#nixos is strong. Nearly 2B requests and almost 1 petabyte of bandwidth every week - the scale behind cache.nixos.org and releases.nixos.org. @awscloud.bsky.social is extending its support for the 4th year! discourse.nixos.org/t/aws-nixos-... Big ♥️ to AWS and the Nix Infra team. ❄️

Justin, David, and Alan just joined Flox. ❤️ The fun part right now is that the team is growing because the problems in front of us are getting bigger. Customers and users are pushing Flox deeper into security, enterprise, and AI. The world of @nixos.org keeps growing! (4 more roles open)

For anyone reading this and jumping to a broader conclusion: the Nixpkgs core team disbanding does not mean Nixpkgs or Nix is dying. It does mean that this particular structure was not sustainable, very important contributors burnt out and we need to do better, faster.

We need to continue learning from this and continue building a stronger ecosystem that prioritizes the contributors who are the only reason any of this is possible.

Personally, I'm sorry and grateful. Sorry that it ended in core folks being burnt out. Grateful since they did some of the most amazing work, more than anyone can imagine two people doing.

❄️ A lot of people want to contribute and do not know where to begin. 36% want to contribute now but do not know how to get started or join an existing effort. Another 35.8% plan to contribute in the future.

❄️ Nix is becoming a regular tool, but it still asks a lot from its users. 81.1% consider Nix part of their regular toolset. Only 4% say they understand every error message, while error messages and the reference manual remain near the top of the improvement list.

@temporaltech.bsky.social. @flox.dev. James Bayer. You don't need more ;) Join us next week as we go live on the Agentic Stack and AI Ready Environments with dashes of magic from Flox and Nix! #nixos + #ai = 🧠

Flox@flox.dev

We're going live with Temporal on June 24. James Bayer shows how a reproducible Temporal + AI dev environment goes from a stack of manual setup steps to one command: `flox activate`. Then more on sandboxing, security & observability. 📆 Jun 24 · 11am PT · buff.ly/8xH3pQu

#NixOS community bat signal 🦇 ❄️ @awscloud.bsky.social has sponsored the Nix S3 Cache for 3 years, and we’re working on what comes next. DM/comment if your company runs Nix/NixOS on AWS, or if Nix is used inside Amazon/AWS. Every example helps show the real Nix footprint. ❤️

Happy to say that I've been using Flox for a couple of weeks and so far (after some initial networking weirdness that wasn't Flox's fault) it's Just Worked. The rest of my team is still getting used to it, so it's possible we'll encounter new pain points in the future, but so far it's been great!

NixCon 2026 CFP is open! ❄️🔥 Time to stop telling your friends “someone should give a talk about that” and become the someone. I’m opening up my calendar to help workshop submissions. Brainstorming, tightening abstracts, etc. @nixos.org Drop a reply and we'll book a slot! 👇

600+ builders. @kelseyhightower.com & I. Tomorrow morning at #planetnix. We are tackling the main question: Why Nix, and why now? Because AI just 100x'd our abilities and speed but also the complexity of our software stack. Nix is the deterministic rails for the AI era.

Nix represents a different way of building reproducible software, but Nix has its own challenges, and in many ways Docker already won. So what hope is there for something like Nix in the long run? Come find out tomorrow at the @flox.dev virtual event.

I've been experimenting with @flox.dev for a project and its really nice! I've wanted to get into #nixos for a while and Flox simplifies Nix significantly. Next will be using it to replace homebrew for everything except casks. I'll probably also look to use it for a project at work. I'm sold!
