• So I ventured to vacuum New House, which is more than twice the size of Old House and carpeted throughout where Old House had hardwood floors in the living areas.
  
  Yeah, I'm going to get a Roomba or some suitable equivalent. That's a lot of carpet.
  
  
  
• The FAA is ordering airlines to update faulty radar altimeters. (Ars Technica)
  
  The argument has been going on for years, with cellular network operators swearing that their equipment couldn't affect aircraft instruments, and airlines swearing that it did.
  
  Turns out they're both right, because the instruments themselves are faulty. The altimeters were designed decades ago when nothing else operated anywhere near that radio frequency, so the designers just didn't bother to filter out other signals. And now that there are other signals, there are problems.
  
  The networks are happy with this decision. The airlines not so much.

• The PCIe 7.0 spec is due out in 2025 - it will be twice as fast as PCIe 6.0, for an aggregate half a terabyte per second per slot. (Tom's Hardware)
  
  A x1 PCIe 7.0 slot will be as fast as a full-size x16 PCIe 3.0 slot.
  
  It took seven years to progress from PCIe 3.0 to PCIe 4.0, and just eight to get from there to PCIe 7.0.
  
  I don't know if or when this will show up in consumer systems, but PCIe 5.0 was adopted very quickly. By Intel. Nobody else is shipping it just yet.
