@anna (please don't interpret my response as an attack, that's not how I mean I'm just trying to have a conversation)
But with regards specifically to the physical accessibility (i'm referring to how you need a cane), is there something they could do?
FOSDEM is held at the ULB campus so it's partially ULB that needs to improve their accessibility as well?
(again, just asking for what could be done. I don't know enough about navigation for blind people to know what's possible)
