==Explanation==&lt;br /&gt;
{{incomplete|May require explaining the activities shown, as in the explanation for [[1141: Two Years]].}}&lt;br /&gt;
[[Randall]]'s wife was diagnosed with cancer in late 2010, a matter he has discussed in the comic [[:Category:Cancer|multiple times before]]. Here, motivated by the seven-year period between the American solar eclipses of {{w|Solar eclipse of August 21, 2017|2017}} and  {{w|Solar eclipse of April 8, 2024|2024}}, we see them reminiscing the seven years prior to the first eclipse, leaving an open question to what the next seven years will bring.&lt;br /&gt;
&lt;br /&gt;
This comic is a continuation of [[1141: Two Years]], which is shown as the first eight panels, slightly grayed out.&lt;br /&gt;
&lt;br /&gt;
Some explanations:&lt;br /&gt;
&lt;br /&gt;
*Panels 1–8: See [[1141: Two Years]]&lt;br /&gt;
*Panel 9: Randall and Randall's wife (with her hair noticeably longer than it was at the end of 1141) are walking through a forest.&lt;br /&gt;
*Panel 10: Randall's wife is sitting down, not in the forest anymore. She is concerned because she has pain in her toe and worries that this is an early sign of her cancer spreading again. Randall points out the simpler explanation- that she stubbed her toe the previous day, and the pain is likely a result of that. This panel shows the paranoia that comes from cancer remission, as earlier explained in [[931: Lanes]].&lt;br /&gt;
*Panel 11: Randall and his wife are going spelunking. The guide is gesturing deeper into the cave while Randall and his wife are climbing down.&lt;br /&gt;
*Panel 12: Randall's wife stands on a rock above an alligator in a swamp, photographing the alligator. Randall, on a balcony behind safety railings, observes that medical predictions about the odds of someone surviving cancer generally assume that the cancer patient doesn't risk something ''else'' killing them first.&lt;br /&gt;
*Panel 13: Randall's wife sits on an examination bed, listening to a doctor holding a clipboard. The doctor talks about an issue which is &amp;quot;probably nothing&amp;quot; but ''might'' be the cancer -- again showing the paranoia that comes with cancer.&lt;br /&gt;
*Panel 14: Randall and his wife stand above a deep pond full of fish and other objects. Randall's wife is piloting a wired underwater camera with lights. Randall shared pictures of his [https://blog.xkcd.com/2010/11/05/submarines/ underwater ROV] before.&lt;br /&gt;
*Panel 15: Randall and his wife are standing next to each other. Randall's wife has shoulder-length hair covering most of her face, and observes that, despite the chemotherapy robbing her of most of her hair six years ago, it is now growing enough to obscure her face. &amp;quot;The little girl from ''The Ring''&amp;quot; refers to {{w|Sadako Yamamura}}, the antagonist of the {{w|Ring (novel series)|''Ring'' series}} by {{w|Koji Suzuki}}, and popularized in a {{w|The Ring (2002 film)|2002 movie}}.&lt;br /&gt;
*Panel 16: A line of six people, including Randall and his wife, stand and watch the total solar eclipse of 2017, of which there have been [[:Category:Total Solar Eclipse 2017|several comics already]].&lt;br /&gt;
*Panel 17: The sky has been brightened, and the eclipse is over. As the eclipse is [[1880: Eclipse Review|cool to see in person]], the onlookers are left with little more than exclamations of amazement.&lt;br /&gt;
*Panel 18: Randall and his wife are walking together and holding hands. When his wife inquires about the next total eclipse, Randall replies that the next one is in seven years, and asks whether they should go to see it.&lt;br /&gt;
*Panel 19: Still walking, Randall and his wife think together about a timeline. Seven years have passed since 2010, represented with a solid line from the past to 2017; seven years in the future will be 2024, represented with a dotted line into the future and surrounded by three question marks. This is reflective of Panel 6, where &amp;quot;next year&amp;quot; is not guaranteed to be a thing.&lt;br /&gt;
*Panel 20: The pair keeps walking, optimistically agreeing to make their every effort to see the next eclipse.&lt;br /&gt;
&lt;br /&gt;
The title text is a continuation to panel 15 concerning the horror movie ''The Ring''. Specifically, watching the videotape in ''The Ring'' is supposed to kill a person in seven days, but the title text instead says &amp;quot;seven years&amp;quot;.&lt;br /&gt;

&lt;br /&gt;
:[Randall's wife sits on an examination bed, listening to a doctor holding a clipboard.]&lt;br /&gt;
:Doctor: This is probably nothing. &lt;br /&gt;

I feel it should be noted that these are good dogs, Brent. --[[Special:Contributions/108.162.246.17|108.162.246.17]] 04:49, 30 November 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
I think the good dog part in the title text is related to the [https://topatoco.com/collections/jeph-jacques/products/dogs-are-good-shirt new t-shirt from Questionable Content]. I think there has been guest comics one way or the other before. [[Special:Contributions/162.158.134.220|162.158.134.220]] 06:25, 30 November 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
It's different and probably unrelated, but the comic made me think of the science fiction classic _A Fire Upon The Deep_ in which there are intelligent hive mind dog packs. One dog isn't intelligent, but put 4-6 together and the pack forms a single person with human-level intelligence. [[Special:Contributions/141.101.104.155|141.101.104.155]] 07:52, 30 November 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
: The latest research shows you'd need about 30 dogs to equate to one human in terms of neuron quantity (https://newatlas.com/dogs-smarter-cats-neuron-density-study/52416/), but I wouldn't expect human-level intelligence with just 30 dogs because that ignores the amount of overhead needed to control the 30 dog bodies. [[Special:Contributions/198.41.238.40|198.41.238.40]] 11:20, 30 November 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
A large bark does not prove a large dog - dog size and bark size are not proportionately related.  The fact that the bark is apparently emanating from mid-air would be more of an indication (though this could be an auditory illusion caused by the combination of barks from the two dogs).[[Special:Contributions/141.101.104.239|141.101.104.239]] 09:37, 30 November 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
While I get the gist of the comic, my borderline completionism won't let me completely enjoy it unless I can understand the logical connection between astronomy and dogs. How are dogs and telescopes isomorphic in the realm of interferometry? Just another random brilliant leap that only makes sense to Beret Guy (i.e., not logical to any other being on Earth)? --[[Special:Contributions/108.162.221.136|108.162.221.136]] 14:53, 30 November 2017 (UTC)&lt;/div&gt;</summary>

This comic is a reference to the six-word short story {{w|For sale: baby shoes, never worn}}, which has been attributed to famous author {{w|Ernest Hemingway}}, however, [[Randall|Randall Munroe]] explicitly states that this might not be the case at all. The comic plays on the fact that the original story takes the form of a short advertisement that might have been seen in a newspaper, and puts it in a more modern form as titles of products from websites like Amazon and Craigslist.&lt;br /&gt;

A {{w|Compiler|compiler}} is a program that converts code into machine instructions that a computer can run. A {{w|Pointer (computer programming)|Pointer}} is a {{w|Variable (computer science)|variable}} within a computer program that is used to reference a memory location. A {{w|Segmentation Fault|Segmentation Fault (segfault)}} is an error that occurs when a program attempts to access an invalid section of memory. Segfaults usually cause a program to crash in an ungraceful fashion and fixing them can be difficult.&lt;br /&gt;

In the comic, the computer starts talking to [[Cueball]] and compares a segfault with the unpleasant feeling one gets when they experience a {{w|Hypnic jerk|hypnic jerk}}. The computer then tells the programmer to &amp;quot;double-check your damn pointers,&amp;quot; as segfaults usually arise from a program attempting to access memory that is referenced by an invalid pointer.&lt;br /&gt;
&lt;br /&gt;
The title-text references GNU-style {{w|autoconf}} configuration scripts. These scripts check certain features of the system they're running on in order to build a program correctly; for example, certain systems expect system calls to occur in a specific way, and the autoconf script will detect this and alter the program to match the expectation. Invariably (and memetically), these scripts include a check to determine &amp;quot;whether the build environment is sane.&amp;quot; This actually checks whether the path to the current folder has &amp;quot;unsafe&amp;quot; characters, and whether a newly created file is older than the script itself, which could indicate a very esoteric filesystem, a corrupted source archive, or just a system clock that's set incorrectly; however, since these file modification dates are an important part of how the autoconf script does its work, it can't go any further in an &amp;quot;insane&amp;quot; environment. In any case, the joke is that an insane build environment is nothing like an insane person, yet Randall is equating the two.&lt;br /&gt;

According to Wikipedia, the 1st and 2nd gen MagSafe connectors in this image are swapped: What Randall labeled as MagSafe 1 is actually MagSafe 2 and vice-versa. [[User:Mezgrman|Mezgrman]] ([[User talk:Mezgrman|talk]]) 10:31, 11 August 2014 (UTC)&lt;br /&gt;
:No, this isn't talking about generations, it's talking about actual connections. The ''MagSafe'' adapter was first developed with what Apple calls the &amp;quot;T&amp;quot; style form factor, then was aesthetically updated to the &amp;quot;L&amp;quot; style, which is labeled as &amp;quot;MagSafe&amp;quot; in the comic. The two form factors were interchangeable due to the actual connection and power flow being identical. ''MagSafe 2'' has returned to the &amp;quot;T&amp;quot; style, and was introduced with the Retina Display and newer MacBook Air models, and has a longer, thinner profile that is NOT interchangeable with regular MagSafe adapters, though a small adapter is available.

The one gender changer that bag won't have is the one for Token Ring... of all the adapters this thing can handle, I believe the Token Ring one is the only one without a gender -- one Token Ring plug plugs into another, or into the wall socket, etc. without needing to worry about whether you have a male connector or a female one.

; Diesel .v. petrol nozzles&lt;br /&gt;
&lt;br /&gt;
&amp;quot;A standard diesel nozzle is a bit thicker than a standard petrol nozzle so you cannot tank diesel into a petrol car but if this nozzle has the petrol nozzle diameter you are still able to tank with it into a diesel car.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
This statement may be true in some countries, but not here in the UK, for standard pumps for&lt;br /&gt;
use with normal cars, vans, etc. That said, we also have separate, high speed, pump nozzles for lorries (=trucks :-) ) which are quite a bit larger than the standard petrol/diesel nozzle. [[Special:Contributions/141.101.98.214|141.101.98.214]] 08:16, 12 August 2014 (UTC)&lt;br /&gt;
: It is true in UK as well, the sizes are the same all over the world as it is standardized by SAE. Although there are large nozzles for trucks (usually 1 1/3&amp;quot; or 1 1/2&amp;quot;; also they don't stop filling automatically), even the one for cars is a bit larger than the petrol one (diesel has 15/16&amp;quot; diameter, petrol 13/16&amp;quot;). If you have a petrol-running car, you can easily check this :-) Interestingly, there used to be 15/16&amp;quot; nozzle for petrol as well but that was used for leaded only. And yes, the smaller size was introduced to avoid tanking leaded petrol into an unleaded-only car (Patent US4034784), not to avoid tanking diesel.

Also, he's missing a lot of fiber/fibre connections (think FDDI, Fibre Channel, ST, LC, MT, SC, MIC, ESCON, TOSLINK, etc. :-)!  He's missing whatever weird connectors were/are used for T-1 feeds.  Also, is that parallel port DB-25 or Centronics 36?  Note that SCSI has been seen to go over Centronics 36, DB-25, a 50-pin ribbon connector, 68 or 80 pin ribbon connectors that were shaped like a DB connector to key them, Fibre Channel (mentioned before), and SAS.  Does the kit come with terminators?  Better yet, for some SCSI drives, does it come with those little fiddly 8 or 9 pin terminating resistor packs that slid into plugs on the drive?  Also, I wonder if you can run whatever weird protocol that 3270 terminals used over that F-connector and use this adapter like an IRMA board between an iPhone and a raw mainframe feed (no Microsoft SNA Server required).

According to Wikipedia, the 1st and 2nd gen MagSafe connectors in this image are swapped: What Randall labeled as MagSafe 1 is actually MagSafe 2 and vice-versa. [[User:Mezgrman|Mezgrman]] ([[User talk:Mezgrman|talk]]) 10:31, 11 August 2014 (UTC)&lt;br /&gt;
:No, this isn't talking about generations, it's talking about actual connections. The ''MagSafe'' adapter was first developed with what Apple calls the &amp;quot;T&amp;quot; style form factor, then was aesthetically updated to the &amp;quot;L&amp;quot; style, which is labeled as &amp;quot;MagSafe&amp;quot; in the comic. The two form factors were interchangeable due to the actual connection and power flow being identical. ''MagSafe 2'' has returned to the &amp;quot;T&amp;quot; style, and was introduced with the Retina Display and newer MacBook Air models, and has a longer, thinner profile that is NOT interchangeable with regular MagSafe adapters, though a small adapter is available.

; Diesel .v. petrol nozzles&lt;br /&gt;
&lt;br /&gt;
&amp;quot;A standard diesel nozzle is a bit thicker than a standard petrol nozzle so you cannot tank diesel into a petrol car but if this nozzle has the petrol nozzle diameter you are still able to tank with it into a diesel car.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
This statement may be true in some countries, but not here in the UK, for standard pumps for&lt;br /&gt;
use with normal cars, vans, etc. That said, we also have separate, high speed, pump nozzles for lorries (=trucks :-) ) which are quite a bit larger than the standard petrol/diesel nozzle. [[Special:Contributions/141.101.98.214|141.101.98.214]] 08:16, 12 August 2014 (UTC)&lt;br /&gt;
: It is true in UK as well, the sizes are the same all over the world as it is standardized by SAE. Although there are large nozzles for trucks (usually 1 1/3&amp;quot; or 1 1/2&amp;quot;; also they don't stop filling automatically), even the one for cars is a bit larger than the petrol one (diesel has 15/16&amp;quot; diameter, petrol 13/16&amp;quot;). If you have a petrol-running car, you can easily check this :-) Interestingly, there used to be 15/16&amp;quot; nozzle for petrol as well but that was used for leaded only. And yes, the smaller size was introduced to avoid tanking leaded petrol into an unleaded-only car (Patent US4034784), not to avoid tanking diesel.

Also, is that parallel port DB-25 or Centronics 36?  Note that SCSI has been seen to go over Centronics 36, DB-25, a 50-pin ribbon connector, 68 or 80 pin ribbon connectors that were shaped like a DB connector to key them, Fibre Channel (mentioned before), and SAS.  Does the kit come with terminators?  Better yet, for some SCSI drives, does it come with those little fiddly 8 or 9 pin terminating resistor packs that slid into plugs on the drive?  Also, I wonder if you can run whatever weird protocol that 3270 terminals used over that F-connector and use this adapter like an IRMA board between an iPhone and a raw mainframe feed (no Microsoft SNA Server required).

&lt;br /&gt;
A retroreflector is a device or surface that reflects light back at its source. The Apollo 11, 14 and 15 moon missions placed several such devices on the surface of the Moon to help scientists on Earth measure the distance between the two bodies using laser ranging.&lt;br /&gt;
&lt;br /&gt;
In the comic, two people are engaging in a battle with laser guns. One appears to gain the upper hand as he jumps on a desk, as the other's shot goes wide. He delivers the classic line &amp;quot;Any last words?&amp;quot; and is answered with the confusing phrase &amp;quot;Apollo retroreflectors&amp;quot;. The earlier wild shot, reflected off the moon, promptly lances down from space and hits him in the back.&lt;br /&gt;

A retroreflector is a device or surface that reflects light back at its source. The Apollo 11, 14 and 15 moon missions placed several such devices on the surface of the Moon to help scientists on Earth measure the distance between the two bodies using laser ranging.&lt;br /&gt;
&lt;br /&gt;
In the comic, two people are engaging in a battle with laser guns. One appears to gain the upper hand as he jumps on a desk, as the other's shot goes wide. He delivers the classic line &amp;quot;Any last words?&amp;quot; and is answered with the confusing phrase &amp;quot;Apollo retroreflectors&amp;quot;. The earlier wild shot, reflected off the moon, promptly lances down from space and hits him in the back.&lt;br /&gt;
