| 2026-01-03 03:14:11 +0100 | <monochrom> | Once again the fallacy of seeing O/Θ/Ω("n") and thinking "I only see 'n', so linear time, and if I can easily make a 1000x speedup then it's fast", forgetting that really n = 2^k where k is the number of input bits, so you're looking at exponential time, at which point a 1000x speedup fails to catch up. |

| 2026-01-03 03:08:16 +0100 | <monochrom> | OTOH if the list has 1,000,000 numbers, we are spawning 1,000,000 threads. At that point the OS overhead of spawning so many threads becomes unbearable; and even if you find a way to tolerate it, the huge uncertainty that some threads start counting early, some others start count late, means that your sleep time cannot be as short as 1ms. |
