Iirc I had to check in my checked bag before going through security. Also had no problem with putting my Nintendo Switch and controller in my checked bag.

Although I only flew within the EU, so different regulations may have applied than in the US.

Afaik you should be ok as long as you have it in your checked luggage, not your carry-on bag

I do push only, as I’m using cloud-based object storage, so I know the destination is online 24/7. I do encrypt them before uploading, so couldn’t care less about privacy or security. Only availability, but if one uses multiple different cheap storage providers and replicates the backups, it doesn’t matter either.

It’s also easier and more secure to automate push if you don’t fully own the destination.

I’m using headscale with headplane as the UI, looks like tailscale, is feature complete (at least it says so on their GitHub readme). Headplane even integrates with an external OIDC provider (I self-host Keycloak for centralized identity management across my services).

Only mechanically. You could technically remove the small piece of plastic at the end of the slot, and still put a x16 card in a x1 or x4 slot, should work anyways. Some mainboards even have open-ended slots directly instead of closed ended. Haven’t done it and wouldn’t recommend it, but it would technically be possible.

If every single dispenser is a self contained unit, which then is put together in groups of how many different kinds of drink you need? That seems cheaper than having each group of dispensers individually built because all displays have to be wired up to a single computer. This way a single dispenser can be replaced quickly without needing a technician to come or replacing the whole thing.
