if you see a community for the first time, it will take a while to load the last 20 posts on that community. after that, every time an update is done on the remote community, it will be pushed to yours.

idk if at least one person need to subscribe to it, or just opening it is sufficient.

add multi community aggregation to aggregate communities of the same topic on different instances.

there is an app for mobile. that also offer continuous backup of photos (like gphoto)

that's because i run manjaro on my main machine, all the benefits of arch + simple intsall

it does not matter the instance where you create your profile or community, all are federated. small instaces run better because lemmy is (not yet) good at scaling.

I did a project for an university exam, published it on github and a company hired me for it.

please put the text of the article in the description.

this is so damn useful

immich!

no idea, you should search issues on github.

Anyway comments are replicated across all instances, so nobody stops someone from running a modified instance that does not abide to the comment deletion request. Same for posts, idk about images.

you should consider everything that get published public forever.

there is comment edit history, even if you edit them the original will still be visible
