For the record, you don’t have to take “everything else” out first. It’s actually quite accessible once removing the Steam Deck back plate, which is easily done with a Phillips head screwdriver. The bulk of the 2-4 hour estimate on iFixit is dealing with the battery adhesive. (source: I’ve opened my Steam Deck to swap the SSD, and I just opened it to attempt a band-aid fix to the right bumper after dropping the Deck directly on it while waiting for the part to restock)

Realistically, going down to 12GB System RAM from 15GB is not very noticeable compared to going from 1GB to 4GB VRAM and so I think it should be preferred. If you ran into issues with a very RAM heavy game (unlikely), you could change it to 14GB + 2GB, or go all the way back to 15GB + 1GB. If you are using the Steam Deck on an external display that is higher resolution than its native 1280x800 display, you should probably do 12GB + 4GB to make room for higher resolution textures. Haven’t tested this, but if there were noticable differences, I would think these are the most likely scenarios for them to crop up.

Or the technology could just share the information it needs to share and not everything and anonymise the data ;)

It does. If it “anonymized” the data before broadcasting it to the federation, usernames would not be valid across federated instances.

If I post on instance A as “John” but my username gets anonymized as “UserA893SAJ”, any instance other than A has no idea that that is John, and therefore it is just some anonymous user.

It’s totally possible, but that’s not what Lemmy wants to be

Edit: Yeah no, in cases where attribution is not necessary, like upvote/downvote, they really should be anonymized between Lemmy instances.

I wonder why it isn’t at the moment. Possibly just didn’t have the foresight. I could look into contributing that possibly if someone isn’t working on it already
