• You can't run MongoDB 5.0 or later on Linux under VirtualBox on Windows 11.
  
  Which doesn't affect most people at all, but one of the reasons I wanted a laptop with 64GB of RAM and 4TB of SSD was so I could have a complete test environment with two virtual servers in a cluster running all my code, and we use MongoDB a lot at my day job.
  
  The reason it doesn't work is that Windows 11 is already virtualised - a lot of the new security features depend on virtualisation, and so does WSL2 if you use that.  So when you run VirtualBox you are running a virtual environment inside a virtual environment.
  
  Which with earlier versions of VirtualBox simply didn't work.  Now it works, unless you want to run specific programs - like MongoDB - that use the AVX instruction set.
  
  Why the AVX instruction set is disabled in this case I have no idea.  The VirtualBox window has a little turtle icon to indicate it's running under Microsoft's Hyper-V paravirtualisation system and thus suffering from institutionally-enforced mental retardation, but the only fix is to disable WSL2 and all the new security features.
  
  Or upgrade to Windows 11 Pro.  Or backgrade to Windows 10.
  
  Or Linux.
  
  Laptop hasn't crashed today so yesterday's incident may have been due to my messing around trying to get VirtualBox working.
  
  
  
• Samsung's new 27" 5k monitor is here.  (Tom's Hardware)
  
  It costs $1600 where Dell's 32" 6k monitor costs $2400, so while yes, it is cheaper, if you're in the market for a high-end professional monitor I'm not sure that you're going to quibble about the extra $800 for a larger, higher-resolution screen.
  
  Also the Samsung has built-in smart TV features, which many people would pay to avoid.

• Is the Radeon 7800 a 16GB Radeon 7700?  (Tom's Hardware)
  
  Maybe.  If so it would be no faster than the previous generation 6800, but would leave plenty of room for a faster 7800 XT model.
  
  And if the price is right - no more than $500 - it could kick Nvidia where it hurts.  Well, actually, it won't hurt at all because Nvidia is swimming in an AI startup money pool at the moment, but it would at least make a good graphics card for normal users.
  
  Nvidia's RTX 3060 Ti caught a lot of flack for having just 8GB of RAM on a 128 bit bus.  The 7700 will have 12GB of RAM on a 192 bit bus, and the 7800 will have 16GB of RAM on a 256 bit bus.  So unless AMD screw up the pricing - which they probably will - they should have a much more attractive offering in the $400-$500 range.
  
  
  
• JumpCloud, an IT firm serving 200,000 orgs, says it was hacked by nation-state
  "Extremely targeted" attack involved a data injection into JumpCloud's commands framework.  (Ars Technica)
  
  This is legally-mandated security breach disclosure speak for "some idiot clicked on a link in an email".
