Hello,
While [Sat 2023-03-11: Nix Birthday Meetup in Vienna, Austria](https://discourse.nixos.org/t/sat-2023-03-11-nix-birthday-meetup-in-vienna-austria/25894) and [2023-04-24 (Monday) Meetup: Software Development on NixOS - Vienna Austria - #3 by phaer](https://discourse.nixos.org/t/2023-04-24-monday-meetup-software-development-on-nixos-vienna-austria/26764/3) got their own dedicated topic each, I thought it might be easier to subscribe with a single topic where new events can be posted.

Hi, next meetup around the corner. This time as a bug squashing party. Cooperatively fixing some failed hydra builds from [https://zh.fail/](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.
## Event
- Date: **2025-08-22**
- Time: open from **18:00** , talk starting at **18:30**
- Location: **[GT\_, Augasse 2-6, 1090 Wien](https://gtblank.org/)** (located on the ground floor of “Alte WU”. Indoor directions: Enter the building at the main entrance. Immediately turn right, then follow the “Ateliers”, “GT\_” and NixOS signs. Once you pass through our corridor kitchen, it’s the first door on the right. Also, just ping us on matrix if you dont find us.)
- Language: English and/or German, depending on who’s present.
## Talk: [laut](https://github.com/mschwaig/laut)
Martin Schwaighofer, @mschwaig, is going to present his project [laut](https://github.com/mschwaig/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”](https://youtu.be/UlJUpUQc9Lc).
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](https://github.com/mschwaig/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.
