I’m not sure what you mean by this. Copyparty is a fileserver that I’m using for quick sharing of files and folders with others. “Managing multiple devices” is not what I would use it for, whatever you might mean by that. It does have one-way sync, if that’s what you’re looking for.

My RSS reader, Akregator, has an option to open every article in an embedded web browser. I use this feature precisely for these kinds of situations. Most artists that I follow have their own websites with proper RSS feeds, but others only post on Bluesky or similar, that also only show the title and body text. If I can’t follow them through RSS, I just don’t follow them at all. I can’t be bothered to have their newsletter clog up my inbox or use some third-party service that will probably shut down when I least expect it to.

What exactly are “notes”? CalDav has a to-do feature that might do what you need it to do.

And I thought that the Dead Internet Theory was something that we were meant to strive against…

You may self-host your notes or calendar, but you’re forced to either recreate account systems or give up on interoperability.

I literally just finished setting up Radicale on my old laptop, and now I can access my calendar and contacts through CalDav and CardDav from every single client under the sun. Maybe don’t use AI to write your entire article. I won’t even bother reading the rest of the article if you don’t even get this right.

I’ll caution against nextcloud […]

It is indeed rather big and clunky sometimes, but there’s one feature that I really love that I could not really live without. I just tried out Seafile, but I didn’t like the whole “libraries” concept, because it made it very difficult to exclude certain subfolders that I didn’t want on a certain system or to sync multiple local folders to multiple remote folders. I’m using Nextcloud to sync my Documents, Videos, Pictures and Music folders across all of my devices, but I don’t need every single subfolder there downloaded to every single device that I use it on. I also use it to sometimes sync game save files for the ones that I don’t have on Steam. Would you happen to know a better solution than Nextcloud for something like this? I’m currently migrating it from a Raspberry Pi 2 to an older laptop that I have laying around, and I’d happily use a different syncing solution for this, and set up other features that I used (CalDAV, CardDAV) on other containers.

P.S Syncthing looks like what I might need, but I do wonder how I can make public share/upload links with it.
