This collection brings together artists, curators, programmers, theorists and heavy internet browsers whose practices make critical intervention into the broad concept of execution. It draws attention to their political strategies, asking: who and what is involved with those practices, and for whom or what are these practices performed, and how? From the contestable politics of emoji modifier mechanisms and micro-temporalities of computational processes to genomic exploitation and the curating of digital content, the chapters account for gendered, racialised, spatial, violent, erotic, artistic and other embedded forms of execution. Together they highlight a range of ways in which execution emerges and how it participates within networked forms of liveliness.
