  • Personally I went with an ITX build where I run everything in a Debian KVM/qemu host, including my fedora workstation as a vm with vfio passthrough of a usb controller and the dgpu. It was a lot of fun setting it up, but nothing I’d recommend for someone needing advice for their first homelab.

    I feel like that has more to do with the complexity of solving your use-case in software rather than anything to do with the hardware. It’d be just as hard on a pre-built NAS as on a DIY build; though perhaps even worse on the pre-built due to shitty OS software.



  • If you had 80GB worth of websites that did something actually useful with it, you’d want Firefox to use it all.

    I usually have dozens of tabs loaded due to usage and I want Firefox to keep all of them into memory so that I can switch between them quicker.

    Though I do also want Firefox to shed load by unloading some of them whe I need memory for something else. There just simply isn’t a mechanism in Linux to do that AFAIK; Firefox will happily keep all of its tabs loaded all the way until OOM eventhough it could shed most of them with little impact on user experience. There isn’t a way for the kernel to ask applications to shed memory load on their own and I think there should be.
    macOS has such a mechanism and Firefox uses it but it didn’t have much effect IME, so it might have been bugged. That was a good while ago that I tested it though.






  • Your currently stated requirements would be fulfilled by anything with a general-purpose CPU made in the last decade and 2-4GB RAM. You could use almost literally anything that looks like a computer and isn’t ancient.

    You’re going to need to go into more detail to get any advice worth following here.

    What home servers differ most in is storage capacity, compute power and of course cost.

    • Do you plan on running any services that require significant compute power?
    • How much storage do you need?
    • How much do you want it to cost to purchase?
    • How much do you want it to cost to running?

    Most home server services aren’t very heavy. I have like 8 of them running on my home server and it idles with next to no CPU utilisation.

    For me, I can only see myself needing ~dozens of TiB and don’t forsee needing any services that require significant compute.

    My home server is an 4 core 2.2GHz Intel J4105 single-board computer (mATX) in a super cheap small PC tower case that has space for a handful of hard drives. I’d estimate something on this order is more than enough for 90% of people’s home server needs. Unless you have specific needs where you know it’ll need significant compute power, it’s likely enough for you too.

    It needs about 10-20W at idle which is about 30-60€ per year in energy costs.

    I’ve already seen pre-built NAS with fancy hot-swap bays recommended here (without even asking what you even need of it, great). I think those are generally a waste of money because you easily can build a low-power PC for super cheap yourself and you don’t need to swap drives all that often in practice. The 1-2 times per decade where you actually need to do anything to your hard drives, you can open a panel, unplug two cables and unscrew 4 screws; it’s not that hard.

    Someone will likely also recommend buying some old server but those are loud and draw so much power that you could buy multiple low power PCs every year for the electricity cost alone. Oh and did I mention they’re loud?





  • It was being compared to another implementation.

    I’m quite certain it was being compared to mainline WINE, so no esync or fsync which themselves usually double FPS in CPU-bound scenarios.

    Hers is actually better

    [citation needed]

    From what I gather from the ntsync feedback thread where some users have tested the WIP patches, it’s not clearly better than esync/fsync but rather slightly worse. Though that isn’t very clear data as it’s still in development. Still, if it was very clearly better than the status quo, we should have already seen that.

    can be fully implemented in Wine

    It cannot, hence the kernel patch.

    It’ll be better but no one really knows the full concrete extend of improvement until it lands

    I see no reason to believe it should be “better”. If anything, I’d expect slightly worse performance than esync/fsync because upstream WINE primarily wants a correct solution while the out-of-tree esync/fsync patches trade some correctness for performance in games.

    Ideally, I’d like to be proven wrong; that ntsync is both correct and performant but that’s not what you should expect going into this.

    What exactly does she need the SD card for? If she just needs to transfer files to and from an SD card, an external reader (via USB) might be sufficient.

    3.5mm jack can be substituted with an external adapter too and they’re not even half bad.

    Both suboptimal of course but small phones that don’t suck are rare enough as is.

    If size is the most important, get an a-variant Pixel.
