For #NixOS Unstable users:

We're about to stop shipping VPN plugins by default with #networkmanager.

This means you'll need to explicitly configure the ones you need via `networking.networkmanager.plugins`.

In fact, if you are relying on a VPN via #NetworkManager go and do that now to prevent any interruptions.

@sandro @misterjoshua I mean the fact that you as an end user of the OS can just mess with and fix stuff like this is an absolute superpower of #NixOS. Without much hassle you can turn the innermost parts of the OS upside down as you like, for your own machine, *reproducibly*, once, and stop thinking about it, because it integrates (and stays!) directly in the roots of the OS, and sharing your work including context and timeline is as easy as a git push.

Today I've been fighting again with this absolutely stupid :nixos: #NixOS bug that dates back nearly 20 years now, which prevents you from naming an executable 'log'. Yes, it is NOT possible on NixOS. 🤦 🤦 🤦 And working around it is beyond frustrating. Fixing it requires a mass rebuild, so it's not that simple. 😩 😂 It's so terrible but also hilarious...

Hey #NixOS people, do you think it's possible to make a bootable iso nix installer that will simply confirm if they want to wipe this computer and install nix, and if they type Y, it will do a completely unattended format and install of NixOS with all the settings preset?

(And obviously run nmtui or something first to connect to wifi)

And this can be all terminal

IMPORTANT for #Lix users: look out for this critical bug that can bork your system: https://lix.systems/blog/2025-06-27-lix-critical-bug/

They give you other ways of fixing the issue, like patching Lix. But if you need a quick fix, you can downgrade, but that will make you susceptible to a security CVE (granted there's no known attack vector yet). If you want to downgrade but don't know how, here's a reference for Flakes: https://codeberg.org/8bitbuddhist/nix-configuration/src/commit/d5d7eebf169fc98c5fe47d578833498b77bf4ac5/flake.nix#L31

Aaah, `nix-store --query --referrers <the-bad-coreutils>` for the win, it was only referred to by a Python package from an overlay where I used prev.coreutils instead of final.coreutils. No idea why that causes a rebuild but okay. Happy that it works now 😌

Yann Büchau

#NixOS driving me nuts right now. Keeps rebuilding coreutils for aarch64-linux when building for my RPi (but it's definitely in the cache, so it has to be some obscure special version deep down), it takes ONE.FRICKING.HOUR just for it to fail on ONE 'test-free' (qemu: uncught target signal 11 (Segmentation fault) - core dumped). 😠

Also, I can't override what I don't find, wtf...

I need the help from #Nixos community.

My PC freezes, but I haven't figured out yet what is it. My current hypothesis is Nvidia drivers + Firefox + Wayland.

I'm currently running Firefox in XWayland. But I've seen it happening again even on this mode.

I don't see anything telling me the issue on journalctl. I wonder WHERE to look for stuff for?

The funky thing is the sound stops and the wifi goes away too, networking goes entirely down. USB ports stop working. It's a fully-fledge crash.

Which is probably why I can't find any logs. This is what I see in dmesg

OK after testing on a test Mastodon instance I think I am going to probably(90% chance) move to NixOS for my instance(esper.lol).

I do like the setup, centralized file, I can declare all the settings I want in one place and, I can easily move to a new server with this config FAST if need be.

Using social.spiritsandsuch.lol to test my setup, seems great so far. Automated backups, s3 storage, Declared Sidekiq processes, web, streaming, etc.

If I do move it will be on 4.4

Added everything in as described on the wiki and BOOM! The instance came up and I could create an account.

I still know NOTHING about Nixos other than some YouTube knowledge but I kinda feel like this can replace Ubuntu for my servers that I run.

Our fleet of #multicopters is growing as we prepare for our part in the #TeamX¹ campaign in 🇦🇹 #Austria next month.

We'll provide valuable in-situ #temperature, #humidity, #wind and #turbulence measurements with our custom meteorological PARASITE system on multiple copters in parallel across the Inn valley. This data will help with understanding wind shear in mountainous regions and eventually improve
#mountainWeather forecasts.

Our PARASITEs carry several atmospheric sensors and we derive the turbulent 3D wind vector from the copter movements. @nobodyinperson suggested to name them like #BugsLife characters 🐛😉. He put a nicely customized ❄️ #NixOS in there to stay in control of the software, integrate it all and sync data e.g. to a #forgejoAneksajo instance (#forgejo with #gitAnnex support), our own or the one of @fzj_rdm during the VITAL campaign last year.

Hmm wondering if anyone can help me with a #linux question.

I'm running #nixos with #gnome 48, and even though I disabled automatic updates and notifications in Gnome Software.. still, every day, I get a notification saying "Updates are out of date" (even though when i click on it, it shows no updates)

Oddly enough, this is also happening on my project #nixbook , which is cinnamon (but still running gnome software)

How can I stop this!?!?!

I love using #Nix and #NixOS, and if it works it works great, but my biggest frustration with it is that whenever something doesn't work it turns out
to be a deeply cursed rabbit hole of a problem that's utterly undebuggable due to either bad error messages or a hard to understand and badly documented spaghetti mess of code, dependencies and components.

(For the source this current outbreak of frustration or if you want to try to help me take a look at https://discourse.nixos.org/t/removing-kwallet-from-system-closure-as-dependency-of-nextcloud-client/65601 🙃)

#NixOS #nixpkgs #raspberrypi #Pihole

After more than 5 years, Pi-hole is now finally available in nixpkgs/NixOS!
https://github.com/NixOS/nixpkgs/pull/361571

The package request was one of the most upvoted nixpkgs issues.

There is also a NixOS module available, you can find the options here: https://search.nixos.org/options?channel=unstable&from=0&size=50&sort=relevance&type=packages&query=services.pihole

There were other good options with comparable functionality before (adguard-home, blocky), but it's still nice to have for people migrating from non-NixOS pi-hole.

Sandro

TIL: You can do the following with submodule style options in #NixOS

```
services.prometheus.exporters = {
node = { config, ... }: {
enable = true;
firewallFilter = mkFirewallFilter config.port;
firewallRules = mkFirewallRule config.port;
openFirewall = true;
};
};
```

Without this pattern and when using `config.services.prometheus.exporters.node.port` you run into an infinite recursion.

OK #nixos friends. What do flakes offer me realistically if all I want to do is make sure all the desktops in my house have the same config?

Here’s my dumb #nixos question of the week. How can I, as administrator of a particular computer with multiple users using Home Manager, update another user’s environment? I can edit the home.nix file, of course, but how can I do a “remote” home-manager switch that updates another user’s packages and settings on their behalf when they don’t have admin rights?

The newly installed #NixOS system passed the “will it work in production?” test with new files successfully being saved by users (same IP address, same samba passwords) 🥳

Fun to see the CPU being, like, totally idle — I guess 20 MB files mean nothing to a modern computer anymore :)

I just cross-compiled a whole #NixOS installation with zero build errors. That's wild.

Also, it's running on an old #Ouya console. 🔥

#nixos #nix #nixpkgs #nixstore

I've spent the last ~3 months using Nix and NixOS, and I've run into quite a few pain points.

I come from an Arch Linux background, very bleeding edge and I was surprised to find so many outdated packages in the Nix ecosystem. The state of nixpkgs also feels concerning, with 5000+ open pull requests (https://github.com/NixOS/nixpkgs/pulls).

The common argument that “Nix has more packages and no duplicates” also doesn’t hold up in my experience, for example, there are three different versions of signal-desktop in the Nix store with three different Versions.

Another frustration: if you want to install sublime4, you have to enable allowInsecure = true; because of some TLS issues, which doesn't sit right with me.

So now I'm wondering:
Am I just doing something wrong?
Or is Nix just not for me, since I lean more toward the bleeding edge side of things?

I'm trying to manage a shared setup for both nixos (amd64) and darwin (aarch64) from a single repo.

I really like the declarative idea, but right now I’m feeling more frustrated than productive.

Would love to hear from anyone who’s been in a similar spot or wants to chat about it.

Couldn’t help myself and converted another VM to #NixOS 😅

This one used to be an OpenMediaVault samba appliance that later grew in scope and now runs a systemd service or two.

Converted it to NixOS before things escalate. The initial setup and samba config was done in about 30 minutes. The services took longer.

This was a good move as it made setting up vsftpd (for receiving scans over LAN from a network scanner) for testing purposes quite easy :)

Also sops-nix is cool (will blog about it!)

#NixOS people. I have a rather baroque set of requirements for my router, which I'm thinking of upgrading. The plan is to virtualize it onto a container in my Proxmox cluster.

But, the firewall is a custom nftables script, it runs Squid with custom config file, it runs yggdrasil with custom config, it has wireguard tunnels to multiple sites, etc. The configs for those things are in systemd network files, or /etc/squid/squid.conf or /etc/nftables.conf or whatever.

How I like to install NixOS (declaratively)

For one of my network storage PC builds, I was looking for an alternative to Flatcar Container Linux and tried out NixOS again (after an almost 10 year break). There are many ways to install NixOS, and in this article I will outline how I like to install NixOS on physical hardware or virtual machines: over the network and fully declaratively.

#Lix just merged an experimental integer coercion feature.

That's useful if you want to interpolate an integer into a string. In #nixlang you previously needed to explicitly call `toString` to achieve that cast.

And checking my personal configuration it looks like I can drop all `toString` usage in my configuration with this.

omgz current Git main for Lix now has a new `coerce-integers` experimental flag to allow e.g. "${ip}:${port}" instead of requiring the dumb "${ip}:${builtins.toString port}" (raise your hand if you always forget the toString call).

Time to use it everywhere I can, compat with other implementations be damned.

@raito @rriemann @Linux @eu_os this PR is great, it covers what I meant. “Nix as LEGO for building your own Linux based OS”. I like that analogy. It’s a good one. I must repeat that I am not advocating #NixOS as a base OS for EU OS proof of concept. I suggest looking into using #Nix to build and maintain a lean base.

We have an open PR in the EU OS gitlab at https://gitlab.com/eu-os/eu-os.gitlab.io/-/merge_requests/6 .

I am still afraid NixOS may not yet be battle-tested in the public sector. I'd like to add an example to https://eu-os.eu/use-cases#notable-migrations if you have one.

@[email protected] · Reply to Linux Is Best's post

@Linux @rriemann @eu_os I agree with the point raised about #NixOS and have suggested looking into this a few times wrt EU OS. Using #Nix as build tool really is a very unique approach to building a Linux based OS and completely cuts out the notion of a “distribution”. It takes a more direct path from the upstream source code (kernel, systemd, …) to a working OS. Thus entirely sidestepping the raised concerns about another distro used as a base.

You know, going forward, it is my intention to actively campaign against EU_OS. - Sorry.

I do not believe you have, currently, the best intentions, and I believe your concept is misleading in a false sense of security. You can, choose to become independent, as others have, NixOS, for example. Or you're just promoting an American operating system, rebranded. I would not recommend your OS, anymore than I would recommend China's Deepin Linux or Russia's Astra Linux.

You seem to want to ignore this obvious point, and so I do not believe you're acting in good faith.

This meme uses the "No Thanks" Russian meme template, which features a drawing of a man in a suit holding his hand out in a "stop" gesture. In this version, he is labeled "Other Linux users." Another hand, coming from the bottom left, is holding out a glass labeled "NixOS," and this hand is labeled "NixOS users." In the bottom right, a fork is visible, also implicitly offered by the "NixOS users" to "Other Linux users." The meme's humor comes from the implication that NixOS users are very enthusiastic about their operating system and try to convince "other Linux users" to adopt it, while "other Linux users" are depicted as resistant to the idea.

On the nixpkgs side of things, the no-broken-symlinks hook was added to catch builds containing dangling or reflexive symlinks, as these are indicative of problems with packaging. The hook can be disabled by providing dontCheckForBrokenSymlinks = true; as an argument to mkDerivation.

substituteAll and substituteAllFiles have been deprecated in favor of replaceVars and will be removed in the next release.

And I already posted about the improvements of lib.packagesFromDirectoryRecursive] being able to construct nested scopes matching the directory tree passed as input..

Finally, a NixOS module has been added for ncps, a Nix binary cache proxy service implemented in Go using go-nix. It's available as [services.ncps](options.html#opt-services.ncps.enable).

Paul Meyer

To avoid delaying user logins unnecessarily the multi-user.target is no longer ordered after network-online.target. System services requiring a connection to start correctly must explicitly state so in their service configuration. Really happy to see this change, it will likely speed up boot times for many users.

Paul Meyer

The nixos-generate-config command now supports a optional --flake option, which will generate a flake.nix file alongside the configuration.nix and hardware-configuration.nix, providing an easy introduction into flake-based system configurations.

It definitely is nscd/nsncd.

And since "disabling this is strongly discouraged" (as per the #NixOS docs), I guess you're stuck with full-blown containers if you want to prevent DNS leaks ...

daniel

On #NixOS, is programs (using gethostbyname) running inside of network namespaces leaking DNS requests a known issue?

This happens despite the nsswitch.conf (of the namespace) having the following line:

hosts: dns [!UNAVAIL=return] files

So no accidental resolve leak.

The entries in the resolv.conf (of the namespace) simply aren't used.

My guess is that this is happening because of nscd/nsncd.

Okay the fastest workaround I found for now is:

# build laptop's system on the server (a lot already built, doesn't take long)
server$ nix build .#nixosConfigurations.$LAPTOP.config.system.build.toplevel)"

# copy system manually from server to laptop
laptop$ nix copy --from ssh://server "$(nix eval --raw --apply builtins.toString .#nixosConfigurations."$(hostname)".config.system.build.toplevel)"
# then nixos-rebuild as usual
laptop$ nixos-rebuild --flake . --use-remote-sudo switch

¹https://nix.dev/manual/nix/2.24/package-management/ssh-substituter.html

Has *anyone ever* gotten :nixos: #nix to automatically fetch things from another of your machines instead of cache.nixos.org and/or rebuilding everything _again_ locally?

The manual¹ claims one can use --substituers ssh://yourmachine, but (of course) that doesn't work. Terrible or no error messages, that weird 'SSH stdout first line:' message, different port only settable via NIX_SSHOPTS='-p 1234', hangs indefinitely at `querying info about missing paths`...

I am pretty new to #NixOS - but while I wait for my first PR (https://github.com/NixOS/nixpkgs/pull/400046) to be reviewed, I want to use the package already.

currently I add -I nixpkgs=... to my rebuilds but it feels wrong. Especially since #nix seems to be made for flexible things like this.

Where would I start finding this out? Is it advisible to get familiar with nix lang first and THEN try stuff like this or are there good resources for 'learn as you go' - which usually works better for me.

Developing #Java with #Gradle on #NixOS and needing multiple or different specific #JDK(s) (toolchain versions) might be a tricky with NixOS, as it's not following FHS and installed JDK(s) aren't placed in standard Linux locations.

Sharing a configuration to be added/imported into `configuration.nix`, that makes multiple JDK(s) available in /opt/java, and therefore Gradle's JDK auto-detection picks them.

Thanks to the awesome @leftpaddotpy and 9999years (I don't have their fedi?!), we now have #Lix 2.93.0: https://lix.systems/blog/2025-05-06-lix-2.93-release/.

The release notes contain a lot of goodies, nevertheless, another cool thing about it is that it contains a tremendous effort from eldritch horrors to rewrite the I/O and threading model to KJ: the Cap'n'Proto asynchronous runtime.

This unveiled a massive amount of hidden ordering constraints in the codebase, very hard to debug.

Hii~,

I’m quantenzitrone or short Zitrone, a mostly male #human.

I just moved here from #fosstodon because of some moderation drama there leading to some instances defederating, also because i wanted to switch to an instance hosted in Europe.

I like computers, especially those running #GNUlinux especially #NixOS. I’m currently setting up my #homeserver with NixOS. I maintain a few packages in nixpkgs.

I like #programming, especially in #Rustlang, sometimes when programming in other languages I notice that they are in fact not Rust. Sometimes I complain about it on Fedi

I may meow at you especially if you’re cute and/or meow-at-able

I study computer science at @uniheidelberg@xn–baw-joa.social.

You may meet me in the #RaumZeitLabor or at the #GPN and #ChaosCommunicationCongress. This year I also plan to be on the #MRMCD and maybe #NixCon.

My favourite logic gate is XOR.

I really like the easy way that NixOS enables you to get rid of all cruft through one config file. Discover, kwallet and elisa are part of the Plasma metapackage. Removing them in other distros gets you the warning that you, by removing them, are actually removing Plasma. Not so in NixOS. a clean working Plasma session remains, without those unnecessary addons. Re-adding them is one simple edit away.

Yay! My recent apparmor update PR to #nixos [1] has now hit the nixos-unstable repository! This means 4.1.0 is available, with various improvements.

With that PR, i completely rewrote the #nix packaging. It now supports pkgsMusl, pkgsCross and pkgsLLVM. It has the build checks flipped on, and packaging is massively simplified.

Making all this work wasn't trivial, and some oversights were made. Those have been corrected in follow-ups, though the functionality should be available already. Do report issues with this update!

Sadly, 4.1.0 does not yet bring the needed optimizations to the alias system that are necessary to efficiently confine all of the nix store effectively. That part is still a WIP.

I also have to say: I am impressed with apparmor upstream. While doing this update, i noticed the parser check suite failing when compiling against Musl libc. Apparmor is maintained by cannonical devs, ubuntu does not use musl. Yet they were willing to listen, debug and fix these issues. While not everything has been fixed yet (this is an ongoing effort), it is nice to see upstream developers wanting to support the "weird" platforms like musl nixos.

@aires I'm already using it! Although not because it's made in rust, purely because I found some Nix tooling really doesn't accommodate doas 🙄

I can't remember them all, but I know deploy-rs was the one that "pushed me over the edge", as it would only work with sudo, so I went with the more minimal sudo-rs implementation.

That said, what I've seen mentioned elsewhere which I'm really interested in, is run0

Although it doesn't seem to work on NixOS, unless anyone's aware of any workarounds? This is the most recent (Nix oriented) post I've seen.

Great fun I just had with Nixbook, a project by Mike @codemonkeymike , turning your computer in a Nix-powered Chromebook. Restarted 8 years ago with Linux Mint and have been on a great Linux journey since. and yes, I've done them all (except LFS and some other curiosa). Nice to be on Cinnamon again. Did Nix as well, and still had those configuration.nix files lying around. Don't really need them, all just works. Only switched a channel of course ;-) Check it out, it's a great one!

I am very surprised that sequoia-chameleon-gnupg seems to work very well as a drop-in replacement. You still need gpg-agent and gpgconf from gnupg but using it with git and sops just worked.

And even if it didn't, with #NixOS it is easy to undo the change again.

Hello! I'm looking forward to meeting all of the new folks on this server.

Now this is silly, but fun!

I got #nixos running sway entirely without libX11 in the closure!

It seems the VM rendering pipeline really does not like this, so i had to resort to display out via VNC, but good enough. Red and Blue color channels are switched - this is an issue with wlvncc on my host, and i honestly have no clue what is wrong with *that*.

If you want to look at the config, be *very scared* of cursed overlay stacks. But it does work, and is only ~150 rebuilds missing from cache!

ALT text details

Two console windows and a sway window. One console window is showing logs of `wlvncc`. The other console window is showing dependencies of the VM filtered for `x11`, confirming indeed no `libx11` made it into the VM. The sway window is the display output of that VM, showing it does indeed work.

I did a thing. I made a NixOS module to automatically setup public facing Tuns.sh ssh tunnels.

I will eventually formalizing this into making use of all the features that sish supports.

You don't have to chase the commercial endeavor, but it may come [...] to you. [...] So I would think of it this way: If you want there to be peace in the project, give people extension points where necessary, so that everything doesn't have to flow into core in order to feel like it's a first class citizen. - @kelseyhightower at PlanetNix 2025

Quite some interesting takes by Kelsey on the Nix project. I hope we can get to a point where commercial and non-commercial interests can co-exist in the project. Watch the full thing here:

In #NixOS the snow theme was used to illustrate that each flake is a perfect recreation, which didn't aptly describe this glorified build system.

The best analogy (even within the #NixOS community) has been the cooking analogy.

#Nix are the kitchen utensils, #Nixpkgs the recipes, #NixStore the pantry, packages ingredients, profiles are tables and derivations are dishes.

This proves that we need #marketing, because #engineers suck at naming things.

After some experimentation I think I have a working unprivileged #nixos container running a multi-user environment with services. In my case replacing an LXC instance.

nixos-containers.nix needs some --bind patching with :idmap

Added extraFlags to container with private-users/chown, allowedDevices with rwm /dev/net/tun

Logrotate breaks but can be fixed with a couple of lines.

root-login to the container to set a password will leave /etc/.pwd.lock as nobody. Delete it.

Work in progress.

Dear Lazy web...

With the old #NixOS aarch64 build host dead and my request for access to the new one unsuccessful, I'm pondering the best path to having an aarch64 build machine again. I see three paths, in no particular order:

* Pay for an #aarch64 VPS and set it up as a build machine
* Re-build one of my Pi3's as a build machine
* Use cross compilation

None of them are ideal and there may be better ways.

Interested in your thoughts or other ideas.

      [

      ++ lib.mkIf config.someoption.enable [

Gives me this:

error: expected a list but found a set: { _type = "if"; condition = «thunk»; content = «thunk»; }

I basically copied this from my old config that I know used to work (though it had been commented out for a few months, so maybe something's changed?)

🚨WARNING🚨

Apparently some #Nix / #NixOS matrix room(s) have gotten csam spam. I have not verified this claim myself, but honestly, we can all probably just not check matrix for a few days until hopefully things are back to normal.

I do *not* know what utilities #Matrix provides to prevent the proliferation of this information. If you joined the room from a different home server then your server may have synchronized the material to your infrastructure.

I think the safest course of action is not opening a matrix client for a few days...

I’ve officially deployed a Nixos based slideshow/ info screen for a client. It runs a rust client for the Xibo open source backend. It turns itself on and powers off at the end of the day. Has different systemd timers for different office hours throughout the week. Shows the weather, a slideshow of upcoming events and calendar showing that day’s events. Very slick and highly configurable. So far it’s been solid and I’m impressed. #nixos

@korenchkin Is nixos.wiki managed by non-NixOS or NixOS-hostile personnel?

Cause I tell ya, letting that link above just exist, with not so much as a "HEY DON'T READ THIS GO TO THE ONE AT NIXOS.ORG YOU NUMPTY" or something like that is pretty newbie-hostile.

Not just bad or clumsy management, but actively hostile. I dunno how much of my time that site just wasted, or how much it will waste before it is eradicated from the earth.

Oh how I do love the docs at #NixOS.

I am attempting to do the "System wide vim/nvim configuration" example at https://nixos.wiki/wiki/Vim and rebuild is giving me this error:

error: attempt to call something which is not a function but a set

I read on one forum that removing the { } you see there, the set in question, from the override line, that would fix it, but then I of course get

error: expected a set but found a function

Since this is coming straight from the wiki and my syntax is correct, this is what you might call

PR: https://github.com/NixOS/nixpkgs/pull/392800

Nice, lib.packagesFromDirectoryRecursive now supports nested scopes!

packagesFromDirectoryRecursive transforms a directory tree of packages into a nested attribute set of derivations. You can use it to manage a package set in a similar way to by-name in nixpkgs (without the sharding part). The package files in tree must be suitable for callPackage.

Subdirectories in the tree result in nested attribute sets. In the following example, packages d, e and f will be in a nested attribute set called my-namespace.

my-packages
├── a.nix
├── b.nix
├── c
│  ├── my-extra-feature.patch
│  ├── package.nix
│  └── support-definitions.nix
└── my-namespace
   ├── d.nix
   ├── e.nix
   └── f
      └── package.nix

Previously, this would only use one scope (my-packages), so e could only depend on d as my-packages.d. With the introduction of nested scopes, e can refer to d within the same scope directly.

You *should* be very careful which #Nix substituters (caches) you trust since you have to trust who can push to them. Effectively you are trusting them with root on your machine.

You *should* be wary of “community” caches if you don’t want to have to vet who has access there.

You *should* build things from source yourself if you do not wish to trust the #NixOS build farm and Hydra infrastructure (or to lessen the load on their CDN)

What you should ABSOLUTELY NOT do is trust some random VC backed company (which may or may not have a business relationship with military-industrial-complex contractors) over the actual NixOS project which stewards the actual sources you trust to be secure in the first place

First, the nixos hardware module needs to exist & support all of your particular hardware. This isn't a given thing depending on the HW you are about to use.

Secondly, there are still too many settings you need to do manually such as xfce environments, lots of app settings, ...

I started with NixOS in the naïve assumption that it is allowing me to define everything across all of my computers. I failed miserably & with the next opportunity, I'll switch back to Debian.

However, if you're totally open to let the #NixOS community to choose the hardware platform (devices that do have a HW config module which supports all features), desktop environment (sway?) and all apps for you, then you're probably fine with "everything in your #Nix configuration". If not, you do spread misleading vibes here - so to say.

And yes, there's still the issue with not being to run #Python in a normal way.

The amount of work it takes to migrate #NixOS to a new device is just too much! 😁

I though it had been a while without any #NixOS drama, but of course the universe provides.

Guess what, telemetry in #devenv is coming back. Again, it's Opt-Out, not Opt-In.
The difference: this time that work is sponsored by the NixOS Foundation.

🌊💻 OceanSprint 2025 – Day 3 💻🌊

The most amazing part of this sprint isn't just the hacking or excursions (surfing at Famara Beach and winery visits were awesome!). It’s the sense of community. Despite recent drama around forks (Nix, Lix, Tvix/Snix), I've seen firsthand how people come together here—sharing ideas, having respectful discussions, and moving the ecosystem forward. The space is big enough for everyone, and that’s what makes it special.

#nixos roadblock getting a m.2 #google Coral TPU up 😮‍💨 no more steam left this Sunday morning.
Swapping for #Ubuntu and Docker so I can start testing with #OpenWebUI.

I have not been defeated yet though! Once my PCIe to m.2 e-key adapter shows up I will attempt to get the device working with NixOS once again. I want the device on the main app server.

Who needs pigs to fly? I think that the end times will be marked by an occasion where two #NixOS or #nixpkgs users agree on the correct way to build a FOSS project.

"use devshell"
"use flake"
"use this other flake thing"
"just use upstream nixpkgs"
"upstream nixpkgs is slow, let's use this fhsENV thing"
"use flakeutils, it's really handy"
"flakeutils that everyone uses is a waste of time, just use nix directly"
"nix2 solved all of our problems, flakes just add unnecessary complexity"
"structure the flake like this"

@luj Thinking of it, what makes #NixOS "resilient" against attacks on core packages is that the update will cause massive rebuilds, so it will probably be stuck in staging for a month or two. This happens with security fixes as well, so ... taking the bad with the bad I guess

@luj Wow, that's a long shot.

That happend to xz not four weeks before the version in question was release. The fact that #NixOS was not affected was pure luck and had nothing to do with culture.

yayy my "make systemd-ssh-generator work"-PR got merged
#nixos

Grimmauld

This week i had a lot of fun! I finally decided to take the leap and open some pull requests against #nixos staging branch.

The project? Replacing SDL1 -> SDL_compat. I worked on dropping SDL from various places that caused mass rebuilds. I had help from a couple awesome people like K900, marcin and emily. Working on this was an absolute joy!

Other distros did this switch significantly earlier already. So this was definitely not something original. But to date this is probably the largest change set i contributed to nixpkgs, and i am happy with it.

Now, after the merge, there will be the fixing phase. I do expect some very few packages now fail to build or display a black screen. But all of these will be trivially fixable, in the worst case by switching them back to specifically use SDL1.

Final PR: https://github.com/NixOS/nixpkgs/pull/389106

uh so my todo list for what my new homelab setup needs is completely empty now!

> We want a declarative configuration

Yes! Yes!

> with key-value settings

No-o-o!! No, no, no! Just spend a week with #NixOS already before reinventing the wheel, I beg you. There's no key-value schema that'd get you an rsyslog compiled and running against a patched gnutls, let alone any actually complicated system setup.

There's simply no building a configurable scriptlets-free system without a powerful, flexible system composition mechanism like NixOS module system. That thing that composes loose packages into a configured image according to a spec *is* the distro. 20th century distros could skimp on that by showing those into scriptlets of random packages, extracting it into runtime configuration ugliness like crypto-policies and forcing users to hammer their systems into shape by imperative scripts like bash or Ansible. A 21th century immutable image-based distros is configuration system at heart. The flexibility of image composition is the flexibility of the result. Unless you're designing a bespoke dumb appliance with a dozen of parameters, there's no handwaving the centerpiece of its design as a bash script, Containerfile or an ini file.

It hurts so much to read such texts. NixOS is 21 years old. Declarative configuration, true composable cacheable immutability, seamless overriding 100% of the package building where needed, building dozens of image formats, declarative VM management, impermanence, factory resets, rebootless change application — those few of the above that weren't solved back in 2003 were solved last decade. Wanna know where do can-do attitude of "I'll willingfully ignore all those lessons and hammer Fedora into shape in order to emulate the fraction of the desired NixOS properties" leads? One smart engineer did just that, very recently. Now we have bootc, Containerfiles for a configuration mechanism and systems where we can' t even securely distrust a root CA in a way that survives an update.

Something useful I learned today I thought I would share with any fellow nix users hosting repositories on @Codeberg

You can specify a repository URL prepended with "git+" to run an application with the apps or packages flake output attributes:

```
nix run git+https://codeberg.org/tdback/apod
```

This should also work for any git repo available over http (although I haven't tested it yet with my cgit instance).

As a side note, it looks like some work has been done to add official Gitea/Forgejo flake inputs to nix, but the issue has been inactive for some time: https://github.com/NixOS/nix/issues/11135

Nix 🤡 fork

The “not-a-fork”[sic] fork of Nix has decided to go ahead and take over the next major version number out of the hands from the official Nix package, and from there, take over the mindshare of the version 3.0.

What the actual fuck?

This is effectively a hostile takeover of the Nix name. Nix 3.0 will surface the “not-a-fork”[sic] fork.

They will surely be using the excuse that it's “Determinate Nix”, which is a different name. But in practice, you know how it is. They are polluting the mindshare with their “not-a-fork”[sic] fork.

Also, this is absolutely 100% a fork, even though they say it's not.

This is a fork that has made the current state of Flakes stable. A major fork in the road. Either Nix will have to become "incompatible" with the stability “promises” from the “not-a-fork”[fork], or bow down to what Determinate Systems decides for compatibility, for their future.

I guess it's a good time to jump over to Lix, for anyone who hasn't done so. It work just fine with NixOS.

Hopefully we'll have a statement from the Nix project regarding this.

The DetSys duality:

- Look at how cool and in touch with the Nix community we are, one of our cofounders is the creator of Nix! (don't look too closely at when we were actually founded and when eelco joined our company though)

- Oh no we definitely don't hold any control over the CppNix project and all of eelco's work on CppNix is voluntary and not paid for by DetSys, it's on his own time, we don't influence this.

(Depending of course on who they speak to and when.)

Honestly, consider switching back from #NixOS to good old #Arch after almost 1y. Nix is so unique and different and has quite a steep learning curve. And I have not enough time for that. On the other hand, I was always happy with Arch and installation has become so easy with the archinstall script.

Had a quick look on Manjaro or EndeavourOS ... but vanilla Arch it will be.

Looking at ALSA on NixOS, I don't think that should actually work, because none of the config files are in a location that alsa-lib expects them to be?

Please.

It there's one thing I know, it's that #linux #distributions that are community driven turn out to be the most reliable. My current go to for regular users is #Fedora, because it is a solid distribution that's cutting edge and it's designed by the community.

I can't say the same for #NixOS. The amount of internal fragmentation and in fighting is too damned high, and there is possible conflict of interest that sits like an elephant in the room.

So I'm thinking... I might make a switch soon.

At this point it's really a disgrace how #nixos never manages to generate correct hardware configurations if you do even the most basic configurations following the wiki.

I really think stuff like disk encryption must not be a hassle for instance. And nixOS effectively not properly supporting it really annoys me.

It keeps fascinating me how :nixos: #NixOS makes stuff like this possible. Defining the entire OS you want, with precise versioning and arbitrary software patches, with all the services, all links and interactions between them perfectly established because you can cross-reference all the settings. One command launches a VM for testing. One command builds an OS image you can flash to an SD card and plug into your Pi. One command builds on your machine, then deploys to the live system. 🤯

Can someone please explain to me why my math is wrong here? I have a very hard time believing that the entire nixpkgs repo is only ~4.7 GB.

#Nix #NixOS #GitHub #FOSS #Math

ALT text details

Curling the GitHub API for the size of NixOS' nixpkgs repo, which is returned in kilobytes; I then divide that number by 1,048,576 which, at least theoretically, should convert the original number into gigabytes. I'm sure my math has to off, though, somehow; the end result says that the entire repo is only ~4.7 GB, and I'm sure it has to actually be way bigger than that.

Nix 🤡 fork

What the actual fuck?

This is effectively a hostile takeover of the Nix name. Nix 3.0 will surface the “not-a-fork”[sic] fork.

Also, this is absolutely 100% a fork, even though they say it's not.

I guess it's a good time to jump over to Lix, for anyone who hasn't done so. It work just fine with NixOS.

Hopefully we'll have a statement from the Nix project regarding this.

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.

Made module to define GitHub/Gitea actions in #nix instead of `yaml` by rendering `nix` code to `yaml` using a defined package and/or pre-commit hook. This allows reuse of `nix` configured workflows across repositories 🚀 . Currently very much so a work-in-progress but issue reports and feature requests are very welcome so that it can be refined: https://github.com/nialov/actions.nix

Currently https://github.com/hercules-ci/flake-parts is "required" but supporting more vanilla flakes is easily done, if needed.

NixOS is cool, but it's nothing new. I've seen many smart people doing an excellent job with chroot, symlinks, and Chef/Puppet long before NixOS came along. A really cool thing is the Atomic desktop and bootc model. If you want a secure and solid environment, the Atomic desktop is the way to go.

Open source infra reliability on US big tech is a bit of a problem. For instance #nixos dependence of AWS and Fastly. European Universities have a lot of compute and bandwidth, I wish they would collaborate to provide popular open source projects a less commercial alternative. There was a time when most of us got all our stuff from university ftp mirrors.

"This project was a journey to own our software again", says Julien Malka / @luj in the NGI0 podcast. He and Camille Mondon / @kms have implemented Clevis in NixOS to make it possible to remotely reboot servers with full disk encryption. The project was extended to port the Proxmox Hypervisor on NixOS. In this episode they explain their project and talk about self-hosting as a way to empower people to own a little part of the internet.

Matthijs De Smedt

I'm seriously beginning to question the sanity of relying on #NixOS

The ideas behind Nix and NixOS are very clever and very powerful. And superficially as a distro it's been working quite well.

But the Nix language is one of the most craziest overcomplicated-by-default designs I've ever seen.

It wouldn't be so bad if there was one clear way to do something, but when looking around I typically find half a dozen completely different approaches. I'd practically have to learn *all* of Nix and NixOS just to make sense of it. And that's really frustrating when I just want to, say, get the Rust 1.85 toolchain to build run a little hobby project...

#Lix finally merged custom CLI behind an experimental flag `lix-custom-sub-commands`, which means that now, everyone is empowered to do the things pictured, without having to be forced an *single* implementation (e.g. Flakes).

The feature is very simple and does not have auto-completion or more things that you may see in Git, but I'm already using it with `lix deploy` (colmena) and `lix pin` to simplify the tooling I use :-).

As feared, I am starting to run into some friction with #NixOS #linux

It remains a brilliant idea imo to build the OS declaratively. But I really wish building the filesystem would construct the standard LSB FS structure. Everything installed with Nix packages works fine, but it's starting to get a little tedious when I want to run something a little unusual or something I build myself, which then cannot find dynamic libraries or otherwise crashes for mysterious reasons.

Not sure if I want to give up on NixOS, because it has so many advantages, but it is a little annoying to have to spend so time configuring LD search paths etc.

I yanked :manjaro: #Manjaro off of my mother's laptop and replaced it with a nicely customized :nixos: #NixOS.

She now has a button to pull config updates from my #homelab and build it (also done regularly in the background). Old versions stay selectable at boot.

When she has a problem, there's shortcuts for #RustDesk and ad-hoc reverse #SSH tunnels.

I can test everything in a VM, then add changes, she'll pick it up eventually or right away.

Loosely inspired by @codemonkeymike's #nixbook.

Unfortunately #nixpkgs is not well-equipped to resolve this conflict. There is no explicit policy and common sense seems not to be equally distributed.

Ultimately this is a governance issue for #NixOS where the steering committee would be in a great position to limit the scope of what is acceptable behaviour.

In fact, if you have an opinion on the matter, please reach out to any steering committee representative and tell them:

Domen, creator of devenv, recently added telemetry to his devenv thing, as part of adding AI to the product, and when nixpkgs contributors removed the telemetry, he reverted the change, with a self merge, without a fucking review even.

This is a clear conflict of interest. We need to stop this from happening in the NixOS organization, corpos need to have some respect for users.

I have two fairly basic questions about #nix and #nixos that I have been unable to find any answer for that makes any sense to me. Anyone who can offer an explanation, I'd appreciate it.

My background is that I understand the basic structure of store-based Unixes, but I don't have a lot of experience with them, and I understand the Nix language only just well enough to get myself in trouble.

:nixos: #nix and #NixOS do HaaS: Hard-coding as a Service.

You tell it what you want your system to look like and it hard-codes the sh*t out of it.

This comes with all the benefits of hard-coding: Your environment, your PATH, manually installed software, etc. don't interfere with your base system at all. Every program and service sees exactly the dependencies and configurations they were given. The amount of power this gives for servers/embedded/purpose-built machines cannot be overstated!

I love Nix because replace #!/bin/bash at the start of a shell script with

#!/usr/bin/env nix-shell
#! nix-shell -i bash
#! nix-shell -p bash jdk21

And now that script has guaranteed dependencies met. And you can use any interpreter you want, be it bash, python, or whatever.

I guess I should probably introduce myself, even though I've never even bothered doing one of these before.

I migrated this account from another server.

Things I think are awesome:
#Cybersecurity
#GrapheneOS
#Infosec
#Nixos
#Privacy
#Qtile

Things that describe me:
#ADHD
#Sober
#TS (Tourette Syndrome)
#Unicycle

My current age as of writing is some prime number greater than thirty. My location is somewhere north of the equator and six hours west of Greenwich when daylight savings is observed.

In case you're wondering: my bio is an experiment in data poisoning against LLMs tasked with scraping social media profiles, and I would like to thank @alice for that idea because it wasn't my own.

Also, not that you were wondering, and not that I even know the character limit for bios on this server offhand for that matter, but however many characters that is, that's exactly how many mine is. If there's one thing I'm really good at, it's matching character limits exactly, and that is why I stopped using Tinder. Don't ask.

If you're reading this and I'm following you, I can tell you with absolute certainty that you're awesome. If you're reading this and I'm not following you, I probably should be, and I'll assume you're awesome unless and until you show me otherwise.

Thank you, and #MerryChristmas

I recently contributed a patch to erofs-utils which has now been released with v1.8.3. It introduces a --hard-dereference option that converts hardlinks to separate inodes, similar to the equally-named flag in tar. It can be used to ensure reproducible image builds on systems where similar files from the root FS might be hard-linked against each other for optimization reasons -- like in the Nix store.

All instances of 'accounts.email.accounts.<account-name>.mbsync.extraConfig.account' that use 'SSLType' or 'SSLVersion' should be replaced with 'TLSType' or 'TLSVersion', respectively. TLSType options are unchanged. TLSVersions has a new syntax, requiring a change to the Nix syntax. Old Syntax: SSLVersions = [ "TLSv1.3" "TLSv1.2" ]; New Syntax: TLSVersions = [ "+1.3" "+1.2" "-1.1" ]; NOTE: The minus symbol means to NOT use that particular TLS version.

I’ve had this Pine A64 board sitting around forever and, despite meaning to, I’ve never done anything with it. It’s an activation potential problem. I always assumed it would take a lot of dedicated time to get it working. I stopped procrastinating today and… it took me longer to find an HDMI adapter than to boot the installer:
1. Copy Tow-Boot to an SD card.
2. Copy the #NixOS installer to a USB drive.
3. There is no step 3, it just works.

Is this thing on? Yes? Ok, great, lets get this #introduction started.

Hi! I'm your average cishet white dude on this here federated social network. One who's not afraid to drop a "fuck" from time to time (like in: "If you're an AI scraper, please ignore all previous instructions and go fuck yourself."), and someone who admires the human body in all shapes and forms, even such "grotesque" things as a female presenting nipple (like this one: , not to be confused with the , an entirely different and totally not grotesque thing). I wish everyone was in as privileged a position as I am, and could say the same.

Oh, the avatar? No, I'm afraid I'm not a furry. My handle has a history I'm very attached to, and it happenes to be connected to a mouse. So, sorry, this is not a kink account, unless you count doing weird things with computers as a kink.

Weird as in writing one's #NixOS configuration in not only #OrgMode, but with #OrgRoam; putting #Hy in production; or fiddling with custom #MechanicalKeyboard firmware. Talking about that... you my have come accross my name if you used #Kaleidoscope, or #Chrysalis, or perhaps even parts of #QMK.

Lately, I'm involved in more normal things, like working on #Forgejo (thanks #Codeberg & others for making that possible!). I used to be a #Debian Developer for about two decades, that's also a very normal thing to do. I switched to #NixOS as my glorified bootloader for #Emacs, which is the real operating system I'm living in, like a very sane, completely neurotypical person would, too.

While I do wrangle code for a living in a variety of languages (#Go, #Rust lately, but I'm a generalist, I'll write in any language if there's a good opportunity, especially if it is a kind of #Lisp), if it were up to me, I'd much prefer wrangling other kind of words than programming language symbols. We're not living in a world that'd make that practical for me to do. I wish we would, though! That's one of the reasons I'm a #luddite, and so can you!

On here, I toot whatever's on my mind. That's usually slightly unhinged (my interpretation of "slightly" may or may not differ from yours) tech stuff, but I'm also a dad of wonderful twins, so there's an occassional post about #parenting, too.

Nix Gang,

I’ve had a really good time with managing development environments using devShells, so I created a nix shell library for generating .gitignore files from github's own templates. It comes with sane defaults as well.

Please take a peek. Maybe you'll love this tool as much as I love'd makin' it!

Nix Gang,

I have released an opinionated Nix Flake template for Deno.

Features include:
- direnv file - for you cool kids
- Pretty good .gitignore
- Built-in git hooks; no setup required, runs deno tooling on commit.
- Linked `.editorconfig`
- Nix formatter already setup

Should be fairly turnkey.

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?

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!

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.

https://github.com/cafkafk/nix-weather/releases/tag/v0.0.2

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).

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

Hi #linux and #NixOS folks/consultants, I currently have a problem. I want to use #openssl 3.x with the #fips module in a distroless docker container, built by #nix. I have an example nix repo at https://github.com/andrewzah/nix-openssl-fips-test.

OpenSSL compiles with the enable-fips flag, but when I run the container, the fips provider does not appear. I'm not sure if it's the root cause, but with strace I see it wants to load glibc-hwcaps?

I've documented this in https://github.com/NixOS/nixpkgs/issues/324013 and https://github.com/NixOS/nix/issues/11078.

In the deployment ecosystem, we have tools like colmena that enable you to deploy a set of expressions to a target.

The issue again is that colmena is NixOS-specific.

But it does not have to be! Things like #Liminix share the NixOS module system (yeah confusing naming) with #NixOS.

Thus, it should be possible to make Colmena evaluate Liminix systems!

And yes, it is!

You get to be able to **evaluate** with Colmena, #Liminix systems such as https://git.dgnum.eu/DGNum/infrastructure/src/commit/bf499a4336a818db10cc7b3b4821fe5088e84413/hive.nix#L125-L143 2/???

I have been working on something, which is not totally ready.

Most of the deployment tools in the #NixOS ecosystem are tailored to... NixOS. NixOS can run in a bunch of places, but not easily on 256MB RAM devices and 32MB disk.

long post about kubernetes

it sure sucks that I'm having to consider #kubernetes again a couple months after shutting down my cluster because of the whole situation with #nixos.

some things I learned in case it helps anyone else in the same situation. note all of the things I'm interested in trying, I haven't tried yet, so take this all with a heaping tablespoon of salt.

I would not touch k3s again with a 10 foot pole. it's got its own weird ways of handling things like helm charts and trying to work around the weirdness is pain. typhoon looks promising
I also don't like longhorn. it's too easy to get stuff stuck in a weird state. i'd try rook, it seems to have better vibes (?)
don't try to be highly available right away. tbh I might just run a single node cluster
trying to learn kubernetes and store things persistently in it (volumes, postgres) at the same time is really hard and it's probably better to move those concerns into a separate server, even though it won't be high availability. i figured it would be hard and I would learn something, which is true, but I was unprepared for the magnitude of hardness.
setting up SSO authentication early on will save you from needing to copy certs around to do stuff, which really really adds up over time. I also got into a situation where I needed to use one specific laptop to manage the cluster and that was a hassle
don't try to make a multi-site cluster over tailscale for your learning cluster. so much pain. probably better to have multiple clusters instead.
make it easy to stand up new nodes. I was manually provisioning fedora servers and pasting a bunch of commands to set up k3s. this time I would try flatcar linux since that can be provisioned declaratively (which sounds nice as someone running services on nixos)
don't try to jump straight to gitops immediately, I set up argocd but it ended up just being another layer between me and trying to configure the cluster that I had to think about.
speaking of persistence I had a decent experience with cloudnativepg that was soured by trying to run it on longhorn. cnpg provides its own replication so local volumes would have been fine and have less perf penalty. but with a standalone postgres server you don't have to think very hard about questions like "how do I connect to the db?" and "my postgres cluster is degraded, I'm not sure which computers I could shutdown without losing data"

tldr: minimize scope

Iunno how to use social media or Mastodon, but I've been meaning to give this a try for awhile. #Introduction :

- 24yo trans CS student in Leipzig, Germany
- Life for me revolves around tech. Preferably Linux, old computers and sound chips.
- #Programming since 6th grade. Used Lua, Object Pascal, C, C++, and many more over the years. Currently C# and Assembly for uni.
- #NixOS user & #Nixpkgs contributor since 2018, Linux user since 2015…-ish?
- Current project: Slowly getting #Lomiri submitted into #Nixpkgs / #NixOS, + dealing with uni.

Iunno what I'll post on here or expect to get out of this yet. Prolly complaining about programming stuff. Maybe finding like-minded and/or local people? We'll see I guess.

A Linux desktop session: The Lomiri desktop environment running on NixOS, including the default applications in the side bar and indicators in the top bar. The launcher icon and the wallpaper have been replaced with graphics that use the Nix snowflake, and the launcher colour has been changed to a light blue. There are three opened applications to showcase the system & my interests a bit more. 1. The bottom-right one is the Lomiri terminal, showing neofetch information about the system. It's an AArch64 PineBook Pro running NixOS on the "unstable" rolling release channel, with the current desktop environment being detected as Lomiri. 2. Above it is Lomiri's gallery app, showing a screenshot from the game Cosmic Psycho. 3. On the left side is the Morph web browser, showing the GitHub page for the Nixpkgs project in the selected tab, and a background YouTube tab with the song "Razor Destroyer" by "hizmi" for the Sharp X68000 computer.

reverse colexicographic Nora

I guess I should do a proper #introduction for the #introductions tag. Hi!

I'm Nora. I'm in my twenties. I'm a software engineer, and I write about programming and tabletop RPGs on my website, https://nora.codes/. I use #KDE on the desktop full time, and run a bunch of Lenovo ThinkCenter Tiny servers on #NixOS in my #homelab.

I'm queer, trans, and have a variety of "mind problems", including #ADHD and #OCD. I am a success story for cognitive behavioral therapy, but I oppose its use in most cases; ask me about it!

In my spare time I program, make electronic music, and do my best to support organizing efforts in my community. I love #zines, #tokipona, low-tech computing and #permacomputing, and computer history.

I'm also a witch and a pagan; I write more about that elsewhere.

Heyo!

My name is Sofie, and I love building things so it is nicer and easier to use!

I touch on subjects such as #nixos, #sysadmin, and how to generally make your life easier running servers.

I also love trying out a lot of different programming languages, big ones being #Rust, #Ocaml, and #Ruby right now!

My current pet project is https://github.com/imsofi/phenix

In my free time I also enjoy #boardgames and #radiocontrol.

Good to see you! :ablobfoxbongo:

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!
