00:33:19 <kmc> Sgeo: you're not allowed to "use" things in Java, only "leverage" them
00:41:53 <Arc_Koen> ok, someone has implemented Conway's game of life, and someone else a brainfuck interpreter... *in spacechem*
00:41:53 <lambdabot> Arc_Koen: You have 1 new message. '/msg lambdabot @messages' to read it.
00:41:58 <lambdabot> oerjan said 2h 32m 30s ago: doesn't your brainfunct truth-machine have an off-by-one error? i.e. loops on '0' rather than '1'

00:44:30 <Arc_Koen> oerjan: I wrote an interpreter for brainfunct and I checked the truth-machine, it was working
00:44:41 -!- copumpkin has joined.
00:44:49 <oerjan> i wrote another interpreter and it didn't :/
00:45:01 <Arc_Koen> hmm maybe the functions are numbered differently
00:45:53 <oerjan> > length "///////////////////////////////////////////////"
00:46:15 <Arc_Koen> maybe I just copypasted it wrong
00:46:21 <oerjan> there are 47 initial /'s, so the .@ function following them is on 48
00:47:14 <Arc_Koen> and my interpreter just looped on 0
00:49:24 <Arc_Koen> funny thing, the brainfunct program is tail-recursive but my interpreter doesn't acknowledge that, because of the 'for' loop
00:49:55 <Arc_Koen> I guess I should fix that by taking the last step out of the for loop
00:50:17 <oerjan> should I/O be binary or text-mode?
00:51:06 <Arc_Koen> > length "///////////////////////////////////////////////"
01:01:21 <Arc_Koen> weird, it should be tail recursive now, but it still says Stack_overflow
01:08:45 <zzo38> G. Steele seems to be much better than my current PG (Cahill) but they are too expensive.
01:09:35 * oerjan puts his haskell interpreter on the wiki page
01:10:22 <Sgeo> Wait, what, a Haskell interpreter in an esolang?
01:10:36 <oerjan> i distinctly expected that comment
01:10:49 <oerjan> but no, it's brainfunct in haskell
01:10:51 <zzo38> Then your expectations are correct.
01:11:02 <Sgeo> I honestly was confused, not trying to make a joke. I am unconfused
01:11:27 * Arc_Koen fought hard not to make the joke
01:11:46 <Arc_Koen> so, hum, some guy wrote a brainfuck interpreter in spacechem
01:11:51 <oerjan> and i couldn't resist keeping it in
01:12:06 <oerjan> Arc_Koen: btw i support nesting
01:12:22 <zzo38> I have made one Haskell program on esolang wiki on its own page; the raw contents of the page are a valid Haskell program and the page can also be read like other wiki page. Such thing can be done with Haskell.
01:12:23 <oerjan> in theory anyhow, i haven't tested except by modifying the cat
01:12:40 <Arc_Koen> I have no idea how useful nesting can be, though
01:13:15 <Sgeo> " This is great news for you, and bad news for malware generators, because:"

01:14:08 <Arc_Koen> oerjan: Haskell sounds like a very hard to read ocaml
01:14:53 <kmc> ocaml syntax is fugly
01:14:58 <kmc> haskell syntax is more complicated but nicer
01:15:41 <kmc> zzo38: is it Literate Haskell?
01:16:10 <zzo38> This game is difficult I only have one C so if he is injured, I am probably going to lose.
01:16:31 <kmc> i just checked and Literate Haskell is in the Report
01:16:32 <zzo38> kmc: Yes, it is Literate Haskell. You can embed Literate Haskell in HTML, XML, MediaWiki, TeX, and other formats without much difficult.
01:16:35 <kmc> i thought it wasn't
01:16:47 <zzo38> kmc: Well, now you know.
01:17:13 <kmc> and knowing is haf the battle
01:17:42 <Arc_Koen> oerjan: I'm not sure brainfunct is equivalent to brainfuck, actually
01:17:59 -!- evincar has quit (Read error: Connection reset by peer).
01:18:52 <Arc_Koen> it lacks a test instruction - the truth-machine is a good example of this lack
01:20:18 <kmc> someone should start a band named The Regents of the University of California
01:20:33 <zzo38> kmc: Are you going to do so?
01:21:16 <oerjan> Arc_Koen: you can simulate brainfuck with a smaller cell size, i think
01:23:08 -!- evincar has joined.
01:23:20 <oerjan> let's say you need k branch points in the program, and your brainfuck has cells 0 ... n-1, then you can add n*i where i is the number of your branch
01:23:43 <oerjan> may need some off by one tweaking
01:24:32 <Arc_Koen> hummmm I'm pretty sure I did not understand what you just said
01:24:33 <oerjan> and for this you need brainfunct cell values 1 .. n*k
01:25:45 <Arc_Koen> but it is 3 in the morning and I'm tired and I have to get up in 4h and a half so I'll read the logs tomorrow to try to understand

07:41:42 <Sgeo> Although... I do think I'd prefer my code to be usable from/with proprietary code, so I'd probably lean more BSD-ish. But EPL might be better than GPL for that goal
07:41:48 <Sgeo> (the goal that GPL has)
07:42:20 <impomatic> I like the fact the BSD license is short.
07:43:37 <Sgeo> Hmm, if Clojure, and about a million Clojure libraries, are under the EPL, does that make Clojure unsuitable for making proprietary programs?

13:51:10 <mroman> Universities don't teach that.
13:58:05 <itidus21> if you invest more time and energy in security systems, the people breaking the systems will simply adapt, and find new vulnerabilities
14:01:54 <itidus21> universities aren't going to spontaneously change, students aren't going to spontaneously change, i don't forsee anything changing
14:06:44 <Jafet> Software development involves writing software to address the problems found in previous software development.
14:16:34 <FreeFull> Sgeo: Same how buffer overflows are still the most common kind of vulnerability
14:16:58 <FreeFull> Well, I guess SQL injections aren't as fundamental
14:17:23 <itidus21> i guess what im wondering is whether it is important to place blame, and also who is to blame for sql injection vulnerabilities
14:17:44 <itidus21> or is the whole system to blame
14:18:02 <FreeFull> itidus21: Clearly the people who created SQL are to blame
14:18:15 <FreeFull> How dare they invent database technology
14:18:43 <itidus21> basically i don't think blame is a perfect system, it's more like garbage collection

14:20:57 <olsner> I think the root problem is that too many programmers just don't know or care enough about security
14:21:17 <itidus21> olsner: but what is the cause of that :D
14:21:24 <itidus21> rather, what is that a symptom of?

16:12:18 <atriq> Not much unless you're in the US
16:17:10 <itidus21> the best way to find out the difference between a biscuit and a cookie is to get both and compare them
16:17:48 <itidus21> you might like the one you eat first more
16:17:55 <itidus21> because it satiates your appetite
16:18:02 <itidus21> the second one is making you feel full

16:21:07 <itidus21> but if we take away all such bias factors

16:38:11 <atriq> It's called friendship?
16:38:46 <itidus21> uh.. i'm not sure. but something else. like i had been thinking about topics which come up here.
16:39:53 <atriq> Maybe you are actually #esoteric

17:42:11 <AnotherTest> What Haskell IDE do you people use (if any)?
17:51:00 <kmc> i just have vim and ghci open in two windows
17:51:35 <kmc> haskell is potentially a great language for very clever IDEs but i haven't seen a good one
17:51:45 <kmc> i used leksah for a little while but it was buggy
17:56:05 <AnotherTest> I might try leksah and hope it's not as buggy on my system
17:57:13 <AnotherTest> although I have the impression that most buggy software is buggy invariant of the system
17:58:48 <kmc> it depends
17:58:54 <kmc> inkscape is much worse on mac than on linux
17:59:13 <kmc> it's also possible that leksah got better in the intervening time
17:59:29 <AnotherTest> well it is taking a long time to collect information about Haskell packages on my system
17:59:37 <kmc> at the risk of unfounded generalization, i think haskell appeals more to the kinds of programmers who don't typically use IDEs
17:59:56 <kmc> and to some degree this blinds people to the advantages a haskell IDE could have, compared to IDEs for other languages
18:00:26 <AnotherTest> I actually don't, but I think a good IDE can definitely be useful (which is why I want one)
18:00:36 <kmc> i would love to use something like the emacs Agda mode for Haskell

19:33:31 <oerjan> 15:49:55: <atriq> :t (0 $ 0 `on`)
19:33:31 <oerjan> 15:49:56: <lambdabot> The operator `on' [infixl 0] of a section
19:33:56 <oerjan> anyone making an infixl 0 operator should be hanged and quartered.
19:34:07 <oerjan> (also infix 0, naturally.)
19:35:12 <oerjan> (this does not apply to _changing_ $ into infixl 0, in which case one would swap l and r.)
19:35:53 <olsner> the conditions under which one would be hanged and quartered are getting complicated
19:37:25 <oerjan> also there should have been another precedence above the default 9, which . should have had instead.
19:37:55 <olsner> maybe the precedences should be rationals
19:38:28 <oerjan> olsner: has been suggested, at which point someone will immediately suggest a system for general partial orders.
19:38:38 <olsner> I was just about to do that too
19:39:07 <oerjan> at which someone will point out that makes it awful to combine independent libraries. (at least that's what happened a week or so ago.)
19:39:55 <oerjan> my point, otoh, is that . and $ should be considered pseudosyntax and every fixity which conflicts with their natural use is wrong.
19:41:06 <oerjan> the above `on` being one, and parsec's <?> being the other example i recall.
19:43:09 <oerjan> basically someone should have developed some guidelines before user-defined operators started proliferating, and it's really too late now.
19:43:39 <oerjan> (the applicative operators mostly being 4 rather than the same as the corresponding monadic ones is another pet peeve of mine.)
19:45:04 <zzo38> I just think this is a problem with Haskell; fixity must be integer 0 to 9, and does not allow redefinition of fixity of things defined in another file.
19:45:15 <zzo38> (They could be fixed by an extension, I suppose.)
19:45:40 <oerjan> you can redefine functions in practice if you really want to, though.
19:46:04 <oerjan> on = Data.Function.on; infixr 0 `on`
19:46:17 <zzo38> Yes that is what I thought of too
19:46:35 <zzo38> Should fixities be surreal numbers?
19:47:09 <oerjan> rationals _should_ be enough for everyone, being able to represent all countable total orders
19:48:12 <oerjan> olsner: oh the last pointing out about partial orders was that if you define fixities by their relation to other operators, those other operators have to actually be imported...
19:49:00 <oerjan> which means you get unnecessary package dependencies
19:49:02 <zzo38> That is what I thought about using surreal numbers, by defining by relation to other operators
19:50:26 <oerjan> surreal numbers presumably allow any total order, regardness of cardinality.
19:53:41 -!- epicmonkey_ has quit (Ping timeout: 246 seconds).
19:54:35 <oerjan> the proof is sort of a generalization of the proof for rational numbers
19:55:29 <oerjan> for rational numbers, you need that between any non-interleaved finite set of rational numbers there is another one
19:55:43 <oerjan> for surreal numbers, the same is true without finiteness

19:56:05 <oerjan> *another rational number
19:56:08 -!- MoALTz has joined.
19:56:59 <oerjan> because the game with left and right options the smaller and larger set represents a surreal number between them.
19:59:06 <oerjan> you also need a well-ordering (not necessarily the same order) of the totally ordered set you want to embed
20:04:59 <oerjan> well, maybe not _strictly_ need one, you can get the real numbers embedded because they're separated by rationals, and i don't think this uses the real numbers being well-orderable.
20:06:03 -!- ogrom has quit (Quit: Left).
20:06:23 <oerjan> perhaps there's a clever argument which only uses the axiom of foundation instead...
20:07:07 <oerjan> but since there's no obvious guarantee that the total order respects set rank, i won't bet on it.

20:23:09 <shachaf> I suspect there's more than one attitude.
20:26:17 <oerjan> @tell Arc_Koen I think that your ocaml Brainfunct interpreter always treats @ with an undefined function (including 0, but not for >= 50) as using an empty function, is this intended behavior? (It's more useful than crashing anyway, as my haskell one does and as yours does for values >= 50)
20:26:43 <lambdabot> Arc_Koen: You have 1 new message. '/msg lambdabot @messages' to read it.
20:26:56 <oerjan> what about for values >= 50, ideally?
20:27:24 <Arc_Koen> ideally I guess the tape and the functions are unbounded
20:27:26 <oerjan> ok. i'll modify my haskell one.
20:27:41 <oerjan> my tape is already unbounded since it uses the zipper trick
20:28:12 <oerjan> (as well as haskell's infinite lists, but that just makes it slightly easier)
20:28:27 <Arc_Koen> I'm still trying to figure out why my interpreter ends on Stack_overflow on a tail-recursive loop
20:29:14 <oerjan> well your for loop comment seems correct to me, as it makes the '@' case not be in a tail position
20:29:35 <Arc_Koen> I mean, if the @ call is the last command in a function, the interpreter should reflect that
20:30:02 <Arc_Koen> I modified my program to have the last command out of the for loop
20:30:07 <kmc> shachaf: i've said it more than a few times
20:30:13 <oerjan> oh, you did not include that on the wiki
20:30:26 <Arc_Koen> well it did not work as intended so I did not edit
20:30:33 <kmc> i think C++ is a bad language, which is bad in almost the opposite way that languages are usually bad
20:30:36 <shachaf> akmc: It's basically a bad language, but it's interesting because it's bad in an opposite way to other languages?
20:30:57 <kmc> and despite being a bad language, it is sometimes the right tool
20:31:15 <Arc_Koen> the other modification I haven't put on the wiki page is | ',' -> tape.(!ptr) <- (try int_of_char (input_char stdin) with | End_of_file -> -1)
20:31:54 <Arc_Koen> but using that in the cat program would make it way more complicated
20:32:22 <kmc> it's also interesting just because it has lots of things that other languages don't
20:32:59 <Arc_Koen> (the simple, current version would try printing -1 as ascii so it would result in an error anyway)
20:33:28 <kmc> in my categorization of programming languages, C++ is practically the only language in its niche
20:36:13 <kmc> C++ has an elegance and internal consistency which is lost on most of its users
20:36:26 <kmc> because they mostly program in a hodge-podge of C and C++
20:36:44 <kmc> the reason they do that is that C++'s internal consistency isn't so much externally consistent with the real world
20:37:17 <kmc> also it's just very fun to write C++ in small doses and try to do excessively clever things
20:37:26 <kmc> which is one reason i call it an esolang
20:37:33 <shachaf> That's true about most languages, isn't it?
20:37:34 <kmc> and now you know
20:37:40 <kmc> how i feel about C++
20:37:48 <kmc> i hope you will use this knowledge for good and not evil
20:38:01 <shachaf> kmc: Did I ever ask you again about the stream-cipher-for-disk-encryption thing?
20:38:24 <kmc> shachaf: well, some languages try to limit the amount of cleverness you can use
20:38:39 <kmc> and others are just a mess such that clever things never really seem elegant
20:39:06 <kmc> C++ and Haskell are very similar in my mind
20:39:16 <kmc> ignoring the technical details of each language, and focusing on these kinds of factors
20:39:31 <kmc> now there's a statement which is bound to upset almost everyone ;)
20:39:47 <kmc> but i promise i'm not trolling, i really do think C++ and Haskell are very similar on this level
20:40:48 <kmc> why did you go to los angeles

21:21:41 <oerjan> Arc_Koen: er your - is wrong :)
21:22:05 <Arc_Koen> I think that's the most stupidest error i've ever had in a program
21:22:19 <oerjan> the only command none of your previous programs tested, i think :P
21:23:34 <oerjan> Arc_Koen: hey don't worry, i almost managed to get + and - include an automatic > because i put the new value in the wrong zipper list
21:23:52 <oerjan> because i had simply copied and pasted the code for > to modify
21:24:40 <oerjan> does the new cat work now?
21:26:32 <Arc_Koen> one sec - the invalid argument thing simply came from the program trying to read exactly one more command than there were characters in the current function
21:26:46 <oerjan> Arc_Koen: your code looks tail recursive to me
21:27:12 <Arc_Koen> there was a stupid -1 / +1 error in the loop
21:27:45 <Arc_Koen> (so the for loop still did everything, and the step after the loop tried to read an imaginary command
21:28:26 <oerjan> itidus21: i don't think any of our interpreters use 8-bit cells
21:28:47 <oerjan> mine uses Int, although it would be a simple substitution to use unbounded Integer
21:28:48 <Arc_Koen> urrh, still an error somewhere
21:32:40 * oerjan convinces himself that runs the right commands in a function
21:33:23 <Arc_Koen> | x -> raise (Unknown_command x) is kind of ridiculous since all brainfuck specifications seem to agree that unknown characters are no-ops that can be used for comments
21:34:05 <oerjan> i allowed whitespace but nothing else
21:34:46 <Arc_Koen> I just added that line without further thinking when the compiler told me "warning: non-exhaustive pattern matching"
21:40:18 <oerjan> i don't see anything obviously wrong with your last paste
21:43:29 <Arc_Koen> well I'll add a lot of print_string to see where the index out of bounds come from
21:44:39 <Arc_Koen> oh and I found http://esolangs.org/wiki/BrainCursion should I add a "see also" link or something?
21:45:41 <itidus21> its about this point where i remember that #esoteric is actually discussing brainfuck and thus most rational comments do not apply
21:46:11 <oerjan> Arc_Koen: i don't think they're that similar
21:46:24 <itidus21> because, brainfuck programmers are a mythical entity
21:46:28 <oerjan> beyond both being brainfuck derivatives
21:46:37 <Arc_Koen> itidus: a friend showed me a link to someone who has implemented brainfuck in SpaceChem... now *that* is mythical
21:47:06 <itidus21> well.. the uh.. consumer of brainfuck interpreters is the mythical part :P
21:47:21 <Arc_Koen> oerjan: well my motivation for making brainfunct was "wait is it so that among all the brainfuck derivatives, the obvious functional version is missing?"
21:47:55 <Arc_Koen> and braincursion seems to be claiming more or less the same thing, even though I haven't really understood what was its point :p
21:48:30 <oerjan> Arc_Koen: not really, it can only jump to the matching ( or ) i think
21:48:31 <itidus21> i guess what i am saying is not quite true considering that people make interpreters in brainfuck
21:48:39 <itidus21> its a great interpreter writing language
21:50:37 <itidus21> i got x and y axis confused on esointerpreters
21:51:20 <oerjan> hm it doesn't even do matching, if the interpreter is to be believed
21:51:26 <Arc_Koen> hmmmmmm does braincursion support nested loops correctly?
21:53:03 <itidus21> basically i think all the brainfuck programs that are going to be written have been written
21:53:28 <itidus21> so, the hypothetical end user of a brainfuck interpreter is just a useful uhhh
21:53:32 <oerjan> however this directly contradicts the computational class section of the article
21:54:29 <Arc_Koen> well that sections links to "reduction", in which it is said "be careful with the arbitrary thing at the arbitrary moment!!!" which is not respected by the loop emulation in braincursion
21:54:54 <oerjan> @tell spirity Did you mean for loops in BrainCursion to nest properly? The interpreter doesn't.
21:55:29 <Arc_Koen> oerjan: according to the description of the language it doesn't either
21:55:39 <Arc_Koen> (at least not in such an easy way)
21:56:00 <oerjan> @tell spirity The description seems to imply they shouldn't, while the computational class section makes no sense if they don't.
21:57:40 <oerjan> no, spirity and Seven Inch Bread is
21:58:14 <oerjan> the computational class comment is older than the interpreter, at least
21:58:57 <oerjan> in fact it's by the original article author. which is an IP, so may or may not be the same as the language author, but most likely is.
21:59:25 <oerjan> btw i hesitate to call the loops described "recursive".
21:59:52 <Arc_Koen> yup that's what I did not really understand
22:00:21 <oerjan> so no matter how you slice it, it's not very similar to Brainfunct.
22:00:41 <Arc_Koen> anyway, "recursive" wouldn't mean much if it's still and explicit loop
22:01:39 <Arc_Koen> I remember when I had programming exercises to do at the university and it was explicitly said "this algorithm must be written in an imperative way" I often "cheated" by emulating recursion using a stack
22:05:08 <oerjan> Arc_Koen: btw as a conoisseur of TC proofs, i find the phrase "arbitrary effect at an arbitrary point" and even the entire Reduction section _far_ too imprecise (and don't actually describe the technical meaning of reduction.)
22:06:14 <oerjan> *connoisseur dammit :P
22:06:39 <Arc_Koen> it took me a while to understand what they meant with "arbitrary effect at an arbitrary point", and what's said about reduction basically is "reduction is a good way to prove a language TC except sometimes it's not a proof at all"
22:07:09 <oerjan> real reduction is definitely a proof, but you have to apply to an entire program (sometimes including the I/O)
22:07:17 <Arc_Koen> (the french word actually is "connaisseur" with an a :p)
22:07:53 <oerjan> "A connoisseur (French traditional (pre-1835) spelling of connaisseur"
22:08:03 <oerjan> so it's not wrong to use it in english, by tradition
22:08:28 <Arc_Koen> I know but it does sound weird when the reader is french :p
22:10:10 <Arc_Koen> (well, I didn't know where the o came from. I thought it was just an original misspelling.)
22:12:14 <Arc_Koen> (or something similar to "rendezvous" being written as a single word)
22:12:34 <oerjan> well sometimes you can reduce each instruction separately, when the language's have essentially identical semantics for how sequences of instructions are combined.

23:38:10 <kmc> is any modern C compiler going to object to non-ASCII UTF-8-encoded characters in a multiline comment?
23:38:37 <kmc> i figure, even if it decodes them as 8-bit characters, it will be fine because they will not match "*/" as encoded in the ISO 646 invariant set
23:38:46 <zzo38> Since it won't contain the ASCII */ then probably it will work OK.
23:39:14 <zzo38> (If you need to actually use the */ in the comment then use the overlong encodings)
23:40:23 <zzo38> Overlong encodings are not really valid UTF-8 but use it anyways if you need to.
23:41:50 <FreeFull> They're alternate encodings for the charaters U+00 to U+7F
23:42:54 <kmc> you prepend some bytes which encode zeros
23:43:32 <pikhq> kmc: It should "just work" regardless.
23:43:33 <kmc> http://blogs.msdn.com/b/michael_howard/archive/2008/08/22/overlong-utf-8-escapes-bite.aspx
23:44:45 <pikhq> kmc: The beauty of UTF-8 is that you'll never get valid ASCII out of it except when it's the chunk mapping to ASCII... So you'd have to really work to break on UTF-8 there.
23:44:47 <zzo38> If you are using UTF-8, another thing you could do if you want */ in a C comment is to put a zero-width space between.
23:45:05 <kmc> do zero-width spaces work in fixed-with fonts?
23:45:11 <kmc> are they like a no-op combining character?
23:45:26 <oerjan> they work in irssi anyway
23:45:49 <zzo38> They are supposed to have zero width; in PuTTY on my computer it displays a replacement box even though it does not advance the cursor.
23:46:43 <zzo38> So in that example, it appears on my computer the zero-width space replacement box overlapping the colon.
23:47:18 <zzo38> (And for some reason it is gray rather than blue; this may be a bug in PuTTY)
23:47:44 <FreeFull> Maybe your font still needs to have the empty character set for the zero-width space to work correctly
23:47:48 <zzo38> FreeFull: The colon before the IRC message. (The syntax of IRC require a colon to indicate long parameter that may contain spaces)
23:48:06 <FreeFull> zzo38: What, you don't use an IRC client?
23:48:22 <zzo38> FreeFull: I do use an IRC client. But probably not the same one you used.
23:48:47 <pikhq> Isn't your IRC client more a syntax-highlighting IRC protocol displayer?
23:49:17 <FreeFull> I mostly use irssi, because the irc client I wrote myself isn't that good =P
23:49:40 <kmc> i think someone should package GNU/Linux, Mosh, screen, and irssi as an EC2 AMI
23:49:49 <kmc> to make it super easy to set up persistent IRC in The Cloud
23:50:02 <kmc> there is also https://irccloud.com/ but i heard it is slow
23:50:03 <pikhq> I'd be tempted to, except I just got my Internet stable.
23:50:11 <zzo38> pikhq: Yes mostly those are what it does; although it has other features too.
