In the good tradition of the ERNI Community, at ERNI Switzerland we do high altitude hacking and hiking in the mountains in Wissifluh, Vitznau every year. This event has been taken over in other sites as well, e.g. in Slovakia. During the past Hack’n’Hikes also colleagues from other sites joined us to use the opportunity to meet ERNI mates in a very casual atmosphere and to have lots of fun, nice talks and to enjoy being in nature. Everyone is invited to contribute to the ERNI Community Projects around IoT and ML on Edge: UX specialists, ideation enthusiasts, agile coaches, POs, electronics tinkerers, and coders.
