That is an odd question. I'm assuming you want to keep this on the device, but if not would a script that monitors the website on a desktop or server and sends a notification work? It looks like ntfy runs an instance you can use so you wouldn't need to set that up. You might be able to combine it with macrodroid to set off an alarm from the notification.

Marketing wouldn't be very good at their jobs if they were honest like that

Oh dear, we've encountered the Baffling Sounds Of Dragon error. Recommended fix is a restart, tucking your dragon in with a plushy for the night.
Neuro divergent flirting, silly
@LianSirenia
yes, if we can take breaks to infodump to each other on what we're working on :3
@foone
So they crash faster, then

Other annoying problems: I've yet to encounter a spellcheck that lets me type "realise" without it marking it as wrong, or "correcting" it for me. I guess Merriam-Webster is more to blame for that one.
@avghelper
Fractal maybe? It's a gnome toolkit app, dunno how you feel about that

I'm curious what you think of bottles (I don't think it'd have helped in this case, and it's far less integrated than what you plan, but it seems nice for managing multiple versions of wine, at least)
@luna
Glad you got it working, in the end! It's nice to read the journey and dead ends too

I very recently just setup Iceshrimp.net, but the main reason I chose it is unlikely to be important to your use. I wanted to be able to react to posts with custom emojis :3
gotosocial seems like a solid choice, but you need to bring your own front end that is compatible with the mastodon api. I set it up before I realised this was not suitable for me because it lacks custom reactions. If you only use the app that shouldn't be a problem, and rrees.me/2024/03/24/alternative-mastodon-frontends/ has a few web front ends.
I imagine most servers have a setting for how long remote media should be cached, for example gotosocial the default is 7 days. This won't affect the photos you upload.

As for federation I think that servers discover you when you follow someone on that server, or someone on that server follows you. I don't think a relay would help people find you but it could help you find others. But I don't really know for certain.
I'm starting to recognize when a mutual has already reacted to a post on my timeline by the reaction used

I don't even care for the term sideload. It's my device. I'm installing something on it.
I feel like windows at least has already normalized getting signed my a microsoft cert or whatever, it shows you a big scary warning if you run something that isn't. But bypassing it is two clicks; more info and run anyway. Or something like that.
