  • Close but not quite.

    Best translation is “I don’t want to go to work”

    Text: Kaisha ni ikitakunai

    Breakdown:

    Iku (to go) > ikitai (want to go) > ikitakunai (don’t want to go)

    In total: (To the office/workplace) (don’t want to go)

    “Didn’t have to go” might be translated as “do not have a need to go” (iku hitsuyou ga nai), so “I wish I didn’t have to go to work” might be translated as “kaisha ni iku hitsuyou ga nai to negaishimasu”

    (need to go to work) (there is not) (I pray/wish)


  • I have a sense of what you’re saying. So other comments have already pointed out the escape velocity, and those are true. But I think I can expand upon this a bit.

    So the weird thing about rocketry is that distances are insane. Like, whatever you think the distance is between 2 astronomical objects, the actual distance is probably at least 10 times that.

    This, coupled with the fact that there’s no friction in space, leads to a very unusual way of traveling. In space, if you want to go somewhere, you point your rocket in the direction that you want to go, fire the rocket up to get up to the correct speed, then just drift the rest of the way to your destination. The fact that you can just drift to different locations means that you don’t actually need to keep using up fuel for the entire trip. You only need to use fuel once, at the beginning to get to the right speed.

    In physics, this type of motion, where an object (a rocket in this case) drifts for most of the time, and suddenly changes direction in a relatively short span of time, is called impulse. So when we talk about rockets and how much “force” we need to get to places, what we’re really asking is how much impulse we need to get to the correct speed that’ll take us to where we want to go. Impulse is measured in what’s called delta-v, which is essentially a measure of “how much can we speed up.”

    There’s actually delta-v maps for the solar system. So if you want to go to this location, you need to spend this amount of delta-v to get up to the correct speed that’ll take you there. It’s an approximate map - you’ll need to do per-mission simulations to get the exact delta-v values - but it’s a good enough estimate for general usage. To use it, you start at your current location, then trace a path to where you want to go. And you just add up all the numbers that you see along the way.

    The escape velocity number is the delta-v required to leave Earth’s orbit (earth -> low earth orbit -> earth intercept)

    If you want to go to the moon, you do the same thing. Earth -> low earth orbit -> moon intercept -> low moon orbit -> moon


  • The implication is that there is a couple. The boyfriend wants the girlfriend to make out (and likely have intercourse) with another man. The girlfriend is hesitant, implying that this is entirely the boyfriend’s idea.

    Interpretation: the boyfriend has a cuckhold fetish.

    Application: any developer who uses Claude is cuckholding his own code



  • The word “nice” used to mean “stupid.” It derives from the Latin “nescio” (translated: “I don’t know”) and carried over into old French. At some point, it came to be associated with generosity, the assumption being that someone stupid is too innocent or naive to be selfish.

    It then got carried over into middle English, and the connotation for stupidity got dropped, making it so that the word meant “kind,” as opposed to “stupidly kind”



  • I don’t disagree with you, but it seems you’ve missed the point that I was trying to make. Yes, sure, the future has been predetermined in a deterministic universe. But if no person in that universe can ever figure out what that future is going to be, is there any practical distinction? To any entity within the universe, the future is completely unknown - the only thing that can be said for sure is that there is going to be a future. That is what I mean when I say that there can exist a practical free will in a deterministic universe

    In my eyes, any person who would feel dread over whether or not free will exists in a deterministic universe is splitting hairs over a thought experiment where all outcomes are practically equivalent


  • I do art from time to time. My philosophy towards art might be different from yours, so mileage may vary.

    I typically find that the sheer open endedness of creative art makes it hard to truly get into and put serious effort into, and it was only when I learned the proper techniques of drawing that creative art became more approachable. I think sometimes, people subconsciously get a bit of decision paralysis, and having a more structured approach to art helps you get into it more easily.

    If that sounds vaguely like you, then what could really help is to start off with some still life art. Just search on Google images random flowers, animal, objects, etc. Then spend around 15 minutes trying to recreate the image as accurately as possible. The trick is to pace yourself so that you don’t nitpick tiny details, but still spending enough time on it to get the sketch down accurately. This sort of practice helps build drawing technique, but also helps you develop an artistic sense for space and scale - skills that you can then apply to creative art to help it feel more structured

    Explanation:

    If you want to do gene editing, you’ll need to get your gene into your cell. Viruses are really good at doing exactly that, so a lot of modern gene editing technology revolves around putting genes into modified viruses, then infecting your cells with those modified viruses.

    As it turns out, a lot of cells also have a lot of anti-viral mechanisms. One of them is called the RNAi system. Basically, if the cell detects foreign DNA, the cell automatically assumes that that DNA is from a virus and shuts down any and all production of whatever gene happened to be in that DNA.

    This can have amusing consequences, because if you manage to trick the cell into thinking that its own genes are a virus, you can effectively block the cell from expressing its own genes. This effect was discovered when scientists tried putting a purple gene into a flower, which inadvertently caused the flower to think that its own purple gene was a virus. The end result is that the flower turned white.

    This effect turns out to be incredibly useful for scientific research, because it allows scientists to suppress any gene without needing to go through the hassle of gene editing the cell




  • It seems that the lag period (pre-Steam Deck) is causing the exponential fit to not be that good. Can you try fitting only to data from the past 4 years to see if the fit is better?

    Edit: Was easy enough for me to do, and I had the software to do it, so I did it.

    Details:

    Fitted entire dataset with a non-linear regression (minimizing sum of squares), with the given model:

    Y = baseline + Y0 * exp(k*t)

    Fitted equation was determined to be Y=0.7717 + 0.04451 * exp(0.04677 * t)

    With this fit, doubling time is 14.82 months.

    R^2 is 0.8851

    95% CI:

    baseline = 0.6029-0.9093

    Y0 = 0.01744-0.1023

    k = 0.03749-0.05734

    Doubling time = 12.09-18.49

    Edit 2: if we do a bit of the statistical funny, we can plug the equation into Desmos and try to extrapolate:

    With this data, we can estimate that Linux usage will hit a solid 5% on Steam after ~97 months (most recent datapoint is month 91 in my dataset), which should correspond to ~November 2026. If we extrapolate farther into the future, we can estimate that Linux will hit 10% at ~114 months, which corresponds to ~March 2028

    My understanding is, this is a very common cause of death among divers. The pressure doesn’t kill you, but it gets you stuck long enough that you suffocate. Because even if safety teams are notified immediately, getting you out is difficult enough that they might not be able to get you out in time before you die


  • Can’t convert INR to USD in my head, but I’m comparing costs between parts - PSU looks unusually cheap. I would typically clock a good one to be about the same price as a motherboard.

    I would double check the PSU - it’s one of those things where you really shouldn’t skimp out on.

    Edit: as another commenter pointed out as well: PSU wattage seems low. You want a wattage rating that’s about double the expected max power consumption

    You can also typically save some money by getting a non-X CPU instead of X. eg, 7600 instead of 7600X. They’re usually virtually indistinguishable in performance, but the non-X is typically much cheaper and has lower power draw (and better thermal headroom as a result).

    The 7000 series is also last gen, so you might be able to get a used CPU and save extra money there. CPU’s virtually don’t degrade (unless you actually just abuse them), so there shouldn’t be any technical concerns about getting a used CPU. Of course, watch for scams when buying used parts.
