I think in need to get rid of gnupg out of software stack... whenever I try software like age or deltachat I realize how bad it is.

@y3mz @pinpox k3s works well on NixOS for a couple of years now. I personally still have the nixos firewall disabled for it. Also there seems to be ways around that.

@y3mz @pinpox so far we only used local volumes i.e. based on lvm, so I don't know what the state of this is.

After a lot of testing, I decided it's time to release envfs 1.0: https://github.com/Mic92/envfs/releases/tag/1.0.0 This is a filesystem that make shebangs with hardcoded paths to /usr/bin work on NixOS

@davidgerard @bmcgee84 we will make it opt in nixpkgs for sure.

@baloo both musl and glibc have a lot of internal state set up at startup. You cannot even set up one glibc linked application and load another glibc at runtime. That's why I ended up using the nolibc library from the Linux kernel when building nix-ld.

Nixpkgs evaluation now needs 15% more CPU time thanks to rust ecoysystem... https://github.com/NixOS/nixpkgs/runs/12279178729 #nixos

@Ericson2314 @fgaz @zimbatm not so confident there are many volunteers that want to deal with a arcane perl code base that has a lot of responsibilities.

@aldo I always wondered what those turning knobs in the corner of your mechanical keyboard do?

Tvix vs nix evaluation of the hello package on a AMD EPYC 7713P: Summary 'nix eval --impure --expr 'with import <nixpkgs>{}; toString hello'' ran 14.26 ± 0.18 times faster than './target/release/tvix -E 'with import <nixpkgs>{}; toString hello''Full report: https://gist.github.com/Mic92/2edb7d1afa861dffd2f601f1de78cb87

I just got told. That nix eval is eager and I should compare it to nix-instantiate instead. New data is in the gist.

A bit delayed, but now also nixos images that power our unattended installers are built from NixOS 23.05: https://github.com/nix-community/nixos-images/releases/tag/nixos-23.05

We are at this point where you need a 10GB swap file to evaluate nixpkgs for nix-index-database on github runners who are equipped with 8GB RAM. Maybe it's time to stop adding things to nixpkgs until those performance issues are under control.

@sandro the naive flamegraphs of nixpkgs are actually quite hard to interpret. ninjatrappeur built some with a patched nix that are better... Maybe there is something. Also I have the feeling it's rather a "death by a thousand papercuts" kind of problem.

Tipp: If you are low on memory and you need to evaluate a lot of #nixos machines, try using the pkgs argument to make nixos share the same nixpkgs instance for all nixos machines: https://github.com/TUM-DSE/doctor-cluster-config/pull/322 Saves 45% of memory in evaluation in our real-world deployment.

I cannot recommend to use XFS for anything that is not a filesystem benchmark. On crashes it will reliable truncate files to 0 bytes. Had to fix my git repositories manually.

@picnoir I use a shared task list in nextcloud. There are good task manager for both android and iOS that are compatible with that (built-in in iOS). And you can also share contacts and calendar entries.

I created over Christmas a new more reliable method to package binaries with Nix: https://github.com/Mic92/wrap-buddyThis is a drop replacement to `autoPatchelfHook`. Instead of complex patch operations on the elf sections, it replaces the entry point of an elf binary to it's own minimal loader, a bit like how the UPX loader works. Advantage of this approach is that, the layout of the binary at runtime is fully preserved.
