01:07:16 <elliott> oerjan: yes i convinced him it'd be ok
01:08:12 <oerjan> elliott: yes but you played around with a lot of env stuff, because he said something about only alphanums, which apparently isn't true
01:08:22 <oerjan> you can just use absolute paths
01:09:06 <elliott> i have no idea wtf you are talking about

01:50:17 <HackEgo> robocop: ASCII English text, with very long lines
01:51:00 <ais523> it's better in some places
01:51:19 <ais523> like, my turtles are correctly grouped close to each other
01:51:25 <HackEgo> http://codu.org/projects/hackbot/fshg/index.cgi/raw-file/tip/robocop
01:51:32 <ais523> but space_hotel is in there too and it works entirely differently
01:52:00 <oerjan> i assume that's what they call json
01:53:18 <oerjan> hagb4rd: in any case you can use `url instead of paste when the file is already in HackEgo; paste doesn't do anything other than making a copy and giving the result of url on that
01:53:43 <hagb4rd> so the first command worked?
01:54:13 <hagb4rd> how is it named robocop anyway?
01:55:18 <oerjan> hagb4rd: i just used mv
01:55:36 <hagb4rd> (or to put it this way: where do i find the result of `fetch..)
01:55:47 <oerjan> `fetch gave it a long name containing everything after the last / in the url
01:56:19 <oerjan> and that's what HackEgo gave after the -> in the `fetch response
01:56:21 <shachaf> oerjan: what's the verdict on free monads
01:56:58 <oerjan> shachaf: free monads are cool, they feel more reified somehow
01:57:19 <hagb4rd> could we have an alias for that command taking 1 argument passed as query string? do we have any conventions on creating such aliases?
01:57:31 <shachaf> oerjan: what about cofree comonads
01:58:04 <shachaf> oerjan: Cofree is just like Free except it uses (,) instead of Either.
01:58:11 <oerjan> hagb4rd: `fetch is a builtin command which can only be used alone
01:58:19 <shachaf> So Cofree f a = (a, f (a, f (a, f (...
01:58:36 <oerjan> hagb4rd: i.e. you cannot use it from within other HackEgo commands
02:00:08 <oerjan> hagb4rd: there _is_ a system for contacting a whitelist of web sites from within HackEgo commands, but it is currently broken
02:00:31 <hagb4rd> is that a convention to be satisfied`? l just would like to have some aliases binding to webservices.. which imho would be a nice method extending things ya know
02:00:50 <oerjan> hagb4rd: we used to have some
02:01:17 <oerjan> but the api's changed, so many of them broke again, and then the web proxy itself broke
02:01:28 <oerjan> only Gregor can fix it
02:02:21 <hagb4rd> `url https://www.googleapis.com/customsearch/v1?key=AIzaSyBfdt4VN9qT_Y8LAl100TBRCWAOiSTaqSY&cx=009459769908964694922:yb5esesqxmg&q=strawberry&searchType=image&fileType=jpg&imgSize=xlarge&safe=off | fetch

02:05:14 -!- WeThePeople has joined.
02:05:17 <hagb4rd> where is the output of url going to?
02:06:42 <oerjan> hagb4rd: url doesn't fetch anything, it takes a filename already existing in HackEgo and tells you where to browse it on Gregor's website
02:06:56 <oerjan> also, you cannot combine fetch with anything, i said
02:08:19 <oerjan> hagb4rd: basically url doesn't do anything other than prepending http://codu.org/projects/hackbot/fshg/index.cgi/raw-file/tip/ to its argument
02:08:59 -!- TeruFSX has joined.
02:10:15 <hagb4rd> so what is the bullshit fetch is sending to the stdout instead of the response?
02:10:35 <oerjan> basically fetch, like run and help, are builtin HackEgo commands that aren't looked up inside the sandbox. and unlike the two others fetch cannot be emulated fully.
02:10:52 <hagb4rd> can i just use wget instead?
02:11:41 <oerjan> hagb4rd: timestamp the://UrlYouGaveIt [size] -> theFileNameWhereItPutIt
02:12:06 <oerjan> wget would be restricted, and currently broken because the web proxy from inside the sandbox is broken
02:12:49 <oerjan> `wget http://www.google.com
02:12:50 <HackEgo> --2013-01-02 02:12:50-- http://www.google.com/ \ Connecting to 127.0.0.1:3128... failed: Connection refused.
02:13:25 <oerjan> iirc google.com is in the whitelist, so should work if the proxy does

02:13:55 <hagb4rd> it would be SOOOO NICE to use REST services :(
02:14:31 <oerjan> hagb4rd: you'll just have to nag Gregor to get the proxy working again
02:15:44 <hagb4rd> i'll try too, if you share my opinion on that
02:16:10 <oerjan> i think it would be nice to get some basic searches working
02:16:45 <oerjan> although lambdabot has a few relevant commands
02:17:10 <hagb4rd> and just be able to write my own services as embedded extensions
02:17:39 <hagb4rd> that was just a test in first case

02:22:10 -!- zzo38 has joined.
02:22:43 <zzo38> If I have $z=12^xy^2$ in natural numbers, then what is an algorithm to figure out x and y when given z?
02:23:35 <zzo38> (Assume y is nonzero, but x is possible to be zero.)
02:24:12 <Fiora> you mean (12^x)(y^2) or 12^(xy)^2 or ...?
02:24:43 <hagb4rd> this way we wouldn't need to have more bots joining the channel and so on.. just a clean interface as defined by a webservice.. the output goes to stdout and can be piped elsewhere.. but then we should agree on some conventions on alias/script names so we won't get lost (if we not already are)
02:25:24 <oerjan> zzo38: something like while (z % 12 == 0) { z /= 12; x++ } y = sqrt (z)
02:26:04 <zzo38> oerjan: I am not sure that works.
02:27:12 <zzo38> And it is needed one for computers that doesn't have square root and division and so on
02:27:24 <oerjan> zzo38: well ok you get _one_ solution that way, others will be given by x - 2n and y*144^n
02:28:05 <oerjan> zzo38: oh hm right there's the question of whether x or x+1 makes the remaining z a square
02:28:20 <zzo38> That is what I meant.
02:28:48 <oerjan> zzo38: but anyway starting with the above, the rest is a matter of finding the square root of the remaining part of z or 12*z
02:29:41 <Fiora> { int s = isqrt(z); if(s*s == z) {y = s; break;} if(z%12 != 0) goto fail; x++; z /= 12;
02:30:27 <oerjan> Fiora: oh hm right, that would work to halt as early as possible instead
02:30:41 <oerjan> to give the _largest_ solution for y instead
02:31:33 <oerjan> Fiora: in fact you could improve that by only testing twice, since if it doesn't become a square after dividing by 12 and wasn't one already, then it never will become one
02:34:00 <oerjan> zzo38: so if you don't have a solution with x==0 or x==1 then you don't have any at all
02:34:46 <oerjan> but if y is divisible by 12 you will get additional ones
02:35:45 <zzo38> oerjan: O, OK. I may need to change some things then, because I need to support at least up to x==2
02:36:43 <oerjan> if x==2, y==n are solutions, then x==0, y==12*n will also be

02:46:09 <Bike> what program is that
02:51:35 <oerjan> version 3.14159265358979
02:52:29 <quintopia> it is a program that outputs pi to a specified accuracy?
02:53:00 <ais523> is it TeX who uses successive approximations of pi as version numbers?
02:53:14 <zzo38> Yes, TeX uses that.
02:53:26 <zzo38> I currently have TeX version 3.1415926.
02:53:31 <shachaf> zzo38: What does TeXnicard use?
02:53:44 <zzo38> When Knuth is dead, the final official version shall be updated to version $\pi$ exactly.
02:53:52 <zzo38> shachaf: Just ordinary version numbers.
02:54:05 <zzo38> METAFONT uses approximations of the base of natural logarithms.
02:54:26 <shachaf> I should write a program whose version number approximates 2.
02:55:01 <zzo38> quintopia: It is called e, yes.
02:55:24 <shachaf> monqy: what's the verdict on free monads
02:55:51 <zzo38> Penrose uses upright rather than italic "e" for the base of natural logarithms and I agree with him; so it would be ${\rm e}$ in TeX.
02:55:55 <ion> > (exp.exp.exp.exp) 1 :: CReal
02:56:12 <zzo38> Same with imaginary unit, and derivative operator.
02:57:24 <zzo38> However, the lowercase Greek in Computer Modern is only italic, and I am not entirely sure how I might change them to be able to work with not italic lowercase Greek as well, for pi and so on, but I might be able to try.
02:57:32 <quintopia> zzo38: then you can just say e instead of "the base of natural logarithms" because we will know what you mean AND...you don't have to type as many words!
02:58:03 <zzo38> quintopia: I can type fast.

04:38:47 <shachaf> +imapMOf_ :: (Profunctor q, Monad m) => Overloading (Indexed i) q (Accessor (Sequenced m)) s t a b -> (i -> a -> m r) -> q s (m ())
04:38:50 <shachaf> +iconcatMapOf :: Profunctor q => Overloading (Indexed i) q (Accessor [r]) s t a b -> (i -> a -> [r]) -> q s [r]
04:38:54 <shachaf> +ifindOf :: Profunctor q => Overloading (Indexed i) q (Accessor (Endo (Maybe a))) s t a b -> (i -> a -> Bool) -> q s (Maybe a)
04:38:57 <shachaf> +itoListOf :: Profunctor q => Overloading (Indexed i) q (Accessor (Endo [(i,a)])) s t a b -> q s [(i,a)]
04:39:32 <shachaf> lightquake: I'm assuming this is an "it'll get worse before it gets better" sort of thing.
04:39:37 <lightquake> I have no clue how to read those type signatures
04:39:41 * kmc screams in terror
04:39:59 <kmc> i can read them syntactically but i have no idea what all the classes and one-letter variables mean
04:40:36 <shachaf> OK, the simple version is, uh...
04:40:45 <shachaf> Well, p and q are both just (->), normally.
04:40:53 <shachaf> Overloading is this one thing.
04:41:11 -!- hagb4rd has quit (Ping timeout: 252 seconds).
04:41:13 <shachaf> type Overloading p q f s t a b = p a (f b) -> q s (f t)
04:41:31 <shachaf> OK, you know what, this is hopeless.
04:41:45 <shachaf> In edwardk's defense, he has several "simple" versions of each type signature next to the "real" version.
04:42:01 <shachaf> -- 'findOf' :: 'Traversal'' s a -> (a -> 'Bool') -> s -> 'Maybe' a
04:42:41 <shachaf> This is edwardk's "expansion" phase.
04:42:41 <kmc> that oompa loompa story is like some terrible crossover of Willy Wonka and A Clockwork Orange
04:42:53 <shachaf> Where he generalizes everything and later figures out what sticks.
04:43:38 <lightquake> the perils of a rapidly-developed library, I guess
04:43:59 <shachaf> lightquake: Do you understand lens signatures in general?
04:44:13 <shachaf> Like Applicative f => (a -> f b) -> (a,a) -> f (b,b)?
04:44:15 -!- hagb4rd has joined.
04:44:47 <lightquake> i understand that you use the functor context so that you can run it with both Identity and Const and combine a getter and a setter
04:45:20 <shachaf> Well, that signature is just like mapM for tuples, right?
04:45:22 <lambdabot> Monad m => (a -> m b) -> [a] -> m [b]
04:47:45 <shachaf> So it's like that, except with Applicative.
04:48:03 <shachaf> Now we want to generalize that in various directions.
04:48:08 <zzo38> Also seems, as if you have ((->) Bool) instead of []
04:48:23 <shachaf> lightquake: All you need is Applicative, so why require Monad?
04:48:32 <shachaf> (You can't make Const a Monad, anyway.)
04:48:40 <lightquake> right, i meant, why isn't functor enough
04:48:55 <shachaf> Functor is enough when you're traversing exactly one value.
04:48:56 <zzo38> Is mapM a functor?
04:49:06 <shachaf> But both traverses two values.
04:49:15 <shachaf> lightquake: Try to write the function. You need (<*>). :-)
04:49:22 <shachaf> both f (x,y) = (,) <$> f x <*> f y
04:49:54 <shachaf> Anyway, so one direction we can generalize this is that we want indexing.
04:50:11 <shachaf> For instance, mapMWithIndex :: (Int -> a -> f b) -> [a] -> f [b]
04:50:33 <shachaf> But that's not so great because it's not compatible with regular lenses.
04:51:10 <lightquake> obviously if f is Identity, that just turns into a plain mapWithIndex
04:51:29 <shachaf> Oh, instance Monoid m => Applicative (Const m)
04:51:49 <shachaf> Where pure _ = Const mempty; Const mf <*> Const mx = Const (mf <> mx)
04:51:57 <zzo38> shachaf: You can also make instance Monoid m => Alternative (Const m)
04:52:02 <lightquake> oh, so you wind up accumulating the result
04:52:04 <shachaf> So when you use Const, it never actually rebuilds the structure.
04:52:19 <shachaf> But you can use a monoid to decide how to accumulate, right.
04:52:35 <shachaf> > foldOf both ("hello","there")
04:52:43 <shachaf> That uses the [] monoid instance.
04:53:15 <lambdabot> Not in scope: data constructor `Add'Not in scope: data constructor `Add'
04:53:43 <shachaf> > getConst $ both (\x -> Const (Sum x)) (1, 2)
04:53:44 <zzo38> Instead of [] and Int perhaps you could make it a class of a type which can be indexable by some other type? Such as, indexable (x ->) by x
04:54:10 <shachaf> Now, the trick with indexing is a little bit of overloading.
04:55:02 <shachaf> clsas Indexable i p where ...; indexedMapM :: (Indexable Int p, Applicative f) => p a (f b) -> [a] -> f [b]
04:55:08 <shachaf> Indexing has two instances.
04:55:18 <shachaf> One of them is (->); when you use that instance, it just works without the index.
04:55:40 <shachaf> The second is newtype Index i a b = Indexed { runIndexed :: i -> a -> b }
04:56:23 <lightquake> so you have an instane Indexable Int (->) that just ignores the index
04:56:30 <zzo38> But it is a category like (Kleisli ((->) i))
04:56:56 <lightquake> presumably this is actually Indexable i (->)
04:57:05 <lightquake> then what's the instance for Indexed look like?
04:57:23 <shachaf> The class is actually class Indexable i p where indexed :: p a b -> i -> a -> b
04:57:43 <shachaf> So instance Indexable i (->) where indexed f i x = f x
04:58:18 <shachaf> That way any indexed traversal can degrade to a regular traversal.
04:59:40 <shachaf> So that's one generalization.
04:59:52 <shachaf> It turns out this "p" thing is actually pretty useful.
05:00:28 <shachaf> There's a class Profunctor p where lmap :: (a -> b) -> p b c -> p a c; rmap :: (b -> c) -> p a b -> p a c
05:00:45 <shachaf> I can explain that class further if you like. :-)
05:01:17 * elliott prefers the dimap presentation
05:01:19 <shachaf> Oh, so the way we write indexed both is both f (x,y) = (,) <$> indexed f 0 x <*> indexed f 1 y
05:01:28 <shachaf> OK, elliott has volunteered to take over.
05:02:20 <shachaf> But elliott has to explain it with dimap
05:02:34 <zzo38> Is there any relation to representable functor?
05:02:59 <shachaf> zzo38: We have a lot of (co)representable profunctors.
05:03:48 <shachaf> lightquake: OK, does that class make sense?
05:04:21 <shachaf> It's a thing which is covariant in one argument and contravariant in the other.
05:04:43 <shachaf> In a sense p a b "consumes" things of type a and "produces" things of type b
05:05:00 <shachaf> (->) is the classic example.
05:05:01 <elliott> as in given (Profunctor p) you have (Functor (p a)) for all a (but you can't express this)
05:05:07 <zzo38> I can see that (->) fits
05:05:30 <zzo38> And (->) is a category
05:05:39 <zzo38> Is it related to being a category?
05:05:41 <shachaf> Not all instances of Profunctor are categories.
05:06:02 <lightquake> so what's another instance of Profunctor?
05:06:12 <zzo38> shachaf: It is what I thought.
05:06:24 <shachaf> Also there are a bunch of others.
05:06:32 <shachaf> newtype Tagged a b = Tagged { unTagged :: b }
05:06:43 <shachaf> newtype Forget r a b = Forget { unForget :: a -> r }
05:07:01 <shachaf> newtype UpStar f a b = UpStar { unUpStar :: a -> f b }
05:07:06 <shachaf> elliott: That's what I called it at first.
05:07:27 <zzo38> Can it be made, profunctors on other categories?
05:07:47 <zzo38> UpStar is the same type as Kleisli though isn't it?
05:07:58 <shachaf> zzo38: Yes, but it's used for different things.
05:08:10 <shachaf> lightquake: Let's get to that in a moment. :-)
05:08:20 <shachaf> So you can use profunctors to make this different representation of lenses.
05:08:30 <shachaf> Instead of (a -> f b), you write p a b
05:08:39 <shachaf> With various constraints on the p
05:09:09 <shachaf> If you pick Profunctor as your constraint, what you get is an isomorphism.
05:09:33 <shachaf> Because the only way you can turn "p a b" to "p s t" (if you know almost nothing about p) is by lmapping (s -> a) and rmapping (b -> t)
05:09:42 * shachaf is probably not making sense again.
05:10:03 <zzo38> (Kleisli f) makes a category if f is a category. In what cases will it make a profunctor?
05:10:05 <lightquake> doesn't isomorphism imply that you can go back from p s t to p a b?
05:10:18 <zzo38> Is it if f is functor?
05:10:47 <shachaf> lightquake: It's saying that s ~ a and b ~ t
05:10:51 <shachaf> And it lets you go back and forth.
05:11:10 <elliott> lightquake: you can treat s = t, a = b usually
05:11:14 <lightquake> how's that follow? what if s -> a is an injection?
05:11:27 <elliott> blah :: Profunctor p => p (a,b) (a,b) -> p (b,a) (b,a)
05:11:31 <elliott> blah = lmap swap . rmap swap
05:11:31 <shachaf> Well, OK, let's put it differently:
05:11:44 <shachaf> (forall f. Profunctor f => p a b -> p s t) ~~ (s -> a, b -> t)
05:12:10 <shachaf> It's a very polymorphic function, so it knows almost nothing about which profunctor you're using.
05:12:34 <zzo38> That is strange, it is f only in constraint
05:12:56 <shachaf> Can you figure out a way to "extract" the isomorphism from that type?
05:12:59 <elliott> shachaf's p key is adjacent to his f key
05:13:02 <shachaf> Start with the (b -> t) direction.
05:13:47 <shachaf> I give you foo :: forall p. p a b -> p s t
05:13:57 <shachaf> You have to give me bar :: (b -> t)
05:14:11 <shachaf> (This means that you have to pick some specific concrete profunctor to use.)
05:15:05 <shachaf> Usually we call this function review.
05:15:22 <shachaf> Because it's the opposite of the direction of view
05:15:28 <shachaf> review :: (Tagged a b -> Tagged s t) -> b -> t
05:17:20 <shachaf> OK, next exercise: Get s -> a
05:17:49 -!- asiekierka has quit (Excess Flood).
05:17:56 -!- asiekierka has joined.
05:18:27 <elliott> retrieve s -> a from an iso in that form
05:18:38 <lightquake> oh, i thought Get was a type constructor
05:19:35 <shachaf> Oh, wait, it does have the right kind.
05:19:44 <shachaf> Try to make it a Profunctor instance. :-)
05:19:52 <zzo38> How can you have (Get s -> a) unless Get is like Initialize?
05:19:53 <elliott> Const isn't contravariant in its first argument
05:20:13 <shachaf> elliott: It's actually Constravariant
05:21:11 <shachaf> Well, as a hint, think about how you normally "get" things with (a -> f b) lenses.
05:22:31 <shachaf> Right, but how does the full signature end up looking?
05:22:53 <shachaf> How do you get (s -> a) from that?
05:23:45 -!- sebbu2 has joined.
05:24:06 -!- sebbu2 has quit (Changing host).
05:24:06 -!- sebbu2 has joined.
05:25:46 <lightquake> i don't think that's right anyway, bah. anyway it's (a -> Const a b) -> s -> Const a t
05:26:10 <shachaf> OK, now reduce it one more step?
05:26:48 -!- sebbu has quit (Ping timeout: 245 seconds).
05:27:40 <shachaf> So pretty much the same trick works for profunctors.
05:27:42 <elliott> @type \f s -> getConst (f Const s)
05:27:43 <lambdabot> ((a1 -> Const a1 b1) -> t -> Const a b) -> t -> a
05:28:26 <lightquake> so we have (forall f. Profunctor f => p a b -> p s t) and we want to get out s -> a
05:29:33 <lightquake> anyway. p = Const doesn't work because you don't get the right direction
05:31:16 <elliott> lightquake: Forget is kind of like Const
05:33:37 <lightquake> yeah, I think forget a works, since it becomes Forget a a b -> Forget a s t, which is just (a -> a) -> (s -> a)
05:34:09 <shachaf> It's pretty much the same trick.
05:34:41 <shachaf> So view f = under _Forget f id
05:34:58 <shachaf> So that's the basic idea of profunctor lenses.
05:35:14 <shachaf> You can get everything that (a -> f b) lenses give you just by picking p a b = (a -> f b)
05:36:56 <lightquake> and you can also get indexed stuff using Indexed
05:37:28 <shachaf> And you can define newtype Conidexed i a b = Coindexed { unCoindexed :: a -> (i,b) }
05:37:34 <hagb4rd> also forget about everything using a good programming language
05:37:38 <elliott> technically you need to separate the p
05:37:48 <elliott> instead of (p a b -> p s t) it becomes (p a b -> q s t) for Indexed
05:37:56 <elliott> because you don't want the (i ->) on the return side
05:38:08 <elliott> (i -> a -> f b) -> s -> f t, not (i -> a -> f b) -> i -> s -> f t
05:38:22 <shachaf> +ifindOf :: Profunctor q => Overloading (Indexed i) q (Accessor (Endo (Maybe a))) s t a b -> (i -> a -> Bool) -> q s (Maybe a)
05:38:39 <shachaf> So that becomes, uh, elliott wants to expand that for me.
05:39:15 <Sgeo> If I start really getting into Racket and writing macros, and switch back to Clojure, adjusting to the unhygienic macros might be "fun"
05:39:34 <elliott> shachaf: well, this isn't quite profunctor stuff directly
05:39:36 <Bike> the clear solution is to write the racket macro system in clojure.
05:39:42 <elliott> because you have the functor jamming stuff back up due to the "compromise" we have in lens
05:40:14 <kmc> Raclojuractorcl
05:40:14 <Sgeo> Bike, I haven't looked for myself, but I think someone did that
05:40:49 <shachaf> lightquake: In lens we use p a (f b) -> p s (f t) instead of p a b -> p s t
05:40:57 <shachaf> That gets you a different overloading:
05:41:30 <hagb4rd> sgeo: i don't believe you'll do, since you're changin paradigms quite as often as your underwear :P everyday a new adventure
05:41:46 <shachaf> Instead of, say, mapped :: p a b -> p [a] [b], which becomes just the regular map function when p = (->), we use mapped :: p a (Identity b) -> p [a] (Identity [b])
05:42:08 <shachaf> It's a bit more awkward but it gives us compatibility with the classic style of lens.
05:42:27 <elliott> (because you can just pick p = (->) and get something that fits the (a -> f b) -> s -> f t pattern directly)
05:42:34 <elliott> so they compose properly with lenses and the like
05:42:46 <elliott> instead of "lmap f . rmap g" it becomes "lmap f . rmap (fmap g)"
05:42:57 <elliott> and an iso is (Profunctor p, Functor f) => p a (f b) -> p s (f t)
05:45:05 <elliott> (Profunctor p, Indexable i p, Applicative f) => p a (f b) -> s -> f t
05:45:10 <elliott> for a traversal indexed in "i"
05:45:31 <elliott> that's just like (i -> a -> f b) -> s -> f t but it works as a plain traversal, composes properly with isomorphisms, etc.
05:46:44 * Sgeo is somewhat alarmed at all the pre-name-change code on PLaneT
05:46:44 <shachaf> But that's not enough because we want Coindexing!
05:47:14 <shachaf> So we get (Profunctor p, Indexable i p, Coindexable j q, Applicative f) => p a (f b) -> q s (f t)
05:47:25 * elliott thinks shachaf just gave up
05:48:09 <elliott> (class Coindexable u q where coindexed :: (a -> (u, b)) -> q a b)
05:48:10 <shachaf> lightquake: By the way, we haven't figured out a use for coindexing yet.
05:48:18 <elliott> (i -> a -> f b) -> s -> f t
05:48:23 <elliott> (a -> f b) -> s -> (u, f t)
05:48:35 <monqy> did you just add coindexing for fun
05:48:36 <elliott> one adds (i ->) to the p and the other (u,) to the q
05:48:46 <shachaf> elliott: Remember when you thought Coindexing was self-adjoint???????
05:48:58 <hagb4rd> it works pretty well when it comes to confusing everybody

10:10:48 <coppro> 0.26 -> 1.26 (bugfix) -> 0.27

10:21:08 <elliott> Deewiant: remember that time I asked you about whether a name was a real finnish name and stuff

10:21:19 <Jafet> <@oklopol> I wish I had this quote
10:21:27 <elliott> wow how could you not remember that vital turning point in each of our lives
10:21:44 <elliott> also they have disappeared for like months; possibly due to guilt at lying about being finnish?
10:21:49 <Deewiant> coppro: I don't know the commands and don't really care either
10:22:07 <coppro> Deewiant: you can `revert and then `addquote. How would you format it?
10:22:11 <Deewiant> elliott: Well to be honest I have a faint memory of something like that occurring but no details
10:24:11 <Deewiant> coppro: I think there's some kind of "standard" on this channel with putting two spaces between separate lines and enclosing nicks in <> but without the space; but like said I don't really care and as such I'm not sure about this either
10:25:38 <elliott> imo we must find our own standards inside our hearts and then impose them ruthlessly on others for nothing but the joy of cruelty
