In this course taught for the first time in 2022 we engaged knowledges produced by and for women, queer and disabled people within the fields of critical computing and computer science. Beginning with trans-feminist methods that focus on participation, inclusion and collaboration to set the conditions for the course. Together we trace texts and work with critical pedagogical methods of learning following historical and theoretical frameworks from transfeminist technoscience, crip technoscience and feminist computing. This course teaches computing from the perspective that histories have often been actually hirstories or theirstories where women, queers and disabled people have been agents of change, action and practice who have and continue to actively shape the field of computer science. One example in the course is the great project of the Open Dyslexic Font which is used in the image to announce this course and can be found and downloaded for free, here.
