  1. You're using an engine to decelrate, which is called engine braking. It doesn't matter if it's an electrical engine or a combustion engine. You're assuming that you could somehow increase engine braking to compensate for a higher power output of the engine, assuming that it actually matters. I didn't give a definition. You're talking about energy, I'm talking about power. You simply need more braking power when you want to decelrate faster, and you need more power when you want to accelerate faster. I can't do math so I won't even try to show you the formulas; I only know that twice the acceleration requires four times the power, and it doesn't matter if the acceleration is one way or the other, i. e. twice the deceleration also requires four times as much braking power. Prove me wrong if you can. In any case, you have to have brakes that can handle the performance, and that means that the manufacturer needs to put those into the car, which costs more than weaker brakes. Now when you look back at the start of the thread, we seem to be talking about a car rated 400HP and when you give in to the extortion, you get an increase of 20--60%. That means you have up to 640HP, and you're telling me that Mercedes puts 400HP brakes into a 650HP car because engine braking could compensate for it. Mercedes builds some crap and some good stuff, just like other manufacturers do, but I do not believe that they skimp on the brakes like that. Do you have proof that Mercedes puts undersized brakes into the car so that buyers don't have to pay as much? Assuming that engine braking could compensate, you need to explain why they would limit the engine braking unless you give in to extortion so that you get more of that as well in order to compensate. Or is it more likely that they use as much engine braking as reasonably possible to regain as much electricity as they can all the time? People are usually very concerned about range since the range of electric cars is miserable, because it's difficult to find a place to refill, and refilling takes ages, so foregoing a longer range by limiting engine braking would seem like a very bad move. If they do limit engine braking as well, well, then that all the more means that they punish their customers for buying a way overengineered car they pay a ton of money for while the car doesn't come close to the performance they payed for unless they give in to extortion. So their intention is to make sure that there are fully working brakes since there isn't much electricity from engine braking you could put into the batteries when they are full. Mercedes can't just skimp out on the brakes, not even in Canada. As a buyer, you'll have to pay for brakes that can handle 640HP. How much does the thing weigh? About two metric tons, maybe 2.5 when loaded? I'm pretty sure that brakes that can savely handle a 2.5 ton vehicle with 640HP which is (I'm assuming) governed to max 250km/h aint cheap and that they are more expensive than brakes designed for only 400HP --- which aint cheap, either. Of course it's the same vehicle. It has been designed for 640HP and that's what the buyers pay for, not the 400HP they get.
  2. I'm unfamiliar with those, is m.2 and nvme the same? If I wanted to get an PCI adapter card that holds at least two of these things, or better more, and works well with Linux (and software RAID), what I should I be looking for? Apparently these things can get hot? And I might want to boot from them.
  3. Get a new monitor before it doesn't work at all anymore?

  5. https://www.merriam-webster.com/dictionary/engine "a machine for converting any of various forms of energy into mechanical force and motion" https://www.thefreedictionary.com/engine "A machine that converts energy into mechanical force or motion." https://www.wordnik.com/words/engine "A machine that converts energy into mechanical force or motion." https://www.dictionary.com/browse/engine "a machine for converting thermal energy into mechanical energy or power to produce force and motion." 4/4 of dictionaries agree that an engine converts energy into mechanical force/motion while only 1/4 of them brings thermal energy into play. When you convert thermal energy into electricity and use it to power an electrical engine, the electrical engine runs as much on thermal engery as a combustion engine. You can use a pump to drive a boat, and when you do that, it kinda becomes part of the engine that drives the pump that drives the boat ... I leave it up to you to look up what dictionaries say what a motor is. It's something like this: https://www.dictionary.com/browse/motor "a comparatively small and powerful engine, especially an internal-combustion engine in an automobile, motorboat, or the like."
  6. Why does the graphic show well over 100000 cycles for when you keep the battery at 10% discharge while the table says it lasts only about 500? Going by that, it would be best to leave the phone plugged in all the time. I've done that and it destroyed the battery, so I don't believe these numbers.
  7. For all I know whoever asks such a question has a problem with a lack of intelligence, and if the code solves it for them is only for them to decide.
  8. That you think so doesn't mean it's true. Different manufacturers have different levels of prices for spare parts. That only works as long as you can get aftermarket parts that are of sufficient quality. If you get that quality, the prices aren't always lower. 2002 is already modern. We're not supposed to have cars anymore, and they have been made more expensive for over 30 years now.
  9. They are electrical engines. You can call them motors when you want to, it doesn't make a difference. Show me the EC law where it says that it's sufficient to overcome the torque. And read up on physics, 5 vs. 10 seconds means four times as much energy, and you do need better brakes to accomplish that. Designing the car for more power, even when withheld, also very likely means that it weighs more, and thus you also need better brakes that can handle the extra weight.
  10. From what I've been reading, fast charging reduces battery life. Only 4 years is nothing.
  11. There are very few examples; usually it doesn't. When it doesn't and you do it, the computer may turn on unexpectedly when you forgot to unplug the power cable. So no, you can't just switch ... This is a mysterious situation with a very far fetched idea. A simple mechanical solution would be to take one card out and plug another one in, thereby sooner or later wearing out the contacts. That doesn't seem to be wanted. Using relais might work with hotpluggable PCI, but will that create a reliable connection? And what if one of the relais hangs, you wanna debug that?
  12. PCI isn't hot-pluggable, so you can't just switch. You need to forget about putting it all together into one thing and find a more feasible approach.
  13. And how long is the battery gona last like that? Who makes docking stations for cell phones? Sure there is, and it's fashionable to ignore reality and facts in favour of ones points of view. Sooner or later, reality will catch up.
  14. Then you're going to the wrong dealership. And if you really do own two cars, you probably know that they made it so that you can't get around going to the dealership for anything more than an oilchange or new brake pads (if you're lucky) because an arbitrary place doesn't have the required testing equipment and doesn't have the special tools they need. And what do you think where the spare parts come from.
  15. Sure it's fact, it's what Mercedes does. It's not like they build a car like that and sell it to people and then they suddenly discover that they can increase power considerably if only people keep paying for it. They must have planned it from the beginning and designed it that way and have buyers pay for it and now they make them pay extra for what they already own and payed for. You can call it extortion or leeching or whatever. If you like it enough you'd probably wouldn't think so. Or if you have enough money that it doesn't matter to you it doesn't matter.
  16. You have no idea what you're talking about. Talk to some people who do 1/4 mile races maybe and let them explain a thing or two about energy.
  17. Sure he was. He was promised to get refunded, which would have made him unbuy the cooler, but the promise wasn't kept, so he had no choice. Shrugs ... Ask him what he payed for. Ask a BWM dealer, they will tell you their cars last only 3 years. Where do you get 15 years from?
  18. He payed for the cooler and was supposed to be refunded after it turned out to be crap, and instead he got a cooler. Since he couldn't do anything about it, he was forced to buy one. Just because someone would buy something doesn't meant it should be manufactured. And when you do manufacture something, then do it right. Then they need to be built better. Obviously you entirely missed the point then.
  19. Getting another cooler instead of the refund could be seen as being forced to buy another cooler, especially since the sender refuses to arrange the pickup. The OP doesn't seem to answer here anymore, so we won't find out. If AIOs are diposable as you claim, they shouldn't be manufactured in the first place so the resources wasted to produce trash could instead have been used to make something that lasts. Does the manufacturer tell you that they are selling you trash before you buy one?
  20. So you are saying that the OP is lying. Do you have any proof of that? I'm not arguing for anyone but for what is right. And I have had a similar thing happen, so I know how these scammers work. Just wait until it happens to you and the we'll see how you like it.

Huh? Why would you ever give your data out of hands?? You'd at least have to encrypt everything with GPG before uploading, and that makes it even more unwieldy to backup over the internet. > Backing up everything including connected devices was a hypothetical > idea Having backups isn't a hypothetical idea but a requirement. > Some time ago I heard of people talking about doing daily full > backups and hourly incremental/differential backups, but with my > mutliple 10s of TBs (actually now probably >100TB) capacity, that > doesn't seem possible.

You need a 19" case. When electricity is that expensive, you can run your server only when you're using it, so you need to distinguish between active data and archived data. > Actually, SATA does include hot-plug ability in the spec, at least > for internal SATA I think.

Yes, but have you ever seen it in practise? eSATA requires special plugs that make sure that the wires are dis-/connected in the right order, and who uses those. > Also I would want to be careful to not eject a disk Huh?

Just consider how long it takes to write a 40MB file now and how long it took when entire disks were 40MB small.

Any board and/or SATA controller or whatever can fail and damage your data. That's one of the reasons for having backups.

  22. This isn't a joke. I have a bunch of C13/C14 cables and it's fine when I don't get more. I also have some VGA and HDMI cables and don't need more (though I might a new HDMI cable because HDMI changed over time and the cable I have might not work, but I don't know). Graphics cards don't come with cables. Dishwashers and laundry machines usally have cables attached, perhaps because C13/C14 are limited to 10A and they might need more (though I was told that never installations have 10A instead of 16A fuses so they'd have to be fine with the standard cable), and what kind of hoses you need depends on what you have at the place you set them up. If you don't have one, you can always buy one --- or connect your phone to your monitor that has a built-in charger or whatever. Why would you go to a store to buy a phone? When Samsung gives me a charger "for free" and I don't get one with a phone, I'd request one no matter how many chargers I already have, even if it's only make it easier to sell the phone when I don't use it anymore and because I payed for it. But I'd rather pay less for the phone and not get a charger I don't need, so why don't they give everyone the choice to buy the phone without a charger and pay less or pay more and get the phone with the charger. That would make sense. Then pay less for the phone and buy a new charger if you need one. The older is probably not any less efficient than the old one because there are limits to efficiency, and if it's broken after only 4 years it has been junk to begin with and should never have been manufactured. Yeah it's a retarded idea to use USB for charging. Get a docking station for your laptop, those are extremely nice. You don't need to plug anything in and you get more connectors on the station than the laptop has. Wow, how many hours do you spend getting ready for work? And why don't you just charge the phone at work or in your car. I said it before, these phones really need to come with docking stations like the DECT phones have and they need to be made so that leaving them on the station doesn't damage the battery ... It's a huge step backwards that they don't have that.
  23. Maybe they can, after all it's an USB connection and their crappy charger could transfer some information to the phone which it then transfers to Apple. If it's charged somehow else, it reports that to Apple just as well. But then, it would make it difficult to charge it in a car, for example, and Apple would need to provide a 12V charger as well. And then Apple would circumvent the EC regulation which could mean trouble for Apple, not to mention the privacy violation. Apple of course. The manufacturer of the charger can't repair the phone because Apple made them unrepairable. If Apple can proove it was the charger, you can turn to the manufacturer of the charger, but unless they gave you insurance (like some UPSs come with), they'll probably say they aren't liable. And Apple will say the same about their crappy charger and tell you that they can't proove which charger has damaged the phone. They'll also say the damage is not covered under warranty because it wasn't a manufacturing defect but damage caused by a charger, same as they will say it's not a defect when you drop your phone and the screen breakes (I say it would be a defect because a phone is a mobile device and the normal usage involves sometimes dropping it, so it must be build to withstand that and if they don't do that it's a big design/manufacturing issue.). It will simply say in the terms and conditions of both manufacturers that they are in no way liable for damages that their products may cause. Someone could test it ... By the time the test is done, there will be new phones on the market and the outcome of the test is no longer relevant because everyone buys a new one.
