Remote NixOS deploys get dramatically faster when the target host fetches public dependencies from its own substituters and you only push the private bits. The key is `--use-substitutes` and the trusted-user detail most guides skip.
NUR flips the AUR model inside out. Instead of one giant package repo, every maintainer keeps their own repository and NUR indexes the lot. That gives you composability, selective trust, and a much wider ecosystem than most Nix users realize.
Turning nftables rule counters into Prometheus time series with a custom exporter and Grafana dashboards, using rule comments as stable human-readable labels.
For headless Raspberry Pi bring-up on NixOS, image-time secret injection is often more reliable than first-boot decryption on the device. Here's the provisioning flow, the brittle design we tried first, and why bootstrap state belongs under /var/lib rather than /etc.
Get Gardena smart system data out of the phone app and into Prometheus and Grafana with a Rust exporter, a NixOS module, and per-valve water-use estimates that are honest about what the hardware can and cannot measure.
A practical BorgBackup setup for NixOS with rsync.net: the manual CLI basics first, then a clean declarative `services.borgbackup.jobs` configuration with `sops-nix`, retention, pre-backup dump chaining, and restore verification.
Why the existing Python and Go gpsd exporters keep crashing, how a Rust rewrite fixes it, and wiring the whole thing up with Prometheus on NixOS — including the gpsd configuration that nobody tells you about.
Building hickory-dns from source with Nix, generating zone files from a host registry, wiring up DDNS with Kea DHCP, hardening with systemd, and monitoring the whole thing with Prometheus and Grafana.
Building your own private Cachix-style Nix binary cache on NixOS with Attic, Garage, PostgreSQL, sops-nix, multi-tenant token scoping, and GitHub Actions.
Getting Ecowitt weather station data into Prometheus and Grafana with a Rust exporter and a NixOS module — with forwarding to Home Assistant and other receivers.
Setting up a self-hosted, vendor-neutral container registry on NixOS using the Zot module — users, access control, retention, nginx, and monitoring included.
