02:40:21 <oerjan> @tell edwardk i saw this post https://mail.haskell.org/pipermail/libraries/2015-July/026061.html i feel like you are pointing out the real elephant in the room for getting _any_ nontrivial (i.e. not just syntactic sugar) GHC extension standardized by this point...
02:50:32 -!- Walpurgisnacht has joined.
02:53:25 <tswett> So I know more or less how to find a ratio of integers that most closely approximates an irrational ratio.
02:53:45 <tswett> Now I wanna know: how do you find a ratio of integers that most closely approximates an irrational ratio of *three* numbers?
02:54:12 <tswett> Like, for example, the ratio 2:3:5 is a pretty good approximation to the ratio 2.1:3.1:5.1.
02:54:35 <tswett> 100:314:272 is a good approximation to 1:pi:e. Get what I'm saying?
02:55:03 -!- hppavilion[1] has quit (Ping timeout: 246 seconds).
02:55:09 <tswett> Given three positive numbers a, b, c, I want to multiply them all by some constant k, such that ka, kb, and kc are all close to integers.
02:55:12 <tswett> But I also want k to be small.
02:55:36 <tswett> How can I find the best values of k?
02:56:25 <tswett> Yet another statement...
02:57:10 <tswett> I know of a line in 3-dimensional space which passes through the origin. How do I find lattice points which are close to the line, but also close to the origin?
03:00:02 <oerjan> i'm not sure that's a line
03:00:36 <tswett> The line traced by (ka, kb, kc) as k varies? That's a line.
03:01:14 <coppro> tswett: define a fitness metric and then do an optimization problem on it?
03:01:23 <oerjan> but you also want k to be integer
03:01:32 <tswett> k doesn't need to be an integer.
03:02:06 <tswett> I guess given a candidate lattice point, the error can be represented as a vector. It's just the displacement between the lattice point and the closest point on the line.
03:03:10 -!- GeekDude has quit (Quit: {{{}}{{{}}{{}}}{{}}} (www.adiirc.com)).
03:03:11 <tswett> The space of all possible error vectors is 2-dimensional.
03:04:42 <tswett> So if you have a bunch of candidate lattice points, you know all their error vectors. If you have two error vectors of approximately the same length pointing in approximately opposite directions, you can add the lattice points together, and the error vector will just be the sum of the error vectors.

03:39:39 <tswett> Aha, I have discovered the ULTIMATE MICROTUNING.
03:39:43 <tswett> 848 equal temperament.
03:43:00 <tswett> An octave is exactly 848 steps. A perfect fifth is 496.048 steps, and a major third is 272.995 steps.
03:43:30 <tswett> These are better. Let me demonstrate.
03:44:13 <tswett> A perfect fifth is 701.955 cents, and a major third is 386.314 cents.
03:44:43 <tswett> So cents do a poor job of representing intervals as almost-integers.
03:45:35 <tswett> If you round everything to the nearest integer, then one major third is 386 cents, whereas two major thirds is 773 cents. How horrible!
03:45:47 <shachaf> Oh, that's what you were asking about ratios for.
03:46:04 <shachaf> But why stop at fifths and thirds?
03:46:34 <tswett> Because my ears are 5-limit.
03:47:02 -!- Sprocklem has joined.
03:47:13 <tswett> With 848 equal temperament, you'd have to stick eleven perfect fifths on top of each other in order to find something for which rounding error is significant.

09:44:50 <mroman> fizzie: I can see that it is trespassing of some sort
09:44:56 <mroman> but you can't really do anything about it.
09:45:07 <mroman> because shooting it with a gun is really unreasonable
09:45:28 <mroman> although it is not very likely but bullets falling down can cause damage
09:45:47 <mroman> if you shoot it more elliptically then that likelihood increases a lot.
09:46:30 <mroman> and I mean... it's up to x-feet that belongs to your "privacy zone"
09:46:42 <mroman> drones could just fly higher and have cameras with good optical zoom
09:47:32 <mroman> the most reasonable thing would be to ban flying drones with cameras and/or microphones
09:47:45 <mroman> without an explicit permit
09:48:04 <mroman> and put a huge fine on offenders
09:48:17 <mroman> because it's going to be hard to track them :D
09:52:43 <Jafet> Perhaps we should broadcast no-trespassing signs from WiFi access points.
09:52:59 <mroman> and that would do what?
09:55:48 <Jafet> About as much as a camera drone ban, I suppose.
09:56:21 <mroman> if you ban them you have legal "pressure"
09:56:46 <mroman> just because a law is hard to enforce isn't a reason not to have it
10:12:58 <Jafet> Or just apply the same rules as for manned aircraft -- restriction to airways and ATC instructions.

17:59:55 <constant> run it on first google result for "hippo"
18:00:17 <constant> I have more ideas if you want to hear them

18:25:45 <tswett> I agree with fungot. int-es indentation was incredible.
18:25:46 <fungot> tswett: yes, a very silly way: by implementing another turing machine in it. :)
18:26:13 <tswett> I mean, the way that int-e interpreted another Turing machine in the indentation? It was very silly, but incredible.
18:26:21 <tswett> s/interpreted/implemented/
18:26:44 <int-e> yeah, I'm amazing... wait, what happened here?
18:26:54 <fungot> int-e: its ban time!!! eheheheheeheheheh the guy
18:27:27 <tswett> Isn't there someone here that was working on a way of doing exact real computation of some kind?
18:28:28 <hppavilion[1]> What would be a weird data structure to base a filesystem around?
18:28:55 <tswett> Like, using something—I feel like it might have been similar to continued fractions or something—that can represent a lot of different real numbers exactly.
18:28:55 <hppavilion[1]> I mean, I guess an exposed linked list would be weird
18:29:03 <tswett> hppavilion[1]: a queue would be pretty weird.
18:29:13 <tswett> There are only two operations: "create a new file" and "read the oldest file and delete it".
18:29:25 <tswett> Something *really* weird, you say?
18:29:39 <hppavilion[1]> What's the weirdest data structure you serve here?
18:30:14 <tswett> The filesystem is a polynomial. You create a file by multiplying the polynomial by (x - a), for some constant a. You delete a file by dividing by (x - a).
18:30:33 <tswett> In order to get a list of all files, all you have to do is solve the polynomial.
18:31:55 <tswett> Ooh, and here's another idea.
18:31:59 <tswett> The "canyon filesystem".
18:32:04 <tswett> It's similar to the queue filesystem.

18:32:17 -!- Phantom_Hoover has joined.
18:32:55 <tswett> The canyon filesystem has two lines carrying analog signals, one for input and the other for output.
18:33:22 -!- callforjudgement has joined.
18:33:57 <tswett> When you put some input in, you eventually get the same input out, except—just like shouting into a canyon—echo and/or reverberation (and/or frequency filtering et/or cetera) are applied.

18:42:33 <hppavilion[1]> I suppose we could go for something less esoteric and just use a multidimensional Python-style array
18:44:58 <hppavilion[1]> You wouldn't need to name the file itself to access it
18:46:44 <hppavilion[1]> OR we could do some weird hybrid depending on level
18:47:04 <ais523> the problem with analog storage is that you can't do reshaping
18:47:10 <ais523> the only reason we use digital storage at all is that you can
18:47:27 <hppavilion[1]> C/Tableindex/Treelocation/1 for the front of the dequeue, 0 for the back/
18:48:31 <ais523> why do you care so much about making the path look like a Windows path (a modern one with forward slashes, at that)
18:49:13 <hppavilion[1]> Well because I don't feel it'd work very well if it doesn't have nesting
18:49:26 <hppavilion[1]> I'm just using the windows path because that's just syntax, not semantics

18:49:41 <InputUsername> Not using nesting would be fun and esoteric, right?

18:52:48 <ais523> why not have a tag-based filesystem? where you can tag a file with a number of tags, and search by tag
18:52:53 <hppavilion[1]> Also, we can't just use an array (associative or otherwise) for the filesys, as that wouldn't be soy enough
18:52:59 <ais523> a hierarchial filesysetm is a special case of that
18:53:31 <hppavilion[1]> But that would be very, VERY slow and inefficient on large filesystems
18:54:18 <hppavilion[1]> OK, what philosophy should we base the Filesystem after?
18:55:03 <int-e> . o O ( is there any use for copy on read semantics? )
18:55:36 <hppavilion[1]> Is that a question about the filesystem or some other project?
18:55:56 <hppavilion[1]> Because I'm having trouble understanding what that meant

22:04:30 <shachaf> oerjan: what are you snickering about
22:04:44 <tswett> I'm writing assembly, and I want to put A on the stack, then put B on the stack, then take A off the stack, then take B off the stack.
22:04:50 <shachaf> oerjan: is it time to go snicker-snack?
22:05:07 <tswett> Hungry? Eat a snicker-snack.
22:05:33 <shachaf> That's not a very woeful situation.
22:05:33 <HackEgo> A hand in the bush is better than a stoned bird.
22:07:04 <tswett> Specifically: I want to put all registers onto the stack, then change to a different stack, then put a couple more registers on the stack, then pop all the registers off the stack, then pop the desired registers off the stack...
22:07:09 <tswett> Come to think of it, it's obvious.
22:07:19 <tswett> I just need to put the registers I want to save into the appropriate location in the stack.
22:07:37 <shachaf> Are you implementing threads?
22:08:41 <shachaf> Userspace threads under amd64-linux-gnu?
22:09:00 <tswett> Nope, kernelspace threads under... nothing.
22:09:37 <shachaf> Here's the code I wrote, kind of: https://github.com/rethinkdb/rethinkdb/blob/next/src/arch/runtime/context_switching.cc
22:09:46 <shachaf> Looks like it's been heavily modified since then.
22:10:08 <shachaf> But kernelspace threads are harder.
22:10:31 <shachaf> Are you switching address spaces too or something?
22:12:04 <oerjan> shachaf: as usual when reading about that sound in wikipedia i end up completely confused about what the norwegian sj-sound is supposed to be.
22:14:19 <oerjan> i am starting to think sj and rs don't represent different sounds at all, at least in southeastern dialects
22:15:29 <oerjan> but i keep getting the impression that whoever adds the norwegian information to these articles isn't quite competent
22:17:03 <oerjan> anyway, the two articles you linked and the norwegian phonology article have three different suggestions.
22:17:10 -!- `^_^v has quit (Ping timeout: 240 seconds).
22:17:43 <shachaf> what about https://en.wikipedia.org/wiki/Sj-sound hth
22:17:59 <tswett> shachaf: nope, I'm pretty much only switching some registers.
22:18:23 <oerjan> that's swedish only. i've been training on pronouncing it, but it's definitely not a norwegian sound.
22:18:32 <shachaf> I can barely distinguish voiceless velar/uvular fricative.
22:19:25 <shachaf> For that matter, I often hear alveolar trill as uvular trill. :-(
22:19:46 <oerjan> i agree on the first but not the second
22:20:07 <shachaf> Sure, because you can pronounce alveolar trill.
22:20:36 <oerjan> well it's of course _usually_ a flap in norwegian...
22:21:00 <oerjan> but adding a few extra trills isn't that hard.
22:21:19 <oerjan> like a trill but just one :P
22:21:29 <shachaf> Sure, I think that's what Imean.
22:21:37 <shachaf> Modern Hebrew 'r' is usually voiced uvular fricative, I think.
22:25:03 <oerjan> i'd been assuming it was an alveolar flap/trill, probably by default
22:25:36 <shachaf> when did you have the occasion to make assumptions about this particular consonant
22:29:14 -!- spatterworthy has joined.
22:30:38 <oerjan> lessee, we learned some hebrew songs in school, which would of course be completely unreliable on this front. and then there's the eurovision song contest back in the day. i suppose i haven't really been paying attention enough to pick it up reliably.
22:31:31 <shachaf> i learned some hebrew songs in school too
22:31:42 <shachaf> don't know much about the eurovision, though

22:42:37 <oerjan> i suppose an uvular r would be logical for original yiddish-speaking communities, or something.

22:47:12 <boily> quinthellopiaaaaaaaaaghghghghfhrhghfhgiurhghghrgh :D
22:50:04 <tswett> So %esp points to the top thing on the stack, right? Then 4(%esp) would point to the fifth byte from the top, 8(%esp) to the ninth byte, and so on?
22:51:52 <tswett> No wait, (%esp) would refer to the top thing on the stack.

22:55:47 <Taneb> tswett, that would depend which way the stack is
22:55:54 * oerjan gives shachaf a spot of the saucepan ===\__/
22:56:05 <tswett> Well, this is x86. The stack is only ever one way, isn't it?
22:56:13 <fizzie> tswett: You can DIY if you really want.
22:56:14 <Taneb> I don't know x86, like, at all
22:56:19 <shachaf> esp is just a register like any other
22:56:21 <fizzie> But that's correct as far as the push/pop instructions go.
22:56:24 <tswett> The bottom of the stack has the highest addresses, the top has the lowest addresses.
22:56:24 <shachaf> as long as you don't use push/pop/call/ret/etc.
22:56:37 <tswett> shachaf: I'll make sure not to use push and pop and the like, then.
22:57:37 <boily> oerjan: those are unIPAifiable sounds. quintopia knows them.

22:58:50 <oerjan> shachaf: darn that's got to be the problem, i was imagining really snobby queen's english
22:59:47 <tswett> Can the FLAGS register be used in push and pop instructions just like any other register?
22:59:49 <oerjan> boily: the saucepan abides no rules
23:00:14 <fizzie> tswett: No, there's a separate instruction for it.
23:00:25 <fizzie> pushf/pushfd/pushfq in Intel parlance.
23:00:57 <fizzie> Well, maybe that's a "yes" from another point of view. Depends on how you define "just like".
23:01:34 <shachaf> tswett: x86 is scow, use x86-64 instead hth
23:02:04 <fizzie> Also: you can turn one out of the lods/stos instructions into a stack operation for a stack that's growing to either direction, but they're not conveniently pairable: both post-{inc,dec}rement, and they use different implicit registers.

23:20:15 -!- mauris has quit (Ping timeout: 265 seconds).
23:23:34 <Sgeo_> Most things inn Perl 6 are Any. Except Junctions. Anys and Junctions are Mu. I wonder if we could define our own non-Any that manipulates things around it when used as an argument the way junctions do
23:24:58 <Sgeo_> "My favorite suggestion in all of this was to make Perl 6 a pure functional language and introduce monads."

23:31:18 <coppro> I can't help but think of perl 6 as a giant joke any more
23:32:37 <coppro> "While one side believes that auto-threading repetition of sid effects will crash any database that interacts with Perl 6, the other side believes that requiring extra pragmas to unlock their full power will prevent junctions from curing cancer."
23:34:28 -!- Patashu has joined.
23:36:17 -!- hilquias has quit (Ping timeout: 244 seconds).
23:39:51 <boily> is there any non-homeopathically statistically significant user base for perl 6?
23:47:47 -!- variable has joined.
23:48:03 -!- variable has quit (Remote host closed the connection).
23:53:57 <oerjan> <tswett> Isn't there someone here that was working on a way of doing exact real computation of some kind? <-- rings a bell. some kind of continued fraction where the numbers were given by a polynomial?
23:54:20 <oerjan> so could do e.g. e and stuff
23:54:59 <oerjan> (and not just unbounded precision, but exact.)
23:55:20 <oerjan> but my memory of it is definitely not exact
