Talk:1814: Color Pattern

This link, note 1, may help whomever is going to be editing the comic explanation, I don't have time this morning. [1] Seebert (talk) 13:40, 22 March 2017 (UTC)

May help whoever is going to be editing ...

I can't be the only one for whom the note emoji are not showing up.

I don't see them either. I'm running Chrome 48 Portable. 162.158.62.225 14:18, 22 March 2017 (UTC)

Running Chrome 57, Chromium 53, and Firefox 52; the note emoji doesn't work on any of these (Linux Mint 17.3 64-bit). I wonder why? Cosmogoblin (talk) 15:19, 22 March 2017 (UTC)

Works for me, Firefox 52. Bring up the menu bar (Alt or F10), "View > Text Encoding > Unicode". If you still don't see the notes, it may be an issue with the font settings. You could try to fiddle with "Tools > Options > Content > Default Font". Instead of using the menu, you can bring up "Options" by entering "about:preferences" in the address bar. If that doesn't work, you need professional help. ;) 162.158.114.106 06:23, 23 March 2017 (UTC)

Firefox 71 on macOS and they still don't show up. Instead of the music notes, it says "♫ When the spacing is tight / And the difference is slight / That's a moiré ♫", with completely broken symbols at the start and end. Numbermaniac (talk) 05:07, 4 January 2020 (UTC)

Chrome 56 for Android, they display for me. Mikemk (talk) 10:24, 23 March 2017 (UTC)

AFAIK moiree patterns would not show up on an image that have been *properly* sampled, such moiree patterns are IIRC a byproduct of poorly sampled digital images. See WP for "aliasing" and "digital sampling" for reference. My two cents... Todor (talk) 14:31, 22 March 2017 (UTC)

Good Lord. 24 hours! If any of you guys are actual engineers you should be ashamed of yourselves! I am not an engineer, but I do know a a tiny bit about signal theory, hence the tip. But then again this just shows how cheap shit chinese gizmos proliferate. Quality just cost too much, haha! Just need the looks, not the brainz! Only the zombies loves them BRAINZZZZZ! hurr hurr. Todor (talk) 19:17, 22 March 2017 (UTC)

What are you trying to say with 24 hours. At this moment the comic has been up for 6 hours... If you think the explanation could be improved this is luckily a wiki, so you could just improve instead of rant ;-) --Kynde (talk) 19:55, 22 March 2017 (UTC)

Did I say that too early? Well it certainly is 24+ hours now and you guys still don't know where the dart target is. :D The comic suggests some matches of geometry in the digital age are highly prone to distortions. That's interesting in it's own, but feel free to ignore it. As I hinted the real issue here relates to digital sampling and aliasing problems related to this. There are more than one way to fix artifacts in images, but one method involves oversampling at about twice the nyquist frequency and running the signal through a band-pass filter. That's fairly common, but I think that will only solve aliasing related to sampling not moiree patterns occurring naturally due to geometry. I suspect a digital photo of a digital screen might be one such case, of "naturally" occurring distortion patterns. Todor (talk) 18:08, 23 March 2017 (UTC)

I cannot see this has anything to do with the explanation. Cueball has a moiré pattern on his picture of his lap top screen as taken by the phone, which obviously do not sample properly. I have seen the same using my phone and camera. This comic explains in a song why a moiré patterns forms, and the explanation above explains why such a pattern occurs. I cannot see any connection with what you write. But if you think it is relevant feel free to try and include a paragraph on the subject, it is a wiki. In case it does make sense, then it is probably just me that do not understand what you write, but hey I'm not an engineer so... ;-) --Kynde (talk) 09:51, 24 March 2017 (UTC)

The Dean Martin version, which likely is the only version anyone younger than I has heard goes like this- When the moon hits your eye - like a bigga pizza pie - That's amore - - When the world seems to shine - like you've had too much wine - That's amore ExternalMonolog (talk) 04:25, 23 March 2017 (UTC)

At first I thought Russell was alluding to Tom Lehrer's "That's Mathematics". :D 162.158.114.106 06:23, 23 March 2017 (UTC)

"Amore" is pronounces as /aˈmɔːrɛ/ in Italian. The initial vowel is a clean open "a" and there's no final "ei" but rather a clean open "e". Source: https://en.wikipedia.org/wiki/Help:IPA_for_Italian (Not counting I am Italian myself!)

Sorry, I can't help myself, but... If it's swimming in the sea and it's long and slippery, that's a moray 141.101.107.150 07:54, 23 March 2017 (UTC)

"When you try write a song, but the rhythm is wrong, that's a pity... (but still witty)" ^_^ 141.101.107.180 10:28, 23 March 2017 (UTC)

When it's sometimes quite slow but on average it goes, that's amor...tized

If a diet's your wish, but you can't avoid the dish, that's a moreish 141.101.107.150 12:10, 23 March 2017 (UTC)

Is it bad I came to the talk page specifically for more song lyrics? 172.68.65.30 05:29, 24 March 2017 (UTC)

Then you'll be happy to hear that Jamie Zawinski and Michael Bayne wrote another verse for their Moiré screensaver:

When the lines on the screen

Make more lines in between,

That's a moiré! 162.158.91.167 07:18, 24 March 2017 (UTC)

Now I'm happy ;-) I have also added this to the list of songs that precedes Randall's. Wonder if he knew about this, or got the idea by himself independently? I think (and hope) he did. He has before given credit on xkcd to one that had made a similar joke to his before him. --Kynde (talk) 09:51, 24 March 2017 (UTC)

"When you've stopped for the night,"

"and the dock's not in sight,"

"That's a mooring!"

"And there's nothing to do"

"That's a mooring!"

Does anybody else think that the title text may just as well refer to "amore" as to "a moire"? 162.158.91.209 15:40, 23 March 2017 (UTC)

Yes I think that is relevant. Have added it to the title text explanation. Thanks. --Kynde (talk) 09:51, 24 March 2017 (UTC)

Hmmm... the explanation would also be valid the other way round. Cause (amore) and effect (tight spacing) ... 162.158.91.209 11:15, 24 March 2017 (UTC)

"When an eel bites your toe, and he just won't let go, that's a moray..." KieferSkunk (talk) 01:21, 25 March 2017 (UTC)

Spider Robinson either invented most of this or at least used it in The Callahan Touch (1993)

Referring to the fabric weave, but still:

"When two patterns combine

In a way serpentine

That's a moiré"
