Why is it important to create equal opportunities in computer science? Why do stereotypes matter? How to move from deficit approaches in diversity programmes? Research shows that there are structural and systematic issues that shape how people participate in computer science. However, these pervasive problems can not be addressed holistically, they require concrete interventions. To that purpose, in the last years, I have co-organised many activities, workshops, public events, and talks on equity in computer science. Some of the outcomes are interactive products that open opportunities for discussion and learning. All materials, instructions, and source code are available on FemTech.dk.
