Just got ComfyUI running on NixOS 🚀 NVIDIA + CUDA + uv + direnv, no global Python, no home dir mess.

Took less time than expected. Will write a proper blog post later.

70,000 steps target, finished at 69,543.

Fixed the tag pollution issue. Defined a new taxonomy note_tags in config.toml to separate lightweight note tags from serious blog tags.

Also fixed the listing layout:

• Created templates/note_tags/single.html
• Used the paginator object to handle the timeline feed view.
• Added custom CSS to style the filter header.

Right now I keep all my Nix files centralized, build on my desktop, and push changes with nixos-rebuild --target-host. Thinking about experimenting with disko + nixos-anywhere next.

• nix-community/disko: Declarative disk partitioning and formatting using nix [maintainers=@Lassulus @Enzime @iFreilicht @Mic92 @phaer]
• nix-community/nixos-anywhere: Install NixOS everywhere via SSH [maintainers=@Mic92 @Lassulus @phaer @Enzime @a-kenji]

After nix flake update nixpkgs-unstable, the build failed because it tried to evaluate tree-sitter-razor, which is marked as meta.broken, even though I do not use Razor at all.

This happened because my Emacs configuration was using treesit-grammars.with-all-grammars, which evaluates every available tree-sitter grammar.

Switching to treesit-grammars.with-grammars and explicitly listing only the required grammars resolved the issue.

Refactored my NixOS firewall setup. I migrated from the deprecated meter syntax to dynamic sets in nftables.

I've launched my YouTube channel! 🎥 No videos yet, but stay tuned! ✨

Virtual Memory

yay!

Completed the integration of Nix files for three running NixOS machines. I still have three more left to convert, but this setup makes the process significantly easier.

Optimizing the integration of my nix files. Upon closer inspection, I found gaps everywhere—some necessary services had actually stopped.

I thought I knew better than to rely entirely on AI, but clearly I didn't. Human verification is essential after all. Glad it didn't turn out to be fatal.
