NixCon 2019

25-27 October
Talks Discussions Hacking
160 people / 80 for Hackday


NixCon is a community-oriented conference for contributors and users of Nix and NixOS. It's about sharing experiences, inspiring people and discussing future development.

We would like to learn about how you use Nix and NixOS in your organization and what you are currently working on.

The growth of NixOS as a project brings its own challenges and we would like to know how you think the user experience can be improved and how NixOS can be scaled.


Call for Participation

The Nixcon 2019 CfP is now closed.

Program - 25-26 October (Fri/Saturday)

Have a look at the program.

We will have plenty of space for talks and socializing. During the conference days we have three rooms. On big room with enough space for everyone and two smaller ones for a subset of all attendees.

Hackday - 27 October (Sunday)

The Hackday is a self-organizing event after the conference. It's an opportunity to network, hack on projects and ideas that arose during the conference, and discuss plans for the rest of the year.

The location is the same as the conference but with just one room and a different table layout, limiting the number of attendees to 80 people.
