00:09:58 <GregorR-W> Daemons have an associated channel.
00:10:07 <pikhq> Just figured that out.

00:18:44 <RodgerTheGreat> :S
00:19:13 <CakeProphet> Hmmm... oh dear.. I need to find an application for parabolas and make a problem out of it...
00:19:23 <CakeProphet> Give me a problem or something... that's easy to draw :D
00:19:49 <pikhq> d/dx(x^2). Have fun.
00:20:51 * pikhq laughs evilly
00:24:38 * CakeProphet doesn't get it.
00:24:55 <CakeProphet> Well, I need a real life application... which confounds me slightly.
00:24:57 <pikhq> Find the derivative of x^2.
00:25:26 <pikhq> Should be easy for at least *some* people in here. . .
00:25:57 <GregorR-W> ...
00:26:06 <pikhq> Although, since you're working on algebra homework, I'm just being a dick by talking calculus. XD
00:26:18 <GregorR-W> It's CLEARLY (1/3)x^3
00:27:06 <pikhq> GregorR-W: I'm afraid you're going to owe me a new keyboard if you keep that up.
00:27:53 <GregorR-W> You're right, it's (1/12)x^4
00:28:15 <pikhq> Yup. You owe me a new keyboard.
00:28:35 <pikhq> CakeProphet: For the record, it's really i^(2x*pi).
00:28:45 <Asztal> GregorR-W: You're SO wrong.
00:28:46 <Asztal> Plus a constant!
00:28:48 <Asztal> :D
00:29:49 <GregorR-W> Asztal: Damn, I was hoping nobody would notice!
00:30:04 <GregorR-W> It's actually (1/12)x^4+Ax+B where A and B are constants

00:33:16 <Asztal> I just realised this algorithm totally isn't going to work with negative numbers
00:37:22 <fizzie> I thought d/dx x^2 was \rho ( \frac{\partial u_\phi}{\partial t} + u_r \frac{\partial u_\phi}{\partial r} + \frac{u_r u_\phi}{r} + \frac{u_\theta}{r} \frac{\partial u_\phi}{\partial \theta} + \frac{u_\theta u_\phi \cot \theta}{r} + \frac{u_\phi}{r sin \theta} \frac{\partial u_\phi}{\partial \phi} )
00:37:38 <fizzie> No, wait... that's the beginning of one of the Navier-Stokes equations in spherical coordinates.

00:46:48 <CakeProphet> Hey, what's the mathematical method for finding the parabolic path of an object that is being pulled around by a planets gravity?

17:06:26 -!- kipple_ has joined.
17:17:30 <calamari> it seems like it should be possible to parse RPN using yacc.. but it seems much easier to handle infix.. it automatically stays balanced
17:26:05 <calamari> ahh, got it :) thanks google
17:27:02 <lament> the best way to parse RPN is the Forth way.
17:28:25 <calamari> I'm not really familiar with Forth.. what do you mean?
17:29:08 <lament> forth has the simplest parsing ever.
17:29:26 <lament> it takes the next word from the stream, words being tokens separated by whitespace.
17:29:43 <lament> and decides, based on that word, what it's gonna do next.
17:29:57 <lament> so the only parsing involved is determining whether a character is a space or not.
17:30:06 <calamari> ahh, but I'm trying to use yacc
17:30:25 <lament> and the cool thing about Forth is that Forth commands can affect parser behavior
17:30:29 <lament> for example
17:30:34 <lament> there's a special word "
17:30:55 <calamari> for strings?
17:30:59 <lament> once Forth encounters that word, the behaviour of the parser changes completely
17:31:11 <calamari> nifty
17:31:12 <lament> now it reads everything up to the next " as one token
17:31:25 <lament> note that " is just a function, you can write your own functions like that.
17:31:43 <lament> extending the parser in arbitrary ways
17:31:50 <lament> another special word is (
17:32:09 <lament> when ( gets executed, it reads off everything until a matching ) and simply discards it.
17:32:14 <lament> so ( blah) is a comment.
17:32:28 <calamari> cool, I think I have it.. will have to check for conflicts:
17:32:55 <calamari> expr -> num | expr num + | expr num - | num expr + | num expr -
17:33:11 <calamari> (very simplified of course)
17:33:19 * lament doesn't get it
17:33:48 <calamari> an expression can be a number, or an expression followed by a number followed by + or ...
17:33:56 <lament> what's an expression, in RPN?
17:34:05 <lament> no such thing :)
17:34:06 <calamari> 1 2 3 4 + - +
17:34:49 <calamari> that would be e => 1 e + => 1 2 e - + => 1 2 3 e + - + => 1 2 3 4 + - +
17:36:41 -!- Asztal has joined.
17:43:16 <lament> see, forth avoids those problems completely :)
17:43:37 <pikhq> RPN. :)
17:44:41 <calamari> hmm.. don't think I have it after all
17:44:53 <calamari> I can't seem to form 1 2 3 + 4 - +
17:45:03 <calamari> because the operators are always at the end
17:45:19 <lament> calamari: there's only one way to parse RPN.
17:45:37 <pikhq> calamari: With a stack.
17:46:12 <calamari> so you're saying that a LR(1) parser is incapable of parsing RPN?
17:46:24 <lament> calamari: RPN is already parsed, as long as you can split it into tokens.
17:46:26 <pikhq> Push 1, 2, and 3 onto stack. Do operation "plus" (pops 2 values from stack, add together, and push result).
17:46:30 <jix> expr => expr expr op | number
17:46:39 <pikhq> Push 4 onto stack. Do operation minus, then plus.
17:46:42 <pikhq> Simple, no?
17:46:43 <jix> dunno wether LR(1) can parse that
17:47:00 <jix> but that should be rpn
17:50:00 <calamari> jix: that works! thanks

21:39:49 <lament> GregorR-W: considering that it's not at all unlikely that stupidity is normally distributed, it's quite possible that the median and the mean coincide.

22:56:51 <Keymaker> (ps. the idea for making a language for ipod that's fast to type sounds interesting)
22:57:04 <pikhq> Mean, median, and mode are *all* measurements of central tendency.
22:57:21 <GregorR-W> Yeah. And "average" is "mean".
