Keep in mind that superconductors have a critical current below which you have to be if you want to stay in the superconductive states. So for a superconductor to be useful for energy transport, this current has to not be tiny. I haven’t had the time to read their paper so I don’t know the value of the critical current. Also if for some reason the current suddenly goes beyond the critical current, the wire will heat suddenly, with possible damage…
My understanding is that they also need low thermal noise to ensure pure states. They cool much below the superconduction threshold temperature (eg typically 20 mK). So I am not sure that this would be useful for quantum computers at the moment. Magnetic field productions such as that in MRI requires high current, so that depends on the maximum current that this material can sustain before that breaks superconductivity. So it could perhaps turn out useful or totally useless. Hard to say at the moment.
I have a second-hand iPhone 7, my wife has an iPhone 6s. Neither supports iOS 16. The iPhone 7 was discontinued in 2019. I try to keep things for as long as possible for ecological reasons, eg most of the carbon footprint lies in the manufacturing and recycling. Besides, I don’t use the phone for gaming, which might be a reason why I haven’t noticed it being particularly slow (unlike my previous phone which was a iPhone 4s and was getting significantly slower over time).
I like the Password for Nextcloud app. I self-host mine, but I think there might be Nextcloud instances that you can access. It is encrypted, and has an app for smartphones.
Do we know that this is the one and only domain that they will use when and if they actually enable federation ?
It requires iOS 16 😭
Something very simple on the web client: a setting to get links to open in a new tab, to make it easier to get back to the same point in the comments.
I am doing it because it is fun and it is a way to try to understand how things work. I am still not sure whether my answers successfully propagate to all servers.
Yes you need a domain but that is usually quite cheap
Fascinating. I heard something similar with particle pollution in big cities.
