Although atheists are generally liberal or libertarian. 01:21:00 But most importantly, "from time to time", as opposed to "often". 01:21:01 ah, but aren't libertarians some form of conservatism? :o 01:21:13 well, although I once saw a Darwin fish in Texas (awesome), but I meant it as... 01:21:45 that in a conservative place, such blatant non-christian stuff would be terrorized and whatnot 01:22:19 well, madbr, it's more like two seperate dimensions 01:22:23 yeah 01:22:29 economic and individual freedom 01:22:30 economic freedom, and social freedom 01:22:32 haha 01:23:07 (It's really three dimensions, though individual and social are closely tied.) 01:23:11 Liberalism has low economic but high individual/social 01:23:28 Conservatism has high economic but low individual/social 01:23:42 Libertarianism has high both 01:23:50 Statism 01:23:56 and authoritarianism has low both 01:24:01 ouchies 01:24:21 of course, me ol' gover' teacher gave us another interpro 01:24:26 When you split individual and social you get 9 different ideas 01:24:39 three facets: order, freedom, and equality 01:24:59 you can only choose two, at the expense of the third one 01:25:10 Conservatives generally pick order and freedom, at the expense of equality 01:25:28 liberals generally pick freedom and equality, at the expense of order 01:25:57 And if you pick order and equality at the expense of freedom? 01:26:05 and authoritarians generally pick order and equality over freedom 01:26:13 ha 01:26:15 They don't care about equality... 01:26:41 Communism did, before it went total-postal 01:26:54 Yeah, but they aren't authoritarian. 01:27:01 Also, a more inclusive way to define it based on those facets: 01:27:12 :O 01:27:24 (also, what were those 9 ideas you mentioned?) 01:27:41 (I don't have names for them. They're just combinations of high/low.) 01:27:49 ah, okay 01:27:59 Each starts at 0, which is average. 01:28:07 You have 1 point. 01:28:07 the facets? 01:28:10 Yeah. 01:28:12 okay 01:28:25 You can use that point to increase any of them by 1. 01:28:35 You can decrease any of them by 1 to gain another point. 01:29:20 cool, cool 01:29:29 although, there would have to be limits 01:29:36 Thus centrism just doesn't spend the point in the first place 01:29:41 defined by nature, and what not 01:29:51 wouldn't centrism spend it on order? 01:30:02 Nah, that would be... um... order-ism. 01:30:26 hey! let's use this stuff in a nomic! 01:30:49 Maybe. We'd need a good initial ruleset incorporating them. 01:31:05 yay! 01:31:51 of course, as I was telling yuri, a system requires a goal to be worthwhile, and that most countries (and nomics, and other human organos) don't have any goals above "survive" 01:32:01 Name idea: Nationomic 01:32:32 so I'm saying that in the future, if I'm involved in a nomic (or anything else), I shall always make an early step to be the defining of a goal 01:32:44 so, what is the goal of our suggested nomic? 01:32:50 Hmmm. 01:32:57 Well, it could be unwinnable. 01:33:22 Or we could have some sort of United Nations-like entity 01:33:32 and although there is no official "winning" 01:33:58 you can gain great power by becoming leader of the UN 01:34:00 also 01:34:05 we should talk about this in ##nomic 01:34:09 indeed 01:34:13 as it has drifted quite far from the topic of esolangs. 01:34:16 what network is that? 01:34:34 (remember, unfamiliar computer here) 01:34:54 Same one as you're on. 01:34:57 okay 01:34:58 hey! 01:35:03 ? 01:35:05 yuri wants to talk about it also 01:35:11 sure we can't do it in google wave? 01:35:11 Yup. 01:35:17 Sure, why not? 01:37:27 -!- Sgeo has joined. 01:37:33 hmm 01:37:48 what would be a good cpu design for some amateur project? 01:39:14 the game of life 01:39:16 ?? 01:39:19 what do you mean? 01:39:43 MISC 01:39:54 http://esolangs.org/wiki/MISC 01:45:36 that doesn't look particularly programmable 01:45:55 it could be a more standard risc although those are boring 01:49:11 -!- Oranjer has quit ("Java user signed off"). 01:52:44 -!- Oranjer has joined. 01:55:47 If I wanted to program MISC, I would make a MIPS->MISC compiler. 02:20:59 -!- Oranjer has quit ("Java user signed off"). 03:45:12 * Sgeo got yellwed at for saying wtf 03:45:20 When I meant to type wtg 03:45:24 But this was repeated 03:46:55 * Sgeo is addicted to AWBingo 03:51:50 WTG? 04:01:14 What The GOD?! 04:01:35 ...ah. 04:01:45 That makes perfect sense. 04:04:52 Way to go 04:05:15 I'm in a bingo place 04:08:02 Does it please you to believe you are in a bingo place? 04:08:52 lol 04:09:07 agh 04:09:18 I accidentally mixed code for my IRC bot and my ELIZA clone 04:18:02 ME: The world is explode. ELIZA: What does that suggest to you? 04:19:15 ME: I WILL KILL YOU ELIZA! ELIZA: Perhaps in your fantasies we will kill each other. 04:22:16 * Darth_Cliche tries to make ELIZAs talk to each other 04:22:39 ELIZA: Why are you concerned over my problem? 04:22:58 OTHER ELIZA: Your problem ? 04:26:50 So two people in AW use Base64 to swear in front of people who don't approve of swearing where they're doing it 04:26:57 I'm threatening to reveal what language they're using 04:31:21 And one of them talked about f***ing one of the other people there, so 04:34:39 So? 04:36:12 It's a G rated area, and the owners of the place already ejected someone for saying wtf 04:37:51 ... 04:38:00 WTF! 04:40:53 OMG WTF LOLOLOL 04:41:08 * Darth_Cliche creates chatbot representing typical 12-year-old 04:45:55 my trombone!!! 04:45:56 http://photos-h.ak.fbcdn.net/hphotos-ak-snc3/hs112.snc3/15956_210441155020_601130020_4464643_2268885_n.jpg 04:50:46 -!- oklofok has joined. 04:51:05 okay finally felt like learning the techniques in "how to develop a super power memory" 04:51:32 after one day's training, i had a friend tell me 42 cards from the deck and i told him the missing ones 04:51:42 (1 error) 04:54:02 also i memorized the order of a deck in ~ 10 minutes, random access, although card -> index was a bit unreliable... then again i was getting pretty tired 04:54:23 i guess that's all... people should seriously read that book 04:54:35 also you people 04:56:33 -!- Bjornung has joined. 05:06:11 -!- Pthing has joined. 05:10:39 * oklofok considers memorizing the internet 05:12:51 Is oklofok a spambot? 05:13:03 Darth_Cliche: yes 05:13:17 ...so why doesn't someone kick it? 05:14:54 haha 05:15:03 ...oh, so it isn't a spambot? 05:15:15 it's a 50 year old book 05:15:51 Ahem. Oklofok, are you a human? 05:15:55 although i guess that could still be considered spam 05:16:04 dunno 05:16:15 usually i say i'm a lizard 05:16:45 I'm a mizard 05:16:48 (doesn't mean the system doesn't work for humans, i have a human brain) 05:17:27 -!- sebbu2 has joined. 05:17:30 ...I'd accuse you of being a furry, except that doesn't quite work with lizards. Maybe a scaly. 05:17:36 Hi sebbu2 05:22:25 i wish there was a book about memorizing data structures in general, loraine was more of a magician than a computer scientist 05:22:42 * Warrigal substitutes for oklofok. 05:22:47 Usually I say I'm a dog. 05:22:49 also cs may have been slightly different in '57 05:23:14 well telling by your face... 05:24:07 Have I used the nick DogFace here? 05:24:47 I'm definitely not a Martian. 05:25:16 Warrigal: either that or you've linked pictures of yourself and your damn ugly 05:25:20 *you're 05:25:26 i don't remember which tbh 05:25:58 but yes, countless times 05:26:25 I've either linked pictures of myself countless times or used the nick DogFace here countless times? 05:26:25 Come to think of it, the name 'Warrigal' sounds like a dog breed. 05:26:28 Interesting. 05:26:51 It's a species of canine indigenous to Australia. 05:26:59 Ah. 05:27:00 i had a theory about Warrigal's nicks 05:27:05 Wait. 05:27:11 You expect me to believe that? 05:27:17 but it's somewhere deep in the logs 05:27:19 You're jacrave-ing me! 05:27:22 wait 05:27:29 you're not my RL friends 05:27:31 nvm 05:27:32 something about a sex change operation 05:27:39 Ah, yes. 05:28:01 "ihope", tentatively seeking reassurance and hoping that the operation will work out. 05:28:39 And then "Warrigal", i.e. "Warri gal", obviously post-op. 05:32:24 -!- clog has joined. 05:32:24 -!- clog_ has joined. 05:32:46 what does it say in your mug 05:32:51 Warrigal is a synonym for dingo. 05:33:04 also you look *very* different than i expected 05:33:07 oklofok: "For integral x > 0, compute the number of pairs of distinct points A and B on y = x^2 where the slope of line AB is 2008." 05:33:25 Where "line AB" is AB with an overline. 05:33:35 (unless you are the jap or something dude) 05:33:56 And "^2" is a superscript 2. But anyway. 05:34:05 I wonder what you expected me to look like. 05:34:13 "(unless you are the jap or something dude)" 05:34:21 closer 05:34:26 -!- sebbu has quit (Connection timed out). 05:34:26 ...my brother thinks "dingo" is a slang term for penis. 05:34:43 everything is a slang word for penis. 05:34:48 That's true. 05:34:51 except penis, it's just a word for penis. 05:35:00 "Everything" is indeed a slang term for penis. 05:35:05 -!- immibis has joined. 05:35:17 Also, "dick" is not a slang term, it's just a regular term. 05:35:21 Hi immibis 05:35:24 i'm pretty sure this conversation has been had here 05:35:35 Wait, seriously? 05:35:39 In this very channel? 05:35:48 hi 05:36:11 Hm, everything itches. That can't be good. /me goes to a urologist. 05:36:13 yes. i say everything is a slang term for penis, someone says that same joke. or maybe it's my first deja vu i don't recognize as one. 05:36:18 we've had a lot of conversations about penises 05:36:25 hi immie 05:36:27 You're weird, you know that? 05:36:35 yes. 05:36:46 ("You" here was plural, just to clarify) 05:36:56 i was told that today at uni, well not directly 05:37:16 it was implied via antisymmetric eyebrows 05:37:43 because i have to remove these plastic flap thingies from all the bottles i empty 05:37:51 and i do it with my teeth 05:37:55 Eyebrows that were at the same height at no distance from the median plane. 05:38:19 Ț 05:38:22 :-Ț 05:38:33 Warrigal: umm wouldn't those be symmetric 05:38:58 Eyebrows that were at a different height at every distance from the median plane? No, certainly not. 05:39:31 oh lol i misparsed 05:39:50 but point taken 05:39:59 Hey, I'm wearing my medal in that picture. 05:40:22 some sorta math medal? 05:40:26 Yeah. 05:40:32 what did you win? 05:40:39 Warrigal: The number of integer pairs on y = x^2, x > 0 that form a slope of 2008 is 2007. 4014 points in total. 05:40:53 Team high scorer, perhaps. 05:40:57 you mentioned your friend was at some sorta championships, i figured you weren't because you didn't mention that 05:41:01 oh 05:41:09 He won Most Times Accidentally Deregistered From Agora. 05:41:20 MizardX: that sounds right. 05:41:48 oklofok: I wonder which friend that was. 05:42:02 Warrigal: this was about the dinosaurs 05:42:04 the conversation 05:42:21 Ah, yes. 05:42:22 (defined as some sorta connected regions on ZxZ) 05:42:35 maybe a year ago or so 05:42:41 Yeah, 2008-ominoes or something. 05:42:48 the actual problem was trivial iirc 05:42:56 Why 2008 instead of 2009? 05:43:04 Because it was last year or something. 05:43:14 Hell, we should probably be gearing up for 2010. 05:43:16 I dearly hope the problem was not trivial, as I couldn't solve it. 05:43:37 hmm. 05:43:52 well i don't remember it, usually that happens if the problem is complex to state, or trivial to solve 05:44:24 MizardX: so why 2007? 05:44:44 It was practically equivalent to this: "A dinosaur is a polyomino of at least 2008 squares. A primitive dinosaur is a dinosaur that cannot be divided into multiple dinosaurs. Find the number of primitive dinosaurs." 05:44:58 slope of line between a and b is (b^2-a^2)/(b-a), which simplifies to (b + a). Slope was 2008, so a + b = 2008. 2007 solutions for a,b > 0. 05:45:19 MizardX: oh, that's not right. 05:45:29 Aren't there only 1003 solutions? 05:45:47 oh i misunderstood the question 05:45:50 ... oh, right 05:45:51 -!- clog has quit (Connection timed out). 05:45:51 -!- clog_ has changed nick to clog. 05:45:52 1004, actually. 05:46:26 Is a = b also a solution? 05:46:31 -!- Bjornung has quit. 05:46:33 what do you mean can't be divided into multiple dinosaurs? 05:46:45 MizardX: yeah. 05:46:54 of course it is 05:47:28 oklofok: it cannot be partitioned into dinosaurs. 05:47:37 can you define that? 05:47:48 by removing points? 05:48:07 yeah i guess that is obvious 05:48:31 or just one point? 05:48:39 Hmm? 05:48:44 ohhh 05:48:56 err 05:49:03 a = b doesn't have any distance, and thus can't form a unique line. 05:49:22 MizardX: but it's a solution 05:49:26 ;() 05:49:27 *;) 05:49:30 to the equation 05:49:32 oklofok: not of (b^2-a^2)/(b-a) = 2008. 05:49:42 not that equation, no 05:49:45 :P 05:49:52 So it's a solution of some equation. :-P 05:50:06 it 05:50:16 wrong window and accidentally pressed enter :P 05:50:32 0*x = 0*it 05:50:39 it's a solution of that equation. 05:50:59 a=b is also a solution of 3x=0 05:51:04 to an equation that was mentioned! 05:51:04 no wait 05:51:06 of 0x=0 05:51:30 also to prove that there are no solutions for x=-x: (1) x = -x (2) 1x = -1x (3) 1 = -1 05:52:12 A dinosaur is a polyomino of at least an infinite number of squares. A primitive dinosaur is a dinosaur that cannot be divided into multiple dinosaurs. Find the number of primitive dinosaurs. 05:52:16 Answer: 0 05:52:25 At a random guess 05:52:30 a line of 2008 in a row is one 05:52:32 Darth_Cliche: that's false, if there are any dinosaurs. 05:52:43 ? 05:52:48 Take the dinosaur {(0,x) | x > 0}. 05:53:00 * Darth_Cliche has no idea what that represents. 05:53:11 One square and all the squares to the right of it. 05:53:21 Ah. 05:53:28 oklofok: now enumerate the rest! 05:53:34 It can be divided into multiple dinosaurs 05:53:36 that can't be partitioned into dinosaurs? 05:53:41 both identical to itself 05:53:42 oh right 05:53:46 "if there are any dinosaurs." 05:53:49 should read what you say 05:53:58 Darth_Cliche: no 05:54:06 it can't be divided into two dinosaurs that look like it 05:54:37 or any amount in fact, any partition into dinosaurs will have at most one infinite dinosaur 05:54:52 *partitioning 05:55:24 oklofok: take the dinosaur {(0,x) | x > 0} u {(1,x) | x > 0}. 05:55:46 Warrigal: not a partition of {(0,x) | x > 0} 05:55:51 i meant that one can't be 05:56:05 * Warrigal nods. 05:56:07 "Darth_Cliche: It can be divided into multiple dinosaurs" <<< response to this 05:56:29 The obvious name for {(0,x) | x > 0} is the omega dinosaur. 05:56:46 I want to see the omega plus one dinosaur. 05:56:49 A dinosaur is a polyomino which resembles a dinosaur. Find the number of dinosaurs. 05:56:53 Answer: Infinity 05:56:56 Or 0 05:57:00 or anything inbetween 05:57:15 Aleph, not infinity. 05:57:16 seeing as how "resembles a dinosaur" is completely subjective 05:57:25 There are a lot of infinite numbers-of-things. 05:57:49 I do not, and will not ever, understand the difference between aleph and infinity. 05:58:11 Darth_Cliche: infinity is defined as follows: if a set can be put into bijection with a proper subset of its, it's infinite 05:58:30 the actual infinite numbers are then sizes of different infinite sets, again defined by what can be put into bijection with what 05:58:35 There are a bunch of definitions of infinity, and they're pretty much entirely incompatible. 05:58:46 As for aleph? 05:58:49 well right that's cardinality 05:59:05 aleph is the size of N 05:59:07 Ah, so aleph is like "infinityth"? 05:59:08 the set of natural numbers 06:00:07 I hate infinity, and always will. 06:00:21 Aleph is just the answer to the question "How many natural numbers are there?" 06:00:54 Aleph_1 is the answer to the question "What's the size of the smallest set that's bigger than aleph?", aleph_2 is the answer to "What's the size of the smallest set that's bigger than aleph_1?", and so on. 06:01:29 I have to leave now 06:01:30 -!- Darth_Cliche has quit ("Leaving"). 06:01:32 aleph^2 06:01:41 aleph^2 = aleph. 06:02:09 aleph_aleph 06:02:47 aleph is not a valid thing to put in the subscript. 06:02:54 haha 06:03:12 The smallest cardinal number greater than aleph_n for all natural numbers n is aleph_omega. 06:03:51 omega > aleph ? 06:04:22 omega and aleph are different types of numbers; you can't really compare them like that. 06:04:27 Warrigal: if it anywhere had a "line" (of any shape) of 4016 squares, you could divide the thing into two polyominoes of 2008 06:04:33 omega does have a size, though, and the size of omega is aleph. 06:04:33 so that at least puts an upper bound on the size 06:04:40 oklofok: no, it doesn't. 06:04:45 it doesn't? 06:04:47 Nope. 06:04:51 err... 06:04:53 shite 06:04:57 :P 06:05:21 at least not directly 06:05:24 I don't think I was able to come up with an upper bound on the size. 06:06:27 Warrigal: what's the size of the smallest set bigger than aleph_omega? 06:06:49 err... it totally does put an upper bound in the size, start with any cell, because we have a polyamino, we can connect it to any other cell, therefore there's a line to any other cell 06:07:04 immibis: aleph_(omega+1). 06:07:17 so you can't have 8032 cells because blah 06:07:25 Warrigal: what's the size of the smallest set bigger than aleph_(omega+n) for any natural number or aleph number or aleph_omega number n? 06:07:26 oklofok: wait, what's your upper bound, then? 06:07:36 not 8032 at least :D 06:07:43 err 06:07:54 maybe like 4016^2 06:07:54 immibis: aleph_(omega*2), if I read that correctly. 06:08:10 i'm not very good at thinking while ircing 06:08:17 Warrigal: what's the size of the smallest set bigger than aleph_(omega^n) for any natural number or aleph number or aleph_omega number n? 06:08:43 immibis: wait, I interpreted your question as if you had said "for any natural number n". 06:09:27 Then again, n can't be an aleph number, so I'll continue to interpret your questions as if you had said that. 06:09:33 immibis: aleph_(omega^omega). 06:09:41 well right, if you can't bound the thing in a 2008x2008 box, then there are two cells at least 2008 away from each other 06:09:53 those cells are connected by some line 06:10:01 which will be of length at least 2008 06:10:02 err shit 06:10:07 make those 4016 06:10:26 then you can just "floodfill" them into a partition 06:10:31 having names for infinite numbers is stupid, especially considering that basically you have "the biggest natural number" and now you've got names fo rnumbers bigger than it 06:10:49 If it touches the edges of a 4016x2008 box, you can cut it into two dinosaurs. 06:10:51 no you don't have that 06:11:03 yes 06:11:08 Heck, if its height is at least 4016. 06:11:10 so there, a bound 06:11:21 immibis: well, these are called ordinal numbers. 06:11:31 I'm sure they're useful in some way. 06:11:41 immibis: kinda like graphs are stupid because now you basically have a "branching" natural number 06:11:50 natural numbers can't branch! 06:12:02 "branching"? 06:12:10 immibis: nm 06:12:17 graphs branch 06:12:20 immibis: represent a natural number as a series of connected dots. 06:12:45 if they're connected, are they still dots? 06:12:48 immibis: i'm just saying infinity is not a natural number, therefore it doesn't have to follow the axioms, kinda like graphs. 06:13:44 immibis: you know, if you had pushed enough, you would have reached the limits of my notation. 06:14:07 exactly, that's why it's stupid 06:14:13 I see. 06:14:24 you have the biggest number, and you also have that many numbers bigger than it 06:14:58 We should come up with a notation that can express every ordinal number*. 06:15:04 ... 06:15:11 *Except those outside our (countable) model of ZFC. 06:17:22 * Warrigal ponders. 06:18:22 Let [\x, E], where E is an expression in x, mean "the smallest ordinal number greater than E for all natural numbers x". 06:19:13 "expression"? 06:19:22 i'm assuming you don't mean E : N -> N 06:19:32 partly because that would make no sense 06:19:36 Right. 06:20:16 I will not define "expression", because that word is one of the Words Whose Meanings You're Supposed To Know Already of mathematics. 06:21:05 makes sense, i'll be quiet because it'd be embarrassing if you found out i don't know what it means 06:21:54 Other WWMYSTKA: "variable", "free variable", "function", "relation", "axiom", . . . 06:46:01 -!- Sgeo has quit ("Leaving"). 06:47:58 Warrigal: are you sure the problem wasn't to find the greatest possible primitive dinosaur? 06:48:33 because i vaguely recall you talking about a plus-shaped dinosaur and saying you couldn't prove it's the biggest possible 06:48:46 well, really vaguely. 06:50:14 "...the most basic being to enumerate polyominoes of a given size. No formula has been found except for special classes of polyominoes." 06:50:34 i guess it could be a simpler problem, in theory 06:51:09 just thought i'd check because it looks a bit like the problem of non self-intersecting paths 06:55:13 -!- clog has joined. 06:55:13 -!- clog_ has joined. 06:58:26 given an infinite board size, would go be turing complete? 07:09:16 http://www.answers.com/topic/exptime 07:09:52 -!- clog has quit (Read error: 110 (Connection timed out)). 07:09:52 -!- clog_ has changed nick to clog. 07:13:07 oklofok 07:14:39 -!- madbr has quit ("Radiateur"). 07:17:15 augie 07:19:26 http://www.artofproblemsolving.com/Wiki/index.php/2007_USAMO_Problems/Problem_4 07:19:35 so i think i was right 07:20:01 oh cool solutions, now i don't have to waste a day on it 05:23:36 -!- clog has joined. 05:23:36 -!- clog has joined. 05:25:47 -!- gm|lap has quit (Read error: 110 (Connection timed out)). 05:25:58 "and since it visits a corner infinitely many times, it must visit the exterior of the rectangle." <<< what if it always goes back to the interior after visiting the corner? 05:26:27 and what's a corner 05:27:01 i mean you might have it, but then you are considering something a triviality that i don't, at least compared to the other facts you mention there. 05:27:26 win 53 05:27:27 but yeah, it's something like that, of course you need to show a reason why you go off the cycle, for any cycle there might be 07:59:59 -!- clog has quit (ended). 09:08:03 -!- clog has joined. 09:08:03 (obviously there needs to be a cycle, because there needs to be a repetition of global state) 09:08:20 well now -> 09:08:36 but anyway, you did not mention the "trick" 09:08:39 -> 09:08:55 Eh, the trick. 09:11:55 Find the leftmost cell of the topmost row.

Or fundamental. 12:09:45 right. well they do a lot of non-that 12:09:58 Applied, then. 12:10:05 hmm, i suppose. 12:10:37 Applied and eval'd research! Though I guess the latter doesn't really mean anything. :/ 12:11:07 i guess it's eval'd after peer review 12:11:59 A beer-reviewed journal is a good place to publish in. 12:12:01 althoughi'm not sure that's a very intelligent play on words 12:12:04 *although i'm 12:12:24 that joke must be used a lot in student magazines 12:12:59 hmm, seems not 12:13:11 google would know 12:13:50 Results 1 - 10 of about 105 for "beer-reviewed journal".

But I have read it. 14:04:26 four lines is O(1) 14:04:26 ais523, and duh. I wasn't serious 14:04:31 that shouldn't matter 14:04:39 facsimile: yes, but O(1) is still annoying when you have to write it n times 14:04:42 ais523, I was sarcastic 14:04:54 fair enough 14:05:03 That's only O(n), if you work on a team that's easily resolved 14:06:09 facsimile: it's still worse than the alternative 14:06:28 one of the things people should learn from computer science is that O(n^3) is faster than O(1) for small enough n and large enough 1 14:06:53 ais523, can't you make a macro to do it 14:07:02 you could in theory use a preprocessor for java 14:07:09 AnMaster: that would be horrific style, and also you'd need to run a separate preprocessor 14:07:18 ais523, yes I said that just above 14:07:24 although, that kind-of makes me want to write .java.m4 files now 14:07:37 ais523, I was thinking about abusing cpp 14:07:46 meh, m4 is better if you want to abuse something, it's Turing-complete 14:08:03 fair enough 14:08:06 I could combine it with my indentation style designed to annoy everyone equally 14:08:13 and create a language designed to annoy everyone equally 14:08:21 (the m4 would annoy Java fans, the Java would annoy everyone else) 14:08:31 yay for this web mail system. I have a limit of 50 MB, of which I'm currently using -506KB 14:08:33 according to it 14:08:42 hmm 14:08:54 it's "Sun ONE Messenger Express", used for the university 14:08:54 it would be incredibly funny if it were storing the number of bytes used in a signed 32-bit integer 14:09:05 and not /quite/ outside the realm of plausible stupidity 14:09:17 ais523, adding up the column for all mails in the inbox give me plus 506 KB 14:09:20 not minus 14:09:27 ah 14:09:34 I like my explanation better 14:09:37 ais523, so just the sign is inverted somewhere 14:13:07 ais523, in a formal English letter, what would you write above your name? "Regards"? 14:13:10 or something else 14:13:22 AnMaster: there's a complicated set of rules that nobody can remember 14:13:30 apart from people who write formal letters for a living 14:14:01 IIRC it's either "Yours sincerely" or "Yours faithfully" depending on what form of address you used for the recipient up near the top 14:14:06 ais523, well, lets say I'm writing to one of the teachers at university, one who happens to not be a native Swedish speaker and prefers to receive mail in English thus. 14:14:06 but I forget the exact circumstances 14:14:23 AnMaster: is there a need for the letter to be really formal? 14:14:52 ais523, well, I guess you could go even more formal. 14:15:00 so I guess the answer is: no 14:15:26 ais523, as for address at the top, it is an email ;P 14:15:51 (I guess that wasn't what you meant) 14:16:40 AnMaster: see http://en.wikipedia.org/wiki/Valediction#English 14:16:55 "Valediction"? 14:17:20 AnMaster: it's the name for the bit at the bottom of a letter where you sign your name 14:17:37 anyway, going off to a meeting for a while 14:17:39 ah 14:17:43 ais523, cya 14:24:10 ais523, funny thing: Now when I sent an additonal mail the count went down further. It seems that I actually get -512 KB when I take (sum of sizes of mails in "Inbox") - (sum of sizes of mails in "Sent"). 14:24:35 I have no idea what would happen if I used any other folder 14:24:52 maybe it would divide or multiply by them?

I would expect some computer generated 3D thingy or such instead. 21:21:55 Well, like I said, it's a wild compo entry. 21:21:56 Those can be anything. 21:21:59 Usually some fraction is just generic parody video style stuff. 21:22:17 And others are very vaguely computer-related, and some more directly. 21:22:29 Though they've been messing around with the categories lately. 21:23:09 Youscope was a not too shabby one; it was a demo-style thing displayed on the screen of an oscilloscope connected to a computer sound card. 21:23:35 http://www.youtube.com/watch?v=s1eNjUgaB-g and so on. 21:25:27 Currently (well, in 2009) the category split was so that "Real Wild demo" entries must be "anything that can run realtime graphics", and there was a separate "short film" category for not-programmed stuff. 21:26:59 "Most soundcards (and other players) seem to have a lowpass filter at about half of the samplerate" <-- that sounds rather like Information Theory 101 21:30:04 The Nyquist-Shannon sampling theorem part is unarguably "Information Theory 101" content; but it is a non-obvious consequence (though admittedly not so unexpected) that people actually add separate low-pass filters in. 21:30:22 ah, ok 21:31:11 What would the low-pass filter block? Surely the card can't produce any frequencies above half the sample rate? 21:31:20 unless it blocks the sharp transitions 21:31:33 I'm not quite sure; for recording it obviously makes sense. 21:33:17 hm 21:36:58 It *might* (and this is pure speculation) be there to filter out any D/A converter-caused high-frequency artifacts or noise, since (like you say) only the frequencies below half the sample rate can possibly contain any meaningful information. 21:37:13 yeah 21:37:34 e.g. to turn the steppiness of the digitiser into smooth waves 21:37:51 but we *want* the steppiness for the oscilloscope 21:39:30 I've completely forgotten all the low-level signal processing delta-sigma-based DAC constructions. "A typical DAC converts the abstract numbers into a concrete sequence of impulses that are then processed by a reconstruction filter using some form of interpolation to fill in data between the impulses." It might be that the reconstruction filter is tuned to drop high frequencies there. 21:58:09 fizzie, how did they manage those shapes? I wasn't aware they could do that 21:59:06 the OS was in XY mode 21:59:19 which means you just plot points with an appropriate signal 21:59:59 heh 22:01:20 SimonRC, do those things use CRTs or what? 22:03:26 oscilloscopes use CRTs traditionally 22:05:11 -!- kar8nga has quit (Remote closed the connection). 22:14:37 Yes, they pretty much linearly map the input voltages into X/Y deflection. 22:14:45 Though modern ones are pretty digital. 22:15:45 fizzie, about x/y how would you use voltage for *both*? 22:15:58 when in XY mode 22:16:02 with two input wires? 22:16:05 Well, for both in the XY mode; like Youscope did. 22:16:06 Right. 22:16:07 SimonRC, oh right 22:16:17 one from the left channel, one from the right 22:16:18 Left and right stereo channels in this case. 22:16:21 Gaaaa I am slow. 22:16:25 heh 22:17:04 There's something so romantic about oscilloscopes. 22:17:09 All those knobs to twiddle, you know. 22:17:51 XD 22:18:18 Best part of the electronics lab course, and the DSP hardware course, was that one got to mess around with an oscilloscope. 22:20:41 Oh, and they sell those PC-based "oscilloscopes", or data-acquisition devices, nowadays; now that's as boring as anything, just a block you connect wires to, an USB cable to, and then run some messy Windows GUI app. 22:21:10 ;-( 22:21:20 custom hardware is so much more fun! 22:21:34 fizzie, windows? :( 22:21:40 it would be ok if it worked with linux 22:22:05 AnMaster: Well, it's not like I have done a thorough study; some of them might have Linux capabilities too. 22:22:12 For some reason my work email address gets a lot of spam about data acquisition devices, though. 22:22:23 do you need a DAD? 22:23:56 "WindowsÂź 7, Vista, XP or WindowsÂź 2000 operating system" for the first google-hit, USBee: http://www.usbee.com/dx.html#PC 22:24:41 Of course those can do a lot more tricks than your old 1970s CRT oscilloscope; for example, decode and visualize communications protocols. 22:25:28 ok 22:26:07 "Linux drivers for PicoScope 2000, 3000 and 5000 Series USB Oscilloscopes 22:26:07 At Pico we were one of the first test and measurement companies to provide Linux drivers. We hope that these new drivers for the PicoScope 2000, 3000 and 5000 Series of USB Oscilloscopes demonstrates our continued commitment to the Linux platform. 22:26:07 These drivers have been extensively tested on Fedora 8, Ubuntu 8.04 and openSUSE 10.3." 22:26:18 Well, it's not *completely* Windows-only. 22:26:46 Of course the drivers are binary-only blobs and possibly do not include any sort of real application in there. 22:27:10 -!- pikhq_ has changed nick to pikhq. 22:30:17 Hmm.
