What if a piece of software isn't packaged, like for example the ARM GCC toolchain. In a Dockerfile I just need to curl and unpack it. How do I solve that with guix?
You can have different standards for different use cases. So you mean that iMessage and rcs are so different that Android can't use iMessage or apple couldn't use rcs? We don't need to find one standard to rule them all. But we need to stop anti-competition behavior like allowing these protocols to be exclusive.
The reason gsm, 3g, 4g, sms and so on succeeded was because everyone could implement them. I guess you had to pay license or patent fees, but they are not walled gardens. Phones from different manufacturers and/or different operators can communicate. I'm surprised that "chat"-protocols are allowed to be monopolies by the regulators. The regulators probably don't understand tech.
The roundtrip time is never consistent. Light travels with different speed in fiber depending on the temperature. This is why you calibrate every second.
Tax, if your country has capital gain tax you need to declare every single trade to real USD. When you are trading between crypto pairs you are not realizing any gain, thus you don't need to declare it. Until you eventually sell of course.
I'm also a proponent of nuclear, but modern nuclear power plants seem to take 15-20 years to construct and typically go 10s of billions of EUR over budget. So one does not simply "build a reactor".. look at Olkiluoto 3 in Finland, Flamanville 3 in France and Hinkley Point C in UK.
This is only half the story. What is actually happening is that Sweden is importing expensive electricity from the baltics and exporting it to Germany. So even though the electricity is only in "transit" through Sweden, the prices go up in southern Sweden. Obviously everything is working as designed, but it does feel a bit unfair.
To lower the prices in southern Sweden either southern Sweden or northern Germany must increase "plannable" electricity production to avoid expensive imports from the baltics.
I would never own a car. But I suppose I don't want to drive a car that is older than 3 years and I don't enjoy selling used cars. I prefer the freedom I get to just hand the car back after 3 years and don't have to think about it anymore. Also no unexpected service costs and so on.
