The paper takes its point of departure from the research project The Contemporary Condition, to discuss the ways in which our conception of time relates to computer experimentation in art and music. Live coding is clearly a practice of time, and it seems commonsensical to say that live coding operates in, and expresses, the present but we might seek more detail on how live coding enacts a particular sense of the present in the coming together of different temporal registers. Live coding might offer some insights into our disjunctive experience of time where humans and machines run in — and out of — synchronous time, and where temporal complexity is actualized. A better (diffractive) understanding of how the present is rendered might then allow us to challenge and extend our understanding of change and action in ways that would have implications for computer experimentation and its effects.
