  • Seems like the sort of thing that Nintendo will want to shut down. There are legal loopholes that can be taken to avoid copyright infringement in such cases (such as releasing a game engine without any reasources/assets a la the Super Mario 64 decompilation project), but it doesn’t look like this SM64-on-GBA project is doing anything like that. (Which is unfortunate. Other projects like the Link’s Awakening PC port that got shut down not too terribly long ago also didn’t take precautions.

    Don’t get me wrong. I hope this project sees the light of day. I just don’t think Nintendo will let it. And I wish the creators of these sorts of projects would take the necessary precautions to avoid being shut down on copyright grounds.

    But the airplane has a verifiable answer.

    That’s just the thing though. Everyone claims to have the objectively correct answer. But there’s no broad agreement as to what it is.

    If the starting force is applied to the wheels, which push off the ground, then the airplane will remain stationary.

    Is that really even an “airplane,” though? If that’s true of the hypothetical in the question, I’ve never heard it mentioned, and it seems counter to the spirit of the question.

    But if it uses jet engines or props, which push off the air, then the plane will move forward.

    But the formulation I’ve heard of it says that “the treadmill goes at exactly the same speed as the wheels rotate.” It follows that the plane cannot be moving either forward or backwards. (Assuming no slipping of the wheel against the treadmill, which I’ve heard explicitly stated in the question, If the plane is moving forward, then the wheels are necessarily rotating faster than the treadmill. If backwards, slower.)

    The versions of the question I’ve heard specify there’s no wind, so the only way I can see for that to be true is if the friction of the wheel against the axle produces sufficient backwards force on the airplane to keep it from moving forward.

    But the versions of the question I’ve heard also specify no friction between the wheel and axle. So either there’s something putting extra backwards force (I don’t want to call it “drag” because I believe that term’s usually reserved for air resistence) on the plane, which I definitely don’t think is in the spirit of the question or the question itself is nonsensical.

    So, the proper answer is neither “the plane takes off” nor “the plane does not take off.” It’s “either the question itself is self-contradictory and thus unanswerable or it leaves out important details, in which case if I’m allowed to make up more details, I can make the answer whatever I want.” (If I decide the plane is tethered to something to keep it from moving forward, the answer is almost definitely “it doesn’t take off”, unless the propellers themselves produce enough wind to create lift. If I instead decide the treadmill itself is moving “forward” (from the plane’s perspective) relative to the air, then the plane does achieve lift.)

    Or it’s possible you’ve heard a different version of the question than I have that, for instance, didn’t specify that the treadmill goes exactly the same speed as the wheels. If that’s the case, then yes, all else being equal, the plane would take off. If it instead didn’t state no friction between the wheel and the axle, I think the most reasonable answer, though one still not in the spirit of the question, would be that the plane would not take off.

    One more thing to mention. I know MythBusters tested this one and that the plane took off, but the wheels of the plane and the surface of the treadmill either didn’t go the same speed or the wheels slipped against the treadmil. (As evidenced by the fact that the plane moved forward.)



  • I honestly fully believe that proprietary software is bullshit and all software ought to be Free Software. I’m not saying I don’t use proprietary software, but I don’t trust it. If I run proprietary software, I go out of my way to try to run it in prison. I don’t let my Nintendo Switch connect to the internet except when I have a very specific reason and then I disconnect it immediately after I’m done. When I bought a robot vacuum cleaner, I bought specifically the model that I knew I could hack to not phone home. I bought a phone on which I could run LineageOS without the Google apps. (And, yes, I’m running a proprietary EFI BIOS on my main desktop machine and such. But I do take a lot of steps to limit how much influence proprietary software has on me and my devices.)



  • Yeah. I figured the day-of-the-month change should definitely happen at UTC midnight. I kindof like the idea that a day of the week lasts from before I wake up to after I go to sleep. (Or at least that there’s no changeover during business hours.)

    But hell. If you wanted to run for president of the world on a platform of reforming date/time tracking but planned for the days of the week to change at midnight UTC, I’d still vote for you.

    Note that the Sun position is not consistent throught the year and varies widely based on your latitude.

    Good call. The definitions of “noon” and “midnight” would need to be formalized a bit more, but given any line of longitude, the sun passes directly over that line of longitude “exactly” once every 24 hours. (I put “exactly” in quotes because even that isn’t quite exactly true, but we account for that kind of thing with leap seconds.) So you could base noon on something like “when the sun is directly over a point on such longitudinal line (and then round to the nearest hour).”

    Could still be a little weird near the poles, but I think that definition would still be sensical. If you’re way up north, for instance, and you’re in the summer period when the sun never sets, you still just figure out your longitude and figure when the sun passes directly over some point on that longitudinal line.

    Though in practice, I’d suspect the area right around the poles would pretty much just need to just decide on something and go with it so they don’t end up having to do calculations to figure out whether it’s “afternoon” or “morning” every time they move a few feet. Heh. (Not that a lot of folks spend a lot of time that close to the poles.) Maybe they’d just decide arbitrarily that the current day of the week and period of the day are whatever they currently are in Greenwich. Or maybe even abandon the use og day of the week and period of the day all together.

    Just the days of the week? you mean that 2024-06-30 23:59 and 2024-07-01 00:01 can both be the same weekday and at the same time be different days? Would the definition of “day” be different based on whether you are talking about “day of the week” vs “universal day”?

    Yup.

    I’m just thinking about things like scheduling dentist appointments at my local dentist. I’d think it would be less confusing for ordinary local interactions like that if we could say “next Wednesday at 20:00” rather than having to keep track of the fact that depending what period of the day it is (relative to landmarks like “dinner time” or “midmorning”) it may be a different day of the week.

    And it’s not like there aren’t awkward mismatches beteen days of the week and days of the month now. Months don’t always start on the first day of the week, for instance. (Hell. We don’t even agree on what the first day of the week is.) “Weeks” are an artifact of lunar calendars. (And, to be fair, so are months.)

    (And while we’re on the topic of months, we should have 13 of 'em. 12 of length 30 each and one at the end of 5 days or on leap years 6 days. And they should be called “first month”, “second month”, “third month”, etc. None of this “for weird historical reasons, October is the 10th month, even though the prefix ‘oct’ would seem to indicate it should be the 8th” bs. Lol.)


  • I think having a way to delete accounts is legally required by some jurisdictions. And sometimes if a site does business in such a jurisdiction and are required to have a way to do that, they’ll still offer that option those outside the jurisdictions in question. (It’s easier to just allow everyone who asks than to have rules keeping track of who can and can’t legally demand it.)

    But if this is an image board hosted in Japan intended for a Japanese audience, and if Japan has no such legal requirements (or if such requirements don’t apply here for some reason), then, your experience with websites that operate in/for countries where they speak your language(s) notwithstanding, it’s highly plausible this site just doesn’t have any way to delete accounts.


  • Your concern is that a breach of the site’s data may leak some information about you that you wouldn’t want to leak, yes?

    If so, and if you can still use similar methods to navigate the site in question, use those methods to edit your account/profile details to scrub the account of anything that you wouldn’t want to leak. Change it to use a fake name. Change the email address to somthrowaway email address. Change the password to something unrelated to any passwords you could possibly use on any other sites so that if the hash is leaked and brute forced, no one can use that to gain access to any of your other accounts. Delete individual posts or pieces of content that you’ve uploaded.

    Actually, I can read (barely) enough Japanese to figure out that the registration process seems to only want your email address and password. (Though I haven’t gone through the whole signup process.) You mentioned uploading a file, yeah? I’m guessing the amount of stuff you’d have to do to overwrite/delete every bit of data they have on you is pretty limited.

    And, yes, I suppose there’s the potential caveat that that might not affect backups and such, but I’d wager a lot of the other account deletion requests you’ve done don’t affect things like backups either.

    No, see, how it would work without timezones is:

    • Everyone would use UTC and a 24-hour clock rather than AM/PM.
    • If that means you eat breakfast at 1400 hours and go to bed around 400 hours and that the sun is directly overhead at 1700 hours (or something more random like 1737), fine. (Better than fine, actually!)
    • Every area keeps track of what time of day daily events (like meals, when school starts or lets out, etc) happen. Though I think generally rounding to the nearest whole hour or, maybe in some cases, half hour makes the most sense. (And it’s not even like everyone in the same area keeps the same schedule as it is now.)
    • You still call the period before when the sun is directly overhead “morning” and the period after “afternoon” and similarly with “evening”, “night”, “dawn”, “noon”, “midnight” etc.
    • One caveat is that with this approach, the day-of-the-month change (when we switch from the 29th of the month to the 30th, for instance) happens at different times of the day (like, in the above example it would be close to 1900 hours) for different people. Oh well. People will get used to it. But I think it still makes the most sense to decide that the days of the week (“Monday”, “Tuesday”, etc) last from whatever time “midnight” is locally to the following midnight, again probably rounding to the nearest whole hour. (Now, you might be thinking "yeah, but that’s just timezones again. But consider those timezones. The way you’d figure out what day of the week it was would involve taking the longitude and rounding. Much simpler than having to keep a whole-ass database of all the data about all the different timezones. And it would only come into play when having to decide when the day of the week changes over.)
    • Though, one more caveat. If you do that, then there has to be a longitudinal line where it’s always a different day of the week on one side than it is just on the other side. But that’s already the case today, so not really a drawback relative to what we have today.

    The creator of DST gets the first slap. Then the timezones asshole.

    I’m planning to do a presentation at work on how to deal with dates/times/timezones/conversion/etc in the next few weeks some time. I figure it would be a good topic to cover. I’m going to start my talk by saying “first, imagine there is no such thing as timezones or DST.” And then build on that.




  • From the content of this thread, I’m betting there’s a lot of selection bias going on. The ones who don’t scroll past. The ones who do post.

    And I’ll follow that pattern. I still live with my mother. Never moved out. Live in the same house I was raised in. But my mother was never really financially stable. My grandmother with whom my mother and I lived… well, she managed to keep us housed and fed with credit card debt, which honestly worked out very well.

    Anyway, I was kindof the only person who really made much of an income in my household and have been financially supporting my parents for decades now. (Though my grandmother passed on a few years back and left me a life insurance policy.)

    I’m 37 now.
