It requires active user participation. Windows, Mac, iOS and Android will all “work” even if you have no idea what you are doing and no plans to to learn. Just keep running the apps or downloading .exes from cnet.
You can stumble your way through Linux as well but it’s a lot less forgiving. If something doesn’t work immediately it’s up to the user to search the relevant keywords and see if there is a is a fix. That can be frustrating if you aren’t so great with a search engine, you don’t know what the relevant terms are or you don’t know how to implement a fix that is not for your exact setup.
My man, my laptop sometimes turns off the screen when I tap the touchpad in Windows. It's far more broken than Linux is. Let's not go into how slow it is on an HDD in Windows 10... I have given up on booting into Windows since it's unusable
In addition to what others have said, they’re not a vacuum inside. They’re filled with 0.7 atm of argon gas. That would slow the transfer of heat, but there’d still be plenty of heat transfer through convection.
Several reasons. But I would guess a big part is that air pressure drops with altitude. 1atm is the pressure at sea level. According to my google-fu the air pressure on Mt Everest is a mere 0.33 atm.
You don't want your light bulb exploding when it breaks, especially if part of the reason you put a special gas in it was to prevent it from imploding when it breaks.
Now of course most people live significantly closer to sea level than to the peak of Mt Everest, but if a gas is heated in an enclosed space, its pressure rises.
Also, if you have to choose between shards tending to go inwards or outwards when the bulb shatters, you'd probably prefer them tending to go inwards, provided it's not so fast they shoot past the middle as they would with a much lower pressure.
Nothing really. Arch is still great, I just kept having stuff happen where I’d suddenly find out there was a new bug in something at inopportune times. Just the nature of being bleeding edge. Nothing broke severely, but like if you want to join a Zoom call or play a game with friends or something, having something break randomly that you have to fix, even if it just takes a quick search or 5 minutes of troubleshooting can get tiresome.
Also, all of the customization stuff that Arch allows is not as appealing to me anymore since my skill level with Linux has reached a point where I can get super granular with pretty much any distro. Add to that flatpak reducing my need to depend on the AUR, and there you have it.
There’s a pithy saying about science that goes, “All models are wrong, but some models are useful.”
“The food chain” isn’t a real thing, it’s just a conceptual model that humans use to organize and analyze information about the natural world. In actual, messy reality, all sorts of organisms eat other organisms all willy-nilly. We model that as “the food web”, because these phagic connections are all interlinked. I mean, mosquitoes which bite humans also get eaten by other creatures, which die and get eaten by detritovores, which build soil, and the nutrients absorbed by plants, which humans eat. Polar bears die and their bodies recycled the same way. That makes a web of connections.
As a conceptual model, “the food chain” is just a linear series of links in the food web. Picking out the start and the end is entirely arbitrary. Doing so can be useful in some scenarios, such as tracing PFAs up the food chain from polluted water to plankton, to small fish, to big fish, to bears and eagles and humans. In other cases, it’s not quite as useful, such as putting polar bears at the top of the food chain. I guess it’s useful, though, if it reminds you that polar bears are dangerous. But they mostly hunt seals, and only incidentally kill people, but people also hunt seals, and sometimes incidentally kill polar bears; the model gets complicated quickly.
Anyway, yes, humans can be below mosquitoes and polar bears on the food chain, if that’s how you decide to lay out a particular food chain.
There’s a pithy saying about science that goes, “All models are wrong, but some models are useful.”
It reminds me of something a sociology professor said about economic and sociological theories being lenses that focus on particular aspects of the world–they can’t see everything, but often they can narrow in on certain parts to aid our understanding.
The food web is directed but not acyclic, meaning that arrows can point in a loop.
An example of a directed, acyclic “web” (technically a graph), would he books being published that quote other, previously published books.
Another is (ideally) the library dependencies of a codebase. If you end up with a loop in your dependency graph your package manager will probably fail.
An example of a non-directed graph is the covid contact data that our phones were collecting if we opted in during the pandemic. If I was close to you, you were close to me. It basically means if we drew you and I as dots on paper, it would be a line connecting us not an arrow.
The food web is directed (there is the eater and the eaten) but not acyclic. I can eat a bear, and the bear can eat me, which would be represented not as one line, but as two arrows pointing to and fro.
Great explanation of the concept of a food web. Grew up only knowing the food chain as well. Still kind of fuzzy on the rules for direction with certain animal pairs and whether it’s based on predation capability or something else.
Yep saw that one and another with a deer eating a bird. So I think there’s new categories for animals now too on what they eat. Instead of carnivores, omnivores, and herbivores. There’s obligate carnivores and opportunistic carnivores. Apparently even pandas would kill for some protein if given the opportunity.
Gonna be a 3-D food web once we get all the new science rules settled.
Heat radiation in a vacuum is also an important aspect of space travel. If heat could not radiate in a vacuum, we would not be able to dump excess heat from space craft and, at some point, the combination of electric devices operating within the pressure vessel and human heat output would eventually roast the people inside. We need heat to radiate outwards, and, from my understanding, it’s actually a somewhat difficult problem to solve in a vacuum. We take air and evaporative cooling for granted sometimes when on Earth and in space, where air cooling isn’t going to happen, you have to practice other methods of heat transfer.
There’s no perfect vacuum. But as others have mentioned already, most of it is electromagnetic radiation. A very small part of this radiation is the visible light you see, most of it is invisible to the human eye.
I prefer to watch films that are good to great, no matter the time as long as the artists know how to use the time well and make the work worth to watch. There is fantastic works that span the whole spectrum, from short films to lenghy films, and there is trash all the way too (Some director compared it to paintings, that range from tiny papers to whole walls). If we really think about it, any anthology series like Black Mirror and The Twilight Zone 1959 are just a collection of short films that share a theme, some recurring stage crew, and etc. If i am short on literal time, i have no problem stopping and taking multiple sections to watch a film (purists have some point that it loses a little of the impact some times, but most of the time it really does not).
I think it is 2 reasons for the trend:
Cinema-at-home technologies just keeps getting so much better all the time, and it is already pretty great. Streaming and 80 inch 4K OLED TVs are just the latest iteration of a process started in the 1950s with tube TVs, and if VR-AR glasses popularize they will be the next. Cinema Studios and Cinema-at-theater companies had to invent new immersive technologies and art forms to stay competitive, from the rectangle screen form (16:9) until IMAX 4-D etc. They also artificially benefited the cinema-at-theater by having the release window schedule (3 months in theaters, another 6 months to dvd, 1-2 years to tv, etc), that has been diminushed but it still exists (6 weeks to 2 months in theaters i think), and in our FOMO infested culture this might make theaters stay in the long run in some form or another. But overall, home has never been such a sweet place to watch cinema.
The endless rat-race to keep cinema-at-theater competitive with cinema-at-home has eventually made that only Blockbusters in high tecnology cinemas are attractive enough to most people, and to pay for all this sensorial spectacle that ranges from the theaters to the films themselves, the scale of capital costs in the whole industry has just risen to the roof, and now the tickets are usually very expensive (and foods drinks etc). The average consumer in turn, feels that going to a film in a theater has to be WORTH it, has to be better than home and has to compensate for the high ticket (and foods etc) price. This means that films have to be a Spectacle that is highly sensorial and lasts a lot of time to become a memorable Event in the persons day, week or month. So, longer run times.
There is a cinema industry that is already more advanced in these characteristics: it’s Bollywood, with the Masala genre (i.e. a spectacle that has to please the whole family, and they include at least some romance action drama dance music in every film) and many hours of lengh (4hr is not unusual). Because the average indian is poor, and they go to the cinema rarely, so the indian studios have to make it worth it, an Event for the whole family, like Hollywood has to now. There is also something of a Music Show vibe, where the audience cheers and claps when the stars appears on screen, and actively engages with the film throughout (booing a vilain , lamenting a death scene, etc), it reminds me of the marvel spider man 3, but times 10 and all the time, it’s a cinema-at-theater experience also unmatched by home, because of the collective element. Maybe Bollywood is the mirror that Hollywood has to emulate now, instead of the other way.
All light heats up anything that absorbs it. This includes infrared, but it also includes visible light, microwaves, radio waves, etc. You can get a nasty burn from putting your hand near a live radio transmitter antenna, for example, even though it’s emitting in RF, not infrared.
In addition, all physical objects glow with a light that is determined by their temperature. This includes your body. You are, right now, emitting light. As it happens, because of your body’s temperature, that light is mostly in the infrared.
Why do kids’ science books leave you with the impression that “heat is infrared”? Because you can see body heat with an infrared camera. Infrared is light that you can’t see with your eyes — but with the right tool, you can use to see body heat. This rounds off to “heat is infrared”.
Heat is not infrared. All physical objects emit light; objects around human body temperature glow mostly in the infrared; which we can’t see with our eyes, but can see with scientific instruments. And when an object absorbs light (including infrared), it gets hotter.
If I super heat a metal and it turns visibly red what is happening? Was it already emitting infrared and as it gets hotter the frequency shifts up? Or is it still emitting infrared but has a wider band of frequencies it is emitting as well (i.e. is it emitting frequencies below infrared as well as visible red)?
Yes, as you heat something up to “red hot”, the glow shifts from infrared to being partly in visible red frequencies. This is why a blacksmith can use the color of a piece of hot iron to tell how hot it is.
(This isn’t the only way hot things make light, though — for instance, flames can glow with odd colors like green or blue due to specific chemicals burning.)
The filament is heated by electrical resistance. That heat energy comes out as photons in a wide band in the visible and infrared parts of the spectrum. Some of those photons are intercepted by the glass bulb, the metal housing, etc.; their energy heats these materials up.
Even though a vacuum prevents conduction of heat energy, it doesn’t prevent radiation of that energy in the form of photons. That’s how the light gets from the filament to the room; and that’s how the heat gets to the surface of the bulb too.
I’ve been daily driving Pop on my laptop and my biggest frustrations currently are lack of working drivers for the fingerprint reader and speakers, and the Proton VPN client is crap compared to Windows.
IIRC you can download Wireguard configs and just use it as a regular wireguard VPN. However, this limits you to the server that you picked unless you want to generate another config for a different server.
You got it all wrong, everyone is on Threads … Nah, I just subscribed to learn about starting some self hosting. I’m running a local media server, which was easy, but want to branch out to photo backup from my various phones/accounts. Getting nervous that Google will just close my account one day for no reason. Anyway, don’t fret, the community doesn’t need to be 💯 today, it’ll get there.
I personally believe reddit will live on, that’s just the way its going to be. I dropped off, but my account is still there.
To offer an alternative view: nothing! It sounds like you had a great time with the game, and it’s sometimes nice to end on a high note instead of after trudging through a bunch of side content. Besides, I’m sure you have some other games you’ve been meaning to get around to 🤔
