The problem is not that society is too complexity but extremely unequal distribution of money. Those few that have most of it usually did not earn it by providing a useful service to society and for them it becomes a random investment game without consequences which creates additional winners that also never produced something useful.

XML is already terrible. But the main problem seems to be that they created something similar but incompatible to make.

There is something fundamentally wrong with Windows or Visual Studio that it requires ugly solutions.

This is fitting for something simulating cargo, which is a huge supply chain risk itself.

That Rust gives you correctness is very misleading claim.

Memory safety is not the same a scorrectness and more advanced type is also not the same thing as correctness.

One could import it as ammonia from locations that can produce a lot of it via solar.

True, but higher demand for heating in winter is not specific to Germany. In the end, Germany will likely need to import energy anyway - just as it does today. But this means this question may not be the most relevant.

Germany has more wind in winter, so traditionally has more production of renewables in winter months.

It also has to be considered in light of the fact that Lennart builds a company for "cryptographically verifiable integrity on Linux".

Not sure what you are trying to say. Inconsistent definitions is a consequence of being able to build things separately, which is a major feature of C and C++, although in C++ it does not work well anymore. The reason to not build things piecemeal is often that LTO is more expensive. But occasionally running this will catch violations. When libraries get split up, the interface is defined via headers and there is little risk to get an inconsistency. So really do not think there is a major problem in C.

It will be a mix. There is certainly still a lot which can be done on the demand side, e.g. when to cool a cool storage house during the day, or when to run certain production lines.

No, capacity factor is a distraction. The only meaningful question is whether it is cost effective or not compared to other production methods,, and solar - taking into account the low capacity factor - is starting to look very good.

Better importing solar panels once in a while than importing fossil fuels all the time.

C++ ODR requires different definition to consist of the same tokens, and if not the the program is IFNDR. Name mangling catches some stuff, but this becomes less relevant today with more things being generated via templates from headers.

In C, it is UB when the types are not compatible, which is more robust. In practice it also easy to avoid with the same solution as in C++, i.e. there is a single header which declares the object. But even if not, tooling can check consistency across TU it is just not required by the ISO standard (which Rust does not have, so the comparison makes no sense). In practice, with GCC a LTO build detects inconsistencies.

The ODR problem is much more benign in C. Undefined behavior at translation time (~ IFNDR) still exists in C but for C2y we have removed most of it already.

Why does this need to access to all my repository just for generating a PR?

There is a lot of tooling for C though, just not in mainstream compilers.
