In some channels, hackers of hate can sow misinformation about the plight of programmers elsewhere. In our communities, groups and organisations led by young, dynamic innovators promote separatism by encouraging programmers to define themselves solely in terms of their language. 2011-04-21.txt:11:35:36: <crystal-cola> So, let me end with this. This terrorism is completely indiscriminate and has been thrust upon us. It cannot be ignored or contained; we have to confront it with confidence – confront the ideology that drives it by defeating the ideas that warp so many young minds at their root, and confront the issues of identity that sustain it by standing for a much broader and generous vision of programmers in our servers. 2011-04-21.txt:11:36:26: <crystal-cola> Now, none of this will be easy. We will need stamina, patience and SICP, and it won’t happen at all if we act alone. This ideology crosses not just our continent but all continents, and we are all in this together. At stake are not just algorithms, it is our way of expressing algorithms. That is why this is a challenge we cannot avoid; it is one we must rise to and overcome. Thank you. 2011-04-21.txt:11:44:33: <crystal-cola> elliott: Une société qui s’écroule, une économie qui régresse, des appels à toujours plus de contrôles politiques pour juguler ce déclin, la situation actuelle a un goût de déjà-vu. Bien sûr on pense à la crise 1929. Mais c’est en fait à un livre - et désormais un film - qu’il est fait référence ici. Il s’agit d’Atlas Shrugged (la révolte d'Atlas) de la philosophe russo-américaine Ayn Rand, publié en 1957.

Malament and Mark Hogarth, is a relativistic spacetime that possesses the following property: there exists a worldline λ and an event p such that all events along λ are a finite interval in the past of p, but the proper time along λ is infinite 2011-04-21.txt:11:57:51: <crystal-cola> The significance of M-H spacetimes is that they allow for the implementation of certain non-Turing computable tasks (hypercomputation). The idea is for an observer at some event in p's past to set a computer (Turing machine) to work on some task and then have the Turing machine travel on λ, computing for all eternity. Since λ lies in p's past, the Turing machine can signal (a solution) to p at any stage of this never-ending task.

Since there is an easier way 2011-04-21.txt:18:22:12: <crystal-cola> one that isn't founded on more advanced mathematics 2011-04-21.txt:18:22:38: <crystal-cola> both can be made completely rigorous 2011-04-21.txt:18:22:49: <crystal-cola> the only difference is how much work it takes 2011-04-21.txt:18:23:42: <oklopol> "<crystal-cola> you can basically do trigonometry without calculus" <<< because it's no fun 2011-04-21.txt:18:25:17: <crystal-cola> oklopol: ?? 2011-04-21.txt:18:26:40: <crystal-cola> what do you mean oklopol 2011-04-21.txt:18:26:56: <crystal-cola> 19:24 < oklopol> crystal-cola: another difference is you're not doing math, eventually you might disagree with someone. 2011-04-21.txt:18:27:05: <crystal-cola> are you talking about axiom-free mathematics? 2011-04-21.txt:18:27:30: <crystal-cola> people can disagree... if at least one of them is wrong 2011-04-21.txt:18:29:01: <crystal-cola> elliott: why do you always talk about finitism? 2011-04-21.txt:18:29:18: <crystal-cola> you always talk about it 2011-04-21.txt:18:29:26: <crystal-cola> yes you do 2011-04-21.txt:18:29:46: <crystal-cola> check the logs if you don't remember 2011-04-21.txt:18:30:30: <crystal-cola> elliott: You talk about finitism all the time, I wonder why because you're obviously not actually a finitist 2011-04-21.txt:18:30:39: <crystal-cola> elliott: Basically you're trolling.

Okay 2011-04-21.txt:18:32:34: <crystal-cola> elliott: People are having a serious discussion about metamathematics. Stop telling me off for not doing anything wrong and trolling about finitism and just generally being an ass. 2011-04-21.txt:18:35:13: <crystal-cola> elliott: wrong 2011-04-21.txt:18:36:58: <crystal-cola> what 2011-04-21.txt:18:37:15: <crystal-cola> okay I'll /ignore you too 2011-04-21.txt:18:37:24: <crystal-cola> stops us arguing as a bonus 2011-04-21.txt:18:53:57: <crystal-cola> I never got introduced to anything rigorous in my math courses 2011-04-21.txt:18:54:19: <crystal-cola> which is fine, I am able to supply my own rigor 2011-04-21.txt:18:54:32: <crystal-cola> but I do think "normal" students cannot 2011-04-21.txt:18:56:00: <crystal-cola> oklopol: Nobody ever taught me what a function was 2011-04-21.txt:18:56:22: <crystal-cola> oklopol: I think you are very lucky to have been taught things properly - I am a sample of 1 but I don't think it's normal 2011-04-21.txt:19:01:56: <crystal-cola> that was weird 2011-04-21.txt:19:02:03: <crystal-cola> someone disagreed with me in #haskell and I didn't get banned 2011-04-21.txt:19:03:16: <crystal-cola> oklopol: yeah seriously I think you just go to an exceptionally good university 2011-04-21.txt:19:03:26: <crystal-cola> normally none of this stuff gets talked about 2011-04-21.txt:19:06:32: <crystal-cola> it doesn't really matter how math is taught 2011-04-21.txt:19:06:43: <crystal-cola> if you're smart you'll probably prove good theorems no matter what 2011-04-21.txt:19:13:34: <crystal-cola> category of finite sets 2011-04-21.txt:19:14:10: <crystal-cola> that definition of infinite set works without choice 2011-04-21.txt:19:15:56: <crystal-cola> anyway axiom-free mathematics is to just brush aside since axiomatization is "solved".
