00:04:24 <fizzie> SDL isn't exactly known for having much convenience code around the low-level API in the "core".
00:04:46 <pikhq_> This is a case of SDL not merely lacking convenience code.
00:04:56 <pikhq_> This is a case of SDL being *harder than the APIs it's wrapping*.

00:24:39 <fizzie> I would think the reasonable way to implement a synchronous sound API in SDL would be to build it on top of the asynchronous one, instead of trying to map those calls to something backend-specific that might not even exist, in which case it's pretty close to convenience code from the implementer's point of view.

09:33:05 <elliott> <lambdabot> fizzie said 12h 31m 19s ago: FWIW, the esocolors in L*a*b* are (138.4, -29.2, 30.6), (149.6, -17.9, 59.0), (143.8, -2.7, 38.9) and (135.5, 4.6, -12.0). http://zem.fi/~fis/esocolor.png shows the
09:33:05 <elliott> <lambdabot> slice of L*a*b* for L* = 141.8 (mean of those) that's representable in sRGB. The red dots are the colors' a* and b* coords.
09:33:25 <elliott> fizzie: That seems a reasonable enough range. How viable do you think your circle-in-L*a*b* idea would be?

10:39:29 <fizzie> elliott: I'm honestly not sure how much sense a circle makes, but here are some colors picked from one: http://zem.fi/~fis/esocolorlab.html
10:39:32 <fizzie> The first table has the original colors, and then colors at angles 0, 90, 180 and 270 degrees from the about-largest circle centered at the white point that can fit in sRGB for L* = min (second line) or mean (third line) of the originals. And then there's the same thing except with a rotating 'phase'.
10:39:37 <fizzie> Technically the "perceptual distance" between any horizontal neighbours in the "phase-wheel" tables should be identical, but YMMV -- it's only a rough approximation, after all.
10:39:42 <hagb4rd> i doesn't work perfectly yet
10:39:53 -!- MoALTz has quit (Ping timeout: 260 seconds).
10:40:42 <hagb4rd> but it _is_ perfect for long words..indeed
10:44:27 <elliott> fizzie: I don't quite understand the results, but they don't look promising. :(
10:45:08 -!- MoALTz_ has quit (Ping timeout: 260 seconds).
10:45:19 <elliott> I guess science is just not equipped to handle the task "give me four different pastel-looking colours that are perceptually evenly-spaced".
10:48:45 <fizzie> Not if you actually want colours you like, perhaps. I mean, those look more or less "pastel" to me, and as for even-spacedness, well... maybe not so much, but it's at least wrong in a justified way.
10:49:38 <fizzie> Anyway, you can't have more than three unique evenly spaced points in a two-dimensional space, which is what an equal-lightness slice of L*a*b* is.
10:50:20 <elliott> fizzie: Clearly we need a... four-dimensional colour tesseract.
10:50:49 <fizzie> I guess you could stick an arbitrarily oriented regular tetrahedron in the 3D L*a*b* space, but that's probably going to give nonsense out too.
10:51:05 <elliott> fizzie: Anyway, yes, they're pastel. But they're not "primary" in the way that the existing colours are; that is, the green, yellow and blue are a lot more *strongly* different than the ones the L*a*b* circle is spitting out.
10:54:02 -!- MoALTz has joined.
10:54:04 <fizzie> That much is true. Sadly, I could only have a so large radius for a "grayness-centered" circle before going outside sRGB. The existing points are more like on an ellipse in labspace.
10:54:08 <fizzie> For the record, the one black box (at 18 degrees for L* = 88.6) would be (1.000322, 0.831912, 0.837298) or "#100d4d6" in sRGB.
10:58:30 <elliott> Would it look horrible if you picked a circle outside sRGB and then "sampled it down" to sRGB?
10:59:02 <elliott> I mean, I've seen a circle thing with "all" of L*a*b* that mapped down the stuff outside sRGB.

11:05:58 -!- MoALTz has joined.
11:08:11 <fizzie> FWIW, I added the colors you get if you draw the ellipse that somewhat approximates the four original points (with major axis oriented along the esoyellow -> esoblue direction), and then pick points at the places where the major and minor axes cross the ellipse. But they're not especially pleasant colours either, especially the yellow after being brought down to the same level of "lightness as ...
11:08:17 <fizzie> ... defined by lab".

17:17:33 <elliott> fizzie: It has expanded since last time, I see.
17:17:55 <elliott> I suppose lightening them with L*a*b* would go as disastrously as the other Lab experiment?
17:18:21 <fizzie> I can try it, but I doubt it differs from HLS terribly much.
17:18:45 <elliott> 0.96 from the first table and 0.60/0.70 from the second table seem good.
17:19:52 <fizzie> For completeness, I added a third table that has equal-darkening values too.
17:20:06 <fizzie> Not that you probably need those.
17:20:19 <fizzie> Except for the GOTH EDITION the 0.1 values from that might work.
17:20:34 <elliott> fizzie: Well, it could be useful for Halloween, I suppose.
17:21:30 <elliott> fizzie: If I want to make the wiki DARK and SPOOKY.
17:22:05 <elliott> fizzie: I THINK YOU'LL FIND that orig = 1.00, unsurprisingly.
17:22:11 <elliott> Maybe you should remove the orig column and flip the table. :p
17:22:25 <elliott> And then rename the 1.00 column to orig. Clearly perfection is a requirement.
17:22:50 <fizzie> 1.0 column of second table is not the most useful either.
17:22:53 <elliott> In fact, you should completely automate the table-creation process.
17:23:10 <Sgeo> tswett, is it ok that I said hi?
17:23:51 <ais523> so what are these esocolor things?
17:24:55 <elliott> Sgeo: Saying hi is forbidden.
17:24:58 <elliott> ais523: We're painting fizzie's house.
17:25:09 <ais523> not sure I believe that
17:25:23 <elliott> Some people believe the world is round, man.
17:25:27 <elliott> fizzie: Housepainting, right?
17:25:40 <ais523> elliott: does anyone /really/ believe the world is piecewise-linear?
17:26:57 <elliott> ais523: Like, God, man.
17:27:25 <tswett> Sgeo: yep.
17:33:11 <Sgeo> Q: "What about Lunar Eclipses?"
17:33:11 <Sgeo> A: A celestial body, known as the antimoon, passes between the sun and moon. This projects a shadow upon the moon.
17:34:16 <nortti> Sgeo: where is that quote
17:34:22 <nortti> +from
17:34:29 <Sgeo> http://www.theflatearthsociety.org/wiki/index.php?title=FAQ
17:34:54 <elliott> i still haven't forgiven sgeo for saying hi
17:35:52 <nortti> oh god. the flat earth society
17:36:14 <fizzie> elliott: Just for completeness, L*a*b*-lightened/darkened versions: http://zem.fi/~fis/esocolor3.html
17:41:13 <fizzie> The differences are kinda-sorta slight. E.g. the 0.5 columns are identical for 10 of the 12 eight-bit components, and the remaining two differ by 1.
17:41:56 <elliott> fizzie: Well, the darkening table is rather different.
17:42:08 <elliott> (And rather better, I think.)
17:44:50 <elliott> I really need to replace that peach, though.
17:45:35 -!- hagb4rd2 has joined.
17:45:40 -!- hagb4rd has quit (Ping timeout: 246 seconds).
17:46:53 <fizzie> The darkening table is different because it's done differently; it's "equally spaced points on the line between the original and the nonchromatic black", so it sorta desaturates while it's at it. I added a third table that just brings L* down to 0, but those tend to again fall outside the vaguely shaped sRGB region.
17:49:18 <elliott> fizzie: L*a*b* is scaring me a bit. I mean, I know *I* can't imagine a colour not inside sRGB.
17:49:23 <elliott> Who is to say such colours even exist?
17:49:46 -!- ais523 has quit (Remote host closed the connection).
17:50:04 <fizzie> Any laser pointer light is outside sRGB, unless it happens to exactly coincide with one of the three sRGB primaries.
17:50:29 <fizzie> (I think.)
17:50:43 <elliott> But *who* can *tell*?
17:50:48 <elliott> This is the real question.
17:51:15 <olsner> elliott: you'll love this one: https://twitter.com/#!/jakedevine/status/182865434289258496/photo/1
17:51:30 <elliott> fizzie: http://upload.wikimedia.org/wikipedia/commons/6/60/Cie_Chart_with_sRGB_gamut_by_spigget.png -- see, sRGB can even depict areas outside of sRGB.
17:51:33 <Phantom_Hoover> fizzie, are the R, G and B in sRGB defined as precise wavelengths?
17:51:51 <elliott> olsner: that's amazing
17:52:10 <fizzie> elliott: They just do those fake-color images. You'll notice there's a discontinuity at the border of the sRGB triangle.
17:52:31 <elliott> fizzie: Shut up.
17:52:49 <elliott> fizzie: Next you'll tell me those nebulae don't *really* look that colourful.
17:53:20 <elliott> Phantom_Hoover: You forgot the s.
17:53:21 <fizzie> Phantom_Hoover: Well, they're defined in the XYZ colorspace. I suppose they're not exactly monochromatic.
17:53:48 <Phantom_Hoover> Defining colour spaces in terms of colour spaces.
17:53:50 <Phantom_Hoover> I like it.
17:54:04 <elliott> fizzie: Why do we even need colour spaces, man? Can't we just use wavelengths?!
17:54:11 <fizzie> I mean, they'd be at the borders of that chromaticity chart if they were.
17:54:13 <elliott> (Question more serious than I'd like.)
17:54:25 <Phantom_Hoover> elliott, because that prevents the display of purple.
17:54:25 <olsner> hmm, twitter had a fair bit of wtf itself there... the text in the tweet says "pic.twitter.com/ybRMIfeR", the status bar while hovering the link says "http://t.co/ybRMIfeR", the tooltip says "https://twitter.com/jakedevine/status/182865434289258496/photo/1"
17:54:34 <olsner> and finally, following the link takes you to the link I pasted above
17:54:55 <elliott> Phantom_Hoover: Well, as we all know, purple isn't real.
17:55:00 <elliott> Phantom_Hoover: So it doesn't matter if you can't display it.
17:55:11 <itidus20> lol
17:55:12 <elliott> Phantom_Hoover: OK, why can't we just use a combination of an arbitrary number of wavelengths?!
17:55:46 <fizzie> As soon as they start making displays that give out arbitrary spectral power distributions, I suppose we can.
17:56:01 <elliott> fizzie: The displays can just ignore the colours they can't produce!
17:56:10 <Phantom_Hoover> They had a thing in St Andrews which pulsed laser light at arbitrary frequencies.
17:56:15 <elliott> L*a*b* still exists and there aren't any displays with that! (Are there?)
17:56:43 <elliott> Phantom_Hoover: I forget, did I link you to that thing where you stare at an image and its border becomes more blue than blue itself.
17:56:46 <elliott> That thing is awesome.
17:56:46 <Phantom_Hoover> I suppose if you miniaturised the hell out of that and stuck a few of them behind each pixel, you could compound a few wavelengths (which is enough).
17:56:54 <Phantom_Hoover> elliott, it's green, not blue.
17:57:02 <elliott> Phantom_Hoover: No, there's a blue one.
17:57:18 <elliott> Phantom_Hoover: It's awesome.
17:57:23 <elliott> I really like the blue colour it produces.
17:57:44 <elliott> Phantom_Hoover: Grep /Eclipse of Mars/, http://www.skytopia.com/project/illusion/illusion.html
17:58:12 <fizzie> Alternatively, if you just hook the display up to the optical nerve (or I guess clamp it on the retina and add enough pixels) you can specify which color receptors to tickle, which is by definition enough to make any seeable colour for that person.
17:58:50 <Phantom_Hoover> elliott, the text accompanying it suggests that it's just not representable on a monitor.
17:58:51 <fizzie> I suppose if you aim *really well* you could do it from a distance, too.
17:59:26 <elliott> Phantom_Hoover: Uhh, the colour it produces is not representable on a monitor.
17:59:39 <elliott> It's an optical illusion; it doesn't have to have any pixels of the colour in question to make you see it.
17:59:44 <elliott> I have done it, it works perfectly.
18:00:06 <elliott> fizzie: Oh, CIE 1931 XYZ actually includes colours that don't exist. That's reassuring.
18:00:09 <elliott> I mean, aliens.
18:00:39 <Phantom_Hoover> elliott, I mean it suggests that it's not displayable by a monitor but can be realised through other non-illusory means.
18:00:51 <elliott> Phantom_Hoover: Oh, well right.
18:00:59 <elliott> Phantom_Hoover: It certainly looked more brilliant than any cyan *I've* seen.
18:01:51 <Phantom_Hoover> http://en.wikipedia.org/wiki/File:CIE_1931_XYZ_Color_Matching_Functions.svg
18:02:06 <Phantom_Hoover> WTF, red receptors are actually slightly purple?
18:02:23 <fizzie> The color matching function approximations are IIRC really horrible.
18:02:40 <fizzie> There are "better" curves in the bits that talk about the eye.
18:02:52 <fizzie> (Not that they're any more clearly "red" or "green" or "blue" either.)
18:03:21 <fizzie> http://en.wikipedia.org/wiki/File:Cone-response.svg has some sort of normalized curves.
18:03:30 <elliott> fizzie: Are there colourspaces that contain the entire visual range?
18:03:31 <fizzie> (Don't know how good those are either.)
18:04:16 <fizzie> elliott: Well, XYZ for one, as long as it's the visual range for the CIE standard observer.

18:04:35 -!- RocketJSquirrel_ has changed nick to RocketJSquirrel.
18:05:34 <elliott> fizzie: Man, fuck that standard observer.
18:05:47 <elliott> I suppose that's why everyone specifies things in terms of XYZ?
18:06:30 <fizzie> It's a reasonable thing as long as your target market is humans.
18:06:53 <elliott> Phantom_Hoover: Did you do that eclipse of mars thing yet it's awesome.
18:06:54 <fizzie> But obviously you can't represent an arbitrary spectrum with just three components, so it's not enough for more sophisticated customers.
18:07:02 <Phantom_Hoover> Yes, I did.
18:07:06 <elliott> fizzie: OK but what about aliens?
18:07:24 <elliott> fizzie: Or dogs. Is infrared in XYZ?
18:07:42 <fizzie> I suppose you'll just have to start modeling actual spectral power distributions. Some 3D modelling systems do.
18:08:08 <fizzie> That LuxRender thing, for example.
18:09:32 <fizzie> (Well, okay, they're still just sampled and quantized spectra.)
18:10:23 <elliott> fizzie: Or dogs. Is infrared in XYZ?
18:11:08 <fizzie> I think the XYZ color matching functions go to 0 pretty much at the edges of "visible light", so I'm going with no.
18:11:54 <elliott> Phantom_Hoover: http://www.skytopia.com/project/illusion/ipage-mb.html Does this one work for you? It doesn't work for me.
18:11:57 <fizzie> LuxRender has a fancy thing where if you specify a color in R, G, B, it has a whole thing -- http://www.cs.utah.edu/~bes/papers/color/ -- that it uses to make a "physically plausible" spectrum for it.
18:13:13 <Phantom_Hoover> elliott, works, I just need to change the point of focus a lot.
18:13:26 <elliott> Phantom_Hoover: Oh, wait, I think this might be a better version of the Eclipse of Mars: http://www.skytopia.com/project/illusion/ipage-et.html
18:13:28 <elliott> I think that's the one I used.

20:44:28 <elliott> That would be very helpful for my lifestyle.

20:44:39 <elliott> Well, it's just they're so kind. :(
20:44:53 <fizzie> And yes, there's also an older list of 10 such words from 2009.
20:45:03 <fizzie> This one is from 28 Feb 2012.
20:45:34 <nortti> fizzie: that older one is the list that I have read
20:45:56 <oerjan> elliott: i think so, but note that if you die between the sinning and erasing for a cardinal sin, you are _really_ screwed. and that doesn't even get into latae sententiae excommunication...
20:46:08 -!- MoALTz_ has joined.
20:47:16 <elliott> oerjan: I don't anticipate dying before this answer is accepted.
20:47:25 <oerjan> OKAY
20:47:45 <fizzie> oerjan: Can you just uncovert right before you intend to sin, and then reconvert just before the guilt-erasing?
20:48:18 <nortti> fizzie: It just came to mind when reading english language forums and seeing hiw english language doesn't have a good term for commafuckers
20:48:33 <elliott> nortti: "Grammar Nazi" is in widespread use.
20:48:51 <oerjan> fizzie: i think this stuff might require some element of genuine _regret_, you know.
20:48:52 -!- MoALTz has quit (Ping timeout: 244 seconds).
20:48:56 <elliott> Commafuckers is less distasteful, though. Although orthography ain'tn't grammar.
20:49:05 <elliott> oerjan: Wait, really?
20:49:07 <elliott> Fuck that, then.
20:49:16 <oerjan> elliott: always a catch.
20:49:20 <elliott> I mean, guilt, sure; regret, no.
20:49:26 <elliott> I'd do it again, and feel bad about it.
20:50:18 -!- hagb4rd has joined.
20:51:43 <elliott> Awesome, they did it, now I can erase the evidence.
20:51:45 <elliott> Or... or is that worse.
20:51:53 <oerjan> yes.
20:54:36 <elliott> oerjan: http://stackoverflow.com/questions/9830006/type-signature-between-funtion-and-class/9830084#9830084 will people look back on me in the future and think "wow that ehird guy is such an asshole"
20:54:39 <elliott> im guilt :'(

20:55:54 <elliott> when we're all dead
20:55:59 <elliott> what will the kangaroos think of me
20:56:48 -!- MoALTz has joined.
20:57:34 <elliott> get the feeling oerjan doesn't know much about kangaroo feelings
20:57:41 <oerjan> i don't expect the kangaroos to be most likely survivors, given that eutherians already wiped most marsupials from the _other_ continents, and humans have introduced eutherians to australia.
20:57:56 <elliott> ok but
20:57:58 <elliott> kangaroos are pretty tough
20:58:09 <elliott> and australia is devoid of almost all civilisation
20:58:11 <oerjan> could be.
20:58:11 <elliott> so
20:58:17 <elliott> you're totally wrong
20:59:27 <elliott> TIL humans have a conservation status
20:59:33 <elliott> wonder how long it took to decide that one

21:01:09 <oerjan> let me guess, "least concern, unless they destroy themselves"
21:04:09 <elliott> They should double the scale to account for species with worryingly high populations.
21:04:24 <elliott> Extinction to Grey goo.
21:05:41 <RocketJSquirrel> Also, that filename is wrong.
21:05:49 <RocketJSquirrel> The species name is "Homo sapiens", not "Homo Sapien"
21:06:54 <elliott> RocketJSquirrel: Homo sapiens is, like, plural, man!
21:07:00 <RocketJSquirrel> Nope!

21:57:26 <ais523> btw, that gzip file that got mangled by phpBB? the person sent me the original, it was a standard gzip file after all
21:58:04 <ais523> it had a lot of NULs after the first three bytes, which presumably phpBB deleted, which is why we couldn't parse it from that
21:58:58 <fizzie> Funny, you'd think at least the modification time would have survived.
21:59:14 <fizzie> Or was that zeros too?
21:59:31 <ais523> the zeros came very early
21:59:34 <ais523> so they'd have shifted all the bytes from then on out of place
21:59:45 -!- elliott has quit (Ping timeout: 264 seconds).
22:00:09 <fizzie> But it's the "fixed" three bytes, then a flag byte that might well be a 0, and immediately after that the mtime.
22:00:44 <fizzie> I think we looked for the mtime field under the assumption that a '\0' FLG byte would've been there, but got dropped.
22:01:18 <fizzie> I suppose it's not too rare to not have a timestamp there.
22:01:51 <fizzie> The "delete nuls" is not a very invertible operation anyway, so it's a bit of a moot point.
22:05:32 -!- Phantom_Hoover has joined.
22:05:51 <ais523> oh, mtime was indeed 0, in that case
22:06:03 <fizzie> Speaking of binary data, I've been cleaning my ~, and there's a 81098752-byte file called "ut.end" in there, and I haven't managed to distinguish it from random data yet. 'file' says just "data", 'strings' or hexdump don't seem to reveal any obvious patterns in the first few hundred kb, and a "forensics" proggie called "foremost" I had (that I ran on a broken-disk image) managed to extract ...
22:06:09 <fizzie> ... nothing from it.
22:06:17 <fizzie> I'm debating whether I should just delete it, or keep it secret, keep it safe.
22:06:27 <fizzie> On the other hand, 80 megs is quite a bit.
22:06:43 <fizzie> Not in the "it uses a lot of space" sense, more in the "there could be some stuff there" sense.
22:08:09 <fizzie> There's a single human-readable string I've seen in the 'strings' output, and it's the word "JUNK", the last thing 'strings' outputs.
22:08:14 <fizzie> That might be some sort of a sign.
22:09:00 <fizzie> Also there's an obviously regular-looking feature at the end, but I'm not sure what it is. It looks slightly like a sorted array of 8-byte integers.
22:09:09 <fizzie> I guess it could be offsets.
22:09:55 <fizzie> Or *something. They're a bit too large to be offsets to this file, but maybe only part of them is offsets.
22:11:21 <fizzie> The bit that actually looks like an incrementing counter goes up to 722559503.
22:11:43 <fizzie> Since the file extension is ".end", it could be just the latter piece of a CD image or something.
22:12:12 <fizzie> (Or some other 700-meg file.)
22:14:33 -!- MoALTz__ has joined.
22:15:04 <oerjan> clearly when that file is deciphered, the world ends. or is that when it is deleted.

22:20:41 <itidus21> ISBN 978-0- 8109-8752-4 Hello Kitty Everywhere!: Haiku: Postcards in a Hinged Box
22:21:19 <fizzie> I was kinda-sorta wondering that it had a weird number of digits for an ISBN.
22:26:45 <fizzie> That's a funny normalization, xn = sgn(x)*log(1+abs(x)). It's like some sort of symmetric logarithm thing.
22:27:27 <fizzie> Looks nice and smooth, though.
