  • 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.


  • Screen is another thing - but I can live with that, mostly - it’s a bit hard to find x86 notebooks with decent resolution (not talking retina style, just better than “1080p on a 14 inch display”). And while the screen itself is nice on the apples I’d prefer a lower resolution one if I can get a matte screen instead.

    But fact is that nobody wants to sell you a proper x86 notebook. It’s almost impossible to find something with more than 32GB of RAM, and while there are a few with more than 64GB they’re all xeon based monsters larger than 16", as far as I can tell can’t really be ordered, and have a price tag equal or larger to a full spec 14" mac book pro. And obviously you can’t really think about battery life with intels space heaters.

    It’s especially sad as current mobile Ryzen CPUs could very well compete with Apples ARM CPUs - the one thing Apple is better at is the absolute low power state, as soon as it has too actually do something the power (and TDP) curve is very close to mobile Ryzen. But pretty much every manufacturer fucks up the thermal design, or gimps it in other ways.





  • The space used by the smallest solar charger I’ve seen on Amazon seems to be similar to 6 or more batteries in the format the N900 was taking - so if you look at space, slow charging from solar charger, and reliance on sun conditions taking individual batteries seems to be the better option for a few days hike. It’s also easier to stow individual batteries to wherever you still have space left.



  • 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.
