  • These images, while very intricate and pretty, are not fractals, and actually show a very interesting limitation with AI nowadays. Image generation AI tools such as Stable Diffusion or Dall-E don’t actually know the meaning of the words you’re using to prompt them, they just have a pretty good idea of what sorts of things pop up if you search for those words.

    A fractal is, by mathematical definition, self-similar. You can zoom into part of the smaller detail of a fractal and find the original image, and do the same with the details in the zoomed image, and so on and so forth ad nauseum. Computers are pretty good at making these, once they’re given the rules.

    What the image generation bot has given you is an image that looks like a fractal, and that’s what it’s supposed to do. In the same way that large language models like chat-GPT will be very confidently wrong about the information it tells you, and for the same reasons, image generation AI should not be used for important topics that the prompter doesn’t already have some background information about, such as generating a map of some place the prompter has never been in preparation for a road trip.

    Thanks for coming to my TED Talk.






  • From the other side: I’m pro-union, but at my workplace I’m management.

    One of the guys on my crew is terrible at his job. Just awful. Everyone hates working with him, he doesn’t get anything done on time, he’s either stupid or willfully ignorant, the list goes on and on.

    The union, however, has negotiated that I can’t action for productivity. It literally doesn’t matter how badly he does his job, as long as he’s in his spot and something is happening, I can’t do anything. On top of that, this guy has seniority over most of the other guys on the crew, so I can’t even give him less hours without cutting the people who actually get shit done.

    It’s incredibly frustrating, and the only thing I can do is watch his attendance like a hawk in the hopes I can get rid of him for being late one too many times.



  • Says who?

    Says the diagram in the OP, the EM spectrum of a 5800K star, which clearly shows a peak within the visible spectrum in the blue band, and a significant (25% or so) drop off by the time it gets to the red band. Those aren’t relatively equal.

    As near as I can tell, your entire argument is based on what a human being perceives to be “white”, and I’m not talking about perception at all, because it lies. Examples:

    • The sky looks blue. It’s not blue, and you can tell by looking anywhere that isn’t the sky in the daytime, because the air is the same everywhere.

    • Related: the sun looks yellow. The sun looks yellow for the same reason the sky looks blue.

    • When I close my eyes, I can’t see anything. That doesn’t mean everything is black or the same color as my eyelids.

    • Your own dress example, where different people would see different colors in the same dress.

    You and I are arguing about two completely different things. You are talking about what color something looks to be, in terms of colloquial terms used to describe things people can see. I am talking about what color it is, in terms of temperature and wavelength, which are things people can measure.


  • Colors are a perception, true, which is why we don’t really talk about colors, we talk about wavelengths and temperature. 5800K is not white (relatively equal amounts of all visible light wavelengths), it’s light blue (decent amounts of most visible light wavelengths, but a significant peak in the 450-500nm wavelength band, which looks blue to us). Lightbulbs use color temperature because filament and halogen lights generate light the same way the sun does: by getting hot, and how hot it is determines the light wavelengths emitted. That’s why I included the chart, it’s a good analogue.

    If you look at the graph provided in the OP, you can see for yourself that there’s significantly more blue than anything else being emitted.


  • It’s really a pale blue. If it were white, the visible spectrum would be pretty even, but you can see the graph is higher on the blue edge and lower on the red edge. There’s enough green and red to brighten it a lot, but it’s definitely blue.

    In fact, the sun’s surface temperature is around 5800K, and you can look up what color that actually is wherever you go light bulb shopping.

    This shows the colors based on temperature, and the sun is firmly in the “Day White.” It’s called white, but you can see it’s pretty clearly blue, especially next to the “Direct Sun” color.



  • The answer is… kind of, but only really at the lower end.

    Countries with very low (around 0) electricity usage are going to be places where food refrigeration is hard to come by, if even possible, and so stockpiling and transporting food becomes more difficult. These places, then, have to grow or hunt their own food, and it’s often just enough to get by, especially considering how much hard work goes into it.

    Once electricity becomes more prevalent and food refrigeration becomes common, people tend to be a bit freer with their food consumption. This doesnt mean that they all turn into fat slobs, but it does mean that they have the the option to do so that didn’t exist before.

    Once you hit that threshold, you start to notice things spreading out on the chart, whereas there are basically no obese countries at 0 kWh, outside of a few outliers. I’m kind of curious about which countries are up there at 45% obesity rate and no electricity.



  • I can’t speak for Canada, but in the US a formal diagnosis makes it easier to get prescriptions or other treatments, such as therapy.

    As far as required disclosures, you aren’t required to disclose anything to anyone. However, disclosing a diagnosis to an employer often opens up their ability to provide accommodation. The ADA also prevents employers from discriminating based on disabilities, and ‘disability’ in this context tends to be interpreted very broadly.

    An example from real life: I am a manager at a grocery store, and one of the people on my team has some kind of ADD/ADHD/autism spectrum thing going on. It’s pretty obvious, I recognize the symptoms. However, he has not disclosed anything to me, so I have to pretend I dont see it and treat him with the same expectations as everyone else.

    If he were to come to me with a diagnosis, I can ask him how I can help him, what he needs to be able to do well, what sorts of things tend to distract him, etc.

    Once again, this is all from south of the border, though, so my takeaway would be to see if there’s any similar legislation in the Great White North.
