You can make it more efficient for a specific range by using different components and settings but in general the bigger the temperature difference the less efficient.

Electricity is inexpensive in Scandinavia compared to natural gas. So even at COP 2 it's probably still worth it overall and a modern air source heat pumps can get better than that at most temperatures even down to -20°C/ -4°F.

Most air source heat pumps have a COP of 1.5-2 even when it gets extremely cold, like -20°C (-4°F). www.researchgate.net/publication/...

Even then air source HP will have the COP of ~2.3 or better. www.researchgate.net/publication/...

It turns out we owe Google 0.03 CZK ($0.0014 USD) but the minimum charge is 300 CZK.
Btw. we had $300 Free Trial credits which we almost didn't use at all because there was so much other stuff going on. It seems like perhaps Google will waive the amount because of these circumstances.

Well, depends heavily if you have or don't have the money. If you fund your venture out of your own pocket you better have a very good reason for spending a sum of money PER YEAR for which you can establish an entire elementary and high school in Europe including building the campus.

V rodině se osvědčil: Yum Asia Bamboo Rice Cooker with Induction Heating (IH) and Ceramic Bowl, jinak klasicky japonský Tiger je taky dobrá značka. Člověk myslí, že na tom není co zkazit, ale dobrý rýžovar rovnoměrněji hřeje a nestane se, že by třeba bublal/ prskal škrobovou vodu.

Tak bychom se měli postarat, aby tu jasnou většinu neměl. 🤷♂️ Vlastně je to velmi jednoduché.

Na obranu můžeme dát kolik chceme, ale nemusí to být k ničemu, pokud bude efektivita utrácení nízká. (To platí i pro školství, zemědělství, medicínu...) Hlavně 2 nebo 5 % HDP je v ekonomicky silné zemi dost jiná absolutní částka než zemi slabé.
Taky by bylo fajn nepřítele nefinancovat přes fosil.

It's pretty first class on Proxmox (whatever you may think of the system).
I would be glad if it was first class on Debian too, with compiled modules as an official package for instance and support in the installer. Shouldn't be that hard to make everyone happy.

I considered offering a service where you could basically rent IPs or IP:port combinations + forwarding in a POP near you for exactly such use cases. It could also help companies setup S2S VPNs without public IPs and much extra latency.
