Dear colleagues, We invite short submissions to an Online Critical Computing Gathering, to be held on June 24, 2026. You can read the full CFP here <https://criticalcomputing.cc/cfp_online>. This fourth installment of the Critical Computing gathering <https://urldefense.com/v3/__https://criticalcomputing.cc/__;!!LIr3w8kk_Xxm!uwjKXKSfddDiYfU7Fv1d33eIMOwxVVsjS963O4VaxL89fp7cFDDwGbP1XTCNBYEeIj0bEuu0af8E6cmm9Sx3kY0$> (after events that were part of Aarhus, 4S, and IFDIK in 2025) will continue to experiment with a threaded format: participants will share short, in-progress works that respond to one another before, during, and after the workshop, leading to co-authored or multi-voiced works. Participants prepare a short, exploratory contribution (800–1,200 words, or equivalent media) focused on a term, concept, or problem central to their work in critical computing. These are not expected to be complete papers or fully worked-out arguments. Rather, they are starting threads. We seek provocations, fragments, or in-progress reflections that can be taken up and woven together with others. We welcome contributions from scholars, practitioners, artists, designers, technologists, and activists who engage critically with computation in their work. There will be two sessions of the online gathering to accommodate time zones. Submissions are due March 31 2026 via this form <https://docs.google.com/forms/d/e/1FAIpQLSeZVnZVYvcNgnVwTNSvsNaqkCotLtHfW4DOzKzbkY_iBtIMRg/viewform> . Please share this call widely with your networks and communities. Kind regards, Alex, Bono, Daniela, Lucy, Luis, and Nassim a -- -!-…..-!-..…-!-…..-!-…..-!-…..-!-…..-!-…..-!-…..-!-…..-!- Daniela K.
