News on China's scientific and technological development.

We don't know what they have running internally. But if they are working with internal version it means user are not using those internal tools.
But i do think China should make something like a llvm or a gcc of their own so they can move faster and are not dependent on western approvers of pull requests. It would be awesome if Huawei could just start/finance such a national project kind of like what Apple did with Clang and LLVM if im not mistaken.

It's a low vacuum not a particle accelerator vacuum.
Partial vacuum doesn't have anywhere near the risk and dangers and one doesn't necessarily need to transport humans in any form of evacuated tube maglev transportation. Commercial goods, livestock, military equipment etc. Anything that fits. Far faster than even flying if your set up and maintenance logistics beat preparation time required for air transport.
Loading pallets onto trucks and driving them to airports (usually FAR away from city centres in China due to typical topography of landscape) vs ETM set up similar to HSR but with factory production lines instead of city metro lines. China already has the world's most interconnected supply chains. Something like ETM even if applied sparingly would absolutely take time and profit margins to another level.
They reached 623 km/h on a 2 km track.
Assuming constant acceleration until the halfway point followed by constant deceleration (and my quick calculations are correct), then it would have been accelerating (and decelerating) at more than 1.5g.
I bet some people would pay to just experience that acceleration.

China developed a high efficiency foldable solar panel.

Is that a mistake in the report? 26.81% is the efficiency, not the power-to-weight ratio, although the 57-μm thickness offers the highest power-to-weight ratio.
