My friend is a surf geek, today it is snow 25m/s storm and he went surfing. Hope he shares some pictures so I can share with you later.
13 hours ago, by Johan Larsson

perhaps relevant
he did not want to share pictures with the world
 
@JohanLarsson Maybe it's safer than on the coast?
 
@JohanLarsson :(
 
That snow storm looks nasty.
 
@Cerberus how do you mean?
 
When you're riding the waves, you stay above the water.
When you're walking down the street and the water comes streaming in, however...
 
12:05 AM
ok
 
perhaps relevant
 
That's a relief.
 
Why does our new bar have a thin black strip on top and a wider brown strip below? Am I the only one who can see this?
 
@tchrist I hadn't noticed. now I can't not
2
 
because it's christmas
 
12:18 AM
it's not there was SO
 
@MattЭллен heh.
 
*at
 
where did that was come from?
I'm not taking responsibility. GCHQ have hacked my brain
 
from all the negations?
 
The black bar is a bit ugly.
 
12:21 AM
I’ve tried in two browsers: ours has two different colors!
 
it is very black but I like the functionality
 
@JohanLarsson No, it is not.
And I can prove it, but it will take me a moment.
 
it's the background of body set in the CSS. I think it overlaps on top of the topbar and is moved down 10px
 
@tchrist I can't see it.
 
in C# on Stack Overflow Chat, Oct 15 at 21:45, by drch
maybe you are black / yellow color blind
 
12:23 AM
@MattЭллен Maybe where to noscript notice goes?
 
@KitFox no, the background is deliberately moved down by 10px
I suppose it could be related to the noscript
 
when do we get the hats?
 
you can start earning the from the 16th
@KitFox oh, OK, yeah, that actually seems to make sense
 
what is a noscript?
 
Noscript is a Firefox add-on.
Makes your web safe.
It allows you to disable Javascript depending on the website.
It also prevents XSS and ABE attacks, and a couple more things.
 
12:39 AM
@cornbreadninja麵包忍者 Right there on my iPod.
 
@Cerberus ty
 
@JohanLarsson I use it and can recommend it, but with a caveat: if you don't have a whitelist, you'll have to add every a website every time you encounter one that doesn't worth without Javascript. That's annoying, even though it's just two mouse clicks.
You can probably find someone else's whitelist somewhere to import. Or I could give you mine, but it will have a ton of domains that you will never visit.
 
Ok, got it.
 
What's it?
 
@cornbreadninja麵包忍者 The "black" part is RGB=(50,48,47) and the "brown" part is RGB=(48,45,50).
 
12:50 AM
how did you use the colorpicker so slowly?
 
I had to go deal with the carpet people.
 
Haha, now, Johan, that's not very nice...
 
Wasn’t here.
 
ok sry
 
Funny, though.
Don't worry, I'm sure Tchrist didn't mind. Right?
Reg says such things a thousand times a day.
 
12:51 AM
I’m fine.
That exaggerates the size so you can see the cut-line.
The artifacts are because I saved the damn thing as a jpg; d’oh.
Call me picky, but I find the split-color a bug.
And I can’t stop seeing it.
Every. Single. Time.
 
I really have to focus to see it :)
 
Perhaps it’s your monitor.
@MattЭллен Can you find the bug in the CSS that accounts for the disparity? I hate looking through that stuff.
 
1:08 AM
Oh, I hadn't noticed!
Now that you mention it, I see it.
 
And as @MattЭллен observes on the starboard, that which has been seen cannot be unseen.
 
Yeah, I do see it too. The top color is #32312F and the bottom is #302D27. Looks like someone was trying to do a half-ass gradient, though I can't see where that is in the CSS. Too lazy to look very hard.
 
It doesn’t look very good.
I bet it is a mistake.
 
ignore it
 
@tchrist It is an example of what astigmatism can look like.
 
1:16 AM
Indeed?
 
Yeah.
I have astigmatism in one of my eyes, and uncorrected it causes a ghosted image overlapping another image. Slight but noticeable.
 
Same, but I only notice it in night driving.
 
I notice it in high-contrast situations.
 
Right. Traffic lights at night.
Hm, I see that the Reverend Richard Coles was on QI tonight; I bet that was(n’t) a fun name to’ve grown up with.
Oh for goodness’ sake, it appears to be yet another case of nominative determinism, like my contractor-guy named Mark Hammer:
Richard Coles (born 26 March 1962 Early life Coles was born in Northampton, England and educated at the independent Wellingborough School (where he was a choirboy) Musical career Coles had learned to play the saxophone, clarinet and keyboards and moved to London in 1980 where he played in theatre. which won the Grierson Award. Coles joined Bronski Beat on saxophone in 1983. In 1984 Somerville left Bronski Beat and he and Coles formed The Communards, who were together for just over three years and had three UK Top 10 hits, including the biggest-selling single of 1986 with a version of ...
> Coles is openly gay[15] and lives with his partner in a celibate relationship, in respect for the current rules within the Church of England.
So a kid named Dick Coles grows up to be a gay priest.
Too funny.
 
So what does nominal determinism do for Mike Hunt?
 
1:22 AM
Gender misassignment? :)
 
Possibly.
 
I wonder whether he has a pipe and a bowl, and fiddlers three.
> Coel Hen appears in the Harleian genealogies and the later pedigrees known as the Bonedd Gwŷr y Gogledd (The Descent of the Men of the North) at the head of several post-Roman royal families of the Hen Ogledd.[2] His line, collectively called the Coeling, included such noted figures as Urien, king of Rheged; Gwallog, perhaps king of Elmet; the brothers Gwrgi and Peredur; and Clydno Eiddin, king of Eidyn or Edinburgh.
> He was also considered to be the father-in-law of Cunedda, founder of Gwynedd in North Wales, by his daughter Gwawl.[4] The genealogies give him the epithet Godebog, meaning "Protector" or "Shelterer".[2] The poem Y Gododdin mentions some enmity between the "Sons of Godebog" and the heroes who fought for the Gododdin at the Battle of Catraeth.
Gee, why do I feel like I’m reading Sindarin? :)
 
Sheer Tolkienism is all.
 
1:48 AM
I've made a slightly smaller version of this.
 
@Robusto It’s because he used a lot of Welsh phonology in devising Sindarin, actually.
 
That's what I was alluding to.
 
Hi!
Only religious people have an obligation to give to charity - What would an atheist say about this quote?
 
He would shrug.
 
Gimme RGB or HSV or something.
Not “Radiant Orchid”.
Their displayed colors are all over the place.
They all look like lavender to me, not orchid.
 
1:59 AM
 
@tchrist Why on earth, nay, in the universe, are you reading that?
 
Hint Hint...
 
NPR report I just now heard, so I googled it.
 
@TimTimmy Uhh I'm sorry, I don't know what youmean.
 
@tchrist I goggled it too.
 
2:00 AM
It was hard to hear the color. Or at least, the color I heard wasn’t the color I googled.
 
@Cerberus What would an atheist say if only religious people gave to charity.
 
@tchrist #FF0099
 
Aye.
 
Pretty basic color to be "color of the year" though.
 
More R than B.
Despite the other samples.
 
2:02 AM
@tchrist Yummy lavender…
 
Um, no.
Lavender has more B than R.
 
Hey guys, do you know what the orange hex colour in this image is? Many thanks :)
 
Doesn’t matter: R&B always comes off well.
 
@TimTimmy I have no idea what you mean or what you want me to answer.
@TimTimmy E67A06
 
2:05 AM
#E5790E
 
Or is that not hexy enough.
 
It varies.
 
Hm.
 
I picked the centre of the apple.
 
2:06 AM
@Cerberus The question doesn’t matter anymore, but how did you know the hex colour – what colour picker do you use? Thanks
 
@Cerberus Ich auch.
 
@TimTimmy I use Colorette. I press alt-k anywhere in windows, hover over the right colour (the preview square shows you the colour under your cursor), then press the right mouse button, and the colour code is copied to clipboard.
@Robusto Then it must be the apple's fault, so fickle.
 
Apple betrays you at every turn.
 
Correct.
 
@Robusto Barely: in HSV, the H is only always 31° or 32°, whether you are in the apple or in the coil.
 
2:09 AM
@tchrist I mean the shade on this particular image varies.
 
I disavow all V knowledge in favor of H.
The H is pretty constant.
But the other two bits vary.
The S on top is 85, but on bottom only 75.
Your V or B bit flies all over the place, so we pretend not to notice it.
Actually, at the pixel level, there’s a bit of sharpening/gradient at the edges.
I really prefer to look at things in HSB because RGB usually tells me nothing.
Although the Radiant Orchid was obvious enough.
 
Well, the image is from a JPG so there can be artifacts all over the place. It's not just around the edges, though that is where the artifactory usually happens.
 
2:32 AM
I have no idea why they put so much empty space on the left of that image so that they could set the left edge to 50%, cutting all that space off. It must be a design-ey thing, but I can't fathom it. There would be no difference if they were to cut off the empty space and setting the left edge to 0. Except the browser wouldn't have to download a larger image.
And it's a JPG, so it's not like they don't have to pay for the empty space.
That said, I like what they did with it. A few marker strokes, a few Koh-i-noor Rapidograph lines, and hawt.
 
Takes talent to make something so simple stand out like that.
 
Yup.
That is the essence of Japanese calligraphy or sumi-e painting. It's all carelessly done, dash and splash, and what emerges is beautiful.
Hahaha, check out this high-res image: upload.wikimedia.org/wikipedia/commons/0/0c/Pine_Trees.jpg
I have very fast internet speed and that image is still building in a browser window.
I should say, "It's all seemingly carelessly done*. Apparent insouciance.
Still trying to render that image. Damn. It has to be humongous.
But check out the brushwork once you can see it! Wow. Worth the wait, definitely.
 
@Robusto That crashed Safari.
 
Haha. Revenge of the ink!

It's only 47 MB?
 
Yes.
Well MiB.
 
Ah, now I am able to save it to my hard drive.
 
Sure takes a long time to load -- in anything.
 
Complete!
That had to be over five minutes.
There's a detail from it. Check the brushwork.
Those artists worked for years to get that technique down.
 
I wonder why it’s so high-res.
 
2:51 AM
It's probably the size of a wall in real life.
 
I wonder why mine only took 1:48 and yours took 5m.
 
Did you download it directly or render it to the browser?
 
Direct download.
It crashed my browser.
Given its dimensions of 16723x7828, printed at 300 dpi, it would be about 56×26".
 
I didn't download it directly. I sent it to the browser window. Big mistake.
@tchrist I'm sure it's higher-res than 300 dpi.
 
What do you mean?
If you printed it at 600 dpi, it would be about 28×13".
 
2:56 AM
These chops are usually from a hand-held stamp.
Look what size they are in comparison to the rest of the picture.
 
Yes, but I don’t understand what you mean about higher res than 300 dpi.
 
I would bet the original is more like 8' x 16'.
@tchrist Brain cramp. I was calculating in the wrong direction.
Wow, I bet that is painted on silk.
 
If you know the size that such chops normally are, we could calculate the real size easily enough.
 
They vary. But I would guesstimate that those are the size of a person's hand, or fist.
 
That big?
 
2:59 AM
A seal, in an East Asian context, is a general name for printing stamps and impressions thereof which are used in lieu of signatures in personal documents, office paperwork, contracts, art, or any item requiring acknowledgment or authorship. China, Japan, Taiwan, and Korea currently use a mixture of seals and hand signatures, and increasingly, electronic signatures. Chinese seals are typically made of stone, sometimes of metals, wood, bamboo, plastic, or ivory, and are typically used with red ink or cinnabar paste (). The word 印 ("yìn" in Mandarin, "in" in Japanese and Korean, pronounc...
> In size, they are comparatively enormous, measuring 2 to 4 inches (5.1 to 10 cm) across.
My fist is roughly 4"x4" square.
 
Right.
You know, the border seems to be of a different material.
 
Maybe it's only the border that's silk. The equivalent of a frame, or matting.
No, that is the matting.
And it is in a lacquered frame.
 
That makes more sense.
 
Yeah. I didn't look closely at the edges before.
 
It probably makes more sense to look at it at 25 or 50% than at 100.
 
3:07 AM
BTW, the width of the frame would seem to indicate a gigantic size as well. Look how narrow it is compared to the piece itself. If it were only poster-sized the frame would be the width of a fingernail paring.
 
True.
 
Also, it's in pieces. Like screens, probably.
 
Easier to move.
Hm.
Would they really use a frame less than an inch wide?
If just the deep red laquered part is the actual frame.
And the square chop is a 4" square.
 
If the square chop is 4x4, then the frame is 2". And change.
 
Maybe about an inch. Hm.
So not just the outermost dark maroon then?
 
3:13 AM
@tchrist The dark outer part is the frame. The lighter inner part is the matting.
 
Well, there is a wide, less saturated maroon portion on the inside before it hits gold.
You think that is matting or frame?
 
And it definitely looks like the matting is silk, and tucked in where it meets the frame. Probably clamped against it.
 
Oh duh. Now I can see the frame properly.
The dark part is just "higher", and the washed-out/desaturated bit is still wood frame sloping in.
And I agree on the silk texture.
 
Red line indicates edge of frame.
 
@Robusto good good.
 
3:16 AM
Blue lines indicate the inner and outer edges of where the matting is glued to the paper.
 
Yes, from the red line right is all frame.
 
@tchrist Exactly.
 
I wasn’t thinking in three dimensions.
 
It happens.
 
it can happen to everyone eventually
 
3:18 AM
Can you even imagine the work that went into that piece. The framing alone would have been a prodigious undertaking.
@cornbreadninja麵包忍者 Yes.
 
Now I wonder how the shot was taken.
 
No kidding.
 
The highest resolution digital SLR is the Nikon D800, at 7,360 x 4,912.
Well, 35mm.
Medium format is bigger.
Barely.
More likely a trick — vertical stitching.
That or somebody scanned in an 8x10" positive original.
Well, or 4x5".
I’m talking film size, of course.
 
Right: they use a LF camera.
I think they are a 4x5" equivalent.
8x10" would require larger lenses.
 
3:25 AM
Yeah. Back when I was in advertising, 4x5 was the largest transparencies we usually worked with. Some photographers used the Hasselblad 2.5" (IIRC) format.
 
That was still pretty high-res.
 
Oh yes.
Trying to remember.
I think a 4x5 normally scans into something like 100 mp, and an 8x10 into 400 mp.
 
I wouldn't be surprised.
 
He’s making 274 Mbyte images in 16-bit color.
At 6000 x 8000 px.
 
3:30 AM
The ink painting is ~16000x8000 px.
 
So that’s two LF scans.
8000 on the long side, twice.
 
Yeah. Wouldn't surprise me if they cut it up.
And stitched it together.

This is actually pretty normal in giant landscape prints.
Hm.
That won’t work.
It would be 16k by 6k if done that way.
They have to have turned the axis and done more stitches.
In which case it might possibly have been a D800, which has a 7300 px long axis.
But those are damned tricky because of parallax issues.
You need a special tripod head that pivots on the exit pupil of the lens and good stitching software.
I prefer as few shots as possible, and two 4x5s stitched seems most likely, but I can’t make the numbers work.
That betterlight page in my Yup above is really quite interesting.
If I recall correctly, these things do not use Bayer interpolation at all. They scan each point in each of the three values.
Like a normal scanner does.
Ok, look at the bottom stuff. He can do wider panos without bad tricks.
A very modern wonder.
So this could have been done with one scan.
 
Interesting.
 
They’ll have put the 8k edge on the vertical and then used the pan to create the long edge.
 
3:42 AM
You would think there would be some vignetting from so large a lens.
 
Not sure about that.
Correction.
I’m sure there would not have been at those f-stops.
Landscape photographers never ever shoot at full aperture.
 
Ah.
 
And once you stop down the lens a bit, you would only get vignetting with bad equipment, like too many stacked filters or something.
He uses between f/8 and f/16 on his examples. There would never ever be vignetting with such small apertures.
If you shoot a fast lens wide open, you will often get some vignetting. Or a wide lens, especially.
Not that there are many fast wide lenses.
But even regular wides will do that.
 
Going in the other direction, a guy I knew who used to do bird photography used a parabolic reflective lens. I think it was like 1200mm or longer. But he could get amazing closeups. Very shallow depth of field. He had to shoot the bird from the side because if it was head-on, the beak would be in focus but the tail feathers would go soft.
 
Yes, I’ve seen those.
The problem with that sort of mirror lens is that the out-of-focus elements can get really weird, like toroids.
 
3:47 AM
Hmm. But I thought the parabolic mirror corrected all the chromatic and spherical aberration inherent in a refractive lens.
 
But they are many many times smaller and cheaper than regular lenses of the same focal length.
 
Also, because they're reflective, the lowest they go is like f8.
So you need a lotta light.
 
A catadioptric optical system is one where refraction and reflection are combined in an optical system, usually via lenses (dioptrics) and curved mirrors (catoptrics). Catadioptric combinations are used in focusing systems such as search lights, headlamps, early lighthouse focusing systems, optical telescopes, microscopes, and telephoto lenses. Other optical systems that use lenses and mirrors are also referred to as "catadioptric" such as surveillance catadioptric sensors. Early catadioptric systems Catadioptric combinations have been used in many early optical systems. In the 1820s, A...
Look at the prices and focal lengths on those mirror lenses, and you’ll see why.
The first link is good.
 
Yeah, good information.
> However, these situations are rare. For example the shots above were taken in a local bird zoo where you can get very close to your subject - in real life you'll most likely end up with situations like in the eagle picture (the 2nd picture) and therefore with unsteady background blur.
 
Exactly.
 
3:53 AM
I have to tell you, the guy I knew would spend hours creeping up on his prey. He had his camera mounted on a rifle stock and he had a camo poncho over him like a sniper. He would inch a long and get very close.
 
Sure, I’ve known those people.
 
I went with him one day and it was interesting for about the first hour or so. But it took him two hours to take his first shot.
 
If he is using a mirror, he wants to get close.
Correction: if he’s a birder, he wants to get close.
 
Yes.
 
No lens is ever long enough for birding. Ever.
Unless you have a remote setup.
My kittens would like me to come to bed with them.
 
3:55 AM
This guy had frickin' amazing eyes, though. He once grabbed my arm and pointed, saying, "Look, it's an ivory-billed woodpecker." I said, "Where?" He said, "Over by that stump." Me: "What stump?"
 
Naw.
Pileated.
Or else you were in Cuba.
 
I might be getting the name of the bird wrong. That was 40 years ago.
 
Oh, he might well have said it.
But still.
There are semi-constant reports of them.
 
When I was out with him that day I became the 6th person in the state of South Dakota to see a glossy ibis.
 
The best proof is actually audio.
Oh, if you were in SD it was certainly a pileated instead.
Still magnificent.
 
3:57 AM
The point is, he could see stuff with his eyes that I couldn't see with binoculars.
 
Well.
You get used to it.
 
We were driving along and he just about runs the car off the road, pointing: "Is that a Hudsonian godwit?"
 
My non-birder friends think I have freakish eyes, but I don’t. It’s something else.
 
Might have been a white-faced ibis. I can't remember which is the rare one now.
 
Ibides are generally hard to come by where I live now.
 
3:59 AM
> Most unusual are the sightings of Glossy Ibis. Total historic reports for the state are four, the same number said to be seen here in the past two weeks.
No, total historic reports are six, asshole.
 
Heh.
 
The reason our best proof is audio is because the ivory bill does a double-tap, the pileated only a single.
And we have recent double-tap recordings.
No good photos or video.
 
The guy I'm talking about is listed down at the bottom, in the part about his "love affair with birds and life" . . .
 
Ah.
The Ivory-billed Woodpecker (Campephilus principalis) is one of the largest woodpeckers in the world, at roughly 20 inches in length and 30 inches in wingspan. It was native to the virgin forests of the southeastern United States (along with a separate subspecies native to Cuba). Due to habitat destruction, and to a lesser extent hunting, its numbers have dwindled to the point where it is uncertain whether any remain, though there have been reports that it has been seen again. Almost no forests today can maintain an Ivory-billed Woodpecker population. The species is listed ...
The Pileated Woodpecker (Dryocopus pileatus) is a very large North American woodpecker, roughly crow-sized, inhabiting deciduous forests in eastern North America, the Great Lakes, the boreal forests of Canada, and parts of the Pacific coast. It is also the largest woodpecker in the United States, except the possibly extinct Ivory-billed Woodpecker. Description Adults are long, span across the wings and weigh , with an average weight of . Each wing measures , the tail measures , the bill is and the tarsus measures . They are mainly black with a red crest, and have a white line down th...

4:03 AM
Yeah. And he used to shoot them with a gun before painting their pictures.
 
The female IB has a black crest, which the P doesn’t.
He did.
I certainly delighted in seeing pileateds up in northern Wisconsin.
 
My stepdad’s mom has them come into her yard up there all the time. She’s 84, my last “grandma”. But Mom and he have been married for > 40 years.
 
That's the dude.
He was in his 50s when I was 20 or so.
 
"has consented"
 
4:05 AM
I know, right?
 
> The Ivory-billed Woodpecker is sometimes referred to as the Grail Bird, the Lord God Bird, or the Good God Bird, all based on the exclamations of awed onlookers.[9] Other nicknames for the bird are King of the Woodpeckers and Elvis in Feathers.[10]

The Story of Film: An Odyssey is a documentary series about the history of film, presented on television in 15 one-hour chapters with a total length of over 900 minutes. It was directed and narrated by Mark Cousins, a film critic from Northern Ireland, based on his 2004 book The Story of Film. The series was broadcast in September 2011 on More4, the digital television service of UK broadcaster Channel 4. The Story of Film was also featured in its entirety at the 2011 Toronto International Film Festival, and it was exhibited at the Museum of Modern Art in New York City in February 201...

Been watching this. It's very interesting.
I just wish it was in HD.
Available on Netflix. Streaming.
 
Interesting.
ibis [ˈaɪbɪs]. Pl. ibises; also (now rarely) ibides [ˈaɪbɪdiːz], ibes [ˈaɪbiːz].

Etymology: a. L. ībis (gen. ībis, ībidis, pl. ibēs), a. Gr. ἰ̆βις (gen. ἴβιδος, ἴβεως) the ibis, an Egyptian bird. So in Fr., Sp., and Pg.; Ital. ibi.
I guess they couldn’t decide whether it should be a Greek plural (ibides) or a Latin one (ibes), so settled on ibises. Probably just as well.
 
Just as well. Anyway, gotta snooze now. Laters.
 
Really. Night.
