  • Except in social studies class. People should be aware of other people’s religions. But each religion should be taught equally, or in proportion to how many members they have. Kids should also be able to learn why people join religions and why religions are persuasive.


  • Off the top of my head, I think the best chances of survival are: C, A, B. I’m not sure about A vs. C, because A’s total odds are hard to calculate in my head, while C is exactly 1/3 (33.33%).

    The reason A is better than B is that a 1/6 chance of dying, twice, is better than a 2/6 chance of dying, once. They might seem at first like the same, but consider that one of those 36 chances in the A case is where you get shot twice in a row. That’s no worse than a regular death. So it comes out to only 11/36 of dying in the first two rounds of A, but 12/36 of dying in the first one round of B.

    spoiler

    Using a calculator. it turns out A is actually 0.16% better than C. They’re really about the same.

    The two outlets could be on different circuits, if for example one of them is connected to a switch on a lighting circuit.

    Then, the cable will be powering one circuit from the other. A circuit limited to 20A could draw 40A before blowing, causing damage to the wires.

    Someone might do some wiring work on the lights, and shut off the lighting circuit, and still get zapped (though most electricians would test it before touching it, since breaker labels are rarely accurate).

    There are many creative ways to die to a cable like this.

    But does your medical clinic do?

    No, they don’t, and it pisses me off. Every time I see it, I think, Well, there goes my medical privacy.

    But where else can I go? There’s only one health company in town, and they bought all the doctor’s offices.

    Who can I complain to? The doctors and nurses are visibly frustrated with Windows every time I see them use it. If they can’t change it, how could I?




  • You know damn well this isn’t about surgery. It’s about hormones, and it says so right there in the summary. You didn’t even have to click the link. Nobody is doing breast implants on trans minors (only on cis minors, which is perfectly fine for some reason).

    Forcing a trans kid to go through the wrong puberty even though they know they are trans is extremely traumatic. It’s life ruining. It alters the voice, the shape of the torso, the shape of the face, and facial and body hair in ways that either can’t be fixed at all, or can only be fixed with expensive surgeries later on.

    And if you want people to be absolutely sure about their status before going on hormone replacement therapy, then that is exactly what puberty blockers are for. Leuprorelin prevents puberty so that the kid can figure themself out for a year or two, and then make sure they go through the correct puberty. Even if they decide not to be transgender in the end, they can just go off leuprorelin and start puberty.




  • In my system, the raid arrays seem to do periodic data scrubbing automatically. Maybe it’s something that’s part of Debian, or maybe it’s just a default kernel setting. I don’t think it helps much with data integrity – I think it helps more just by ensuring the continued functionality of the drives.

    When it’s running, you can type cat /proc/mdstat to see the progress.

    That command will also show you if there is a failing drive, so that you can replace it.





  • Sure. First you set up a RAID5/6 array in mdadm. This is a purely software thing, which is built into the Linux kernel. It doesn’t require any hardware RAID system. If you have 3-4 drives, RAID5 is probably best, and if you have 5+ drives RAID6 is probably best.

    If your 3 blank drives are sdb1, sdc1, and sdd1, run this:

    mdadm --create --verbose /dev/md0 --level=5 -n 3 /dev/sdb1 /dev/sdc1 /dev/sdd1

    This will create a block device called /dev/md0 that you can use as if it were a single large hard drive.

    mkfs.btrfs /dev/md0

    That will make the filesystem on the block device.

    mkdir /mnt/bigraid
    mount /dev/md0 /mnt/bigraid
    

    This creates a mount point and mounts the filesystem.

    To get it to mount every time you boot, add an entry for this filesystem in /etc/fstab
