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.

2026-01-03 03:05:35 +0100 <monochrom> It means that if I sort a list of just a few 64-bit numbers I'm already waiting 2 days.
2026-01-03 03:04:55 +0100 <monochrom> That's 2 days.
