People are stirring. T...

People are stirring. The session must be almost over. With any luck you'll beat the crowds to the coffee and muffin bar. You reach towards your right front hip, slide your thumb under the gold chain, pull up and slip the watch from its pocket. Cupped in the palm of your hand it reads a quarter 'til... "Cut!... No, no, no!..." "Everyone wears a wristwatch these days!" Sure enough, they do. But why do they still sew that pocket onto their jeans? For decoration, I suppose. But what about that one large button? It has the look of a rivet, but look more closely. The rivet's head is covered by a thin metal cap. It hides the real rivet underneath, but in its place it presents instead the embossed image of a rivet head splayed through the center of a metal washer emblazoned with the Levi-Strauss logo.

The marketplace is full of such things. Hard plastic castings complete with screw heads and unnecessary parts. Soft plastic with molded-in textures of warp and woof and even stitching. Metered postage showing the bold anachronistic elements of the circular town mark and wavy cancellation. Copper cladding over zinc pennies. Steel cladding over copper quarters. All are efforts to make the new look comfortably old and familiar, or simply habits too deeply engrained to wash away.

Archaeologists, who make an academic practice of studying material culture change, while not the first to notice that yesterday's functional features become today's stylistic decorations, were at least the first to name the phenomenon:

Skeuomorph - An ornament or ornamental design due to structure... 1889: "The transfer of thong-work from the flint axe, where it was functional, to the bronze celt, where it was skeuomorphic." [1]

Skeuomorphs are material metaphors. They are informational attributes of artifacts which help us find a path through unfamiliar territory. They help us map the new onto an existing cognitive structure, and in so doing, give us a starting point from which we may evolve additional alternative solutions. They provide us with "a path" instead of "no path" at all, but as scientists we are ultimately interested in an optimal paths well suited to the problem at hand, if not simply the best solution possible. How many of the metaphors we use in evolutionary computing become skeuomorphic downloaded into our machines?

Read only memory

Another place where memory storage was needed was for entertainment purposes: the cylinders and punched disks that operate music boxes, and also the punched paper rolls in player pianos. There was an almost infinite variety of these devices, including some automata programmed by large wooden cylinders with metal pins. I’ve collected some things along these lines but I’ve been more interested in devices directly associated with computing. One very interesting technology that I found recently is cam memory. One example that I really like contains information on how to adjust from the local compass reading anywhere on the earth’s surface to true magnetic north. The memory storage unit consists of a very lopsided cylinder of aluminum that is actually a map of the earth. At first when I saw it I thought the device had been smashed, but when you look at it closely, you realize it’s been carefully machined. There’s a stylus that can be run along the axis of the cylinder, much like a phonograph needle, that reads the radius at any point around the surface. It’s this radius that encodes the deviation of the local magnetic field. It’s quite a beautiful object. There were also computational devices in aircraft navigation systems—you can still occasionally find these in electronics swap meets and junk yards—that have ball disc and roller integrators, which were able to mechanically monitor a plane’s direction and speed and translate that into latitude and longitude. Those are pretty amazing, and I’m sure were extremely costly to produce. Of course, you can do all that now with a few lines of computer code.

A lesson given by an A...

A lesson given by an American police instructor to a class of Iraqi trainees neatly encapsulated the program’s failings. There are two clues that could indicate someone is planning a suicide attack, the instructor said: a large bank withdrawal and heavy drinking. The problem with that advice, which was recounted by Ginger Cruz, the former deputy inspector general at the American Office of the Special Inspector General for Iraq Reconstruction, was that few Iraqis have bank accounts and an extremist Sunni Muslim bent on carrying out a suicide attack is likely to consider drinking a cardinal sin.

Life in life

A video of Conway's Game of Life, emulated in Conway's Game of Life. The Life pattern is the OTCA Metapixel: http://www.conwaylife.com/wiki/OTCA_metapixel - for more information, see http://otcametapixel.blogspot.com.au/ The life simulator used is Golly - http://golly.sourceforge.net/ which has a built-in script to generate these metapixel grids (select a pattern, and choose "metafier.py" from the scripts list).
