  • The only reason a trans woman would go to a gynecologist is to raise a stink. No other reason, no “healthcare” reason. I hate people who go out of their way be to a “victim”.

    “There is no recommendation for a trans woman to have regular gynaecological check-ups, unless she has a surgical problem related to the operation, because she doesn’t have a uterus or a cervix,” she added.

    Fucking drama queen.

    Seriously, what’s a gyno supposed to do? The parts they specialize in aren’t there. I can’t imagine being so pathetic that I go out of my way to cause problems for some random doctor.



  • I wanted to build a duplex but “zoning laws” say that wasn’t allowed, only single family detached houses with at least X amount of land.

    Most zoning laws are serious bullshit and work as defacto segregation to keep the dirty brown poor people away from the nice good rich folk. It’s why suburban school is a totally different things from poor urban school.

    Zoning laws are why developers in LA can’t afford to build anything other than luxury condos. Land is literally too expensive to build. As an example: a requirement to have at least X parking spots per X units, even when it’s built right next to a metro and a bus depot and you’re building low income housing for people who are less likely to own cars in the first place.

    Too many NIBYs whining about things.
















  • Hard drives are divided into partitions. Once they’re made they’re (mostly) static, it’s just a division, no other features.

    LVM (Linux Volume Manager) makes it’s own "partitions" with hookers and blackjack. Since it’s done in the OS and not on the drive it’s a LOT more flexible.

    It takes disk(s) and/or partitions and combines them into a volume group (VG) and then lets you create it’s own divisions, called [logical] volumes (LV), to split up the storage. Think of this as a “virtual hard drive” that has a TON of features.

    VGs can include multiple drives and are easy to grow or shrink, add, remove, or replace physical drives, cache another volume, encrypt, make snapshots and roll back (eg: snapshot before update, restore if update borks something). Just so much

    You can even set the RAID level for each volume! RAID controls how many copies are kept on different drives. RAID1 (or raid10) has 2 drives hold the data) for important things so even if one drive fails you still have a working copy.

    RAID0only stores it on one device. There’s RAID5 (3 copies) but it’s mostly obsolete at this point as the rebuild process is painfully slow and adds addition wear on the other drives.

    Let’s say you have 4x 4TB drives, for 16TB of raw space (raid0). Making it a raid1 would give you 8TB of space (since two copies are stored on different drives). But if you only need 1TB as a raid1 and the rest is raid0 you end up with 14TB of space left over! That’s a lot more than 8TB!

    There’s a brazillion different options and useful things it can do. Mostly I find it useful for working with raids on servers. But I’ve stated leaving a few hundred gigs on my laptop to create volumes as need, such as an encrypted volume that’s not unlocked on login to store passwords, keys, and porn tokens.



  • LVM is the Linux Volume Manager. In short it’s kind of like a partitioner inside the OS (but with lots of cool features, like encryption, snapshots and restores, and caches, RAID)

    So you add all your drives, potentially with different groups like NVME, SSD. Then in those groups you create a volume (think partition).

    Examples:

    • For example my laptop has one drive, and one volume group, but I have a separate volume for home so I can take snapshot (which are small if things haven’t changed much!) and keep my home direecty when installing a new distro. I also make a separate volume for a VM to keep my machine clean.

    • My server, however, has 2 NVME drives and 12 spinning rust drives in 3 USB enclosures. Each USB drive is set as its own VG. USB is slow though, LVM to the rescue.

    I set the rest of the space on the 1st NVME and all the space on the 2nd NVME to work as a cache for each of the external enclosures.

    Now writes are NVME speeds and it will write back to the spinning rust at USB speed. Reads from the usb enclosures if cached are at NVME If it’s in the read cache I get is at NVME speeds, otherwise it reads off the drive. At this point my read cache since creation is 82% and continuing to climb. So less than 1/5th of the reads actually went over the USB. At the rate it’s climbing the current hit rate must be in the mid to high 90s.

    A pre-seed file is basically the answers to all the questions the installer would normally ask, like how to partition the drives, what mirror to use, software to install, settings to make, etc. default user accounts, etc. Now you can run that installer on a machine and walk away until it’s done.
