Hei!
We’re starting a new Nix/NixOS user group in Oslo, here’s the meetup page:
There seem to be a whole bunch of people who are either using Nix, or are interested in Nix and related problems in the city - my plan is to launch this group to socialise, share knowledge, have some interesting talks and maybe hack nights / install fests when the opportunities arise.
If you’re in or close to Oslo, join the group and, well, meet up! 
As the summer vacation period is starting here and the country is shutting down for the next month and a half, we’ll probably not have a proper talk before August - but I’d like to do a social event before then just to get the ball rolling.
Cheers!
