I'm so proud for Nix and @github: Dependabot version updates now support the Nix ecosystem, via flake updates. Extra proud that they link to Zero to Nix, our love letter to flakes.

The native Linux builder for macOS from @DeterminateSys is great. I'm building containers using dockerTools.buildImage and I was previously letting CI build and tag my images and having my local k8s pull those in, but now I can do that all locally!

nix + direnv + nix-direnv is peak developer experience. Write a flake.nix with a devShell, add some packages from nixpkgs, add `use_flake` to .envrc. Just cd into your project directory and you're good to go. Good bye dependency problems.

Pretty stoked that FlakeHub now supports Okta, meaning access to your private Nix caches is gated on your enterprise's existing SCIM/SIEM regime. docs.determinate.systems/gui…

Okay, from top to bottom. ✅GitHub Codespaces ✅Docker Compose ✅Devcontainer ✅Debian Trixie 13 ✅Systemd ✅@DeterminateSys Nix Installer ✅Nix Flake Now to develop the flake itself 👩‍🍳🔥✨
A Visual Studio Code window with dark theme is open on macOS, connected to a GitHub Codespace for the repo “kalilix.” The left tree shows files like flake.nix, devcontainer.json, docker-compose, setup.toml, and .config/mise for task automation. The center terminal shows logs from a devcontainer running docker.io/library/debian:trixie (Debian 13) with nix installed. Output includes systemd startup, a process tree with /lib/systemd/systemd, nix develop, dbus-daemon, nix-daemon, and vscode-remote processes, ending with “Outcome: success” and “Finished configuring codespace.” The right terminal runs nix flake show inside the shell “kalilix-base-env,” listing devshells for aarch64-darwin, aarch64-linux, x86_64-darwin, and x86_64-linux, with omitted entries for python and rust, plus overlays including Nixpkgs. Git remote -v confirms origin at github.com/usrbinkat/kalilix. Technically, this shows a flake-managed devcontainer built with Docker Compose. Nix flakes handle dependency management,

Stoked for this. Determinate’s GitHub Action is a slam dunk. If you have a working nix flake for your local builds, making it work in CI w/ Determinate is painless.

Parallel evaluation has arrived in Determinate Nix! The 3.11.1 release cuts evaluation times by 2x OR MORE in many cases. We also fixed a macOS issue and improved the default flake template. You don't want to miss this one. Link in thread 🔗👇🧵

What a slam dunk of a feature release. I'm not familiar with nix internals, but I'm surprised there isn't already more parallelism there, given how well the purely functional approach lends itself to that sort of thing.

We'll be rolling out Determinate Nix 3.8.0 today, with some nice improvements on `nix flake check` and flake locking. Also, we'll be rolling out lazy-trees to 20% of users (up from 5%) after an extremely successful 5%. The perf benefits of Determinate Nix are pretty intense.
