When imperfection comes out from software malfunctions

“A glitch is a mess that is a moment, a possibility to glance at software’s inner structure, wheter it is a mechanism of data compression or HTML code.

Olga Goriunova and Alexei Shulgin, Glitch, in Matthew Fuller (edited by), Software Studies: A Lexicon, Cambridge, MA: Mit Press, 2008, p. 114.
