: Er, sorry, I see that what I wrote was ambiguous. I wasn't complaining about the pregeneration of the 960 entries, but about the generation of 40320 permutations, only to throw most of them away. Indeed, pregenerating the 960 entries makes perfect sense, especially if you can do it at compile time, and amortize it over many runs. I've clarified my comment, and added a faster way to pregen the 960 entries via construction. Thanks for pointing out the ambiguity in what I wrote. --[[User:TimToady|TimToady]] ([[User talk:TimToady|talk]]) 18:47, 14 May 2014 (UTC)
:: Fair enough. (Though perhaps this could also be taken as an indication that generating permutations is not implemented efficiently enough? I honestly don't know. I think I was mostly wondering because the permutation approach seemed to me to be efficient enough for this problem (60 milliseconds on my overloaded laptop, though granted I wasn't using perl in this particular case), and I did not know what the issue was. And you have clarified that.) --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 20:18, 14 May 2014 (UTC)
:I make the opposite view about computers. Every winter I find myself marvelling at the reduction in the amount of cars seen with their hood up left broken down by the side of the road. I put that down to modern engine management systems.
:I also see our double decker busses just going about their business. When I was a lad, they would cough and wheeze belching smoke as they laboured slowly up hills. Now their engines have engine management systems that get more from the fuel and help diagnose problems before they lead to breakdowns.
:As you can see I think of computers as having a net positive effect. (Guided bombs and drones notwithstanding). --[[User:Paddy3118|Paddy3118]] ([[User talk:Paddy3118|talk]]) 19:45, 14 May 2014 (UTC)
:: Perhaps, indeed. (I'm not quite sure that my amish relatives would really appreciate that line of thinking, but I can certainly see its validity.) Still, from a personal contribution point of view, I feel I should be capable of doing a lot more than what I have (if only I could better identify a reasonable set of priorities and motivations for myself which fit the fragmented aspects of society which I happen to admire). --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 20:18, 14 May 2014 (UTC)
