The effects of software (code) on the spatial formation of everyday life are best understood through a theoretical
framework that utilizes the concepts of technicity (the productive power of technology to make things happen)
and transduction (the constant making anew of a domain in reiterative and transformative practices). Examples
from the lives of three Londoners illustrate that code makes a difference to everyday life because its technicity alternatively modulates space through processes of transduction. Space needs to be theorized as ontogenetic, that is, understood as continually being brought into existence through transductive practices (practices that change the conditions under which space is (re)made). The nature of space transduced by code is detailed and illustrated with respect to domestic living, work, communication, transport, and consumption.
