@npub1z98…le0l Ali from the optimum YouTube channel builds an absolute GPU monster in Mac Pro form. Obviously not for you (it's not a Mac), but maybe of interest still, just for the pure GPU horse power that *could* ship with an actual Mac Pro.

@npub12qh…k48x Hey! Was just wondering what happened to Martin's "Fediverse all the things" dedicated-root-server-for-all-services journey? Still ongoing in the background or was it cancelled?

Quite the beefy server! Do you expect your ActivityPub experiments to (eventually) make use of all those resources? Or is this safety overprovisioning?

I see! Just to understand: The disk on which the gocryptfs-protected mount is on, is it full-disk-encrypted as well?

@npub19c6…ttya Regarding your gocryptfs + Syncthing part on the most recent Linux Matters:
Did you look at Syncthing Untrusted (Encrypted) Devices as well?
https://docs.syncthing.net/users/untrusted.html
If yes, why did you decide against it and for gocryptfs as an additional layer on top? I love gocryptfs, just trying to understand the decision process.
