Fascinating. I heard something similar with particle pollution in big cities.

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 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 ?

I am a scientist myself, and I know what the HCERES says about his institute, and also that his institute no longer had support of the CNRS, which is telling considering that the CNRS only very rarely make such moves, as well as editors no longer accepting his papers leading him to create his own self serving journals. My issues with him are his lack of scientific rigor and lack of scientific ethics. Unfortunately, he’s staining the community as a whole, even though he lost support of several scientific institutions long before the Covid.

This guy is a shame for us all, French academics… sorry World, please know we’re not all frauds….

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
