  • Yeah, AMD is lagging behind Nvidia in machine learning performance by like a full generation, maybe more. Similar with raytracing.

    If you want absolute top-tier performance, then the RTX 4090 is the best consumer card out there, period. Considering the price and power consumption, this is not surprising. It’s hardly fair to compare AMD’s top-end to Nvidia’s top-end when Nvidia’s is over twice the price in the real world.

    If your budget for a GPU is <$1600, the 7900 XTX is probably your best bet if you don’t absolutely need CUDA. Any performance advantage Nvidia has goes right out the window if you can’t fit your whole model in VRAM. I’d take a 24GB AMD card over a 16GB Nvidia card any day.

    You could also look at an RTX 3090 (which also has 24GB), but then you’d take a big hit to gaming/raster performance and it’d still probably cost you more than a 7900XTX. Not really sure how a 3090 compares to a 7900XTX in Blender. Anyway, that’s probably a more fair comparison if you care about VRAM and price.

    I forget the exact terminology but I tried putting it into the most permissive mode available. Is still could not work with external hard drives. This was several years ago so I can’t say what might have changed since then, but I did spend some time troubleshooting and at the time that functionality did not work. I’d read that it was possible in the previous version (maybe 18.04?)

    Edit: Come to think of it, it might not have been as simple as “couldn’t access external drives”. It might have had something to do with how my disks were mounted and their permissions and mount points. I remember that I hit a wall at some point and further troubleshooting would have required more surgery on my system than I was willing to attempt.

    Yeah, this kind of things drove me batty on Ubuntu. So many things were delivered as Snaps when they just don’t work that way. The funniest one to me was Filebot. It’s a media file naming/organizing tool…that doesn’t have disk access. Are you kidding me, Canonical?

    Flatpak is easier to work with, but has similar issues. Great for simple things, but I’m always worried that at some point I’m going to need some features that just won’t work, and then it’s going to be a hassle to migrate to a native installation. And it has no CLI support.

    And yeah, the bloat is wild. Deduplication on btrfs (or similar) helps but there’s no getting past the bandwidth bloat.








  • Probably ~15TB through file-level syncing tools (rsync or similar; I forget exactly what I used), just copying my internal RAID array to an external HDD. I’ve done this a few times, either for backup purposes or to prepare to reformat my array. I originally used ZFS on the array, but converted it to something with built-in kernel support a while back because it got troublesome when switching distros. Might switch it to bcachefs at some point.

    With dd specifically, maybe 1TB? I’ve used it to temporarily back up my boot drive on occasion, on the assumption that restoring my entire system that way would be simpler in case whatever I was planning blew up in my face. Fortunately never needed to restore it that way.



  • YES.

    And not just the cloud, but internet connectivity and automatic updates on local machines, too. There are basically a hundred “arbitrary code execution” mechanisms built into every production machine.

    If it doesn’t truly need to be online, it probably shouldn’t be. Figure out another way to install security patches. If it’s offline, you won’t need to worry about them half as much anyway.
