But that makes you:

1.) not an average motorist, in no country 2.) not really the target group for current EVs

There will never be a perfect solution for everyone, but that doesn't mean that most people couldn't just switch to an EV without any problems at all

You can.

You have to enable Bluetooth in the SteamVR Settings, and they'll automatically turn off when you quit VR, and back in when you start it up again. Only downside is (at least for me) when you don't use it for a longer time the connection seems to drop, and they won't turn on automatically anymore. But nothing that can't be fixed with a quick un- and replug

It shouldn't really scale above a certain point, it's just that if you import a lot of pictures all at once (in my case with immich-go, as mentioned from a Google photos takeout), all the ML-Tasks (facial recognition, search tagging) together with the normal tasks (thumbnail extraction, video transcoding) can suddenly increase the ram usage from in my case normally 1-2gb to around 6, which even on an 8gb raspi could get a little tight. But for example even just 16gb in the HP should be enough, assuming you don't have a bunch of other stuff clogging up your RAM. As for the CPU, I'm not too sure tbh, I'm using a Ryzen 5 5600G, which can handle everything that's running on my server with ease. I think the only significant downside you'd have here going with 4th gen is power efficiency. I still have an i7 6850K (OCd to 4.3GHz) in my main PC, and that thing uses a couple hundred watts when fully loaded, compared to my Ryzens 65W or so. If you're just going for an i5 or i3 with the fourth gen that's probably not gonna matter too much, but the performance probably also won't be amazing at the same time.

I'd also highly recommend the proper PC, Immich can get pretty RAM-hungry if you use the ML functions, for me that has actually caused crashes before. Granted, that was while importing roughly 20k Assets (200GB) from a Google photos takeout, but it's still probably better to be prepared.

To be fair though, those warnings are not really representative of the current user experience. I've had Immich running for about 6 months by now, and apart from the very frequent updates the only annoyance was when they recently changed their database scheme, and I had to manually add two extensions to my Postgres. Everything else has been rock solid, and has been improving at a massive pace

I'd recommend I'm mich instead of Photoprism, at least for this usecase. I have both running, but I use Photoprism primarily to organize and share pictures taken with my SLR, while Immich handles Automatic Backups and sorting of all the pictures I take with my phone. Additionally Immich has way better (and still offline) facial detection, it's almost scary how good it is sometimes

Could be similar to DIN875 or DIN878, depending on who you ask https://www.scribd.com/document/81939727/Sonderschrauben-fur-den-Maschinenbau

Also ich habe bei mir inzwischen seit fast zwei Jahren Photoprism laufen. Meiner Meinung nach die größten Vorteile sind 1.) es schluckt einfach vorhandene Ordnerstrukturen, ohne sich zu beschweren, und 2.) alle thumbnails und Previews werden vorab (also beim Einlesen) generiert und müssen nur von der Festplatte gerufen werden. Das zahlt man natürlich in Form von mehr verwendetem Speicher, sorgt dafür aber für schnelle Ladezeiten auch bei großen Bibliotheken. Für den BananaPi würde ich dann allerdings einige Features wie die Gesichtserkennung per ML abdrehen. Dinge über Links verteilen geht natürlich auch, dafür braucht man allerdings, logischerweise, eine Domain und alles was dazugehört. Bei mir ist das einfach Nginx Proxy Manager mit einem Let's Encrypt Zertifikat.

Um etwas direkter auf deine Frage einzugehen, ich hab Mal einen ganzen Haufen Bilder mit ffmpeg zurechtgeschnitten, das lässt sich wunderbar einfach automatisieren und ist auch ziemlich effizient, auf einem i5 8.Gen (weiß das genaue Modell nicht mehr, aber ein Laptop 4-Kerner) waren es 7-9fps. Hier gibt's einen ganzen Haufen Example-Commands: https://stackoverflow.com/questions/28806816/use-ffmpeg-to-resize-image
