Notes
Talks: data-related developer rooms only (FOSDEM has ~1105 schedule entries this year). Included rooms: Cloud Native Databases; Data Analytics; MySQL; PostgreSQL; HPC, Big Data & Data Science; Low-level AI Engineering and Hacking. Plus main-track talk "Databases in the AI Trenches" (Bruce Momjian). Devroom welcome sessions and speaker-less discussion slots omitted. Affiliations come from the FOSDEM speaker bio on the archived schedule (null when the bio is empty or names no employer; some bios carry over from earlier editions). 96 talks, 127 speaker rows, 95 with affiliation. Videos are video.fosdem.org recordings and slides are the attachments/links on each event page, taken from the schedule XML. The PostgreSQL devroom is listed here; the separate paid FOSDEM PGDay (Friday) is tracked as fosdem-pgday.
