New book out in 2012 on Open Humanities Press, Life in Code and Software: Mediated life in a complex computational ecology.
This book explores the relationship between living, code and software. Technologies of code and software increasingly make up an important part of our urban environment. Indeed, their reach stretches to even quite remote areas of the world. Life in Code and Software introduces and explores the way in which code and software are becoming the conditions of possibility for human living, crucially forming a computational ecology, made up of disparate software ecologies, that we inhabit. As such we need to take account of this new computational envornment and think about how today we live in a highly mediated, code-based world. That is, we live in a world where computational concepts and ideas are foundational, or ontological, which I call computationality, and within which, code and software become the paradigmatic forms of knowing and doing. Such that other candidates for this role, such as: air, the economy, evolution, the environment, satellites, etc., are understood and explained through computational concepts and categories.
