Hi all, I am curious to what peoplle carry in their bags at an event as FOSDEM. Anybody interested in a shared blog, Twitter hastag or something else where visiters of FOSDEM can share what they drag around. Reference images are: https://www.google.nl/search?q=what+is+in+my+bag+tech&tbm=isch What are your ideas for this? It could even be offered via FOSDEM apps. Regards, Pander
