  • It’s not just cores - it is higher performance per rack unit while keeping power consumption and cooling needs the same.

    That allows rack performance upgrades without expensive DC upgrades - and AMD has been killing dual and quad socket systems from intel with single and dual core epycs since launch now. Their 128 core one has a bit too high TDP, but just a bit lower core count and you can still run it in a rack configured for power and cooling needs from over a decade ago.

    Granite rapids has too high TDP for that - you either go upgrade your DC, or lower performance per rack unit.








  • I’ve been using an Arm notebook with Windows for over a year now (not as main system, but development system for a customer project). I’m running a lot of x86 software (like Emacs) as a gcc port for Windows/Arm is being developed only now - with no problems. It integrates nicely into the native stuff - which is one area where you run into issues on the Mac: If you start a shell in rosetta it’s annoying to make calls to native arm binaries.

    The only issue I ran into were some drivers not available for Arm - emulation layer (unsurprisingly) just is for userland, not kernel drivers. Also x86 emulation isn’t working well if Windows is running in a virtual machine on MacOS - but supposedly that’ll be fixed in the upcoming Windows release.

    All of this only applies to Windows 11 - if for some reason you decide to run Windows 10 on Arm you’re in a world of pain.



  • x230 with x220 keyboard also is pretty nice - but unfortunately no longer suitable as main notebook. As nothing useful came out of lenovo after that, others are even worse, nobody has a decent trackpoint and sensible amount of RAM only exist for macs I ended up with one of those for work few months ago.


  • Pretty much same here - I kept an x230 alive until I had to accept earlier this year that it just is bad for overall productivity, and ended up getting a macbook. None of the newer thinkpads are good - and they’re still one of the less bad manufacturers.

    There’s also enough stuff I don’t like about the mac - but the current keyboard is one of the better notebook keyboards available right now, and if you want long battery life, lots of RAM and a lot of CPU power available in a compact device they’re the only manufacturer currently offering that.



  • It should work - possible that it won’t let you create a one disk raid 0, but creating a one disk raid 1 and then converting it to a two disk raid 0 should word. It’s been years since I played with a pure raid 0 (don’t see much sense in them), but managed conversion back then.


  • If your install is using LVM (which anything installed over a bit more than a decade should be) you can set up the new second drive as a RAID with a missing device, add it as additional PV, use pvmove to move all PEs to the RAID, remove the old PV, and now add that disk to the RAID.



  • It’s already in the name - XDG stands for X Desktop Group (nowadays freedesktop), which works on interoperability for desktop environments. In a pure shell environment (or even if you’re not running a full desktop) none of the XDG variables are defined, and especially in shell environments the default fallbacks specified by XDG are not necessarily what the operator would expect.
