dupersaurus posted:"Discretion is the better part of valor" is pretty common among big predators (and non-predators). Just because you can gently caress something up doesn't mean it's worth the time/effort/danger to gently caress it up. i watch a lot of hawk vs. crow fights and i dont think it's about "discretion". i think one of the main reasons the hawks dont seem to fight back so much is because they can't. crows are substantially more maneuverable in the air and do all kinds of crazy poo poo that seems borderline impossible, whereas hawks are good at soaring and diving and not a lot else. while not as playful as crows, most other small birds are also a lot more maneuverable than hawks. if a hawk wanted to take out a crow or smaller bird in the air they'd have to plan some kind of "boom and zoom" type attack from a higher altitude and catch them by surprise. but the ones i've been watching, at least, are unaware of this maneuver.

Hawks and other raptors are basically brain stems with a vision processing system attached, so they don't really do a lot of thinking.

My impression has always been that hawks and the like are excellent hunters because they stick to an effective strategy that their entire biology has evolved to facilitate, but they don't accomplish much outside of that, whereas crows and the other types of birds you see in human areas are more scavengers and opportunists, which favors maneuverability and intelligence, as well as social cooperation. Kinda like a sniper versus an urban combat soldier. Pit a hawk against a crow in a wide open environment and it'll drop out of the sky and finish the crow before it knows what hit it, but in a more convined space the crow will have the advantage. A single sniper can take out a squad of regular soldier in an open field, but a bunch of solitary snipers would have trouble against a small group of coordinated soldiers equiped for urban warfare in an urban environment.

Yeah, a hawk would have to be starving or stupid to go after a crow when there are sparrows and robins (North American robins, Turdus turdus) just hanging around like dumb, comparatively sluggish little snacks.

Bears are living the good life, eating salmon and berries and poo poo, with nobody in the forest big or scary enough to gently caress with them. Why risk loving that up? No upside, best case they get to eat some different meat, worst case they get injured or killed.

I did once look up an ornithologist's take on crow-vs-hawk and other small-bird-vs-hawk fights, out of curiosity. It was just one source, and I can't find it now, but it was an "ask an ornithologist" type article. Anyway this person said that the crows are trying to discourage the hawk from hanging around their turf and it's not worth it to the hawk to fight back. They seemed to think that a motivated hawk would definitely win the fight and said "I've never seen another bird try to mess with a hawk who was nesting, for example," implying that's a time when the hawk would gently caress up anyone who got too close.

Does a smaller steak cook faster than a larger one if the thickness is the same? I assume it would, but not in a direct ratio? Like, an 8x4x1 steak wouldn’t take twice as long as a 4x4x1.

A lot of what determines who goes after who in nature is "is it worth the risk of injury" rather than "can I definitely kill it or not". Being injured in the wild essentially means death, even if you win the fight, because it'll either get infected and kill you or slow you down enough that you can't feed yourself anymore. A starving hawk with no other option would probably risk it, but a well-fed one with plenty of choices just would go for the easier prey.

For some reason hawks like to nest in the woods behind my house. The juveniles will occasionally pick fights with crows and it never seems to go well for them. Mostly because other crows will jump in but the hawks never seem to back each other up.

Like, an 8x4x1 steak wouldn’t take twice as long as a 4x4x1. Assuming a rectangular steak, and that it's being grilled with the lid open, then the surface area for heating is 32 + sf*(2*8*1 + 2*4*1) for the large steak and 16 + sf*(4*4*1) for the smaller steak, or 32+24sf vs 16+16sf (sf is the side factor for the average difference between the side heat and the bottom heat). Because the steaks are the same material and thickness, we can hand-wave the heat transfer equations as working the same for both the steaks (they don't quite because of the side heating, but that's much more effort than I want to think about - intuition says that it's a compounding effect because the the sides are further away). The cooking time is thus roughly proportional to the ratio of the volumes and heat per second, so simplifying, the ratio of cook times is something around (16+16sf)/(16+12sf), so taking sf ~ 1 you get that the large rectangular steak will take about 12% longer to cook than the same steak cut into two square pieces.

Tipping questions, US (Boston area in specific) rules apply: 1) If I go to a restaurant whose menu says something along the lines of “We add a 20% service charge, which is split among the kitchen staff and the servers, but you are also welcome to tip your server,” do I just give the server another 5%, unless they really went out of their way and inspired me to give more? 2) I went to a garden store and a child (like, a high school student) carried a 40-pound bag of topsoil across the parking lot for me because I am an arthritic old lady (I did not request this service, and in fact can carry 40 pounds easily, if that matters). Should I have tipped him? I’m not quite used to having children look at my white hair and do things for me yet.

Should I have tipped him? I’m not quite used to having children look at my white hair and do things for me yet. If it was a corporate sort of store, like a Lowes or Walmart, they would fire him if he got caught taking tips. They probably also underpay him, though, so attempting to tip a worker at such a store places them in a bad position. They probably want and would appreciate the money, but they also probably want and need their job. If you're going to do it, then don't be weird about it and make a big show of trying to offer him the money, slip it to him as quickly and as subtly as possible. But unless you're going to offer a fairly substantial amount, just don't bother.

If there's an automatic gratuity added, there's zero expectation of an additional tip. I'd even say you probably shouldn't. For the garden centre, yeah if it's a big box store it might put the kid in an awkward spot. Edit: will say that when I was a young dude working at home depot, carrying heavy stuff to cars for people was unironically one of the better parts of the job. Get some fresh air, people are usually grateful, feels good physically, etc. Trapick fucked around with this message at 02:28 on Jun 17, 2022 |

If it takes 26 minutes per 500g to cook a rolled lamb loin, that means if I had one weighing 1 kg I'd cook it for 52 minutes, right? But what if I had two, weighting 500g each, that I wanted to cook at the same time, in the same oven?

Just slip the worker some cash and don't make a big show out of it. a $10 tip pays for a nice 6-pack and getting those tips (even if they weren't technically allowed) was super nice when I worked at Lowes

Does boiling ten eggs take as long as two? I've never done more than about four at once but I always found they needed a little longer than doing them in the more usual amount of two. E: I assume once the water in the pan is boiling, it's all the same, but the amount of time required for the pan to reach boiling will be different.

The eggs will bring down the temperature so it also depends on the amount of heat you're pumping into the pot. A small burner on simmer will obviously take longer to bring the pot back to a boil than a large burner on Hi. Once it's back at a boil, bring the heat down to as low as you can while maintaining a full boil (I mean, you can just leave it on Hi but that will waste gas / electricity and money).

But what if I had two, weighting 500g each, that I wanted to cook at the same time, in the same oven? In general for meat the time should not double when you just double the weight. Since you do not increase all the dimensions by a factor of 2. On some meat packages, I often see things like "60mins for the first 1kg, then 30 mins more for each additional kg". If in doubt, ask the butcher you buy it from. See pageup for the steak discussion for a general pointer. If you have two pieces, it will depend on how much space you have between them: if they are just stuck together, the time from having one big one won't change. If they have enough space between them, the time should be similar to a single one, maybe a tiny bit longer for the absolute amount of heat needed. (i.e. this is not "one weird trick")

In the song The Happiest Girl in the Whole USA, how does moving the "bojangle" clock further from the bed allow them an extra minute? As I see it, there are two possibilities:
I first heard this song more than thirty years ago, and I have been asking myself this question ever since. How do you get an extra minute in bed by moving your clock further away?

American English never does, and Wikipedia follows the conventions of whichever dialect is local to the article. If the place is in a non-Anglophone country, it’s up to the whims of whoever writes the article first. As for whether it should be abbreviated at all, that’s more fodder for edit wars. Wikipedia’s policy is formally elaborated here and is in essence “use whatever everyone else calls it”.

This is more of a philosophical question about the nature of sentience. A computer only does what it's coded to do, and we only do what our brain circuits and chemicals tell us to do. My opinion on the matter is that it seems egotistical to only consider those programs designed to emulate human language as approaching sentience. If a text generator is sentient, then so too should be a finance spreadsheet, or a Warcraft server. In tech world, people use whatever words will get the most investor bucks, or the most article clicks. You get a lot of talk about artificial brains and AI and other sci fi things. This kinda muddies the water as to the public understanding of what machine learning systems do and how they do it. Generally, machine learning progress is about finding new ways to optimize the input and parameters of a neural network, making better training data, and most importantly, throwing exponentially increasing computational resources at it. To dispel one popular myth: These neural networks do not learn from your input. There was a training phase, but that is done now. The network is released and is static. It's just a file with a bunch of numbers in it.

For that chat bot, I don't think they ever really announced how the technology worked, but "it learned from the people it was talking to" was iirc mostly that kind of media fluff. It seemed to be a combination of the initial training data having a bunch of racism (it was collected from Twitter after all) and also it had the ability to repeat messages when asked to. My guess is they filtered the training data for slurs and then assumed that meant that it was free of racism, because that's how tech people think.

I put all my monthly spending, like groceries and gas, on my credit card. Up until last December, I've been able to pay off my card completely every month, but I bought a house and now with inflation I'm overspending slightly and carry a small balance of a couple hundred dollars month to month while still paying down 90% or so of my spending every two weeks on payday. I noticed on my credit card statements that I haven't been charged any interest despite carrying that small balance over each month. Not complaining, but I'm not sure why I'm not getting interest/finance charges. Can someone financially smarter than me explain why?

Hard to say without seeing the statement, but it sounds possible you're not really carrying the balance forward, but rather making new purchases. You don't have to be at zero to not owe anything. If you buy $500 of stuff from Jan 1-31, get a statement on Feb 3 that you need to pay by Feb 20, and in fact make $500 of payments by then but also charge a new $300, you won't owe any interest. Especially if you're making payments every payday it seems likely that's what is happening.
