Just read a comment about exactly this a few days ago. Anyone working on space components know that a very hat problem to work on is how to keep things cool because, well - having the fucking sun shine on things most of the time directly without the ozone layer and air to dissipate heat in and way does make things go hot.

Also, you forgot a very important thing a data center needs: people that work there. That is one of the reasons we currently build data centers so close to urban sprawls in Arizona instead of somewhere in the middle of Alaska or in polar regions. There must be personnel working onsite all the time.

Ente worked for me. More pricey, yes. But you do not pay with your data… Also e2e encrypted, good family plans and sharing works good.

And one of their backup locations is an underground bunker

Did you just turn off all transcoding or pre-transcoded to 720p mp4 (or similar)?

Or did you just rely on the native apps for direct play?

Paperless, I guess OCR is very taxing, but I mainly had RAM problems regarding this on my Pi 3, with only one doc at a time, it went slow but steady.

Immich maxed out my i5 (all cores on 100) for some minutes when running the ML on my imported test library of ca. 3k Files. So yeah, when choosing the Pi4, I’d go with ente for sure!
