PhD Thesis on Software Obsolescence

From January 2023 to June 2026 I conducted a PhD thesis in Computer Science, at Lyon 1 Université Claude Bernard, under the supervision of Aurélien Tabard, in the research teams Limites numériques and SICAL at the LIRIS lab.

My PhD thesis manuscript, entitled Software obsolescence: analysis and remediation strategies is available, together with related work and publications, in section PhD Thesis of this site.

Workshops, walks and other event organizing

  • I organize and animate workshops about digital self and collective defense, about security, about freeing digital life, (un-GAFAM-isation) for everyone, workshops about coding or digital education for children, workshops about repairing computers, and other events related to digital freedom. You can contact me for everything related to this subject, I would love to help if I can.
  • I co-organised three Technopolice art exhibitions (in Avignon, 2020 and in Marseille, 202O and 2024) and three festivals on surveillance and the impacts of datacenters: festival Technopolice 2022, festival Technopolice 2023, festival Le Nuage était sous nos pieds 2024. I am interested in organizing again, do not hesitate to share similar projects with me ;).
  • I organize surveillance mapping walks and talks: we walk and talk while analysing public surveillance cameras, how they are used by the police and surveillance agencies, and how they shape our public spaces and lifes. We eventually map them in OpenStreetMap, and discuss how to circumvent surveillance. Future surveillance walks are usually announced on the public agenda of la Quadrature du Net. Do not hesitate to contact me for organizing new ones together.
