Osias:

Firefox users with HTTPS Everywhere may have trouble seeing the comic, and Chrome users may experience lag (for lack of a better word) when zooming in. [[Special:Contributions/141.101.99.168|141.101.99.168]] 06:11, 3 September 2014 (UTC)

The combination of "turtle" and "pixel" reminded me of how to code graphics in the older days with for instance turbo pascal (http://en.wikipedia.org/wiki/Turtle_graphics) - Stian

Would it be possible to have a "gallery" of all the zoom-in images? [[Special:Contributions/199.27.128.209|199.27.128.209]] 06:29, 3 September 2014 (UTC)

Since the Zoom-in images have at lest one story line in them (I read one about a book launch, the book was launched to space in a rocket), I think a gallery or some such is needed for them. [[Special:Contributions/108.162.250.218|108.162.250.218]] 06:50, 3 September 2014 (UTC)

I got to a white panel and there was nothing. Everything was white and zooming in or out didn't change it. Not sure if it was a bug or intended. -- [[User:Irino|Irino]] ([[User talk:Irino|talk]]) 07:15, 3 September 2014 (UTC)
* That happens to me when I click on the image in Chrome. Not sure why. [[User:Castriff|Jimmy C]] ([[User talk:Castriff|talk]]) 21:35, 3 September 2014 (UTC)

Yet another comic that doesn't work well on mobile. I'll probably compile a list of comics that are broken in some way for mobile... Er. Soon-ish. -RTR [[Special:Contributions/108.162.246.232|108.162.246.232]] 07:45, 3 September 2014 (UTC)

I have acquired a list of images with what they zoom into, and am working on turning that into something presentable. There's a lot of images though, so it may take a day. As for the white panel, yes, there does seem to be one broken link (out of nearly 500). I'm not sure how I would go about reporting it to get it fixed. [[User:Tahg|Tahg]] ([[User talk:Tahg|talk]]) 07:57, 3 September 2014 (UTC)

There are 79 different images. I have them isolated and am uploading them now. [[User:Omixorp|Omixorp]] ([[User talk:Omixorp|talk]]) 08:16, 3 September 2014 (UTC)
:Cool - the images are here - if you click on the broken links they can be seen. But why are they not visible? They take up a lot of space, so I have moved them to a separate gallery page as has been done with [[1350: Lorenz]]. [[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 11:44, 3 September 2014 (UTC)

Doesn't work at all (blank) on my Firefox and IE11. I just installed Opera and it works but it's VERY laggy. Also, I have to scroll UP to zoom in, not down. --[[Special:Contributions/141.101.97.206|141.101.97.206]] 08:25, 3 September 2014 (UTC)
:Neither on Firefox 31.0. Zooming until the first level of pictures, I see them appearing. But when they are larger than ~20 pixels they start to disappear. They only reappear intermittently when I pan or zoom. When I zoom in further, only images on the left side appear intermittently. This shows the grid is built from left to right, then top to bottom, and it just stops randomly. --[[User:Zom-B|Zom-B]] ([[User talk:Zom-B|talk]]) 20:32, 3 September 2014 (UTC)
:I'm having different problems with both Firefox 31.0 and 32.0 on Windows. When zooming in, all pixels (including white parts of the image) resolve to images with black background, so I never see the "white" ones (except for the initial "turtles" one). Anyone having the same problem? IE11 works for me. [[Special:Contributions/141.101.99.186|141.101.99.186]] 21:52, 3 September 2014 (UTC)

This date of this comic (Sept 3rd 2014) coincided with the date of Randall's book, What-If. This book is shown or referenced in a number of the frames.--[[User:Pudder|Pudder]] ([[User talk:Pudder|talk]]) 09:57, 3 September 2014 (UTC)
:But the site says the book was out September 2nd... [[Special:Contributions/108.162.237.161|108.162.237.161]] 11:21, 3 September 2014 (UTC)

Also just isolated the images. I described the procedure on my blog: http://azttm.wordpress.com/2014/09/03/xkcd-com-1416-pixels/ [[User:Azt|Azt]] ([[User talk:Azt|Azt]]) 09:58, 3 September 2014 (UTC)

I zoom in when I scroll up. I also like turtles. [[Special:Contributions/103.22.201.120|103.22.201.120]] 09:15, 3 September 2014 (UTC)

I think this comic might be a reference to D. Hofstadter's celebrated book ''Gödel, Escher, Bach'', what with the 'holism', 'reductionism' and 'Mu' coming out at some point (there is the very same construction in one of the dialogs from that book). Plus, generally speaking, ''GEB'' is all about "strange loops" and infinite recursions. --[[Special:Contributions/108.162.254.30|108.162.254.30]] 09:50, 3 September 2014 (UTC)

I have uploaded a graph showing the layout of the entire storyline, with thumbnails of the individual images, at [[Media:1416_Pixels_layout.png]]. --[[User:Mnw21cam|Mnw21cam]] ([[User talk:Mnw21cam|talk]]) 12:20, 3 September 2014 (UTC)

Has any attempt been made to find "extra" panels that may occur as a part of a logical series? For example, there is "chess-b" and "chess-w", are there "chess-a", "chess-c", "chess-d", etc? [[User:Jarod997|Jarod997]] ([[User talk:Jarod997|talk]]) 13:56, 3 September 2014 (UTC)

In an infinite series of turtles, at least 4 of them have to be youthful, genetically modified, and skilled in martial arts. Has anyone found them? [[User:DivePeak|DivePeak]] ([[User talk:DivePeak|talk]]) 21:30, 3 September 2014 (UTC)

I am on Chrome, and I cannot see any of the images in the Explain XKCD gallery even though the actual strip works fine. Anyone know what's wrong? [[User:Castriff|Jimmy C]] ([[User talk:Castriff|talk]]) 21:35, 3 September 2014 (UTC)

I don't know why the article says that the comic doesn't work in Safari on Mac OS X. It's working just fine here on Safari 7.0.6. I think if someone is going to make such claims, they should be careful to note which version of the software they're working with so others can compare appropriately.

== Adjacency list for the graph ==

I've created a quick hack to show what each image can contain [http://uber5001.github.io/turtles/ here]. Might be helpful in finishing off this page. [[User:Uber5001|Uber5001]] ([[User talk:Uber5001|talk]]) 22:48, 3 September 2014 (UTC)

Is the way the images are repeated being based on some math pattern, like the Mandelbrot set? [[User:Osias|Osias]] ([[User talk:Osias|talk]]) 02:38, 4 September 2014 (UTC)

It reminded me of the [http://articles.cnn.com/2012-04-13/tech/tech_web_apple-mac-virus-fix_1_mac-users-malware-mac-os?_s=PM:TECH Flashback Virus] that happened on Macs --[[User:Toddr|Toddr]] ([[User talk:Toddr|talk]]) 21:41, 9 August 2012‎ (UTC)

I love this paragraph:
"Proponents of the singularity typically state that an "intelligence explosion",where superintelligences design successive generations of increasingly powerful minds, might occur very quickly and might not stop until the agent's cognitive abilities greatly surpass that of any human."

"OK team, you can stop now, we are much more intelligent than they are"
"Don't we need to keep learning"
"Nah!"

I think there are two ways of interpreting it. The most likely is that Megan's "What did you do!?" is a cry of frustration and amazement that Cueball has managed to *so* break the server. First, how on earth did Cueball's $PATH get changed *at all* so that executing "ls" in the shell ran anything but the usual /bin/ls? Second, how did it end up pointing to that ls.jar? And third, what the heck did Cueball do to end up with that ls.jar being installed there anyway!? Then her "You should shut down..." comment should be interpreted as being preceded with the phrase "You are so clearly not qualified to use a computer that ...". On the other hand, she may be expressing awe and amazement at his ability to interact with his system in such a bizarre way. And then her "You should shut down ..." comment should be preceded with the phrase, "You are clearly so at one with computing machinery that ..." TK 2012-08-17

or you could edit $PATH and do a soft link from the first member of PATH/ls to /usr/share/Adobe/doc/example/android_vm/root/sbin/ls.jar, anyway if i was Megan i wouldn't give up just yet, i still have /bin/ls and dir in my disposal... (and always check the environment variables... never assume the user's environment is clean.. it's just most likely that $PATH got screwed up (happened a bit too often for my liking in my previous company.. some people just love to use the command "set PATH=/myprog" instead of set PATH=${PATH}:/myprog ) and all you had to do is to reset the variable and we are done :) (but ya.. Megan's reaction is also my reaction.. it's fun to see people helpless and think that they have royally screwed up their system when you swoop in like a super hero to miraculously repair their system) [[Special:Contributions/118.101.220.167|118.101.220.167]] 09:59, 4 December 2012 (UTC)

Considering Cueball's response, which suggests he is completely unaware of the unlikeliness of the error message, we can assume that the latter is not the case. Cueball totally fails to miss the point by suggesting a simple solution while not realizing how messed up his system would need to be to not even be able to operate the ls command. --[[Special:Contributions/88.75.181.101|88.75.181.101]] 02:45, 20 September 2012 (UTC)

Cueball has somehow messed up his path so that 'ls' now points to ls.jar, which executes the command on an external device (presumably an Android device). {{unsigned ip|134.134.139.72|18:15, 28 August 2012 (UTC)‎}}

Cueball's last line is a reference to an error message from the 8-bit era that went something like "Device not ready" or "device busy, try again later" which led some people to interpret it (literally) that they should try again later, when it really meant "the drive can't read the floppy disc that's in it".

I wrote an explanation for the body of the comics, but I believe there are aspects of the title I'm still missing, so I left the incomplete tag in place. [[User:Shachar|Shachar]] ([[User talk:Shachar|talk]]) 07:52, 18 September 2013 (UTC)

Isn't google already running applications designed to continue running even if some of nodes they run on have a fatal hardware failure? Also, even if the claim would be true in "practical" sense, it would not solve the problem, because as you said, the stopping would be because of reasons external to the actual program. In other words, program running on turing machine will never stop by hardware failure, because turing machine BY DEFINITION doesn't have any. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 08:57, 18 September 2013 (UTC)

"For all practical purposes, this is the correct solution"
:No, it's not. A very practical purpose would be "have my OS kill processes that won't stop". Other one would be "reject installing apps that contain algorithms that don't halt". If the OS assumes "every app will eventually halt" it would kill every process and reject every app. [[User:Osias|Osias]] ([[User talk:Osias|talk]]) 12:15, 18 September 2013 (UTC)
