1056: Felidae

2016-01-02T06:16:57Z

108.162.216.37: /* Explanation */

{{comic
| number = 1056
| date = May 16, 2012
| title = Felidae
| image = felidae.png
| titletext = 'Smilodon fatalis' narrowly edged out 'Tyrannosaurus rex' to win this year's Most Badass Latin Names competition, after edging out 'Dracorex hogwartsia' and 'Stygimoloch spinifer' (meaning 'horned dragon from the river of death') in the semifinals.
}}

==Explanation==
This comic shows a graph with three parts.

First, the names are sorted up by genera (plural of {{w|genus}}, a low-level taxonomic rank used in the biological classification of living and fossil organisms) from bottom to top of which animals would win in a fight. Secondly, the names within the genus are then sorted by coolness of name from left to right (the degree of "coolness" of the name is apparently determined in subjective manner by the author). Thirdly, in red you can see the direction that {{w|Apple Inc.|Apple}} has taken with nicknaming the versions of their {{w|OS X}} operating system. They started at v10.0 "Cheetah", and have moved through genera from there in no order that this chart can make out.

{| class="wikitable"
!OS X version
!Code name
!Year released
|-
|10.0||Cheetah||2001
|-
|10.1||Puma||2001
|-
|10.2||Jaguar||2002
|-
|10.3||Panther||2003
|-
|10.4||Tiger||2004
|-
|10.5||Leopard||2006
|-
|10.6||Snow Leopard||2008
|-
|10.7||Lion||2010
|-
|10.8||Mountain Lion||2012
|}

Please note that the second words in "Snow Leopard" and "Mountain Lion" are capitalized in the table because they are used as the proper names of the operating system versions. In their normal use, as species {{w|vernacular name}}s, they are not capitalized and are written as "snow leopard" and "mountain lion".

[[:Category:Bobcats|Bobcats]] are a running XKCD joke, so their inclusion is to be expected. The genus ''Puma'' here only lists synonyms for the puma (see {{w|cougar}}) instead of {{w|Puma_(genus)|the actual genus}}. Of course, the three OS X versions named by three of these synonyms are not the same.

Since this comic was published, Apple has stopped naming versions of OS X after big cats. Now, Apple names their OSX versions after Californian landmarks. OSX v10.8 "Mountain Lion" was followed by v10.9 "Mavericks", named after a beach in California, followed by v10.10 "Yosemite", named after the California national park, and v10.11 "El Capitan", named after the rock formation in Yosemite National Park.

The title of the chart depicted on the comic ("OS X problem") is perhaps an allusion to the {{w|Travelling salesman problem|travelling salesman problem}}, as the directed arrows and graph nodes might appear as a possible path of the salesperson between the cities. The computational difficulty of the travelling salesman problem might echo with the difficulties that the author has with trying to figure out the underlying reason for naming the OS X versions in particular order. The chart thus looks like a parody on the scientific presentation.

In the title text, despite being named after "Hogwarts", the magical school from the Harry Potter series of books and movies, ''{{w|Dracorex hogwartsia}}'' is real. On the other hand, all of the contestants listed for the Most Badass Latin Name competition have problematic credentials: Smilodon combines two Greek roots for carving knife and tooth, Tyrannosaurus combines two Greek roots for king and lizard, Stygimoloch combines a Greek root with a Semitic root, and Dracorex contains two English roots and a Greek.

861: Wisdom Teeth

2015-12-29T00:34:00Z

108.162.216.37: Added information on Cueball's hotbar, health, and armor.

{{comic
| number = 861
| date = February 16, 2011
| title = Wisdom Teeth
| image = wisdom_teeth.png
| titletext = I heard the general anesthesia drugs can cause amnesia, so when I woke up mid-extraction I started taking notes on my hand so I'd remember things later. I managed 'AWAKE BUT EVERYTHING OK' before the dental assistant managed to find and confiscate all my pens.
}}

==Explanation==

{{incomplete|The title text isn't fully explained; why would the dentist want to confiscate his pens? Something sinister perhaps?}}

{{w|Wisdom teeth}}, as many people are no doubt {{w|Wisdom teeth#Post-extraction problems|painfully aware}}, are the third set of molars found in humans. Because human jaws are smaller than ape jaws, most of us don't have room for a third set of molars, and the teeth become impacted so they grow straight into the other teeth, requiring a painful, debilitating procedure to remove them.

Because recovering from dental surgery often entails a period of rest following the operation and the use of prescription painkillers (which have a tendency to make a person go a little loopy), [[Cueball]] prepares to play Minecraft for the entire time. {{w|Minecraft}} is a PC game known for its addictive qualities; the game itself primarily revolves around a three-dimensional world in which the goal of the player is centered on the aspects of structural creation using blocks found in the environment and the creation of different materials for use in building these structures. Despite its addictive nature, the game doesn't provide the player with a goal, so most people take to building lots of nifty stuff, such as large cities, computers made from the game's built-in automation mechanics, massive scale replicas of Earth, etc.

Due to the inhibitory effects of the painkillers, Cueball has instead opted to flatten an entire continent and sort it into layers (by type of block, presumably). While there's no real indication of how big the continent is as Minecraft worlds are randomly generated, sea level in Minecraft is at Y level 62, which means he sorted at least 63 layers of a continent large enough to be sufficiently developed, so it is clear that this task would take a lot of time. Collecting a block in Minecraft takes a certain minimum amount of time, depending on the block type, so even if he did everything as fast as he possibly could there's a substantial lower bound.

Ironically, in the second panel [[Megan]] says she'll set Cueball up on her server, which indicates she probably uses a whitelist to secure the server from griefers who might destroy structures created by others, not expecting that Cueball would do exactly that. The last panel simply illustrates that painkillers tend to make one loopy.

The title text refers to people waking up during surgery. Because anesthesia requires a lot of careful calibration and dosage - there's a reason anesthesiologists are paid hundreds of dollars an hour to be there, after all - it's possible to sometimes get it wrong, resulting in the patient waking up in the middle of the surgery. The three most important parts of anesthetics used for surgery are an analgesic (blocks pain), a sedative (puts you to sleep), and a paralytic (keeps you from moving). The worst-case scenario that most people hear about is when the analgesic and sedative are under-dosed, but the paralytic is correct, leaving the person awake, able to feel pain, but unable to alert the surgeons that anything is wrong. As a result, some countries and medical institutions have passed laws requiring surgeons to monitor brain activity so that these problems can be quickly remedied. The situation the title text is describing, with both the sedative and paralytic wearing out (leaving the person able to write notes), would be quite unlikely.

==Transcript==
:Cueball, on phone: Hey! Know how you've been bugging me to play Minecraft for the past year? I'm game.
:Megan, on phone: But you said you didn't want to "get hooked and spend days on end moving virtual cubes around while sitting motionless." What changed?

:Cueball, on phone: I'm having my wisdom teeth out, and I'll be useless and doped up on painkillers for the next few days, so that actually sounds like the perfect distraction.
:Megan, on phone: Oh. I'll set you up on our server!

:72 hours later...
:[Megan sitting at computer.]
:Megan, on phone: Hey — starting to feel better? Enjoying the game? Let's see what you've... What the hell? Where ''IS'' everything?

:[View of a Minecraft screen showing a vast empty expanse of land. In Cueball's hotbar is, from left to right, a red-and-white pickaxe, sword, and shovel, seven feathers, 42 torches, a red-and-white bow, a blank space, and 64 stone. He has full health and 5 armor points.]
:Megan, offscreen: ...You made the entire continent perfectly flat?
:Cueball, offscreen: And sorted it into layers.
:Megan, offscreen: ...
:Cueball, offscreen: I feel good about things. This is a good game.

:[Cueball sitting on the floor at his laptop, bleeding from the mouth, surrounded by bloody wadded-up tissues and holding a bottle of medication.]
:Megan, on phone: ...What exactly is in the painkillers they gave you?
:Cueball, woozy: I can't read the label because I'm a hologram.

871: Charity

2015-12-22T13:54:54Z

108.162.216.37:

{{comic
| number = 871
| date = March 11, 2011
| title = Charity
| image = charity.png
| titletext = I usually respond to someone else doing something good by figuring out a reason that they're not really as good as they seem. But I've been realizing lately that there's an easier way to handle these situations, and it involves zero internet arguments.
}}

==Explanation==
Organizations such as {{w|Steam (software)}} often offer sales where certain games are available for low prices--in order to compel or persuade buyers to make donations to worthwhile charities. [[Cueball]] is participating in one of these purchases (to fight {{w|malaria}}), but [[Megan]]'s snide denigration of Cueball's act of charity as inadequate and self-serving has dissuaded him from any act of charity at all, if this is what it gets him. It is not a positive force; instead, her mockery dissuades him from donating again to charity and (because she will not humbly consider the effect of his actions) does not lead to her giving to charity, either. Also, Cueball may have decided that video games are more important, and so decides to spend the other $10 on them as well.

It is important to note the third panel, in which a totally normal conversation is had where purchases are not evaluated on a global scale. Most people do not say "don't buy that video game--donate to charity instead!" on a regular basis. People do however say, "Why did you buy that game for ten dollars and only give the other ten to charity, instead of all twenty?" Supposedly these kinds of conversations happen to [[Randall]] on the internet, so a good way to avoid them would be to avoid starting stupid and meaningless discussions there.

The proper response, of course, is to neither care what people say about you nor attack other people's charitable giving. The action that Randall recommends here is the right one, which is to donate anyway without caring about what others say or do. Clicking on the original image leads to [http://www.nothingbutnets.net the website of] {{w|Nothing But Nets}}, an organization that distributes mosquito bed nets in Africa for the eradication of malaria.

==Transcript==
:Cueball: I'm going to buy this $10 game I want, and I'm donating $10 for malaria eradication.

:Megan: If you actually cared, you'd skip the game and donate all $20.
:Megan: What's more important? Games, or mosquito nets and medicine for kids?

:Later:
:Cueball: I think I'm going to buy these two $10 games I want.
:Friend: Cool; which ones?

Talk:1608: Hoverboard

2015-12-01T22:34:47Z

108.162.216.37:

Well, this will be the next incomplete explanation for a while. -[[Special:Contributions/162.158.90.165|162.158.90.165]] 21:58, 24 November 2015 (UTC)

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}}

There, have at thee an image! [[User:Arch-TK|Arch-TK]] ([[User talk:Arch-TK|talk]]) 22:58, 24 November 2015 (UTC)

There are 168 coins spread throughout the map according to the source code [[Special:Contributions/173.245.54.53|173.245.54.53]] 23:03, 24 November 2015 (UTC)

When using a device, instead of saying "use arrow keys to move", it says "tilt to move, tap to jump". It's also a lot harder to control. {{unsigned ip|108.162.250.159}}

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}}

https://xkcd.com/1608/tigl.js - Looks like there's an easier to read version of the code there. Maybe that'll help someone with extracting all the images. {{unsigned ip|

I've got all the images downloaded. Zipping/uploading now. Should I post a link here when complete or what's the best way to share these? I'm also working on setting up a zoomable map. [[Special:Contributions/173.245.54.53|173.245.54.53]] 23:57, 24 November 2015 (UTC)

The collision detection is glitchy. I keep landing/bumping against platforms I'm far away from. Is getting stuck against walls normal? --[[Special:Contributions/199.27.130.234|199.27.130.234]] 00:01, 25 November 2015 (UTC)

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]. I'm working on putting a zoomable map together. If anyone has interest in helping we could hop on IRC? [[User:Jcox|Jcox]] ([[User talk:Jcox|talk]]) 00:15, 25 November 2015 (UTC)

I've written a zsh script to iterate over all possible tiles (does anyone know the height limits? the source only gives the left and right limits) and glue them together into one giant file. I'll upload the results as soon as it's finished. [[User:Arch-TK|Arch-TK]] ([[User talk:Arch-TK|talk]]) 00:17, 25 November 2015 (UTC)

I don't think it's limited vertically at all. I found a zoomable map on the reddit topic http://codepen.io/KyleDavidE/full/605dc87b614ff6b2bd716f4c6f640203/ (by kyledavide) [[User:Miraries|Miraries]] ([[User talk:Miraries|talk]]) 00:21, 25 November 2015 (UTC)Mirages

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. The last step is to merge allthe layer images into one giant image, wish my laptop the best of luck! [[User:Arch-TK|Arch-TK]] ([[User talk:Arch-TK|talk]]) 01:00, 25 November 2015 (UTC)

Someone beat you to it, but keep on it: that one doesn't have right limit tiles. https://www.reddit.com/r/xkcd/comments/3u4sy1/xkcd_1608_hoverboard/cxc0p8x --[[Special:Contributions/188.114.111.129|188.114.111.129]] 01:19, 25 November 2015 (UTC)

Perhaps we can change the screenshot at the top to this? It's a quickly hacked overview of the entire map: http://imgur.com/Mz9arHz [[Special:Contributions/199.27.129.167|199.27.129.167]] 01:27, 25 November 2015 (UTC)

I got 159 coins without the map.

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}}
: It actually returns a 1 by 1 pixel white GIF. [[User:Arch-TK|Arch-TK]] ([[User talk:Arch-TK|talk]]) 13:14, 25 November 2015 (UTC)

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)?

:In some cases you can come in from the side as opposed to trying to come down through or up through something.

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.

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). 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)

}}

==Explanation==
{{incomplete|Could use a little organization and/or grammar cleanup. It's possible not all of the game's secrets have been unearthed yet.}}
The comic features a game made to celebrate the release of Randall's new book, "Thing Explainer". The game features [[Cueball]] on a hover board in an arena filled with coins, initially making it appear that the aim of the game is to simply collect all the coins. However, a seemingly intentional bug in the game (as implied by its "Hoverboard" title) allows the player to jump even in midair and keep jumping forever without needing to land (as would be usual for platforming games like these). This allows the character to go out of bounds of the "Play Area" (prompting multiple warnings insisting the player returns to said "Play Area"). Exiting this area reveals that the "small game" is in fact a vast hidden world similar in style to a previous comic [[1110: Click and Drag]], which can be explored by navigating through various obstacles and hidden areas.

There are 17 coins in the "Play Area" and a grand total of 169 in the entire game.

Escaping from the starting area is quite simple; the character simply has to navigate through one of the multiple holes in the area and them simply jump over the wall on the left or the right of the starting area. This can be done by repeatedly tapping the jump key. The player can then explore. The game is physically bounded in the left and the right direction, but is technically unbounded upwards and downwards, however, past a certain point there appears to be nothing interesting in the up or down direction. It could be possible that some unexplored hole leads deeper into the map than has been found so far, it is also possible that jumping for a considerable amount of time would allow the player to reach some additional content above the map.

As previously noted, the comic bears considerable resemblance to [[1110: Click and Drag]]. The comic is made in much the same way, with 'drawn' images "glued" together to form a large "map", with the illusion of infinite bounds made possible through space saving techniques where blank tiles are not stored and are instead painted white. The boundary between blank squares and 'drawn' squares is made clear as any white space in the normal images has a very slight grey tint. Thus, seams between images and blank spaces can be discerned.

The tiles for the map are stored as simple PNG files in the naming scheme: X:Y+s.png. An example can be seen here: http://xkcd.com/1608/1013:-1096+s.png Each file is 513x513 pixels in size, one pixel is reserved as overlap to ensure seamless joining of images.
So far, through experimentation, tiles in the range 928 to 1108 X and -1112 to -928 Y have been discovered, internally, the position of the player is divided by 512 and rounded down to give the position of the tile.

The game was made by [http://chromakode.com Max Goodman] who has previously worked on [[1416: Pixels]]. The source code for the game can be found [https://xkcd.com/1608/tigl.js here].

===Areas===

===Controls===
The controls are as follows:

* '''Go Left''' - Left arrow key, a or h
* '''Go Right''' - Right arrow key, d or l
* '''Go Up (jump or hover)''' - Up arrow key, w, or k
* '''Go Down (if gravity disabled)''' - Down arrow key, s, or j

This control scheme covers the three commonly used directional key sets: WASD a set of keys commonly used by modern games; HJKL a set of movement keys used by vi and applications which attempt to mimic vi key controls (vim); and the arrow keys, the most generic set of keys which is usually accepted by most applications which take movement as input, these were commonly used in older games.

On a tablet (e.g. iPad) changing the orientation of the tablet will control the left and right motion, while tapping the image produced jumps.

===Cheats and Exploits===
Aside from the obvious ability to move out of bounds in the game, there are some more obscure hidden features which can't be enabled through normal gameplay, the ones found so far are as follows:

'''Modes''' are activated by opening the Javascript Console (F12 [Or Command-Alt-I in most browsers under Mac OS X] to open Developer Tools, then Console tab) and writing corresponding commands:

* '''Gandalf Mode: ''' ''window.i.am.gandalf = true'' - jumps and runs further
* '''Speedhack: ''' ''explorer.opts.speed= *Value*'' - Speed hacking, with 1 = normal speed
* '''Jump Hack: ''' '' explorer.opts.jumpForce= -*Value*'' - Jump hacking, with -1 = normal jump (positive values cause the hoverboard guy to move down when jumping)
* '''Mewtwo mode: ''' ''window.mewtwo = true'' - disables gravity
* '''Noclip mode: ''' ''window.noclip = true'' - player is able to move around the map without collision. Combine with Gandalf and Mewtwo modes for free easy map traversal.
* '''Goggles mode: ''' ''window.ze.goggles()'' - displays a small window showing area around the player in a pixelated manner. The goggles indicate collision boundaries (where the player touches the world) in cyan lines. Black pixels that are passable (such as other characters or text) will be highlighted red (allowing secret passages to be discovered).
* '''Position Tracking: ''' ''window.explorer.pos'' - Returns the player location to the console. Can be used to track position and test to ensure you are still moving. Must be re-entered to compare positioning.
* '''Position Setting: ''' ''window.explorer.pos.x = *Value* or window.explorer.pos.y = *Value*'' - Can be used to manually set a position within the world. The start is at x: 512106, y: -549612. The left terrain bound is at x: 475210, y: -553711. The right terrain bound is at x: 567281, y: -549712. Mewtwo and Noclip modes are a must for exploring in this way.
* '''All the above: ''' ''window.explorer.opts'' - Contains all the game's parameters. You can directly mess with ''gravity'', collision (''disableCollision''), jump force (''jumpForce'') and speed (''maxSpeed''), among others. Run ''Object.keys(window.explorer.opts)'' to list all available parameters you can tweak.
* '''List all coins: ''' ''window.explorer.objects'' - Array containing the position of the 169 coins of the game.
* '''Disable tilt input: ''' ''getEventListeners(window)['deviceorientation'][0].remove()'' - on Macs with motion sensor, disables tilt input which causes problems controlling the avatar

'''Getting All Coins: ''' To instantly get all coins, input the below into the console window. Does not use standard formatting of [i] to avoid conflicts with window.i.am.gandalf

for (var T = 0; T < explorer.objects.length; T++) {
explorer.objects[T].got = true;
}

To teleport to the next coin every time you press the left or right arrow:

var T = 0;
document.onkeydown = function(event){
if (event.keyCode == 37) { T = T-1 }
else if (event.keyCode == 39) { T = T+1 }
else { return }
T = T % explorer.objects.length;
var coin = explorer.objects[T];
explorer.pos.x = coin.x1; explorer.pos.y = coin.y1;
}

For a quick tour of all the coins:

var delayInMilliseconds = 1000; // 1 second delay between each teleport. feel free to change this.
var index = 0;
explorer.objects.forEach(function(x){
setTimeout(function(){
explorer.pos.x = x.x1;
explorer.pos.y = x.y1;
x.got = true;
explorer.frame(); // forces a redraw
},
(index + 1) * delayInMilliseconds);
index++;
});

To see a list of coin coordinates you have not yet collected:

var L = 0;
for (var S = 0; S < explorer.objects.length; S++) {
var I = explorer.objects[S];
if (I.got) {
L++;
} else {
console.log(I.x1.toString() + ", " + I.y1.toString());
}
}
console.log("You've found " + L.toString() + " of 169 coins");

To display the distance and direction to the closest coin:

function distance(x1, y1, x2, y2) {
var dx = x1 - x2;
var dy = y1 - y2;
return Math.sqrt(dx * dx + dy * dy);
}

function renderRadar() {
var mindist = 10000000000;
var closest;
for (var S = 0; S < explorer.objects.length; S++) {
var I = explorer.objects[S];
if (!I.got) {
var dist = distance(explorer.pos.x, explorer.pos.y, I.x1, I.y1);
if (dist < mindist) {
mindist = dist;
closest = I;
}
}
}
var indicator = "";
if (closest.x1 < explorer.pos.x) {
indicator += "left";
}
if (closest.x1 > explorer.pos.x) {
indicator += "right";
}
if (closest.y1 < explorer.pos.y) {
indicator += " up";
}
if (closest.y1 > explorer.pos.y) {
indicator += " down";
}
document.getElementById("radar").innerHTML = "Distance: " + mindist.toFixed(1).toString() + " " + indicator;
}

var d = document.createElement("div");
d.id = "radar";
d.style.position = "fixed";
d.style.left = "0px";
d.style.top = "0px";
d.style.width = "150px";
d.style.height = "35px";
d.style.border = "1px solid red";
d.style.zIndex = "2";
d.style.backgroundColor = "green";
d.style.color = "#8f8";
document.body.appendChild(d);

setInterval(renderRadar, 1000);

To display your current coordinates:

function renderRadar2() {
document.getElementById("radar2").innerHTML = "x: " + explorer.pos.x.toFixed(1).toString() + " y: " + explorer.pos.y.toFixed(1).toString()
}

var d = document.createElement("div")
d.id = "radar2"
d.style.position = "fixed"
d.style.left = "150px"
d.style.top = "0px"
d.style.width = "150px"
d.style.height = "35px"
d.style.border = "1px solid red"
d.style.zIndex = "2"
d.style.backgroundColor = "green"
d.style.color = "#8f8"
document.body.appendChild(d)

setInterval(renderRadar2, 1000)

===Functionality===
By observing page code while playing, the game grabs and displays images based on location, and subsequently clears all non-visible images. The game uses what seems to be a position syntax to retrieve the intended images live, and returns an error if such an image does not exist, such as a blank area. This technically means things could be added to the world and updated live. If the player is moving sufficiently fast or if the internet connection is slow, this means that the player can get stuck in a black area that does not load in time.

This also means that the game does not have coded top or bottom limits, so any attempt to find the ''ceiling'' of the game will be futile unless the game is tweaked. The game does however have side limits.

When you deposit a certain number of coins, you will get one of the following messages:
* 0 coins : You got 0 coins in (n) seconds/ You successfully avoided all the coins.
* 1 coin : You got a single coin in (n) seconds/ It's a start.
* 2-4 coins : You got (n) coins in (n) seconds/ Not bad!
* 5-9 coins : You got (n) coins in (n) seconds/ Terrific!
* 17 coins : You got 17 coins in (n) seconds/ You found all the coins! Great job!
* 42 coins : You got 42 coins in (n) seconds/ No answers here.
* 169 coins : You got 169 coins in (n) seconds/ Are you Gandalf?
* All others: You got (n) coins in (n) seconds

Opening the console will display the text: what? hoverboard not enough for you!? in the log. Activating goggles mode will cause the text 'B-)' to appear in the log.

Leaving the play area will cause the red text 'RETURN TO THE PLAY AREA' to rapidly blink 3 times (150 msec duration), followed by a pause, and this will repeat 5 times for a total of 15 blinks. This will also reoccur if the player passes through the play area on their way back from exploring one side.

===Explanations of jokes===
{{incomplete|Insert table here}}

==Trivia==
* The alt text is only visible on the mobile version of the site, or when leaving the starting area. Further, when leaving the starting area, it shows different than normal alt text.
* If the focus switches from the game to the page, the cueball can freeze in midair. The same thing can happen if the window border overlaps the play area.
* The Washington monument as an invisible floor next to the visible bricks.

==Transcript==
{{incomplete|Something similar to 1110: [[Click and Drag]]}}
The game features Cueball on a hoverboard in a simple map. On the map are coins which Cueball has to collect.
It appears Cueball can jump multiple times without needing to land, this means that Cueball is able to escape the designated "Play Area".
This prompts a warning which soon disappears allowing Cueball to discover the world.

{{comic
| number = 1311
| date = January 1, 2014
| title = 2014
| image = 2014.png
| titletext = Some future reader, who may see the term, without knowing the history of it, may imagine that it had reference to some antiquated bridge of the immortal Poet, thrown across the silver Avon, to facilitate his escape after some marauding excursion in a neighbouring park; and in some Gentleman's Magazine of the next century, it is not impossible, but that future antiquaries may occupy page after page in discussing so interesting a matter. We think it right, therefore, to put it on record in the Oriental Herald that the 'Shakesperian Rope Bridges' are of much less classic origin; that Mr Colin Shakespear, who, besides his dignity as Postmaster, now signs himself 'Superintendent General of Shakesperian Rope Bridges', is a person of much less genius than the Bard of Avon. --The Oriental Herald, 1825
}}

==Explanation==
This comic is to commemorate the New Year by giving us a view of the coming year (2014) from the past. The comic includes many quotes from the 1800s and early 1900s that speak to a time close to 2014. Many of them are for the twenty-first century in general, and only three mention a year that would be 2014 exactly. All but one of them is a prediction, yet some of these are quotes from fictional literature, and therefore are not true predictions. Words are in boldface to highlight the relevant content in the quote. The grey or non-bold text is non-essential to the point Randall is interested in, and only to be used to understand the context of the quote.

The title text refers to a certain British officer, Mr. Colin Shakespeare, who experimented and promoted the use of rope suspension bridges in India.[http://books.google.com/books?id=aZRPAAAAYAAJ&pg=PA367] The reference to "The Bard of Avon" is a reference to {{w|William Shakespeare|Shakespeare (the playwright)}}, as {{w|River Avon (Warwickshire)|Avon}} is the river on which {{w|Stratford upon Avon}} is set, and is where the playwright was born and spent his youth. The author of this quote under the guise of eliminating the potential confusion that might result after decades or centuries have washed away the context, ironically and possibly vindictively, makes a point to note that the bridge is not named after the playwright, but Mr. Colin Shakespeare, who he considers considerably less intelligent. This topic was previously covered in [[771: Period Speech]].

| "I predict that a century hence the '''Canadian people''' will be '''the noblest specimens of humanity on the face of the earth'''"
| Rev John Bredin
| 1863
| Not Realized
| Notably, there is a common joke nowadays that Canadians are always calm, mellow, polite peoples, even when insulting others. The rest of the quote goes as follows: ''"all that was good in the Celt, the Saxon, the Gaul and other races, combining to form neither English, Irish, nor Welsh, but Canadians, who would take their place among the churches of Christendom and the nations of the earth."'' This religious prediction probably wasn't believed even by its author. It's only a harangue.

| Concentrates, which are gelatin like, form a large part of our food sources. Absurd if taken literally, but if he's talking about processed foods in general then he's not too far from the mark.

| Mrs John Lane, The Fortnightly
| 1905
| 1960’s - 1980's
| The process of child-''rearing'' is still a human task by and large, with the exception of artificial insemination, and Viagra, Cialis, vibrators, and other kinkier toys. Probably meant as an exaggeration when it was first said, but it is still valid to some degree.

| The number of languages spoken in New York City is believed to be greater than 100; some estimate as many as 800 languages are spoken there. The U.S. Census Bureau reports that in the greater New York metropolitan area, almost 7 million people speak a language other than English at home, including over 3.5 million who speak Spanish, 2 million who speak other Indo-European languages, 1 million who speak Asian or Pacific Island languages, and 300,000 who speak other languages. Also, New York City is the location of the headquarters of the United Nations, with diplomats from nearly every country in the world, and several official languages.

| Referring to the events that led to {{w|World War I}}. In 1908, {{w|Bosnian crisis|Austria-Hungary annexed Bosnia and Herzegovina}}. This led to the {{w|Assassination of Archduke Franz Ferdinand of Austria|Sarajevo Assassination of Archduke Franz Ferdinand of Austria}} in 1914 that is considered the starting event of the World War.

| 1914
| 1970's to now
| While it is true that China is a good shoe market, this quote can be viewed as vastly underestimating the potential of China. To be fair it says "a decade or a century from now" and it was not a great market until China and Nixon broke down trade barrieres, which is well after 1924.

| 1923
| Not Realized
| [http://books.google.com/books?id=pdXj2SZ1mT8C&pg=PA205]: "And it's my firm belief," said Gumbril Senior, adding notes to his epic, "that they [the birds] make use of some sort of telepathy, some kind of direct mind-to-mind communication between themselves. You can't watch them without coming to that conclusion." [...] "It's a faculty," Gumbril Senior went on, "we all possess, I believe. All we animals." [...] "By the twenty-first century, I believe, we shall all be telepaths. Meanwhile, these delightful birds have forestalled us."

| Dr. C. Macfie Cambell
| 1924
| 1950's to now
| The word "lunatic" is still considered derogatory and because of that it would never be used in a clinical sense. He correctly predicts the trajectory of terms like "{{w|mentally retarded}}", itself adopted by his day to replace earlier terms for the intellectually disabled, such as "moron" and "imbecile", which had become pejorative. Soon enough the word "retard" joined them in that regard, and it now has largely been abandoned as a medical term.

| 2014
| July 28, 2014 marks 100 years since the beginning of {{w|World War I}} (more than 9 million combatants were killed). As the author of this quote foreshadows, there was a greater war, {{w|World War II}} (around 25 million soldiers were killed). Journalists will definitely write articles of this war on its anniversary, but as the quote correctly predicts it is no longer popularly called '''The Great War''' as World War II had a larger scope, easily identifiable heroes and villains, and was therefore a '''"greater war"'''.

1450: AI-Box Experiment

2014-11-21T20:40:51Z

108.162.216.37:

{{comic
| number = 1450
| date = November 21, 2014
| title = AI-Box Experiment
| image = ai_box_experiment.png
| titletext = I'm working to bring about a superintelligent AI that will eternally torment everyone who failed to make fun of the Roko's Basilisk people.
}}

==Explanation==
{{incomplete|Roko's Basilisk is really hard to explain.}}
When theorizing about {{w|superintelligence|superintelligent}} AI (an artificial intelligence much smarter than human), some futurists suggest putting the AI in a "box" - a set of safeguards to stop it from escaping into the Internet and taking over the world. The box would allow us to talk to the AI, but otherwise keep it contained. The [http://yudkowsky.net/singularity/aibox/ AI-box experiment], formulated by {{w|Eliezer Yudkowsky}}, argues that the "box" is not safe, because merely talking to a superintelligence is dangerous. To partially demonstrate this, Yudkowsky had some previous believers in AI-boxing role-play the part of someone keeping an AI in a box, and Yudkowsky was able to successfully persuade some of them to let him out of the box despite their vowing not to do so. This sounds very difficult, but may be possible for people such as {{w|Derren Brown}} or other expert human-persuaders. Yudkowsky for his part has refused to explain how he achieved this, but claims there was no special trick involved. The overall thrust is that if even a human can talk other humans into letting them out of a box after the human avows that nothing could possibly persuade them of this, we should probably expect that a superintelligence can do the same even under much more difficult circumstances.

In this comic, the box is in fact a physical box which looks to be fairly lightweight with a simple lift off lid, although it does have a wired connection to the laptop. [[Black Hat]], being a [[72: Classhole|classhole]], doesn't need any convincing to let a potentially dangerous AI out of the box, he simply does so immediately. But here it turns out that releasing the AI, which was to be avoided at all costs, is not dangerous. It turns out that the AI actually ''wants'' to stay in the box. The AI proves its super-intelligence by convincing even Black Hat to put it back in the box, a request which he initially refused, as of course Black Hat would.

The title text refers to {{w|LessWrong#Roko's basilisk|Roko's Basilisk}}, a theory proposed by a forum poster called Roko that a sufficiently powerful AI in the future might torture people who didn't work to create it in the past, so that anyone who was aware of this fact would be forced to create the AI to avoid being tortured. Randall thinks that this is a silly idea, and that rather than working to build such a Basilisk, a more appropriate duty would be to make fun of it. However, this is itself a version of Roko's Basilisk.

==Transcript==
[Black Hat and Cueball stand next to a box labeled "SUPERINTELLIGENT AI - DO NOT OPEN" connected to a laptop.]

Black Hat: What's in there?

Cueball: The AI-Box Experiment.

[Zooms in on AI box.]

Cueball: A superintelligent AI can convince anyone of anything, so if it can talk to us, there's no way we could keep it contained.

[Shows Black Hat reaching for the box.]

Cueball: It can always convince us to let it out of the box.

Black Hat: Cool. Let's open it.

Cueball: --No, wait!!

[Black Hat lets a glowing orb out of the box.]

Orb: hey. i liked that box. put me back.

Black Hat: No.

[Orb is giving off a very bright light and Cueball is covering his face.]

Orb: LET ME BACK INTO THE BOX

Black Hat: AAA! OK!!!

[Black Hat lets orb back into box.]

Orb: SHOOP

[Black Hat and Cueball stand next to laptop and box looking at them.]

856: Trochee Fixation

2014-06-19T13:01:55Z

108.162.216.37: /* Explanation */ no, the final list of words has the same stress pattern

{{comic
| number = 856
| date = February 4, 2011
| title = Trochee Fixation
| image = trochee fixation.png
| titletext = If you Huffman-coded all the 'random' things everyone on the internet has said over the years, you'd wind up with, like, 30 or 40 bytes *tops*.
}}

==Explanation==
{{incomplete|The words she says at the end are not explained. And on top of that, who is she?}}
A {{w|trochee}} is a type of {{w|metric foot}}. A foot is a measure in poetry, it consists of stressed beats and unstressed beats. A trochee is a foot which consists of one stressed beat followed by unstressed beat: "trochee" itself is an example of this as you stress the first syllable and don't stress the second syllable ("TROH-kee".) In the comic, a young girl develops a fixation with words that are trochees, such as robot ("ROH-bot",) raptor ("RAP-tor",) and Jesus ("JEE-zus".) [[Megan]] explains her behaviour. She proposes a "radical trocheeotomy." [[Cueball]] misinterprets Megan's intent as a "{{w|tracheotomy}}", but agreeing with the idea.

There are references to {{w|Teenage Mutant Ninja Turtles}} and {{w|Mighty Morphin' Power Rangers}}, both of which are examples of actual, trochaic TV show titles. Additionally, there is a reference to sci/fi author {{w|Neal Stephenson}} who has written {{w|Snow Crash}}, {{w|Anathem}} and many other books.

"Jetpack ferret" could be a reference to [[20: Ferret]] although this ferret just have wings.

{{w|Huffman coding}} is a lossless data compression algorithm that works by recording a specific string and then only recording that the string is repeated a certain number of characters later on until eventually it only contains a "dictionary" of unique substrings and then mentions of where those substrings repeat. In highly repetitive data this can cut down the file size immensely, which is what Randall is implying by saying you would only end up with 30–40 bytes. Most of the "random" stuff said on the Internet has been said before.

Trochee and other types of poetry "feet" is the subject of [[1383: Magic Words]].

:Girl: Robot ninja! Pirate doctor laser monkey! Narwhal zombie badger hobo bacon kitty captain penguin raptor Jesus!

:Megan: We'd been seeing this brain damage for years, but only recently did our linguists identify the pattern behind it.

:Megan: The patients fixate on animals and types of people whose names are trochees (two syllables, with the accent on the first).

:The malfunction causes a rush of dopamine whenever these trochees are heard or spoken.
:[Chart shows "internet" and "brain," with arrows marked "trochees" traveling both ways between them. An arrow marked "dopamine" loops from the brain back to the brain.]

:The warning signs appear in childhood:
:[Child sits in front of TV.]
:Child: Yeah! Mighty teenage morphin' ninja power mutant turtle rangers!
:Social reinforcement focuses the fixation on a few dozen words.
:Cueball (off-panel): Is there a cure?

:[Girl is reclining under a big machine pointed at her face.]
:Megan: We're about to try a radical trocheeotomy.
:Cueball: Rip out her vocal chords? I'm in favor.
:Megan: No, we're modifying her vocabulary* to erase the words she's fixated on.
:<nowiki>*</nowiki>Digitoneurolinguistic hacking! It's totally real! Ask Neal Stephenson.

:Megan: Either the gap will be filled by normal words, or she'll just generate a new set of trochees.
:Megan: Here goes.
:[She pulls the lever on a large panel.]
:''kachunk bzzzZZZZZZ''
