01:39:10 <pikhq> All in favor of me writing an OS?
01:39:26 <lament> No.
01:39:27 * pikhq shouts 'Aye'
01:40:05 <ehird> No.
01:40:07 <ehird> I tried it once.
01:40:12 <ehird> It's not exciting.
01:40:13 <ehird> Or fruitful.
01:40:16 <pikhq> And where'd you get stuck?
01:40:26 <ehird> At the part where it became terminally boring.
01:40:34 <pikhq> . . . Which is?
01:40:36 <lament> so right at the start, then :)
01:41:04 <slereah_> I'm for it, as long as I'm not you.
01:41:23 <ehird> lament: And all the way through.
01:41:35 <slereah_> Regular OS, or eso OS?
01:41:44 <pikhq> I dunno.
01:41:49 <pikhq> Esomic is quite tempting.
01:42:27 <pikhq> ATM, I'm just fiddling with basic routines for doing text mode without the BIOS.
01:44:35 <lament> pikhq: think: it's a LOT of fairly meaningless porting work.
01:45:04 <pikhq> lament: I think I noticed already.
01:45:21 <pikhq> I'm terminally bored, though. Might as well do *something* with that terminal boredom.
01:49:14 <lament> design a really cool non-esoteric programming language
01:49:29 <lament> a better lisp, perhaps :)
01:50:02 <lament> to qualify, it has to be better than anything else in existance.
01:50:36 -!- ehird has quit ("Konversation terminated!").
01:50:52 <slereah_> Non-esoteric? Doesn't that require a lot of instructions? :o
01:51:23 <slereah_> What's the shortest instruction set for a non-esoteric language that isn't machine code?
01:54:36 <lament> machine code languages probably have the biggest instruction sets
01:54:51 <pikhq> That depends: what do you consider an esolang? :p
01:54:53 <lament> also, what's an "instruction"? Any builtin?
01:55:21 <pikhq> If you consider Lambda calculus non-esoteric, then there you go.
01:55:25 <slereah_> Well, if it's CISC yes.
01:55:55 <slereah_> Well, built in in the basic language I suppose.
01:56:04 <slereah_> Without the modules and whatnots.
01:57:02 <pikhq> Well, in *that* case. . .
01:57:09 <pikhq> Hmm.
01:57:16 <pikhq> Lisp? :p
01:57:43 * pikhq shrugs
01:59:37 <lament> lisp/scheme has very few
02:01:40 <lament> pikhq: do it! there aren't enough amazingly awesome languages.

03:53:04 <RodgerTheGreat> pikhq: behold a doodle! http://www.nonlogic.org/dump/images/1204661750-arch.png
03:53:33 <oklopol> it's got all kinda feet!
03:53:37 <oklopol> *kindsa
03:53:56 <RodgerTheGreat> they're all four-toed, just in different orientations
03:55:03 <oklopol> well, my point was in no way anything. i should really start tagging my actually meaningful sentences somehow...
03:55:10 <RodgerTheGreat> haha
03:55:14 <oklopol> :P
03:55:23 <pikhq> Heh.
03:55:37 <RodgerTheGreat> likin' the character design overall?
03:55:49 <pikhq> IRC with sentence tagging. Good idea?
03:55:55 <pikhq> (very Web 2.0, BTW.)
03:55:59 <RodgerTheGreat> I think I've finally figured out a design for the leg mechanics that I'm happy with.
03:57:02 <oklopol> i should sleep...
03:57:28 <oklopol> why the fuck would i drink a couple of energy drinks at about midnight, when i want to wake up early
03:58:01 <pikhq> Because sleeping is bad for you.
03:58:02 <Sgeo> I guess I should work on PSOX safety and finish the filesystem domain, then it's a release of 1.0b1
03:58:16 <Sgeo> pikhq, are you working on PSOX compatible tools?
03:58:29 <pikhq> Sgeo: No, I'm working on a simple kernel.
03:58:41 <Sgeo> Will anyone notice 1.0b1?
03:59:10 <pikhq> ATM, it just proves that I'm running in 32 bit mode.
03:59:43 <pikhq> (by running a 32-bit ELF with a Multiboot header, of course)
04:04:16 -!- pikhq has set topic: Gygax: May you get a perfect 20 on your 'rest in peace' saving throw. | #awesome | esoteric as always.
04:12:07 <Sgeo> Multiboot header?
04:12:31 <pikhq> The GNU Multiboot specification. . .
04:12:53 <pikhq> It's a generic method for a bootloader to talk to an OS kernel and load it into memory.
04:13:05 <pikhq> Works pretty well for most any OS.
04:13:28 <pikhq> One kernel using it is Xen. ;)

18:45:28 <AnMaster> for befunge93, is the input line based? that is, should it read one char (like fgetc), or a whole line (like fgets)? sure it should pass one char at a time to the code, but should it cache the results until the user hits enter?
18:45:42 <AnMaster> so should it be buffered or not?
18:46:01 <slereah_> I can't help you!
18:46:05 <slereah_> I know little of efunge.
18:46:16 <AnMaster> err, how is that related to befunge?
18:46:26 <AnMaster> ah
18:46:27 <AnMaster> sorry
18:46:28 <AnMaster> bad font
18:46:36 * AnMaster read "efunge" as "europe"
18:46:41 <AnMaster> weird mis-reading
18:47:57 <slereah_> Heh.
18:52:04 <AnMaster> slereah_, btw my bashfunge is going well

20:24:15 <louzer> What is meant by wrapping constants on wikipedia?
20:24:23 <louzer> *wiki
20:24:47 <louzer> I mean I went to BF wiki and found non-wrapping and wrapping constants
20:24:55 <louzer> what's the difference
20:25:29 <louzer> anyone?
20:25:49 <Judofyr> louzer: with wrapping means that if you increment 255, you'll get 0
20:26:08 <Judofyr> on some implementation it will just exit/crash the program
20:27:05 <oerjan> and some, strangely enough, have numbers bigger than 255...
20:27:30 <Judofyr> but most of the time, the wrapping-constants will work
20:27:31 <louzer> lets say I'm trying to print letter E. so if i use the wrapping code, and if I add 255 to the memory location after the byte with ascii E is formed.. the memory will become 0, crash or go higher?
20:27:54 <louzer> is that wat u mean?
20:28:13 <Judofyr> yes
20:28:18 <Judofyr> I think so :P
20:28:40 <louzer> hmm interesting..
20:28:47 <louzer> u know im starting to like BF
20:29:20 <oerjan> wrapping code may not give the ascii E to begin with
20:29:56 <louzer> I tried and it outputted E
20:29:56 <oerjan> (on a non-wrapping implementation)
20:30:17 <louzer> hmm is non-wrapping .. wrapping the property of the implemetnation?
20:30:29 <oerjan> yes
20:30:58 <oerjan> the non-wrapping code should work on all implementations that can support all byte values at all
20:31:39 <oerjan> wrapping code may only work on those which wrap 255 to 0 and vice versa
20:31:56 <louzer> finally! got it
20:32:01 <louzer> thank you
20:32:15 <oerjan> but for output, some of the wrapping codes _may_ work otherwise, but be slower, on implementations which truncate output to the last 8 bits (i think egobfi does this)
20:32:35 <louzer> hmm interesting
20:33:10 <oerjan> in that case the actual value produced may differ in the other bits
20:33:37 <oerjan> this is because most of the special wrapping code is based on tricks from modulo 256 arithmetic
20:33:48 <louzer> ok
20:34:08 <louzer> i cant believe this thing is turing complete
20:34:19 <louzer> haha
20:34:26 -!- jix has joined.
20:35:13 <louzer> if ur on mac os x what is the recommended bf interpreter
20:36:02 <oerjan> no idea
20:36:07 <louzer> its ok
20:36:52 <Judofyr> louzer: most interpreter for Linux will work for Mac too
20:37:08 <louzer> Judofyr: ok will compile one then
20:37:43 <Judofyr> louzer: Or find one in Python/Java/Ruby etc.
20:38:02 <louzer> Judofyr: yeah.. or write one
20:38:11 <Judofyr> yeah
20:38:16 <Judofyr> that's pretty easy
20:38:22 <louzer> hehe
20:40:23 <oerjan> i guess writing a brainfuck interpreter is the initiating rite for #esoteric, like writing a monad tutorial is for #haskell
20:40:43 <oerjan> i don't think i've done either, btw
20:41:00 <Judofyr> which language do you use?
20:41:27 <Judofyr> what*
20:41:33 <oerjan> mostly Haskell for what little programming i do nowadays
20:42:21 <Judofyr> oerjan: http://haskell.org/haskellwiki/Short_examples/BF_interpreter :)
20:42:35 <oerjan> oh i know it has been done
20:42:53 <oerjan> it's just i never finished mine
20:43:26 <oerjan> i've mostly done unlambda interpreters instead
20:46:50 <oerjan> what the heck the wiki example uses an actual foreign array
20:49:32 <oerjan> when it's so easy to use a pair of lists for unbounded tape
20:49:50 <Judofyr> oerjan: it's a wiki, you can improve it :)
20:50:13 <oerjan> well it's supposedly a particular interpreter
21:10:22 * SimonRC does sick things with C
21:10:29 <SimonRC> A Forth!
21:22:20 <SimonRC> in the style of that J interpreter
21:23:01 <ehird_> SimonRC: brillant
21:24:18 <SimonRC> "V(tl)for(;;){w.p=*ip.p;(*w.p+2)();}}
21:24:28 <ehird_> that's awesome
21:24:37 <SimonRC> the top-leve loop, with extraneous "
21:24:39 <ehird_> truly, how c was meant to be
21:24:42 <SimonRC> heh
21:25:35 <SimonRC> it means: forever: let w be what the ip reg points to; call the function whose address is stored at w+2
21:25:43 <SimonRC> w is pointing to the current word, BTW
21:26:14 <ehird_> SimonRC: plz show full source
21:26:15 <ehird_> :D
21:26:34 <SimonRC> the code for colon defs relies on w pointing to the current word, becuase it changes the ip to w[3]
21:27:33 <ehird_> SimonRC: I'm working on a concatenative functional language
21:27:37 <ehird_> like Joy & Cat
21:27:41 <ehird_> but strongly-typed like Cat
21:27:49 <SimonRC> ok
21:27:50 <ehird_> but cooler - I hope to make it *purely functional* like Haskell
21:27:53 <ehird_> Monads!
21:27:59 <SimonRC> grin
21:28:15 <ehird_> dip :: 'R 'a ('R -> 'S) -> 'S 'a
21:28:50 <ehird_> SimonRC: can't think of any fun examples to show you
21:28:51 <ehird_> :P
21:30:02 <ehird_> SimonRC: but it means that a stack underflow can never happen
21:30:05 <ehird_> since it is always a type error
21:30:13 <ehird_> and is therefore caught at compile-time
21:30:31 <ehird_> SimonRC: now tell me how awesome that is :p
21:31:29 <ehird_> or, you know. don't.
21:32:05 <SimonRC> sounds rather lie cat so far
21:32:07 <SimonRC> *like
21:32:26 <ehird_> SimonRC: yes
21:32:29 <ehird_> but far more awesome
21:32:43 <ehird_> because cat is not purely functional
21:32:50 <SimonRC> ah, ok
21:33:06 <ehird_> does cat have type inferrence?
21:33:08 <SimonRC> OTOH, stacks do tend to put an ordering on instructions
21:33:12 <ehird_> it seems to but not for functions
21:33:17 <ehird_> and no
21:33:20 <ehird_> you can reason about stacks functionally
21:33:27 <SimonRC> oh, yes
21:33:31 <ehird_> a function is `stack -> stack`
21:33:36 <ehird_> but with more constraints on 'stack'
21:33:37 <ehird_> like, dup:
21:33:44 <ehird_> 'R 'a -> 'R 'a 'a
21:33:47 <ehird_> where 'R is the rest of the stack
21:33:58 <ehird_> and then ' ' instead of being the application operator like in Haskell is the compose operator
21:34:02 <AnMaster> ehird_, what language is that?
21:34:08 <ehird_> AnMaster: ?
21:34:15 <AnMaster> that you are talking about
21:34:32 <ehird_> one i'm making
21:34:50 <AnMaster> what is it called?
21:35:07 <AnMaster> also, what about TURKY BOMB, did you get anywhere with the interpreter?
21:35:08 <ehird_> no name ye
21:35:08 <ehird_> tt
21:35:11 <ehird_> and not yet
21:35:13 <AnMaster> or did you give it up?
21:35:13 <ehird_> but i will work on it soon
21:35:50 <AnMaster> ehird_, did you say I wouldn't be able to do befunge in bash? ;P
21:35:58 <ehird_> I said Funge-98.
21:36:03 <AnMaster> it is befunge93, and quite a bit of befunge98
21:36:06 <ehird_> You are just doing Befunge-93 with one extension, which is trivial.
21:36:21 <AnMaster> ehird_, not one extension, I'm aiming at quite a few of them
21:36:26 <AnMaster> even the stack stack bit
21:36:42 <ehird_> until you get Fingerprints and Funge's topology rules..
21:36:48 <ehird_> its not even CLOSE
21:36:51 <ehird_> SimonRC: hmm
21:36:54 <ehird_> how WOULD monads work?
21:36:56 <AnMaster> ehird_, I do have fingerprints, partly
21:37:00 <ehird_> functions can return multiple values
21:37:07 <ehird_> but i cannot express that in a type to wrap it in 'm'
21:37:12 <AnMaster> ehird_, not fully yet however
21:37:51 <ehird_> bind :: 'R (m 'a) ('R 'a -> 'R (m 'b)) -> 'R (m 'b)
21:37:56 <ehird_> SimonRC: but that only handles one return value
21:42:16 <oerjan> m ('R 'b) obviously
21:43:20 <ehird_> oerjan: that wraps the whole stack in the monad
21:43:27 <oerjan> yes.
21:43:29 <ehird_> specifically, the stack gets reduced to one element
21:43:33 <ehird_> with the whole stack
21:43:39 <ehird_> oerjan: but that can include stuff not involved in the monadic computation
21:43:41 * SimonRC wonders what the pre-processor would do with a macro called $
21:44:10 <ehird_> oerjan: so that's incorrect
21:44:11 <SimonRC> will it recognise it in constructs like foo$bar?
21:44:11 <ehird_> SimonRC: which pre-processor?
21:44:12 <oerjan> i see. tricky.
21:44:18 <ehird_> SimonRC: if cpp -
21:44:19 <SimonRC> the c one
21:44:22 <ehird_> it uses c identifier rules#
21:44:27 <ehird_> so you can't define $
21:44:34 <SimonRC> oh
21:44:45 <SimonRC> does that mean I can't have a macro called ^ either?
21:45:19 * SimonRC calls in _ instead
21:45:21 <SimonRC> *it
21:45:42 <ehird_> SimonRC: that is correct
21:45:51 <ehird_> WAIT
21:45:53 <ehird_> NO DISREGARD THAT
21:45:55 <ehird_> $ is a valid macro nam
21:45:56 <ehird_> e
21:46:00 <SimonRC> cool!
21:46:03 <ehird_> but
21:46:10 <ehird_> SimonRC: it uses C breaking rules, but dumbified
21:46:11 <ehird_> #define $ 2
21:46:13 <ehird_> hello$world
21:46:14 <ehird_> -> hello$world
21:46:18 <SimonRC> :-(
21:46:24 <ehird_> the cpp is retarded
21:46:24 <ehird_> :)
21:47:19 <SimonRC> #define _ ;ip.p++;}
21:47:36 <ehird_> heh
21:47:41 <ehird_> SimonRC: that won't break though
21:47:43 <ehird_> you can't do a_b
21:47:57 <SimonRC> indeed, but it still looks good, even with the spaces
21:48:11 <ehird_> SimonRC: can i see the interp? :D
21:48:15 <SimonRC> not yet
21:49:06 <ehird_> aww
21:49:18 <ehird_> SimonRC: hehe, HUMAN-LOOKING DEFINITIONS:
21:49:28 <SimonRC> hm?
21:49:38 <ehird_> say-hi: "Hello, world!" print.
21:49:42 <SimonRC> ok
21:49:45 <ehird_> NAME: DEF.
21:51:05 <ehird_> fact: ('R Int -> 'R Int) dup 0 = [1] [dup 1 - fact *] if.
21:51:14 <ehird_> but ofc you can leave out the typedef
21:55:38 <ehird_> SimonRC: what functions does your forth have?
21:55:43 <SimonRC> the usual
21:55:56 <SimonRC> here are the binary operators, as defined in the source:
21:56:03 <SimonRC> B(ad,+) B(su,-) B(mu,*) B(di,/) B(an,&) B(or,|) B(xo,^)
21:56:36 <ehird_> SimonRC: ehm.. not traditional forth i take it...
21:56:49 <SimonRC> no, that is how they are defined in the C source
21:56:51 <ehird_> that is, 'if' isn't a word defined in forth in yours?
21:57:05 <SimonRC> not yet
21:57:16 <ehird_> IMO most 'forths' out there that aren't actual real ANS Forth are more like 'regular stack languages'
21:57:22 <SimonRC> yeah
21:57:37 <SimonRC> the secret of forth is factoring, simplicity, and smallness
21:57:42 <SimonRC> and hackability
21:57:47 <ehird_> SimonRC: jonesforth is the best example of what i'd consider "real forth"
21:57:55 <SimonRC> yes
21:57:55 <ehird_> i wouldn't call yours forth, probably :-)
21:58:00 <SimonRC> why?
21:58:08 <ehird_> well, I consider 'forth'ness to be an implementation attribute
21:58:12 <ehird_> not the external interface
21:58:26 <SimonRC> and?
21:58:33 <SimonRC> how is mine not forth?
22:00:11 <ehird_> SimonRC: it looks programmed at a too high level
22:00:11 <ehird_> :-P
22:00:30 <SimonRC> I am using lots of macros
22:04:19 * SimonRC wonders if there is a way to get macros to set up the initial dictionary
22:05:01 <SimonRC> heck, intialising is going to be really tough
22:05:10 -!- jix has quit ("CommandQ").
22:06:26 <ehird_> SimonRC: forth is a lot easier in asm
22:06:31 <SimonRC> yeah
22:06:36 <SimonRC> or in Forth :-)
22:07:07 <SimonRC> or in fact any language with a semi-decent macro system
22:07:49 <ehird_> nahh
22:07:51 <ehird_> asm is the easiest

23:28:07 -!- olsner has quit ("Leaving").
23:28:12 <ehird> Sgeo: I would argue with you, but I'm too busy despairing about PSOX every time it's mentioned.
23:28:46 <Sgeo> It's internal safety against mistakes, not safety against malicious PSOX programs
23:36:29 <pikhq> So, basically, it's more about adding a command to enable certain unsafe commands, just to prevent some poor Brainfuck coder from hitting rm * rather than ls.
23:38:53 <ehird> pikhq: Are you satirizing it?
23:38:55 <ehird> I hope so.
23:39:16 <pikhq> ehird: Just commenting ATM.
23:39:23 <pikhq> My satire is crueler.
23:39:43 <pikhq> So, basically, you're strapping a nuclear sub to a skateboard?
23:39:57 <ehird> pikhq: It's a nuclear sub with a little plastic cover over the torpedo buttons.
23:40:13 <ehird> Except that 'rm *' in PSOX would require a call to glob, etc.
23:40:18 <ehird> 'ls', significantly easier.
