Come and join us at our NixOS (https://nixos.org) meetup. You might already heard about the purely functional Linux distro but haven't found the time and support to try it out yet.
We are not a structured event and usually are not having any talks. Usually we are in a pub like atmosphere and fixing NixOS issues. Come around if you have any questions or just want a little tour of Nix or NixOS. You can usually identify us by the NixOS stickers on our laptops.
If you can't find us, ask for lassulus in real life or on irc.freenode.org
You can bring an empty USB stick and we can install a bootable copy of NixOS on it. That's a great way to safely discover a new system. Deep knowledge of Linux and/or functional programming is not mandatory.
