#FOSDEM service toot:
ULB usually allows us onto their premises on the last weekend before the semester. While we officially never plan another FOSDEM until next edition's kickoff (late August this year), it's reasonable to expect FOSDEM to happen on 2025-02-01 and 2025-02-02.
I wouldn't sign any contracts for that date, but in case you want a rough plan, now you know.
Edit: if something shifted, it would be earlier. Later than the start of the semester seems all but impossible.
