Chapter 1 shows the importance of informal but physical meetings around the subject of computer security. By understanding informal groups like hackerspaces and DevOps meetings, it is possible to observe vernacular experimentation with computer infrastructures: using private spaces to conduct experiments that are considered unnecessary or too costly within formal organisations. This chapter gives examples from interviews conducted among such groups and connects them with security-privacy debates that happened in the European Union around the General Data Protection Regulation (GDPR).
