My default
nix
configuration on NixOS.
This configuration is more for building/debugging stuff and caching with
nix-serve.
Usually my package version is locked since different
versions of
nix can have some effects.

I thought about posting notes on Syncthing but then I’d have to tangentially talk about NixOS. NixOS is my main Linux distribution but Nix/NixOS/Flakes are too hard to write about and I fear they’ve ventured too far into the realm of over–engineering.
What do I mean by over–engineering? An over–engineered tool is one where even the simplest use cases are non–obvious (to most people) and this can happen when it tries to do too many things with “specificity”. The overall concept is elegant though (explainable in lay terms) and can be applied in other contexts.

I feel sorta conflicted about
my posted notes
on nixops because
shortly after that I discovered
nixos-rebuild had remote deploys. Now
nixos-rebuild itself is just a
bash script
and taking a peek inside is well, you know.. enlightening. There’s even a
NixOS deployment tool written
in just nix. I use
nixos-rebuild…
nixos-rebuild switch \
--target-host "nix@remote.host" \
--build-host "localhost" \

The nix packages collection has a
neat library repository. A small
nudge can
make it completely standalone.
Basically it allows experimenting quickly with configuration patterns for custom
stuff without an expensive evaluation.
