chatgpt (just good old sol for now 👀) found @flox.dev. this looks promising. i was thinking that they should make nix that is easy to understand and, well, they did it. (though i haven't tried it yet.)

#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.

#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. ❤️

You can't afford "works on my machine" friction across humans, agents, local dev and production workflows. @resolveai.bsky.social is one of the most exciting AI companies building right now, and I'm proud @flox.dev is part of their foundation. (#magics of #nixos)

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!

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!
