@El'endiaStarman I get that that's an average, sure. It just doesn't match my internal definition of average. It's like asking for the square root of 25 and getting -5 as the answer. It's technically a square root of 25, but ewwww...

Render a Polygram code-golf graphical-output geometry I will flesh this out some more tomorrow. Given the number of vertices n ≥ 3 and the "step size" 1 ≤ m < n/2 (indicating the distance between two connected vertices), output a graphical representation of the corresponding regular polygram....

@Geobits Ha, yeah. I didn't have so much of a problem with it because I did this exact thing in Blitz 2D at least a year ago.

I try to keep my angles positive anyway. -90 is a bastard way of saying 270 in my POV ;)

In the context of a cellular automata where each cell's angle is updated to be the average of its eight neighbors' angles (then this is displayed as color).

Martin Büttner

@Geobits You'd rather take three left turns instead of a single right turn? ;)

@MartinBüttner Swap "left" and "right". :P

9:34 PM

I worked on aircraft for a long time. You'd say "come around to 270 degrees", or even "turn 15 degrees left", but never ever "turn -15 degrees".

Martin Büttner

@El'endiaStarman in my coordinate systems, positive angles tend to be measured to the left of the positive x-axis ;)

@MartinBüttner ....right. I was looking at it from the opposite direction.

Not sure why.

Y?

As in, measuring from Y?

Oh, I think it's because if you tell someone to take a 90-degree turn, they will be more likely to assume to the right.

I make no such assumptions

9:37 PM

I'll be left out

When you assume, you make an ass out of u and me.

@trichoplax What are your opinions about allowing the competing programs to create files / access the internet?

@PhiNotPi Entrants should be able to ask questions on Stack Overflow and troll chat.

9:39 PM

^ there

@PhiNotPi I don't see a problem with creating files. Whether you give them access to the internet will depend on whether you want them to base their predictions purely on the price history you provide, or on news activity and variance between rival pricing sites

@PhiNotPi Also, "access to the internet" allows for human input. Disallowing the internet seems the easiest way to preclude this.

I don't think internet access will be a good idea.

@PhiNotPi Entrants should be able to ask question on an SE site which gets migrated to a different SE site and then eventually closed as off-topic only to be resurrected by a different user in sandbox. This different user is your opponent KOTH bot

My school has its Homecoming dance next week, and there's someone in mind I want to ask. But I don't want to ask her the normal way. I want to send her a program that prints "Rachel, will you go to Homecoming with me?" However, if I just send her print"Rachel, will you go to Homecoming with me?",...

@NewMainPosts How do we feel about obfuscation challenges nowadays?

"The winner will be the program that it think looks the most obfuscated" is not an objective win condition.

If it was a popcon it would be a rough dupe of obfuscated hello world.

Lets see how long this one is

@Optimizer please stop it!

9:55 PM

"The fewest repeated characters with no literals" would be better.

It's like a popcon, just a little less objective

@Optimizer It was 5 again for me

@flawr post a plane crash next time!

@trichoplax yeah, there seems to be a limit of some sorts, it had 499 going down characters.

@trichoplax There's no objectivity at all to it. The winner isn't determined by votes, it's whichever the OP deems most obfuscated.

@AlexA. That's what I meant - even less objective that a popcon :)

Oh, haha. Okay.

9:59 PM

how fast can people see stereo scopic images/text?

@Optimizer If the horizontal separation is friendly, in a few seconds

I think it varies a lot between different people though

My eyes are optimised for manual refocusing rather than vision

what about images?

(no horizontal separation in that case)

AppleScript answer is the only one still up. XD

@Optimizer Do you mean 2 images side by side? Or the repeat pattern magic eye images?

I'm so proud of me. Or it means I'm wrong. >.>

10:08 PM

@trichoplax stereoscopic images..

wait.. its a broader category..

@Optimizer I assumed you meant two photographs, one for each eye, and both printed side by side. With a stereogram viewer it takes no longer than looking at a real scene. With two images side by side and manually adjusting your focus, it can take a few seconds to a few minutes depending on the person

I posted what I meant

I see a protruding P and T, after a few seconds

hmm

If you just take 2 photos, one from the position of each eye, you can display them side by side and look at one with each eye to see the image in 3D. Depending on how difficult that turns out to be, you may need to put a piece of card in between to block the view of the other eye, or possibly look through 2 tubes. Alternatively you can use a stereogram viewer which has mirrors so your eyes don't need to look in unconventional directions

If you are doing it with just plain images with no equipment, you'll need to keep the images small and close together or your eyes won't be able to look at them separately

@Optimizer This one is quite effective, but you'll need to shrink your browser window down until the centres of the two flowers are closer together than your eyes are, otherwise it won't work

onebox doesn't work: commons.wikimedia.org/wiki/…

(this will show the flower in 3d, rather than a hidden image like the one you posted)

@Optimizer Note that there are two different types of stereogram - one with the left eye's view on the left, and the other with the left eye's view on the right.

10:21 PM

you know you can put your finger halfway through the distance and focus on it for the flower to appear in 3d in the background automatically

PS, no need to give so much details. I know how to do it.

@El'endiaStarman How many degrees off is the second picture? o-o

The one I posted has the left eye's view on the left, and you need to let your eyes diverge (look behind the image). They also have the flipped version available, which will work with your method

@Optimizer Wait - your method works for diverging too. Nice :)

@trichoplax I know, because its not that 3d to notice whether the inversion is opposite :P

10:24 PM

Converging simply reverses the depth information of diverging.

Yes, and it looks horrible :)

Agreed. :)

Most stereoscopic images are made for divergence.

I find divergence much more comfortable for my eyes

Same.

@Optimizer No I actually mean your method helps me to use the diverging technique almost instantly rather than after a few seconds - so I see correct depth information without a delay

10:28 PM

@trichoplax I re-wrote my examples: meta.codegolf.stackexchange.com/a/7171/2867

@trichoplax i don't know how to put my finger behind the screen and still try to focus on it

@Optimizer Focusing on your finger would give the cross eyed technique. But just holding your finger there blocks the view to the image you are not meant to be looking at with each eye, so then looking through the image is much easier as the distracting other image is occluded

@PhiNotPi That seems significantly clearer now

@PhiNotPi I like that you score by product instead of sum. Seems like this will reward consistent behaviour rather than risky strategies that only occasionally do well.

The product is more realistic, anyways.

Do you think 1 round per hour is fast enough?

10:44 PM

Another method to view stereoscopic images easily is to focus on the reflection of something behind you.

Has anyone ever heard of "eye dominance?" I'm not sure it actually exists.

I don't think I've actually heard the term, but that sounds like the idea that if you see two conflicting images with your eyes, the one seen by the dominant eye will...uh...dominate what you see.

Which I don't think is far fetched.

And no, I don't mean the Pokémon.

Let your eyes diverge (or converge) until the blue and yellow rectangles overlap. Now what color do you see?

Also, the bottom part is a checkerboard of blue and yellow. (Click on the image to see this.) Note that it's not gray!

11:07 PM

@El'endiaStarman Both converging and diverging I see yellow slightly stronger, although I can flip between them at will (but not settle easily on a combination). This suggests both my eyes take precedence when seeing yellow, rather than one eye having dominance over the other. I have no idea whether that's typical

Actually it could just be the gamma of my screen - when viewed full size the checkerboard no longer looks mid grey - it's significantly lighter. So maybe everyone will see the yellow stronger on such a screen

Hm, just decompiled a random PE32 from the .NET 4.X framework and discovered 42 gotos in one C# method...

@El'endiaStarman I have more where that came from. Though less mind-blowing.

@minxomat ....eeewwww...

I have only ever used GOTOs in TI-BASIC...

And a line of C# that consists of 13 nested function calls. Someone should show Microsoft a style guide :D

@trichoplax Well, yellow is brighter, period. Our eyes will see it more easily in pretty much all circumstances.

So it really is C-hash rather than C-sharp

11:13 PM

@minxomat Not Microsoft. The programmer(s) that wrote that.

And slap their supervisors/interviewers too.

@El'endiaStarman Hmm. I wonder if green/magenta would be closer balanced

It would probably look awful.

Aesthetically, yes, but I mean maybe the brightness discrepancy might be less

yeah

Can't find the program I used to generate that right away.

Actually I doubt any combination of two of RGB against the remaining one would balance. You'd probably need to calculate the opposing colours specifically to have the same perceived brightness, and I don't know how much/whether that varies from person to person...

11:20 PM

Well, it's known that RGB is not an..."absolute"(?) color space.

Indeed

There are color spaces where brightness is uniform.

Or rather, known.

Hmm, not sure what the right terminology is. It has "L*" in the name, I think.

Lab?

L*a*b*?

Yeah!

Lab color space

A Lab color space is a color-opponent space with dimension L for lightness and a and b for the color-opponent dimensions, based on nonlinearly compressed (e.g. CIE XYZ color space) coordinates. The terminology originates from the three dimensions of the Hunter 1948 color space, which are L, a, and b. However, Lab is now more often used as an informal abbreviation for the L-a-b representation of the CIE 1976 color space (or CIELAB, described below). The difference between the original Hunter and CIE color coordinates is that the CIE coordinates are based on a cube root transformation of the color...

Forgot I can't use *'s...

11:31 PM

Hey, I should be able to use yellow and cyan!

...had a VERY unexpected result.

@trichoplax I see something similar to this. The middle area is made of up blue and yellow patches, although I can focus on one color or the other.

The way I've heard eye dominance explained is "one eye determines position (of the object in you 2D visual field) while the other eye determines distance"

My eyes make that a gradient. I think someone set the blend mode wrong.

@Geobits Zoom in. Way in.

Unless you're not talking about the checkerboard...

No, I mean the top part.

When converging

11:38 PM

Ah, gotcha.

Yea, I get the same thing there. It's terribly ugly :D

@trichoplax ^^ Just for you.

And I've heard that a way to determine dominance is to 1) Make a small triangular hole with your hands at arms' length. 2) Look at some object in the distance through the hole. 3) Bring the hole closer to your face, while still looking at the object. 4) Your hands will move to your dominant eye.

With the blue/yell and green/purple, I see splotches of the two colors. With the cyan/yellow, I sometime see splotches but sometimes see a greenish mixture.

Mine is a shifting gradient. My brain knows it's two separate colors, but it can't seem to figure out what to do with them :)

This may be why I fail depth perception tests, yet have otherwise perfect vision.

I have no problem with depth, but I still see a shifting gradient.

It's fun to watch, I think.

11:47 PM

I don't think I have depth issues, but doctors tell me otherwise. Makes me wonder what other people see that I don't. Seems to me I can discern depth just fine.

I've never had any problems with 3D or other stereoscopic stuff, so I dunno.

Weird. How exactly do they do depth perception tests?

The ones I've done were with a scope. One view for each eye, and it's a grid of circles. The objective is to call out which circles are "raised".

Basically slides on a lit background.

ahh, interesting

Do you like to watch movies in 3D if you can?

Meh. A couple were okay, but on the whole it's not worth the hassle of the glasses :)
