Hardened systems with hardware enforced isolation (virtualization and stuff)

You can with ADB, but yes that’s obnoxious

Another poster figured it out. Real photo of houses - mangled by AI when trying to add the car

There’s an ESP32 with MMU running Linux now

It’s because he has no real ideals and broken morals

Only the subset they like (it shouldn’t take you long to find what they said about why they made their own project, like who they wanted to exclude)

Technically yes, but that’s a pretty common design

When plan 1-8 are over, you have Plan 9 in the file cabinet

Your comment makes the error of assuming “not peak efficiency isn’t good enough” even if a ratio just above 1 pays off if other energy sources are more expensive. Such as when you need more heat than the burned waste can provide. Or when you need to maintain the temperature of the hot water tank after filling it. You just need it to pay off before you need to replace the equipment.

Literally just see the video you responded to - some of these tanks can even maintain a thermal gradient in a single water tank and doesn’t have to heat it all to max at once, and some can even provide water out at multiple temps this way. If you get that kind of machine that delta is irrelevant. And also, as the video shows, the top-up heating efficiency is actually high - when it starts at a high temperature and raises it a few more degrees.

You’re also forgetting the per-machine overhead - a home having multiple heat pumps helps in large buildings, but you do not want one for every tap, etc. You want them where you have large thermal energy flows.

If you live somewhere you can’t install it (because you don’t own the building) sure. If you do own the building (or have permission) then it works in pretty much any place you can dig deep enough

You can have both!

Also, see reverse flow heat exchangers

But that’s not a technical limit, it’s a cost saving engineering limit

Also you can pull heat out much faster when needed. If there’s heat left when you’re done you can feed it back with a heat exchanger

Enhanced Vapor Injection (EVI) is the engineering feature that separates capable cold-climate heat pumps from standard units. By injecting refrigerant vapor mid-compression, EVI compressors achieve two key benefits:

Higher discharge temperature: Enables delivery of 60–80°C water even at -20°C ambient, without staging.

You assumed 0°C? They solved it at winter temperatures most of Sweden sees.

Any COP above 1 eventually pays off, as long as it does so before the equipment is due for replacement you’re good.

Most houses have hot water tanks

It’s possible to heat things like return water or cold water directly and then use heat exchangers.

Temperature differentials also doesn’t matter much because temperature doesn’t directly behave like voltage, if your hot source is too hot you simply use less hot water (lower flow). You’d likely end up with multiple heat pumps throughout a larger home, but each one can be smaller as they cooperate.

Here in Sweden we already always distribute to homes at 70-100°C and then at 50-55°C internally (again, with heat exchangers to minimize energy loss). And that works just fine. We just don’t (yet) have many systems which feed back thermal energy.

You can easily feed back to a central hot water tank, then let the central heater rest as another heatpump returns energy to it.

We already have hot and cold water distribution. Most Swedish homes have central heating using hot water radiators, and central cooling is now starting to become a thing here. Any sink in a house has hot and cold water.

It’s absolutely possible to tie into this by making use of recirculation systems where you have constant flow of hot/cold water and every household source of heat or AC unit for cooling can tap into it (pun intended) to feed back generated heat or contribute to cooling. Then you use storage systems (thermal mass or thermoelectric generation) for the excess.

The amount of available RAM (which includes RAM actively used for caches but which will be immediately reassigned by the OS if requested by applications) matters more if you do a lot of task switching.

If properly annotated with dates, no. It’s the stochastic nature of the models which cause hallucinations, they don’t build a proper fact based worldview

You’re not allowed to use it after downloading it for free unless you use it on Apple hardware that it paid for. If you don’t have Apple hardware you only have a file you’re not allowed to use. Paying for Apple hardware pays for the license permitting you to use it.

That’s like saying that using a fixed cost subscription service is free because you’re not paying at the time that you access it.
