TODO!!! Even this is hard to find! A clean and minimal one! Why! All we can find are shittly levitating YBCO samples in liquid nitrogen! Maybe because liquid helium is expensive?
First 10T Tape Coil by Mark Benz
. Source. Dr. Mark Benz describes the first commercially sold superconducting magnet made by him and colleagues in 1965. The 10 Tesla magnet was made at GE Schenectady and they sold magnets to research facilities world wide before the team formed Intermagnetics General. IGC and Carl Rosner went on to pioneer MRI technology.Online and free. Pay only for exams, i.e. exam as a service. Almost perfect according to Ciro Santilli's idea.
As of 2023 the most important ones economicaly were:The main application is magnetic resonance imaging. Both of these are have to be Liquid helium, i.e. they are not "high-temperature superconductor" which is a pain. One big strength they have is that they are metallic, and therefore can made into wires, which is crucial to be able to make electromagnetic coils out of them.
- Nb-Ti: the most widely used one. Used e.g. to create the magnetic fields of the Large Hadron Collider Up to 15 T.
- Nb-Sn: more expensive than Nb-Ti, but can reach up to 30 T.
TP-Link Archer VR2800 router Virgin Media Hub 3.0 Wifi setup by 
Ciro Santilli 37 Updated 2025-07-16
Ciro Santilli 37 Updated 2025-07-16- "Operation mode" > "Wireless router mode" (was "DSL Modem/Router mode" by default).
- "Network" > "Internet" > "Add" > "Internet Connection Type" > "Dynamic IP" > "Save"
Custom configs we had, not sure if mandatory:
- Dynamic DHPC mode
- Unicast DHCP
Wait for TP link to fully reboot.
Connect port 4 of tp link (marked WAN/LAn) to port 1 of VM Hub (unmarked, but it is magic, has to be port 1).
Finally, AFTER everything else is setup, turn on the Hub and wait for a few minutes. It ONY WORKS if you turn it on after everything is setup.
Outcome:
- hub light turns purple: www.reddit.com/r/VirginMedia/comments/c703t6/purple_light_on_the_box/
- Archer WAN light turns on white. Not red. Red means error
- you have Wifi. Notably, the 5G Wifi is way way faster and reaches the WAN limit of 256 Mbps.
- Ethernet does not work anymore on either Hub nor Archer, Wifi only. But it doesn't matter because the 5G Wifi already reaches the speed limit.

Things actually have gotten more and more closed, e.g. of stuff getting paywalled with time:
It appears that things got really bad starting in 2017, possibly when WebLearn was introduced. When things migrated to Canvas, they were closed by default, apparently with any mechanism to publish publicly.
Therefore, they managed to make things more closed than when teachers would just upload to good old
ox.ac.uk/~name static websites!!Ciro Santilli has also heard that some people in the Mathematical Institute of the University of Oxford opposed to moving away from their Moodle instance precisely because the new options did not support open publishing, so kudos to those people. But most teachers likely don't care and just do whatever is the best internally supported default.
Their "open" video material: podcasts.ox.ac.uk/ A somewhat small part is Creative Commons, but most proprietary. Despite the name "podcasts", they do contain video, it is just a relic.
podcasts.ox.ac.uk/open contains actual Creative Commons only it seems.
It does however appear that professors own their lecture notes, so there some hope maybe: governance.admin.ox.ac.uk/legislation/statute-xvi-property-contracts-and-trusts#collapse1383636
