Anyone interested to hack on Nix in Mexico? June 20 – 26 I have two free tickets: tacosprint.org

Looks like this is where we're heading

Time for the seasonal garbage collection.

Does Nix feel faster yet?

Last week I built a little tool to find hot paths in Nix evaluations, classify and find simplifications trough code mutation. Now nixpkgs eval is 30-50% faster on cross-compilation targets :-D Let me know if you have slow code. github.com/NixOS/nixpkg...

I'll be in SF March 7–11 after PlanetNix. Any builders around? DMs open.

The feeling that I could re-use code I wrote, is what got me hooked onto Nix. Chef, Puppet, and Ansible are at an unfair advantage. What makes Nix structurally different is the vertical integration between the OS and package manager.

With Nix, if you need any service or package not in search.nixos.org, go to github.com/search and search "language:Nix theservice". Most of the time, someone has already implemented it.

I love to see PRs like this. By defining a formatter spec, treefmt keeps its code simple, and slowly pushes the formatter ecosystem in the right direction. It works surprisingly well. github.com/reteps/docke...

When your auto-updater bot has more commits than you in your project :-p github.com/numtide/nix-...

Tired of hitting rate limits when running `nix flake update`? Trying to fetch a private repository in your flake inputs or builtin fetchers? Here is a new tool for you (still early, looking for feedback): github.com/numtide/nix-...

github.com/numtide/tree... now supports 100 formatters! :)

Something I have been working on for the past month. I'm excited to see what improved communication can bring to the NixOS ecosystem. discourse.nixos.org/t/introducin...

Prediction: one or more languages will emerge, optimised for LLMs to talk to each other. We'll start seeing Tweets that humans don't understand.

Our team is hiring. If Nix, NixOS and AWS sounds like fun check it out. grnh.se/7bba27744us

✨ devenv 1.4: Generating Nix Developer Environments Using AI devenv.sh/blog/2025/02...

excalidraw.com is great to have around when having technical conversations. I like how zero-friction it is.

Did anybody use www.citadel.org? Every few years I run into it, and it has this intriguing set of features and vibe. BBS for the Web. I'm curious if any businesses are using it.

FOSDEM gave me the cough'dem. suno.com/song/de2da7c...

Brian wrote a post on blueprint: bmcgee.ie/posts/2025/0... The project is coming along quite nicely.

Anybody else is going to FOSDEM this year? Created a room for the NixOS peeps: matrix.to#/%23nixos-fo...

My wife was happy with her Pixel 4a phone. Last week Google pushed a software update, and now the battery is draining like a sieve. Google doesn't explain why this happeend and how to fix this. news.ycombinator.com/item?id=4286...

Is anybody using determinate.systems/posts/magic-... ? Kinda wondering if it's worth rewriting it in TypeScript.

discourse.nixos.org/t/nix-2-26-r... Nix 2.26 is out! The biggest change is how path sub-flakes are handled. Previously, their input was locked by a hash which led to confusion from users. With that change, having a `./dev` sub-flake now becomes practical.

Lix has the most enjoyable release notes of the industry. It repeats what the project is about, has a great tone, provides a summary and details. Love it.

Can't believe we're 6 short of 100 supported code formatters already. github.com/numtide/tree...

Reminder that you can get unfree+redistributable binaries (eg: CUDA, ZeroTier or MongoDB) from the nix-community.cachix.org cache. I noticed today that this knowledge is not widely available. hydra.nix-community.org/project/nixp...

There. One less papercut. github.com/nix-communit...

Did you ever deploy your NixOS configuration to the wrong host? It happened to me a few times. Luckily it's easy to revert but it can cause downtime and state folders to be left around.

This direnv competitor looks great: github.com/jdx/mise

Christmas is for fixing papercuts. github.com/NixOS/nix/pu...

Can I get a "no American politics" filter? It would be good for my brain.

Was thinking about this again: zimbatm.com/notes/garnix...

For companies looking to give back, Oceansprint is great ROI in terms of amount of dollar spent to positive outcomes. * github.com/nix-communit... * github.com/NixOS/nixpkg... * noogle.dev * ... And so many human connections that contribute to a more healthy ecosystem.

We finished upstreaming nixos-generators project. Take existing NixOS configurations and generate images for all sort of targets: ``` nixos-rebuild build-image --flake .#my-system --image-variant digital-ocean ``` github.com/NixOS/nixpkg...

garnix.io is so good. It's suprising it's not the default CI for all new Nix projects.

Thinking about goals for 2025. What big changes would you like to see next year for #Nix and #NixOS?

Cool, Vulnix is maintained again! github.com/nix-communit...

Just got reminded of this. Can you guess what the return value will be? :) ``` $ nix repl nix-repl> 1/0 ```

Are you tired of downloading a full copy of nixpkgs for every project? Update your flake inputs to do this more incrementally: ```diff - nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable"; + nixpkgs.url = "git+https://github.com/NixOS/nixpkgs?shallow=1&ref=nixpkgs-unstable"; ```

The best NixOS release. I might be biased by the new Logo. discourse.nixos.org/t/nixos-24-1...

Archaeologists found an ancient tablet with these carvings: ᣏɨᰞ They say it depicts a prophecy.

NixOS meetup in Zurich. Comparing the deployment models between Clan, Thymis and Fediversity. All deploying NixOS, in different ways.

Bluesky, Tell me, What are you building?

Ok, Bluesky: nixos.tvix.store 😊

Hello, Is this where the real people went?
