  • Are you referring to Method of Loci? I’ve experimented with it a bit. For a while I would do daily mental walk-throughs of the apartment I grew up in and I practiced visualizing symbols for the 10 digits. After a few months I was able to successfully remember some pretty long numbers. Ironically, I don’t remember how long they were. It wasn’t that useful though. It took me a really long time to “store” numbers; longer than it would to just write it down. I didn’t have a system for storing anything besides digits. Worst of all, the “memory space” was limited to the size of my old apartment. I was able to increase the space by adding detail to rooms but it was never enough to be practical for anything besides trivia. Strangely the repeated “walk-throughs” ended up bringing back memories of smells and textures that I hadn’t thought about in decades

    I think I’m much better at remembering and imaging things that can be easily articulated. I recognize my wife with no problem but I can’t really summon a good mental image of her. We have a photo of the night we met. I can visualize details of the clothing and jewelry she was wearing but when I “look” at the image in my mind I can’t really see her face. It’s hard to describe. Almost like there’s an image with a tag that says “link to wife’s face here” without actually loading it. When I really concentrate on it I can wither get a really blurry image of her face, a really zoomed in image, or a sort of “line art” version of her face. I don’t have real prosopagnosia. I can recognize faces, it just takes many more exposures than it does for most people.



  • This (and the human brain in general) is fascinating to me. I’ve always been on the opposite end of aphantasia, although I’ve never been officially diagnosed with hyperphantasia. I don’t understand it at all it just seems natural.

    When there’s a question about physical objects I close my eyes and just check. It’s not that my memory is particularly good but I can “synthesize” shapes. I might tell myself a story like, "Start with a point. Expand it into a line segment. Now pull that line parallel to itself to create a rectangle. You can spin that plane around a bit and then grab a point in the middle and pull it up into a pyramid. And so on. I basically watch a color-coded animation when I say something like that.

    With music it can be a bit distracting. I’ll go through phases where I get some piece of music stuck in my head and when I do it’s incredibly detailed. I can pick out individual instruments in an orchestra and hear reverb. It can actually get so distracting that I have to play a trick to get it to stop. I need to find a piece of interesting music that I’ve never heard before. I can play that enough times to “drive out” the other one but not enough to “light up” the new one and I’m fine.

    As a kid it was obvious that this was not something everyone did and I thought I was special. It turns out that beyond being an interesting curiosity I haven’t found any actual use for it. Too bad. I still find these differences really interesting.

    As an aside, I’m also one of those people that’s terrible at remembering names and faces. I often completely forget someone’s name and face within minutes of meeting them. I’ve started using Anki to help with it. I make flashcards of all the people I’m supposed to know and run through them every night. It’s a hack that works well enough that (some) people think I’m one of those people that never forgets a face.


  • The thing with symbols is that they don’t have have objective meanings. Their meanings are entirely a matter of interpretation and they’re incredibly fluid.

    Necklaces can also be symbols of oppression. Chains, in general are far more commonly used as symbols of oppression than any article of clothing. There’s the obvious association with collars that are used to control slaves and livestock. There is also slavery symbolism associated with ankle and wrist bracelets, largely due to their similarity to shackles.

    The ultimate test is what the individual thinks of it. If we’re forbidding a girl from wearing some article of clothing that she wants to wear, we’re the oppressors. If we’re truly worried about some situation where parents are forcing their children to wear some clothing a more appropriate response would be to either ban all religious clothing or to adopt a policy of clothing choice being a protected privacy matter and barring schools from discussing a student’s clothing choices with their parents.

    From the evidence I’ve seen, this policy is less about protecting the rights of girls and more about using that as a rationalization to marginalize Muslims.


  • Is that intended as a legal or moral position?

    As far as I know, the law doesn’t care much if you make money off of IP violations. There are many cases of individuals getting hefty fines for both the personal use and free distribution of IP. I think if there is commercial use of IP the profits are forfeit to the IP holder. I’m not a lawyer though, so don’t bank on that.

    There’s still the initial question too. At present, we let the courts decide if the usage, whether profitable or not, meets the standard of IP violation. Artists routinely take inspiration from one another and sometimes they take it too far. Why should we assume that AI automatically takes it too far and always meets the standard of IP violation?


  • Yes but there’s a threshold of how much you need to copy before it’s an IP violation.

    Copying a single word is usually only enough if it’s a neologism.
    Two matching words in a row usually isn’t enough either.
    At some point it is enough though and it’s not clear what that point is.

    On the other hand it can still be considered an IP violation if there are no exact word matches but it seems sufficiently similar.

    Until now we’ve basically asked courts to step in and decide where the line should be on a case by case basis.

    We never set the level of allowable copying to 0, we set it to “reasonable”. In theory it’s supposed to be at a level that’s sufficient to, “promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.” (US Constitution, Article I, Section 8, Clause 8).

    Why is it that with AI we take the extreme position of thinking that an AI that makes use of any information from humans should automatically be considered to be in violation of IP law?


  • Slashing is overrated. They’re less likely to connect because they’re slower and easier to see (it’s easier for humans to detect movements across your vision than movement directly toward you). They also have less effect since the force is spread out over a larger area. Yes, you can generate huge forces in a swing if you really wind up and hit with just the right part of the weapon or tool but that haymaker is never going to connect against an opponent who’s still awake.

    The big advantage of slashing is that it’s easier. It’s the simple dumb response when you had someone a heavy thing. It also often works better than just using your fist or dropping the weapon all together but it’s generally not the best way to use a weapon.

    And yes, there are exceptions. Slashing with knives and one handed sticks can be extremely effective. But even with those, stabbing tends to be at least as effective and all these effects are exasperated with larger weapons. Just take a metal bar the size of big sword and swing it at a tree. Then see how many times you could poke that tree in the same time.




  • It occurs to me that there are several species of animals that have both claws and anuses, and that like to eat breadcrumbs. They will bring their claws and anuses with them when they partake in a feast and aren’t particularly careful about them.

    Permanent markers, grease pens and crayons write on glass. Windshields are made of glass. What a coincidence.

    I’m not talking about any particular language.

    Modern programming languages are as complex as natural languages. They have sophisticated and flexible grammars. They have huge vocabularies. They’re rich enough that individual projects will have a particular “style”. Programming languages tend to emphasize the imperative and the interrogative over the indicative but they’re all there.

    Most programming languages have a few common elements:
    Some way to remember things
    Some way to repeat sets of instructions
    Some way to tell the user what it’s done
    Some way to make decisions (ie if X then do Y)

    Programmers mix and match those and, depending on the skill of the people involved, end up with Shakespear, Bulwer-Lytton, or something in between.

    The essence of programming is to arrange those elements into a configuration that does something useful for you. It’s going to be hard to know what kinds of useful things you can do if you’re completely fresh to the field.

    Python and Javascript are great. The main reasons I wouldn’t recommend them for an absolute beginner is that it takes some time to set up and, even after that, there’s a bit of a curve before you can do something interesting.
    If they go and change configuration settings in an app, they’re learning to manipulate variables.
    If they click a “do this N times” they’ve learned to create a loop.
    etc.


  • I’d actually start by playing around with the automation and customization functionality you already have. Learn to set email sorting filters, get some cool browser extensions and configure them, maybe even start by customizing your windows preferences or making some red stone stuff in Minecraft.

    Computers are just tools. Programs are just stuff you tell a computer to do over and over again. All the fancy programming languages give you really good control over how you talk to a computer but I’d start with the computer equivalent of “Me Tarzan, you Jane.”



  • Insurance can work just fine for things like hurricanes. Insurance companies have several methods to address it. They’re all effectively variations of buying insurance policies themselves.

    Re-insurance pools are a close analog. It’s basically a bunch of insurance companies from around the planet getting together and agreeing to pool risks. Big companies also use a bunch of funky financial instruments to simulate insurance.

    There’s some risk of increased systemic correlation (eg climate change may increase the risk that major hurricanes hit multiple areas around the planet simultaneously). That’s largely mitigated in that we can see it coming. Climate change is pretty prominent in their models and they can adjust premiums or stop offering policies, over time.

    The bigger risk is in synthetic systemic risk. It’s burned us a bunch of times already and it’s gonna do it again. Those giant global re-insurance pools are almost certainly fine, and worth the risk, if we just use them for their intended purpose. But history shows that we’ll end up creating derivatives contracts on them and those contracts will get leveraged. Those leveraged pools end up merging and turning into giant financial time bombs.


  • This is a difficult question. I try to focus on the article itself rather than the news site.

    The first thing I look for is if they’re rambling. That’s probably not the best criterion but it’s so obvious. If an article doesn’t get to the point in the first few sentences it probably doesn’t have a point.

    The second thing I look for is verification. I already know some stuff about the world. If know the article made some mistakes I’ll assume they’re making other mistakes. If they are correct about less well known facts I mentally bump up their reliability a bit.

    If they make a statement about a fact I expect them to source it. If their source is some equivalent of “trust me bro” I’m getting out my salt shovel.

    Beyond that I’ll look at the track record of the author and the publication. Do they consistently pass or fall short of the reliable news threshold? If so, I adjust my expectations.

    The individual articles or statements come first though. I may have very little confidence in Fox and Friends or in Donald Trump but if they get on TV and make independently verifiable statements that check out then it’s true.

    In terms of a simple rule that could be practically implemented. Maybe something like, the article must have independently verifiable sources for its claims. One corollary would be, if article A cites article B as a source, don’t post A, just post B directly.

    It would be great if there could be some discussion of what exactly “diversity” means. It’s one of those words that people seem to assume is well defined but I can’t get anyone to define it.

    I don’t know what the definition should be but I’ve seen variations that assume different definitions and I’m more comfortable with some than with others.

    1. I have a friend who works at a bank. He bragged that his team was 100% diverse. When I asked him what that mean he said there were no white people on his team. Personally, this seems like a bad definition. I have trouble thinking of “diversity” as the removal of some group, even if that group is otherwise over-represented elsewhere. It also ignores any potential diversity around any other factors; either the traditional political factors such as gender or religion or any diversity of thought (do their analysts include both Frequentists and Baysians?)

    2. Reddit mostly has users from the US. Should we consider a Lemmy community diverse if it represents the predominant views and voices of the US? If that’s the case the image above needs more white people. https://en.wikipedia.org/wiki/Demographics_of_the_United_States#Race_and_ethnicity

    3. The world is a big place and anyone could join Lemmy. Should we consider a community diverse if it matches the demographics of the planet? In that case the image above has too many white people. https://en.wikipedia.org/wiki/World_population#Global_demographics

    The above focuses on race but it’s more widely applicable. This community will most likely consists of mostly US citizens for the near future. If the community is firmly focused on US ideas it will be more about US opinion of the rest of the world than actual diversity. If it actually does include a globally diverse set of ideas it’s likely to get pretty uncomfortable for the majority of the people here.
