00:05:00 <shachaf> elliott: Does a Lens (Either a a) a make sense?
00:05:26 <shachaf> Oh, yes.
00:05:29 <shachaf> It's called "chosen".
00:06:19 <elliott> shachaf: Traversal (a, a) a also makes sense
00:06:27 <shachaf> Hmm, choosing :: Functor f => LensLike f a b c c -> LensLike f a' b' c c -> LensLike f (Either a a') (Either b b') c c
00:06:32 <elliott> we still have pence yes
00:06:50 <shachaf> elliott: That's "both".
00:07:08 <shachaf> Except I wrote it out for some reason.
00:10:32 <elliott> Oh, so it is.

00:17:58 <shachaf> _|_ is terrible. That's why I use ⊥.
00:18:08 <shachaf> elliott: Anyway remember how I kept getting confused about semantics of that sort of thing?

02:16:23 <kmc> it's like ctypes for shell

04:45:30 * pikhq did not realize those "see no evil, hear no evil, speak no evil" monkeys were the result of a Japanese *pun*.
04:47:02 <pikhq> "See no, hear no, speak no" in moderately archaic Japanese is "mizaru, kikazaru, iwazaru". And "seeing monkey, hearing monkey, speaking monkey" can be "mizaru, kikazaru, iwazaru".

13:03:29 <fizzie> "Quiet" is quite often used in terms of command line arguments.
13:03:36 <fizzie> But a "quiet language" sounds a bit silly.
13:03:45 <ion> concise?

13:04:15 <ion> laconic?
13:04:18 <fizzie> (Though possibly only when spelled uppercase like that.)
13:04:20 <Arc_Koen> "terse" seems to imply you're using words, but no more than the right amount

14:45:33 -!- epicmonkey has quit (Remote host closed the connection).
14:45:39 <tswett> You see, there's this runaway trolley.
14:45:44 -!- epicmonkey has joined.
14:45:59 <tswett> On the track in front of a trolley, there are five oak branches. If the trolley hits the oak branches, the branches will be destroyed.
14:46:38 <tswett> However, there is a footbridge above the track that has one large oak branch on it. You can push the branch off the bridge and onto the track.
14:47:29 <tswett> If you do, the one large oak branch will be destroyed, but it will stop the trolley, causing the other five oak branches to remain intact.
14:47:34 <tswett> Is it morally acceptable to do this?
14:49:07 <elliott> is the joke that the oak branches are people
14:49:23 <tswett> It's not a joke.

16:09:18 <oerjan> ah i've been having an opportunity to watch tv recently, which has finally brought me in contact with that series.
16:09:40 <atriq> Thoughts on it?
16:09:42 <oerjan> i have far too many similarities to Sheldon. not the lack of empathy, but otherwise...
16:09:53 <atriq> So do we all
16:09:53 <oerjan> well i laughed.
16:10:51 <oerjan> does "all" refer to just this channel, or most people...
16:11:04 <kmc> that show is so bad
16:12:24 <oerjan> kmc: sarcasm?
16:12:40 <kmc> no
16:12:44 <kmc> Big Bang Theory is really bad
16:13:17 <elliott> kmc++
16:14:09 <kmc> hey let's make an unfunny laugh track multicamera sitcom except we base it around nerd stereotypes instead of racial stereotypes and gay people stereotypes and NOW NERDS LOVE US
16:14:26 <nortti> basicaly yes
16:14:30 <kmc> nerds don't act that way
16:14:32 <kmc> people don't act that way
16:14:53 <kmc> that type of sitcom is really just a vehicle for delivering one liner jokes
16:15:05 <kmc> i could just watch standup comedy instead and be infinitely less annoyed
16:15:24 <oerjan> but are your reasons for hating it themselves nerdy? *ducks*
16:15:37 <kmc> probably
16:15:38 <elliott> kmc: it wouldn't even be so objectionable if it was, you know, actually funny
16:15:39 <kmc> who gives a shit
16:16:26 <kmc> i have watched a fair amount of BBT and also a fair amount of two and a half men (same creater)
16:16:34 <kmc> and then one day i was just like "why?????"
16:16:36 <oerjan> next you'll tell me you also hate phineas & ferb, the other show i've just started watching
16:16:36 <kmc> and quit
16:16:50 <kmc> i've never seen phineas & ferb, and i have no opinion on it
16:17:00 <kmc> i mean if you enjoy BBT, then go ahead and watch it, don't let me tell you not to like something
16:17:23 <kmc> it's not like i didn't ever laugh while i was watching it
16:18:24 <oerjan> i did get a glimpse of two and a half men too, and i didn't like that
16:20:27 <atriq> Trivia: Big Bang Theory doesn't actually have a laugh track
16:21:12 <elliott> clearly we have differing definitions of laugh track.
16:21:13 <elliott> or laugh. or track.
16:21:29 <atriq> It's filmed in front of a live audience
16:21:35 <kmc> yeah
16:21:43 <kmc> these things are technically different, but you take my meaning
16:21:47 <elliott> that's still a laugh track
16:21:59 <elliott> it exists for the purpose of putting laughs in because that makes people laugh more
16:22:10 <kmc> either way it completely changes the pacing of the show
16:22:14 <elliott> and i suspect most "live audiences" are directed when to laugh, or at least mixed misleadingly
16:22:32 <kmc> the characters will say something and then just stand there for 1-2 seconds while people laugh
16:22:36 <elliott> there are good sitcoms with laugh tracks
16:22:46 <elliott> IT Crowd, for example
16:22:54 <elliott> it probably wouldn't lose much if it didn't have the laugh track though
16:23:00 <elliott> but it isn't annoying imo
16:23:01 <kmc> That Mitchell and Webb Look has a laugh track and is very good, but it's sketch comedy
16:23:27 <kmc> i think Peep Show doesn't
16:23:31 <kmc> can't recall
16:25:11 <Robdgreat> I don't think so
16:25:26 <Robdgreat> though it's amazing how little attention I pay to things like that

18:37:30 <tswett> I'm pondering a notion of "bigness" of numbers. Let's define the number 3 has having a bigness of 1, 3 -> 3 as having a bigness of 2, 3 -> 3 -> 3 as having a bigness of 3, 3 -> 3 -> 3 -> 3 as having a bigness of 4, and so on.
18:37:53 <FreeFull> Using conway's arrows?
18:37:56 <tswett> Yep.
18:38:00 <tswett> Graham's number must then have a bigness between 3 and 4. So what should its bigness be, exactly?
18:38:30 <FreeFull> How big is A(6,3)
18:39:15 <tswett> Well, that's the same as... 2 -> 6 -> 4, I think? So it looks like its bigness is around 3.
18:40:37 <tswett> It's 2 ^^^^ 6, or 2 ^^^ 2 ^^^ 2 ^^^ 2 ^^^ 2 ^^^ 2. I'm reasonably sure its bigness is greater than 3, then, since 3 -> 3 -> 3 is only 3 ^^^ 3.

18:51:23 <elliott> @tell ais523 tavern isn't run by the devs
18:51:24 <lambdabot> Consider it noted.
18:51:28 <tswett> TREE(3) could very well have a very large bigness.
18:53:17 <olsner> what happened to oerjan?
18:54:35 <fizzie> A very long supper, based on the quit message.
18:54:53 <fizzie> Actually I suppose it's been only two hours so far, that's not so long.
19:00:24 <pikhq> Gregor: Huh.
19:16:22 * tswett ponders what's between 3 -> 3 -> 3 -> 2 and 3 -> 3 -> 3 -> 3.
19:16:54 <tswett> What's a simple number that's subjectively midway between them?
19:17:02 * copumpkin wonders what the first decimal digit of TREE(3) is
19:17:12 <tswett> The way that 3 -> 3 -> 3 -> 2 is subjectively midway between 3 -> 3 -> 3 -> 3 and 3 -> 3 -> 3 -> 1.
19:19:00 <copumpkin> or even the first digit of graham's number
19:19:50 <coppro> tsethat's a silly definition
19:19:59 <coppro> *tswett: that's a silly definition
19:20:16 <tswett> It's not a definition at all; it's an example.
19:20:20 <coppro> of bigness
19:20:21 <coppro> 4 has bigness 2 and 1 by your def
19:20:39 <tswett> Huh?
19:20:45 <coppro> 4 = 4
19:20:47 <coppro> 4 = 2 -> 2
19:21:21 <tswett> You're overgeneralizing. This definition of bigness is only for numbers of the form 3 -> 3 -> ... -> 3 -> 3.
19:21:56 <FreeFull> tswett: A(100,100)?
19:22:27 <coppro> then Graham's number has no bigness
19:22:34 <tswett> FreeFull: Wikipedia says that's (2 -> 103 -> 98) - 3.
19:22:39 <tswett> Well, its bigness is, so far, undefined.
19:25:49 -!- augur has quit (Remote host closed the connection).
19:26:10 <tswett> Lessee. If you define E(n) as 3 -> 3 -> (n) -> 2, then 3 -> 3 -> 3 -> 2 is E(3) whereas 3 -> 3 -> 3 -> 3 is... E(E(27)), I guess. And 27 = E(1).
19:26:29 <tswett> What's subjectively midway between E(3) and E(E(E(1)))? I dunno. E(E(2))?

19:31:26 <tswett> If I could just think of a function that takes 3 to 3 -> 3, 3 -> 3 to 3 -> 3 -> 3, 3 -> 3 -> 3 to 3 -> 3 -> 3 -> 3, and so on...
19:31:45 -!- Nisstyre has joined.
19:36:44 <FreeFull> f(x) = x -> 3
19:37:09 <FreeFull> Unless you mean 3 -> 3 becomes 3 -> 3 -> 3 -> 3 -> 3
19:52:26 <fizzie> FreeFull: That's not how -> works.
19:53:24 <fizzie> See http://en.wikipedia.org/wiki/Conway_chained_arrow_notation#Interpretation
19:56:46 <fizzie> 2 -> 3 -> 2 is not 2 -> (3 -> 2), nor is it (2 -> 3) -> 2.
19:59:08 <Bike> fast growing function, then.

22:41:10 <tswett> Hm. Conway's chained arrow notation makes sense for ordinal numbers.
22:42:28 <tswett> Let w = omega. Then w -> w is simply w^w. w -> w -> w is... I guess we have to say it's the limit of w -> w -> n for natural numbers n.
22:42:47 <coppro> tswett: any extension of arithmetic does, pretty much
22:43:34 -!- Phantom__Hoover has quit (Ping timeout: 240 seconds).
22:44:50 <tswett> Which... let's assume that it still corresponds to up-arrow notation; that means w -> w -> w is the limit of w ^(n) w for natural numbers n, where ^(n) is n up-arrows.
22:46:53 <tswett> w ^(2) w is epsilon_0, isn't it? Then I have no idea what w ^(3) w is, and w ^(w) w must be really, really big.
