00:00:25 <tswett> z(a,b) is defined as the smallest ordinal number c such that c > a, c > b, and c is not the value of z for any smaller a, or for the same a with a smaller b.
00:00:33 <oerjan> tswett: i think that should be the Tardigrade hth
00:00:56 <tswett> oerjan: I think I agree. th
00:01:07 <tswett> Now, it's not obvious to me that that function is well-defined.
00:01:57 <tswett> z(0,b) is simply the successor of b, and it's obvious that the successor function "misses enough" ordinal numbers.
00:02:25 <tswett> (That is: the collection of ordinal numbers which are not in the image of the successor function is isomorphic to the collection of all ordinal numbers.)
00:02:30 <oerjan> tswett: didn't we discuss this earlier
00:02:41 <tswett> Maybe.
00:02:45 <oerjan> i recall it almost melted my brain
00:02:52 <oerjan> but that somehow, there were enough gaps
00:03:15 <tswett> Yeah. So, why are there always enough gaps?
00:05:33 <hppavilion[1]> Fuzzy Bag Typing
00:07:22 <tswett> Wait, I'm starting to remember, I think.
00:07:31 <tswett> Suppose you have some function f on the ordinal numbers such that for all x, f(x) > x.
00:08:11 <tswett> Then you can start at any ordinal number and iterate f on it. This will give you an infinite increasing sequence of ordinal numbers. Then take the limit of that sequence.
00:08:41 <tswett> That number that you just got, that limit, can't be in the image of f.
00:09:05 <oerjan> f needs to be increasing
00:09:19 <tswett> Does it?
00:10:12 <tswett> Yeah, I guess it does.
00:10:31 <tswett> The infinite sequence that you get is increasing even if f is not increasing. But, uh...
00:10:53 <oerjan> maybe you can take supremums of f(0)...f(x)
00:11:05 <tswett> My train of thought fell down a mine shaft.
00:11:12 <tswett> (MTOTFDAMS)
00:11:33 <oerjan> hi, welcome to the mine of brain liquification
00:11:49 <tswett> So, this makes z well-defined.
00:12:08 <tswett> Now, it happens that the entirety of z has "enough gaps", too.
00:12:31 <tswett> Why?

00:39:14 <quintopia> hello
00:41:24 <hppavilion[1]> adu: One data point is not enought to turn a hypothesis into a theory
00:41:54 <adu> hppavilion[1]: tell that to my success story!
00:42:28 <hppavilion[1]> adu: Are you a young earth creationist?
00:46:59 <oerjan> <hppavilion[1]> Pokadots that will rip you to shreds given the chance <-- *polkadots hth
00:47:50 <hppavilion[1]> oerjan: No.
00:48:02 <oerjan> Yes.
00:50:16 <adu> hppavilion[1]: I'm going to pretend I know what you're talking about
00:51:05 <hppavilion[1]> adu: You haven't heard of young earth creationists?
00:51:17 <adu> hppavilion[1]: I've heard of creationists
00:51:19 <hppavilion[1]> adu: They're the guys who think the universe is 6000 years old, same as the earth
00:51:32 <hppavilion[1]> Created by gaaaaaaaaaaaawd 6000 years ago
00:51:35 <adu> those are people who believe the universe is 6000 years old
00:51:47 <adu> I'm not sure what "young earth" means in that context
00:52:11 <hppavilion[1]> adu: There are two types- old earth and young earth
00:52:31 <hppavilion[1]> Old earth at least try to mix some basic science- the things we know for a fact to be true- into their beliefs
00:52:33 <adu> how do they explain older stuff?
00:52:51 <hppavilion[1]> adu: God created everything to look older than it is
00:52:52 <ais523> adu: "young earth creationists" are the subset of creationists who have a specific time in mind for the creation of the earth that's on a relatively small timescale, normally somewhere around 4000 BC
00:53:06 <hppavilion[1]> Young earthers throw science out the window
00:53:23 <adu> hppavilion[1]: I believe that the universe is older than anything in the universe
00:53:29 <hppavilion[1]> adu: They think we can see stars >6000 light-years away because god created the universe with everything already here
00:53:38 <hppavilion[1]> (everything = light)
00:53:48 <adu> hppavilion[1]: I also have a very strict definition of "universe" and "spacetime"
00:54:49 <adu> hppavilion[1]: a "spacetime" is all that we will ever know: 3D space + time, but the "universe" is all that exists, and all this popsci mumbo jumbo about "paralell universes" is, in my dictionary, talking about "parallell" spacetimes, not universes
00:55:05 <hppavilion[1]> It's funny that wikipedia says "Fictional superhero" instead of just "superhero"
00:55:28 <hppavilion[1]> adu: I think you mean the multiverse hth
00:55:31 <adu> so my dictionary does not contain the word "multiverse", since obviously, it is a synonym for "universe"
00:55:40 <adu> hppavilion[1]: lol, I hate you for that
00:56:11 <hppavilion[1]> adu: Usually, the Universe only covers things we can get to without a particle accelerator from here to Alpha Centauri
00:56:24 <adu> hppavilion[1]: that's called a Spacetime, sir
00:57:10 <hppavilion[1]> adu: No, it's the universe
00:57:33 <adu> hppavilion[1]: no, it's a spacetime, which most people inaccurately equate with the universe
00:58:23 <adu> The Universe, is by definition, all that exists, if multiple spacetimes exist, then they exist within The Universe, by definition
00:58:30 <adu> this is just pure logic, it's not an opinion
01:06:00 <oerjan> @tell <b_jonas> huh... but I thought I reverted something else <-- you tried to `revert a command that didn't actually change anything hth

01:06:09 <oerjan> @tell b_jonas <b_jonas> huh... but I thought I reverted something else <-- you tried to `revert a command that didn't actually change anything hth

01:10:09 <oerjan> shachaf: are you an extremely young earth creationist
01:10:52 <shachaf> oerjan: perhaps i'm a veetan
01:11:29 <adu> oerjan: shachaf didn't deny it
01:11:53 <shachaf> i'm not all that young anymore
01:12:13 <shachaf> but i'm certainly an earth creationist
01:12:18 <shachaf> what other sort of creationist would i be

01:35:33 <adu> ais523: that sounds like a hashtag
01:39:19 <hppavilion[1]> If call/cc is GOTO, what's COMEFROM?
01:39:50 <hppavilion[1]> adu: Do you know?
01:40:19 <shachaf> call/cc isn't GOTO
01:41:03 <hppavilion[1]> shachaf: It's the functional equivalent, according to wikipedia
01:42:52 <adu> hppavilion[1]: do you mean try0catch?
01:43:19 <hppavilion[1]> adu: For what? comefrom?
01:43:32 <hppavilion[1]> Or as the functional GOTO
01:43:35 <adu> hppavilion[1]: call/cc is CAMEFROM, cc is GOTO
01:43:54 <adu> hppavilion[1]: or perhaps you mean (dynamic-wind)
01:44:06 <hppavilion[1]> adu: Oooh, what's that?
01:44:14 <adu> hppavilion[1]: it's like try-catch
01:44:36 <adu> hppavilion[1]: it ensures that it's 3 arguments are all executed, in order, regardless of exceptions thrown
01:45:16 <adu> (dynamic-wind a b c) will execute c, even if a and b throw exceptions
01:45:27 <hppavilion[1]> What happens if the function you pass to a call/cc is another continuation?
01:45:27 <oerjan> <hppavilion[1]> My left arrow key seems to have stopped working <-- it's spreading!
01:45:27 <adu> or call a "cc" from somewhere else
01:45:48 <adu> hppavilion[1]: then the world starts to explode
01:46:04 <hppavilion[1]> adu: But then you call a continuation and it stops exploding
01:46:19 <adu> ((call/cc call/cc) (call/cc call/cc)) is when the world explodes
01:46:32 <hppavilion[1]> Oh, right
01:47:40 <hppavilion[1]> adu: In esolisp, should I include call/em instead of call/cc as primitives?
01:47:50 -!- Phantom_Hoover has quit (Read error: Connection reset by peer).
01:48:20 <adu> hppavilion[1]: my personal opinion is that all you need is call/ec, which is like call/cc, but the continuation cannot escape the lexical scope of call/ec
01:48:35 <hppavilion[1]> adu: And what does ec stand for?
01:49:53 <adu> hppavilion[1]: scratch that, "dynamic extent", not "lexical scope"
01:50:19 <hppavilion[1]> adu: You're much smarter than me. Can you help me with #esoteric lisp?
01:50:31 <hppavilion[1]> Passively, if you prefer
01:50:34 <adu> hppavilion[1]: as if lisp isn't esoteric enough ;)
01:50:50 <hppavilion[1]> adu: That's the tagline ;)
01:51:45 <hppavilion[1]> adu: That works too
01:51:47 <adu> for example, I once deployed an update to every server with an extra comma, that caused all of our servers to crash, repeatedly
01:52:11 <adu> I think I deleted the comma about 4 hours later

01:59:53 <adu> like now scheme is at R7RS
02:00:09 <adu> that was kind of like goto

02:01:07 <hppavilion[1]> MY EEEEEEEEEEEEEEEYES
02:01:25 <hppavilion[1]> adu: Not only is it weird and confusing with an IMproper implementation
02:01:38 <hppavilion[1]> adu: I'm also reacting to plain-font code
02:02:22 <hppavilion[1]> adu: If call/cc is functional GOTO, what's functional IF?
02:02:35 <adu> hppavilion[1]: arc if is probably the most obscure
02:02:37 <hppavilion[1]> Not the construct named IF necessarily- the one that evaluates one of its arguments based on another
02:02:42 <adu> lisp and schem use 3-argument if
02:03:09 <hppavilion[1]> adu: I'm going for what you get if you use call/cc like JMP in compiled code; what does IF look like then?
02:03:10 <adu> arc if is equivalent to lisp and scheme (cond), so (if a b c d e) actually means (if a b (if c d e))
02:03:25 <hppavilion[1]> Wat
02:03:42 <hppavilion[1]> adu: So conditional call/cc
02:03:47 <adu> hppavilion[1]: no, just if
02:03:57 <adu> it's like the classic if-elseif-else
02:04:11 <adu> hppavilion[1]: conditional on what?
02:04:15 <hppavilion[1]> (call-with-current-continuation-if-<cond> cond func else)
02:04:34 <hppavilion[1]> adu: Basically, it's the functional equivalent of low-level JMP
02:05:05 <hppavilion[1]> adu: And I'm wondering what happens if we exactly transcribe the implementation of IF-THEN to JMPs into functional programming
02:05:11 <hppavilion[1]> Do you get what I'm trying to say?
02:05:13 <adu> hppavilion[1]: oh, you want delimited-continuations
02:05:18 <hppavilion[1]> adu: Is that it?
02:07:09 <hppavilion[1]> adu: I'm not sure you understand, but odds are it's me who isn't understanding
02:07:30 <adu> hppavilion[1]: I think one of the issues with goto's in scheme is that all previous attempts involve going where you've gone before
02:07:59 <adu> if you want to jump to a place *after* everything you've done, then you probably just need to invent a name for it
02:08:09 <hppavilion[1]> adu: Ah, yes, that
02:08:55 <hppavilion[1]> adu: What I'm trying to say is this
02:09:05 <hppavilion[1]> adu: You know how call/cc is sort of like a JMP?
02:10:48 <adu> as opposed to CALL, which manipulates the stack
02:11:31 <hppavilion[1]> adu: OK, and you know how if-then in imperative languages is implementable in terms of JMP
02:11:47 <hppavilion[1]> Well, conditional JMP
02:12:11 <hppavilion[1]> adu: What happens if you implement if-then the same way, but in terms of conditional call/cc (and functionalizing everything)?
02:12:24 <hppavilion[1]> adu: Is it just (if x y z), or does it make something new?
02:12:47 <adu> (call/cc (lambda (return) (if x (return y) (return z))))
02:13:34 <hppavilion[1]> adu: So it's exactly the same then?
02:13:35 <hppavilion[1]> OK
02:13:37 <adu> hppavilion[1]: there are more possibilities, like you can return y in places that are not technically tail-calls
02:16:24 <hppavilion[1]> Ah
02:16:25 <adu> like without call/cc, then (begin a b c d e ... z) would always return z
02:16:26 <adu> but with call/cc, then (call/cc ... (begin a b c (return y) ... z)) would return y instead of z, even though z is a tail call
02:18:29 <adu> hppavilion[1]: so really call/cc should be called convert-return-into-a-function

08:18:24 <b_jonas> ah yes, great QC comic. Jeph does these sorts of montages great.
08:18:40 <b_jonas> He did them multiple times.
08:24:49 <b_jonas> Huh? The second Conspiracy set (announced a few weeks ago but more details given yesterday) will be focused on multiplayer games after a draft with cards affecting draft?
08:28:40 <shachaf> Isn't that also true of the first Conspiracy set?
08:28:47 <shachaf> I didn't know there'd be a second one.
08:30:21 <b_jonas> shachaf: the draft part is true, but as far as I know, the multiplayer isn't. maybe I just didn't pay much attention.
08:30:30 <b_jonas> shachaf: and the second one isn't released yet.
08:30:33 <shachaf> Conspiracy was designed for multiplayer games.
08:30:40 <shachaf> They had all those voting cards.
08:30:41 <b_jonas> Um, ok.
08:30:57 <b_jonas> In that case I just didn't pay attention to that set.

19:56:42 <Vorpal> hppavilion[2]: <Vorpal> <Vorpal> hppavilion[1]: Also I never ran into sequent calculus before, but to me it appears to be a rather complicated way of expressing things. Does it have additional power compared to classic logic? Or what is the big deal?
19:56:45 <hppavilion[2]> Oh
19:56:48 <Vorpal> That one
19:56:55 <hppavilion[2]> Vorpal: I'm not sure; I don't understand it yet
19:57:01 <Vorpal> fair enough
19:57:01 <hppavilion[2]> Vorpal: I think it's just different, and a bit eso
19:57:18 <Vorpal> hppavilion[2]: it just looks like a more complicated way to express implication
19:57:22 <hppavilion[2]> Vorpal: It's a generalization of natural deduction, which reminds me of Horn Clauses
19:57:52 <Vorpal> instead of (P and Q) -> (X or Y) you write P, Q |- X, Y
19:57:59 <Vorpal> Or have I missed something
19:58:01 <hppavilion[2]> Yeah, that's what I'm getting
19:58:12 <hppavilion[2]> Vorpal: I think the point is that you can ONLY do stuff in that format
19:58:18 <Vorpal> Ah
19:58:21 <hppavilion[2]> And that format provides you with different ways of looking at things
19:58:23 <hppavilion[2]> Like cuts
19:58:30 <Vorpal> cuts as in?
19:58:35 <hppavilion[2]> Vorpal: Let me type it out
19:58:46 -!- ais523 has joined.
19:59:01 <ais523> oh wow, today's roborosewater card (Seating Tute) is hilarious
19:59:14 <hppavilion[2]> If you have A, B |- q and C |- p, A, it looks like you can syllogize it into C, B |- q, p
19:59:44 <hppavilion[2]> Vorpal: That's a cut ^
19:59:48 <hppavilion[2]> I think
19:59:51 <Vorpal> um...
19:59:55 <ais523> hppavilion[2]: no it isn't
20:00:08 <ais523> also, you seem to have an extra element today
20:00:18 <ais523> cut is A |- B and B |- C syllogizing into A |- C
20:00:43 <ais523> something that mathematical logicians like doing is proving that it's admissible (i.e. any given cut, you can replicate using other rules of the logic)
20:01:00 <hppavilion[2]> ais523: OK, good. The world makes sense again.
20:01:33 <hppavilion[2]> ais523: I'm hppavilion[2] when hppavilion[1] is taken, usually when I get off the computer then get back on too soon
20:02:17 <ais523> I know it's an alternate nick
20:03:21 <Vorpal> <ais523> cut is A |- B and B |- C syllogizing into A |- C <-- isn't this just A->B, B->C giving you A->C.
20:03:34 <Vorpal> in classical implication ways of writing it
20:03:55 <ais523> Vorpal: well treating |- as -> is a common "intuitive" way to think about mathematical logic
20:04:09 <ais523> but they aren't the same operator and if you want to use them the same way, you have to prove it

20:06:58 <b_jonas> ais523: yes, they aren't even of the same type. and the Gödel completeness theorem for first-order logic is one of the most interesting theorems of logic, both for the result itself and because of its two proofs.
20:06:59 <hppavilion[2]> What's a good event-driven model of computation?
20:07:09 <Vorpal> ais523: hm, fair enough
20:07:11 <ais523> hppavilion[2]: pi calculus
20:07:13 <hppavilion[2]> And is there a logic it corresponds to?
20:07:20 <hppavilion[2]> ais523: OK, I'll look into that
20:07:20 <b_jonas> hppavilion[2]: wait, where's your [1]?

20:07:57 <ais523> gah
20:08:01 <Vorpal> * ais523 has quit ()
20:08:04 <b_jonas> ais523: Client Quit (which means your client sent an explicit QUIT
20:08:12 <ais523> Konversation's just randomly deciding my network is down
20:08:15 <ais523> with no evidence for this
20:08:18 <ais523> and quitting in response
20:08:34 <b_jonas> but your connection didn't live for long enough to send the quit message to us)
20:08:56 <b_jonas> ais523: I think it's sometimes the server. When an irc server randomly decides to quit you, it invents fake reasons for why he did so.
20:09:09 <ais523> b_jonas: no, I'm pretty sure it's the client
20:09:22 <ais523> based on the messages it's printing
20:09:28 <b_jonas> ok, that's possible too

20:09:52 <ais523> [20:09] [Info] Network is down, will reconnect automatically when it is back up.
20:10:07 <b_jonas> ais523: I think for me, it's mostly the network, because I get similar disconnections to non-irc stuff sometimes
20:10:13 <ais523> and the "network is down" is normally based on the network up/down status from NetworkManager
20:10:18 <b_jonas> the network connection from the machine that is
20:10:24 <ais523> but then, why would you send a quit if the network is down?
20:10:27 <ais523> you wouldn't expect it to be received

20:10:34 -!- ais523 has quit (Client Quit).
20:11:14 -!- ais523 has joined.
20:11:29 <b_jonas> ais523: the tcp socket can breaks in one direction, so the QUIT you send can get through even if what the server says can't get to you. eventually there's a timeout because of the one-directional break, but the QUIT still gets through.
20:11:39 <ais523> I restarted my client in case it helped
20:16:27 <b_jonas> Wait wait.
20:16:51 <b_jonas> Does Wizards have at least three different announcements for the second Conspiracy set, each giving a different name for the set?
20:17:00 <b_jonas> Wtf.
20:17:11 <b_jonas> It's not April's Fool yet
20:17:42 <b_jonas> um, M:tG set
20:18:01 <hppavilion[2]> ais523: Do you understand the rho-calculus?
20:18:09 <ais523> hppavilion[2]: no
20:18:16 <hppavilion[2]> ais523: Damn
20:18:28 <hppavilion[2]> ais523: I was hoping to incorporate rho expressions into EsoLISP
20:18:46 <ais523> b_jonas: basically they had one announcement that they edited a couple of times, citing events in the plane on which Conspiracy takes place having overtaken them
20:19:03 <ais523> first they announced it was about Brago, but then a few hours later they announced that Brago had been assassinated
20:19:07 <ais523> so they had to change the name of the set
20:19:18 <b_jonas> I see
20:19:24 <ais523> (also they removed one card from it)
20:19:33 <ais523> then today they went and added a card back in and renamed it again
20:19:52 <b_jonas> as in, removed Brago?
20:19:55 <hppavilion[2]> ais523: Is a #esoteric official LISP a decent idea?
20:20:01 <ais523> b_jonas: they didn't say which card was removed
20:20:08 <ais523> hppavilion[2]: you'll never get #esoteric to agree on an official anything
20:20:26 <ais523> also, I don't agree with restricting the language choices that the channel can use
20:20:28 <hppavilion[2]> ais523: A #esoteric pseudo-official LISP?
20:20:30 <ais523> sometimes one langauge is better than another
20:20:36 <hppavilion[2]> ais523: It's not a restriction
20:20:51 <hppavilion[2]> ais523: It's just as restricting as forget-me-nots being the Alaska state flower
20:20:54 <ais523> are you creating an esolisp or just a regular lisp specialized for implementing esolangs?
20:21:00 <ais523> hppavilion[2]: oh I see
20:21:00 <hppavilion[2]> There's no rule against actually using it
20:21:07 <hppavilion[2]> *against not using them
20:21:16 <hppavilion[2]> ais523: I think the goal is to do both xD
20:21:31 <ais523> but Underlambda isn't a lisp :-P
20:21:37 <hppavilion[2]> ais523: A LISP designed for implementing esolangs in an eso way :P
20:21:49 <ais523> (actually, that's aiming for three goals: being an esolang, being easy to implement esolangs with, and being easy to implement in esolangs)
20:21:52 <b_jonas> wait, "new conspiracies that twist the rules against your foes"? how is that an interesting feature of the set? that's the point of one of the Golden Rule: M:tG cards often change the rules, and usually in a way that helps you against your foes.
20:22:03 -!- Sprocklem has quit (Ping timeout: 246 seconds).
20:22:09 <hppavilion[2]> ais523: And I want to incorporate rho expressions- rhoexp : lambdaexp :: rhocal : lambdacal
20:22:13 <b_jonas> Why do they put such meaningless marketing language in the annoucnement?
20:22:32 <ais523> b_jonas: all announcements seem to be like that
20:23:01 <ais523> the people who get annoyed by them aren't the audience that the announcement is aiming to reach
20:23:28 <ais523> you might want to read through the most recent GDS (sadly I don't have a link), one of the things they discussed was marketing taglines
20:23:39 <b_jonas> hmm
20:23:47 <b_jonas> the most recent one is the second one, right?
20:25:29 <ais523> I think so
20:26:42 <b_jonas> I do remember fake set names given, but most of them were for reprint sets with the announcements on April's Fools, with the exception of Mirrodin Pure in which case they were clear about how it can be fake from first place.
20:26:58 <b_jonas> You remember Mirrodin Pure, right? That was marketing for a future set done right.
20:28:16 <b_jonas> `? mirrodin pure
20:28:19 <b_jonas> `? icfp
20:28:22 <b_jonas> `? icfp contest
20:28:26 <HackEgo> icfp contest? ¯\(°​_o)/¯
20:28:26 <HackEgo> icfp? ¯\(°​_o)/¯
20:28:26 <HackEgo> mirrodin pure? ¯\(°​_o)/¯
20:29:17 <b_jonas> Oh, that reminds me
20:30:23 <b_jonas> There's an esolang for which I should create an article on the wiki. Or at least I think it's an esolang.
20:31:18 <b_jonas> If a new language is created for the purpose of the designer wanting to create an implementation for a language, but with limits that make the language very restricted or hard to use,
20:31:36 <b_jonas> but the goal isn't to make the language bad, but to make the implementation simple under some conditions,
20:31:50 <b_jonas> then would that count as an esolang, or is it instead a non-esolang for educational purposes?
20:32:12 <hppavilion[2]> Huh. eso- means "within"
20:32:46 <Taneb> b_jonas: brainfuck and FALSE are both in that category
20:33:04 <Taneb> (both designed to have small compilers)
20:33:05 <b_jonas> Taneb: ah yes, and I think Mouse is too
20:33:31 <b_jonas> although brainfuck is sort of a special case, because it's very early
20:35:24 <b_jonas> Hmm, I wonder if I have my implementation for this stuff. Although it's very simple-minded, so I might not actually want to publish it.
20:36:27 <b_jonas> I wrote it ages ago, and I'm not sure where it is. Probably only somewhere in my old backups.
20:36:41 <b_jonas> (I found a doc-bug with it.)
20:37:30 <b_jonas> Ok, whatever, if someone wants, they can just write a new implementation. It's not hard.
20:38:34 -!- Sprocklem has joined.
20:41:55 <ais523> b_jonas: Mirrodin Pure backfired I think, there are /still/ people asking for the card list to be released
20:42:15 <Vorpal> <ais523> b_jonas: basically they had one announcement that they edited a couple of times, citing events in the plane on which Conspiracy takes place having overtaken them <-- okay that is a neat PR thingy
20:43:26 <b_jonas> ais523: strange. I sort of remember some people writing that they thought Wizards has actually made two sets and were to decide on which one to release very late, but I don't understand where that came from, because it seemed clear enough from their communication that that's not the case.
20:44:12 <b_jonas> ais523: although I'm not surprised that people are confused _now_, because the Wizards webpage is horrible, it's hard to find information about old sets and other old stuff
20:44:40 <ais523> every time they try to change the website they make it worse :-(
20:44:45 <Vorpal> what is the prefix for lambdabot now again?
20:44:51 <ais523> the general consensus just seems to be that Wizards are terrible at computers
20:44:52 <b_jonas> ais523: that too, sure
20:44:54 <ais523> Vorpal: @ or ?, both work
20:45:00 <Vorpal> ah, thanks
20:45:11 <ais523> or > as an abbreviation for @run
20:45:13 <b_jonas> ais523: yes, which is strange, because that's a problem they could fix by, you know, hiring people who are good at computers
20:45:30 <b_jonas> finding such people should probably be easier than finding people who are good at making games
20:45:35 <Vorpal> Hm it doesn't seem to respond in /msg? Pretty sure that used to work
20:45:39 <ais523> b_jonas: it could be that they're don't think that would be value for money
20:45:48 <b_jonas> ais523: maybe
20:45:48 <Vorpal> Oh there we go, it was just super slow
20:46:28 <ais523> <ais523 to lambdabot> @run 4 <lambdabot to ais523> mueval-core: Time limit exceeded
20:46:32 <ais523> int-e: you may have a runaway process
20:46:55 <Vorpal> ais523: no kidding
20:47:01 <b_jonas> ais523: if I want to find listings of old theme decks (and other preconstructed decks), that's hard directly from their site, but the links to the listings are collected on en.Wikipedia (luckily the links to their articles don't usually break, I have to give that much to them)
20:47:24 <b_jonas> ais523: but if I want to find the set FAQs (release notes) for old sets, I'm out of luck, I have totally no way of finding them
20:47:25 <hppavilion[2]> esolinguiratia: Frustration caused by trying to program or speak in a language that makes absolutely no sense, particularly one not meant to be used, particularly when you're clueless to the fact that you aren't supposed to use it
20:47:36 <ais523> b_jonas: the links to the articles broke a while back and it took them like a week to fix them
20:48:00 <b_jonas> ais523: if I want to find older states of the Gatherer, I have to go to Yawgatog's site. I also have to go there if I want all the info from the Gatherer in a sane format.
20:49:08 <b_jonas> At least they have now fixed Gatherer to show flip cards and split cards in a sane manner, which was a long-standing bug, only now there are double-faced cards too, and THEY aren't shown in a sane way.
20:49:20 <b_jonas> (I don't know about level up cards, I haven't checked that.)
20:49:54 <b_jonas> And one small detail that really annoys me is that they don't have a complete list listing the official two or three letter codes for all old sets.
20:50:14 <b_jonas> You can try to guess from various filenames on their websites, but it turns out that for old sets they're sometimes inconsistent.
20:50:30 <b_jonas> en.wikipedia has a list, but I'm not sure it's always correct
20:51:00 <b_jonas> Wizards has at least made the http://magic.wizards.com/en/game-info/products/card-set-archive page much saner than it used to be,
20:51:29 <b_jonas> so now you can find a list of really ALL sets Wizards ever released (Astral isn't there, but that's not a product by Wizards, but I don't think anything else is missing),
20:52:02 <b_jonas> but from that page and what it links to, you can't find the set faqs, the codenames, and other important information.
20:52:23 <b_jonas> So there's some things they've improved, but also some things they've never fixed.
20:54:51 <b_jonas> On esowiki, is there a category for languages that are fully specified, in the sense that there's no undefined behavior in them that you could use for a future extension?
20:56:16 <b_jonas> Such as mod 256 BF with a tape infinite both left and right
20:57:27 <hppavilion[2]> ais523: Perhaps I could get people to like Esolisp by adding any good functions requested by channel members to either builtins, the stdlib, or (for large function groups), an external library
20:57:45 <ais523> b_jonas: I don't think so
20:57:57 <ais523> there were some unauthorized categories created recently and nobody cared to do anything about it
20:57:58 <myname> what about the eso standards?
20:58:02 <ais523> so you /might/ be able to get away with it
20:58:13 <ais523> myname: those were mostly arguments about how to standardize the standardization process
20:58:27 <ais523> I'm not sure we got around to standardizing any actual languages
20:58:27 <myname> lol
20:59:31 <b_jonas> ais523: I got away with it once, but I don't think I'll create one for this
20:59:43 <b_jonas> It's probably a bad idea to use a category for this in fact,
20:59:59 <myname> why?
21:00:00 <b_jonas> since it will often happen that a language has several variants, grouped in the same article, and only some are fully specified
21:00:03 <b_jonas> like with Brainfuck
21:00:29 <myname> buildung a subpage?
21:01:11 <b_jonas> nah, often there are just too many variants and we're lazy
21:02:18 <b_jonas> Ok, let me see what other categories I need then. I need a year, and [[Category:Finite state machine]] since the amount of memory is fixed and small.
21:02:41 <b_jonas> Ah, and I need [[Category:Implemented]]
21:03:35 <b_jonas> Hmm, does [[Category:Non-textual]] count if the program is a binary file (machine code) rather than a text source?
21:05:13 <b_jonas> By the way, why don't we have a separate Appendix: namespace on the wiki for entries that aren't describing a language, eg. [[David Morgan-Mar]]?
21:05:33 -!- augur has joined.
21:05:36 <ais523> I don't think we normally use non-textual for binary
21:05:47 <ais523> and because we have Category:Languages
21:05:58 <ais523> it's meant to be a site about esolanging, not necessarily a directory of esolangs

21:06:15 <b_jonas> ais523: of course, but still, I think this is what mediawiki namespaces for
21:06:33 <b_jonas> or at least it's how *.wiktionary uses the namespaces
21:06:36 <ais523> esolang's modelled quite heavily on wikipedia
21:06:50 <ais523> (I think it was originally started because of mass esolang deletions on wikipedia?)
21:06:59 <b_jonas> ok, whatever
21:07:12 <b_jonas> I'll just write the article now

22:08:47 <b_jonas> There's some strange syntactic elements in it, like how there are no mandatory semicolons so the statements are separated in a strange way, sort of like lua; and how the dereference operator has a higher precedence than the function call operator; but I think these are only strange to use because we're so used to C.
22:08:52 <b_jonas> They're definitely not eso.
22:10:05 -!- AlexR42 has quit (Quit: My Mac has gone to sleep. ZZZzzz…).
22:11:42 <b_jonas> Also, it's so much a one-pass compiler that it doesn't even ever patch addresses or values emitted earlier, so there's absolutely no way to refer to symbols defined later.
22:11:51 <b_jonas> Which leads to some strange things.
22:11:59 <b_jonas> But again, it's certainly not eso by intent.
22:15:25 <impomatic_> Doesn't Viktor Toth also run an implementation of the original Essex MUD?
22:15:36 <b_jonas> impomatic_: he runs some mud, but I'm not sure what
22:15:39 <zzo38> I suppose it can therefore support streaming and may use less memory than otherwise
22:16:58 <b_jonas> zzo38: the webpage says the goal was to use little memory, but I think the actual reason is to make the implementation simple, since the computer he runs them on has a whole MEGABYTE of memory, and runs DOS, and that's more than enough to run a bigger compiler than this properly
22:17:43 <b_jonas> zzo38: since it writes the output to a DOS file, storing addresses it has to patch in RAM and later patching them with seek wouldn't be very hard
22:17:49 <b_jonas> it would still make it a one-pass compiler
22:18:13 <zzo38> Yes but such thing could be made also which using stdout
22:18:19 <b_jonas> even in the sense that the compiled output is ready to run, no need to link
22:18:35 <b_jonas> zzo38: on DOS, that doesn't have any significance, because DOS doesn't have pipes
22:18:47 <b_jonas> zzo38: would you want to output the compiled program to a serial prot?
22:19:43 <b_jonas> Wait
22:19:51 <b_jonas> I think I know the reason
22:20:02 -!- AnotherTest has quit (Quit: ZNC - http://znc.in).
22:20:27 <b_jonas> he doesn't use all 1 megabytes of memory (or a large part of it), since the compiler is implemented in itself, which makes accessing segments difficult. thus, programs, including the compiler, generally only use linear addresses within one segments,
22:20:49 <b_jonas> so he has a total of 64 kilobytes of data memory
22:20:57 <b_jonas> but even in 64 kilobytes, this wouldn't be too hard
22:21:15 <b_jonas> symbol backpatching would easily fit since he already has a symbol table
22:21:26 <b_jonas> for referring to symbols defined earlier
22:29:08 <b_jonas> But then, who am I to criticize him? I never wrote a compiler similar to this.

22:31:55 <Phantom_Hoover> oi Taneb
22:32:02 <Taneb> Hi, Phantom_Hoover
22:32:32 <Phantom_Hoover> do you have room in the leeds slash york area for 16 people to sleep tomorrow night
22:32:55 <Taneb> That is very sudden, also no
22:33:16 <Taneb> This your submarine jousting or whatever?
22:33:52 <Phantom_Hoover> yes
22:34:19 <Phantom_Hoover> turns out yorkshire isn't full of conveniently available couches like plymouth is
22:34:26 <ais523> how does submarine jousting compare to bf jousting?
22:34:42 <Phantom_Hoover> substantially different
22:41:09 <Taneb> Phantom_Hoover: I've asked in the computer science in York channel but I wouldn't be to hopeful
22:41:37 <Taneb> The response thus far has been, and I quote, "noy to the lot of you"
22:43:10 <impomatic_> ais523: looking for early mentions of iterated (or repeated) Prisoner's Dilemma turns up a few from the late 50s but they all appear to be behind a paywall :-(
22:44:13 <Taneb> Phantom_Hoover: ooh, I've got a "depends on your threshold for standards of living"
22:57:56 <Phantom_Hoover> lol
22:58:07 <Phantom_Hoover> i think we're committed to driving home by now anyway
22:58:56 <Phantom_Hoover> thanks for the offer though, ofc. you can still show up for an extremely impromptu and distracted #esoteric meetup
23:01:30 <Taneb> You're playing tomorrow?
23:01:34 <Taneb> Alas, I'm in Hexham

23:06:27 <impomatic_> Is this jousting with real submarines? In the river?
23:07:00 <Phantom_Hoover> no, it's hitting a puck on the bottom of a pool with a little stick

23:10:16 <Phantom_Hoover> Taneb, that's probably for the best given that we're probably going to embarass ourselves totally

23:41:37 <hppavilion[2]> So, crazy idea
23:42:16 <hppavilion[2]> A language- called World Wide Web Calculus (or WCalc)- that basically is a formal mathematical system for web programming
23:43:06 <hppavilion[2]> Kind of amalgamating pi calculus, simply-typed lambda calculus, and some other things into a single, unified language that lets you use math as server-side programming
23:43:32 <hppavilion[2]> With things like HTTP requests as primitive objects
23:46:43 <hppavilion[2]> Of course, completely declarative
23:49:40 <rdococ> what about a language like HTML, but it programs stuff?
23:50:22 <rdococ> and then it has a <tpircs> tag which describes what the LMTH page looks like (yeah, fancy backwards ffuts)
23:54:34 <hppavilion[2]> O, hai rdococ
23:54:38 <hppavilion[2]> Haven't seen you in a while
23:54:45 <hppavilion[2]> Not since my first few weeks on IRC
23:54:47 <hppavilion[2]> :)
23:57:16 <rdococ> hai yay
23:57:45 <hppavilion[2]> rdococ: I'm making a demonstration HTTP server
23:58:13 <FireFly> You should probably abbreviate he World Wide Web Calculus as W3C
