This article discusses the notion of subject in psychology. The scenario for our discussions will be the contemporary practices of digital artifacts use and the less observed context of developing softwares. In doing so, we elaborate how the actions of those softwares users and developers regulate each other as they become the subjects of human-computer relations. We propose a perspective of subjectivity that articulates a dialogue among Vygotsky's thought, Bakhtin's Circle and Benveniste linguistics. In such a perspective, software users and developers are both authors, and the computer interfaces they create, usually taken as code alone, are understood as enunciations that trigger a dialogical dynamics. In the end, we show a subject who continuously emerges from the relations established with others subjects and other discourses, whose voices are sometimes encapsulated as images and words on a computer interface.
