#NixOS

On my way to Rapperswil to the #ZHF hackathon for #nixos 24.11 vikunja.

Any ways to have less headaches in nixos? Getting really tired of having to fix a whole bunch of stuff in my config everytime there is a new nixos update which I just need because I need a newer version of some random package like right now. When right now is a really bad moment to spend time on troubleshooting random stuff. This time it wasn't even a full version upgrade.

Is running the unstable branch any better?

#nixos

Woop, woop! My PR to add the NextCloud News app to the list of apps curated in nixpkgs has been merged: https://github.com/NixOS/nixpkgs/pull/357640 And it looks like this will even make it into 24.11, which would be amazing! 🎉 #NixOS #NextCloud

I'm finally putting together a list of "getting started with #nixos" videos aimed at beginners to Nix.

I'd love any feedback, positive or negative on this!

The git history of my nix config repository turned out to be really useful because I „documented“ one of the issues in a commit message: https://github.com/britter/nix-configuration/commit/bd0a7c45da51a2e5011bc26ef0e3bd5d1d33720f
Using the lazygit history search it was super easy to find this and remind myself of the issue.

git bisecting on a broken #nixos package is kind of fun detective work ❤️

We're finally planning our next #Nix meetup in #Heidelberg, which will be set between the 12th and 19th December, celebrating our meetup's anniversay! 🎂 To make the schedule suitable for as many former participants as possible, we've set up a poll. We'll open the doors at 18:00 and start talks at 19:00. There will be Pizza for celebration. 🍕

It provides a detailed overview of the most popular approaches to handling #secrets in #NixOS configurations, complete with examples

It's still as relevant today as it was last year!

Incremental builds in Nix and garnix

"[Garnix] approach is to make the derivations you want cached to output their cache (for instance in a separate output), and then to import a previous version of that derivation, and use the cached output from that version in the new one."

Shortly after the branch off for the upcoming release of NixOS 24.11, there was quite a drop in the share of Go package sources that are vulnerable, compared to the last scan 3 months ago.

For anyone wanting to add custom plugins/modules to #caddyserver on #NixOS: @vbernat released a flake to do this via xcaddy in a fixed-output derivation. Switched to it on my server today and works perfectly! More details in his blog post:

https://vincent.bernat.ch/en/blog/2024-caddy-nix-plugins

I've just switched from Gogs to Forgejo on my local server. Thanks to #nixos it took me very little time to set it up, as all the configs have the same syntax, and packagers did a great job enabling all the necessary options.

Forgejo looks super mature, and migrating my repos was a breeze. it can even migrate issues, wikis etc. from a number of git hosting solutions, including the less popular ones (like Gogs). So far, the user experience is vastly improved. Happy Sunday!

Yesterday I found the comin deployment tool for #NixOS, which works on a pull model.
This is exactly what I had been looking for and it even has some cool features like test branches.

What I didn't anticipate is to immediately end up opening a PR to it, because it ended up not working with my editor / secret management due to newline characters :D

I made a proof of concept “works out of the box”, “batteries included” Linux based desktop OS, built using #Nix and #NixOS but with flatpak support for easy installation of user applications and no knowledge of underlying Nix base OS required.
It’s simply called “deskOS”, anyone who’s interested can check it out at https://nixup.io/

I even had a EU edition in mind: https://files.nixup.io/desk-os/releases/desk-os-1/eu-edition/

Should I do something useful or move my #nixos flake with all of my configurations from flake-parts to snowfall for absolutely no reason?

The mercy of an #Anduril employee applying to become a #nixos

Is there a way in NixOS with home-manager to put a folder with space in it, for example:

home.file = {
".config/GitHub Desktop".source = ./apps/Github Desktop;
};

How do I make home-manager to "ignore" the space in the name of the folder?

#NixOS #homemanager

I published a new blog post, where I explain how I used disko and nixos-anywhere to provision a new machine at Hetzner Cloud that was previously running Debian.

https://kurau.tokyo/blog/using-disko-and-nixos-anywhere-with-hetzner/

#SmallWeb #Blogging #NixOS #NixosAnywhere #Disko

So I ran the script that @kees adapted from @bagder 's initial concept on the older×biggest repo I still make use of.

(Side-note, It would be interesting to have an AST-aware equivalent that can guesstimate the age of the constructs, rather than the age the "source" stringy-based serialization, especially since it's likely some changes refreshed some line's age, but actually only changed part of its semantics, or nothing at all.)

I ran it on the release tags (in other words, the initial point in time a numbered release was marked stable).

It took a surprisingly long amount of time, but I did not change the implementation. Maybe there's some accidentally quadratic operation that could be made faster... But also this is a legitimately big git repo, and maybe the hours it spent on the last few tags were legitimate.

Anyways, #Nixpkgs and #NixOS peeps might like that.

Just released nix-weather, a #rust cli-tool to check how many of your NixOS system’s build dependencies are in a binary cache.

$ nix-weather -n myhost -c /etc/config/

Found Nix Requisites in 8 seconds
Checked 2789 packages in 1 seconds
Found 2676/2789 (95.95%) in cache

This is useful to e.g. “check the weather” before going for an update. If the dependencies you want still haven’t been cached, it can be useful to know you can postpone an update to a later day when the weather is better on the cache.

Feel free to try it out from the GitHub mirror (it’s likely faster than my forgejo instance, and I’d appreciate saving the bandwidth).

babe wake up, I wrote about Helsing’s presence at Eurorust, winning their drone hackathon, and whether or not they’re just an “European Anduril” or a “good” defense company.

I also talk a bit about what this would mean for a Nix sponsorship policy, and what I think the Rust community can do.

And what’s the deal with Jon Gjengset suddenly working there?

There is a vulnerability in Nix 2.24.

If you're using the regular nix from nixpkgs (which the vast majority of users will be), you're still on a safe version. If you recently (after August 1st) installed nix using the nix (not NixOS) installers, or are using nixVersions.git from nixpkgs, then you need to double-check. Affected users are recommended to upgrade to version 2.24.6, which fixes the issue.

(1/6) Ich muss mich jetzt mal über die Nix(OS)-Community aufregen, also um genau zu sein das Gatekeeping in dieser Community. Seit über 3 Jahren bin ich jetzt schon dabei und versuche auch schon so lange Contributions zu den nixpkgs zu machen, was aber nun mal faktisch nicht wirklich möglich ist, wenn man keine Committer persönlich kennt.

Running into a nixos-rebuild problem. If I run `nixos-rebuild switch --build-host [my server]`, it builds, but I get the error "sudo: a terminal is required to read the password". Running `nixos-rebuild build` on its own does work, and it doesn't ask for a password since my user's trusted. It's just the final step of switching/booting into the build that fails becaus of sudo.

I did a bunch of searching and tried a dozen different fixes, but none of them worked. The only thing that worked was creating a nixos-rebuild wrapper script that basically splits a single remote switch/boot into two separate commands: a remote build, and then a local switch/boot. Basically it looks for a "--build-host" flag, and if it finds one, it runs `nixos-rebuild build --build-host [blah]`, then runs `nixos-rebuild switch`. Here's what it looks like: https://github.com/8bitbuddhist/nix-configuration/blob/89e9f95ba9daae8fe359022d74de1b84c3e312f7/bin/nixos-operations-script.sh#L98

I feel like there has to be a better way though. Anyone else run into this issue and find a less convoluted solution?

I tend to compare the #nixos and #rustlang communities a lot, because that is my bubble. Rust seems so incredibly on top of things, in comparison. Just the general way they understand social dynamics, and the way they communicate.

For example, there was an incident last year where Rust leadership had to make a public apology. I went back to read that, and there's no perfect way to do it, but it seems way better than how Nix is dealing with the Anduril controversy. https://blog.rust-lang.org/2023/05/29/RustConf.html

Signed https://save-nix-together.org primarily because I'm concerned about the people I see leaving the #nixos community. We should be pulling more people in, not pushing people away.

Making a pinned #introduction post. Hi everyone! 👋

I'm a software engineer in the Netherlands, working in entertainment. At work we build content management tools and real-time web apps, with me mostly being involved in the latter.

I do a lot of #NodeJS, #Rust, and #NixOS. I also build stuff in my spare time, like https://castling.club, and contribute to open-source projects where I can.

Let's reclaim our internet using the fediverse! 💪

Hey #nix and #nixos people!

I wrote a matrix bot for nixpkgs pull request notifications.

It‘s like the cool https//nixpk.gs/tracker.html by @qyliss, which shows you which release channels a pull request has reached.

With the bot you can subscribe and get notifications, whenever it reaches a channel instead of hammering F5 in your browser tab.

Just open a query to https://matrix.to/#/@nixpkgs-bot:maralorn.de and send "help".

Looking forward to you all stress testing it!
