By that logic a battery is a generator, since it converts chemical potential energy into electricity.
Generators, as typically understood, convert mechanical energy into electricity.

The lack of exposure for this particular feature of EVs and PHEVs is kind of baffling to me. The ability to use your vehicle essentially as a UPS for your home is huge. My Outlander PHEV is capable of V2H through its CHAdeMO port but finding the equipment to actually use it seems just about impossible.
Even without special equipment though it has two 120V AC outlets and is rated for a combined output of 1500W through them. Definitely nice to have in a pinch. With a fully charged battery and full tank of gas it could run those outlets at maximum load for about a week.
That tracks with my experience as well. Literally every single Seagate drive I've owned has died, while I have decade old WDs that are still trucking along with zero errors. I decided a while back that I was never touching Seagate again.
So teaching it alongside things like the quadratic equation makes perfect sense then.
I wasn't speaking about PPPoE specifically when I made my post, all wired ethernet traffic only travels from sender to recipient without being visible to any other devices that's not in the direct communication chain. This wasn't always true. A network hub will send out incoming data to every single port, but hubs haven't been in common use for decades. A network switch is aware of what is plugged in where, and will only send received data out whichever specific port the destination is connected to. If you have three PCs plugged into a network switch and PC1 needs to send a packet to PC2, PC3 has no way of even knowing it happened.
That said, your final point is correct, and ARP spoofing defeats this. It had completely slipped my mind when I made the above post.
accessible to any device on the LAN.
Only if that traffic is using broadcasts. Wired networking on moden hardware is strictly point-to-point, PC1 is completely unaware of any traffic between PC2 and your home server or whatever.
Wireless is different and can ostensibly be snooped by anything that knows your network key, but I'd assume that you're not running services on wireless devices.
If you're doing something with the output of the engine then it's not idling, strictly speaking.
Right, but your service provider has nothing to do with that difference. The fact that the entity you're contacting on the other end of the connection is providing a degraded experience isn't an internet service delivery problem.
Your internet service, which is what net neutrality is concerned with, is distinct from services on the internet. In the same way that your phone service has nothing to do with the quality of service you get from HP's telephone support line.
Right. I'm saying both / and ÷ are ambiguous in that context. WA interprets both symbols as having equivalent meaning.
What's especially wild to me is that even the position of "it's ambiguous" gets almost as much pushback as trying to argue that one of them is universally correct.
Last time this came up it was my position that it was ambiguous and needed clarification and had someone accuse me of taking a prescriptive stance and imposing rules contrary to how things were actually being done. How asking a person what they mean or seeking clarification could possibly be prescriptive is beyond me.
Bonus points, the guy telling me I was being prescriptive was arguing vehemently that implicit multiplication having precedence was correct and to do otherwise was wrong, full stop.
...he literally used the ÷ operator in the top screenshot. WolframAlpha interprets it as synonymous with /.
Depends on the level you're viewing it from.
At a high level, yes, the purpose is basically the same as a gas tank. You put something in (electricity), and take that something back out again later. Though it differs from simple physical storage in that you get slightly less back out than what you stored.
At the level of the actual physics of the component, no. Gas goes into a tank as gas, remains gas in the tank, then come back out as (the same amount of) gas. Electricity goes into a battery, is converted into chemical potential by using that electricity to move ions from one side of the battery to the other, and comes back out by reversing that reaction. There is no electricity in a battery that isn't charging or discharging.
If instead of a chemical battery it was a mechanical spring that was wound up with an electric motor, and you extracted the power by running it in reverse as a generator from the energy of the spring, is that still storing electricity? A battery is the same, just chemical instead of physical.
