DataBeers is a recurring FREE event open to the general public. The aim is to bring people together to talk about any and all aspects of data in a relaxed environment lubricated with some beers.
It started in Madrid back in 2014 and has since grown and spread to more than 18 cities around the world. You can see the map here.
A central part of each meeting is a selection of short (<7min) and entertaining talks about data.
