They are currently developing the methalox Raptor [1] engine that is planned to have 2300kN sealevel thrust. That would be more than six times powerful than the Merlin 1D+s in current Falcon 9. That would be solidly in the heavy lift rocket

The same as any other house on the grid. How much power you typically use and when has almost no impact on how much grid connection costs. All that matters is the peak they must be able to deliver. That is why billing transfer together with

The moment you start mass-producing self-driving cars, people will start dying in accidents that were caused by them. Even if they are vastly safer than human drivers^+ , the sheer amount of cars on the highway and the varied situations the

Fusion reactors can use different fuels based on how good they are at containing plasma. Right now, almost all research is directed towards the easiest possible fuel that requires least powerful containment, that is, Tritium (H3) and Deuter

The last comment is very ignorant of CPU design. Clearing the highest bits of a register is not a stupid thing to do, it's what you have to do if you don't want to have false dependencies on the previous contents of the register.

But stack accesses are generally perfectly predicted, meaning that your loads from stack get executed and the data loaded into those extra registers long before your code needs to use those values.

Because you cannot make the choice to store something in internal store, it's automatically managed by the OS. The backing store for everything is the cloud.

There are a lot of new kind of more complicated instructions, but they very much follow the basic RISC principles. That is, instructions that do any kind of math take in a few register operands, output into a register, and do so quickly and

Statically memory managed already has a meaning. It means that there is no malloc during runtime, all memory addresses are decided (usually manually) beforehand and written into the executable.

We can synthetize all petroleum products from carbon feedstocks, so long as we can pay the energy cost. This is generally true of almost everything these days -- all resources that the modern economy depends on are substitutable or syntheti

It's both less and more complicated than it seems. The borrowing system is quite complicated and it will take time before you can internalize it so that you can trust your code to compile on the first try. However, Rust is the good kin

No. Europa and all the moons closer to Jupiter than it do in fact occasionally travel backwards in relation to their orbit around the Sun. This is also true of Dione and all the moons of Saturn lower than it, all the inner moons of Uranus,
