This paper explores the specific questions raised for social epistemology encountered in code and software. It does so because these technologies increasingly make up an important part of our urban environment, and stretch across all aspects of our lives. The paper introduces and explores the way in which code and software become the conditions of possibility for human knowledge, crucially becoming computational epis- temes, which we share with non-human but crucially knowledge-producing actors. As such, we need to take account of this new computational world and think about how we live today in a highly mediated code-based world. Nonetheless, here I want to understand software epistemes as a broad concept related to the knowledge generated...
