  • How about a government-sponsored, non-profit authentication service? That is, it should be impossible to get a loan, open a line of credit, or anything else in somebody’s name, without the lending institution verifying that it’s actually on behalf of the named individual. Eliminate the security-through-obscurity technique of using bits of easily-leaked personal information as a poor substitute for actual authentication.

    I mean, (as a comparative example) I have to go through an OAuth2 consent dialog to connect a third-party app to my email account, yet somebody can saddle me with huge debts based on knowing a 9-digit number that just about everybody knows? It’s the system that’s broken, tightening up the laws on PII is just a band-aid.



  • Just spitballing here, but if I read this correctly, you pulled the Windows drive, installed Mint, and then put the Windows drive back in alongside the Mint drive? If so, that might be the issue.

    UEFI firmware looks for a special EFI partition on the boot drive, and loads the operating system’s own bootloader from there. The Windows drive has one. When you pulled the Windows drive to install Mint on another drive, Mint had to create an EFI partition on its disk to store its bootloader.

    Then, when you put the Windows disk back in, there were two EFI partitions. Perhaps the UEFI firmware was looking for the Windows bootloader in the EFI partition on the Mint disk. It would of course not find it there. In my experience, Windows recovery is utterly useless in fixing EFI boot issues.

    It’s possible to rebuild the Windows EFI bootloader files manually, but since you don’t mind blowing away both OS installs, I’d say just install Mint on the second drive while both of them are installed in the system, so the installer puts the Mint bootloader on the same EFI partition as the Windows one. With the advent of EFI, Windows will still sometimes blow away a Linux bootloader, but Linux installers are very good at installing alongside Windows. If it does get stuffed up, there’s a utility called Boot-Repair, that you can put on a USB disk, that works a lot better than Windows recovery.




  • 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 just sounds like a bad idea, a solution in search of a problem. Sure, sudo is a setuid binary, but it’s a fairly simple program, and at some point, you have to trust the code. It’s also a very fundamental piece of the system that you want to always work, even (especially!) when other things get borked. The brief description of run0 already has too many potential points of failure.




  • 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.




  • Yes, but it takes a little background to explain. Years ago, I got a delivery job at a high-end grocery. The dress code included black dress pants. I started in the height of the July heat doing physical work outdoors wearing long pants. Right away, I developed diaper rash between the cheeks, which was… unpleasant. Each day, I’d come home and get in the shower to wash my crack, and it was amazing. It felt so good, my knees would buckle, and a couple times my vision faded out. Far better than any orgasm.

    It only went on until the rash cleared, under two weeks.
