“Airbnb is a global hotel filled with the same recurring items. Bed, chair, potted plant, all catered to our cosmopolitan sensibilities. We end up in a place that’s completely interchangeable; a room is a room is a room.
An algorithm finds these recurring items and replaces them with the same items from other listings. By clicking them, you can jump between rooms and explore the global hotel. There are many homelike places.
Outcome of a week-long web scraping workshop led by Jonathan Puckey at Non-Linear Narrative, a masters programme at the Royal Academy of Art The Hague.”
This device allows for the automatic generation of a Gaussian curve (position of the balls at the bottom. The artistic problems of the dérive occur at the same level as the relatively unpredictable path of each ball.
“As we know, everyone is now talking about the virtual, i.e., computerized museum, and that must be the reason why a media historian has been invited to Barcelona.” Friedrich Kittler on the museum of art and digital archiving. (more…)
Duchenne was based at the Salpêtrière hospital in Paris, where he researched muscular electrophysiology—the perceived electrical dysfunction underlying neurological conditions, ranging from strokes and epilepsy through to the more questionable areas of hysteria and insanity. […] The afflictions of the inmates of the Salpêtrière made them perfect candidates for Duchenne’s research and documentation: muscular paralysis and facial anaesthetics made them extremely malleable. The flow of sustained electrical currents allowed Duchenne to overcome the limits of photography’s then long shutter speeds to have his sitters ‘hold’ a pose for an extended period. (more…)
In this demo video, a programmer works interactively with open CV. As the code is altered, a window displaying the results of the computation is continuously updated. The demonstration ends as the programmer connects a camera and then places object (playing cards) on a table, manually isolates the pixels of the card, then uses the captured sample to locate and outline the same card in subsequent frames of the live video.
Although early users of database technology were predominantly large institutions, the database was also a key technology in the populist vision of personal computing generated by microcomputer fans, researchers, hobbyists, and entrepreneurs in the 1970s and 1980s. Informed by science fiction sensitive to the authoritarian use of database technology, these personal computing advocates hoped that experience with small database systems might sharpen popular critique of mass-scale information processing efforts. As database design receded from the desktop in the 1990s, however, the populist promises were largely forgotten and the database became an exclusively institutional technology once again.
A social history of database technology situates the web’s massive databases among more than a century of mass-scale information processing systems. Evidence of popular anxiety recurs throughout this history and indicates that non-specialists often struggle to apprehend the limits of database technology and may alternately over- and under-estimate the extent of mass data collection and the types of analytic outcomes that are possible. Meanwhile, the cautious optimism of the microcomputer era points to a latent database populism that may yet be revived should users grow sufficiently frustrated by the lack of transparency among large, data-driven institutions.
We have described each of the operations on the retinal image in terms of what common factors in a large variety of stimuli cause response and what common factors have no effect. What, then, does a particular fiber in the optic nerve measure? We have considered it to be how much there is in a stimulus of that quality which excites the fiber maximally, naming that quality.
The operations thus have much more the flavor of perception than of sensation if that distinction has any meaning now. That is to say that the language in which they are best described is the language of complex abstractions from the visual image. We have been tempted,for example, to call the convexity detectors “bug perceivers.” Such a fiber [operation 2] responds best when a dark object, smaller than a receptive field, enters that field, stops, and moves about intermittently thereafter. The response is not affected if the lighting changes or if the background (say a picture of grass and flowers) is moving, and is not there if only the background, moving or still, is in the field. Could one better describe a system for detecting an accessible bug?
