Nix / NixOS

cross-posted from: https://pawb.social/post/6260688

Recently, I switched to NixOS and realised that there is no G'MIC plugin package for Krita.

There's this issue that was last active in October 2023.

I was wondering if anyone has managed to install this without using another package manager (such as Flatpak) or installing an AppImage manually, for system reproducibility, and I also don't wanna have two package managers in one system.

Ideally, there'd be a wrapper, so you could do something like:

{ pkgs, ... }: {
  programs.krita = {
    enable = true;
    gmic.enable = true;
    gmic.package = pkgs.krita.gmic-qt;
  };
}

Thoughts?

Related: is there some kind of guide on these program.<name> wrappers? What are they and where are they defined?

I'm a semi-recent NixOS user and one thing that bothers me since the beginning is that when I change the Gnome theme (between light and dark), Firefox doesn't adapt. The system theme in Firefox is enabled, but it always displays the light theme, no matter what theme is selected in Gnome.

Internet search, including searching through NixOS discourse, packages, options and Nixpkgs repo surfaced a solution.

Any ideas or tips how to achieve system theme integration for Firefox on NixOS?

If all goes well, we can release the alpha by the end of March

Now Available on NixOS!

COSMIC Terminal joins a long list of COSMIC DE projects that have been packaged for NixOS! While COSMIC DE will be the flagship desktop for Pop!_OS, it's designed and architected for distros to build their own custom, branded user experiences. Details for distro packaging will be released at the same time as the alpha.

It's a WIP, but I hope it's understandable and contains the necessary information to start packaging something using the builtin derivation function.

Despite the name, the nixlang wiki is a community contributor wiki to document things around nix that the maintainers haven't gotten around to, to short-circuit the lengthy review process for the official documentation, and an attempt to make an entry into the nix ecosystem easier.

It's difficult to write things from a perspective of somebody who doesn't know, despite once being that person!

It would be great to have some feedback on the wiki.

P.S I'm not the maintainer, just a contributor.

🗓️ Mark your calendars! NixCon North America 2024 is happening on March 14th and 15th at the Pasadena Convention Center in Pasadena, CA, USA. Submit your talk or workshop proposal before December 31, 2023, 11:59 PM PST. Be a part of this exciting event! More details at: https://discourse.nixos.org/t/nixcon-na-2024-call-for-proposals/36491

A few months ago I went on a quest for a DNS server and was dissatisfied with current maintained projects. They were either good at adblocking (Blocky, grimd…) or good at specifying custom DNS (CoreDNS…).

So I forked grimd and embarked on rewriting a good chunk of it for it to address my needs - the result is leng.

• it is fast
• it is small
• it is easy
• you can specify blocklists and it will fetch them for you
• you can specify custom DNS records with proper zone file syntax (SRV records, etc)
• it supports DNS-over-HTTPS so you can stay private

I just released a new version which includes full NixOS support via a module! ❄

From this thread I found out about https://devenv.sh and https://www.jetpack.io/devbox but I'm having trouble comparing them to nix-shell.

Are they wrappers around nix-shell? They seem to do the same thing with services, devcontainer generation, environment variables, etc.

Hi all, looking for tutorials online is cool and all, but sometimes you just wanna sit down and read a physical book to understand something. So I was looking for suggestions on which books helped you the most, or which you've heard positive things about. Thanks!

A key thing to note:
"Updating with nixos-rebuild boot and rebooting is recommended, since in some rare cases the nixos-rebuild switch into the new generation on a live system might fail due to missing mount units."

Also I'm not sure if this is the beta release as Package Search currently(as of 3:22am) displays channel option: "23.11 Beta" (this might get updated soon who knows)

Other notable things that I've seen in the release notes:

• sudo-rs is now supported
• btrfs now can be auto resized
• NetworkManager now uses nftables backend unconditionally
• new service options for SearXNG "for better support"
• new option for QEMU for enabling "specifying explicitly named network interfaces in QEMU VMs"
• "virt-manager, an UI for managing virtual machines in libvirt, is now available as programs.virt-manager."
  • (this one's gonna be interesting for my config as I currently have it installed as a package, I'm gonna guess it's probably fine)
• fail2ban configuration with attribute sets
• "New boot.bcache.enable (default enabled) allows completely removing bcache mount support."

Either way I'd def recommend checking out their announcement and releases page for more details~
Thanks to the devs for making an awesone distro!🤗🎉

We are starting a new meetup group for the Rhein-Neckar-Region in Heidelberg, Germany.

The first event will take place on December 19 at the University's Mathematikon.

The twist is that we're beginning with a dual-topic meetup: Nix & Rust.

As there is some overlap between the two communities and we couldn't decide for which of the two we'd rather organize a meetup, we went for both in one.

The meetup is organized through the regional Mobilizon instance: https://rheinneckar.events/events/298e520c-89ca-4754-96f8-e252b96b7a46

Please sign up if you plan on attending so we can make sure there is enough space for all participants. Also feel free to drop an email at nixrust@rheinneckar.events or a Mastodon message at https://rheinneckar.social/@NixRust if you would like to become a speaker for the meetup, be it with a NixOS or Rust topic, or a combination of both!

The current (tentative) schedule:

• 18:30 - Open Doors

• 19:00 - Greeting

• 19:05 - An Introduction to Nix

• 19:30 - Second Talk (Rust related)

• 20:00 - Networking and get together

Someone on another website asked me whether it makes sense to use agenix or sops-nix to encrypt secrets for NixOS configurations.

I realized that I hadn't seen a good overview article of the different approaches to secret handling in NixOS and when each one is appropriate to use, so I put down all of my knowledge and opinions in this post 🤞

Sorry Noob here. This is my second time trying NixOS as a desktop. I just did a new installation of NixOS on my main pc.

In Arch my goto kernel was the Zen kernel. Is something similar available on NixOS ?

What kernels do you use / has got the most out of ?

I've made a fun little project inspired by this (except it's not updated any more).

It provides easy instructions for installing old versions of packages, it takes them straight from the official nixpkgs repo.

Example: https://history.nix-packages.com/package/dotnet-sdk_3/3.1.426 (.NET SDK 3.1 actually prompted the creation of this tool, I needed it for one old project).

Each detail page provides instructions on how to install the package using nix-shell, nix-shell with shell.nix file, configuration.nix and nix-env.

The design is based on https://search.nixos.org (because I suck at graphical design).

Do let me know what you think!

It currently requires some extra steps to get Nitter up and running on NixOS as I found out yesterday. I documented the process for anyone else who might be looking to run their own Nitter instance between now and the trunk branch of Nitter being functional again.
