Yes, one thing to note is how to get the hell out of the cave near the volcano [[Special:Contributions/108.162.249.159|108.162.249.159]] 22:38, 24 November 2015 (UTC)

The image is made up of small images with addresses of the form http://xkcd.com/1608/XXXX:-YYYY+s.png (although not every coordinate inside the bounds has an image associated). A script could probably dump out all the images and paste them together. --[[Special:Contributions/108.162.216.6|108.162.216.6]] 22:46, 24 November 2015 (UTC)

West -- Under Lava Pools -- Elon Musk's Secret Volcano Base (not as enjoyable as you might expect).

The Starship out east contains, among other things, Darth Vader, apparently explaining Steven Universe to a subordinate. (Steven and the Crystal Gems can be found a the west end of the ship, near an ice cream cooler.) The same ship contains an elaborate homage to the original Prince of Persia. {{unsigned ip|162.158.56.5}}

It's actually 169 coins (t.length). --[[Special:Contributions/188.114.111.129|188.114.111.129]] 23:22, 24 November 2015 (UTC)

I got 153 coins!! :D There's two starships, one's a star destroyer with an expansive maze dropping regular torpedoes on the other. May be noteworthy that there are various references to Star Wars and Steven Universe throughout. [[Special:Contributions/108.162.221.13|108.162.221.13]] 23:27, 24 November 2015 (UTC)

The second starship is the TantiveIV, Leia's ship at the beginning of episode 4. Note directly below the Tantive, the terrain seems to be sand dunes. Also there are two more space ships by the volcano; an X-wing at a gas station and an Apollo Command Module. {{unsigned ip|108.162.216.24}}

Tiles are located here in a zip: https://up1.ca/#Gi51KPFyPRELe0T1D6q9Mw All I did was iterate over http://xkcd.com/1608/X:-Y+s.png from X=[916...1116] and Y=[916...1116].

Alright, the full png of the entire map is almost finished, I should have used white tiles as blank tiles but I guess I can fix that up in gimp, and I'm not sure how to account for the 1 pixel overlap with just imagemagick convert.

I got 159 coins without the map. If you guys are still wondering how to escape the volcano, move to the right for as long as you think you can, then start spamming the up key while switching between holding the left and right keys. It worked for me on my first try.[[Special:Contributions/162.158.252.119|162.158.252.119]] 07:06, 25 November 2015 (UTC)

Didn't take down the coordinates, but the layout to the first level of the original Prince of Persia is in there, including the guard standing by with his scimitar!

Just thought this was interesting, when you "complete" the game by dropping coins, the following line of javascript is run, which sends your result to the server (L is number of coins, z is seconds used):
(new Image).src = "//xkcd.com/events.gif?coins=" + L + "&seconds=" + z;
Don't be tricked by the .gif extension, it doesn't show an image when opened, and the server probably handles this request by logging it to somewhere. {{unsigned ip|141.101.80.87}}

Is there a way that we can merge the "game" part of this comic with the map of [[1110: Click and Drag]]? Allowing us to explore that one in a similar way? [[User:Bon|Bon]] ([[User talk:Bon|talk]]) 11:03, 25 November 2015 (UTC)

Well I managed to find (nearly) everything, except the floating rock island, and 162 coins without the map, but even with looking at several maps, I didn't pass any graveyard nor found the way to the grey ocean, which I assume is underneath the "continent". Does anyone know where the entrance is? [[Special:Contributions/162.158.90.218|162.158.90.218]] 11:54, 25 November 2015 (UTC)

Just thought I should say; the comic supports some alternative movement controls, there's the arrow keys, WASD, and also the vi keys (hjkl), and the numpad (8426). [[Special:Contributions/108.162.242.125|108.162.242.125]] 13:29, 25 November 2015 (UTC)

I was not able to get to some points because they were surrounded by text, people or other objects. Is that normal, or are there tricks to get to every coin without using cheats (console)? It would be nice if this could be mention / explained in the article. [[Special:Contributions/162.158.135.35|162.158.135.35]] 13:31, 25 November 2015 (UTC)
:In some cases you can come in from the side as opposed to trying to come down through or up through something. Example: at the X-Wing "gas station", to get that coin, land on the ground to the left of the X-Wing and move to the right on the ground towards the gas station.

The list of "areas" in the map would be much easier to read, and much easier to correlate with the map, if the origin were set to the starting area (that is, if the coordinates of the starting area were set to x:0, y:0). What is the reason for the very large numbers? --[[User:BlueMoonlet|BlueMoonlet]] ([[User talk:BlueMoonlet|talk]]) 15:50, 25 November 2015 (UTC)
: The large numbers are the actual ones used by the game code and displayed by the hacked-up "radar" so it was a natural choice to use them as they are. We could define some origin and count coordinates from it but we would have to agree on its position and then change the "radar" code and recalculate all coordinates written down already. -- [[Special:Contributions/162.158.90.224|162.158.90.224]] 08:53, 27 November 2015 (UTC)

The starting area is in no way related to pac-man. The lines are not all right angles, there is a timer, there's gravity, there are no aggressors, you're collecting coins instead of pellets.... Not every line maze is pac-man. This is an erroneous reference that should be removed. --[[Special:Contributions/198.41.235.167|198.41.235.167]] 17:16, 25 November 2015 (UTC)

I would personally work on de-obfuscating the full source code using the fragment found there but technically the source is covered by implicit copyright laws and that means that if I published a derived work I would be breaking those laws.

Can't be bothered working out how to edit the page, but the explanation contains the phrase "People holding anchor lines to a Star Destroyer" - they're holding anchor lines to a CR90 Corvette, specifically the Tantive IV, commonly referred to as the "Rebel Blockade Runner", which in turn is being *attacked by* a Star Destroyer.

Haven't read all the comments above so maybe someone has written about it?
If you click up it seems to count how many times. So it will just show white and then when you release again, it will take longer to hit the ground the longer you have pushed up. Tried with 100 clicks (9-10 seconds) and 200 clicks (20 seconds).
I got about 163 coins in about 15886 seconds. (4 hours and 24 minutes.) That was with breaks. It was written so shortly on the screen I did not manage to take it down for certain. But after that I read here about the 169 and found that there where at least three in the volcano I had not noticed at first. And it seems likely that there would be three more I have missed. But really fun to explore. I wrote a lot of the transcript along the way (not from the very start though) This I have now posted without any real order in the [[1608: Hoverboard/Transcript]] page. Hope fully a full and useful transcript can emerge from this. I hope my text can be used if not used as it is written at the moment.--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 02:05, 26 November 2015 (UTC)

Just added in the 'collision detection' section the text "On a slow connection, it's possible to move into an 'open' area and then the black image loads in and (probably permanently, without tricks) traps you immobile." To expand upon this, if this is a risk to anyone else (I'm reliant on mobile internet, being away from any comparable landline capability) then you need to look out for perfectly horizontal/vertical edges. For example, hovering up the side of the Washington monument and encountering (typically above the 'bricks' line) a completely flat top. Drifting onto that soon gets you embedded in the remaining Monument, somewhere well below the eventual tip. Alternately, drifting sideways over the landscape and discovering a perfectly vertical cliff downwards (just past the bowling pins is a prime location) tempts you to drift down it and then suddenly the solid land 'happens' around you, forcing a page-refresh and restart (though doubtless there's also various console tricks that could be used). The well, also 'opens out', but it's a lie. I've ended up trapped 'in white' below the now closed black blocks that surround the well bottom (and not found any way back up). But if there a 'texture' (like other cliffs) or 'slope' (like the real Monument edge) to the surface, you're probably Ok. It's a genuine surface or wall that you can generally navigate around without fear of being misled. (Or so is my experience.)

----

We definitely need a better presentation of interesting objects/locations and their coordinates. Now, we have quite comprehensive multi-level bullet list and a newly-started table. Neither is perfect. We need some form that will show clearly what is where and where it belongs.

Issues to solve:
* Many objects are large and a single coordinates pair simply don't describe them well. We need a clear presentation form that will allow putting both a single pair and several ones, e.g. top and bottom for thin vertical objects (e.g. poles, The Monument), four corners for objects occupying large swaths etc.
* Grouping - we need to group objects that belong to an area, like all things within the Star Destroyer etc. Multilevel bullets are ok, but how to do that in a table?
* Order - within groups and between them, we need some ordering that will organize the entries. For example left-to-right then top-to-bottom or something like that.
* Coordinates system - the "native" game coordinates are large numbers, and negative values for the y coordinate to boot. Someone proposed setting a new origin and counting from there. I think it's a good idea, but will require a firm decision, rewrite of radar code and recalculating of all coordinates written down so far.

Any ideas?

:If it weren't for so much effort put in already, I think that we ''could'' re-class features as follows:
:* All coin locations, and/or links to the locations they are associated with (e.g. "in original game area" and "carried by a quadcopter drone"), if that's not considered 'unfair' to those wanting to actually play the game (without the self-discipline not to browse the list ;).
:* Locations of all characters, certainly all stick-figures, but maybe also 'wildlife' (or automata) of notable types.
:* All monologues/dialogues/labels (albeit that this is almost entirely a subset of the prior list).
:* Other notable landscape (or structural) features that are more than mere 'flavour' (e.g. the T-shaped mushrooms/whatevers to the east, but not random ground-boulders).
:* Notable move-through spots; inclusive of 'sink-into'able waters/magmas (waist-height, neck-height, fully-submerged?), even when not featuring further hidden routes, but excluding vegetation (ground-grasses/tree-trunks) that ''mostly'' are pass-throughable.
: Some of these are themselves useful references to other items (e.g. "inside front of Blockade Runner" or "beneath eastern stretch of magma") and so can probably be sub-grouped as all items in a given structure ("coins within the initial play area", "characters/speech within the Star Destroyer") and some things do occupy a swathe (the 'play area', the Monument, the ships, the kites, with their strings; the hail of (regular) torpedoes). And I bet there's a whole lot of arguments about what level of detail we could go to... [[Special:Contributions/162.158.152.227|162.158.152.227]] 10:21, 27 November 2015 (UTC)

Just thought this was interesting, when you "complete" the game by dropping coins, the following line of javascript is run, which sends your result to the server (L is number of coins, z is seconds used):
(new Image).src = "//xkcd.com/events.gif?coins=" + L + "&seconds=" + z;

Haven't read all the comments above so maybe someone has written about it?
If you click up it seems to count how many times. So it will just show white and then when you release again, it will take longer to hit the ground the longer you have pushed up. Tried with 100 clicks (9-10 seconds) and 200 clicks (20 seconds).
I got about 163 coins in about 15886 seconds. (4 hours and 24 minutes.) That was with breaks. It was written so shortly on the screen I did not manage to take it down for certain. But after that I read here about the 169 and found that there where at least three in the volcano I had not noticed at first. And it seems likely that there would be three more I have missed. But really fun to explore. I wrote a lot of the transcript along the way (not from the very start though) This I have now posted without any real order in the [[1608: Hoverboard/Transcript]] page.

Just added in the 'collision detection' section the text "On a slow connection, it's possible to move into an 'open' area and then the black image loads in and (probably permanently, without tricks) traps you immobile." To expand upon this, if this is a risk to anyone else (I'm reliant on mobile internet, being away from any comparable landline capability) then you need to look out for perfectly horizontal/vertical edges. For example, hovering up the side of the Washington monument and encountering (typically above the 'bricks' line) a completely flat top. Drifting onto that soon gets you embedded in the remaining Monument, somewhere well below the eventual tip. Alternately, drifting sideways over the landscape and discovering a perfectly vertical cliff downwards (just past the bowling pins is a prime location) tempts you to drift down it and then suddenly the solid land 'happens' around you, forcing a page-refresh and restart (though doubtless there's also various console tricks that could be used). The well, also 'opens out', but it's a lie. I've ended up trapped 'in white' below the now closed black blocks that surround the well bottom (and not found any way back up). But if there a 'texture' (like other cliffs) or 'slope' (like the real Monument edge) to the surface, you're probably Ok. It's a genuine surface or wall that you can generally navigate around without fear of being misled. (Or so is my experience.)

----

We definitely need a better presentation of interesting objects/locations and their coordinates. Now, we have quite comprehensive multi-level bullet list and a newly-started table. Neither is perfect. We need some form that will show clearly what is where and where it belongs.

Issues to solve:
* Many objects are large and a single coordinates pair simply don't describe them well. We need a clear presentation form that will allow putting both a single pair and several ones, e.g. top and bottom for thin vertical objects (e.g. poles, The Monument), four corners for objects occupying large swaths etc.
* Grouping - we need to group objects that belong to an area, like all things within the Star Destroyer etc. Multilevel bullets are ok, but how to do that in a table?
* Order - within groups and between them, we need some ordering that will organize the entries. For example left-to-right then top-to-bottom or something like that.
* Coordinates system - the "native" game coordinates are large numbers, and negative values for the y coordinate to boot. Someone proposed setting a new origin and counting from there. I think it's a good idea, but will require a firm decision, rewrite of radar code and recalculating of all coordinates written down so far.

Any ideas?

:If it weren't for so much effort put in already, I think that we ''could'' re-class features as follows:
:* All coin locations, and/or links to the locations they are associated with (e.g. "in original game area" and "carried by a quadcopter drone"), if that's not considered 'unfair' to those wanting to actually play the game (without the self-discipline not to browse the list ;).
:* Locations of all characters, certainly all stick-figures, but maybe also 'wildlife' (or automata) of notable types.
:* All monologues/dialogues/labels (albeit that this is almost entirely a subset of the prior list).
:* Other notable landscape (or structural) features that are more than mere 'flavour' (e.g. the T-shaped mushrooms/whatevers to the east, but not random ground-boulders).
:* Notable move-through spots; inclusive of 'sink-into'able waters/magmas (waist-height, neck-height, fully-submerged?), even when not featuring further hidden routes, but excluding vegetation (ground-grasses/tree-trunks) that ''mostly'' are pass-throughable.
: Some of these are themselves useful references to other items (e.g. "inside front of Blockade Runner" or "beneath eastern stretch of magma") and so can probably be sub-grouped as all items in a given structure ("coins within the initial play area", "characters/speech within the Star Destroyer") and some things do occupy a swathe (the 'play area', the Monument, the ships, the kites, with their strings; the hail of (regular) torpedoes).

625: Collections

2015-12-04T12:23:43Z

162.158.90.187: /* Explanation */

{{comic
| number = 625
| date = August 19, 2009
| title = Collections
| image = collections.png
| titletext = You know what really helps an existential crisis? Wondering how much shelf space to leave for a Terry Pratchett collection.
}}

==Explanation==
[[Cueball]] enters, excited that he's managed to buy every one of author {{w|Terry Pratchett}}'s {{w|Discworld}} books for his {{w|Amazon Kindle|Kindle e-reader}}. [[Megan]] says that it seems pointless to her to build a Kindle collection.

Cueball interprets this to mean she thinks it's pointless to build a collection on an electronic device, perhaps due to the DRM ({{w|digital rights management}}) software common on these devices which can (for instance) make it difficult to transfer the files if the device breaks. (This was the subject of [[488: Steal This Comic]] and DRM has been the general subject of [http://www.explainxkcd.com/wiki/index.php?search=DRM&go=Go&title=Special%3ASearch many xkcd comics].)

However, Megan is ''actually'' commenting on the futility of building up any kind of collection at all, since nothing we do can change the fact that we're inevitably going to die. And when we die, we always die alone - i.e. no one else can follow you on that last journey. And no matter how much you have collected (or earned) during this life that will not change. (A {{w|magpie}} is a bird traditionally thought to be drawn to collect shiny objects and bring them back to its nest.)

This view is in line with those advanced by the philosophical movement known as {{w|existentialism}} which theorizes that life has no deep, hidden meaning and hence even things that we personally feel are meaningful (like building up collections) will not change the outcome of life in the end.

Cueball obviously has seen Megan is such moods before (see [[220: Philosophy]]), and excuses himself for not noticing immediately (in the first panel) by the fact that he sometimes mistakes her {{w|existential crisis}} as technical insight. Megan deepens her crisis by pointing out that she sometimes makes the mistake to think that the {{w|universe}} cares. This is a disguised criticism of Cueballs behaviour, meaning that she would rather want him to care about her existential crisises, instead of simply brushing them of.

In the title text Cueballs tries to tell her what would help her out of her existential crisis. And this should be achieved by ''Wondering how much shelf space to leave for a Terry Pratchett collection.'' (That would then be all his works not just the Discworld series...)

By the time of his death Pratchett had written 41 Discworld books and more than 70 books in total. The day after Pratchett died [[Randall]] made a tribute comic to his memory in [[1498: Terry Pratchett]].

==Transcript==
:Cueball: I now have every Discworld book!
:Megan: Eh. Building a Kindle collection seems pointless.

:Cueball: Yeah, I know the DRM means I'll probably lose them someday.
:Megan: No, pointless in general.

:Megan: Sure, you satisfy deep magpie-like urges by building neat collections, but you still die alone.

:Cueball: Sorry, sometimes I mistake your existential crises for technical insights.
:Megan: Sometimes I mistake this for a universe that cares.

162.158.90.187:

Does anyone else think that the red spiders are supposed to be revealed as unexpectedly huge in this entry of the Red Spiders series, and that's to what the "Uh-oh" in the title text refers? That is, the humans in "[[Counter-Red_Spiders|Counter-Red Spiders]]" thought they could fight the red spiders, but the perspective in "Red Spiders Cometh" reveals the red spiders to be building-sized rather than person-sized? ...Or am I probably just over-thinking this, and the spiders' blocks are curving down from the viewer toward the city, resulting in a false apparent size, and the "Uh-oh" just refers to their arrival? Because it really seems to me that 1: the spiders are on a much larger scale than humans, and 2: this is a troubling revelation as of "Red Spiders Cometh".

Guys? Anyone feel that the grammar error (unless I'm to be a silhouette on someone's desk soon) is worth mention? "Cometh" is third person ''singular'' ("he cometh", but "they come") after all... Unless I'm wrong.

:I think it is probably a pun on "comets", which the spiders are kind of falling down along with. 02:18, 8 November 2015 (UTC)

5: Blown apart

2015-11-01T09:22:20Z

162.158.90.187: Mention about the case where all three prime factors of 70 are multiplied together to get 70 itself.

{{comic
| number = 5
| date = October 25, 2005
| title = Blown apart
| image = blownapart_color.jpg
| titletext = Blown into prime factors
}}

==Explanation==
The title text explains the comic. An {{w|anthropomorphism|anthropomorphic}} number 70 is blown into its {{w|prime factor}}s (2, 5 and 7). {{w|Prime number}}s are numbers which can not be divided by any number other than itself and 1. Factors of a number are numbers which can be multiplied together to produce that number (2x5x7 = 70). 70 has other factors, including 1, 10, 14, 35 and 70, but 2, 5 and 7 are the only factors which are prime. All other factors of 70 (other than 1) can be formed by multiplying two (or three for 70 itself) of the prime factors together.

==Transcript==
:[A black number 70 sees a red package.]
:70: hey, a package!

:[The package explodes with a '''BOOM''' and an brown cloud of smoke.]

:[There are a red 7, a green 5 and a blue 2 lying near a scorched mark on the floor.]
