The arch package has to be built somehow. You could look at that packages source and/or content to figure out how to manually do it on your system, or wait/hope the deb is being maintained and gets fixed.

It’s likely mostly some plumbing, like a systemd service with it’s configuration, to get the audio routed properly.

Just to clarify since it barely came up: NFC can be used for a lot of things, digital payment just being one use case. You can also have “tags” that trigger some sort of automation when the phone is placed there (like on the phone holder in your car, on your desk, on your night stand). You can use it as a key to open doors or locks (bikes). You can transfer your contact information to someone by touching phones together. And so much more.

It’s a universal way to communicate (very) short distances, with the unique property that the reading device can provide power to the item being read if needed. Not a lot of power, but no batteries needed at all for the passive side in many cases.

Doable, not practical. Another major concern is the induced dizziness and general discomfort from such a small circumference. If you stand up straight, your head moves significantly slower than your feet. There are more effects that humans don’t do well with.

In addition keep in mind that this implies significant mechanical complexity the moment you don’t rotate the whole craft, but only a section or ring. If you do rotate all of it, simple tasks like taking a photo become… cumbersome.

Also like others have said, it’s not a permanent residence for anyone, and the main goal of the ISS is the study of low- or micro-gravity.

Somewhere between zero and 16. There is no “usually” for me.

There’s also a dedicated recipe in “bottles”, which I think is based on it at least in part. As I’m trying to move away from fusion, I haven’t tried it yet though. Apparently it can work, but can also randomly break with updates…

There’s also In shape, which has it’s down sides (some go away with money), but also runs anywhere bring browser based. One of the more obvious down sides is that it’s by definition cloud based.

There has been a lot of advances even with Nvidia in recent years. Assuming the GPU in the laptop is semi-modern (not sure if it’s 10xx or 20xx and newer, but one of those), you should be able to just install any modern distro and it should just work. This is especially true for gaming focused distros (like CachyOS), which doesn’t have to be used for gaming btw. They will auto-detect just fine in the installer and there is zero effort or tinkering required.
