Hi, Since 2007, Debian has been represented (almost every year) with a booth at the yearly T-DOSE conference near Eindhoven.
T-DOSE is a volunteer driven, no registration needed, free entrance, 2-day conference. A bit like a human scale FOSDEM :) See https://nl.wikipedia.org/wiki/T-DOSE and https://t-dose.org/ . We're looking for volunteers to run a Debian booth @ this years' T-DOSE, Sat 31 May and Sun 1 June ("Hemelvaartsweekend") at the Weeffabriek in Geldrop (near Eindhoven). You don't need to be a Debian Developer for that, btw. I'd be happy to help you in getting stuff arranged. Bye, Joost
