Not really, if absent means "no change", present means "update" and null means "delete" the three values are perfectly well defined.

For what it's worth, Amazon and Microsoft do it like this in their IoT offerings.

Rust has perfectly fine tools to deal with such issues, namely enums. Of course that cascades through every bit of related code and is a major pain.

In the bottom picture it looks like the top "port" is just an air intake.

I would guess a swappable battery would be separated from the vehicle, similar to a gas bottle for a grill.

The battery would be rented for a small deposit and on swapping you only pay the energy + service fee.

I guess you could also buy one to own, but then could not swap that.

That's how it would make sense, at least.

Back in the day Signal was a Qt app, did that change?

The option to use TOTP is already well hidden. It's not like someone who does not know what he is looking for and uses an Authenticator already will accidentally select it.

I mean, other file sync apps upload everything to a third party while you're working with the device.
Then, when you use another device the first one can be turned off.

Solaar usually works well enough. Not sure if the gestures part is supported on MacOS.

I usually avoid depending on "hardware support" software for reasons like this. Once the software is no longer supported or as seen here, introduces some dumb "feature", it becomes annoying.

Then why does the kernel have a crypto API?

Checkmate, Satoshi Torvalds!

Most x86 EFIs are, so the comparison is not really fair.

That's Canonical building Mir 2.

How can the ISP force their dns? They can't know where you got the destination ip from.
