Martin Schwaighofer 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.

- Date: 2024-04-09
- Time: from 18:00
- Location: Metalab, RathausstraĂźe 6, 1010 Vienna (at least one person will wear a NixOS-themed hoodie or shirt and you can also ping us on matrix if you find it hard to locate us)
- Language: English and/or German, depending on who's present.
- Presenters:
- @phaer will do a introduction on nixos-anywhere and disko, explain why they are useful & roughly how they work.
- @Krezzlu will do a demo on impermanence (with disko), explain why you might want to use it and give pointers to further resources.
The plan is to have a chat while people arrive and start the program with a round of introductions before talks & demos.
While the inputs focus on declarative disk partitioning & provisioning NixOS, we try to keep talks below an hour to leave plenty of time for all kinds of questions, discussion & chats during the rest of the evening.

Software Development on NixOS
NixOS is awesome for packaging existing software, with helpers for many common build systems.
From an operators's perspective, it really shines with composing software. How about the developer's perspective?
Nix is a programming language so it should be able to adapt to many use cases.
A developer wanting to use Nix from the ground floor up, may care about various questions:
- What tools are there to support software development?
- What about support for non - NixOS developers?
- How to use Nix as a build system?
- How to do the pipeline to production?
We'll take an overview of various development tools, based on Nix and NixOS:
- flake direnv
- numtide/devshell
- devenv
- flox
- nixos-container
