nixpkgs-unfree supposedly provides builds for non-free, but redistributable
packages that cache.nixos.org does not build.
Along with cuda-maintainers, it should reduce the burden for using heavy
packages for machine learning quite a bit. So, lets see how this one goes.
I should also start checking how the machine learning story is with NixOS at
all, it is rife with Python and Python has absolutely horrible ecosystem for
managing dependencies.
upstream NixOS has a CUDA maintainers group now, so future seems to be brighter
for doing ML stuff in NixOS. The non-availability of binary caches was a problem
before but now it seems to be not so any more!
Add this cache for future-proofing this thing.
Finally fully enable binary cache for nix-community and emacs-overlay.
No I don't have to build emacs from scratch for every master update :)
This was done by means of cachix, which is a means to upload built derivations
for others to share with. Nix-community has their own, and it makes using
overlays provided by nix-community that much better. This should shave off 20-25
min per system rebuild.
I am not sure if this will work as is after moving this config to new system,
so here are the steps to follow:
1. nix shell nixpkgs#cachix
2. sudo cachix use nix-community
3. stage/commit cachix.nix and cachix/ from /etc/nixos
4. done
Hopefully this will be enough in the future system move. If not, all the best to
future me.
