The question is really about why one thing is arbitrarily more popular than another, and the simple answer is that nobody knows. In the last chapter of "The Selfish Gene," Richard Dawkins introduces the idea of the "meme" which he likened to a gene, and he proposed the idea that memes vary in their characteristics, and that they compete with each other for limited mental terrain in their human hosts. Successful memes survive and reproduce by being remembered and spreading from one mind to another, while unsuccessful memes don't reproduce and die out (by being forgotten).

I'll use this evolutionary lens to address OP's question, but first I'll state that I assume that it doesn't matter which citrus you use, this cure doesn't work IRL. So why do people think the lemon-based cure works, but we never hear about similar alternatives substituting another citrus? I would expect that the belief the cure works comes from (possibly skeptical) people who try it, feel better (which would have happened anyway), and misattribute it to the "cure." Lemon would be the citrus because people probably have lemon in the house more often than other citrus. This would be simply because lemon is often added to tea and other beverages, and it's a more common garnish for food. So people believe in the lemon cure simply because they are more likely to have tried it.

If we take a step back and get a little abstract, maybe the deeper answer is that the lemon cure is more universal, so maybe memes with a "universal" quality have a survival advantage over memes with a more idiosyncratic quality.

Fun question.

Right.

I’m a volunteer fire fighter. Our captain is responsible for making a budget. It needs to be justified to the village. They base it on last years expenditures plus expected increased costs based on inflation. (Keeping it simple here because it’s ELI5, and I’m not directly involved in their budgetary planning).

They play it cautious throughout the year, in case there is something that comes up unexpectedly…if a hose blows out, or a truck breaks down…those expenses come first. But towards the end of the year, when we still have a surplus, they start buying things off the “nice to have” list, like upgraded nozzles to replace a functional but worn one. Or new PPE for the firefighters that is still within date, but a little rough. The nice thing about that, is replacing them would eventually be a need. This allows them to stay ahead of the curve year over year.

From an outsider, this may look like we spend more in the last month on frivolous things, when in fact they aren’t truly frivolous.

My company i worked for (large isp) bought all field service technicians new computers because we had to much money over If we didnt, next year they might give us a lower budget... So they spent money like crasy while looking for ways to save on other things. Like some money saving tactics were ridiculously backwards and making the job harder to do, but hey free laptops is ok. Companies are absolutely stupid

>Being much more calorie-dense, the Snickers bar would naturally result in greater weight gain

The weight you gain by eating isn't based on the weight of the food, but the calorie content. It seems like you get this concept.

The four macro nutrients in food are water, fat, carbs, and protein. However, water doesn't provide any calories for you to use. If you remove all the water from both foods, the Snickers bar is actually heavier than the cabbage.

Makes sense, no real point in mugging someone for their cards when they're just going to cancel them before you get a chance to use them anyway.

I suppose at this point muggings are probably focused on jewelry or small items they could take and sell rather than direct cash, which is probably enough work that it stops a lot of muggers from bothering.

I imagine a naive solution would be to add a gate to only cancel noises over a certain db threshold. Also you'd apply some digital signal processing to smooth incoming signal, something like a rolling average or low pass filter to avoid sudden spikes

In my experience the best case for noise cancellation is when there's a constant low level hum eg traffic or airplanes. It works wonders then. I was hesitant about getting a pair but they have been great for me (Sony WF-1000XM4)

No, you can not hear it, and that's because it's not being played into your ear, it's being laid on top of the sound that's coming into the audio device. There is no significant delay in it because there are fast dedicated chips in the sound devices that do a lot of computational work when it comes to sound waves. So, they're not always doing this in real time, sometimes they're predicting the sound before it's even completely addressed by the device. If there was a gunshot, far away, yes, it would mask it to a certain degree. That degree is what makes noise cancelling good or bad. There's a lot of other stuff that's done to facilitate the sound cancelling, one of them being plugging the ear completely so that no sound wave enter into the ear directly; no ear cavity is left unsealed. Watch THIS video and you'll be amazed to see how apparent this entire process is.

Your body has various clocks and mechanism. So various hormones such as melatonin and just stuff like temperature control your circadian rhythm.

Basically you have biological clocks that control you.

Like mechanical clocks, it's not perfect and can drift and get longer.

So your body uses things like getting bright light in the morning, exercise, meal times, lack of bright light in the evening, etc. to set and calibrate your circadian rhythm.

There are several ways to identify AI-generated comments on Reddit or any other platform. Here are a few methods you can use:

Check the language: AI-generated comments often have unusual or repetitive language patterns. They may also use words or phrases that do not make sense in the context of the discussion.

Look for patterns: AI-generated comments may be posted in large numbers and follow a similar pattern or structure.

Check the account: AI-generated comments are often posted from newly created or suspicious-looking accounts.

Use a tool: There are tools available that can analyze the content of a comment and determine if it was generated by an AI or a human. One example is the GPT Detector, which is a tool developed by OpenAI that can detect AI-generated text.

It's important to note that it can be difficult to accurately identify AI-generated comments, as the technology is constantly improving and evolving. It's also possible for humans to mimic the language patterns of AI-generated text, so it's always best to use multiple methods to verify the authenticity of a comment.

As for WHY?

There are several reasons why someone might post AI-generated comments on Reddit or any other platform. Some possible motivations include:

Spamming: AI-generated comments can be used to spam forums or other online communities with irrelevant or off-topic content.

Disinformation: AI-generated comments can be used to spread false or misleading information in an attempt to manipulate public opinion or disrupt discussions.

Advertising: AI-generated comments can be used to promote products or services in an attempt to drive traffic or sales.

Mischief: Some people may post AI-generated comments simply to cause confusion or disrupt conversations for the sake of it.

It's important to be aware of the potential for AI-generated comments and to be cautious about the content you encounter online. Always verify the authenticity of a comment before taking it at face value, and report any suspicious activity to the platform or community moderation team

American history is a constant re-definition of what "West" means. In the 1700s and early 1800s, the northwesternmost extent of the US was the Northwest Territory, which included the modern states of Ohio, Indiana, Illinois, Michigan, Wisconsin, and Minnesota.

A number of things in this area are still called "northwest", including Northwestern University near Chicago, and Northwest Airlines, which was based in Minnesota.

Of course, after the Louisiana Purchase in 1803 and the gain of the Oregon Territory in 1846, the old Northwest wasn't very northwest anymore, and so "Pacific Northwest" came to be used for the new northwest corner of the contiguous US.

>Budget is power and status; there's no reward for returning unspent money to the company.

It's not just that. We do electroplating where i work. Stuff doesn't need to be replaced on a yearly basis. And when it does need replaced, it can be very costly, especially when one thing breaks and causes other things to break. And if that budget isn't allocated to that department, it can be a very bad time until the next budget comes out. So, spending money at the end of the fiscal year, in order to use up the entire budget, on stuff that just isn't needed, can be the difference between actually getting something replaced instead of slapping some duct tape on it and hoping it'll last until the next budget.

So say you have some good ones, when the headphones hear a noise and play the inverse to cancel it, can you hear that at all? Also, is there a delay? If there was a gunshot far enough away where the headphones could manage to cover the volume of the shot, would it be able to cancel it out in real time? I just don’t understand how sound can be cancelled without some sort of other sound that plays to replace/mask it, in which case it’s not cancelling it just lessening it.
