We have become accustomed to casually giving up factors of two or ten or more with our choices of tools and libraries, without asking if the benefits are worth it. performancesoftware
The drift The Situationists were also practitioners of a special urban-analytic walking style, the dérive—the “drift”—which Debord described as “a technique of transient passage through varied ambiences. The dérive entails playful-constructive behavior and awareness of psychogeographical effects; which completely distinguishes it from the classical notions of the journey and the stroll.” “In a dérive,” Debord deadpans, “one or more persons during a certain period drop their usual motives for movement and action, their relations, their work and leisure activities, and let themselves be drawn by the attractions of the terrain and the encounters they find there." The dérive joins the free association of surrealism, the LSD of hippiedom, and cinematic montage as tactics for overcoming the fixity of received ideas of order and logic. By putting progress through the city into a state of constant indeterminacy, it represents a schooled “style” of being lost.
