![immich](immich.webp)

Right now Immich is the only service I am running with containers rather than native Nix modules (as you can see in [this configuration file](https://github.com/Logan-Lin/nix-config/blob/master/hosts/nixos/hs/containers.nix)). Technically it is possible to set up Immich with pure Nix modules, but for this type of services that rely on specific versions of databases (in this case, PostgreSQL with vector support), I feel containers are the easier route.
And to be honest, I don't think there is much benefit going with pure Nix module here (especially for Immich which you can still [declare its config](https://github.com/Logan-Lin/nix-config/blob/master/config/immich.nix) even with containers), other than fulfilling the purism many Nix users seem to have.
Also, I am not using Docker but Podman instead, which is said to have better integration with NixOS. From my experience it is fairly declarative and efficient, should be practically nearly identical to running directly on the host.

### Reference Management: Zotero
[Zotero](https://www.zotero.org/) is a reference management software that can be used in a variety of scenarios. For me, I largely use it to manage academic papers I need to read.
![Zotero](zotero.webp)
> Zotero desktop UI, showing list of papers.
Zotero has a built-in cloud sync functionality but their price for storage upgrades is quite high. One thing you might not know is, Zotero stores metadata and attachments in the same folder. You can use Syncthing to sync that folder, and completely ignore the official cloud sync functionality.

### Paper Writing: Overleaf vs. Local Text Editor

![Calibre](calibre.webp)
> Calibre desktop UI, showing list of books.
Similar to Zotero, Calibre stores all the books and metadata of a library in a local folder, so there is nothing stopping you from syncing the folder across multiple computers. Although this is something explicitly suggested against by the software (a line when you select the location for a library: "Note that putting the calibre library on a Networked drive is not safe"), from my experience, as long as you don't try to open and modify the same library on two synced computers simultaneously, you won't be running into any issues.
