• So, that new room-temperature superconductor announcement?  Maybe not, say other scientists.  (Science)
  
  And one of the tests supposed to illustrate its superconducting properties might just be demonstrating Lenz's law.  Superconductors respond in interesting ways to static magnetic fields, but regular conductors can respond in similar ways to changing magnetic fields, so the actually demonstrate superconductivity you have to keep your field static, which they kind of completely failed to do, at least in one particular video.
  
  It's not fraud or anything, since the paper describes exactly how to create the alleged miracle material, just possible bad research.
  
  
  

Tech News

• Elon Musk is the main reason why Tesla Model 3 owners are switching to other EV brands.  (Notebook Check)
  
  Terrible, terrible headline, because the actual story points out that of the Tesla customers who did sell their Model 3 and buy a different brand, 21.5% said it's because they're mindless Marxists angry that Twitter is no longer their own personal hugbox.
  
  
  
• Speaking of hugboxes Ars Technica managed to cover a Falcon Heavy launch of a 10 ton EchoStar satellite without the comment section turning into the Two Minute Hate in the first page.  (Ars Technica)
  
  There are a couple of such comments on page two but they got downvoted into oblivion.
  
  Good for you, Ars Technica.  Keep it up and we might be able to let play with the other children again.
  
  
  
• The latest Windows 11 update - currently only in the preview channel - breaks third-party apps that fix Windows 11's shitty start menu.  (PC World)
  
  If this makes its way to release I'll go ahead and reinstall this laptop with Windows 10 as planned.  Good litmus test of whether Microsoft cares at all about its paying customers.
  
  Windows 10 at least has the signal virtue that it's been abandoned except for security patches so Microsoft isn't actively trying to break it.
  
  
  
• Intel's 3nm node is on track for next year, says Intel.  (Tom's Hardware)
  
  TSMC started first production of 3nm last year, as did Samsung, but their respective 5nm processes are still used for most leading-edge chips.  Apple's next iPhone - later this year - may or may not have a 3nm chip.
  
  Next year we should see lots more 3nm chips from all three manufacturers.
