Who does the tickling doesn’t matter – whether ARM or RISC-V CPU, or even a state machine – the peripherals respond just the same. Thus, one can effectively give the same “body” two different “personalities” by switching out their “brains” – by switching out their CPU cores, you can have the same physical piece of silicon run vastly different code bases.

M5 Pro and M5 Max both use the same 18-core CPU die, but Pro uses a 20-core GPU die, and Max gets a 40-core GPU die. (Because the memory controller is also part of the GPU die, the Max chip still offers more memory bandwidth and supports higher memory configurations than the Pro one does.)

Country’s airspace is closed for duration of war，这一点在新收录的资料中也有详细论述
There is a plan to prevent such a strike—the Space Surveillance Network, a bevy of sensors that the military uses to track space debris. NASA monitors what’s unofficially known as the “pizza box,” a sort of no-fly zone around the ISS. When pieces of debris are predicted to enter the box—if there’s at least a 1 in 100,000 chance of collision—mission controllers order avoidance maneuvers, firing thrusters that move the ISS and dodge the trash. The technique has been used dozens of times since the first ISS module launched in 1998. But the system only tracks about 45,000 larger pieces, and all sensors have noise. Plus, risk thresholds can miss stuff, sometimes badly. In 2025, Chinese astronauts were briefly stranded at their station after debris hit their return vehicle.
