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)

if they have the same hash the deduplication thing will work. if they are different quality or other stuff no. thare are plans to implement something regarding more advanced deduplication but not anything implemented at the moment.

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.

please put the text of the article in the description.

this is so damn useful

immich!

and works on mobile too
