Henri Lefebvre (1991), The Production of Space, trans. Donald Nicholson-Smith, Oxford: Blackwell.  

'The ruling class seeks to maintain its hegemony by all available means, and knowledge is one such means. The connection between knowledge (savoir) and power is thus made manifest, although this in no way interdicts a critical and subversive form of knowledge (connaissance); on the contrary, it points up the antagonism between a knowledge which serves power and a form of knowing which refuses to acknowledge power.' (Lefebvre, 1991: 10)

This dialectical approach to knowledge articulates the way I seek to describe the articulation of code and the technical apparatus.
