We are still actively maintaining support for the Motorola 68000 CPU in the kernel which is even older.

Stable has a different context when talking about distributions. Arch does not have releases, it’s unstable by definition.

Electric vehicles cause much more CO2 emissions during production as compared to cars with internal combustion engines due to complicated manufacturing process of the battery. If you’re comparing CO2 emissions, you have to consider the full

No, it demonstrates the effect of government subsidies for electric cars in Germany. Electric car owners don’t pay car taxes for the next 10 years in Germany. And many cars are even eligible for a $10.000 discount. Of course, people buy new

Not directly but adding support for the 68080 target would definitely be possible.

Well, the previous comment also suggested to exclude RISC-V, S390x and so on which are certainly not hobbyist targets.

Yes, but GCC cannot be used as a backend for other languages like Rust. My primary goal is to get Rust support for m68k.

There is the Vampire 68080 which features new instructions. See: http://apollo-core.com/index.htm?page=products

I know about GCC. In fact, I'm the one who created the Bountysource campaign to convert the m68k backend in GCC to MODE_CC.

No one has ever built electricity storage in the required capacity. You are seriously underestimated the required capacity to just store electricity for one day in an industrial country. There is a reason why Germany is massively build new

There are no large scale storage batteries. The only large storage systems are hydro storage and even those don’t have enough capacity to store energy for more than a few hours. In Germany, all hydro storage plants combined can supply Germa

Don’t blame nuclear for corrupt and incapable politicians in the US. Nuclear plants are highly economic, at least outside the US. Every plant in Germany so far has already financed itself.

A single nuclear reactor produces electricity worth 1 million dollars per day. Nuclear power plants are money printing machines, not money pits.

Germany has 50% renewables in its electricity mix, France has 70% nuclear. France produces 50 grams of CO2 for every kWh, Germany 400 grams. If Germany hadn’t shutdown 11 nuclear power plants since 2011, emissions in the electricity sector

Because renewables don’t help reduce emissions as much as nuclear does. Renewables need fossile backup plants. Go on electricitymap.org and see how Germany has among the highest emissions in the electricity sector in Europe despite 50% rene
