  • This is madness, but since this is a hobby project and not a production server, there is a way:

    • Shrink the filesystems on the existing disks to free up as much space as possible, and shrink their partitions.
    • Add a new partition to each of the three disks, and make a RAID5 volume from those partitions.
    • Move as many files as possible to the new RAID5 volume to free up space in the old filesystems.
    • Shrink the old filesystems/partitions again.
    • Expand each RAID component partition one at a time by removing it from the array, resizing it into the empty space, and re-adding it to the array, giving plenty of time for the array to rebuild.
    • Move files, shrink the old partitions, and expand the new array partitions as many times as needed until all the files are moved.

    This could take several days to accomplish, because of the RAID5 rebuild times. The less free space, the more iterations and the longer it will take.






  • This is an infuriating aspect of this case. The courts could have held the clinic responsible for this loss without declaring that all frozen embryos are children by invoking the “prime mover” concept. Other courts have used it in, for example, surrogacy cases. In short, that concept holds that it’s the intent of the parent(s) that matters, as the prime movers in the process of bringing a child into the world, not just the mixing of some genetic material. Those destroyed embryos could have become children, as it was the parents’ intention to do so. And if nobody intends to implant embryos, for whatever reason, without the intent to make a child, they’re merely organic material, neatly sidestepping those questions.

    But, of course, the court wanted to impose its religious orthodoxy rather than issue a sensible ruling. Now we have those thorny questions.



  • I don’t know about theory, but the big practical advantage to ZigBee is that it works.

    Sorry, that’s a shitty thing to say. I’m salty because the only time I tried X10 was 25 years ago, and the experience was less than great. Unreliable switching, spurious commands, slow performance, etc. Sending signals over the power wires sounds great in theory, but in practice there are all sorts of pitfalls, like resistive versus inductive loads, bridging circuits to different legs of two-phase power, or conflicting commands on the wire.

    ZigBee has just worked for me, since it avoids all of the potential wiring issues. You just plug a device in, put it in pairing mode, and Home Assistant finds it, interrogates its capabilities, and adds it (by name) with the correct entities. No mucking about with addresses, or adding signal paths to the house wiring. As a mesh network, it’s quite robust, since most plugged-in devices act as repeaters.

    The downside of ZigBee, of course, is that it may not work well in WiFi-saturated environments, since it uses the same 2.4GHz frequency band.



  • For troubleshooting, start at the destination and work back. Run a packet trace on the target machine, and other machines on the WiFi network to see if any WoL packet comes through at all. If not, then look at the VM host.

    How does HAOS access the USB network adapter? By pass-thru, so it’s like a USB device connected to the VM, or through a bridge on the VM host? If it’s the latter, a Linux network bridge device is often configured not to pass broadcast packets by the firewall rules. (Things like Docker will enable firewall filtering.) Check that the bridge allows broadcast packets through. If it’s the former, the USB pass-thru, do a packet trace from HAOS to ensure that it’s actually sending the packet, I guess.







  • I worked in retail grocery, but I would imagine the situation is the same in other retail outlets. Everybody who has replied so far has a piece of the answer. Sometimes the sale item is a “loss leader,” sold below cost to bring customers to the store, where they’ll buy other products at the same time. Sometimes the price is jacked up before putting it on sale to hide a price increase, or take advantage of the anchoring effect. Sometimes stores take a loss on a product that isn’t selling well, and they just want to get rid of it to free up space. And sometimes the store’s buyers got a really good deal on purchasing inventory, for many possible reasons, like a bulk purchase, supplier clearing the warehouse, or pre-booking the order well in advance. (Manufacturers often give discounts for guaranteed purchases.)

    But, yes, as you suspect, sometimes the markup is outrageously high, and they can still make a profit when offering 50% off. (Not often in grocery, which is a low-margin business.)




  • Certainly, I just phrased it that way as a lead-in to saying that B5 does definitely get to excitement, and is better for all the buildup. I watched it when it first came out, so at the time we had ST:TNG wrapping up, and only B5 and ST:DS9 as sci-fi on TV. That is to say, we were patient with both shows, because there wasn’t much else (good) to choose from.

    Nowadays, there are more sci-fi shows than I can keep track of, so even though B5 is my all-time favorite, I recognize that it may not be as good (too slow?) for first-time viewers as newer shows which benefit from a couple of decades of improvement in TV production.

    (The Expanse is definitely in my queue. Just need the time to get to it!)
