I feel exhausted. Finally, it’s time to take some break.

Running can distract my focus from all the other pressure for a short time. I now sense that why successful people run regularly: it is a way to sort of harm themselves (like wrist cut) to get distracted from stress.

    • one instruction requires 1~14 clock cycles :eyes:
    • Recent CPU has around 3 GHz frequency -> 3 * 10 ^ 9 clock cycles per second -> 3 clock cycles per 1 ns. Let’s say a program’s instructions cost 3 clock cycles on average -> 1 instruction per 1 nano second (with fast programming such as C++). However, Things are more complicated due to pipeline or concurrent instruction execution.
