first you would need to know what COP you could reasonably get, which among other things depends on the average outside temperature during heating season if you want to use an air sourced heat pump.

The COP can be in a largish spectrum depending on these factors but typical values are 3.5 for average homes in temperate climate. Higher if you live in a warmer climate and lower if you live closer to the arctic. If you want to really do the math it might be good to get help from a professional specialising in heat pumps.

Edit: this is for heating use only. A heat pump can also be used for cooling but then the climate effect is inverted.

Indeed. atetheonion might contain a bunch of idiocy, but i would not be offended by being included there just because i was sceptical of something.

Uhhh you realize there are muskets hanging on the wall, right? I think its fair to say they don’t just make swords :)

also: you can calculate the carnot cycle efficiency of a solar cell as if it was a classical heat-power-machine, even though it has no visible moving parts.

the reason why this works and yields realistic results is because the basic principles of thermodynamics stay the same no matter if you are working with steam, combustion gasses or photons and electron gas inside a semiconductor.

downvote for lack of feathers. smh.

The current fertility rate for France in 2024 is 1.847 births per woman, a 0.05% decline from 2023

Sounds about right. Western and Central Europe is aging rapidly. I doubt Paris is much of an exception to that rule.

that sounds almost exactly like the Reichsbürger in Germany. They also claim the current German state is actually just a corporation and the laws of the German empire are somehow still applicable. They also create their own passports. And of course they are deeply interconnected with Neo-nazis.

you mean turing complete?

oh i must have missed a few orders of magnitude there. 6Mt of helium is a ridiculous amount though … what is all that used for? according to WA that is about the water volume of the three gorges dam at STP

Edit: just read the report, wow, more than a quarter of all the helium is used just for “breathing mixes” which i assume means its for scuba diving.

from the wiki article on Helium:

an estimated 3000 metric tons of helium are generated per year throughout the lithosphere.

I think the main issue here is not that we are loosing helium on a planetary scale but that the easy to reach helium from gas wells is wasted. We will never run out of helium at our current rate of consumption before the sun goes nova, if we consider all sources on earth, but it will get a lot more expensive and the supply will get less steady.

its real, though not necessarily the type of window that you described. also exists in Turkish. i have a Turkish colleague who was very proud to explain the origin of that word to us in Germany :D .

datasheet for one of the drive models apparently these have a dual SAS interface, so what you are seing could be completely normal. i dont have any experience with this type of setup though.

btw you can uniquely identify partitions by using something like lsblk -o+PARTUUID,FSTYPE the partuuid should never repeat in the output even if the partition table was somehow used as a template (though "dd"ing from disk to disk will duplicate those of course)

also check out the “SERIAL” column for lsblk to uniquely identify the drives themselves.

most dishwasher detergent formulations contain corrosion inhibitors for steel, some even contain corrosion inhibitors for aluminium though those are usually in the upper price segment.

could you run something like sudo lsblk -o+MODEL and note down the model for the drives? i kind of suspect that the HBA you are using is still doing some abstraction and is not in IT mode. the duplication could come from connecting two SAS cables to the same backplane, thus creating a sort of double image of the enclosure. this is usually handled and hidden by the HBA though if it is configured correctly.

pls also check that you are in fact using the correct ports on the enclosure. if you are not building a SAN only the “A” ports are supposed to be used and the “B” ports should be unused/free.

just a bunch of individuals drives

that is literally what JBOD means so congratulations you already have one. a classical RAID would show up as a single drive.

Initiator-target (IT) mode enables creating a JBOD with zfs vdevs on it. You can have the zfs vdevs in raidz configuration (which would give you the same drive redundancy as a hardware raid, with raidz1 performing similar to RAID5)

zfs is commonly used with a JBOD configuration on a raid controller but you can also use any other kind of controller as long as the individual drives can be written to. examples for this would be NVMe drives directly attached to the PCIe bus or normal SATA controllers. This is more a performance optimization than an issue with compatibility.

In the Netherlands you can legally buy grow kits for magic mushrooms. They are fairly easy to use, mostly just weekly/daily checks to keep moisture at the right level and making sure to harvest at the right times (you usually get multiple harvests from just one kit).

Personally i think doing a shroom trip alone is too dangerous … so maybe find a group first?

I think what he was trying to point out is that you should not expect a direct visible effect of the dwindling funds on the events on the battlefield. It will be much more indirect and delayed by month, maybe years.

thank you for the clarification.
