00:14:40 <oerjan> @ask Phantom_Hoover wtf happens here http://www.sheldoncomics.com/archive/130904.html
00:14:40 <lambdabot> Consider it noted.

00:19:11 <HackEgo> Phantom Michael Hoover is a true Scotsman and hatheist.
00:19:21 <oerjan> it says _true_ Scotsman, Phantom_Hoover
00:19:37 <kmc> so glad that the nvidia binary OpenGL drivers for Linux make heavy use of self modifying code
00:19:51 <Phantom_Hoover> oh dear, this is getting intractible
00:21:11 <Fiora> kmc: ouch
00:21:19 <Fiora> what do they use it for?
00:21:20 <kmc> @tell Koen_ I think && and || are just special cased in the language, as in most languages
00:21:21 <lambdabot> Consider it noted.
00:21:25 <kmc> Fiora: I don't even know...

00:23:02 <Fiora> um, if I might ask where did this come up o_O
00:23:21 <kmc> the self modifying code?
00:23:34 <kmc> trying to figure out why my program is crashing in the opengl library
00:23:42 <Fiora> ohhhh
00:23:56 <kmc> (the answer turns out to be, calling OpenGL functions from a thread other than the one which set up OpenGL, which is a pretty normal answer really)

01:56:12 <madbr> I'm starting to think that out of order execution is just a really elaborate prefetch scheme
02:25:46 -!- Poolala has joined.
02:29:44 -!- carado has quit (Ping timeout: 246 seconds).
02:33:47 <madbr> like, is there any point to out of order execution, other than dealing with unoptimized code and trying to hide cache misses?
02:36:08 <madbr> (and having too few registers on x86)
02:42:21 <madbr> in other words
02:42:42 <madbr> if you had an optimal architecture and no cache misses, would out-of-order be useless?
02:45:08 <Bike> are those reasonable assumptions, though
02:46:07 <madbr> well, for optimal architecture IMHO even the stupid traditional 32 register MIPS would fit
02:46:33 <madbr> like, it probably can't do 10 instructions per cycle, but no architecture can do that
02:47:57 <Bike> i mean, no cache misses/"unoptimized code"
02:48:26 <madbr> no cache misses obviously isn't very "real world" :3
02:48:33 <Bike> right
02:49:00 <madbr> unoptimized code I'm not too sure about
02:49:03 <Bike> and i mean isn't there a longstanding debate or whatever about whether compilers should be expected to make good code versus the processor working things out
02:49:20 <madbr> well
02:49:37 <madbr> I expect most compilers nowaday turn everything into SSA form
02:49:51 <Bike> heh, heh.
02:50:04 <madbr> and can do at least a minimum amount of reordering
02:50:47 <madbr> and by "most compliers" I really mean msvc, llvm and gcc
02:51:46 <madbr> I don't expect compilers to be able to do enough reordering to keep a 10-issue cpu busy
02:51:55 <madbr> but a 2 or 3 issue cpu sounds reasonable
02:52:17 -!- carado has joined.
02:55:29 <madbr> like, multiplications are high latency so they require a lot of shuffling, but usually they happen in stuff like dsp and gfx code that's usually math heavy anyways
02:57:46 <madbr> load/store/jump code is mostly low latency ops, though it has less math ops that you can shuffle around... then again if it has unavoidable dependency chains, it's going to have unavoidable dependency chains on a pentium 2 too
02:58:35 <madbr> stuff like file compression and string parsing

03:55:14 <Sgeo> I have an utterly crazy idea of how to implement it
04:03:48 <Sgeo> Well, ok, not C++ templates crazy
04:08:10 <Sgeo> Deadfish... is not very well specified, is it. The page implies that something is a vagriety of the C implementation, then says to check against its math results to see that that thing is there
04:08:27 <Bike> it is a joke
04:15:39 <oerjan> Sgeo: the joke is that we follow the C implementation faithfully especially in those aspects which show its author was not very good at programming.
04:16:04 <Sgeo> Oh
04:16:11 <Sgeo> Maybe I should look at the C impl. then

04:24:22 -!- carado has joined.
04:24:39 <Bike> i'm impressed at the apl implementation, but i feel it could probably be optimized
04:24:51 <Sgeo> Um. Except I'd try to avoid recursive loops in non-TCOed languages
04:26:27 <Sgeo> err, that -1 check is useless, isn't it.
04:26:43 <Bike> "unsigned int x; /* make a positive integer and call it x */" man, this is some good stuff.
04:26:44 <oerjan> no?

04:26:59 <oerjan> oh hm
04:27:00 <shachaf> Bike........
04:27:11 <shachaf> why are you doing the thing where you insult people
04:27:25 <Sgeo> It's an unsigned int, does C convert the -1 to MAXINT or whatever -1 underflows into?

04:27:48 <Bike> congenial condition also
04:28:07 <Bike> wow good scanf.
04:28:51 <oerjan> Sgeo: well decrementing 0 gives 0, is what we've used. i assume we tried it out by running the C implementation at some point.
04:29:17 <shachaf> help
04:29:18 <Sgeo> erk http://ideone.com/uQDIhD
04:29:19 <shachaf> what's this code
04:29:49 <oerjan> the exact bitsize isn't among the things we keep slavishly to. (some of my esolang implementations use unary.)
04:30:49 <Sgeo> Why doesn't it die? Does scanf not stop and wait for input?
04:31:11 <Sgeo> Or, maybe IdeOne is just broken
04:33:11 <oerjan> Sgeo: don't you give all input up front in IdeOne?
04:33:27 <oerjan> in any case, yes the interpreter has no eof checking.
04:33:37 -!- carado has quit (Ping timeout: 246 seconds).
04:33:54 <oerjan> oh wait, it shouldn't print the 0 ...
04:34:22 <Sgeo> All I wanted to do was compile i d s and o into ;i; ;d; ;s; ;o; and eval it
04:34:24 <Sgeo> >.>
04:34:45 <oerjan> well, my screen is full of &gt; stuff which does not look promising.
04:35:21 <Sgeo> oerjan: on IdeOne? Or actually compiling locally?
04:35:37 <oerjan> on IdeOne.
04:35:54 <shachaf> more like IdeoNe
04:37:30 <oerjan> Sgeo: locally on nvg it keeps prompting after any number of ^D (for eof)

04:48:01 <Sgeo> o.O ?
04:48:45 <oerjan> my downloaded version has scanf("%c%*[^\n]%*1[\n]",&usrinput);
04:48:49 <oerjan> whatever that does.
04:50:23 <oerjan> probably some attempt at reading only one command per line, i guess. (and it doesn't work :P)

06:37:22 <shachaf> ion: You know the whole (s,) -| (s ->) adjunction business and the way you get State from that?
06:38:01 <ion> shachaf: No. I’m not familiar with the -| symbol either, or with the word adjunction for that matter. :-P
06:38:21 <ion> (in this context)
06:39:00 <shachaf> Well, in Haskell in particular, an adjunction is a relationship between two functors F and G, written F -| G, such that (F a -> b) ~~ (a -> G b)
06:39:59 <Sgeo> Are there any non-boring monads that meet the criterion I mentioned?
06:40:19 <Sgeo> Of bind only being able to use the callback it's given at most once?
06:41:00 <shachaf> ion: It has lots of good properties, including that G . F is a monad and F . G is a comonad.
06:43:49 <ion> shachaf: I see.
06:44:33 <shachaf> ion: It comes with two operations, eta :: a -> G (F a) and eps :: F (G a) -> a
06:44:35 <ion> Can you give an example of an adjunction other than (s,) -| (s ->)?
06:44:52 <shachaf> With the laws fmap eps . eta = id, and eps . fmap eta = id
06:45:19 <shachaf> ion: Unfortunately it's hard in Haskell. :-(
06:45:39 <shachaf> Most interesting adjunctions involve functors that aren't endofunctors.
06:46:17 <ion> Could you give an example of one of those?
06:47:13 <shachaf> Well, do you know abou the category Mon of monoids/monoid homomorphisms?
06:48:23 <shachaf> (Do you know about categories and functors in general?)
06:49:15 <ion> Nope. I have Awodey’s book in my reading queue.
06:49:27 <ion> and Spivak’s
06:49:50 <shachaf> Spivak?
06:50:03 <shachaf> Oh, _Category Theory for Scientists_?
06:50:33 <ion> Yeah.
06:51:07 <shachaf> Hm. I don't know much about it.
06:51:23 <shachaf> Anyway, categories are so easy.
06:52:21 <ion> I’m sure i’ll love them.
06:53:02 <shachaf> Well, you know Category in Haskell, right? It's just that.
06:53:31 <ion> yeah
06:54:55 <shachaf> And do you know what a functor is between categories?
06:57:27 <ion> No. It’s not immediately obvious to me how to make that happen with the functor familiar to me (which is, i guess, really an endofunctor).
06:58:31 <shachaf> OK, so a category is a thing with a bunch of arrows, which can be composed.
06:59:07 <shachaf> To figure out which arrows can be composed, you have the objects. You can only compose two arrows if their objects match.
06:59:29 <shachaf> (So each arrow has a "type".)
06:59:42 <shachaf> And there are also identity arrows, one for each object.
07:00:40 <shachaf> A functor F from C to D maps each arrow "a" in C to an arrow "F a" in D, such that F id = id, and F f . F g = F (f . g)
07:00:46 <shachaf> Normally we write F as fmap in Haskell.
07:01:45 <shachaf> It also maps objects, but once you've specified how you're mapping the arrows, you can figure out the object mapping from that.
07:01:52 <ion> hmm, ok
07:02:01 <shachaf> Hmm, I'm being confusing, maybe because it's midnight?
07:02:20 <shachaf> Do you see how this corresponds to the regular Haskell Functor?
07:02:44 <ion> Does the “endo” mean that C = D?
07:02:47 <shachaf> Yep.
07:03:20 <shachaf> It maps Haskell arrows to Haskell arrows -- e.g. ord :: Char -> Int to fmap ord :: F Char -> F Int -- with the laws I mentioned above.
07:03:42 <ion> I guess i see it. What’s an example of C,D where C ≠ D?
07:03:44 <shachaf> It also maps objects to objects, e.g. the type Char to the type F Char.
07:03:59 <shachaf> Maybe we should've had a bunch more examples of categories first.
07:05:23 <shachaf> Maybe I'm spamming the channel...
07:05:51 <ion> It doesn’t seem like there’s other discussion going on at the moment.
07:06:06 <shachaf> Maybe that's because of me!
07:06:12 <ion> heh
07:06:18 <shachaf> OK, so let's go back to categories and give some examples.
07:06:43 <shachaf> And maybe a proper definition? Did we ever have one?
07:08:17 <ion> I don’t think so, apart from “like Data.Category.Category”
07:08:50 <shachaf> Hmm, I think I meant Control.Category, although data-category's definition is generally much better.
07:09:49 <shachaf> OK, let's start with something else. You know what a monoid is, right? A collection of things, which can be "multiplied" with each other, such that multiplication is associative and has an identity?
07:10:16 <ion> Sorry, i meant Control.Category.Category
07:10:30 <ion> yeah
07:10:55 <shachaf> E.g. ℕ with + and 0, ℕ with * and 1, String with (++) and "", and so on.
07:11:05 <shachaf> OK, so you know how matrices work, too, right?
07:11:31 <shachaf> (Or maybe not. I certainly don't.)
07:12:03 * shachaf is falling asleep.
07:12:11 <shachaf> `? sleep
07:12:14 <ion> More or less. I always have to look up things like how to calculate a determinant etc.
07:12:16 <HackEgo> Sleep is for the weak.
07:12:27 <shachaf> thanks for the reminder, HackEgo
07:12:31 <shachaf> But e.g. matrix multiplication?
07:12:36 <ion> yeah
07:13:00 <shachaf> Matrices and matrix multiplication are funny because they're almost like a monoid but not quite.
07:13:17 <shachaf> Because you can't multiply any two matrices, you can only do it if they match.
07:13:42 <ion> yeah
07:13:53 <shachaf> So you have (*) :: M i j -> M j k -> M i k, and you have id :: M i i for any i.
07:14:21 <fizzie> shachaf: I see you haven't been keeping up with the news: https://collectivelyunconscious.wordpress.com/2013/07/28/matrix-dimensions-reach-agreement-at-peace-summit/
07:14:51 <shachaf> So that's how categories work in general. You have a multiplication operation but it only works for things that match.
07:15:07 <shachaf> fizzie: Oh no!
07:15:11 <ion> Ok, matrices are a nice example.
07:15:35 <shachaf> So, for a category C, you have, uh...
07:15:57 <shachaf> A collection of objects
07:16:53 <shachaf> A collection of arrows, where each arrow is has a domain and codomain (source and taget) object, written as e.g. f : A -> B
07:17:50 <shachaf> A composition operation, (.), which can compose two matching arrows. I.e. for any two arrows f : A -> B, g : B -> C, you can write g . f : A -> C
07:18:48 <shachaf> For every object A, you have an identity arrow, id : A -> A, such that f . id = f, id . f = f
07:19:00 <shachaf> (Sometimes you specify which object you're talking about by writing e.g. id_A)
07:19:12 <shachaf> And composition is associative, so (f . g) . h = f . (g . h)
07:19:19 <shachaf> Does all that make sense?
07:21:17 <shachaf> @yarr
07:21:17 <lambdabot> Splice the Mainbrace!
07:21:22 <shachaf> @arr
07:21:22 <lambdabot> Arrr!
07:28:53 <ion> shachaf: I was thinking about whether matrix transposition would be a valid functor from M i j to M j i, but that would violate the F f . F g = F (f . g) rule. (The rule for this would be F f . F g = F (g . f), i think.)
07:29:10 <ion> shachaf: Yeah, makes sense.
07:30:29 <shachaf> OK, that kind of functor exists too, and it even turns out to be the same kind of functor.
07:31:06 <shachaf> Anyway, we should have some examples.
07:31:50 <shachaf> So there's the matrix example.
07:32:03 <shachaf> Also, a monoid is the same thing as a category with one object. Do you see why?
07:33:57 <ion> The single object is the type of the monoid?
07:34:35 <ion> (*) :: a -> a -> a always
07:34:47 <shachaf> Right.
07:34:55 <shachaf> Well, not "the type of the monoid"
07:35:02 <shachaf> The object can be anything.
07:35:40 <shachaf> Each arrow corresponds to an element of the monoid. The object is just there so the arrows can have a domain/codomain.
07:35:44 <ion> Yeah… Still stuck in the familiar thinking. :-)
07:36:26 <shachaf> Another popular simple example is a partially-ordered set. You know those?
07:41:27 <ion> Reading the Wikipedia page… Something with (≤) :: a -> a -> Maybe Bool?
07:41:54 <shachaf> Well, a relation, but you can think of it that way.
07:41:55 -!- carado has quit (Ping timeout: 246 seconds).
07:42:37 <shachaf> A poset is a set along with a relation ≤, with the three properties listed in that page you're probably reading right now.
07:47:22 <ion> Ok, i guess i get it. The set of subsets ordered by inclusion is a good example.
07:48:04 <shachaf> Right.
07:48:56 <ion> Natural numbers ordered by divisibility, too.
07:49:26 <shachaf> So you can look at any poset as a category, where the objects are the elements of the set, and you have an arrow from A to B iff A ≤ B
07:49:39 <shachaf> Otherwise you have no arrows.
07:49:50 <shachaf> Note that you have at most one arrow between any two objects this way.
07:51:23 <ion> I take it the identity arrow corresponds to reflexivity and composition corresponds to transitivity?
07:51:36 <shachaf> Yep.
07:52:02 <ion> Ok, i guess i get it.
07:52:37 <shachaf> (There's no category axiom that corresponds to antisymmetry, because it's still a category even without that.)
07:53:04 <shachaf> (I guess you could say that a poset is skeletal or something? Doesn't matter.)
07:53:18 <shachaf> OK.
07:53:30 <shachaf> So another category is one where the arrows are functions and the objects are sets.
07:53:34 <shachaf> Or Haskell types, for that matter.
07:54:00 <shachaf> (We usually pretend that Haskell is total when we say that, to make life easy.)
07:55:12 <shachaf> And then you have lots of other categories for lots of other things you might want to talk about.
07:55:34 <shachaf> E.g. you have a category where the objects are monoids and the arrows are monoid homomorphisms.
07:55:41 -!- madbr has quit (Quit: Radiateur).
07:55:55 <shachaf> (A monoid homomorphism is a function f between monoids where f(1) = 1 and f(a)*f(b) = f(a*b).)
07:55:59 <shachaf> (That might look familiar!)
07:58:32 * ion makes notes
07:59:34 <shachaf> There are also very small categories, like the category 0 with no objects and no arrows, the category 1 with one object and one arrow, and various other ones.
08:01:07 <shachaf> Oh, for any category, there's its "opposite category".
08:01:17 <shachaf> Which is pretty much the same thing except the arrows are backwards.
08:01:55 <shachaf> So in the category Hask^op, an arrow from A to B is a Haskell function from B to A.
08:03:37 <shachaf> Does the definition of functor make sense with all of these?
08:03:53 <shachaf> What would a functor between two posets be?
08:05:16 -!- epicmonkey has joined.
08:09:17 <shachaf> (There are also a bunch of boring ways to make categories, like a category where the only arrows that exist are identity arrows, but who cares about those.)
08:10:21 <shachaf> OK, I'm going to sleep.
08:10:58 <ion> I just finished writing notes about everything up to now. Good night, and thanks a lot. I’ll think about the question about a functor between two posets.
08:11:44 <shachaf> Oh, if you're here you can probably figure it out.
08:12:19 <shachaf> Just give the definition of a functor, and replace "an arrow from A to B" with "we know that A ≤ B".
08:12:39 <shachaf> (You don't care *which* arrow because there's at most one.)
08:14:06 <shachaf> Anyway, sleep.
08:14:49 <ion> I’m a bit too tired to concentrate as well, i’ll watch a TV show episode or two with a friend and get some sleep. I’ll continue from this point at a later time.

12:33:52 <fizzie> I also had both right ones done before the summer.
12:36:29 <boily> weird pattern, but it sounds more pragmatic than "top two" then "bottom two".
12:36:49 <boily> the top procedure is like just about anything else. a little hurt, but nothing more.
12:36:58 <boily> but the bottom two... ooooooh... *shudders*
12:37:47 <fizzie> The idea was that I'd still have one side of the mouth to chew with.
12:38:09 <fizzie> Except the other side's so swollen I'd just be biting my cheek the whole time. But I guess it'll subside.

14:09:17 <itsy> Hi Mnoqy :-)
14:09:20 <mnoqy> hi

14:10:09 <Roujo> Also, hi mnoqy
14:10:19 <mnoqy> yes the joke is that thinking about irc like that is horribly wrong but solain seems to do it anyway

14:11:31 <Roujo> *waits 30 seconds*
14:11:35 <Roujo> *quits*
14:14:04 <boily> or, "hey, I have this problem" *32 seconds* "solved it myself. kthxbye!"
14:16:37 <fizzie> Sometimes there's an insult before the quit.

16:04:02 <Rafajafar> hi guys, I remember meeting some brilliant folks in here once. Maybe you can help. I have a very specific problem and am looking for a solution that might already exist
16:04:16 <Rafajafar> I'm searching for a solution that can do sliding-window searches on collections of ordered data. Think if you've got fingerprints for each frame of a movie: f(1), f(2)... f(n) and you intercepted a subclip from that movie and have it's finger prints s(1), s(2)...s(n)
16:04:32 <Rafajafar> now I could do this in any language, really, but I need something that will index and do a fuzzy search
16:04:46 -!- k_k_k has joined.
16:04:53 <Rafajafar> ou needed a specific comparison function to compare one fingerprint to another
16:05:17 <Rafajafar> and that function is essentially a euclidean distance function with a tolerance threshold
16:05:42 <Rafajafar> do you guys know of any language that would be primo for that, OR, do you know of an esoteric data storage system for such a sliding-window database

16:20:36 <ais523> elliott: you forgot to stealth your ops
16:20:50 <ais523> also, I've been creating an esolang :)
16:20:59 <ais523> it's probably my second-best esolang ever, after Underload
16:21:04 <ais523> err, that exists, I mean

16:21:33 -!- elliott has set channel mode: -o elliott.
16:21:47 <ais523> elliott: it's easy to forget, I've been yelled at in other channels for that :)
16:22:29 <ais523> sadly, I don't have an impl or any programs yet; I was considering holding off on releasing it until I had some
16:23:06 <elliott> what's it like?
16:23:23 <ais523> "Snowflake is a reversible, self-modifying, data-parallel esoteric programming language created by User:ais523 in 2013."
16:23:27 <ais523> first line of the wiki article I'm writing atm
16:23:41 <ais523> also the "self-modifying" is more literal than normal
16:23:46 -!- Rafajafar has left.
16:23:51 <ais523> executing Snowflake programs actually alters the interpreter
16:24:44 <ais523> (this also makes it impossible to compile; if you had a compiler, you could compile a program, then delete the compiler, then executing the program would leave you with no implementation to modify)
16:25:01 <elliott> I'm glad you're still insane.
16:25:25 -!- conehead has quit (Ping timeout: 245 seconds).
16:25:35 <ais523> :)
16:26:15 <ais523> at one point during its development, a hello world program would likely need strong AI
16:26:18 <ais523> but I toned it down a bit
16:26:52 <ais523> completely independent of all the self-modification stuff, it also has a fun set of primitives
16:26:55 -!- zt has joined.
16:27:13 <ais523> it's stack-based, but doesn't really have any of the usual primitives
16:27:19 <ais523> it almost has () from Underload, except sometimes not
16:27:25 <ais523> also it has rotate
16:27:34 <ais523> but that's about it if you wanted something sane
16:27:51 <ais523> oh, it also almost has cons
16:28:41 -!- zt has quit (Client Quit).
16:30:25 -!- nooodl has joined.
16:32:22 <ais523> incidentally, I also had another language idea
16:32:48 <ais523> basically, it looks for the eight most commonly occurring repeated patterns in the source, and does some statistical analysis
16:32:58 <ais523> then interprets them as BF instructions and execute
16:33:13 <ais523> it'd save everyone time if we had an interp for all these pointless BF derivatives preëmptively
16:33:36 <mnoqy> good idea
16:34:30 <Roujo> ais523: Why did people yell at you because you had your op-hat on?
16:34:35 <ais523> actually, you could get like 99% accuracy just by printing "Hello world" if the program couldn't be recognised
16:34:47 <ais523> Roujo: it's not so much yelling, it's more just reminding people to take it off again
16:34:56 <ais523> you don't want everything you say to be perceived as official
16:35:05 <ais523> it's like trying to play Agora entirely on a-b, but worse
16:35:10 <Roujo> Ah, right
16:35:54 <Roujo> Levels the talking field, true
16:36:34 <ais523> the other thing is that people joining a channel with visible ops typically assume that there's a troll attack going on /right now/
16:36:36 <Roujo> I'm used to talking in channels where everyone is +o, so I didn't get why =P
16:36:40 <Roujo> Heh
16:37:14 <ais523> that's unlikely to happen here; elliott has little tolerance for known troublemakers, and unknown troublemakers are normally much too fun to toy with to actually use op powers on them
16:37:33 <Roujo> ^^
16:38:14 <ais523> also, re the topic: "peöple"?
16:38:22 <ais523> I can pronounce that but it doesn't seem to be a real word
16:38:52 <ais523> also, is there any particular reason why LaTeX?
16:39:01 <ais523> (or at least, LaTeX styling and fonts)
16:41:05 <ais523> oh right, someone's just added a bunch of diaereses even where they don't apply :(
16:41:42 <ais523> also I dislike the way backquote is rendered
16:42:20 <ais523> who should I send these comments to, anyway? I instantly assumed Gregor was responsible, but browsing through the reasons behind this, I can't think of any reason why he would be
16:42:30 <ais523> (also the fact that it's on dropbox not codu implies it's likely someone else)
16:43:01 <fizzie> ais523: The wisdom PDF is boily's work, unless I misremember.

16:44:40 <fizzie> The backtick is very confusing, yes, I think someone already complained about it?
16:44:55 <shachaf> hi ais523
16:45:02 <ais523> hi
16:45:52 <ais523> also, I'm disappointed that nobody's talking about Snowflake :(
16:46:40 <elliott> you didn't tell us you finished the article!
16:46:50 <ais523> oh right
16:46:52 <elliott> oh god, it's huge again.
16:47:00 <ais523> it's a complex language
16:47:05 <ais523> thus why I don't have an interp yet
16:47:18 <ais523> btw, if you write a Snowflake interp, I strongly recommend keeping a backup

16:47:52 <elliott> ais523: polarised nested lists is an oklopolism, by the way
16:48:00 <ais523> elliott: good to hear it
16:48:13 <elliott> he had a beautiful language based around them that I forget the details of
16:48:23 <ais523> it probably wasn't Snowflake
16:48:29 <ais523> but it's a natural way to do reversibility
16:48:45 <ais523> because you can use a polarity flip to easily handle error conditions in a reversible way
16:49:05 <Roujo> `complain The backtick doesn't render right
16:49:06 <HackEgo> Complaint filed. Thank you.
16:49:24 <elliott> it was nop-based, I think
16:49:35 <elliott> I think it used the syntax <...> for positive lists and >...< for negative ones
16:49:39 <elliott> using whitespace to disambiguate
16:49:42 <ais523> oh no, this PDF has the QDB appended

16:53:29 <Roujo> <ais523> also, is there any particular reason why LaTeX?
16:53:39 <Roujo> Probably because boily really likes LaTeX
16:53:42 <ais523> I guess
16:53:48 <ais523> LaTeX makes pretty much everything look academic

16:58:09 <ais523> (echo adds space between its arguments, and the output's going to /dev/null anyway)
16:58:49 <shachaf> ais523: I feel the need to use correct idioms by default when possible.
16:58:53 <ais523> I guess a habit that quotes arguments correctly is a good habit to have
16:59:01 <shachaf> Rather than think "should I use quotes here or " -- yes, that.
16:59:06 <Roujo> `run cat bin/complain
16:59:08 <HackEgo> echo "$@" >> /dev/null; echo Complaint filed. Thank you.;
16:59:10 <shachaf> Except $@ is very special and gets quoted in a special way.
16:59:11 <Roujo> Nice
16:59:13 <shachaf> But oh well.
16:59:38 <ais523> well $@'s entire purpose is to get quoted correctly
16:59:44 -!- FreeFull has joined.
16:59:54 <Roujo> `run sed -i 's/>>/>/g' bin/complain
16:59:58 <HackEgo> No output.
17:00:02 <Roujo> `run cat bin/complain
17:00:03 <HackEgo> echo "$@" > /dev/null; echo Complaint filed. Thank you.;
17:00:03 <shachaf> $@ is weird because «"$@"» gets split into multiple arguments.
17:00:11 <Roujo> There, that's even better
17:00:24 <shachaf> `complain ais523 doesn't visit us enough
17:00:25 <HackEgo> Complaint filed. Thank you.
17:00:48 <ais523> shachaf: well, I spent days of thought + an evening writing a new, complex esolang which is some of my best work
17:00:54 <ais523> and #esoteric continues not discussing esolangs
17:01:04 <ais523> at this point I'm not sure it's possible to get ontopic discussion here
17:01:11 <ais523> and although I don't mind offtopic discussion
17:01:16 <ais523> the ontopic discussion is the reason I come here
17:01:24 <Gregor> Womp womp
17:01:27 <ais523> if there's no reason for me to be here, I don't visit
17:01:51 -!- Vorpal has joined.
17:02:08 <ais523> Vorpal: http://esolangs.org/wiki/Snowflake
17:04:12 <Gregor> Hey, that's the name of my Linux distro X-D
17:04:26 <ais523> no reason I can't name an esolang after a Linux distro :)
17:04:31 <ais523> (although it wasn't, we can pretend if you like)
17:06:24 <Gregor> “due for the tendency for documentation to get out of date quickly” lul
17:07:01 <Vorpal> ais523, sec
17:07:26 <fizzie> Roujo: $0- is a syntax, it's just not the bash syntax.
17:07:52 <Roujo> What syntax is it, then? =)
17:07:57 <Vorpal> ais523, that sounds pretty cool (from the introduction, will read the rest in a bit, got some stuff to take care of first)
17:08:08 <ais523> fair enough
17:08:19 <ais523> I am working on an interp, incidentally, but it's not finished ye
17:08:21 <ais523> *yet
17:08:37 <fizzie> Roujo: I don't quite recall, but it certainly was a syntax somewhere. ircII scripts? Something.
17:08:44 <Vorpal> ais523, so unlike Feather it is doable?
17:08:51 <ais523> hopefully I'll eventually have a working hello world that can run successfully more than once
17:08:58 <ais523> Vorpal: *unlike Feather it is possible for me to implement
17:09:04 <Vorpal> fair enough
17:09:10 <ais523> I'm still convinced that Feather is implementable in general, I've just proven myself not up to the task
17:09:19 -!- Bike has joined.
17:09:49 <Roujo> fizzie: Ah, yes. That's the way scripting works on KVIrc. Thanks =)
17:12:43 <Vorpal> ais523, "it should be stored in files encoded in ASCII (more complex encodings are unnecessary due to the highly limited character set)" <-- that seems to work for most languages though... Can only think of a couple of examples that require more than ASCII.
17:13:01 <Gregor> «lol Perl 6»
17:13:01 <Vorpal> and it is impossible to write a Snowflake compiler, due to the possibility that the compiler would be deleted before the program was run (thus leaving the program with no implementation to modify) <-- hm, not quite sure about this one. Would a JIT be impossible?
17:13:12 <ais523> Gregor: you can write << and >> instead
17:13:14 <Vorpal> Gregor, that an some encodings of INTERCAL
17:13:19 <ais523> or qqw/.../
17:13:20 <Vorpal> ais523, oh? okay
17:13:21 <ais523> I think
17:13:26 <Vorpal> then just some encodings of intercal
17:13:33 <ais523> Vorpal: I guess a JIT would be possible, indeed
17:13:35 <Gregor> ais523: Yeah, digraphs and trigraphs worked so well for C ;)

17:14:18 <ais523> hmm, that script interaction isn't going to get annoying at all
17:14:27 <elliott> don't worry, it already has
17:14:35 <elliott> we're on the road to acceptance now
17:15:07 <Phantom_Hoover> can we not just shove a null or a zwsp in the middle of the face
17:15:18 <ais523> clearly, the fix is to give HackEgo ops, so that it can temporarily mute myndzi when erroring out from `? and then unmute em a few seconds later
17:15:29 <elliott> the response was added solely for the purpose of `?
17:15:30 <Vorpal> heh
17:15:31 * ais523 is in the mood for excessively complex fixes right now
17:15:32 <elliott> so I like that solution even more
17:15:42 <ais523> actually it'd do well to stop botloops generally
17:15:45 -!- ChanServ has set channel mode: +o HackEgo.
17:15:50 <elliott> we should have HackEgo always opped
17:16:01 <elliott> it's a challenge, to get it to send arbitrary IRC commands
17:16:12 <Roujo> "As such, there is an effective column of tarnished thread stretching off into infinity."
17:16:16 <Roujo> I like this
17:16:28 <Bike> is the joke that everybody's too horribly lonery to just ask myndzi to stop
17:16:32 <Phantom_Hoover> elliott, wasn't that disabled in the wake of the plazma thing
17:16:46 <Bike> is this going to be another `ls wisdom
17:17:10 <ais523> Bike: it's more that we're esoprogrammers, and that solution is insufficiently creative
17:17:27 <Roujo> myndzi's wisdom explains it:
17:17:27 <Vorpal> ais523, my mind is not in a state for reading the execution model right now. Way too tired to remember the start of the paragraph when I reach the end of it. I guess I'll give you some feedback tomorrow.
17:17:28 <Roujo> `? myndzi
17:17:30 <HackEgo> myndzi keeps us all on our feet
17:17:36 <Bike> uh huh, uh huh, sure
17:17:45 <ais523> Vorpal: fair enough
17:18:28 <Roujo> ais523: Lachine is where I live. boily and I realized that not only do we live in the same city (Montréal), he's the brother of one of my friends. =P
17:18:37 <ais523> Roujo: right
17:18:46 <Vorpal> Roujo, that is pretty funny
17:18:46 <ais523> I figured from the topic that there had to be at least two people there
17:18:49 <ais523> but didn't know what it was
17:19:31 -!- carado has joined.
17:21:28 <Phantom_Hoover> Hmm
17:22:23 <Phantom_Hoover> What does ! in double quotes in bash actually do; and, is it actually worth the inconvenience of not being able to write exclamation marks at all in double quotes?
17:22:44 <shachaf> The answer to your second question is no.
17:23:27 <shachaf> The best part is that you can't even up-arrow and fix the old line.
17:23:49 <Bike> `run echo "!!"
17:23:50 <HackEgo> ​!!
17:23:57 <shachaf> Also it's only in interactive mode.
17:23:59 <Roujo> `run echo !!
17:24:01 <HackEgo> ​!!
17:24:01 <Roujo> Oh
17:24:14 <Bike> oh, it just interpolates the last ccommand.
17:24:16 <Bike> like sudo !!.
17:24:22 <Bike> or... something.
17:24:22 <ais523> $ echo test \ test \ $ echo "!-1" \ echo "echo test" \ echo test \ $
17:24:30 <Roujo> Yeah, that's what it does for me
17:24:31 <ais523> yeah, it's for interpolating previous commands
17:24:38 <ais523> I just checked from the docs
17:24:51 <ais523> bash has a man page, and less's search isn't that awful (although info would be better)
17:24:51 <Roujo> Very useful when you forget sudo
17:25:06 <Roujo> Well, it *was* useful when my "home" key didn't work

17:26:03 <Roujo> Awesome
17:26:05 <ais523> I'm not going to act ignorant and pretend that everyone has man pages even on Windows

17:41:02 <Vorpal> Less than a second
17:41:04 <boily> err -71 is bad. it indeed is an USB cabling error, usually. remove any intermediate steps or hops or everything, change cables, hope for the best.
17:41:20 <Vorpal> boily, oh? Is there a list of these numbers somewhere?
17:41:20 <ais523> boily: did you just look that up, or did you have it memorized?
17:41:24 <Vorpal> Might be useful
17:42:32 <boily> Vorpal: probably. in fact, that may be very useful.
17:42:42 <Vorpal> Anyway I *believe* [189840.988070] usb 6-1.3.2: USB disconnect, device number 91 is my phone disconnecting
17:42:45 <boily> ais523: no, -71 is common and happened to me multiple times.
17:42:55 <ais523> right
17:43:12 <Vorpal> The bus matches, the device doesn't though, but that seems to change on every disconnect or connect
17:43:13 <Roujo> boily works in a linux box. He probably has every man page printed on his desk.
17:43:30 <Vorpal> Roujo, he IS a linux box.
17:43:33 <boily> ais523: I was doing mobile development on android devices, and I had connection problems with one phone, for example.
17:43:34 <Roujo> Nice
17:43:36 <Vorpal> Pretty cool AI
17:43:58 <ais523> Roujo: why would you print man pages? apropos or even grep are better at searching than pper
17:43:59 <ais523> *paper
17:44:16 <boily> some day, I'll build an automated arduinoed facepalm machine, and I'll dedicate it to you guys.
17:44:25 <Vorpal> boily, my phone seems to have a glitchy connector nowdays. Just over a year old too. Charging still works fine though, it is just that data might glitch out of you touch the connector
17:44:40 <Roujo> ais523: What if you don't have access to your computer?
17:44:48 <boily> Roujo: we have a custom man page about how to brew coffee, scotched taped to the wall next to the machine.
17:44:49 <ais523> Roujo: then typically I don't need the content of the man page
17:45:00 <Roujo> ais523: Be Prepared is what I say
17:45:15 <ais523> in the very few cases where I've wanted to check a man page and not had my regular computer, /and/ the computer I was actually using didn't have man pages installed
17:45:24 <boily> Vorpal: then it's like an old dusty NES: try to find the correct ritual that works, and stick to it.
17:45:27 <ais523> there was an Internet connection I could reasonably use, so I looked them up online
17:46:00 <Vorpal> boily, my ritual is charging over USB but running an SSH server on the phone and mounting it over sshfs instead
17:46:01 <Roujo> Right, the Internet
17:46:03 <Roujo> Forgot about that
17:46:10 <Vorpal> boily, works better than bloody MTP anyway
17:46:34 <ais523> Roujo: I actually /can/ conceive of a situation where this wouldn't work, but it's never actually happened so far
17:46:45 <ais523> and there's a limit to the number of things I can carry around just in case
17:46:46 <Vorpal> boily, fuck MTP I say. Why did they think it was a good idea.
17:46:51 <Roujo> I'm curious... What would that situation be?
17:46:54 <ais523> I used to carry out a printout of the FIDE Rules of Chess, for emergencies
17:46:58 <ais523> and it actually came in handy once
17:47:02 <boily> Vorpal: that thing I've been avoiding since its inception?
17:47:04 <ais523> but I don't any more, it's not worth it
17:47:07 <Vorpal> boily, you can't do anything useful over it, like rsyncing your music library.
17:47:10 <ais523> Roujo: programming a Linux-based microcontroller
17:47:18 <Vorpal> boily, most likely
17:47:19 <Roujo> Ah, true
17:47:25 <ais523> some of the labs where I've done it had Windows computers only, and only intermittently working Internet
17:47:34 <ais523> so if the Internet had gone down, I could be left manpageless
17:47:34 <boily> Vorpal: it's useful, therefore you can't.
17:47:48 <Vorpal> boily, quite
17:48:15 <Vorpal> lsusb is a bit on the fence about my phone model:
17:48:17 <Vorpal> Bus 006 Device 050: ID 04e8:6860 Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II], GT-I9300 Phone [Galaxy S III], GT-P7500 [Galaxy Tab 10.1]
17:48:38 <Vorpal> The second one is correct
17:48:40 <ais523> probably those models use the same identifier
17:48:43 <ais523> so lsusb has no way to tell which
17:48:47 <Vorpal> yep most likely
17:49:07 <boily> my desk is manpageless: https://dl.dropboxusercontent.com/u/2023808/IMAG0028.jpg
17:49:17 <Vorpal> ais523, however, it does show up as GT-I9300 in Windows for example (as an MTP device). So that managed to detect it somehow
17:49:26 <Phantom_Hoover> manpage, the page for men
17:49:27 <ais523> boily: did you feel the need to photograph your desk just to prove there were no man pages on it?
17:49:41 <Vorpal> boily, work or home?
17:49:47 <Vorpal> also not enough monitors
17:49:50 <ais523> that looks like work
17:49:55 <Phantom_Hoover> made with VELLUM
17:49:55 <ais523> home wouldn't have a room that shape, most likely
17:50:00 <Vorpal> Hm true
17:50:03 <Phantom_Hoover> and yes Vorpal
17:50:03 <boily> ais523: yes. I have honour!
17:50:11 <Vorpal> Phantom_Hoover, ?
17:50:16 <boily> Vorpal: work.
17:50:18 <Roujo> boily: Nice desk. I like it.
17:50:24 <Roujo> Mine is a bit... messier.
17:50:27 <Phantom_Hoover> this isn't sweden where everyone lives in rooms the size of a small house
17:50:32 <ais523> I actually don't have a desk atm
17:50:41 <ais523> as of yesterday
17:50:47 <boily> elliott: can you voice me, please?
17:50:50 <ais523> the teaching contract thing ended
17:50:55 <elliott> boily: yes
17:51:01 <ais523> so I gave the desk back because I have no reason to use it and the department's short atm
17:51:09 <Vorpal> Phantom_Hoover, eh, not that roomy in my place. I just thought it looked a bit unordered for a work desk
17:51:28 <ais523> (well, I actually returned a key that opens most of the doors in the building, rather than the desk; the desk was in the right place, the problem was that the wrong person was there)
17:51:38 <ais523> Vorpal: my work desk was basically empty
17:51:46 <Phantom_Hoover> this isn't sweden, where all desktop items are aligned upon perfect euclidean boundaries
17:51:47 <ais523> I spent 4 years with nothing there but CPU/monitor/mouse/keyboard
17:52:01 <Vorpal> ais523, what about the HDD?
17:52:02 <boily> `run echo "An ATM is when you're withdrawing money right now at a machine that will steal your relevant info" >wisdom/atm
17:52:06 <HackEgo> No output.
17:52:07 <Bike> i assume swiss desktop items are noneuclidean and gigeresque.
17:52:08 <ais523> and a filing cabinet with a bunch of paper in (most of which has now been recycled or sent for secure disposal)
17:52:12 <ais523> Vorpal: CPU tower container thing
17:52:20 <Vorpal> ais523, XD
17:52:33 <ais523> there was probably an HDD in there too, although all the filesystems I use regularly were NFS
17:52:41 <ais523> *used
17:52:42 <boily> elliott: you mathemanswered me, didn't you?
17:52:46 <Vorpal> ais523, oh? A thin client?
17:52:47 <ais523> well, still use from time to time
17:52:47 <Phantom_Hoover> and dutch desktop items disobey all laws of perspective?
17:53:06 <ais523> Vorpal: no, it was like a powerful quad-core machine or something
17:53:11 <Vorpal> Heh
17:53:19 <ais523> but the storage was all elsewhere, for centralisation reasons
17:53:30 -!- epicmonkey has quit (Ping timeout: 264 seconds).
17:53:34 <Vorpal> ais523, a quad core is not that powerful these days, more like the norm nowdays. Impressive how technology progresses
17:53:46 <Vorpal> Even my phone is quad core after all
17:53:47 <ais523> yeah, but it was powerful at the time
17:54:01 <ais523> it's quite rare that I actually used the power
17:54:07 <Vorpal> My phone is way more powerful than my first computer. By order of magnitudes.
17:54:13 <boily> Roujo: I githubly found you.
17:54:20 <Roujo> ^^
17:54:21 <ais523> probably the only time was when I used Virtualbox for marking the keyloggers
17:54:28 <Vorpal> And my first computer was a first-model iBook, so it isn't like I'm talking about a 386 or such here
17:54:53 <ais523> mostly because rebooting would have been a pain if they went wrong and crashed the kernel
17:54:57 <Vorpal> ais523, marking the keyloggers? What?
17:55:04 <Vorpal> Key loggers? That sounds... nefarious
17:55:06 <ais523> Vorpal: the students were asked to write keyloggers
17:55:08 <ais523> I was asked to mark them
17:55:13 <Vorpal> Heh
17:55:19 <ais523> it's quite a simple exercise that you can give starting-out kernel developers
17:55:27 <Vorpal> Ah yes
17:55:37 <ais523> you only have to hook one interrupt, and it has the basics of things like memory allocation discipline and proper locking
17:55:44 <ais523> and making files in /proc
17:56:06 <Vorpal> ais523, I would assume it works differently for PS/2, serial, USB and so on?
17:56:39 <ais523> I don't think it did in that exercise, possibly they were hooking at a different abstraction level
17:56:44 <Vorpal> ah
17:57:05 <ais523> or else the course designer didn't realise that would be a problem, and it just happened to use the same virtualised port in VirtualBox
17:57:19 <Vorpal> Ah
17:57:22 <ais523> (the students were working in a lab of computers set aside for that sort of thing, which get wiped afterwards)
17:57:34 <ais523> I can believe that the people in charge of the course didn't think it would be a problem
17:57:43 <Vorpal> Right
17:58:12 <Roujo> boily: How do you get that sweet, short URL?
17:58:15 <Roujo> For dropbox%?
17:58:17 <ais523> it was an 11-week course, designed to be worked on at the same time as 5 other courses, about assembler and C and the GNU dialect of C and C++ and Linux kernel development
17:58:19 <Vorpal> Not that you ever see anything but USB these days. Or I guess whatever laptops use for their internal keyboards...
17:58:26 <Vorpal> Hm what *do* those use?
17:58:35 <Vorpal> Internal PS/2 or something better?
17:58:43 <ais523> PS/2 would make sense
17:58:56 <ais523> but it could believably be something else
17:59:11 <Vorpal> ais523, seems like it would be costlier to not reuse the existing USB bus, like almost all bluetooth modules do in laptops anyway
17:59:43 <ais523> Vorpal: well then you need a bunch of hardware to convert the keypresses to the USB protocol
17:59:46 <ais523> might still be cheaper, though, I guess
18:00:02 <Roujo> Ah, found it
18:00:04 <ais523> it would depend on whether complexity on the motherboard or keyboard was more costly
18:00:04 <Roujo> https://dl.dropboxusercontent.com/s/a9v6ve4elg7m36p/20130906_135201.jpg
18:00:25 <ais523> which would likely depend on what connectors happened to be on the motherboard
18:00:33 <Vorpal> Roujo, nice office.
18:00:38 <ais523> because you're probably ordering them COTS, rather than having them custom-made
18:00:44 <Roujo> "office", yeah =P
18:00:53 <Vorpal> Roujo, oh? I thought it wasn't home
18:00:59 <Roujo> More like "mostly open cubicule", but yeah, office
18:01:00 <Vorpal> Roujo, seems like you suffer a 16:9 monitor though
18:01:21 <Roujo> Vorpal: What do you suggest? =P
18:01:24 <ais523> do people actually work on their desktop computers at offices?
18:01:28 <Vorpal> Roujo, 16:10
18:01:31 <ais523> I used my tiny laptop/almost a netbook
18:01:41 <ais523> at least partly because it was outside the firewall
18:01:47 <ais523> thus no real risk if I messed up
18:01:49 <Vorpal> ais523, we have laptops in mostly permanent docking stations at work
18:02:02 <Roujo> ais523: I do. Few people use laptops here.
18:02:06 <ais523> Vorpal: that mostly defeats the point of a laptop
18:02:32 <Vorpal> ais523, They are pretty useless outside of those docks, since they use 180 W PSUs to run at max speed. Battery time is abyssmal. But they are really good when compiling code. Top end quad core i7s
18:02:37 <ais523> I carry my laptop pretty much everywhere
18:02:38 -!- Bike has quit (Ping timeout: 240 seconds).
18:02:41 <Vorpal> And massive SSDs inside
18:02:53 <Vorpal> And as much RAM as you can fit in them.
18:02:59 <ais523> also, the battery time on this is just about sufficient to boot it and enter your password
18:03:02 <Vorpal> I think mine has 12 GB RAM
18:03:04 <ais523> because it's several years old
18:03:13 <ais523> it used to be like 8 hours, but modern batteries lose duration so quickly
18:03:38 <boily> Roujo: sorry, stuck with a hairy XML problem here.
18:03:54 <Vorpal> ais523, anyway I couldn't work on a laptop, too small screen. I regluarly use 2 external 24" 16:10 monitors + the built in laptop 16:9 monitors for various windows
18:03:56 <Roujo> boily: Shave it?
18:04:12 <boily> I really would like to, but my SO wont let me near any blade.
18:04:29 <ais523> Vorpal: I can fit two 80-column programs side by side on this screen
18:04:33 <ais523> which is big enough for me
18:04:39 <ais523> on occasion sometimes I'll split it into 4
18:04:42 <ais523> both vertically and horizontally
18:04:43 <Vorpal> Not enough for me.
18:04:53 <boily> Roujo: but yeah, dropbox.com → dossier Public → clic droit sur l'image → Copier le lien public.
18:05:01 <ais523> Vorpal: what, 80 columns or 4 programs?
18:05:54 <Vorpal> ais523, need an entire monitor to run the various component simulations, since I develop for a distributed embedded system, with like 4 units having monitors on their own, plus a window for the operator panel with the levers and what not. And a window with the IO module simulator
18:06:15 <Vorpal> lots of simulated CAN buses there
18:06:17 <ais523> why does a simulation need a monitor at all?
18:06:22 * ais523 is confused
18:06:45 <Vorpal> ais523, well, if you want to mess with the GUI the users see. It is a control system for mining equipment. And there are several screens in the real machine.
18:06:49 <ais523> ah right
18:07:01 <ais523> yeah, developing GUIs is a decent reason to have a larger monitor than everyone else
18:07:06 <ais523> so you can have their monitor + other things
18:07:14 <ais523> ofc, this is a reason for everyone else to have small monitors
18:07:17 <ais523> otherwise that couldn't be posible
18:08:06 <Vorpal> ais523, plus there is the manging client used in the control room or mine office and the coordination server for remote allocation (and some system configuration), but I can't have non-overlapping windows if I have *everything* open.
18:08:23 * ais523 hopes that "manging" is a typo for "mangling" rather than "managing"
18:08:53 <Vorpal> ais523, the latter alas. It just shows where all the units are on a map, and how much fuel and so on they have
18:09:01 <Vorpal> And where in the drill plans they are
18:09:28 <Vorpal> ais523, since each application also opens a 80x25 terminal window for the log/debug output, the screens fills quickly
18:10:24 <Vorpal> We use a autohotkey script to move all the windows around after starting the simulation. I hate autohotkeys syntax with a passion.
18:10:30 <Vorpal> autohotkey's*
18:11:15 <ais523> this is beginning to sound increasingly WTF over time
18:11:29 -!- Bike has joined.
18:11:30 <ais523> I guess one really good thing about working for a CS department
18:11:45 <ais523> is that the sysadmins / computer technicians (they're the same people there) are really really good at their jobs
18:11:52 <Vorpal> hah
18:11:52 <ais523> because if they weren't, everyone would call them on it
18:12:16 <Bike> in a CS lab i actually managed to print a document to a physical printer
18:12:18 <Bike> triumph, imo
18:12:22 <ais523> I ended up having to need a kernel with custom configuration for a marking script, we explained the problem and they created a VM with a suitably configured kernel
18:12:28 <ais523> and the same filesystems as everything else
18:12:38 <ais523> Bike: at our lab, that'd have something like a 50% chance of working
18:12:41 <Vorpal> ais523, Anyway autohotkey is an a quite reasonable option for moving windows around on Windows. Because afaik there is no other good option for doing that when you press a key combo
18:12:47 <ais523> also it was mostly me who ended up refilling the printers in practice
18:12:50 <ais523> because I printed so many handouts
18:13:09 <ais523> Vorpal: yes, I'm just more amused that the situation became necessary in the first place
18:13:17 <ais523> it'd be nice to just pipe all the terminal output into a monitoring program, for instance
18:13:26 <ais523> that presents it appropriately
18:14:06 <Vorpal> ais523, true, that would be nice. Not sure it would be doable under windows though
18:14:24 <ais523> Vorpal: I was working with Windows console programming recently
18:14:27 <ais523> and my verdict is, "no idea"
18:14:39 <Vorpal> ais523, anyway windows opens windows (pun not intended) in terrible positions by default.
18:14:45 <ais523> Vorpal: it's not even a pun
18:14:48 <ais523> it's what the OS is named after
18:14:55 <Vorpal> true
18:14:57 <Bike> ais523: 50% is more than the usual rate. time before that i tried to print something i had to download drivers. and install via a sh.
18:15:02 <ais523> which is probably a bad idea because the existence of X means that they can't trademark it
18:15:14 <ais523> Bike: we wouldn't have enough perms to do that
18:15:21 <ais523> the actual printing system worked fine
18:15:24 <Bike> on my personal computer, i mean
18:15:27 <ais523> but the queues had a tendency to just get stuck
18:15:28 <ais523> Bike: oh
18:15:41 <ais523> I'd do that via print to PDF + scp + ssh to send it to the printer
18:15:45 <Vorpal> We have a pretty cool printer system at work. You just print to the "Print Anywhere" device, then go to a printer and swipe your RFID door key thingy
18:15:47 <Bike> okay, well, that sucks.
18:15:51 <Vorpal> then you get a list of your printer queue
18:15:59 <Vorpal> And can select to print whatever
18:16:00 <ais523> but I was talking about from the labs themselves
18:16:15 <ais523> but it's very rare I needed to print anything other than handouts for students and marksheets
18:16:24 <ais523> and those could most easily be printed in the lab anyway
18:16:41 <ais523> (at least partly to stop people stealing them before I had a chance to collect them from the printer)
18:16:51 <Bike> also you know what's weird? the way we have a desktop metaphor and then cover our desktops in windows
18:16:55 <ais523> (which is unlikely but I took data protection seriosuly, especially when marks are involved)
18:17:38 <Bike> like, i have a physical desk, and there are hardly any windows on it at all.
18:17:46 <Vorpal> ais523, where do you work now?
18:17:57 <Vorpal> Bike, XD
18:18:04 <ais523> Vorpal: currently I'm finishing up a PhD, so at home
18:18:06 <Bike> maybe back in the 60s there was a fad of desks made of glass
18:18:09 <Bike> this is the only logical explanation
18:18:10 <Vorpal> ais523, ah
18:18:25 <Bike> some kind of system of wheels to move glass around the surface
18:18:27 <Vorpal> Bike, I have seen living room tables made of glass
18:18:53 <Vorpal> Well the surface that is, usually not the legs
18:19:05 <Bike> in the desktop metaphor that would be having your desktop background be a view into your CRT or some shit (back when we used crts)
18:19:07 <Vorpal> Though that would be cool and probably dangerous
18:19:41 <Bike> man. remember crts?
18:19:42 <Bike> fuck crts.
18:19:43 <Vorpal> yes
18:19:49 <Vorpal> I hate them with a passion
18:20:02 <Bike> how is something with an "electron gun" so damn inconvenient.
18:20:06 <Vorpal> Never really sharp, always slightly blurry and headache inducing
18:20:18 <Bike> if i had an electron gun i'd just shoot it all the time
18:20:34 <ais523> good CRTs actually have better image quality than good LCDs
18:20:39 <boily> if I had an electron gun, I'd make myself instant hot-dogs.
18:20:41 <ais523> but people preferred LCDs because they took up less space
18:20:41 <Vorpal> Bike, it isn't called a "gun" in Swedish. We use the terms "anod" and "katod"
18:20:52 <Bike> my grocery clerk? a professor? someone asking me out on a date? BAM electrongun'd.
18:20:52 <ais523> boily: I'm not sure if you can cook a hot dog effectively with beta-radiation
18:20:52 <Vorpal> Pretty sure they are used in English as well
18:21:03 <ais523> Vorpal: "anode", "cathode"
18:21:06 <Bike> Vorpal: anode and cath- yeah.
18:21:13 <boily> ais523: cooking it effectively is not the point.
18:21:16 <ais523> technical terms for referring to electrodes at particular voltages
18:21:27 <Vorpal> ais523, that depends on the quality of the LCD I would say. IPS panels can be pretty damn good
18:21:27 <boily> (irradiating hot-dog sausages, otoh... :D)
18:21:46 <Vorpal> ais523, I moved over to IPS at home after getting used to it at work
18:22:52 <Fiora> Bike: would you electron-gun iverum
18:22:58 <Vorpal> I can heartily recommend Dell UltraSharp U2413 btw. Dell UltraSharp U2412M is a bit cheaper (mostly due to the fact that it is sRGB instead of wide gamut) but still really good
18:23:06 <Bike> Fiora: you /and/ him, babe
18:23:23 <Fiora> that sounds painful :<
18:23:46 <ais523> Vorpal: anyway we wouldn't use "anode"/"cathode" to talk about an electron gun generally in English; it'd be like casually describing a computer by what sort of motherboard it used
18:23:57 <Bike> i don't think electron guns actually do anything to people
18:24:20 <Vorpal> ais523, hm I guess there is the term "elektronstrålerör" now that I think about it. Which would be "electron beam tube"
18:24:51 <Vorpal> or even electron ray tube
18:24:56 <Vorpal> both translations work
18:25:05 <Bike> i mean, electrons are like, small,, man.
18:26:03 <ais523> Bike: beta rays are actually pretty dangerous
18:26:12 <ais523> mostly via corrupting DNA
18:26:15 <Bike> orly
18:26:28 <Bike> Fiora: ok, i'll shoot him first to make sure it's safe.
18:26:46 <Fiora> beta particles don't sound very safe
18:26:53 <ais523> actually, alpha/beta/gamma rays are all dangerous; alpha are the most damaging if they get inside the body, but also get stopped very easily
18:27:11 <ais523> like, even a piece of paper gives pretty good shielding from alpha rays
18:27:28 <ais523> so beta are the most dangerous if you're near the source, and gamma from a long distance
18:27:51 <Vorpal> ais523, what about neutrons?
18:28:02 <ais523> unless you pointed an alpha ray directly at an open wound, but don't do that
18:28:04 <ais523> Vorpal: I don't know
18:28:04 <Vorpal> As happens in a chain reaction with uranium and such
18:28:18 <Vorpal> What is that radiation even called?
18:28:22 <ais523> I assume that there are people who know how dangerous they are, but I'm not one of them
18:30:01 <Fiora> neutrons are just called neutrons I thikn
18:30:08 <Phantom_Hoover> yes
18:30:18 <Phantom_Hoover> and unlike the others there are different kinds iirc
18:30:21 <Bike> imo zeta rays.
18:30:27 <Vorpal> Phantom_Hoover, oh?
18:30:54 <ais523> there's only one sort of neutron AFAIK
18:31:06 <Phantom_Hoover> yeah, but they can have different energies
18:31:07 <ais523> I guess there are antineutrons too but they tend not to exist very much
18:31:18 <ais523> Phantom_Hoover: well, in that case, there are different kinds of gamma ray too
18:31:21 <Bike> wow, way to be discriminatory ais.
18:31:24 <Phantom_Hoover> i guess alpha, beta and gamma are all pretty constrained by the nuclear processes that emit them
18:31:47 <ais523> Bike: ?
18:31:53 <Bike> nevermind
18:31:59 <Bike> can't neutrons have differente spin or some shit
18:32:03 <Bike> all these particles fuckcing spin
18:32:11 <Phantom_Hoover> yeah but that doesn't matter
18:32:16 <Bike> oh
18:32:30 <Phantom_Hoover> but afaik the interactions that lead to alpha/beta decay have fairly strict requirements
18:32:39 <Fiora> yeah, most alpha particles have around the same energy
18:33:16 <Phantom_Hoover> there's an isotope of tantalum which should in theory be ridiculously unstable, but because of this bizarre convergence of different effects is very very stable
18:33:23 <Fiora> ta-180m~
18:33:35 <Phantom_Hoover> fuck you i loved it first
18:33:36 <Bike> the fuck is tantalum even for
18:33:36 <Fiora> I love those weird cool isotopes like that
18:33:45 <Phantom_Hoover> Bike, capacitors hth
18:33:54 <Bike> god fuck capacitors
18:34:03 <Fiora> :<
18:34:14 <Bike> j/k, i <3 capacitance.
18:34:23 <elliott> Phantom_Hoover: was that during your metallurgy hipster phase
18:34:44 <Fiora> or like, the reason that technetium doesn't have any stable isotopes
18:34:49 <Fiora> or the be8/c12 resnoance
18:34:51 <Fiora> or halo nuclei
18:34:54 <Bike> i'm really into niobium, you've probably never heard of it, etc
18:34:58 <Fiora> (nuclear physics is so wonderful)
18:35:20 <ais523> Bike: there are such things as element hipsters?
18:35:29 <ais523> err, *elliott:
18:35:45 <ais523> sorry, I have more scrollback than Vorpal but I read it backwards
18:35:48 <ais523> so I can get a little out of context sometimes
18:35:57 <boily> Roujo: could you voice me? elliott is being a mathematician today.
18:36:00 <Vorpal> ais523, I have 1000 lines per channel iir
18:36:02 <Vorpal> iirc*
18:36:38 <Bike> ais523: lanthanides are way better displayed on vinyl
18:36:46 <ais523> Vorpal: are you not aware that "Vorpal has no scrollback" is a #esoteric meme?

18:38:11 <boily> HackEgo: VOICE! NOW!
18:38:15 <boily> HackEgo: pretty please.
18:38:25 <ais523> boily: why do you want voice so much anyway?
18:38:44 <boily> ais523: equilibrium of the forces. and I'm jealous of Roujo's status :D
18:38:50 <Bike> we should download irssi into hackego and have it join. it will, of course, be opped
18:39:12 <ais523> I don't think hackego knows its own IRC password
18:39:20 <Bike> that's deep.

18:42:07 <Roujo> All I know is that I got voice while commenting the race
18:42:14 <Roujo> Along with boily
18:43:26 <ais523> hmm… what might be interesting would be an IRC flag/permission-like thing
18:43:40 <ais523> that does nothing at all, except allow you to turn it on and off on other people
18:43:46 <ais523> it'd be an interesting exercise in social dynamics
18:43:46 <Roujo> That would be awesome
18:44:11 <Roujo> Over on SlashNET, there's a channel where anyone that gets in gets ops
18:44:30 <Roujo> So you just have to join it, and you get ops
18:44:31 <boily> ~duck slashnet
18:44:31 <metasepia> SlashNET is a medium-sized, independently operated Internet Relay Chat (IRC) network.
18:44:43 <Roujo> That's also an interesting social experiment
18:44:47 <Bike> is slashnet one of those anti-serv places
18:44:55 <boily> Roujo: you heretic. there is one network, and the network is Freenode.
18:44:58 <Roujo> Nope, Services are there
18:45:03 <Bike> ok
18:45:04 <ais523> Roujo: heh; I remember the terms and conditions for quakenet
18:45:23 <ais523> which pretty much explicitly say "don't do that, are you idiots, if you op everyone in your channel we refuse to help if someone screws it up (which they will)"
18:45:27 <ais523> well, they don't use the same language
18:45:33 <Roujo> ^^
18:45:44 <Roujo> I've yet to see anyone abuse the op powers
18:46:03 <Roujo> Which is impressive, imo
18:46:10 <ais523> it depends on which networks you go to
18:46:12 -!- pikhq has quit (Read error: Operation timed out).
18:46:24 <ais523> I've been on the receiving end of op abuse in other channels before now
18:46:24 <Roujo> On the everyone-is-an-op channel, I mean
18:46:43 <Roujo> I got k/b'd from other channels for no reason before =P
18:46:46 <Roujo> Well, "no reason"
18:46:48 <ais523> my normal technique for dealing with it is to avoid the channel for a long time in order to worry people into thinking that I was seriously offended
18:46:52 <Roujo> 1) "I thought you were someone else"
18:46:58 <Roujo> 2) "I don't know you, so get out"
18:47:03 -!- pikhq has joined.
18:47:05 <ais523> especially in channels where the vast majority of people have autojoin, and joke kicks are comon
18:47:07 <ais523> *common
18:47:10 <Roujo> Heh
18:47:20 <ais523> for 2), it's called setting invite-only (or channel key)
18:47:23 <ais523> 1) is understandable though
18:47:40 <Roujo> Yeah =P
18:47:45 <Roujo> It was just pretty random
18:47:48 <Roujo> Since I just got in
18:48:11 <Roujo> It was about an old community I was a part of, so I was catching up, talking to people
18:48:28 <Roujo> And then some op came back, saw that I was called Skynet, panicked and k/b'd me
18:48:58 <Bike> terrified of the terminator menace
18:49:23 <ais523> from my point of view: if Skynet really does become reality and start taking over the Internet (and then the whole world by proxy)
18:49:34 <ais523> if it actually thinks it's safe for it to use its real name, we're probably screwed no matter what
18:49:38 <ais523> so there's no point in worrying about it
18:50:50 <Roujo> Good point
18:51:18 <Bike> guess we're going to have to travel back in time to tell the op this.
18:51:22 <Roujo> ais523: We were talking about how I became Skynet just yesterday
18:51:47 <Roujo> When you suggested that I /nick Skynet to scare Darth_Cliche, back when I played BlogNomic
18:51:56 <ais523> wow, I'd mostly forgotten that
18:52:04 <Roujo> So that blognomicbot would show "Players watching the game: Skynet"
18:52:17 <ais523> I caused enough controversy when I started using callforjudgement on blognomic IRC, before I was a player
18:52:20 -!- ais523 has changed nick to callforjudgement.
18:52:25 <Roujo> She didn't remember it at all, either =P
18:52:31 <Bike> blognomic controversy
18:52:33 <callforjudgement> the nick stuck, but I'm not allowed to use it for nomic any more
18:52:47 <Roujo> I remember, though. She came in and, again, k/b'd me. =P
18:53:03 <boily> ~duck blognomic
18:53:04 <metasepia> Software description: support applications for various blognomic dynasties (Python).
18:53:04 <Roujo> Nevermind the fact that I had ops, so I was (probably) a known player =P
18:53:05 <Roujo> But eh
18:53:11 <Roujo> Heh
18:53:19 <Roujo> boily: http://blognomic.com/
18:53:21 * boily kicks DDG in the self-referential definitions
18:53:29 -!- mnoqy has quit (Read error: Operation timed out).
18:53:37 -!- mnoqy has joined.
18:53:45 <callforjudgement> blognomic's the gateway nomic for addicting people to nomic
18:53:49 <Roujo> Yup
18:54:03 <callforjudgement> basically, because a) it's easy to play, and b) it's fun the first few dynasties
18:54:05 <callforjudgement> then it gets repetitive
18:54:17 <Vorpal> <ais523> I caused enough controversy when I started using callforjudgement on blognomic IRC, before I was a player <-- what does that do?
18:54:25 <boily> I think I tried nomic once with my bro and another guy (or girl, or human. probably human). it was... politico-confuzzling.
18:54:26 <Roujo> Or your win gets papered over and you resent the game forever
18:54:44 <Roujo> Vorpal: Call for Judgement, or CFJ, is an in-game term
18:54:48 <Roujo> Which makes the nick confusing =P
18:54:49 <callforjudgement> Vorpal: in Nomic, a call for judgement is what happens when there's a dispute about the rules and they want someone to resolve it
18:55:02 <callforjudgement> now, in BlogNomic specifically, they felt it'd be useful for people to make anonymous CFJs
18:55:05 <Roujo> boily: We should play together one day.
18:55:17 <callforjudgement> so that they didn't give away secret information
18:55:17 <Roujo> Heck, I played Nomic with Pouti for quite some time
18:55:19 <Vorpal> callforjudgement, heh
18:55:44 <callforjudgement> (the standard example was in a Werewolf/Mafia game; if one of the Mafia felt that something was unfair to their team, they couldn't exactly bring up the point publicly)
18:55:50 -!- Taneb has joined.
18:56:02 <callforjudgement> thus, they had a user account, "callforjudgment" (US spelling), for the purpose of making them, that anyone could use
18:56:16 <callforjudgement> someone (possibly multiple people) started trolling via it, so it got deactivated
18:56:20 <callforjudgement> then I thought it'd be funny to use on IRC
18:56:34 <callforjudgement> to show that I was anonymous
18:56:42 <callforjudgement> except I didn't notice the spelling difference, so I did it with UK spelling
18:57:01 -!- callforjudgement has changed nick to ais523.
18:57:05 -!- ais523 has changed nick to CallForJudgement.
18:57:07 * CallForJudgement fixes caps
18:57:22 <CallForJudgement> anyway, things lead to other things, and it's probably my primary nick now
18:58:55 <Vorpal> CallForJudgement, really?
18:58:57 <Vorpal> Hm
18:59:02 <boily> Roujo: there's the OUMF going on. retrogaming night today!
18:59:07 <CallForJudgement> it's less taken on average than "ais523"
18:59:09 <CallForJudgement> for one thing
18:59:24 <CallForJudgement> (which, as is well-known by now, was randomly generated by the University's computer system)
19:00:23 <CallForJudgement> there's also "scarf", but mostly just because I noticed it wasn't taken
19:01:09 -!- Bike has quit (Ping timeout: 256 seconds).

19:09:38 <CallForJudgement> I may as well read them all anyway
19:10:19 <boily> I seem to have missed the USB sushi antediluvian craze...
19:12:32 <CallForJudgement> boily: I saw it advertised once
19:12:38 <CallForJudgement> not sure exactly what it was, because I didn't buy it
19:13:48 <boily> in any case, your quotes are ready. you can peruse the PDF.
19:16:34 <CallForJudgement> hmm, we need a Snowflake-related quote in the qdb
19:16:45 <CallForJudgement> so that I can mark the passage of qdb times by the esolangs being discussed
19:17:07 <mnoqy> quick someone say something funny about snowflake
19:17:16 <CallForJudgement> (I'm surprised that so long has gone since Radixal!!!!)
19:17:27 <CallForJudgement> that was 825
19:18:23 <CallForJudgement> actually, I think I have a good definition for what makes a good esolang
19:18:26 <boily> why a snowflake? what is Radixal?
19:18:33 <boily> ~eval primeFactors 825
19:18:34 <metasepia> [3,5,5,11]
19:18:47 <CallForJudgement> it's a language which, at the point in time at which it was created, cannot be programmed in using programming techniques that already exist
19:18:54 <CallForJudgement> thus, brainfuck was a good esolang when created
19:19:06 <CallForJudgement> but BF derviatives are not good esolangs, because techniques for BF are well known now
19:19:56 <solidoodlesuppor> do esolangs ever get used for legit cryptography?
19:20:03 <solidoodlesuppor> I feel like you hide something fun in a cook book program
19:20:04 <CallForJudgement> I doubt it
19:20:15 <CallForJudgement> esolangs mostly exist to make things hard to understand on the surface
19:20:28 <Roujo> Snowflake uses kittens to reverse stack polarity.
19:20:32 <CallForJudgement> whereas nowadays, legit cryptography is about being mathematically unbreakable even if you know what you're doing
19:20:38 <Roujo> That's enough to make it a good esolang in my book.
19:21:10 <Roujo> Then again, few people even read my book.
19:21:13 <Roujo> But eh =P
19:21:37 <solidoodlesuppor> Does anyone do esolangs for a living?
19:21:40 <Roujo> CallForJudgement: Good enough of a quote for you?
19:21:41 <solidoodlesuppor> seems like such a strange place
19:21:54 <Roujo> solidoodlesuppor: Does VB count?
19:21:59 <solidoodlesuppor> HAH
19:22:04 <CallForJudgement> Roujo: :)
19:22:05 <Taneb> How about PHP?
19:22:19 <Roujo> Right, PHP. Qualifies since there's still no known good programming technique to use.
19:22:20 <CallForJudgement> solidoodlesuppor: there was exactly one instance where an esolang made commercial success
19:22:22 <boily> Taneb: we're talking programming.
19:22:24 <CallForJudgement> was it… biota?
19:22:28 <boily> (</snob>)
19:22:32 <CallForJudgement> it got designed for a purpose, then solved
19:22:35 <CallForJudgement> err, sold
19:22:36 <boily> Taneb: also, your quotes were reformatted.
19:22:41 <Taneb> :O
19:22:42 <CallForJudgement> mostly it's for fun or for reasearch, though

19:22:53 <CallForJudgement> also arguably the $25,000 I won from Wolfram Research was esolanging
19:23:13 <Roujo> CallForJudgement: You won 25k from them? Awesome! =D
19:23:21 <CallForJudgement> I think part of the reason I got there first is that people were trying to see it as a maths/CS problem
19:23:26 <CallForJudgement> rather than an esoprogramming problem
19:23:27 <solidoodlesuppor> seems like you could write a nasty computer virus in biota
19:23:36 <CallForJudgement> (understandable, because most people don't know what esoprogramming is)
19:23:37 <Phantom_Hoover> the rewards for propping up wolfram's ego are great
19:23:55 <CallForJudgement> Phantom_Hoover: well I kind-of fell out with him
19:24:05 <Phantom_Hoover> as are the costs
19:24:11 <Phantom_Hoover> why did you fall out
19:24:38 <CallForJudgement> basically because he seemed to consider the entire problem as a yes or no thing
19:24:39 <Taneb> CallForJudgement, I thought you were a newb! I have not been paying attention
19:24:45 <CallForJudgement> when it's much more nuanced than that
19:24:53 <CallForJudgement> Taneb: not enough to know my alternative nick, indeed
19:25:03 -!- k_k_k has quit.
19:25:09 <CallForJudgement> but I haven't been here for weeks
19:25:13 <CallForJudgement> so I'm probably a newb anyway :)
19:25:24 <Taneb> I have never seen you use that nick before
19:25:35 <Phantom_Hoover> oh, so this is the wrapper controversy
19:25:38 <CallForJudgement> I don't use it on Freenode much
19:25:46 <CallForJudgement> Phantom_Hoover: nah, the controversy happened ages ago
19:25:58 <CallForJudgement> I'm not annoyed at the controversy, I'm annoyed at Wolfram for not even noticing its existence
19:26:07 <Phantom_Hoover> yes, that's what i meant
19:26:08 <CallForJudgement> also for thinking that something that runs in O(2^2^n) might be viable
19:26:25 <CallForJudgement> that computational class is too high for most people to comprehend
19:26:30 <Taneb> CallForJudgement, by the end of the month I'll be attending the University of York
19:26:38 <CallForJudgement> Taneb: is that relevant somehow?
19:26:42 <Taneb> No
19:26:45 <CallForJudgement> fair enough
19:26:48 <Taneb> Just thought you may have missed it
19:26:51 <CallForJudgement> I did
19:27:02 <CallForJudgement> always important to know whether there's anyone of importance in hexham or not
19:27:13 <CallForJudgement> and if you're in york, there's only a need to figure it out wrt elliott
19:27:37 <Taneb> Can you, as a former student, give me studency advice?
19:28:09 <CallForJudgement> well I was really bad at anything but the academic stuff
19:28:20 <CallForJudgement> I somehow managed to miss Fresher's Week altogether
19:28:32 <Phantom_Hoover> we didn't even have fresher's week in warwick
19:28:33 <CallForJudgement> and basically just stayed independent of everyone for like a year, it was pretty boring
19:28:37 <solidoodlesuppor> What did wolfram do wrong?
19:28:39 <solidoodlesuppor> is list
19:28:39 <Phantom_Hoover> it was folded into the normal first week
19:28:42 <solidoodlesuppor> *lost
19:28:42 <CallForJudgement> so I filled in the time by learning INTERCAL
19:28:59 <CallForJudgement> this also explains why the early ais523 era of C-INTERCAL was developed on SunOS
19:29:08 <CallForJudgement> I also decided to learn UNIX at the same time
19:30:43 <Taneb> solidoodlesuppor, basically, CallForJudgement proved a very small system (that Wolfram was interested in) Turing-complete under the assumption that the tape started as some easily computable sequence
19:30:57 <CallForJudgement> Taneb: well, "easily" is relative
19:31:22 <Taneb> solidoodlesuppor, and some people, Wolfram included, didn't like that very much
19:31:33 <solidoodlesuppor> oh. I heard he can be that way...
19:31:59 <Roujo> Taneb, CallForJudgement: Is there anywhere I could read about this?
19:32:03 <Roujo> Sounds interesting
19:32:17 <Taneb> http://en.wikipedia.org/wiki/Wolfram's_2-state_3-symbol_Turing_machine#Proof_of_universality
19:32:28 <Roujo> http://www.wolframscience.com/prizes/tm23/images/prizeAnnouncement.png
19:32:29 <Roujo> Woot
19:32:34 <CallForJudgement> Wolfram Science have their own page about it
19:32:39 <CallForJudgement> as well
19:32:43 <CallForJudgement> Wikipedia's pretty neutral on the subject, though
19:32:49 <CallForJudgement> which is impressive given how polarized the sides got
19:32:57 <CallForJudgement> I stayed entirely out of it myself (mostly just watched, or ignored it)
19:32:59 <CallForJudgement> on Wikipedia, that is
19:33:06 <CallForJudgement> but there was systematic vandalism there for a while
19:33:24 <Vorpal> <CallForJudgement> also for thinking that something that runs in O(2^2^n) might be viable <-- wtf? He thought that was viable? I guess for very very small n
19:33:26 <CallForJudgement> come to think of it, this probably explains why the universality thing has 12 citaitons
19:33:27 <CallForJudgement> *citations
19:33:42 <CallForJudgement> Vorpal: I don't think he thought that was viable; rather, he just didn't think of checking the computational class at all
19:33:49 <Vorpal> Ah
19:34:03 <CallForJudgement> there's at least one fallacious proof in ANKOS because he ignored the initialization requirements of the rule 110 proof
19:34:25 <Vorpal> what is ANKOS?
19:34:31 <boily> ~duck ankos
19:34:32 <metasepia> A New Kind of Science is a best-selling, controversial book by Stephen Wolfram, published in 2002.
19:34:43 <Vorpal> Ah
19:35:14 <CallForJudgement> the funny thing is, I fixed it in my head
19:35:17 <CallForJudgement> told him about it over the phone
19:35:21 <CallForJudgement> but have never publicly released the fix
19:35:24 <CallForJudgement> somehow I like things that way
19:36:34 <Roujo> Heh =P
19:36:34 <Taneb> Roujo, as a Canadian, can you give me studency tips?
19:36:40 <Roujo> Taneb: Studency?
19:36:48 <Taneb> The state of being a student
19:36:49 <CallForJudgement> being-a-student-ness, I guess
19:36:53 <Roujo> Oh
19:36:55 <Roujo> Well
19:36:58 <Roujo> Erm
19:37:04 <Roujo> I'm not a student anymore, mind you
19:37:17 <Roujo> And even when I was... I tended to not follow proper studency
19:37:28 <Roujo> Didn't do homework, didn't really study... =/
19:37:43 <Taneb> Is your advice gonna be "don't do what I did"?
19:37:43 <Roujo> So I'm not sure any advice of mine would be worth much
19:37:47 <Roujo> Well
19:37:51 <Roujo> No
19:38:13 <Roujo> Here's my advice: "Never stop being curious."
19:38:21 <Taneb> That is good advice
19:38:46 <Taneb> Vorpal, as someone who probably was a student but I cannot actually remember, can you give me studency tips?
19:38:48 <Roujo> I'm a bit... lazy at times. But this is what saved me.
19:38:49 <solidoodlesuppor> Taneb: How did you get your nick indented....?
19:38:59 <Roujo> Indented?
19:39:02 <Phantom_Hoover> <CallForJudgement> there's at least one fallacious proof in ANKOS because he ignored the initialization requirements of the rule 110 proof
19:39:04 <Phantom_Hoover> details, ais
19:39:05 <Taneb> I did?
19:39:06 <Phantom_Hoover> details
19:39:28 <CallForJudgement> Phantom_Hoover: he produced a turing machine (2,5 I think) which, when run on an empty tape, produces the pattern that rule 110 produces on an empty tape
19:39:33 <CallForJudgement> and claimed that the turing machine is TC
19:39:37 <CallForJudgement> it is, but that doesn't prove it
19:39:47 <Vorpal> Taneb, hm, find friends early who are interested in studies rather than living the student life I guess. If that is what you want.
19:40:12 <CallForJudgement> I found friends eventually, and got on well with them, for academic project purposes
19:40:16 <Vorpal> Taneb, not really sure what kind of tips you want
19:40:21 <CallForJudgement> we went and collaborated to subvert the group project marking system
19:40:44 <Taneb> Vorpal, mainly I'm just a bit nervous because it's a big change for me
19:40:47 <Vorpal> CallForJudgement, I'm playing paper & pen roll playing with a couple of them nowdays even after university.
19:41:04 <Roujo> Oh, about being a student... Yeah, friend are important. Surround yourself with people you want to be like, it helps to soak up their interest/intensity like a sponge. =)
19:41:15 <Vorpal> CallForJudgement, And we usually meet up a couple of times every year for a dinner or such.
19:41:19 <CallForJudgement> also don't worry too much about getting it right first time
19:41:31 <CallForJudgement> universities aren't like schools where you're stuck with the same few people forever
19:41:46 <Vorpal> Taneb, learn LaTeX if you don't already know it. You might not need it at the start, but it will get invaluable pretty soon
19:41:48 <Roujo> Taneb: Being around people who do studies-related stuff for fun is a good way to make the studies themselves fun
19:42:13 -!- itsy has quit (Quit: itsy).
19:42:34 <CallForJudgement> Vorpal: oh yes, good advice
19:42:39 <CallForJudgement> although it can be put off several years
19:42:56 <Vorpal> CallForJudgement, we are using a custom rule system, one of us (not me) is a rule set collector and nerd, so he made his own system instead of using an existing one. It works pretty well from what I can tell.
19:43:31 -!- Bike has joined.
19:43:44 <Vorpal> CallForJudgement, I had good use of it in the second half of the second year and from that point onwards I would say
19:43:57 <Bike> is CallForJudgement still ais
19:44:09 <Vorpal> Bike, no, he evolved
19:44:10 <CallForJudgement> Vorpal: from my point of view it was pointless because everyone else used Word even when we specifically told them not to
19:44:13 <Bike> :o
19:44:26 <Bike> just wondering if someone else is nicked callforjudgment as a joke before i ask ais a question
19:44:29 <Vorpal> Look! ais523 is evolving. He is turning into a CallForJudgement.
19:44:49 <CallForJudgement> I had to merge nine separate files, eight of which were Word files, in order to write a report
19:44:51 <CallForJudgement> under huge time pressure
19:44:52 <Vorpal> (sorry I never played much pokemon, I don't remember how the wording goes)
19:45:04 <Vorpal> CallForJudgement, ouch
19:45:07 <Bike> i haven't played pokemon in years. you know why? because i'm not a NERRRRRD
19:45:26 <CallForJudgement> the way I did it was to tell people to stop editing for a while, then run the Word-generated HTML through Tidy, then open it in Emacs and run a bunch of regexes on it interactively
19:45:30 <Vorpal> Bike, I only ever played one game, and in an emulator
19:45:38 <Vorpal> I never owned any handheld, or any console
19:45:43 <Bike> geez
19:45:48 <Bike> i at least played on a Real Console
19:45:48 <CallForJudgement> I qualified for the Pokémon World Championships in 2011 via coming top 8 in the UK
19:45:52 <Vorpal> CallForJudgement, holy crap
19:46:07 <CallForJudgement> Vorpal: how did you not know this? I think I've mentioned it in-channel before
19:46:08 <Bike> is there anything ais can't do
19:46:16 <CallForJudgement> Bike: qualify in 2013, apparently
19:46:17 <Vorpal> CallForJudgement, no I meant the Tidy stuff
19:46:21 <Bike> point
19:46:25 <Vorpal> CallForJudgement, that is what I went "holy crap" at
19:46:26 <Bike> anyway i'm going to ask my question
19:46:38 <CallForJudgement> Vorpal: Tidy has a command line option specifically for cleaning up some of the worst excesses of Word
19:46:42 <Bike> which is just, you do cool hardware stuff, i'm in babby's first hardware class, do you have any suggestions for what to attempt to do with my fpga
19:46:58 <Vorpal> CallForJudgement, anyway
19:47:07 <Gregor> Bike: Eat it.
19:47:07 <CallForJudgement> Bike: well the hello world for an FPGA (or similar hardware things) is to toggle one of the GPIOs between 0 and 1 every second
19:47:09 <Gregor> FPGA is food.
19:47:12 <Vorpal> I used LyX mostly, and for stuff I was the only person working on
19:47:20 <Bike> mm, i haven't done anything with the clock yet
19:47:23 <Vorpal> I never had to work on stuff with 8 people editing at the same time
19:47:38 <Bike> my most advanced design so far is something that turns off a different ssd based on which button is pressed.
19:47:40 <Vorpal> CallForJudgement, thought it was every half second?
19:47:46 <CallForJudgement> Bike: FPGAs suck at asynchronous, you probably want to use the clock
19:47:49 <CallForJudgement> Vorpal: tbf I doubt it matters
19:47:50 <Bike> Gregor: i read an article on anosmia in birds the other day and thought of you.
19:47:55 <CallForJudgement> it's like whether you put the comma in the hello world or not
19:48:01 <Bike> CallForJudgement: yeah, i meant, i haven't done anything complicated enough to warrant a clock :/
19:48:23 <Bike> i was hoping for my next thing i could have the ssds display the number input on the switches in base four
19:48:23 <Vorpal> CallForJudgement, but that is hugely important!
19:48:26 <CallForJudgement> Bike: I feel a bit conflicted here because I had an argument with my PhD supervisor yesterday
19:48:30 <Bike> which requires clock because of the way the ssds are muxed
19:48:33 <Bike> CallForJudgement: oh?
19:48:43 <CallForJudgement> where he was claiming that I should abandon talking about asynchronous hardware because it wouldn't run on our FPGA
19:48:51 <CallForJudgement> and yet it's a more natural fit for the mathematical model
19:48:55 <Bike> huh
19:49:08 <CallForJudgement> (actually, the problem is that all the existing formalisms of delay-insensitive asynchronous hardware suck)
19:49:08 <Bike> well, i'm interested in clockless stuff, but it's a pretty abstract interest given my level of capability
19:49:13 <Vorpal> CallForJudgement, there isn't much async hardware though, is there?
19:49:15 <CallForJudgement> Bike: so am I
19:49:17 <CallForJudgement> Vorpal: no
19:49:22 <CallForJudgement> but it's OK, this is /theoretical/ computer science
19:49:29 <Bike> right except you're, like, a phd candidate, you know more9 things than i do
19:49:56 <Vorpal> CallForJudgement, I mean in a computer. Apart from some stuff dealing with races between different clocks and such, and IO, all the computation in a normal computer happens sync mostly, right?
19:49:59 <Bike> right now i just need to do my homework which is "how much current is running through the wire in this circuit" and shit like that. v. basic

19:50:42 <CallForJudgement> which is impossible without dropping to async somewhere
19:50:43 <Phantom_Hoover> oh btw Taneb don't worry, you cannot possibly be worse-prepared for studenting than me and i managed ok
19:50:44 <Vorpal> CallForJudgement, right, what about interrupts?
19:50:52 <Bike> mnoqy: only itidi.
19:50:56 <CallForJudgement> Vorpal: they don't work until the next clock cycle
19:50:59 <Taneb> Phantom_Hoover, this sounds like there are a fair few interesting anecdotes
19:51:00 <Vorpal> Ah right
19:51:08 <CallForJudgement> which is unsurprising, given that computers can't run instructions between clock cycles anyway
19:51:17 <boily> mnoqy: like hungarian soup, I conflagrated them.
19:51:29 <Bike> wow! i seriously forgot my pen. wow. can't do shit now. nobody has a pen in an EE building.
19:51:56 <Vorpal> CallForJudgement, arguably they do in the sense that an instruction can be split over several cycles or several instructions can execute in one?
19:52:01 <Vorpal> CallForJudgement, don't buses themselves usually have clocks btw?
19:52:04 <Phantom_Hoover> Taneb, not really, i just had very little experience living alone when i left and i adapted pretty quickly to it
19:52:17 <Taneb> Phantom_Hoover, okay
19:52:24 <Vorpal> CallForJudgement, anyway is the benefit of async hardware worth it?
19:52:37 <CallForJudgement> Vorpal: I have no idea
19:52:43 <Bike> personally i'm partly interested in async because ~brainz~
19:52:47 <CallForJudgement> that's the problem with theoretical designs
19:52:53 <mnoqy> is this a biologist thing
19:52:54 <CallForJudgement> in theory, it runs faster on average
19:52:59 <Bike> mnoqy: maybe.............
19:53:01 <CallForJudgement> because synchronous hardware runs at worst-case speed
19:53:08 <CallForJudgement> and asynchronous hardware at average-case on average
19:53:17 <Vorpal> I seem to remember reading about a MIPS CPU that was async
19:53:20 <CallForJudgement> but the circuits are more complex, meaning that it often isn't worth it in practice
19:53:23 <Vorpal> as an experiment
19:53:40 <Bike> there are things in the nervous system that are vaguely clock-like in that they send out periodic signals independently of stimulation, but it's a pretty shallow analogy.
19:53:57 <Bike> this is important for e.g. walking without falling flat on your face and dying.

20:16:57 <CallForJudgement> I guess it is, I just said "letters"
20:17:01 <Phantom_Hoover> the spec just says 'characters', with absolutely no qualification

20:17:42 <Phantom_Hoover> but you have an advantage over the americans!
20:17:52 <CallForJudgement> yeah, I at least have an ë to play with
20:19:08 <CallForJudgement> (strange how most people deny its existence)
20:19:18 <CallForJudgement> also according to the books I originally learned the alphabet from, & is a letter
20:20:50 <boily> «éperluette», which means “and by itself, and”. it was the 27th letter.
20:21:19 <CallForJudgement> hmm, is that French for "ampersand"?
20:21:44 <CallForJudgement> (also, I remember that in Gödel, Escher, Bach, Hofstadter used ""/«»/»« quotes to distinguish English, French, and German)
20:22:17 <shachaf> «» is perfectly valid for quoting in English.
20:22:28 <boily> yes, that's the proper glyph name in French, but nobody uses it. everyone calls it «et commercial».
20:22:34 <shachaf> I've never seen »« in English, though.
20:23:30 <CallForJudgement> also, doesn't French have more than 26 letters /anyway/?
20:23:37 <CallForJudgement> e.g. é
20:25:07 <boily> they don't count as extra letters.
20:26:08 <CallForJudgement> hmm… so ä is OK in Eodermdrome, but é isn't?
20:27:33 <boily> depends in which context you use «é». In French, it is equivalent to a regular «e» (or è, ê and ë for that matter), just with a small pixelly smudge over it.

21:14:31 <oerjan> @tell Sgeo <Sgeo> Is there a name for those monads which are implementable even if bind can call its continuation at most 1 time? <-- i don't know but the STMonadTrans package refers to those without a name.
21:14:31 <lambdabot> Consider it noted.
21:14:35 <shachaf> I.e. a monotonic function.
21:14:40 <shachaf> (Monotonically increasing.)
21:15:26 <oerjan> @tell Sgeo or well, i assume it's essentially the same.
21:15:26 <lambdabot> Consider it noted.
21:19:15 <ion> shachaf: So… am i supposed to be able to make one in general?
21:19:26 <shachaf> What do you mean by "make"?
21:19:53 <shachaf> Let's say we have the poset category N of natural numbers.
21:19:59 <ion> I thought the exercise was to define F₁. So far we only have “type signatures”.
21:20:09 <shachaf> Oh.
21:20:35 <shachaf> Well, there's at most one arrow between the object F A and F B.
21:20:42 <shachaf> So you just have to show that it exists.
21:22:42 <ion> I’m not sure how to do that.
21:24:11 <shachaf> Well, take any monotonic function from N to N, for example.
21:24:34 <shachaf> You have a "functor" that maps an object x to the object x+1.
21:24:46 <shachaf> And if x≤y, then x+1≤y+1
21:24:51 <ion> yeah
21:25:53 <shachaf> Maybe I don't understand what you mean.
21:28:17 <shachaf> The goal was adjunctions or something like that, right?
21:29:19 <ion> I had the false impression that i should find a general definition of F₁ for any F : C → D, but i suppose the definition depends on the specific C and D.
21:29:45 <shachaf> Oh, I see.
21:30:01 <shachaf> Well, we have the definition of a functor, which is F₀ and F₁ which follow some laws.
21:30:45 <shachaf> (The laws are trivial when you're talking about posets, by the way.)
21:31:37 <shachaf> But when you're specifying some particular functor, you give a specific definition of F₁.
21:31:50 <ion> F₁ id = id; F₁ f ∘ F₁ g = F₁ (f ∘ g); anything else?
21:32:11 <shachaf> Those are the laws.
21:32:16 <ion> aye
21:32:47 <shachaf> Well there's a "type law" of sorts, which is that if f : A -> B then F₁ F : F₀ A -> F₀ B
21:33:08 <shachaf> (Usually people don't bother writing F₀ and F₁, just F. Or, in Haskell, they write fmap instead of F₁.)

21:34:32 <CallForJudgement> okoko
21:35:47 * oerjan wonders what those empty squares are
21:35:53 <oklopol> so if i have two say minimal compact dynamical systems X and Y, is there a name for the following: for any morphism \phi : X \times Y \to X, there's a function \psi : X \to X such that \phi(x, y) = \psi(x) for all x, y
21:36:23 <oerjan> what's a morphism
21:36:32 <oklopol> continuous function that commutes with the dynamics
21:36:52 <CallForJudgement> oh, for a moment I thought oerjan was asking what morphisms are in general
21:36:59 <CallForJudgement> and got really confused, because I expected him to know
21:37:05 <oerjan> you'd think

22:22:42 <kmc> does playing mölkky count as doing things or no
22:22:59 <Phantom_Hoover> kmc, it has a long-ish transaction delay or something?
22:23:04 <kmc> yeah
22:23:09 <kmc> a lot of physical merchants seem to not care though
22:23:13 <shachaf> tricky question
22:23:18 <shachaf> imo i don't care
22:23:48 <kmc> maybe they use a transaction processor that converts BTC immediately into bilderberg conspiracy fiat currency, and guarantees them against fraud (like cc processors do)
22:24:07 <Phantom_Hoover> what's the risk again
22:24:27 <Phantom_Hoover> you buy a croissant, eat it, then cancel the transaction before it goes through>
22:24:45 <olsner> going via "bilderberg conspiracy fiat currency" sounds quite reliable
22:25:14 <Phantom_Hoover> btw on the topic of the bilderbergs i would like to once again recommend THEM: adventures with extremists
22:25:55 <olsner> and are you sure they guarantee *against* fraud, rather than e.g. guaranteeing fraud? (I also idly wonder which one of those is more likely to give your money back)
22:26:06 <kmc> Phantom_Hoover: the risk is double spend
22:26:21 <kmc> cancel i guess would mean you double spend also by sending it to yrself
22:27:18 <Phantom_Hoover> so what, you override the earlier transaction with a second one that sends the money elsewhere?
22:27:56 <Fiora> I think the jist is you send two transactions out at once, and hope the other one gets included in the block chain?
22:28:24 <olsner> let me tell you exactly how it works
22:28:54 <Phantom_Hoover> i think i get it now
22:29:09 <kmc> or maybe you dont care which one gets included
22:29:12 <kmc> but you got two things
22:29:16 <kmc> for the price of one
22:29:30 <Fiora> I don't think a miner will accept two transactions coming from the same money?
22:29:30 <Phantom_Hoover> yeah
22:29:32 <Fiora> like, they'll reject it
22:29:34 <Phantom_Hoover> sure
22:29:39 <Phantom_Hoover> but you still have two croissants
22:29:45 <Fiora> ohhhh XD
22:31:08 <kmc> so merkhants are advised to wait for the netwrk to agree on the transxn
22:31:35 <kmc> which is not a discrete thing but the longer you wait, the less likely it will change its mind
22:31:59 <kmc> (it is discrete in units of blocks, which take avg 10 min to make)
22:32:29 <kmc> but most people dont wanna wait 10 min for a croissont much less 30
22:32:38 <kmc> so your btc bakery must take this risk
22:32:43 <kmc> or pay someone else to assume the risk
22:32:57 <kmc> in which case that third party can also run an instantaneous change to money that is actually useful to your business
22:33:21 <kmc> you know because your landlord and croissont supplier probably don't accept bitcoin (dupes of the global banker hegemony that they are)
