The Geeks Anonymes Liège is a developers group with monthly talks for all the developers profile into ULiège (computer scientists, engineers, biologists, ...) and for IT professional.
Since 2014, I'm a regular participant from these monthly talks and I gave four of them :
FOSDEM is a free event once a year for thousands of software developers to meet, share ideas and collaborate.
I gave a talk about Cytomine in 2016.
Like Wajug and Devoxx to learn new evolutions of this fast changing field.
