If you don't, you may choose to choose another choose. 00:23:43 -!- FireFly has quit (Quit: swatted to death). 00:33:07 I invented a Magic: the Gathering card: All non-legendary permanents have Cumulative Upkeep-double your life total. At the beginning of each player's first main phase, if that player's life total exceeds one million, that player loses the game. 00:34:05 (This text is on a Legendary card, which means you cannot sacrifice it to itself) 00:37:34 https://github.com/mozilla/narcissus/pull/31 <-- has everyone observed my greatest piece of code ever written? 00:37:52 What happens if you feed that thing space? 00:38:04 It gives a correct result (false) 00:38:09 Because x.x is undefined :) 00:38:11 glogbot, ow my brain 00:38:13 Hm, right. 00:38:14 (And x. is a syntax error) 00:38:15 What's with the first param though? 00:38:23 glogbot, ow my brain 00:38:24 glogbot 00:38:33 Dammit Yahweasel don't screw up my tab complete like that. 00:38:34 elliott: ... the first param is the character being checked ... 00:38:40 Oh, the param named "first" X-D 00:38:44 Derp derp 00:38:49 Some characters are allowed as the first character, others aren't. 00:38:59 first says "oh by the way this is the first character so test it in that position" 00:39:06 * elliott ponders embarrassing Gregor by posting "I think it needs more cowbell." as a comment on that pull request. 00:39:12 * pikhq is certain that tup is the best thing evar 00:39:25 pikhq: IT'S STILL AN AGENT OF THE UNIX MILITARY-INDUSTRIAL COMPLEX 00:39:29 Yes I can see how it works. 00:39:42 Although it is strange and I do not know why you want this code. 00:40:03 elliott: So's everything else. 00:40:10 pikhq, EXCEPT WINDOWS 00:40:16 (Note: lies.) 00:40:22 Phantom_Hoover: I CAN MAKE IT 00:40:33 (Windows is the most subtle and effective part of the UMIC.) 00:41:01 zzo38: JavaScript allows any character in the Unicode letter classes to be an identifier character. That's thousands of characters, and there is no simple test for which is which (conventionally people just have a giant list) 00:41:30 That is a problem of Unicode, I think. 00:41:31 zzo38: Narcissus is a JavaScript interpreter in JavaScript. 00:41:51 Yahweasel: :trying to justify any non-trivial bit of code to zzo38 as not being a problem of the perfectly good things you're using: 00:41:53 elliott: Then that program is cheating 00:41:57 zzo38: What. 00:42:06 Yahweasel: (OK, I do this too :P) 00:42:38 It's not cheating, it's metacircular :P 00:42:47 O, is that different? 00:42:53 -!- Yahweasel has changed nick to Gregor. 00:42:58 YOU FEEL METACIRCULAR PUNK 00:43:02 WELL, DO YA? 00:43:10 * pikhq is increasingly of the opinion that hand-writing a ./configure and a Tupfile is significantly better than using Autocruft. 00:43:25 It's awesome to watch pikhq slowly turning into me :D 00:43:28 Metacircular = using host interpreter features to enable the guest interpreter, short of actually polluting one with the other. 00:43:28 -!- coppro has joined. 00:43:30 JUST AS IT HAPPENED WITH PH 00:43:57 And pooppy. 00:44:08 elliott: You'll note that I have been wanting something better than Autocruft for years. 00:44:18 ♥ autotools 00:44:24 It's just that most things made it even more painful. 00:44:33 pikhq: "The change would be very subtle... It might take ten years or so..." 00:45:43 Perhaps the only "problem" with Tup is that it can't really do the equivalent of "make install" or something. Due to it only focusing on building shit. 00:46:08 Though that's easy enough to fix. ./install 00:46:24 -!- augur has quit (Remote host closed the connection). 00:46:50 I am upset that noöne has asked me why Windows is a vital part of the UMIC, but I suppose I'm just nicking it from someone else. 00:46:59 Phantom_Hoover: because it's so bad it drives people to it. 00:47:09 What is UMIC? 00:47:13 Oh, it's because it was obvious. 00:47:32 zzo38: Unix Military-Industrial Complex 00:47:42 What does that mean? 00:48:03 Snark. 00:50:05 OH BY THE WAY GUYS: Not only does JavaScript support Unicode identifiers and whitespace, it supports Unicode numbers. 00:50:31 Why does it need to support any of these things? 00:51:36 Unicode identifiers for foreign-written code, Unicode whitespace for no half-decent reason whatsoever, and Unicode numbers is the worst idea ever conceived of. 00:53:34 Well, I can understand full-width space. 00:53:54 CJK looks all sorts of weird with half-width spaces. 00:54:28 pikhq: Then they should support full-pitch punctuation as well, isn't it? 00:55:28 The Ogham space mark is the most vital piece of whitespace. 00:55:32 A better code would be one where no lookup tables are needed for this purpose since the information about letters, punctuation, direction, converting uppercase/lowercase, numbers, etc, would be encoded in bits that are part of the code-point. 00:55:44 Gregor: so who won libc.so ? 00:55:51 zzo38: Enjoy your infinite foresight. 00:55:54 This is the problem with unicode, that is requires large lookup tables. 00:56:04 variable: Still not allocated yet >_< 00:56:09 variable, some guy. 00:56:25 Ogham/og/ha/m/o/gh/am/ogha/m 00:56:29 Also, from now on prices in this channel are all to be given in libc.sos. 00:56:46 1 libc.so = ...I forget, it's around $1000. 00:56:52 $1,350 00:56:54 But we'd have to talk in nanolibc.sos for everything that anyone but Gregor can actually afford. 00:56:59 Phantom_Hoover: no kidding. You sure it is not a gal? 00:56:59 :D 00:57:07 Nah, just microlibc.sos. 00:57:13 zzo38: It'd be fairly hard to design an encoding that was both compact *and* encoded that useful information... 00:57:25 -!- augur has joined. 00:57:31 variable: "Guys" is fairly gender-neutral as these things go. 00:57:40 zzo38: Though it would have the neat property that useful predicates on characters would be a trivial matter of looking at a bit. 00:57:45 "Some guy with a vagina" 00:57:48 X-D 00:58:05 Gregor: The worst part is, that does not actually parse as "off". 00:58:08 "I was fucking some guy last night" "You're GAY?" "No, are you sexist?" 00:58:25 METASEXISM: You assumed the first speaker was MALE 00:58:39 OOOOOOOOOOOOOOH 00:59:16 So Minecraft costs almost precisely a millilibc.so. 00:59:39 Apparently Minecraft costs $1. 00:59:40 Who knew. 00:59:44 Though I think that "Some guy with a vagina" would plausibly get interpreted as someone trans... 01:00:03 Some vagina with a guy. 01:00:04 Gregor: wat 01:00:09 Oh :P 01:00:41 Phantom_Hoover: Lookin' for centilibc thar genius? 01:00:46 YES ALL RIGHT 01:01:00 <-- uses imperial digits 01:01:00 DON'T MOCK ME WITH YOUR ABILITY TO DIVIDE BY TEN 01:01:10 THAT REMINDS ME 01:01:34 Gregor: USE EMPIRICAL DIGITS INSTEAD 01:01:37 Apparently German eggs don't come in dozens. They come in double baker's third dozens. 01:01:43 `addquote DON'T MOCK ME WITH YOUR ABILITY TO DIVIDE BY TEN 01:01:45 Gregor: X-D 01:01:46 elliott: I know. I was semi joking 01:01:47 372) DON'T MOCK ME WITH YOUR ABILITY TO DIVIDE BY TEN 01:02:18 Gregor: ... They split an egg in 2/3rds? 01:02:49 pikhq: No, they come in boxes of a double baker's third dozen! 01:03:08 So, 2*(3/13) 01:03:14 Again: they split an egg in 2/3rds? 01:03:21 Your application of "baker's" leaves much to be desired. 01:03:28 A baker's dozen is 13. 01:03:29 Also "third" 01:03:54 A baker's dozen is 13, and half a baker's dozen is 6.5, but what's a baker's half dozen? 01:04:07 Your application of grammar makes Grammar Hitler want to kill some Grammar Jews. 01:04:24 I'm ordinary Hitler and I just want to kill some ordinary Jews. 01:04:36 It shall be the Final Grammatical Solution. 01:04:46 elliott: You would! 01:04:48 -!- copumpkin has joined. 01:05:20 Oh, Hitler! You and your wacky antics! 01:05:21 I don't know how else to put it. 01:05:28 They come in a double baker's third dozen. 01:05:42 I don't really understand egg unit conversions so I have to present it in terms of dozens. 01:05:51 Gregor: Give a number. 01:06:08 pikhq: It's double a baker's third dozen! 01:06:16 `addquote Oh, Hitler! You and your wacky antics! 01:06:18 373) Oh, Hitler! You and your wacky antics! 01:06:31 Gregor: OK, so. 01:06:36 A dozen is twelve. 01:06:36 * pikhq shall just assume they have 2/3rd eggs in Germany. 01:06:38 A half dozen is six. 01:06:42 So a baker's half dozen is seven. 01:06:48 So they come in fourteens. 01:06:51 Erm. 01:06:52 No. 01:06:55 So a baker's third dozen is... 01:06:59 A third dozen is twelve divided by three. 01:07:04 Which is four. 01:07:06 So they come in eights. 01:07:09 Gregor: Do they come in eights? 01:07:11 No. 01:07:13 Wait. 01:07:18 Gregor: A baker's third dozen would be 5. 01:07:18 Gregor: Ten. 01:07:20 They come in ten. 01:07:22 Erm, elliott. 01:07:25 Right. 01:07:28 So they come in twice that, i.e. ten. 01:07:29 I think that's what he called it, yeah. 01:07:45 Why the pfargtle would they come in 10? 01:07:49 I mean I know what ten pencils is or something, but not what ten ... eggs is. I just don't get egg unit conversion. 01:08:11 ... Why do they come 01:08:17 in dozens here, anyways? 01:08:33 pikhq, 12 is a much nicer number than 10. 01:08:33 Gregor: "Egg" is the unit. 01:09:03 Phantom_Hoover: It'd be nicer still if we used base 12. 01:09:10 Gregor is trolling pikhq so successfully :P 01:09:10 pikhq: Because that's how many eggs a non-union hen lays. The German Hen Union went on strike to reduce their egg production. 01:09:12 Yes, it would. 01:09:29 Alas, we don't have six fingers on each hand. 01:09:58 Unless, of course, you killed my father. 01:10:03 In which case, prepare to die. 01:10:05 Base eleven could work, if we kept our hands in our pockets. IT'S FUNNY BECAUSE OF PENIS 01:10:33 "Nine, ten, ... aww, damn, time to open the porn bookmarks." 01:12:04 Phantom_Hoover: BTW, there are cultures with base 12 numbering. 01:12:15 Just not many. 01:12:58 pikhq, including whatever Euro-Arabic-whatever milieu is generally called Western culture. 01:13:27 I mean, there's a reason eleven and twelve are special cases, and dozen exists as a word. 01:13:47 And time is base twelve too. 01:13:54 Eleven and twelve are not remnants of a base 12 numeral system. 01:13:56 Or base twenty-four with decimals or similarly-awkward constructions. 01:14:11 Phantom_Hoover: Remember that imperial units are base twelve. 01:14:24 Apart from actual honest-to-god pure numbers, we used to be pretty damn base-twelve. 01:14:25 And only in Germanic languages... 01:14:44 pikhq: Then why are the word "eleven" and "twelve", then? 01:14:50 elliott: We used base-12 units with base-10 numbers. 01:15:12 pikhq: Sure, but we tended to always use the closest unit, unlike metric, where we tend to stick to three decimal places. 01:15:14 You know what I mean. 01:15:17 zzo38: Cognate with something like "one ten" and "two ten", and evolved into special cases. 01:15:41 And "dozen" is cognate with "duodecim", coming by way of French... 01:15:49 Phantom_Hoover: Remember that imperial units are base twelve. 01:15:54 Hahahaha no. 01:15:58 Sorry, s/duodecim/DVODECIM/ 01:16:03 OK they're base twelve except on Sundays. 01:16:07 And full moons. 01:16:12 And, yeah, only certain of the imperial units are base twelve. 01:16:16 Some of them are base-WTF. 01:16:25 yards 01:16:26 gallons 01:16:27 Most of them, really. 01:16:31 base 3 01:17:22 Uh, the units of volume are powers of *two*... 01:18:03 Modulo confusing instances, of course. 01:18:13 (3 Tbsp to the jigger...) 01:18:43 SI prefixes: THE FORCE OF BORING IN THE WORLD??? 01:19:29 Heck, the whole imperial system would actually make some *sense* if it were base 12. :P 01:26:22 Assume you are playing Magic: the Gathering with many players, all for themself (no teams). The card is "Whenever a player loses the game, choose one -- You gain 20 life; or target player loses 20 life."

There are a few differences. Do you ever play Go? 04:37:14 oklopol: you literally just need (N -> N) in any total FP language :P 04:37:18 go seems okay 04:37:34 but i haven't played enough go to know for sure 04:37:41 it might suck ass too once you get the hang of it 04:38:07 elliott: sure 04:39:02 oklopol: i wonder if the analogue of the game with all computable functions is somehow non-trivial to AI 04:39:03 well 04:39:08 i guess it's hard to define "picking a computable function" 04:39:11 but maybe the rules should be changed in some way, one piece per turn and four in a row seems kinda meh when you have soooo many of them dimensions 04:39:20 infinity in a ro 04:39:20 w 04:39:24 :D 04:39:28 i love it! 04:39:35 and you can place infinity per turn, but somehow it's restricted so you can't put them all in a row 04:39:41 basically everything is infinite. 04:39:41 also you always put down an infinite amount of pieces 04:39:44 yeah 04:39:45 yes 04:39:59 oklopol: also, maybe instead of integer coordinates, they should be reals themselves 04:40:05 not for any reason, just, you know 04:40:06 more infinite 04:40:06 :DSA 04:40:42 A problem with the game of Go is that it has no well-defined end condition. 04:40:56 maybe games are also played infinitely long 04:40:56 that's more an awesome thing than a problem :) 04:41:00 oklopol: yeah 04:41:06 oklopol: and all games started at the beginning of time 04:41:11 you get a random one from all possible games, and start from there 04:41:21 and it's always had infinite moves done 04:41:23 zzo38: i don't think that's very relevant 04:41:36 well it's certainly not relevant in the current discussion, but i mean even for go 04:43:42 elliott: i meant more like, for each ordinal, you define a partially filled board by taking the union of all the last ones and then applying the player functions in succession, then play until the first uncountable ordinal 04:43:47 A variant of Go has well-defined end condition, capturing and placing stones is the same as Go, but it ends when one player has five in a row.

Anyone want to have a look at it? 04:44:54 imagine inf-d four in a row 04:44:58 things fall infinitely far down 04:45:00 :D 04:45:06 dbc2: oh dear, that sounds scary 04:45:17 http://pastebin.com/B5tpPxD8 04:45:37 It seemed like the best way to limit the time a computer thinks for, in a two-player game. 04:45:58 * oklopol now wants to do math on inf-anf-oh 04:46:19 dbc2: linux, i assume 04:46:22 When the alarm goes off, it should jump out of, probably, a deeply nested recursive call, and use the best answer it found yet. 04:46:25 Yeah, linux. 04:46:27 i dunno how irix or hp-ux would react :-) 04:46:45 It works fine the first time, but the second time, the alarm doesn't go off. 04:47:06 dbc2: Perhaps the signal handler for SIGALRM is defined to be cleared when it goes off or something else similarly stupid? 04:47:17 dbc2: The signal handler has to return for it to work. 04:47:31 oh, right 04:47:36 you're not allowed to do that in signal handlers full stop 04:47:39 Make instead, use timing inside of the code making the decision. 04:47:57 dbc2: if the thinking is divided into neat "steps" in an infinite loop 04:48:00 A signal handler cannot return if it uses longjmp 04:48:02 you could condition it on a volatile global boolean 04:48:07 and the signal handler can just flip it 04:48:27 elliott: Yes, that way will work better I guess 04:50:56 http://www.gnu.org/s/libc/manual/html_node/Longjmp-in-Handler.html 04:51:12 hmm 04:51:18 i'm fairly sure that's gnu-specific at the very least 04:51:42 how odd 04:51:58 * elliott tries to figure out which one of pastebin.com's buttons downloads. sigh. 04:52:06 well, ok, it's download 04:52:11 but "raw" isn't actually raw... 04:52:45 It is why, I prefer sprunge instead (I learned about sprunge from this channel, actually) 04:52:59 hmm 04:53:07 dbc2: Are you sure it is OK to setjmp to the same jmp_buf twice? 04:53:12 I guess so, since the gnu code does 04:54:20 The problem is that the signal handler cannot return if it uses longjmp. It is required for a signal handler to return. 04:54:22 dbc2: hmm... stepping through it in gdb but the longjmp doesn't make me hopeful 04:54:32 zzo38: incorrect, at least for glibc: http://www.gnu.org/s/libc/manual/html_node/Longjmp-in-Handler.html 04:55:15 I know there is the Linux man page tells you which commands are allowed in a signal handler, look at that for information. 04:55:49 zzo38: incorrect, at least for glibc: http://www.gnu.org/s/libc/manual/html_node/Longjmp-in-Handler.html 04:55:52 longjmp is allowed. 04:57:33 dbc2: interestingly, if i use alarm(9) 04:57:39 OK, I looked at that. 04:57:43 dbc2: then it interrupts much before 9 seconds the first turn 04:58:09 wait 04:58:10 never mind 05:00:33 dbc2: have you tried it with non-alarm signals e.g. sigint? 05:00:39 The problem is that when the signal handler is called, the signal is blocked. 05:00:54 It's automatically unblocked upon exit, but you don't exit. 05:01:03 Ahhhh 05:01:11 I wonder why http://www.gnu.org/s/libc/manual/html_node/Longjmp-in-Handler.html fails to mention this 05:02:45 fizzie: See? I told you. 05:02:48 At least that's my guess, anyway; man 2 signal says it's a bit platform-dependent whether it does the blocking or something else. 05:03:03 zzo38: You didn't tell fizzie, and besides, you were mostly wrong. 05:03:15 It is OK to use longjmp in the handler if you're aware of that. 05:03:56 You can use sigaction with the SA_NODEFER flag to explicitly have it not block the signal while in the handler. 05:04:09 There are the commands sigsetjmp and siglongjmp which will deal with blocked signals. 05:04:59 There is also that, right; those can restore the signal masks 05:06:02 Awesome. Thank you. (Is there a way to directly unblock a signal?) 05:07:52 (Just curious. Sigsetjump and siglongjmp fixed it.) 05:11:24 sigprocmask(SIG_UNBLOCK, ...); needs the signal specified via an awkward sigset_t, though. 05:11:38 -!- copumpkin has quit (Quit: Computer has gone to sleep.). 05:12:20 Does anyone know of a high-performance boids program? 05:12:36 http://www.reddit.com/r/coding/comments/gumj1/tinyflock_a_simple_highperformance_threaded_and/ is making me drool over the idea of a fancy-spatial-data-structured GPGPU-accelerated boids program. 05:12:43 OK not actually drooling. 05:14:19 I'm sure someone's done some sort of boids CUDA example somewhere. 05:14:25 dbc2: BTW, you'll want to set a global to condition on whether to longjmp; after all, you could finish the computation in half a second and still get a longjmp when the alarm goes. 05:14:32 fizzie: But will IT use a kd-tree???? HUH? 05:14:36 I have updated the Boids code to get 10000 boids on screen at once at 30 frames ...

Such as, specific to chess, shogi, tsumeshogi, etc 06:58:18 Alpha-beta pruning does work better if you order the moves properly; and if you're doing something like iterative deepening, you can use the previous rounds' results to order them. 06:58:56 zzo38: no idea, but to give an example of what alpha-beta pruning means in this, say one move has been deemed okay, and after another possible move, your opponent can eat your queen, giving him a very nice estimated utility; it then makes no sense to look at his other possible moves, because no matter how much better they are than eating your queen, you will not let him eat your queen anyway! 06:59:06 I seem to recall that alpha-beta pruning with optimal move ordering would turn b^d nodes-to-search into b^(d/2). 06:59:16 "means in this" 06:59:18 what 06:59:23 zzo38: i have wikipedia's Sprouts game in my watchlist, one of the links there is to someone who uses quite interesting theory based on nimbers to get shortcuts from symmetry 06:59:45 they've used it to calculate winning player for various starting positions 07:00:17 oklopol: But sometimes it might be the better move that requires queen sacrifice 07:00:46 ... 07:01:39 the algo has already checked that after eating your queen, your opponent goes on to eating your king and your physical body 07:01:53 oerjan: Yes, it is like what I mean, like symmetry. In shogi you can have the board horizontal mirror is equivalent. 07:01:57 oklopol: O, it does, OK. 07:02:03 point is after that, alpha-beta pruning cuts off the search for a strategy for the opponent that lets it eat the whole fucking world 07:02:07 zzo38: also i've never read it myself but the book in http://en.wikipedia.org/wiki/Winning_Ways_for_your_Mathematical_Plays probably contains many such tricks 07:02:18 -!- lament has quit (Ping timeout: 240 seconds). 07:02:50 there was some fun book that contained x-completeness proof for tons of different games 07:02:55 In a chess game without pawns, you can rotate/mirror any direction to make equivalence. 07:02:57 but i couldn't access it anywhere 07:03:04 except a partial google books version 07:03:22 But shogi is different and can never make this. In shogi only horizontal mirror symmetry counts. 07:03:45 symmetry doesn't give you much in search unless you use it in some very clever way 07:04:33 -!- azaq231 has quit (Quit: Leaving.). 07:05:47 oklopol: Yes, I can understand that it is. 07:07:55 oerjan: have you read mathematical playes 07:07:56 zzo38: sadly i don't think chess and the like have the right kind of symmetry. for sprouts if the board splits into two equal halves you can use nimber addition to show that the first player loses (with the standard "first player unable to move loses" winning condition) 07:07:57 *plays 07:08:05 oklopol: i said no just above... 07:08:13 WHOOOOOOOOOOOPS 07:08:18 *- 07:08:46 i read it as "zzo38: i'm linking this thing here ..." 07:09:10 s/board/game configuration/ 07:09:28 well it said that too... 07:10:48 oerjan: have you skimmed the book? 07:10:56 is it mathematicsly 07:11:03 i should googelate it 07:12:05 no but it's where they use all of that nimber/surreal number theory and stuff so obviously yes 07:12:53 -!- Phantom_Hoover has joined. 07:13:37 But still, are there any shortcuts for searching moves in tsume shogi? There is restriction, such as, first player must give check every turn and has no their own king, second player must delay being checkmated as long as possible. First player loses if they cannot check, and wins if checkmating second player's king. 07:14:06 THE PH LEVEL OF THIS CHANNEL JUST ROSE 07:14:24 it got more basic? 07:14:49 it's funny because Phantom_Hoover is a famous bisexual 07:15:19 zzo38: well i cannot say as i don't know tsume shogi, or shogi for that matter 07:15:23 "There is restriction, such as, first player must give check every turn and has no their own king" 07:15:46 i don't know how to... that sentence 07:16:06 This should already make search algorithm shorter because less moves are possible. 07:17:08 "First player loses if they cannot check" 07:17:13 sounds like a slightly broken game 07:17:24 it sounds like it should be possible to do "tshume chess" as well, then... 07:17:32 *tsume 07:17:46 -!- Phantom_Hoover has quit (Ping timeout: 246 seconds). 07:18:05 oklopol: Tsumeshogi is one player game, the board is set up according to the problem and you have to win in a certain number of moves to solve. Similar to chess problem, a bit. 07:18:07 seriously, how can the first player check on every turn? 07:18:10 oh! 07:18:39 it's sort of like restricted chess problems i assume 07:18:51 oerjan: Yes, like that. 07:18:53 aren't pretty much all chess problems solvable by computer in a micromoment? 07:19:19 of course there _are_ chess problems where you have to check every turn because otherwise the other player gets to do something disastrous with their queen or the like 07:19:38 most problems i've seen are like that 07:19:55 maybe because that's an easy way to tell the player what to do and i've been doing very easy ones 07:20:23 well if it's to be a fun problem, it needs to be solvable by humans, which pretty much means it must be extremely easy for a computer 07:20:56 i agree, chess sucks ass 07:21:04 well 07:21:12 i suppose pretty much all combinatorial puzzles are like that 07:21:48 -!- Phantom_Hoover has joined. 07:22:09 OK NOW IT IS BACK TO ITS HEIGHTENED STATE 07:23:21 actually that's a good question, are there fun combinatorial puzzle type of things that computers can't solve but humans can 07:23:41 Phantom_Hoover: hi 07:25:01 The difficulty in tsumeshogi is to properly program the "futile interposition" rule, although I suppose it could be programmed without such rule, too; or possibly using a restricted form of that rule: that if second player drops pieces which are captured by the same piece checking on the previous turn, which is the same piece still giving check, and this lasts the same way until checkmate, then you rewind to the point where such thing started. 07:25:38 "drops"? 07:25:52 hmm puts somewhere maybe 07:26:27 zzo38: that doesn't sound at all hard to program 07:26:28 oklopol: I mean a piece from off of the board is placed on the board in a vacant position. This is sometimes called "drops". It is a rule in shogi, that chess doesn't have. 07:26:50 oklopol: Yes, it is why I made this restricted futile interposition rule, to make it easy to program. 07:27:17 oh sorry i only read parts of your message 07:27:24 what's the actual rules? 07:27:25 asref9kj0oiae 07:27:26 *ruel 07:27:27 *rule 07:29:51 Jesus Star Control 2 AI vs AI matches are so stupid. 07:29:54 oklopol: I am not exactly sure on the actual futile interpositon rule, actually. But, basically, it is in case you interpose the check and it doesn't help by changing situation to something different, then it is not allowed. See this: http://zzo38computer.cjb.net/img_13/futile.png The piece in the corner is "angle mover" moves like the bishop. The one next to it is "dragon king", like a rook or king. If you move, they can interpose. 07:30:01 Phantom_Hoover: hi 07:30:09 elliott, hi. 07:30:13 (This is, moving causes discovered check in this case.) 07:30:32 It's literally as if Zap Brannigan pilots the lighter ships when they're up against heavies. 07:32:16 :SD 07:32:31 that zappie is one famous bisexual 07:32:32 -> 07:32:40 Dropping on the diagonal blocks check. Moving down doesn't help (you cannot capture your own pieces). If you move to the right, interposing means if they interpose is futile because you can capture opponent's dragon king, gives check again, interposing that check can be captured and is checkmate (your silver general is next to it, guards it). 07:33:00 See? Rule of futile interposition is very confusing. 07:33:03 Be fair. 07:33:14 He's also a famed military tactician. 07:33:56 oklopol: Do you see what I mean, now? 07:35:49 But yes, once the giant laser death frigate appears the other team appear to go for his "clog the enemy cannons with wreckage" tactic. 07:37:06 Phantom_Hoover is a famous bisexual 07:37:09 no wiat 07:37:13 famous gay vampire 07:37:15 mixed my lists up 07:42:11 Restricted futile interposition rule should be easy to program, not even necessary to try all the moves from there. It can simply check all positions in that line. The only checking pieces that can be interposed in this way is: fragrance chariot, flying chariot, angle mover, dragon king, dragon horse. However, it is also necessary to try promotion if applicable, so this is a slight complication (but not too much). 07:42:58 Phantom_Hoover is ignoring my /msgs because he is a nazi.tell your frends 07:44:57 hello #esoteric. Phantom_Hoover is ignoring elliotts /msgs because he is a nazi.tell your frends. 07:45:10 yay we are yor frends 07:45:59 elliott, dammit I warned you about getting me labelled a Nazi. 07:46:07 yes i recall you saying 07:46:10 don't tell everyone i'm a nazi 07:46:14 because they will judge me 07:46:15 because i am a nazi 07:46:48 i do nazi the problem 07:47:01 lol that is funay 07:47:25 now if it were also original it'd be something 07:47:43 However, interposition is not always futile, sometimes it is not the entire sequence which is then checkmate because it is possible to make other things half-way through to change stuff. 07:48:11 Such as, king's moves. 07:49:24 Repeatly capturing interposing piece does not change whether or not king can move, though. 07:52:49 Hmm... IPv4 allocation rate on ipv4depletion site is falling pretty rapidly. It was about 2.80 on last Friday. Now it is 2.15. 07:56:41 Hah (reding old comment entries in Huston's IPv4 address report)... "The uncertainty of this September date is +/- 3 months, so that within a 95% confidence level APNIC will exhaust its address pools sometime between June 2011 and December 2011.".

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. 11:33:31 thank you for that definition. 11:34:49 * Sgeo__ is not a single-language kind of guy 11:35:00 I keep wanting to be for some weird reason 11:35:10 But the siren call of new languages.. 11:35:36 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. 11:36:26 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. 11:44:33 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. Ce 11:44:47 crystal-cola: yeah, I can't read French and I don't give a shit about Ayn Rand. 11:52:58 Gauss shaves both himself and Bertrand Russell. 11:53:48 crystal-cola: are you a markov chain bot? 11:53:58 For Gauss, correlation implies causation. 11:54:34 Gauss can trisect an angle with a straightedge and compass. 11:54:46 gauss facts. wonderful. 11:55:37 is this like Chuck Norris but with Gauss and math? 11:57:38 A Malament–Hogarth (M-H) spacetime, named after David B. 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 11:57:51 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.

15:15:50 awesome math projects 15:15:54 like what 15:15:58 well my five hundred and ten byte forth almost has a compiler... 15:16:02 I learned a bit about algebraic topology 15:16:21 what does the number of bytes mean? 15:16:27 i'm trying to characterize the CA commuting with a given bipermutive automaton 15:16:37 machine code. it's a standard-PC-architecture boot sector. 15:16:39 no dependencies. 15:16:48 well, i use an assembler. but no dependencies in the result. 15:16:49 oh that's cool 15:17:05 we did linear ones with a uni friend and we have a small result that applies to all 15:17:13 i say forth, it's barely anything like forth because i don't care how semantically ridiculous i make it 15:17:16 as long as it's small 15:17:23 And TC, right? :P 15:17:27 I don't know the terminology about automatons 15:17:30 Gregor: On a PC? :P 15:17:43 elliott: TC-BOUNDED-MEMORY BLURP WELCOME TO ENGLISH 15:17:54 crystal-cola: permutive CA = changing any single value in the neighborhood used changes the output 15:18:03 Gregor: Well, no, that is not TC at all :P 15:18:20 elliott: Yes yes and the universe has bounded matter so we DEAL WITH IT. 15:18:21 When you're at the asm level, it's a pretty major distinction, because you pretty explicitly say "And this address is a WORD". 15:18:26 Not so with e.g. Python. 15:18:28 so if two configs differ in exactly one cell, on the nth step in the orbit they differ in the nth cells in both directions from that point 15:18:36 Gregor: Also, you don't know that :) 15:18:43 erm, assuming neighborhood {0, 1} 15:18:57 elliott: Yes I do, I'm omniscient! 15:18:58 and i don't know anything about algebraic topology, except that it's apparently really really awesome 15:19:18 it seems like a good idea but the proofs are horrible 15:19:26 I think it's because the book I looked at sucks 15:19:35 crystal-cola: oh and here linear just means you have Z_n as the states, and the rule must compute a linear combination of what it sees in the neighborhood 15:19:38 crystal-cola: how did that category theory go 15:19:53 commutation just means F(G(c)) = G(F(c)) for all configs 15:19:59 I don't know what you mean? I typed out a bunch of shit then deleted it 15:20:19 deleted it? why 15:20:28 it's useless 15:20:39 I learned about cones and direct limits though 15:20:47 might not be useless to everyone. 15:21:16 you should put lots of old code you've written up on the web 15:21:31 it was just the way you phrased it 15:23:03 oklopol: so there is a characterization for linear ones already? 15:23:15 crystal-cola: yes, proven by me and a uni friend 15:23:32 ouch reddit is still down 15:23:34 wwhat sort of description is it? 15:23:37 well, at least for n = prime, otherwise the rule may not be permutive 15:23:48 crystal-cola: they're all linear or affine (affine = linear + constant) 15:24:06 it's obvious that linear ones commute with linear ones 15:24:16 but that nothing else does needed a small trick 15:24:29 (essentially nothing else) 15:24:50 -!- lament has joined. 15:24:51 did you write a paper on it? 15:25:41 not before we solve the affine ones at least 15:25:47 (assuming that's as easy) 15:26:01 okay 15:26:33 in the meantime i'm publishing other stuff 15:27:05 which is also pretty awesome, i proved the age old conjecture that NFA = FNFA which has been open for 20 years and thought about by at least 4 persons 15:27:20 wow 15:27:42 not really :D 15:28:28 Wow a complexity class that isn't mentioned on complexity zoo 15:28:41 which one's that 15:28:50 oerjan: remember left sets? 15:29:05 What is FNFA? 15:29:24 i realized the other day that it's trivial to prove that there are no sparse NP-complete sets with respect to *many-to-one* reductions 15:29:31 i'd love to prove this at some point 15:29:31 um, argh 15:29:39 oerjan: i'm not sure i've even mentioned them 15:30:01 i remember the name 15:30:21 crystal-cola: FNFA is what i call the class of picture languages accepted by nondeterministic finite state automata that walk on the cells of given pictures, and are allowed to exit their domain 15:30:25 NFA the same but not allowed 15:30:59 why are they equivalent? 15:31:08 oerjan: okay, well in any case i'm sure my explanation was rather unclear last time 15:31:14 crystal-cola: i don't have a short proof 15:31:29 ok 15:31:30 but i have two not that long proofs 15:31:42 i can link the article if and when i get it published 15:34:21 it must feel good proving a theorem nobody proved before 15:35:03 it probably would if a large amount of people had actually tried and failed 15:35:11 i've just picked up random stuff from age old articles 15:35:24 (and the handbook of formal languages) 15:35:40 (but who the fuck has read the last book anyway) 15:36:08 that reminds me ...

F. Inition 16:00:23 a very clever guy 16:00:25 yes 16:01:39 anyhow we now define the left set as Left(L, A, p) = {(x, y) | y \in \Sigma^p(|x|) and exists w such that y <= w, (x, w) in A} 16:01:58 so take A and close the right sides by lexicographic smallerness 16:02:14 then note: Left is in NP 16:02:44 this is a theorem by O.

17:26:37 yep? 17:26:38 :D 17:27:23 let's just say AAAAAAAAAAAARGRHGHRARG 17:27:29 :DD 17:28:05 -!- cheater99 has joined. 17:30:37 oklopol: summon ph plz 17:30:39 with like 17:30:40 magic 17:30:56 ph: stop being such a famous bisexual 17:32:31 -!- Phantom_Hoover has joined. 17:32:38 Phantom_Hoover 17:32:41 you stopped being a famous bisexual 17:32:44 i 17:32:49 almost had a heart attack 17:33:06 :D 17:33:07 a skeleton 17:33:10 oh 17:33:11 jumped in front of me 17:33:12 thort cuz of ph 17:33:14 not ph 17:33:23 oklopol: if this was the server we'd come and give you armour and protect you 17:33:26 but it isn't so hahahahahah die 17:33:51 holy shit, i can't do shit to that thing 17:33:51 :D 17:33:57 oklopol: do you have a: sord 17:34:00 yes 17:34:00 or a: armor 17:34:05 and a: armor?

absolutely, but there's still monsters underground 17:38:39 a relief? fuck yes 17:42:17 hahaaa that was fun, survived at least a minute, an arrow going past every 2 seconds :D 17:42:31 then i dropped into a hole, couldn't see anything 17:43:20 -!- asiekierka has joined. 17:54:43 -!- cheater99 has quit (Ping timeout: 260 seconds). 17:56:02 so i finally found back and jumped in the dungeon, and there were no monsters. so i was alone with a monster spawner and couldn't get back up 17:56:04 that was... fun 17:56:46 :D 17:58:01 i also had no dirt or anything because i didn't know there really was a monster spawner and didn't want to lose anything if i die 17:59:24 lose all that precious dirt 17:59:37 yeeeeeeeeeeah 17:59:39 you realise you can get stuff back for about five minutes 17:59:41 if you run quick 17:59:43 in retrospect, ... 18:00:08 ah yeah jump back in the monster spawner hole 18:01:44 :D 18:01:46 good idea 18:03:56 Vorpal: how would you do an "are you sure?

More than one bone will need to be used on the wolf in most cases. Bone Meal cannot be used to tame wolves. 18:12:35 Vorpal: except it _isn't_ 18:12:43 elliott, it is unless you quote them 18:12:44 show me a bash version where, with proper quoting, test fails on empty arguments 18:12:46 of course it is 18:12:48 if you don't quote them 18:12:51 they're not empty arguments 18:12:54 it's just whitespace 18:12:55 quite 18:12:59 does nobody _understand_ how the shell works? 18:13:06 that's an argument against the shell's syntax, not test 18:13:12 elliott, indeed. 18:14:30 im watching this guys videos about how angles and stuff are wrong 18:14:51 http://web.maths.unsw.edu.au/~norman/views2.htm 18:15:27 do you ever listen to people who say things are right 18:15:55 heh 18:16:09 "The `Axioms' are first of all unintelligible unless you are already a trained mathematician." 18:16:16 yep, that's relevant to the foundation of formalised mathematics, absolutely 18:16:18 yeah anti-axiomatics is kind of a cool view 18:16:25 not really? 18:16:54 -!- oerjan has quit (Quit: Good night). 18:17:13 elliott, erm, the attitude that "deduction from axioms is all that is necessary" is not a very constructive one. 18:17:28 every does math based on axioms, or at least they think they are doing so 18:17:30 Phantom_Hoover: when did i say that 18:17:57 crystal-cola: let me summarise that article for you 18:18:12 "this is a bit unintuitive at first glance, because i said so. i bet you don't understand it. therefore it's wrong" 18:18:18 hehe 18:19:59 he has some good points abuot angles 18:20:09 you can basically do trigonometry without calculus 18:20:14 so why not do that? 18:20:40 waste of time? 18:20:43 I like the way he says "the axiom of infinity is clearly rubbish, it doesn't define what an infinite set is" when the reason it doesn't do that is because he stripped out the definition. 18:21:28 I mean normal things like angles and trigonometry can only be rigorously done in terms of calculus 18:21:41 but you usally learn these things before learning enough calculus to justify them 18:21:45 ...they can? 18:22:00 so if you are going to do trigonometry at all why do it in that way? Since there is an easier way 18:22:12 one that isn't founded on more advanced mathematics 18:22:21 you mean: one that isn't founded on anything formal at all. 18:22:31 I don't think crystal-cola understands how rigour works. 18:22:38 both can be made completely rigorous 18:22:49 the only difference is how much work it takes 18:23:42 " you can basically do trigonometry without calculus" <<< because it's no fun 18:24:22 " ...they can?" <<< what? 18:24:46 I didn't know that, but I suppose it makes a bit of sense. 18:24:58 crystal-cola: another difference is you're not doing math, eventually you might disagree with someone. 18:25:05 oklopol, erm, what is it with you and needing everything to be completely rigorous? 18:25:17 oklopol: ?? 18:25:47 Phantom_Hoover: er, because not being rigorous is not fun? 18:25:49 i just said it 18:26:03 real ultimate rigor comes in #agda 18:26:12 I'm... not sure that's at all universal among mathematicians. 18:26:15 tedium is fun! 18:26:20 tedium is not at all fun 18:26:24 I love it 18:26:28 well you're crazy 18:26:31 lol 18:26:33 just kidding 18:26:33 :D 18:26:38 me too 18:26:40 what do you mean oklopol 18:26:42 I'm not even sure it's typical. 18:26:42 I like automatinc/abstracting over tedium 18:26:44 you can love whatever you want 18:26:53 crystal-cola: mean by what? 18:26:56 19:24 < oklopol> crystal-cola: another difference is you're not doing math, eventually you might disagree with someone. 18:27:05 are you talking about axiom-free mathematics? 18:27:13 ah, well that's the reason we do math based on axioms: people cannot disagree 18:27:19 that's lovely 18:27:30 people can disagree... if at least one of them is wrong 18:27:34 I can reject your axioms 18:27:39 well i've never ever seen that happen 18:27:41 and tell you you're living a lie 18:27:52 remember when crystal-cola said the trolling was over :D 18:27:53 * copumpkin is an ultrahyperfinitist 18:27:58 copumpkin: you can reject my axioms all you want, i'm not claiming they are correct 18:28:04 copumpkin: i'm so ultrafinitist I don't even believe in two 18:28:08 I am therefore a solipsist 18:28:10 oklopol: yeah, but I can try to make you feel bad for wasting your life! 18:28:18 and all my sentences, of which there is only one, are composed out of one word with one letter 18:28:36 for the purpose of this kind of arguments, a mathematician should be a formalist 18:28:40 *every 18:29:01 elliott: why do you always talk about finitism? 18:29:08 * copumpkin is an ultrahyperfinitist 18:29:11 copumpkin is the one that brought it up 18:29:18 you always talk about it 18:29:22 no i don't 18:29:26 yes you do 18:29:32 i see the ban taught you nothing 18:29:46 check the logs if you don't remember 18:29:46 * copumpkin is an avid follower of norman wildberger 18:30:19 crystal-cola: in any case that's not my actual argument against axiom-free geometry, my argument is i don't get anything out of it, because i don't know what we're talking about. 18:30:30 elliott: You talk about finitism all the time, I wonder why because you're obviously not actually a finitist 18:30:37 crystal-cola: no, I do not 18:30:39 elliott: Basically you're trolling. Why do you keep doing it? 18:30:54 shame oerjan isn't around right now. 18:31:05 well, i get something out of it 18:31:23 14:19:52 I'm starting the Order of Ultrafinitist Programmers, we code exclusively in lookup tables 18:31:24 but it doesn't have that taste of exciting sexiness that set theory based math has 18:31:26 yesterday 18:31:32 oklopol: in axiom-free geometry, wouldn't everything be false? 18:31:34 You brought up finitism 18:31:37 it seems a little pointless and degeneraet 18:31:38 crystal-cola: please just shut up. 18:31:39 *degenerate 18:31:42 or am I missing the point? 18:31:46 elliott: because I proved you wrong? Okay 18:31:57 ais523: i assume axiom-free geometry means doing geometry like kids do it 18:32:09 oklopol: oh, I see 18:32:17 but kids have lots of axioms, much more than just four or five 18:32:26 sure 18:32:28 everything they know is treated like an axiom, pretty much 18:32:34 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. 18:34:56 crystal-cola: there is no serious discussion, there is just you being a dick and trolling again, whether intentionally or not 18:35:02 ais523: but the point is axiomatizing geometry directly is really tedious, and it was not long ago that they discovered that a crucial axiom (which had been used tons of times) was missing from the usual axiom set; and doing it the calculus way, talking about R^n, requires a lot of (")advanced(") math 18:35:13 elliott: wrong 18:35:17 and it's something pretty much everyone agrees with 18:35:31 without any sort of explicit axioms 18:35:51 oklopol: what axiom was that? 18:36:02 crystal-cola, shut up. 18:36:25 ais523: i don't recall, it was mentioned in our geometry course (the least formal course we have in the whole university) 18:36:32 crystal-cola: fsvo wrong 18:36:44 I guess it works when you /ignore everyone who disagrees, though 18:36:52 something pretty simple like if you have a point and a line, there's a closest point on the line or something 18:36:58 what 18:37:06 crystal-cola: crystal-cola, shut up. 18:37:15 okay I'll /ignore you too 18:37:23 i'm so surprised 18:37:24 stops us arguing as a bonus 18:37:29 how long until you're ignoring three fourths of the channel again 18:37:32 maybe i'll see if i can find it 18:39:01 wow, this system is so bizarrely broken that /etc/mtab was replaced by NetHack's helpfile 18:39:13 ais523: :D 18:39:14 ...what is /etc/mtab normally? 18:43:43 -!- azaq23 has quit (Quit: Leaving.). 18:47:07 oerjan: for your logreading pleasure: a single step of the algorithm splits all the intervals in two, which means that in a polynomial amount of steps w.r.t. |x| (because strings are of length p(|x|)), we have that every interval is of size 1. of course, i haven't really told you why we're writing an algorithm, maybe i'll do that later. 18:49:15 -!- sebbu2 has joined. 18:49:16 -!- sebbu2 has quit (Changing host). 18:49:16 -!- sebbu2 has joined. 18:52:11 -!- sebbu has quit (Ping timeout: 246 seconds). 18:52:12 -!- sebbu2 has changed nick to sebbu. 18:52:48 "Sometime in their second or third year, a dramatic change happens in the training of aspiring pure mathematicians. They start being introduced to the idea of rigorous thinking and proofs, and gradually become aware that they are not at the peak of intellectual achievement, but just at the foothills of a very onerous climb." 18:53:12 second/third year? lol 18:53:57 I never got introduced to anything rigorous in my math courses 18:54:13 it's sad 18:54:15 you've mentioned 18:54:19 which is fine, I am able to supply my own rigor 18:54:32 but I do think "normal" students cannot 18:55:28 Do you suppose the curriculum at this point has time or inclination to return to the material they learnt in public school and high school, and finally organize it properly? When we start to get really picky about logical correctness, doesn't it make sense to go back and ensure that all those subjects that up to now have only been taught in a loose and cavalier fashion get a proper rigorous treatment? 18:55:31 Isn't this the appropriate time to finally learn what a number in fact is, why exactly the laws of arithmetic hold, what the correct definitions of a line and a circle are, what we mean by a vector, a function, an area and all the rest? You might think so, but there are two very good reasons why this is nowhere done. 18:55:47 they don't teach people what functions actually are? :D 18:55:58 i think this guy's problem is he went to a zoo instead of a university 18:56:00 oklopol: Nobody ever taught me what a function was 18:56:22 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 18:56:44 a function from X to Y is a subset S of XxY such that for all x, there is exactly one y such that (x, y) is in S, this is one of the first sentences in every book and lecture notes 18:56:58 oklopol: I don't think I've been formally taught what functions are either 18:57:08 but I picked it up quite quickly (it helps that my father knew the actual definition) 18:57:23 and in a computer science department, if you're missing something that basic you ask someone and learn it very quickly 18:57:57 well i haven't seen a more tedious definition than that, that is, most definitions are based on set&tuple theory instead of set theory 19:00:18 "The first reason is that even the professors mostly don't know! They too have gone through a similar indoctrination, and never had to prove that multiplication is associative" 19:00:23 what 19:00:25 :D 19:00:38 I only had my first real math class this year. 19:01:46 "Ask them just what a fraction is, or how to properly define an angle, or whether a polynomial is really a function or not, and see what kind of non-uniform rambling emerges!" 19:01:48 what the fuck 19:01:56 that was weird 19:02:03 someone disagreed with me in #haskell and I didn't get banned 19:02:05 "whether a polynomial is really a function or not" 19:02:10 ... 19:02:23 Dammit, oerjan's not here. 19:02:31 When is he when you need someone banned. 19:02:39 this stuff is explained in painstaking detail in like 4 courses here 19:03:14 ...are they not functions? 19:03:16 oklopol: yeah seriously I think you just go to an exceptionally good university 19:03:26 normally none of this stuff gets talked about 19:03:33 Phantom_Hoover: the problem is they can be both. 19:04:00 when you have say a ring you can define a formal polynomial ring 19:04:13 but then obviously you can also associate a function to each of those polynomials 19:04:21 so mind is blown 19:05:01 elliott: do you have any idea how to remount / readonly on a system while it's running? 19:05:10 ais523: can't you remount /? 19:05:14 mount -o ro,remount / or whatever 19:05:16 this is in a throwaway VM, so it doesn't matter if it screws up 19:05:20 I tried that, it said "/ is busy" 19:05:25 which was pretty inevitable, really 19:05:26 ais523: force it 19:05:29 ah, aha 19:05:35 hmm, _can_ you force it 19:05:37 lemme check 19:05:42 yep, I could 19:05:55 hmm 19:05:55 crystal-cola: from what i understand we're better than average, but we don't even get in the top 100. 19:05:56 ais523: how? 19:05:59 -f 19:06:00 I see no force options in mount(one) 19:06:03 or was it top even more 19:06:08 ais523: er 19:06:14 -f, --fake 19:06:14 Causes everything to be done except for the actual system call; if it's not obvious, this ``fakes'' mounting the filesystem. This option is useful in conjunc‐ 19:06:14 tion with the -v flag to determine what the mount command is trying to do. It can also be used to add entries for devices that were mounted earlier with the -n 19:06:14 option. The -f option checks for existing record in /etc/mtab and fails when the record already exists (with regular non-fake mount, this check is done by ker‐ 19:06:15 ah, that's not a force option at all 19:06:15 nel). 19:06:17 ais523: FAIL :) 19:06:32 it doesn't really matter how math is taught 19:06:42 even more amusingly, it seemed to have worked 19:06:43 if you're smart you'll probably prove good theorems no matter what 19:07:11 probably, i wouldn't know 19:07:32 because i'm not smart 19:07:58 oklopol, FFS, stop talking to him. 19:08:56 Phantom_Hoover: sorry, can't please everyone 19:09:18 i have nothing against cc 19:09:20 well not much anyway 19:09:29 probably nothing at all 19:09:30 oklopol: FUCKING CREEPER AMBUSHED ME FROM ABOVE 19:09:35 :\ 19:09:45 must've been one famous bisexual 19:09:47 hmm, only when you work inside someone else's screen(1) do you realise how much you use control-a for start-of-line 19:11:11 'an infinite set is a collection of mathematical objects which isn't finite' xD 19:11:18 what the fuck kind of definition is that :D 19:12:21 an infinite set is a set which is infinite 19:12:26 yes! 19:12:36 not finite, LOL :D 19:12:40 I seem to like the taste of mouthwash 19:12:50 but yeah, that's a good definition right there 19:12:59 oklopol: and a finite set is one without an infinite number of elements 19:13:05 well, finite is probably easier to define than infinite, without circularity 19:13:15 a set is finite if it has no elements, or one more element than some finite set 19:13:24 Have you looked at my unicode identifiers function by the way? I'm pretty proud of its sheer degree of horror :P 19:13:25 no, lemme pull it up now 19:13:25 omg 19:13:25 you are insane 19:13:25 8-D 19:13:34 category of finite sets 19:13:37 Gregor: It's not _that_ much of a horrible hack :P 19:13:37 ais523: infinite sets are usually defined as sets containing a proper subset for which there is a bijection with the original set 19:13:50 oklopol: does that work even without the axiom of choice? 19:13:52 elliott: Later: that's actually just insane enough to feel right at home in Narcissus ;) 19:13:55 Gregor: In a language with an eval that took an AST rather than a string, it might even elegant :P 19:13:58 [asterisk]even be 19:14:10 that definition of infinite set works without choice 19:14:13 ais523: the definition certainly works 19:14:28 elliott: Uhh, in a language with an eval that took an AST instead of a string, it wouldn't work. 19:14:29 oklopol: I mean, it might mark some infinite sets as not infinite 19:14:37 due to the inability to chose an arbitrary such subset 19:14:39 elliott: Unless it did identifier validation over the AST for no real reason. 19:14:46 Gregor: Sure it would, if you can construct an identifier node from a string. 19:14:51 In fact, you'd just do that X-D 19:14:55 you have an axiom that gives you one element, and you have an axiom that lets you drop everything except that 19:15:02 oklopol: Infinite sets are those which have at least as many elements as the natural numbers. The natural numbers are defined as the smallest infinite set. 19:15:34 but about this stuff, the prof is certainly right in my case. 19:15:48 which is good for him because it's his main point 19:15:56 anyway axiom-free mathematics is to just brush aside since axiomatization is "solved". Look at Eulers papers 19:18:29 " oklopol: Infinite sets are those which have at least as many elements as the natural numbers. The natural numbers are defined as the smallest infinite set." <<< who says there's nothing between |N| and the finite sets though? :) 19:18:47 say a subset of N that's not finite but not in bijection with N either 19:18:48 oklopol: nobody. that's the magic of mathematics. 19:19:05 oklopol: why CONSTRAIN yourself? 19:20:00 it's not very hard to prove with the tools i have, but the tools i have are not what are usually taken as the axioms 19:20:01 "subsets of N" is a difficult notionn 19:20:25 crystal-cola: in what sense? 19:20:27 consider permutations of N, is a subset of N just the first n elements of a permutation? 19:20:50 not with my definitions 19:20:54 that's exactly the finite sets 19:20:57 *definition 19:21:03 erm, finite subsets 19:21:25 all subsets of N are finite, because they only have SOME of its elements, and N is the smallest infinite set 19:21:26 qed 19:21:35 well even in the finite case it's awkward becuase of "wild" permutations 19:22:02 what are those? 19:22:36 no single permutation is all that wild 19:22:51 1 is bijected to some n_1, 2 is bijected to some n_2... 19:23:16 http://qchu.wordpress.com/2009/11/05/i-dont-trust-uncountable-sets/ 19:27:17 I guess one of the difficulties is, let S be a subset of N then consider the obvious bijection 1 -> first element of S, 2 -> second element, ... 19:27:32 almost all infinite sets S lead to functions that grow so fast... 19:27:44 much faster than busy beaver 19:27:55 ...and? 19:28:16 fast growing functions are a bitch, ever studied logic? 19:28:29 you have an axiom that gives you one element <--- ah, that's the axiom I was missing 19:28:33 I don't know sets from the axioms 19:28:35 -!- impomatic has joined. 19:28:35 oklopol: exponentiation ain't total don'tchaknow 19:28:44 not much, what's bitchy about fast growing functions? 19:28:52 they're just really difficult 19:29:04 difficult? 19:29:09 the rate of growth of a function is the sort of thing you need stronger and stronger axioms to deal tih 19:29:12 with 19:29:12 what's difficult about them, you don't need to do anything about them 19:29:39 Hi :-) 19:29:43 you just define a subset Y of X as a set such that y \in Y implies y \in X, and see what happens 19:29:43 like you can't prove ackermann terminates in weak logics.. you need something extra 19:29:50 -!- jcp has quit (Ping timeout: 260 seconds). 19:29:52 and the same phenomenon happens all the time throughout 19:30:12 crystal-cola: and what does that have to do with anything?

19:38:29 initial = exactly one arrow from, per object; final = exactly one arrow to, per object 19:38:31 and I'm not entirely convinced your axiom is correct either 19:38:42 what axiom? 19:38:48 the one i pasted?

Think for a few more days, and you will be able to see how to make these statements without any reference to `infinite sets', and that this suffices for Cantor's proof that not all irrational numbers are algebraic. 19:57:46 " 19:57:46 Precisely :P 19:57:58 that's a subtle one 19:58:18 The computable reals are countable if you consider them as computter programs 19:58:23 Vorpal: Yeah, but they have a lot of control circuitry which is supposed to be protected from the INSIDE microwaves, not OUTSIDE microwaves. <-- oh, true 19:58:26 but cantors diagonalization still works 19:58:37 so it all depends if you're "inside" or "outside" the theory 19:58:39 Gregor, so you could make every other nested microwave work 19:58:40 Cantor's microwaved diagonalisation. 19:58:48 Vorpal: lol X-D 19:58:55 X-D 19:58:59 Russian nesting microwaves. 19:59:01 Oh my god we must nest these microwaves for science. 19:59:08 We need to buy some gigantic fucking industrial microwaves. 19:59:25 crystal-cola: sure, but there's something funny about "think clearly", because it means "think about it the way i like to". 19:59:26 TNT IN A MICROWAVE: ??? 19:59:34 heh 19:59:36 Gregor, of course, that is a an obvious logical extension of the theoretical framework for microwave nesting we developed above 20:00:09 TNT IN A MICROWAVE: ??? <-- I think it wouldn't explode.

It would do the usual anti-matter stuff (which isn't boring), but the microwave wouldn't really add anything 20:11:34 elliott, microwave really tiny black holes. 20:11:38 Phantom_Hoover: YES 20:11:43 WHAT WOULD THAT EVEN DO 20:11:45 Phantom_Hoover, what would that do? 20:12:02 That are set up so that they absorb exactly as much mass from the microwaves as they lose to Hawking radiation. 20:12:03 IT SOUNDS SPECTACULAR 20:12:15 CAN YOU GET ANTI-BLACKHOLES, SAY YES 20:12:17 So when you turn your microwave off, OOPS GAMMA RAY EXPLOSION 20:12:21 I WANT TO COLLIDE A BLACKHOLE AND AN ANTI-BLACKHOLE 20:12:24 Phantom_Hoover: X-D 20:12:25 PERFECT 20:12:26 elliott, I think they're equal-opportunities. 20:12:48 Phantom_Hoover: I assume the aforementioned explosion would be fairly devestating. 20:12:50 devastating. 20:13:05 Phantom_Hoover, that is under the assumption that Hawking radiation exists.

20:26:55 I thought you were joking when you said they weren't working, in Agora 20:27:15 ais523: they literally aren't working 20:27:15 also, /why/ would /dev/sda1 stop existing upon doing that? 20:27:21 and who knows, udev sucks 20:27:24 as in, you press them and nothing happens? 20:27:30 yes. one to eight. 9 and 0 work. 20:27:35 i suspect it is one portion of the keyboard matrix. 20:27:38 that has been damaged 20:27:42 yep, sounds like a broken wire or something 20:28:00 I'm going to backup, wipe the drive, and send it off to Apple 20:28:07 they'll almost certainly just send me a new one 20:28:15 as I'm pretty sure getting at the keyboard controller on a MacBook Air is downright impossible 20:28:25 why wipe the drive? so they don't get to see your data? 20:28:37 ais523: well, right now it boots into Linux by default. 20:28:43 ah 20:28:50 you can get 2, 3, and 5 via tab-complete on my name, at least 20:28:50 even if that doesn't void the warranty, it'd sure as hell confuse them 20:29:02 also, it does seem like a fairly reasonable privacy measure to take 20:29:10 especially as they'll copy whatever to the new one 20:29:17 and they'd probably mess up a non-trivial partition table 20:29:21 which would just create more work for me fixing it up 20:32:50 elliott, wouldn't it be easier to just move the hdd? 20:32:56 or ssd 20:32:57 Suggest we all provide elliott with a digit. 20:32:58 as it may be 20:33:04 Alternately: 20:33:13 Vorpal: Not gonna feed the troll. 20:33:28 -!- Phantom__Hoover has joined. 20:33:40 -!- Phantom__Hoover has changed nick to no0123456789. 20:33:41 elliott, actually my question was in ernest, why would apple not just move the ssd over, should be cheaper for them 20:33:51 Oh, them. 20:34:00 Vorpal: Because the SSD chips are printed on to the motherboard. 20:34:07 They may technically be detachable, but it wouldn't be pretty. 20:34:15 Vorpal: do you have any idea how to set all a running system's filesystems to readonly, apart from /dev/shm/ 20:34:20 s/\/$/?/ 20:34:24 ais523: you unmounted /, right? 20:34:26 preferably in a way that doesnt' cause it to crash? 20:34:26 recreate sda[one] 20:34:28 and mount it readonly 20:34:31 that will work 20:34:32 since / is no longer busy 20:34:35 or anything 20:34:36 elliott: yes, I recreated sda1 20:34:40 Vorpal: Because the SSD chips are printed on to the motherboard. <-- oh 20:34:42 but trying to mount / says it's already mounted 20:34:43 ais523: mount -o ro /dev/sda[one] / 20:34:46 hmm 20:34:49 elliott, I was not aware 20:34:55 elliott, dammit I provided you with the numbers at GREAT PERSONAL EXPENSE 20:34:56 ais523: umount -fl // 20:35:00 erm only one / 20:35:05 the force might help beforehand 20:35:11 Phantom_Hoover: THANK YOU 20:35:32 elliott: yes, I recreated sda1 but trying to mount / says it's already mounted <-- what are you doing? 20:35:40 gah, I just screwed up screen somehow 20:35:41 Vorpal: do you have any idea how to set all a running system's filesystems to readonly, apart from /dev/shm/ 20:35:47 reading comprehension 20:35:47 ah 20:35:50 Vorpal: trying to set the filesystem of a virtual machine to readonly 20:35:50 ais523: why are you trying to do this anyway? 20:36:01 ais523, hm... mount -o ro,remount / ? 20:36:06 Vorpal: ... 20:36:08 elliott: so you can rewind just by restoring memory, rather than having to handle the disk as well 20:36:09 ais523, and same for all the other ones 20:36:11 yeah, that's not the first thing we tried 20:36:22 Vorpal: "/ is busy" 20:36:36 ais523, check with lsof to find out what process uses it 20:36:44 Vorpal: apart from EVERYTHING? 20:36:45 ais523: ok, what if you used switch_root? 20:36:51 oh wait 20:36:53 WARNING: switch_root removes recursively all files and directories on the current root filesystem. 20:36:58 elliott, well I assume you are in single user mode? doing it from X is unlikely to work 20:37:11 Vorpal: one: ais523, not me 20:37:13 elliott, it is meant for initramfs 20:37:15 two: what a stupid asumption 20:37:17 assumption 20:37:21 oh right 20:37:32 elliott: wait, why would a command have an option to do an rm -rf --no-preserve-root /? 20:37:38 apart from rm, I mean 20:37:43 and it needs three 20:37:44 ais523: meant for initramfs, like Vorpal said 20:37:50 after creating the real root 20:38:07 Vorpal: yes, all the processes on the system are using / 20:38:13 ais523, the reason is so that the space on the tmpfs that the initramfs makes up can be reclaimed 20:38:13 ais523: here's an idea 20:38:16 ais523: use a bind mount 20:38:24 ais523, writing? 20:38:28 elliott: how would that help? 20:38:31 ais523: mount sda[one] read-only in ~/foo, unmount super-lazy / 20:38:34 ais523: bind ~/foo to / 20:38:37 ais523, read only use doesn't matter 20:38:43 notice you are suddenly :SO HIGH: 20:38:46 ais523, btw why are you doing this? 20:39:03 elliott, I don't think bind mounts nest 20:39:13 ais523, btw why are you doing this? elliott: so you can rewind just by restoring memory, rather than having to handle the disk as well 20:39:20 oh 20:39:26 $ sudo umount -fl / \ umount: /: not mounted \ $ sudo mount -o ro / \ mount: /dev/sda1 already mounted or / busy \ mount: according to mtab, /dev/sda1 is already mounted on / 20:39:37 go go mount! 20:39:59 for bonus points, I found a command that makes sda1 readonly (the actual device), but it seems to be a no-op 20:40:12 ais523: modify mtab 20:40:12 even when I made a 2MB file, in order to get around potential caching problems 20:40:25 ais523, if this doesn't work out, you might want to check out snapshots in lvm. they are COW, and destroying a branch is quick (just discard the copied data) 20:40:31 ais523: delete the sda[one] line 20:40:32 try again 20:40:33 :) 20:40:39 elliott: same error, without the "according to mtab" 20:40:52 ais523: unmount /proc, create a /proc directory, copy mtab to /proc/monuts 20:40:53 mounts 20:40:56 that was inevitable, surely 20:41:05 elliott: that's... brilliantly evil 20:41:06 WIZARDRY AT MY FINGERTIPS 20:41:14 ais523: I think it's probably the syscall itself failing, but worth a shot :D 20:41:20 $ sudo umount /proc 20:41:21 umount: /proc: not mounted 20:41:23 ais523: unmount /proc, create a /proc directory, copy mtab to /proc/monuts <-- aieee! 20:41:24 lol 20:41:26 just do it manually then 20:41:28 sudo rm /proc/mounts 20:41:32 sudo cp /etc/mtab /proc/mounts 20:41:42 indeed, /proc is an empty directory 20:42:01 but same error even after I put a file in it 20:42:06 hmm 20:42:12 you have a c compiler? 20:42:41 I think so, but this is getting increasingly insane 20:42:45 ais523, you could edit /etc/fstab to mount stuff readonly. And remove any remounting to rw from the system startup scripts. Then reboot. 20:42:47 that would work 20:42:47 are you going to suggest just calling the syscall by hand? 20:42:55 MNT_FORCE (since Linux 2.1.116) 20:42:55 Force unmount even if busy. This can cause data loss. (Only for NFS mounts.) 20:42:55 MNT_DETACH (since Linux 2.4.11) 20:42:55 Perform a lazy unmount: make the mount point unavailable for new accesses, and actually perform the unmount when the mount point ceases to be busy. 20:42:55 MNT_EXPIRE (since Linux 2.6.8) 20:42:56 Vorpal: that involves a reboot, which defeats the point of the exercise 20:42:58 Mark the mount point as expired. If a mount point is not currently in use, then an initial call to umount2() with this flag fails with the error EAGAIN, but 20:43:01 marks the mount point as expired. The mount point remains expired as long as it isn't accessed by any process. A second umount2() call specifying MNT_EXPIRE 20:43:04 unmounts an expired mount point. This flag cannot be specified with either MNT_FORCE or MNT_DETACH. 20:43:06 ais523, what exactly *is* the exercise? 20:43:07 ais523: try doing 20:43:09 umount[two] with all those flags 20:43:11 then again 20:43:13 with the same flags 20:43:15 ais523: then try mounting with the mount tool 20:43:16 Vorpal: making the FS readonly on a running system 20:43:19 note: the mount binary itself may disappear 20:43:20 it really shouldn't be this hard 20:43:27 ais523, go to single user mode, you can do it then 20:43:39 just set the runlevel to 1 with telinit? 20:43:55 mmm that should work 20:44:02 ais523, in fact you can do it as long as nothing has anything open for writing on that partition 20:44:08 ais523: can i have ssh access, this sounds like great fun 20:44:14 elliott: not mine to give 20:44:14 ais523, lsof will tell you if it is open for reading or writing 20:44:19 ais523: lame 20:44:20 well, I did sudo telinit 1 20:44:26 and now it doesn't respond to the keyboard 20:44:47 -!- KingOfKarlsruhe has quit (Quit: ChatZilla 0.9.86.1 [Firefox 3.6.16/20110319135224]). 20:45:01 ais523: Have errors=remount-ro on, and then force some sort of an error on the filesystem? 20:45:12 fizzie: I was beginning to think along those lines 20:45:25 ais523, uh? 20:45:45 fizzie, that is ext-specific isn't it? 20:45:55 fizzie: I was thinking that myself too 20:45:59 since I've had my FS rendered read-only before 20:46:06 ais523: even on a vt? 20:47:42 Vorpal: Yes. Well, at least ext2 and such support it; some others might too for all I know. 20:48:09 fizzie, I was thinking about jfs, xfs and so on 20:48:19 speaking of which, is brtfs any good yet? 20:48:33 (good implies stable here) 20:49:22 -!- KingOfKarlsruhe has joined. 20:49:29 It's controlled by Oracle, so it'll never be (mentally) stable. 20:53:42 "Btrfs supports a very limited form of transaction without ACID semantics: rollback is not possible, only one transaction may run at a time and transactions are not atomic with respect to storage." 20:53:42 wtf 20:53:58 In what way is that transactions at all :P 20:54:43 haha 20:54:52 isn't that a semaphore? 20:54:55 rather than a transaction? 20:55:05 Is it even a semaphore? Sounds like a mutex :P 20:55:07 the two concepts are rather different 20:55:12 yeah but if Oracle says it's a transaction 20:55:14 who will doubt :D 20:55:21 Gregor: a mutex is a boolean semaphore, isn't it? 20:55:25 ais523: Yuh 20:59:56 `run echo 'foo() { echo $1 }; foo bar' | csh 20:59:57 No output. 20:59:57 There is this much-circulated btrfs discussion, https://lkml.org/lkml/2010/6/18/144 -- but that's almost a year old and I make no claims to the truthfulness of it. 21:00:02 `run which csh 21:00:04 No output. 21:00:09 Of course not, why the hell would I have csh :) 21:07:08 -!- azaq23 has quit (Ping timeout: 258 seconds). 21:07:15 "if you're on 2.6.32 or older 21:07:15 You should consider upgrading.
