Improved evaluation times with pre-resolved Nix store paths Speed up Nix deployments, especially on resource-constrained devices, by avoiding the evaluation tax

Have you used FlakeHub's pre-evaluated store paths feature? Even when pulling from a cache, Nix still has to resolve the path...unless you are using FlakeHub Cache and fh, the CLI for FlakeHub.

More on fast evaluation times with pre-resolved store paths here: determinate.systems/posts/resolv...

Screenshot of a terminal window where the user ran `determinate-nixd version` and Determinate Nix responded with the version numbers and a message that a new version is available, with instructions on how to upgrade.

Are you running the latest version of Determinate Nix, v3.6.8? Simply run `determinate-nixd version` to find out and `sudo determinate-nixd upgrade` if a new version is available.

Changelog: Lazy trees and security improvements Lazy trees are ready to roll out, and an improvement to the sandboxing security.

Changelog: introducing lazy trees This long-awaited feature makes Nix and flakes dramatically more efficient in a wide range of scenarios

Check out our blog post for all the details about lazy trees in Determinate Nix, including performance benchmarks, other implications, and the upstream PR: determinate.systems/posts/change....

Have you tried lazy trees in Determinate Nix? This major feature shipped in preview mode as part of version 3.5.2 and speeds up evaluation while using less disk space. Make sure you're on the latest version of Determinate Nix and give it a try by adding `lazy-trees = true` to your Nix config.

❄️ #NixOS users: time to switch to Determinate #Nix. 🚀

Now available in our public binary cache. You never have to build it yourself.

This, and MUCH more in our Determinate Nix 3.6.2 release notes: determinate.systems/posts/change...

Finally: tab complete for determinate-nixd.

This and WAY more with Determinate #Nix 3.6.2: determinate.systems/posts/change...

warning: Performing inefficient double copy of ...what?? Determinate Nix 3.6.2 shows you where you're slowing down Nix by needlessly copying your source again.

And guess what: Determinate #Nix 3.6.2 has more improvements just like this: determinate.systems/posts/change...

Okay, okay, I know: *dozens of us* grok set theory. It's fun, but ∆∅ε! They doesn't belong in the Nix interface. And now they're gone: Determinate Nix 3.6.2 uses /words/, not symbols, in the `nix profile` commands.

This and lots more in Determinate #Nix 3.6.2: determinate.systems/posts/change...
