173.245.56.186:

Should it be noted that the Pikachu is drawn without its tail? It would normally a have lightning bolt shaped tail that appears to the side or from behind its head. (Trivia or other note?) [[User:Azule|Azule]] ([[User talk:Azule|talk]]) 15:22, 24 April 2015 (UTC)

In Pokemon games from Gold and up, pokemon are able to hold items, including pokeballs. While in the game, once a pokeball is filled it is no longer available to select as an item, this comic would seem to imply the possible 'inception' scenario of having a pokemon hold an active pokeball (as the games have already shown that a pokeball can go into a pokeball). --[[Special:Contributions/173.245.54.193|173.245.54.193]] 14:13, 24 April 2015 (UTC)
: ahem... "pokeception" short for "pocket inception" - I can't be the first one to coin this (?) - [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 16:33, 24 April 2015 (UTC)

Is the alt text a reference to double-yolkers (eggs with two yolks)? [http://www.bbc.co.uk/news/magazine-16118149 They're only about 1 in every 1000] but it seems like an obvious reference. --[[User:Fenn|Fenn]] ([[User talk:Fenn|talk]]) 08:32, 24 April 2015 (UTC)
:Makes sense to me. I didn't even think of double yolks until you mentioned it here. [[Special:Contributions/173.245.50.89|173.245.50.89]] 09:04, 24 April 2015 (UTC)BK201

:::I'd think it's a reference to the rate of twins, which is currently almost exactly 1/30 (and on the rise) [http://en.wikipedia.org/wiki/Twin#Statistics] [[Special:Contributions/173.245.56.186|173.245.56.186]] 17:45, 24 April 2015 (UTC)Merkky[[Special:Contributions/173.245.56.186|173.245.56.186]] 17:45, 24 April 2015 (UTC)

The explanation currently says that doubling makes it uncountably infinite. I'm pretty sure that doubling at each step (or every few steps) is still a countable infinite set. Proof here: http://practicaltypography.com/the-infinite-pixel-screen.html (see section "The internet demands a recount", because the first attempt is wrong). We can also prove it using the same argument as when proving that N x N is countable infinite (making zig-zag), but in this case making a breadth-first search of the tree of Pikachus: map 1 to the first Pikachu, map 2 and 3 to the two Pikachus at the second level, map 4, 5, 6, 7 to the four Pikachus at the third level, map (2^(n-1))…((2^n) - 1) to the 2^(n-1) Pikachus at level n. {{unsigned ip|108.162.229.177}}
:Saw this too late. Yes, I agree, and I have fixed it accordingly. --[[User:Stephan Schulz|Stephan Schulz]] ([[User talk:Stephan Schulz|talk]]) 09:28, 24 April 2015 (UTC)
:The problem being that we don't have an exact number for how many steps include double Pikachus. Granted, this is just a problem of practice, not theory. [[Special:Contributions/173.245.50.88|173.245.50.88]] 12:37, 24 April 2015 (UTC)

"infinite, but countable" {Cough.} Someone doesn't understand infinity. Perhaps they meant "enumerable". [[Special:Contributions/108.162.250.155|108.162.250.155]] 09:29, 24 April 2015 (UTC)

::enumeration is counting, in the simplest sense. "To name one by one; specify, as if in a list".

"The front most Pikachu speaks." Hey, look, it has those little lines to show it's speaking, not the blank white space behind it. Duh. [[Special:Contributions/108.162.250.155|108.162.250.155]] 09:32, 24 April 2015 (UTC)

Looks like Megan is looking at her watch as well. Mention in transcript/explanation? [[User:Fenn|Fenn]] ([[User talk:Fenn|talk]]) 09:34, 24 April 2015 (UTC)
:Are Megan and Cueball supposed to fight each other? It seems like Cueball still has his closed Pokéball in his hands. Is it then Megan's Pokéball that has evolved into all these Pikachu? And is it because she waits for her Pokémon to be ready to fight Cueball, that she checks her watch? I do not know anything about the Pokémon game/world. But it seems to me that some part of this setup is unexplained by the above... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 11:23, 24 April 2015 (UTC)

Friendly reminder: Grammatically speaking, Pokémon are like sheep or deer. Singular and plural are both written the same. One Pikachu, many Pikachu, all the Pikachu. You'd be surprised at how much rage forgetting this causes in certain corners of the Internet. {{unsigned ip|141.101.99.42}}

What doesn't make sense to me is how this could continue indefinitely – after all, each of those Pikachu must have caught its own Pikachu beforehand. I don't see any infinite loop here, just a bunch of Pikachu that already had one another caught itselves. [[Special:Contributions/141.101.96.217|141.101.96.217]] 10:13, 24 April 2015 (UTC)

The word "induction" could also be intended to have a double meaning, referring also to electromagnetic induction. Pikachu is, after all, and electric pokémon. {{unsigned ip|141.101.105.194}}
:Yes, I think this is right. Something about Maxwell's equations and induction. {{unsigned ip|173.245.54.203}}
::From an engineering standpoint, in my opinion, Pikachu act more like biological capacitors (stored electric charge at potentially high voltage able to deliver large discharge currents) than inductors ("storing" magnetic energy via constant current, able to deliver high voltage when interrupted, like the ignition coil for an older automotive engine). I'm not too familiar with the Pokémon in-game/in-show universe, but I would imagine the Nurse Jenny corps could use electric Pokémon such as Pikachu (or Raichu) like defibrillators for cardiac events! --BigMal // [[Special:Contributions/173.245.50.177|173.245.50.177]] 11:42, 24 April 2015 (UTC)
:::There are certain moves, including some that Pikachu can learn, that appear to be based on induction (Thunder Wave and Shock Wave). Besides, they build up charge in their bodies from somewhere; I'd suspect induction from the surrounding environment is what charges them up. --[[Special:Contributions/188.114.110.52|188.114.110.52]] 14:34, 24 April 2015 (UTC)

There's a point floating about how infinity doesn't imply completion. For instance, the number of all even integers is infinite, yet any given integer "only has a 50% chance of being even", so the series is quite obviously incomplete. This article seems to tend towards the idea (in diction) that an infinite number of pikachu would result in a win based on a 'logical' premise, without referring specificially to the terms of it's assumption. [[User:Xerxesbeat|Xerxesbeat]] ([[User talk:Xerxesbeat|talk]]) 11:38, 24 April 2015 (UTC)

What happens if the Pikachu in the ball is recursing - picking himself? That doesn't fit the 30-40 double yolk thing, but would explain an infinite series. Food for thought. Megan is bored, waiting for the fight to start. I thought the game was supposed to begin when the players choose, though, so I don't understand why the wait is happening at all.

I doubt this is an intentional part of the joke, but the strongest Ground-type moves (Earthquake, Precipice Blades, etc.) are multi-target, hitting all foes in a 1v5 situation such as Horde Battles. In theory, a strong enough super effective move from Cueball's lead would still end the battle in one turn. [[Special:Contributions/173.245.56.176|173.245.56.176]] 12:04, 24 April 2015 (UTC)
:Not Land's Wrath, Dig, or Earth Power, which are strong ground-type moves.[[Special:Contributions/173.245.48.126|173.245.48.126]] 13:05, 24 April 2015 (UTC)
::Actually, Land's Wrath is multi-target. (The ones you named are also weaker than Earthquake and Precipice Blades, so the original comment stands regardless. Although a lucky Magnitude is more powerful than any of those.) --[[Special:Contributions/108.162.221.98|108.162.221.98]]

I normally get a hearty chuckle out of Randall's graphical musings, but this one had me scratching my head. Fortunately, ExplainXKCD always comes to the rescue! After reading this page, my first thought was: Pokéception! 13:17, 24 April 2015 (UTC)

== Induction ==

Two other possibilities: one, in a bit of googling, it would appear that there is a type of Pokémon evolution called induced evolution, which involves stones of some kind? Alternately, we can use the term induction in the sense of soneone being ''inducted'' into a group. In this case, Megan has trained her Pikachu to be a Pokémaster. (Perhaps by arranging for it to be inducted into a rarified "gym"? I confess, I know nothing about the show.) [[Special:Contributions/173.245.56.196|173.245.56.196]] 13:11, 24 April 2015 (UTC)

I'm surprised no one mentioned that Pokémon is a game a long time before becoming a show. Although it was because of the animated series that Pikachu became "special" among the hundreds of other cute critters.

Also, no mention to the russian matryoshka dolls? Come on...
Closest other xkcd I recall is https://xkcd.com/878/

== Axiom of choice ==

Could this be to do with the {{w|axiom of choice}} from set theory? From my understanding, it's a fundamental axiom of set theory that says 'given a set of sets, it's possible to choose one element from each of those sets'. "Choosing" is in this case a specific operation that can be performed on an element.

One specific detail about the axiom is that all sets under consideration must be nonempty; that is, they must contain at least one element. So I think this is analogous to the situation of a Pokemon trainer owning multiple (full) Pokeballs: his Pokeballs are a collection of non-empty sets from which he is now trying to choose a single element ("Pikachu, I choose you!").

Under ''normal'' circumstances, he can do this without invoking the axiom of choice because he knows the names of all his Pokemon and so can select one from each set. In this case, he could prove his ability to make the choice simply by releasing all of his Pokemon from their balls one at a time. (The Pokemon's name is actually irrelevant, because simply releasing the Pokemon counts as a choice).

However, the situation becomes more complex if it turns out that his Pokemon also possess Pokeballs, because now his ability to make the choice is uncertain. In this situation, there could be ''infinitely many'' Pikachus, and so he can't definitely select a Pikachu from all the Pokeballs under his control. In a situation like this, a mathematician would invoke the axiom of choice.

However, it seems that Cueball is actually having a go at it using an inductive method of choice: first by choosing a Pikachu, then having each Pikachu choose a Pikachu. If the number of Pikachus carrying Pokeballs is finite, then eventually, this will demonstrate that the choice can be made and so the axiom of choice is unnecessary. However, if it's ''infinite'', then this will generate a neverending stream of Pikachus. In the latter case, the game never begins, because you can't begin a Pokemon battle until all participants have chosen Pokemon. Most likely, the other players would simply abandon the game, which Cueball could claim as a victory. [[User:Hawthorn|Hawthorn]] ([[User talk:Hawthorn|talk]]) 13:52, 24 April 2015 (UTC)

1461: Payloads

173.245.56.186: /* Explanation */

{{comic

| date = December 17, 2014

| image = payloads.png
| titletext = With a space elevator, a backyard full of solar panels could launch about 500 horses per year, and a large power plant could launch 10 horses per minute.

==Explanation==
{{incomplete|Still probably incomplete, but I don't know why. I just removed the "CREATED BY A BOT" message, because since then, it has been edited by a human.}}
This comic lists the payload capacity of several launch vehicles, and the mass of several spacecraft, in number of horses. This could be related to Randall's hobby of abusing dimensional analysis, as horses/ship is technically a perfectly acceptable derived unit, provided the size of a horse is standard (in this comic it appears that 'One Horse' is defined as 450kg). In cases where the mass is less than one Horse, an alternative measure of Dogs has been used, where one Dog appears to be roughly 40kg. In the case of {{w|Vanguard 1}}, even a Dog is too large a measure, so instead the unit Squirrel is used to represent its 1.47kg mass.

The overall comic is an allusion to {{w|horsepower}}, a similar-sounding but completely different concept. Horsepower is a measurement of {{w|power (physics)|power}} ({{w|work (physics)|work}} per unit time). Another commonly referenced unit for power is the {{w|watt}}. 1 horsepower is meant to be approximately the amount of power a horse can deliver. In contrast, Randall uses the horse to measure {{w|mass}} (of spacecraft themselves, and of the payload they carry).

The top pane of the comic shows the mass of various spacecraft, while the bottom shows the amount of mass they can deliver to {{w|low earth orbit}}. There are also several joke insertions. In the top, one is T-Rex. In the bottom, another is Pegasus (the payload capacity given as one Pegasus); this is a reference to both Pegasus {{w|Pegasus (rocket)|the rocket}} and Pegasus the {{w|Pegasus|mythical flying stallion}}. The bottom also gives the 1981 {{w|Oldsmobile}} as 4 horses; presumably, this is actually the number of horses the Oldsmobile could tow, rather than launch into low earth orbit.

The Pegasus, 1981 Oldsmobile, and Stratolaunch spacecraft are depicted horizontally, presumably because these vehicles launch from a horizontal starting position and use forward momentum to facilitate their launch.

There is an unlabeled launch vehicle below the H-11A near 2002. The unlabeled vehicle has a playload mass of 21 horses (8540 kg).

Guacamole = 7-layer dip ingredient

Seventh Seal more likely to be a reference to Book of Revelation (I think he's brought it up before?) or the film? [[Special:Contributions/199.27.133.96|199.27.133.96]] 05:17, 5 September 2014 (UTC)

Arctic Ocean is one of the modern Seven "Seas" of the world.
Green is the 4th color of seven in the Arthur Hamilton song "I Can Sing a Rainbow". {{unsigned ip|108.162.249.212}}

I guess the title text is a play on the fact that the dwarves in the new Snow White (2001) movie are called Monday, Tuesday, ... That is the connection between Snow White dwarves and days of the week. The filmmakers decided to intermix sets of seven in the first place.

There could be a pattern with order.

*Sneezy: 1st dwarf of the seven dwarves in Snow White.
*Phylum: 2nd rank in the Seven Taxonomic Ranks
*Europe: 3rd continent of the world
*Sloth: 4th sin of the Seven Deadly Sin
*Guacamole: 5th Layer in a 7 Layer Bean Dip
*Data Link: 6th Layer in the OSI Model
*Collosus of Rhodes: 7th Wonder of the Ancient World

*Monday: 1st Day of the Week (American).
*Arctic: 2nd ocean in the modern Seven "Seas" of the world.
*Wellesley: 3rd college of the Seven Sister colleges
*Green: 4th color in the Arthur Hamilton song "I Can Sing a Rainbow".
*Electra: 5th sister of the Pleiades, the Seven Sisters.

I've always been told there are only six continents. North America and South America are one continent. The seventh continent sometimes refers to this gigantic area filled with plastic rubbish in the Pacific Ocean. [[Special:Contributions/108.162.229.143|108.162.229.143]] 11:47, 5 September 2014 (UTC)
: See here: https://www.youtube.com/watch?v=3uBcq1x7P34 But no one talks about the Great Pacific garbage patch as a continent. 7 continents is the most common model, with some (mainly Latin Americans) considering the Americas a single continent. Some others consider Eurasia a single continent (personally that's what I prefer, it makes the most sense). --[[User:Zagorath|Zagorath]] ([[User talk:Zagorath|talk]]) 12:12, 5 September 2014 (UTC)
: I've only ever heard folks say there are seven continents. By strict definition of the word, North and South America do form a single continent (at least did prior to the Panama Canal cutting them apart) the vast majority of people see then as two separate continents. Dividing the Eurasian landmass in two, however, that one never made much sense. [[Special:Contributions/199.27.128.117|199.27.128.117]] 16:53, 5 September 2014 (UTC)

Guacamole may also be a reference to a famous joke which made the rounds about 15 years ago, where somebody had compared the 7 layers of the OSI network model to Taco Bell's 7-layer burrito. Guacamole was the 5th layer, which lends credence to this idea.

I find it interesting that although Randall is American he lists Monday as the first day of the week. That's where it's positioned in most cultures outside the USA, but Americans normally consider Sunday to be the first day. --[[User:RenniePet|RenniePet]] ([[User talk:RenniePet|talk]]) 13:51, 5 September 2014 (UTC)
: I can't speak for anyone outside the US, but as someone who has spent 99.9% of my life within US borders (few weeks in Canada, if you think that should essentially count...), I only acknowledge that the first day listed on any monthly calendar I see around here is most often Sunday. If you were to ask me what the first day of the week is, I would very quickly and easily say "Monday". That is what I'm teaching my 4- and 2-year olds... There are a few reasons I would give to explain that other than "I think of it as the first day of the week". It's the first work day of the "work week", and since life is for most people centered around one form of work or another, that gives the "work week" high importance. By extension, Sunday is the last day in the "weekend". By Judeo-Christian beliefs, God rested on the "seventh" Day - most Christians believe that to be Sunday; others (I believe mostly Jewish) believe it to be Saturday - I think, though that even those who consider Saturday to be a holy day, if you were to ask them in casual conversation what the first day of the week is (I may be wrong, but), I think they would say "Monday"... (?) Any other "Americans" or "Non-Americans" (I'd ask for you to clearly identify with one or the other) want to weight in on this? - [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 15:51, 5 September 2014 (UTC)
::I can't really comment on anything talked about by Brettpeirce, but I can say a few words about the "first day of the week" problem as seen by a computer programmer. It causes huge problems when your program displays a calendar because you have to take into account that Americans want it one way and most other people want it a different way. And supposedly simple things like scheduling an appointment "first work day next week" has a completely different result if it is done on a Sunday in the USA or on a Sunday in Europe. And then there's the problem of week numbers (used a lot in Europe but not so much in the USA). Week numbers depend on which week is designated as the first week of the year, which in most countries is defined as the first week with at least 4 days in the year. Now if January 3rd is Sunday, then in the USA it is the start of week 1, while in Europe it is the last day of the last week of the previous year (week 52 or 53). It's enough to drive you to drink (which is OK on Sunday some places but not others). --[[User:RenniePet|RenniePet]] ([[User talk:RenniePet|talk]]) 20:36, 5 September 2014 (UTC)
:::Oh, and then there are the incompatibilities in programming languages. American-developed computer languages like C and Basic and C++ and C# number the week days 0 - 6 meaning Sunday - Saturday. Meanwhile Java numbers week days 1 - 7 meaning Sunday - Saturday, except that the newest version, Java 8, has improved data/time facilities, and if you use them then week days are numbered 1 - 7 meaning Monday - Sunday. --[[User:RenniePet|RenniePet]] ([[User talk:RenniePet|talk]]) 20:52, 5 September 2014 (UTC)

:The Dwarfs here are drawn somewhat off-model, with bigger noses than in Disney artwork. Perhaps someone is confusing the second figure's nose, which is drawn much larger than Dopey's, with Fievel's other ear.

1406: Universal Converter Box

2014-08-11T12:34:42Z

173.245.56.186: /* Different connectors */

{{comic
| number = 1406
| date = August 11, 2014
| title = Universal Converter Box
| image = universal_converter_box.png
| titletext = Comes with a 50-lb sack of gender changers, and also an add-on device with a voltage selector and a zillion circular center pin DC adapter tips so you can power any of those devices from the 90s.
}}

==Explanation==
{{incomplete|Needs explanation of each device and explanation of title text.}}
Converter boxes are used to connect two devices together which otherwise couldn't be, due to different shaped plugs, different voltages, or different protocols of communication.

Converter boxes or converter cables are commonly found for several of the plugs at the top of the list - such as from USB to micro-USB.

The humour from this comic comes from the progressively ridiculous conversions that this box is capable of doing, for example, converting audio from a 1/8inch / 3.5mm headphone jack, into a variety of petrols suitable for running your car.

===Different connectors===
*{{w|VGA_connector|VGA}} (Video Graphics Array): A type of video connector, it has fifteen pins in a D-shell (a trapezoidal metal skirt that protects the pins, prevents the connector from being plugged in the wrong way, and makes the physical connection more secure). First used in 1987, and with new versions being developed since then, it is an extremely common type of video connector.
*{{w|Digital_Visual_Interface|DVI}} (Digital Visual Interface): Another type of video connector, it also uses a D-shell connector, except the pins are flat instead of round. DVI is not compatible with VGA ports, though DVI can transmit an analog signal.
*{{w|HDMI}} (High Definition Multimedia Interface): A connector that can transmit both video and audio over the same cable, HDMI has slowly been replacing DVI and VGA ports on newer devices due to the simplicity (both audio and video in one connector) and the smaller footprint and overall dimensions.
*{{w|Thunderbolt_(interface)|Thunderbolt}}: A multimedia/data connector, Thunderbolt can transfer both video signals to a monitor, audio signals to speakers, and send and receive data at the same time, over the same port. However, the limited adoption by manufacturers, the higher costs of the hardware, and the security concerns inherent to the interface have limited the adoption by consumers.
*{{w|IEEE_1394|Firewire}} (IEEE 1394): A bidirectional data transfer connector, similar to USB, Firewire can be used for many applications (e.g. networking computers), but it mostly finds use connecting audio/video equipment to computers.
*{{w|Component_video|Component}} and {{w|RCA_connector|RCA}}: Both component video and RCA are ways of transmitting video and audio signals. Technically, RCA is the name of the connector type that they share; the "RCA" video connection is also called composite video. Both use two plugs for audio (left and right channels), but RCA (composite) uses one plug for video where component uses three.
*{{w|Phone_connector_(audio)|1/8" audio/video}} (3.5 mm phone connector): A very common type of connector, perhaps best known as a headphone plug, but also used for other audio equipment and (as the comic indicates) for some video equipment.
*{{w|Parallel_port|Parallel port}}: A now-obsolete computer interface, mostly used to connect printers to PCs.
*{{w|S-Video_(analog_video_standard)|S-video}}: Another video standard similar to component and RCA.
*{{w|In-flight_entertainment#History|Airline pneumatic tube audio}}: Connector for pneumatic headphones used by in-flight entertainment systems until 1979.
*{{w|PS/2_port|PS/2}}, PS/3 and PS/4: The PS/2 connector was used for mouse and keyboard connections in older computers; it has been superseded by USB. There are no such connectors as PS/3 and PS/4 -- the joke here is that the {{w|PlayStation 2}} console is also abbreviated to PS2, and there have been two models of PlayStation since, abbreviated PS3 and PS4.
*{{w|NEMA_connector|120V AC}}: This style of plug is used for domestic power outlets in the US, Canada, Mexico, and some other parts of the Americas. (Interestingly, while AC adapters are necessary -- and widely available -- to suit sockets in other countries, this "universal" convertor does not feature any other AC power plugs.) The pin marked "removable" is the ground pin; not every device requires a ground pin, and some (older) sockets do not have a hole for it.
*{{w|Floppy_disk|Floppy}}, {{w|Parallel_ATA|IDE}}, {{w|Hard_disk_drive|SFF-8212 (2.5")}}, {{w|SCSI_connector|SCSI}} ({{w|Ribbon_cable|Ribbon cables}}): These various disk drive connectors all use ribbon cables with different numbers of pins and the end, and hence different widths of cable. Despite this similarity, real plugs do not have break-away parts for different devices.
*{{w|USB#Connectors_and_plugs|USB}} connectors: This bidirectional data connection is used for connecting many different devices to computers, each other, and to power supplies and chargers. The USB standard has many different types of plugs, necessitating convertors like the one in the comic (though generally less featureful). The types present here are USB-A ("USB"), USB-B ("USB weird other end"), mini-USB, micro-USB, and the non-existent "macro-USB" (a joke on the previous two).
*{{w|F_connector|F connector}}: A type of coaxial plug used for various television signals and for cable modems.
*{{w|Optical_fiber_connector|Fiber}}: Optical fiber cables are used for various data transmission purposes. Interestingly, the fiber depicted does not seem to have any of the (many) typical optical fiber connectors; it may be simply a loose end.
*{{w|Registered_jack#RJ11.2C_RJ14.2C_RJ25_wiring_details|RJ11}}: The "smaller than RJ45" connector which is used for land-line telephones.
*{{w|Registered_jack#RJ45|Ethernet}} (RJ45): The most common consumer-grade fixed wire connection for computer networking.
*{{w|Token_ring|Token ring}}: A now-outdated networking technology, token ring was a late-80s competitor to Ethernet for fixed-wire network connection.
*{{w|MagSafe}}: Magnetically-attached power connectors used on Apple devices. The original MagSafe (introduced in 2006) was later replaced by MagSafe 2 (introduced in 2012); both come in "L" and "T" shapes (as shown here for MagSafe and MagSafe 2, respectively), but are incompatible. MagSafe 3 and 4 do not actually exist (yet). Also, the MagSafe 4 "connector" appears to be broken; this may be a joke about the poor quality of MagSafe cables.
*{{w|Bluetooth#Communication_and_connection|Bluetooth dongle}}: A wireless network standard mostly used to connect accessories to phones and computers.
*{{w|SCART}}: An audio/video connector mostly used in Europe; it replaced other connectors like component video, but has itself been superseded by HDMI.
*{{w|Tin_can_telephone|String}}: For connecting to a "tin can telephone", an analogue device for transmitting sound through a physical connection rather than electronically or via radio waves.
*{{w|Fuel_dispenser#Nozzles|Fuel nozzle}}, with a switch to choose between different {{w|Octane_rating|octane ratings}} and {{w|Diesel_fuel|diesel fuel}}: Dispensers for fossil fuels used to power internal combustion engines.

The title text is referring to connector "gender," which is a further complication in getting a connection. A connector is capable of making a connection to another device only through another connector of the opposite gender. Gender adapters flip the gender of a connector, so that two connectors of the same gender can connect. Due to the number of connections this box is capable of, there would be a significant number of connectors, which would lead to them weighing 50-lbs in all. The weight of the petrol pump gender adapter is probably responsible for the bulk of this.

The "circular center pin DC adapter tips" in the title text are barrel jack power plugs. These were developed in the 1980s, and come in a staggering variety of dimensions. The "barrel" has both an inner diameter and an outer diameter, so even if the outer diameter of the barrel jack (which can be easily measured) is correct, the inner diameter might not be. Furthermore, there is the complication that the device requires power at a certain voltage and the supply must provide the correct voltage, and the polarity also has to be correct: positive on the barrel and negative on the inner pin, or vice-versa. This leads to frustration on the part of users when the original power supply cannot be found.

Talk:713: GeoIP

173.245.56.186: hyperbole "+"

The title text is more than hyperbole: In the United States, if someone is "living in their mom's basement", it implies they can not or will not get a job allowing them to move out. i.e.: they are a loser. The resultant weak response "Screw you, GeoIP" seems to push that depiction even further. [[Special:Contributions/173.245.56.186|173.245.56.186]] 23:11, 16 July 2014 (UTC)
