NixOS Meetup & Talk on laut

📅 Friday, August 22, 2025 at 18:00 📍 GT_, Augasse 2-6, 1090 Wien (Map) by Paul Härle

Talk: laut

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.

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:


We'll take an overview of various development tools, based on Nix and NixOS:
