02:36:46 <amenghra> hi, i just finished writing an esolang. I'm wondering if anyone thinks it's crazy (i.e. good) or lame (i.e. i wasted my time). http://quaxio.com/ajsone/
02:37:27 <Bike> this looks way too sensible
02:38:10 <amenghra> :(
02:39:06 <Bike> http://en.wikipedia.org/wiki/Category:XML-based_programming_languages
02:39:40 <amenghra> not sure those are all turing complete
02:40:09 <Bike> oh, here's the one i was thinking of http://www.o-xml.org/spec/langspec.html
02:40:54 <Bike> as you can see, you managed to make something about as good as this thing which somebody made seriously, and to explain it in just a page
02:41:33 <amenghra> http://en.wikipedia.org/wiki/POSXML
02:41:50 <amenghra> that one looks similar to my idea. Except json gives me less freedom than xml.
02:41:56 <Bike> «<callfunction name="showmessage" />» mein gott.
02:42:10 <amenghra> lol, I can't believe anyone would think that's a good idea!
02:42:18 <Bike> anyway i remember adding homoiconicity as long as you're jsoning
02:42:35 <Bike> recommend, not remember
02:42:46 <Bike> though really isn't all knowledge just rememberance of past lives, eh??
02:44:49 <amenghra> thanks for pointing out homoiconicity, http://en.wikipedia.org/wiki/Homoiconicity is a great read :)

09:37:23 <fizzie> IoH, the Internet of Houses; I hear it's a hot topic these days.
09:41:36 <Taneb> Is it bad that I get a real kick out of when I show someone a program I wrote and they reply "wtf is wrong with you"?
09:43:51 <int-e> sounds normal to me
09:44:13 <int-e> Then again I'm here on #esoteric, and so are you.
09:44:26 <Taneb> https://gist.github.com/Taneb/92c2273815931be07d97
09:47:22 <int-e> okay, playing with Church encodings on the level of gmp's C interface has not occurred to me before :P
09:47:32 <int-e> err
09:47:35 <int-e> Gödel
09:47:40 * int-e is still half asleep
09:49:56 <olsner> Taneb: I get that kick too, much more satisfying than someone saying it's good code (which, of course, no-one ever says anyway)
09:50:07 <int-e> (at least the encoding is based on a sane pairing function, not on prime powers)
09:51:42 <Taneb> int-e, I'd only use prime powers if I wanted a multiset
09:51:50 <Taneb> Rather than a bintree
09:51:59 <b_jonas> internet of houses? is that like geocities?
09:52:01 <int-e> Taneb: you could use mpz_bin_ui though
09:52:48 <b_jonas> int-e: it's not just the sane pairing function that matters, but also that you encode a sane expression tree instead of some flat parenthisized list
09:52:49 <olsner> might be nice to rewrite that thing in like haskell (or any language that has actual bignum support) so that it's possible to read it
09:53:10 <Taneb> olsner, it's actually a translation from Haskell
09:54:06 <int-e> olsner: even libgmp++ helps
09:54:16 <Taneb> int-e, instead of computing the triangle numbers manually? That's a thought

18:27:09 <douglass_> I had to have LaTeX add two numbers together once...
18:28:15 <zzo38> douglass_: There is the \advance command to add a number in TeX.
18:29:28 <zzo38> Do you know that?
18:29:36 <nooodl> "<quintopia> so tacuit is correct" <- i would say tacebat
18:34:39 <douglass_> it did eventually work; I don't recall which command I used. I just remember it being a pain in the ass to add one register to another as opposed to adding a fixed number to a single register.
18:41:34 <zzo38> It isn't; using \advance you can easily add one register to another.
18:44:25 <b_jonas> zzo38: sure, but it may get worse if you insist on using the crazy abstractions in LaTeX
18:44:47 -!- tromp_ has joined.
18:45:44 <zzo38> b_jonas: Ah, OK, although I just use Plain TeX and don't need to worry about abstractions

19:51:28 <zzo38> Do regular expressions define all haltable NFAs?
19:54:26 <Melvar> “haltable”?
19:54:49 <zzo38> I mean ones that are not guaranteed to not halt.
19:55:39 <Melvar> Don’t NFAs always halt?
19:56:13 <Bicyclidine> i think so. i mean, finite.
19:56:37 <Bicyclidine> no, right, you could have a loop, it's just that you could determine that beforehand.
19:56:59 <zzo38> I think it can be possible to make an infinite loop that never want any input, or you can get an error (which doesn't count as halting), or have infinite input, etc
19:57:39 <Melvar> You can only have a non-consuming loop if you use ε-NFAs …?
19:57:58 <zzo38> Melvar: Yes
19:58:32 <zzo38> The NFAs in this book allow one line to have a lambda on it to not consume input.
19:59:44 <Melvar> Then I guess that book has a definition of NFA that I don’t know, so I don’t think I can help.
20:00:31 <zzo38> It also describes DFA, which means that are no lambdas and furthermore that each possible input symbol has a unique successor state to each state.
20:02:57 <fizzie> The lambda is the same as the epsilon.
20:03:18 <olsner> I think you can do the normal NFA-to-DFA conversion even if there are epsilon transitions, basically merging all states reachable via epsilon transitions
20:03:42 <zzo38> Yes this book describe exactly how you do that, in fact.
20:03:45 <Melvar> Indeed. Any ε-NFA is convertible into an NFA is convertible into a DFA.
20:03:50 <olsner> which means they are regexps
