  • It’s mostly fluff kept for sentimental value. Worst case scenario (complete data loss) would be annoying, but I can deal with it.

    That’s one of the two things the 3-2-1 rule of thumb doesn’t address - depending on the value of the data, you need more backups, or the backup might be overkill. (The other is what you’re talking with smeg about, the reliability of each storage device in question.)

    I do have an internal hard disk drive (coincidentally 2TB)*; theoretically I could store a third copy of the backup there, it’s just ~15GiB of data anyway. However:

    • HDDs tend to be a bit less reliable than flash memory. Specially given the stick and SSD are relatively new, but the HDD is a bit older
    • since the stick is powered ~once a month (as I check if the backup needs to be updated), and I do a diff of the most important bits of the data, bit rot is not an issue
    • those sticks tend to fail more from usage than from old age.
    • Any failure affecting my computer as a while would affect both the HDD and the SSD, so the odds of dependent failure are not negligible.
    • I tend to accumulate a lot of junk in my HDD (like 490GiB of anime and shit like this), since I use it for my home LAN

    That makes the benefit of a potential new backup in the HDD fairly low, in comparison with the bother (i.e. labour and opportunity cost) of keeping yet another backup.

    *I don’t recall how much I paid for it, but checking local hardware sites a new one would be 475 reals. Or roughly 75 euros… meh, if buying a new HDD might as well use it to increase my LAN.








  • Kefka gets even better once you dig into the original dialogue, since there’s some hard-to-translate quirks on his speech.

    For example, he uses ⟨ぼくちん⟩ bokuchin as the first person pronoun, in hiragana. Typically this pronoun is only used by very young children, it feels out-of-place and creepy when an adult does it. And at the same time that ⟨ちん⟩ chin can be also understood as ⟨朕⟩, a royal we-like pronoun (Japanese emperors used it up to WW2). If you catch this early it’s pretty much a spoiler - “Kefka will backstab the current emperor and seise the power for himself”.




  • I was going to explain stuff, but given I’m verbose as fuck, it’s simply easier to link Wikipedia. A few highlights:

    sees 10 distinct colors looking at a rainbow, whereas the rest of us see only five.

    The number of distinct colours you see in the rainbow isn’t just dependent on your colour vision. I have an in-depth explanation here (up to the traffic light), but to keep it short: what you consider “distinct colours” or “hues of the same colour” is largely culture-dependent.

    Plus it depends on the rainbow itself; example here

    You’re likely to distinguish way more colours for the inner rainbow than the outer one. (For me it’s six vs. three)

    “A true tetrachromat has another type of cone in between the red and green — somewhere in the orange range — and its 100 shades theoretically would allow her to see 100 million different colors.”

    Emphasis mine. While tetrachromats are expected to have a fourth type of cone between the red and green, people with cones elsewhere wouldn’t magically become “false” tetrachromats.

    Unfortunately, in this day and age it would likely be very frustrating, especially since most tetrachromats are likely unaware of their unique abilities.

    This was written in 2001. Say hello to 2025. LEDs make this trivial - because they allow you to reliably produce light in narrow wavelengths. For example, a mix of 620nm (red) and 530nm (green) lights would be completely different from 570nm (yellow) light, even if for trichromats they’re the same type of yellow.

    To a tetrachromat, television and photography would fail to reproduce colours correctly.

    I think a good equivalent would be a TV without one of the colour channels… say, if the TV is missing the green channel it shows purple, green and grey all the same. For tetrachromats all TVs would be like this, since they’d be missing the fourth colour channel.


    Further genetic info: humans encode colour vision into the chromosomes 7 (blue opsin) and X (red and green opsins). At least in theory you could have a mutation in one of those three genes, that makes the associated cone cells absorb light in a different wavelength; and, if the person has both the mutant and ancestral alleles of the gene, at the same time, they would be tetrachromat.

    In practice this means that tetrachromacy among men is possible, but you’re far more likely to find it among women.








  • PTB.

    Sometimes, people express themselves poorly. And sometimes they hit some association they weren’t aware of. That’s clearly your case here; you were calling ChatGPT “she” instead of “it”, this screams “L2+” from a distance, and a quick glance at your profile shows you’re from Sweden.

    So why the bloody hell is the mod in question assuming racism, due to some association native English speakers in USA do???

    In that situation, they should’ve clarified that the association is seen as racist by some people. And then watch closely how you answered it; if you said something “ops, I wasn’t aware of that, my bad”, you’re probably not a racist.

    (The association between minority groups in USA and “their women is masculine” was new for me too - I’m not from USA either. Thanks ratboy@hexbear for explaining it.)
