  • Seeking guidance on BTRFS RAID

    Jump

  • Sorry but I find this claim irreconcilable with how SLES and Fedora default to btrfs with their installations, or how a company like Meta uses it across their entire fleet.

    I don’t know if Meta uses the raid feature directly or if they use, as you suggested, mdraid with btrfs on top. I know that that’s what Synology does.

  • I’m not sure what you are suggesting as the alternative. Nor do I know what silent btrfs corruption bug you are referring to, either. Btrfs has been widely deployed in enterprise and personal environments for years, and I cannot find evidence of data loss due to the file system itself.

  • How bad of an idea is it to use computing HDDs in a DIY NAS?

    Jump

  • Absolutely correct. I used to maintain vigorous whole disk backups, and made sure my MacBook also had regular Time Machine backups and that kind of thing.

    Then I realized there are actually tiers of important data. The most important stuff would be on the order of megabytes (tax documents, my lease, historical records of that stuff, and config files that I’ve built up over time).

    Then I have my vacation photos and videos. Family photos. A few gigabytes. That’s not that much in the grand scheme and it’s still easy to back these up to a cloud service for minimal to no cost.

    The rest of the data on my computer is easily recoverable or can be reconstructed with minimal effort. The OS install. The games. Media from online. I would not bother backing up this stuff.

    Once this stuff is in perspective it’s very easy to devise a backup solution that fits your needs at an appropriate price. Not everyone has usage like mine and maybe their important data is much larger than mine is, but the point is we should think about which of the data is actually important, and not blindly duplicate pointless data.

  • three disks to get 6tb/2=3tb of available space

    Exactly! A happy outcome when using this FS.

  • My concern with ZFS is I use Fedora, so the kernel updates really frequently. I know that it kicks ass, but I just like having it straightforward in my kernel that I already have installed so that I never have to deal with a

    If kernel module can not be loaded, your kernel version might be not yet supported by OpenZFS. An option is to an LTS kernel from COPR, provided by a third-party. Use it at your own risk:

  • I was unfamiliar with single mode. What advantage does it give me over RAID0 in terms of combining their capacities?

  • That's a good point about scrubbing on RAID5. I don't think I really want to spend time on that ever. RAID1 at least sounds less complex both in terms of setup and down-the-line maintenance.

  • with three drives, raid1 doesn’t make sense

    It's perfectly usable with a btrfs setup. If one drive fails, you can mount in a degraded state.

  • In a blind test, audiophiles couldn't tell the difference between audio signals sent through copper wire, a banana, or wet mud

    Jump

  • Sadly, that basically feels like what happened with The Fellowship of the Ring's theatrical cut blu ray, too. It just doesn't look that great.

    Then the extended edition has decent fidelity but some bizarro green-blue color grading.

  • No more at the whim of specialty audio stores stock and Best Buys.

    I remember in 2017 going into an audio store near where I worked, and the guy was emphasizing how clear the audio sounded on certain (expensive) setups, and how it was streaming in from "Norway" which was better than what you'd find on Spotify or YouTube. It took me a while to piece together what he was on about.

    Dude was talking about Tidal. All he meant was they streamed lossless formats via Tidal. As if anyone could tell the difference between, say, stereo 192kbps AAC and flac.

    Also, remember the supposed amazing quality of MQA? What a shitshow. It's rather remarkable that a pair of Airpods Pro 2, when fit into your ears properly, are essentially perfectly tuned headphones for only $250 or less compared to some of what the competition sells. Not to say I don't love my Sennheiser HD650.

  • The Chinese Factory That Opened in the U.S. and Clobbered Its Rivals

    Jump

  • I was reading this article this morning and I don't know why this chamber of commerce guy's opinion isn't just the correct one

    Chris Kershner, president and CEO of the Dayton Area Chamber of Commerce, is among those who support more foreign investment from qualified nations. He is dismissive of Vitro’s complaints about Fuyao.

    “It sounds like a competitor’s just peeved that they’re losing market share,” Kershner said, “and maybe they’re grasping at straws.”

    I guess Vitro is claiming that the problem is Fuyao is exploiting illegal labor practices, but that claim only seems to even be entertained because Fuyao is a Chinese-owned company (as opposed to Vitro which is headquartered in Mexico).

  • Be glad it was merely that and not something like this https://www.reuters.com/investigations/ai-enters-operating-room-reports-arise-botched-surgeries-misidentified-body-2026-02-09/

    In 2021, a unit of healthcare giant Johnson & Johnson announced “a leap forward”: It had added artificial intelligence to a medical device used to treat chronic sinusitis, an inflammation of the sinuses...

    At least 10 people were injured between late 2021 and November 2025, according to the reports. Most allegedly involved errors in which the TruDi Navigation System misinformed surgeons about the location of their instruments while they were using them inside patients’ heads during operations.

    Cerebrospinal fluid reportedly leaked from one patient’s nose. In another reported case, a surgeon mistakenly punctured the base of a patient’s skull. In two other cases, patients each allegedly suffered strokes after a major artery was accidentally injured.

    FDA device reports may be incomplete and aren’t intended to determine causes of medical mishaps, so it’s not clear what role AI may have played in these events. The two stroke victims each filed a lawsuit in Texas alleging that the TruDi system’s AI contributed to their injuries. “The product was arguably safer before integrating changes in the software to incorporate artificial intelligence than after the software modifications were implemented,” one of the suits alleges.

  • If you want to read an article that’s optimistic about AI and healthcare, but where if you start asking too many questions it falls apart, try this one

    Because it’s clear that people are starting to use it and many times the successful outcome is it just tells you to see a doctor. And doctors are beginning to use it, but they should have the professional expertise to understand and evaluate the output. And we already know that LLMs can spout bullshit.

    For the purposes of using and relying on it, I don’t see how it is very different from gambling. You keep pulling the lever, oh excuse me I mean prompting, until you get the outcome you want.
