my #lixcon2026 talk about build system yuri has been released: https://media.ccc.de/v/lixcon-2026-2-nix-and-buck2-from-enemies-to-lovers-with-snowydeer

slides: https://jade.fyi/lixcon2026

we build #nix store paths entirely outside of nix using deps from nix, then re-import them (with correct deps!) into nix once built. this powers writing a docker image in 6 lines of code without devs touching nix language at all.

you can use a new parameter in #lix 2.95's CLI to import store paths built by other build systems like we're doing, using `nix store add-path --references-list-json`.
happy yuri!

« Fake supply chain security, even worse than no supply chain security at all? »

Indeed, it’s a question for #Nix and #Guix. Yeah 1. … and then 2. …

2/6

A simple analogy for anyone to understand how #nix is different from tools like #ansible etc

Ansible(convergent) is like carving a wood, where u have some existing state like plain wood which u tinker continuously until u achieve the expected state

Nix(congruent) is like 3d printing, where the exact expected state is created from the start🔥

[lien] cloud-gouv/securix: Sécurix is a NixOS-based secure operating system tailored for small to medium-sized teams. It provides a minimal, hardened environment with strong isolation, reproducibility, and policy-driven configurations to ensure operational security and compliance. #security #gik #nix

@gaby_wald So the french government is making a distro based on #nixos.
Let's gooo!
The future is #nix !!

Meh, managing eval-time "secrets" in #Nix – as in not-so-public information like additional home-manager SSH config entries – is still a bit of a mess. While sops-nix is good for managing actual secret *files* at activation and runtime, looks like I still need to keep my additional non-public repo with personal data for these eval-time items. :\

@vivekanandanks Great, we need more good #nix content out there. Youtube is overrun by AI slop (and it's ridiculously hard on the webapp to ignore such channels). I'm on https://tube.tchncs.de for my videos.

My plan so far are
1) standalone content creation,
2) casual community online meet,
3) a regular online workshop like thing

So please suggest more such formats and also some platforms/ instances if possible
#nix #nixos #video #contentcreation

Hi All
Though too much procrastination, I'm again feeling like to start a video content creations in peertube, odysee, youtube etc
The contents would be on nix for beginners.
These days I see more content creations than last year for nix, but still nix is something many misunderstand as hard to begin with. I plan to ease the initial friction.

Ant tips/suggestions for the platforms are welcome preferably open source ones

We're happy to announce #Lix 2.95 "Kakigōri" is now available.

This version brings a wide range of improvements, including numerous bug fixes, reduced technical debt, and quality-of-life enhancements. You'll also notice better performance when working with certain large dependency graphs. Flakes and RPC are still key areas we are working on.

For the full list of changes, check out our blog post!

#Nix #NixOS

#nix #linux 👍🏻

@tux Nein, das wird nur der #nix Paketmanager sein. Aber das öffnet die Tür zu #homeManager, also einem "Mini-NixOS" nur für den User. Da kann man auch schon einiges mit erreichen.

#Nix Paketmanager kommt für #Fedora 😯

Hat das Teil den selben Funktionsumfang wie bei #NixOs ?

z.b. User anlegen, Firewall steuern usw?

Guix System - One Month Later https://lobste.rs/s/koymkj #lisp #nix
https://nemin.hu/guix-one-month-later.html

Wrote my first #Rust program today. A small utility to grab the last value of a matching column in a matching csv file. I had hacked something together with #qsv, #nushell and #python, but those were all too slow for fast repeated calls. This Rust version executes 10-100x faster: a few ms on a #RaspberryPi 4, neat! 👌

Rust and #nix is also a match made in heaven, omg is the experience better than Python 🫠

$ csvget scd30 co2
940.66

TIL that in #nix, "${./mydir}" will survive a garbage collection, but a plain ./mydir will not!

Took me way too long to figure this out. Didn't help that `just` gives a stupid error message about a missing shell when it can't change into its -d working directory. 🤦

And here is my published dissertation @umphy, about quantifying the natural CO2 exhaust at the Starzach site in Southwest Germany (my result: ~10t/d):

I used a lot of #FOSS software and hardware for all of it and it was amazing. Honorable mentions: #gitAnnex, #dataLad, #KiCAD, #OpenSCAD, #PlatformIO, #Arduino, #TexLaTeX. I just wish I'd used #nix / #nixOS sooner.

Figure 9: Flux-gradient setup close to the ground, next to the Starzach site’s mofette with the largest diameter (30 cm, Figure 2b, examined in 2015 by Lübben and Leven, 2022). Four Sensirion SCD30 low-cost CO2 sensors each are mounted 40 cm above and below a Campbell Scientific IRGASON eddy covariance station at 60 cm height. Measurements of this setup are shown in Figure 10 and Figure 11.

Anyone else thinking that automatic installation of #git hooks via `nix develop` is invasive?
