01:14:39 <Razor-X> Our AP Physics teacher teaches everything but Physics.
01:14:51 <Razor-X> Once he spent 2 hours lecturing about fats and carbohydrates.
01:14:53 <GregorR> I had a similar experience.
01:15:16 <Razor-X> A friend of mine the other day got him to spend 1 hour on the cleanup procedures of liquid mercury.
01:15:21 <GregorR> Incidentally, AP sucks, it screwed me into taking more advanced (and degree-unrelated) science in college than I would have had to otherwise.
01:15:32 <Razor-X> And he is convinced that he has to make faulty real-life analogies to Physics concepts.
01:16:24 <Razor-X> His worst so far was comparing formulas with that researcher that discovered that there are only 5 social links between you and some famous person.
01:17:07 <Razor-X> Also, he seems convinced that kids of the US can't handle SI units.
01:17:33 <Razor-X> AP Chemistry gave me a good handle on SI units, so he just sounds like an idiot to me.
01:21:20 <Razor-X> One of his best examples of stupidity ``You can use this to find a relationship of the viscosity in each day. Now use Calculus, take it to its limit. You can use Calculus to find the viscosity on the 3rd day, 7th hour, 6th minute''. Most of us try our hardest not to laugh our heads off at him because he hasn't realized that you can use fractional days.
01:22:34 <xor> You know what's cool?
01:22:37 <xor> emacs calc
01:22:41 <Razor-X> Heh.
01:22:55 <xor> I just found out about it
01:23:02 <Razor-X> I've decided to program something that allows you to play MIDI files on the Palm.
01:23:37 <Razor-X> With only one instrument, though.
01:26:44 <xor> How does your palm output sound?
01:27:00 <Razor-X> Beeps, but the beeps can be for different durations at different frequencies.
01:32:05 <xor> calc is awsome
01:36:01 <lament> Razor-X: converting units is one of the things he's supposed to teach, though.
01:36:08 <lament> Razor-X: giving you fractional days would be too easy.
01:38:39 <xor> ooooh
01:38:51 * xor likes the "a %" command in calc

01:41:22 <ihope> 333333333!
01:41:31 <xor> indeed
01:52:03 <Razor-X> lament: But he doesen't know Calculus.
01:52:15 <Razor-X> Or rather, he's forgotten.
01:56:20 <Razor-X> *he has forgotten

02:08:04 <lament> Razor-X: perhaps i don't understand the situation
02:08:17 <lament> Razor-X: i don't see how calculus is applicable
02:10:10 <Razor-X> It isn't.
02:10:32 <Razor-X> Of course, he thinks it does.
02:11:07 <lament> did you have a formula for viscosity, or experimental data with values for each day?
02:11:14 <Razor-X> Experimental data.
02:11:28 <Razor-X> He was talking about making a regression, but I wonder if he remembers any statistics at all.
02:11:45 <lament> oh, well, if it's experimental data, certainly you can apply calculus to it.
02:12:09 <Razor-X> Of course.
02:12:26 <lament> what's a regression?
02:13:00 <Razor-X> You have a bunch of data and try to apply an equation to it that will encompass the data, and hopefully hint at future trends.
02:13:06 <lament> i'd imagine any reasonable uncertainty on that viscosity would render the result completely useless...
02:13:38 <Razor-X> Advice when regarding my Physics teacher's advice:
02:13:42 <lament> oh, that's difficult
02:13:44 <Razor-X> Don't devote too many brain cycles.
02:14:28 <lament> i suppose you can assume the function is reasonably smooth...
02:14:45 <lament> but who knows, with daily changes in temperature, moisture and whatnot

19:03:19 <xor> odd
19:03:34 <xor> what's the point of >>><<< ?
19:03:35 <oerjan> even
19:03:58 <oerjan> that txtgen is not very smart
19:04:04 <pgimeno> xor, it's a genetic algorithm, that part is not optimized out automatically
19:04:31 <pgimeno> !bf_txtgen heh
19:04:47 <RodgerTheGreat> then it sounds like running it through a simple filter before displaying it's results would enhance the program.

19:07:28 <xor> what is the [24] ?
19:07:47 <pgimeno> I think it's the number of iterations or something
19:08:03 <pgimeno> but I'm wondering why it always produces >>><<<

19:09:28 <oerjan> i think possibly the inner loop generates an array of constants, which always has the same length even if only one is used.
19:09:30 <RodgerTheGreat> seems like a rather serious bug.
19:09:33 <xor> We could, you know, look at the source
19:09:45 <oerjan> !bf_txtgen Argle bargle, glop glyf
19:09:54 <RodgerTheGreat> !bf_txtgen a somewhat longer example sentence

19:12:41 <xor> pgimeno: No, it's written in C
19:12:47 <RodgerTheGreat> the algorithm seems to be designed for longer sentences.
19:12:57 <pgimeno> oh
19:14:58 <xor> the algorithm is slooooow
19:15:29 <RodgerTheGreat> genetic algos tend to be slow.
19:15:51 <xor> yeah
19:16:10 <xor> anyone have to url for the source?
