The worst connector IMO is the HDMI connector. I run the mediatec at an university and the amount of well-shielded cable I have to throw into the bin each semester because yet snother perdon levered off that plug is mindboggling.
On top of that, HDMI tries to be to much and do too much
Murder is one thing, some superior telling you you cannot accept random PDFs sent to you via email for whatever reason and you following that policy is another.
Imagine you run a cash only cafe and one of your baristas starts accepting payment via paypal as a convenience to your customers. Your customers would totally dig it and see it as the morally right thing to do. You however might see some justified problems with it.
If a government office cannot accept pdfs due to policy, the policy is at fault, not the person forced to carry it out. We do not want to live in a world where office clerks make there own rules and ignore policy, based on their subjective morality, with the exception of rejecting or subverting obviously morally wrong extreme policies. Not accepting PDFs is not extreme, it is just bullshit.
I know for a fact that in my institution (a university) certain things can't be done by sending a pdf because the guidence our adminstration is accountable to (city, state, national) mandates them to have it in paper. All clerks I have talked to find that silly, but they can't change it and since they have to proof things to these superior offices one cannot expect them to forge these document for you as a service.
There are stupid, lazy clerks who take any deviance from "the process" as an excuse to refuse work, but often it is the internal rules that are at fault and not the individual.
If I create software I can do whatever the heck I want and that includes displaying a billion banners. And you got the right to not use my software.
If you trust the makers of LibreOffice enough to run their software on your machine, you might also consider trusting them on this decision. Unless of course you know better than them about what it needs to keep the software alive, in which case you might wanna give them a hint (e.g. by detailing how you would imagine it would work instead in terms of finances).

It means that the electricity you would have to pay if you did the computations yourself would be more expensive than paying them to do it. Part of thst has to do with the fact that China has cheap electricity, also due to their massive push into renewables. Part of that is just economies of scale. A big server farm can run more efficiently than your PC on average.
Normslly you'd expext that more (and cheaper) supply would drive down prices. Classic market logic.
How do do you explain that this market logic ceases to exist for renewables only? A whopping ~2TW or ~35% of generated power in China is renewable and since renewable energy is roughly 1.5 to 4 times cheaper than e.g. coal per kW/h produced that ought to have some impact.
If it has not I'd be curious in your explaination of the mechanism involved.
I wasn't surprised the least. But I am also a hardware guy. Going into production with such new technologies means first making aure it is even feasible for mass production and long term use. There are ways to speed up these tests, but if you need a battery to last 10+ years, you will only be able to speed it up by so much — especially if it is new experimental tech.
If it is, there are probably multiple intermediate small scale experiments and then the tooling and production line technology might still need to be developed as well. Someone in a lab making a theoretical discovery is not the same as something making sense commercially in the slightest.
I program for 20 years now and I think that what many people do wrong about these estimates is that they give them too early. The truth is that for many project the only truthful answer you could give someone on the question hoe long it takes is: "That depends on many things some of which I don't know, some of which we both don't know and some of which potentially nobody knows." After that you should say: "In my experience it takes betwern x and y weeks, with a lot also depending on how responsive your side is."
Time estimates are always hard, not only in programming. And outside of programming one of the main insecurities is customers changing the plan or wanting adjustments. This is the side you can't really control, so it is best to get a feeling for the customer, their communication patterns and their expectations early on and factor it in. The other insecurity is tough problems you encounter during the programming phase. How well you can deal with those depends a lot on how experienced your programmers are and how much they were involved in the inital process.
The truth is that the latter insecurities make up a main part of the whole thing and it has to be okay to tell a customer you can't give them an estimate before you know some more details.
