Hello,
While Sat 2023-03-11: Nix Birthday Meetup in Vienna, Austria and 2023-04-24 (Monday) Meetup: Software Development on NixOS - Vienna Austria - #3 by phaer got their own dedicated topic each, I thought it might be easier to subscribe with a single topic where new events can be posted.
It’s been a while, but we’ll do a small, casual meetup in just two days, on Thursday 2023-10-26:
Sorry for the short notice here, the best way to follow is generally our matrix channel: https://matrix.to/#/#nixos-at:matrix.org
It’s already been a year since the last one (which i forgot to post here), but we are having another meetup in a bit over a week, see Casual NixOS Meetup | NixOS User Group Austria
Hi, next meetup around the corner. This time as a bug squashing party. Cooperatively fixing some failed hydra builds from https://zh.fail/, trying to make it interesting for all skill levels.
Reminder: This is today! 
Looking foward to hack together in a few hours,
There will be space, uplink, a local nix cache, drinks, and nice people. There should also be enough power outlets but brining your own power strip (steckerleiste) might help.
We’ll also provide some very basic snacks and propose do grab some take away at nearby options together.
The next, of our now quarterly, events will happen in 10 days, Friday next week. We hope to publish it on nixos.at soon, but due to organizational difficulties, this might need a few more days. So see below for details.
Martin Schwaighofer, @mschwaig, is going to present his project laut, which is a proposed new signature format for Nix, with better security properties, in some sense meant to replace the current scheme that is used to sign cached build outputs.
The project is still work in progress, but aims to implement the ideas behind his talk at NixCon 2024 “rebuilding builders instead of trusting trust”.
In his talk he will try to explain what the point of all that work is, and what he hopes the Nix ecosystem will gain from its adoption in the future.
If there is interest, he can also talk a bit about his other project vibenix, which autonomously creates Nix packages starting from a repository URL.
Both projects are part of Martin’s research on supply chain security at JKU in Linz, where he is working on his PhD.
There will be room for casual chat on all things Nix(OS) after the talk.

It’s now on our website, in case you want a link to send to friends & colleagues:)
Reminder: this today!
