  • 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.





  • Epigenetics is black magic to me. The starvation thing is true, but it mostly happens in the liver and pancreas and stuff. The testicles and ovaries don’t express the genes relating to starvation, even when starved. So how does the reproductive DNA pass on epigenetic data to the child and grandchild?


  • 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








  • Pretty fucked, but not as fucked as Ukraine, Palestine, Lebanon, or Taiwan.

    NATO will be fucked for a while if the US withdraws, but other NATO countries may ramp up military spending over time.

    This situation is a worldwide danger. The US is/was a world power, it has/had the largest national economy in the world, it has the largest military in the world.

    Previously, we could be concerned that democratic countries (including the US) weren’t putting enough pressure on authoritarian countries (like Russia, China, and North Korea) to improve. Now we have to worry that the US will actually become a fully authoritarian country, like Russia or China.


  • Any regular hex nut works just fine as a jam nut. Basically, a jam nut is when you jam two nuts together. (It is gay, because the nuts do touch.)

    And note that those nylon inserts kinda only work once. The bolt carves a thread into the insert when you insert it, so it will be weaker the second time you insert it.

    Honorable mention: cage nuts. A square nut, permanently attached to a fastener that can snap into a special square hole in a 19 inch server rack. When you tighten the bolt against the nut, it tightens against the fastener, so that the nut, bolt, and fastener are secure against the square hole.
