Reply to Eli5: Why can’t Google shut down Anonymous’s YouTube channel or track them and have them arrested? by thefreshlycutgrass
Google (and Alphabet by extension) can shut down their channel. That's easy enough.
As far as having them arrested, well...that's complicated. YouTube hosts servers all over the world, and not everywhere in the world has the same laws, so while Anonymous might be breaking the Las in Iran, for example, if the original poster is in South Africa, they have no agency to perform the arrest. Of course, Google doesn't have arrest power to begin with, but they couldn't even coordinate with local law enforcement. You can't be arrested for something that isn't a crime.
Next comes tracking. After all, you can't arrest someone you can't find, right? But here's the thing. "Channels" belong to individuals. Anonymous is an organization. And its an extremely dispersed organization, at that. More like a social club in terms of hierarchical organization. So, at best, each "track" leads back to one person. Shut down the channel first and you don't even have that. Then, you have to consider VPNs. If the uploaded is using one, they aren't really trackable at all (AFAIK). And given the hacker nature of the group itself, they're probably using custom-built VPNs, so the VPN provider can't help there, either. Then there's masking (assuming you can through the VPN): masking is another way to disguise your location.
And finally, because Anonymous is a group, not an individual, if you reallybwanted to het them all, the whole tracking and coordination aspects would have to be done in complete secrecy right up until the moment doors get kicked in. Assuming 1000 members in 20 countries (a conservative estimate if ever there was one), there's no way to successfully coordinate that and keep it secret. It's just not logistically or politically feasible.
And, in the end, the ultimate question: Why would they even want to try?

Well, don't forget that they also want things put away so that there is less being tossed around the cabin to injure passengers in an emergency.

Look at non-stop flights from Tokyo to Chicago (I've taken this flight a few times). Note the local departure and arrival times. The plane arrives in Chicago before it leaves Tokyo.

wow, fascinating! i didn’t know you could reduce the amount of gas. i didn’t even think about the fact that gas is being released but it makes sense

Because there have never been and never will be real studies to determine whether this is actually a dangerous thing or not. The fear is that your device emits a signal on a frequency that will interfere with flight systems and cause problems or a crash.
Starting in the early 2000s, they would make you turn off ALL electronic devices just in case and you weren't even allowed to read a personal organizer or perhaps an ebook reader. It took them 10 years or so until it was finally decided that your Bluetooth headphones weren't going to crash a plane, and now they all have WiFi on board anyway.
There may come a day when they stop caring, but for now, it's all restricted out of fear/paranoia rather than being known for sure to be a problem. As someone who has flown for decades, I have observed that many (MANY!) people have really never cared to follow these instructions and we have yet to hear of a crash being caused by electronic interference.

>The short answer is planes can't hover because they need air flowing over their wings to fly. If they were to have zero ground speed they would immediately crash.
I’m sure you already know this and were just simplifying it to make your point but planes don’t care about ground speed. It’s not super common but planes can hover if they have enough wind. It’s called perching. As you said they require airflow.
Some aircraft have a very low stall airspeed such as STOL aircraft so it doesn’t take more than about 45-50 knots of wind to start perching. In some cases they can even fly backwards lol.
Some other interesting things that happen are the transatlantic commercial flights that end up with a supersonic ground speed because of very high tailwinds in the jet stream, yet if the plane was actually supersonic it would destroy the aircraft.
Again, not bringing this up to detract from your well explained comment. I just really like planes lol.

The action of cutting onions causes a reaction between chemicals in the onion cell walls and the cells, this produces a form of sulphenic acid gas which makes your eyes water. To reduce the impact on your eyes you can either reduce the amount of gas produced or stop the gas from reaching your eyes. https://youtu.be/KYDNbM0z_RA

Dropshipping means the seller has no stock in their possession. You order from them, they turn around and order it from the manufacturer to be shipped to you.
It's good for the dropshipper because they're making a sales markup with minimal overhead costs - no need to staff or rent a warehouse if you have no stock.
It's bad for the customer because now you're waiting twice the time for two different businesses to process your order, paying a retailer markup for no good reason, and you don't even know whether the manufacturer has something in stock and ready to ship when you order from the middleman.
The only time dropshipping is good for the customer is a scenario where the manufacturer does not do direct to consumer sales, only wholesale, the dropshipper has less markup than a regular retailer, and the manufacturer actually does have the product in stock.

Just some clarification here you probably mean zero airspeed. If the wind is blowing 70mph and a plane's stall speed is 60, it could very well hover above the ground while the gauge reads 70mph.

I ask because Ive seen insects fly and sometimes hover in place, even though we are barreling down the freeway.

Yes, but when you're accelerating, the air lags behind slightly and the pressure in the rear of the car is slightly higher than the front.

During takeoff and landing is when the rules are applied and the practical reason is you need to pay attention to the flight attendants and overhead Announcememnts.

Reply to ELI5: Why do the glass panels for double glazing need to face a certain direction? What is different from one side to the other? by [deleted]
There is a special coating on the inside of the outer pane called a low-E or low emissivity coating. It is basically undetectable unless you have a low-e meter.

Nowadays your glass isn’t just glass, it has coatings on it that change its optical properties. It’ll have anti-reflection coatings between the panes, for example, and the outside face of the outside pane might have a bit of UV blocking tint on it, or something to reflect heat.

Anonymous is a loose movement of people with similar ideals. Anyone can start a channel as Anonymous. So even if you have evidence of an illegal act there is no reason to believe that the people posting videos have ever communicated with a group that is linked to a crime.

All good, I first internalized the difference for real after playing Kerbal Space Program. It starts off measuring your velocity relative to the surface, where 0 meters per second means you're not moving with respect to the ground. But get high up enough and it measures your speed by how fast you actually go around the planet, not respective of the spin. It makes a huge difference for space travel. *A geostationary satellite is traveling at some orbital velocity but its surface velocity would be zero.

It's their revenge on you for cutting them. But seriously, it's meant to deter things from eating them. Which of course is one reason we (as humans) eat them, because humans are weird and we sometimes like pain. Kinda like hot peppers, they got spicy to discourage anyone but birds (who can't taste spiciness, and are the best seed spreaders) from eating them. But that kinda backfired in the case of us weirdo humans.
