Maybe an infrared heater somewhere?
- Comment on How is my bedroom being heated? 1 day ago:
Actually yes, because “warm air” and warm solid surface" are at two different temperatures to us due to unequal heat transfer.
The walls just have to be slightly above the air temperature to heat it up, and they may feel a bit cold regardless.

Sure enough, it’s basically impossible to recreate human knowledge by checking everything yourself to see if it’s true; but something so basic really is easy to verify.
- Comment on THE EARTH IS SPHERICAL, DIPSHITS 5 days ago:
Interestingly, most of people just believe in spherical Earth without ever checking anything, because society says so.
This is not an argument in favor of flat earth, but an argument that people around you can make you firmly believe absolutely anything without you ever bothering to check it by yourself.

Penetrative sex is not the only kind. But yes, water washes lube off very quickly.

As someone who had sex in a tub/shower/all places water, it’s actually good, but not for the hot party kind of sex.
It’s a great way to get relaxed and go deep into something lovely. It’s a place for having it slow and gentle, with kisses all over and stuff like that. Also, standing on the knees, while valid for this kind of sex, can’t be maintained for long without them hurting, so, reacharound or something of the kind is the best

Some people are only in it for the initial thrill, and couldn’t care less about what it means for others.
You’ll find the one, pal, no worries. Doesn’t have to be near Valentine’s to make it a romance like no other.
- Comment on What even is fire? 1 week ago:
TL;DR Superheated products of burning in the state of plasma - essentially, an ionized gas.
Long answer:
*Boring part what causes the fire, you may skip it but it provides context
As is widely known, oxygen is the second most powerful elemental oxidizer in existence, second only to fluorine. Our atmosphere contains something like 21% of it, and nearly everything it could oxidize at our normal conditions it already did. We also use it to oxidize our food - for us, this is just breathing, but really it’s a complex set of reactions meant to essentially burn our food at low temperature.
However, one of the simplest thing that can be changed to make oxygen oxidize something else is temperature. Elevated temperatures lead to the weakening of the bonds between atoms in the molecule, making them more readily available for a chemical reaction. As a certain threshold called activation energy, the reaction (in this case rapid oxidizing, i.e. burning) starts to occur. From here on out, the heat provided by reaction is enough to heat the rest of material up to the energy required for reaction, and it becomes self-sustaining, heating further and further. The further the reaction heats up, though, the more heat it emits to the environment, and at some point, different for each fuel type and external conditions, heating and cooling of the reaction equalize at a certain temperature - typically about 600-1000°C (1100-1800°F).
Normally, when a chemical reaction occurs, bonds get so weak that atoms can leave the molecule and reconfigure in a different way - they don’t stay in this separate state for any significant time, and the outcome is always two molecules with swapped atoms. This is what happens inside our body in long chains of various reactions that involve oxygen. The end goal here is to extract as much energy as possible by putting electrons inside atoms in the most energy-efficient position, but that’s a topic for another time.
The thing is, fire works differently.
Now the part actually about the fire At such temperatures at which you see the flame, materials in the fuel don’t just swap atoms - they straight up break into free floating ions, or charged atoms, not bound to anything. They are so energized they rip chemical bonds apart. This state of matter is known as plasma, and it is very similar to gas, except gas consists of normal molecules and plasma is too hot to have that. So, in layman terms, you can see the flame as hot gas, though it wouldn’t be exactly correct.
Those ions then recombine into regular molecules, attempting to take the most energy-efficient configuration, and are moved out of the flame by the current s of air that itself gets expanded on heating. The products of this process are primarily carbon dioxide and water, as they are the most stable, energy-efficient bonds of carbon and hydrogen with oxygen, respectively.
As per why it glows - this is the property of its temperature. In fact, every object in the Universe that is above absolute zero temperature (0 degrees Kelvin, the lowest temperature there can be, signifying full stop in motion of any particles) emits electromagnetic radiation. The interactions of protons and electrons between particles form paired electric and magnetic fields. These fields radiate photons, and at the temperatures above about 500°C (950°F) the emitted electromagnetic radiation begins taking form of visible light. Due to the amounts of heated matter and the energies involved in the process, we see fire as a very bright light.
That’s it, in the nutshell :)

The point of the OP is not that we should abandon science in the name of consumerism.
It is that for-profit entities that happen to drive scientific communication put profits above all else, including, ironically, scientific communication.
Scientists should not be expected to pay the price of a car to have their articles published, that discourages sharing important discoveries where they can be noted. And the worst part - there’s nothing causing it but greed.

This kind of attack is currently hard to mitigate as it comes from different accounts and different servers. Maybe there’s a way to filter incoming messages by keywords?
Otherwise, this is just an automatic bot, you can safely ignore it.

When the house starts to fall, you can either add a support and pray it keeps going, or rebuild it all.
And the more you take the first option, the more it takes you to just keep the thing upright. At some point, a sane person says “the time has come” and rebuilds the house.
Same here. Rebuilding an entire economic system, especially when the most powerful people on Earth try to preserve it, is no easy feat - but it is a more permanent solution.

It is absolutely justified. Businesses are able to pay employees, it’s just more profitable to move that burden onto customers.
Result? Customers pay more, and workers don’t have a stable income. The only winning party is a business.
By tipping, you help the worker short-term, but aid in proliferating a system that makes it so much worse for them.
That’s why I love cultures where tipping isn’t just uncommon, but is flat out rejected, because workers are paid well and are proud of it.

I think it is the case of “you think in the right direction, but you don’t do it all the way, so now I’m gonna attack you over this until you stop doing anything”.
Not paying tips is a good start.

Also what about games?
I still vividly remember some old poor graphics racing game that featured (Gary the Snail or Turbo?) among others. The race had twists and turns, there were rocks around. I swear that was not a weird child dream!
- Comment on I am in the US and its gotten very political but as pretty much a peon do I just tune the stuff out thinking its fear mongering? Or should I closely pay attention to it? 3 weeks ago:
Depends on what you can realistically influence.
Might be worth it to tune to protest news, and also changes in your local area, if there are any.
Doomscrolling the feed will just make you continuously more obsessed with what ultimately screws your mental health to no benefit.

Here’s a really cool fact though:
In Chinese, the names of most countries are written as they sound, Russia and Belarus are no exception
Russia is 俄罗斯 (Éluósī) and Belarus is 白俄罗斯 (Bái’éluósī) - don’t ask me why they hear it the way they do, both are written as sounds with no implicit meaning.
EXCEPT
白 (Bái) not only is a sound form of Bela in Chinese, it also means “white”. White Russia, as in the original. It is both.

Oddy might be wrong in their approach to the correction, but our communications are, indeed, littered with words that are meant to emphasize something, but are instead so commonplace that they don’t mean anything anymore.
Fucking. Literally. Really. Actually. Insane. Unbelievable. Big. You name it.
In an era of everyone constantly screaming on the Internet while sitting there on the couch with zero emotions, it would make sense to step down and revisit the way we approach the language - and our experiences when facing such content.
The joke would absolutely be better off without the word “fucking”.

Nazis were not; despite taking the name of national-socialists, they only used socialism as a buzzword while acting in full interest of national bourgeoisie and promoting Germans over everyone. In fact, Nazism is reactionary in its nature and strongly opposed to any left-wing ideas.
Stalinists were left-wing, yes.
- Comment on [deleted] 5 weeks ago:
Already establishing? What does that even mean, lol
Stalin also didn’t promote national capital - aside from the fact the word “capital” does not reflect quite the same thing in the context of socialism, the policy of “socialism in a separate country” is nothing more than a reaction to the failure of world revolution. He continued international partnerships with socialist countries and participated in The Communist International.
Soviet Union did not genocide Jews and was not tied to Holocaust. The alliance with Nazis only held through the first stage of WWII as long as it was seen more as a contained European issue. It is true, however, that Soviet Union participated in occupation of Poland.

The oil prices boomed around WW2, while the highest wave of economic growth in the Soviet Union was in the 30’s.
It is Khrushchev and following leaders that benefitted from oil
- Comment on [deleted] 5 weeks ago:
Hitler took an already established economy and rearranged it towards national capital while killing Jews en masse and initiating a World War.
Not quite comparable.
- Comment on [deleted] 5 weeks ago:
Stalin is a conflicting historical figure, who is neither a monster nor a savior, and so the way you describe him would differ depending on the angle of the conversation.
If the talking point is the rights of the LGBT+ people (or, really, people’s rights overall sometimes), there’s no excuse for him there, and I’m pretty sure Hexbear is not quite the place for a homophobic rhetoric.
But they may point out in other terms that under Stalin’s rule the economy got insanely boosted, the WW2 was won, and many megaprojects used to this day were constructed.
