after being collected together by diligent meditation may be expressed by certain corporeal signs in such a way that the beholder may at once perceive with his eyes everything that is otherwise hidden in the depths of the human mind. And it is because of this corporeal looking that he calls it a theatre." Today's prototype of such a space, the Internet (or, more vaguely, cyberspace) is far from all inclusive and well structured. But Camillo's encyclopedic ambition survives in today's notions of spatial navigation, hyperlinking, and search engines." (p. 175) To this hierarchy of boxes, extending from the transistor to the computer, there roughly corresponds a hierarchy of languages. The one that uses the vocabulary of bits and the grammar of Boolean algebra is closest to the physical structure of the machine and is called machine language. Pieces and processes of the machine language are gathered into the terms and operations of the assembly language whereon is layered the compiler language, the programming language, and so on. just as for the common user the physical structures of the computer have coalesced and become opaque in a box, so the languages of the computer have congealed into the lingua franca of point and click. (pp. 167-68) Transparency, however, is anything but transparent and casts its own shadows of enigma and confusion. Edward Tufte, who has worked hard to promote high standards for the graphic visualization of information, concludes that principles of good design "are not logically or mathematically certain" and that most of them "should be greeted with some skepticism." (p. 175) This dimming of transparency occurs at the operational level of technological information where scientists use high-level computer languages, computer graphics, and software packages. But even where clarity reigns at this stratum, it rests on a substratum of machinery that is becoming concealed from the understanding of those who operate on its surface." The blackboxing that is the consequence of progress in information technology encloses ever larger spaces of hardware and software. It is an unavoidable development. (p. 176) Transparency as a norm of clarity and presentation, however, has no
intrinsic points of rest or satisfaction. On a bad day in winter the
air in the Missoula valley is anything but transparent and dims the
outlines of the hills and mountains. Air pollution impairs visibility.
But the level and extent of pollution are themselves unclear until you
climb one of the nearby mountains and see bow the brownish smog fills
the valley and is lapping up the hillsides as Lake Missoula did in the
last ice age. Thus from high above something can present itself clearly
that from the valley bottom is an obstacle to clarity. |
