==~*~Explanation~*~==&lt;br /&gt;
&lt;br /&gt;
The talk page of a Wikipedia article is used to discuss changes to the article. An {{w|Wikipedia:Edit warring|edit war}} is a dispute about a specific edit to an article, manifesting as a series of edits alternating between making and reverting the change, and usually accompanied by a more-or-less heated debate on the talk page.&lt;br /&gt;
&lt;br /&gt;
Here, [[Randall]] is referring to a dispute on the Wikipedia article about ''{{w|Star Trek Into Darkness|Star Trek lnto Darkness}}'' (an upcoming {{w|Star Trek}} film at the time of the comic's posting). On the day before the comic was published, the article name had a lowercase &amp;quot;into&amp;quot;, and the talk page looked [http://en.wikipedia.org/w/index.php?title=Talk:Star_Trek_Into_Darkness&amp;amp;oldid=535542349 like this] (rounded off in a friendly way, with the posting of {{w|User:Frungi/Star Trek Into Darkness capitalization|a summary of the arguments}}, and an exchange of virtual hugs). In summary, the debate centers around whether &amp;quot;Into Darkness&amp;quot; should be treated as a prepositional phrase or an unpunctuated subtitle (as in &amp;quot;Star Trek: Into Darkness&amp;quot;), whether compound prepositions like &amp;quot;into&amp;quot; should be capitalized in titles, and whether the capitalization of the title in the movie's official promotional material is relevant. The intensity and multiple facets of a debate over one tiny letter is apparently entertaining to Randall.&lt;br /&gt;
&lt;br /&gt;
[[Cueball]] changes the title so that every other letter is capitalized, and adds framing tildes and asterisks (a common, but childish and ugly way of emphasizing titles online). This will probably not go over well.&lt;br /&gt;
&lt;br /&gt;
[[Megan|Megan's]] line of &amp;quot;They should have sent a poet.&amp;quot; is a quote from the film ''{{w|Contact (1997 American film)|Contact}}''. The quote is also featured in [[482: Height]].  In the movie, the line was meant to convey that only a poet could adequately capture the beauty seen; here, it indicates that prose is insufficient to capture the ironic beauty of the edit war.&lt;br /&gt;
&lt;br /&gt;
The title text indicates Randall's belief that such arguments are perpetual and will always arise. He suggests that the edit to the Wikipedia page will result in a dispute over variants of Cueballs &amp;quot;compromise&amp;quot;. Because the lowercase &amp;quot;L&amp;quot; and the capital &amp;quot;I&amp;quot; appear similar in many fonts, he also puts forth the potential argument that the character in the movie's title is a lowercase &amp;quot;L&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
The old &amp;quot;favorite edit war&amp;quot; might be the one referenced in the title text of [[878: Model Rail]] or the one resulting from the addition of the [[739: Malamanteau]] article to Wikipedia&lt;br /&gt;

&lt;br /&gt;
:Cueball: Forty ''thousand'' words of debate over whether to capitalize &amp;quot;into&amp;quot; in the movie's title. Still no consensus.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
''{{w|The Family Circus}}'' is a comic characterized by single-pane round comics with a caption below the comic. Jeffy is a character in ''Family Circus'', and dotted lines representing his wanderings are a frequent theme of ''Family Circus'' comics. {{w|Obsessive-compulsive disorder}} (OCD) is a mental illness that compels the sufferer to perform repetitive actions. Common symptoms include, but are not restricted to, excessive hand washing and repeated opening and closing of a door.&lt;br /&gt;
&lt;br /&gt;
The comic depicts the character Jeffy as having Obsessive-Compulsive Disorder and traces his movements over a period of time. The dotted line that depicts his movements returns frequently to the kitchen sink, presumably to repeatedly wash his hands.&lt;br /&gt;
&lt;br /&gt;
In the title text, [[Randall]] attributes this idea to the unknown friend [[:Category:David|David]]. He did the same in [[42: Geico]] and [[51: Malaria]].&lt;br /&gt;
&lt;br /&gt;

{{incomplete|This was created by a TRUSTWORTHY CIRCULAR VIDEO. Nothing about Bold and Dynamic. Bad dubious template. Better explanation on horizontal and vertical needed. DO NOT DELETE THIS TOO SOON (It already was once.}}&lt;br /&gt;
&lt;br /&gt;
This comic compares different pros and cons of 3 video angles.&lt;br /&gt;
 &lt;br /&gt;
Horizontal angling	&lt;br /&gt;
1. Good for people not used to phones and has been used for centuries. (True)&lt;br /&gt;
2. Humans can’t be captured as well. (True if a full body shot is desired)&lt;br /&gt;
3. Can be uncomfortable to hold the smartphone when recording and viewing. (True)&lt;br /&gt;
4. It more accurately displays the way humans view the world: we view approximately 150 degrees horizontally and only 50 degrees vertically. (not stated in the comic)&lt;br /&gt;
	&lt;br /&gt;
Vertical angling  	&lt;br /&gt;
1. Is normal for most smartphone users. (True)&lt;br /&gt;
2. Can’t capture the background well. (True, when not used in panoramic view)&lt;br /&gt;
3. When the subject of the video is a human, it captures more of their body. (True)&lt;br /&gt;
4. Is less stressful on the hands of the one holding the mobile recording device. (True)&lt;br /&gt;
	&lt;br /&gt;
[[Randall]] does love a good [https://explainxkcd.com/690/ compromise], so he suggests the following angle:&lt;br /&gt;
	&lt;br /&gt;
Diagonal angling &lt;br /&gt;
1. Not a standard format of video {{Citation needed}} (True)&lt;br /&gt;
2. Equally annoying to all viewers (Almost certainly true)&lt;br /&gt;
3. Diagonal angling has no flaws, and is perfect in every way {{Dubious}}.  (False)&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
&lt;br /&gt;
This comic was published six days prior to the {{w|United States elections, 2018|2018 United States general elections}}, also called {{w|United States midterm election|midterm elections}}, because they happen halfway between two presidential elections, two years before and after. At the time, the [[xkcd]] header still provided a link to [https://www.vote.org/ vote.org], a website that helps US citizens with essential voting issues, like how to register or how to find their polling locations. It is the first of three consecutive comics that deal with this election. &lt;br /&gt;
&lt;br /&gt;
In the United States, &amp;quot;{{w|ballot selfie}}s&amp;quot; refers to the practice of taking a picture of oneself with a completed ballot. These have been illegal in many states, due to laws passed to prevent vote selling.&lt;br /&gt;
&lt;br /&gt;
Without proof of how a vote was cast, if someone bribed (or even violently coerced) a voter to vote for candidate A, the voter could just vote 'B' and the coercer would be unable to tell whether they voted as instructed.  This is at the heart of the concept of &amp;quot;a secret ballot&amp;quot;.  But if ballot-selfies or other proof-of-vote mechanisms are permitted then the evil-doer can demand verification that the voter did what they were coerced to do - and this jeopardizes the idea of a truly free and fair election.&lt;br /&gt;
&lt;br /&gt;
However, the &amp;quot;secret ballot&amp;quot; principle is not universally valued nor enforced. Some voting machines produce a paper receipt showing the choices the voter made - and many jurisdictions permit use of a postal ballot - so there are plenty of other ways to circumvent the law in those places.  So the ban on ballot selfies is harder to justify unless those other lines of coercion are also ruled out.&lt;br /&gt;
&lt;br /&gt;
On the other hand, the desire to take and distribute ballot selfies often comes from an excitement in participating in the voting process and the desire to share that excitement in the hopes of encouraging others to vote, and anything that helps get more people to the polls is generally considered to be a good thing. In addition, the law is incredibly difficult to enforce -- there is little way to prevent somebody from photographing their ballot and privately showing this photo to somebody else -- and the practice of enforcing it (i.e. searching for possible photographic devices all together) would make the local government incredibly unpopular.  Lastly, voters storing evidence of their votes could be useful to prevent voting fraud performed by the state.&lt;br /&gt;
&lt;br /&gt;
This dual threat/benefit has led some states to explicitly legalize ballot selfies, other states to specifically disallow them and even levy steep financial penalties, while the rest are still debating or ignoring the issue[https://www.vox.com/policy-and-politics/2016/10/25/13389980/ballot-selfie-legal-illegal].&lt;br /&gt;
&lt;br /&gt;
As [[Ponytail]] is aware of this law, she believes she has identified a solution wherein she will make an {{w|oil painting}} of her voting rather than taking a {{w|photograph}}.  A painting being more of an artistic endeavor that doesn't have to faithfully record all aspects of the image, it may well be valid both on grounds of {{w|freedom of speech}} as well as not being a verbatim record of her vote - thereby preserving the secrecy of the ballot.  Of course, making a painting of her vote may lead to additional problems. If she intends to paint the portrait herself, of herself (i.e. a {{w|self-portrait}}) casting her vote, it would be very difficult and time consuming to attempt to do that, especially without a mirror, which she apparently doesn't have with her and which is generally not standard issue in voting booths. She could also try to recruit someone else to do the painting, not knowing the level of their artistic talent, however, usually only the person casting the vote is allowed in the booth, and they are expected to close the curtain or otherwise ensure no outside person, like the painter, can view the vote casting act.&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Common Vulnerabilities and Exposures|CVE}} (Common Vulnerabilities and Exposures) is a standardized format for assigning an identity to a cybersecurity vulnerability (similar to the way that astronomical bodies are assigned unique identifiers by committees). Giving vulnerabilities a unique identifier makes them easier to talk about and helps in keeping track of the progress made toward resolving them. The typical format of a CVE identifier is '''CVE-[YEAR]-[NUMBER]'''. For example, the CVE identifier for 2017's widespread {{w|Meltdown (security vulnerability)|Meltdown vulnerability}} is [https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5754 CVE-2017-5754]. CVEs also contain a short description of the issue.&lt;br /&gt;
&lt;br /&gt;
In this comic (released in February 2018), Randall presents a number of spurious predicted CVEs for later in 2018. Each CVE identifier is given as &amp;quot;CVE-2018-?????&amp;quot;, reflecting the fact that they have not yet happened so we don't know exactly what their CVE identifier will be.&lt;br /&gt;
&lt;br /&gt;
Following are short descriptions of all the ''vulnerabilities'' mentioned in the comic.&lt;br /&gt;
&lt;br /&gt;
;Apple products crash when displaying certain {{w|Telugu language|Telugu}} or {{w|Bengali language|Bengali}} letter combinations.&lt;br /&gt;
:This refers to a [https://techcrunch.com/2018/02/15/iphone-text-bomb-ios-mac-crash-apple/ real vulnerability] in iOS and MacOS publicized a few days before the comic was released, as well as [https://thenextweb.com/apps/2017/01/18/iphone-ipad-apple-text-ios-bug/ past] [http://www.telegraph.co.uk/technology/2018/01/18/apple-text-bomb-can-crash-iphones-single-message/ similar] iOS vulnerabilities.&lt;br /&gt;
;An attacker can use a timing attack to extploit [''sic''] a race condition in {{w|Garbage collection (computer science)|garbage collection}} to extract a limited number of bits from the Wikipedia article on Claude Shannon.&lt;br /&gt;
:The reference to using a Timing Attack to exploit a race condition in garbage collection refers to Meltdown and Spectre CPU flaws that can be exploited in a cloud server like the ones in Wikipedia. {{w|Claude Shannon}} was an early and highly influential information scientist whose work underlies compression, encryption, security, and the theory behind how information is encoded into binary digits. &lt;br /&gt;
:&lt;br /&gt;
:This is not a security problem. However, since Shannon formulated how the amount of unique or actual information some entity contains is proportional to the number of bits required to encode it, retrieving only a few bits casts a dark perspective upon the significance of the Shannon article's content.&lt;br /&gt;
;At the cafe on Third Street, the Post-it note with the WiFi password is visible from the sidewalk.&lt;br /&gt;
:Cafés often offer free access to WiFi as a service to patrons, as a business strategy to encourage said patrons to remain in the building and buy more coffee. Some use a password, so that only patrons can use the WiFi, and may display the password on signage inside. Since anybody could go into the cafe to read the post-it, and then use the network from nearby, the ability to read it from outside is, at most, a trivial problem. For systems that are supposed to be secure, writing passwords in a visible place is a major security flaw. For instance, following the [[wikipedia:2018 Hawaii false missile alert|2018 Hawaii false missile alert]], the agency concerned received criticism for a press photo showing [http://uk.businessinsider.com/hawaii-emergency-agency-password-discovered-in-photo-sparks-security-criticism-2018-1?r=US&amp;amp;IR=T a password written on a sticky note] attached to a monitor.&lt;br /&gt;
;A remote attacker can inject arbitrary text into public-facing pages via the comments box.&lt;br /&gt;
:Describes a common feature on news sites or social media sites like Facebook. The possibility for users to &amp;quot;inject&amp;quot; text into the page is by design. This is a humorous reference to the relatively common security vulnerability &amp;quot;[[Wikipedia:Cross-site_scripting|persistent cross-site scripting]]&amp;quot;, where input provided by a user, such as through a comment section, can result in dangerous content containing arbitrary HTML or JavaScript code being displayed to other users. &lt;br /&gt;
;MySQL server 5.5.45 secretly runs two parallel databases for people who say &amp;quot;S-Q-L&amp;quot; and &amp;quot;sequel.&amp;quot;&lt;br /&gt;
:Some people pronounce &amp;quot;{{w|SQL}}&amp;quot; like &amp;quot;sequel&amp;quot;, after SQL's predecessor &amp;quot;SEQUEL (Structured English Query Language)&amp;quot;. The standard for SQL suggests that it should be pronounced as separate letters; however, the author of SQL pronounces it &amp;quot;sequel&amp;quot;, so the debate is persisting (with even more justification than arguments about how to pronounce &amp;quot;GIF&amp;quot;). MySQL is an open-source relational database management system. The latest generally available version (at the time of writing) is MySQL 5.7.&lt;br /&gt;
;A flaw in some x86 CPUs could allow a root user to de-escalate to normal account privileges.&lt;br /&gt;
:{{w|Privilege escalation}} refers to any illegitimate means by which a system user gains greater access than they are supposed to have, and most hackers will seek to achieve this if they can. The most highly-sought privilege is that of the root user, which allows complete access to an entire system&amp;amp;mdash; a ''superuser''.&lt;br /&gt;
:&lt;br /&gt;
:The irony of this CVE presents the reverse situation: that a flaw inadvertently ''de-escalates'' a root user to a less privileged user, which would cripple the ''superuser'', they would be disallowed access or ability to accomplish their required tasks, or worse, cause such tasks which do not {{w|fail safe}} to have catastrophic side effects.&lt;br /&gt;
;Apple products catch fire when displaying emoji with diacritics.&lt;br /&gt;
:This is a reference to a common problem of modern gadgets catching fire (usually related to flaws in lithium-ion batteries), as well as to Apple products crashing when attempting to display certain character sequences. Diacritics are the accents found on letters in some languages (eg. č, ģ ķ, ļ, ņ, š, ž). These would not normally be found on emojis. 🔥̃ is an example of such an emoji.&lt;br /&gt;
;An oversight in the rules allows a dog to join a basketball team.&lt;br /&gt;
:This probably refers to the movie {{w|Air Bud}}, about a dog playing basketball. This has been a common theme in xkcd comics: see [[115: Meerkat]], [[1439: Rack Unit]], [[1819: Sweet 16]], [[1552: Rulebook]].&lt;br /&gt;
:In 2017, it was discovered that an oversight in the constitution of the state of Kansas may [http://www.kansascity.com/news/politics-government/article175956836.html permit a dog to be governor]. Shortly before this comic published, the Secretary of State's office ruled that [http://dfw.cbslocal.com/2018/02/13/dog-kansas-governor/ it could not].&lt;br /&gt;
;Haskell isn't side-effect-free after all; the effects are all just concentrated in this one computer in Missouri that no one's checked on in a while.&lt;br /&gt;
:{{w|Haskell (programming language)|Haskell}} is a functional programming language. Functional programming is characterized by using functions that don't have side effects because they can not change things accessible in other parts of the program, as in [[1312: Haskell]]. The joke here is discovering that it does indeed have side-effects, manifested via external alteration, not violating the internal alteration paradigm. It may also be a reference to &amp;quot;The Ones Who Walk Away From Omelas,&amp;quot; a short story by Ursula Le Guin in which a utopian city concentrates all its misery into one child who is locked away in a basement.&lt;br /&gt;
;Nobody really knows how hypervisors work.&lt;br /&gt;
:[[wikipedia:Hypervisor|&amp;quot;Hypervisors&amp;quot;]] are a tool for computer virtualization. Virtualization is implemented via various combinations of hardware and/or software, which requires a computer to completely simulate another computer, with its own unique hardware and software, and to varying degrees as to whether or not the virtualization is aware of or can determine whether it is being virtualized. Many IT professionals and businesses rely heavily on various forms of virtualization, but most of the individual employees would be hard-pressed to explain how it works. Programs running on other virtual computers, or on the real computer, may be able to access information on a virtual computer in ways which would not be possible with a single real computer. Consequently, understanding how the hypervisor works is important to assessing the security of a virtual server. Meltdown and Spectre are related to this.&lt;br /&gt;
;Critical&amp;amp;#x3A; Under Linux 3.14.8 on System/390 in a UTC+14 time zone, a local user could potentially use a buffer overflow to change another user's default system clock from 12-hour to 24-hour.&lt;br /&gt;
:This joke is about arcane systems that are running Linux in exceedingly rare situations, meaning that reproducing errors would be incredibly difficult or inconvenient, and would only affect a very tiny user base (if any at all). {{w|IBM System/390 ES/9000 Enterprise Systems Architecture ESA family|System/390}} is an IBM mainframe introduced almost 30 years before this comic, which has a version of Linux. UTC+14 is a time zone used only on some islands in the Pacific Ocean (Primarily [[Wikipedia:Line_Islands|the Line Islands]]) and is also the earliest time zone on earth. Even if all of these absurd conditions were met, the resulting vulnerability would still be relatively benign: simply changing a user's preferred clock display format. Other xkcd comics make references to such obscure computer-time issues relating to time zones and time conversions, and how many programmers find these issues frustrating or even traumatizing. &lt;br /&gt;
;x86 has way too many instructions.&lt;br /&gt;
:The x86 architecture (used in many Intel and AMD processors) is very complicated. Processors typically implement such a complex architecture using programs (microcode) run on a set of hidden, proprietary processors. The details of these hidden machines and errors in the microcode can result in security vulnerabilities, such as Meltdown, where the physical machine does not match the conceptual machine.&lt;br /&gt;
:&lt;br /&gt;
:A more complicated instruction set is more complex to implement.{{Citation needed}} The x86 architecture is considered &amp;quot;CISC&amp;quot; (a &amp;quot;{{w|Complex instruction set computer}}&amp;quot;), having many instructions originally provided to make programming by a human simpler; other examples include the 68000 series used in the first {{w|Apple Macintosh}}. In the 1980s, this design philosophy was countered by the &amp;quot;RISC&amp;quot; (&amp;quot;{{w|Reduced instruction set computer}}&amp;quot;) design movement - based on the observation that computer programs were increasingly generated by compilers (which only used a few instructions) rather than directly by people, and that the chip area dedicated to extra instructions could be better dedicated to, for example, cache. Examples of RISC style designs include {{w|SPARC}}, {{w|MIPS}}, {{w|PowerPC}} (used by Apple in later Macintoshes) and the {{w|ARM architecture|ARM}} chips common in mobile phones. Historically, there was considerable discussion about the merits of each approach. At one time the Mac and Windows PC were on different sides; owners of other competing systems such as the Archimedes and Amiga had similar arguments on usenet in the early 1990s. This &amp;quot;issue&amp;quot; may be posted by someone who still recalls these debates. Technically, the extra instructions do slightly complicate the task of validating correct chip behaviour and complicate the tool chains that manage software, which could be seen as a minor security risk. However, the 64-bit architecture introduced by {{w|AMD}}, and since adopted by {{w|Intel}}, does rationalise things somewhat, and all recent x86 chips break down instructions into RISC-like micro-operations, so the complication from a hardware perspective is localised. Recent security issues, such as the speculative cache load issue in Meltdown and Spectre, depend more on details of implementation, rather than instruction set, and have been exhibited both by x86 (CISC) and ARM (RISC) processors.&lt;br /&gt;
:&lt;br /&gt;
:This explanation has way too many words.&lt;br /&gt;
;NumPy 1.8.0 can factor primes in ''O''(log ''n'') time and must be quietly deprecated before anyone notices.&lt;br /&gt;
:Fantastically, this would be an unimaginable software threat, not to be confused with the even speedier, but future-bound, threat in hardware via {{w|Quantum computing}}. &lt;br /&gt;
:NumPy is the fundamental package for scientific computing with the programming language Python. ''O''(log ''n'') is [[wikipedia:Big_O_notation#Infinite_asymptotics|Big O notation]] meaning that the time it takes for a computer algorithm to run is in the order of log ''n'', for an input of size ''n''. ''O''(log ''n'') is very fast and is more usual for a search algorithm. Prime factorization currently is ''O''(''2''&amp;lt;sup&amp;gt;''n''&amp;lt;/sup&amp;gt;n)). If something can find the prime factors of a number this quickly, especially a [[wikipedia:semiprime|semiprime]] with two large factors, it will enable attacks to break many crypto functions used in internet security. However, prime numbers have only a single factor, and &amp;quot;factoring primes&amp;quot; quickly is a simpler problem, that of [[wikipedia:Primality test|proving that a number is in fact a prime]]. &lt;br /&gt;
;Apple products grant remote access if you send them words that break the &amp;quot;I before E&amp;quot; rule.&lt;br /&gt;
:Another joke on the first CVE and [[wikipedia:I before E except after C|a common English writing rule of thumb]], which fails almost as often as it succeeds. Possibly a jab at Apple's image, portraying their software as unable to handle improper grammar or spelling.&lt;br /&gt;
;Skylake x86 chips can be pried from their sockets using certain flathead screwdrivers.&lt;br /&gt;
:Skylake x86 chips are a line of microprocessors made by Intel. Some processors are soldered directly to a system board or daughter board, while others are attached to boards that plug into the system board by means of a socket (pins or connectors that make physical contact with receptacles or connectors on a system board). Some sockets, especially older ones, require force to insert or remove, and often require the use of a flat blade screwdriver or a specialized tool, but most modern ones use ZIF (Zero Insertion Force) techniques, often involving a lever or similar to tighten or loosen the friction/tightness of the contacts. No screwdriver is needed in this case. However, any processor ''can'' be forcefully removed from its socket with a screwdriver.{{Citation needed}}&lt;br /&gt;
;Apparently Linus Torvalds can be bribed pretty easily.&lt;br /&gt;
:{{w|Linus Torvalds}} is the {{w|benevolent dictator for life}} of the Linux kernel codebase. Normally it is hard to make changes because he has the last word, and because the kernel is replicated in all Linux installations. Linus made the news in January 2018 when, having looked at one of Intel's proposed fixes for the Spectre and Meltdown vulnerabilities, he declared &amp;quot;[https://techcrunch.com/2018/01/22/linus-torvalds-declares-intel-fix-for-meltdown-spectre-complete-and-utter-garbage/ the patches are COMPLETE AND UTTER GARBAGE]&amp;quot;. Presumably, it may be found that he may be successfully bribed to be less blunt and/or less critical of vulnerability fixes that are complete and/or utter garbage. If this were the case, this would be a severe critical vulnerability to all Linux servers and machines.&lt;br /&gt;
;An attacker can execute malicious code on their own machine and no one can stop them.&lt;br /&gt;
:The point of an attack is to make someone else's machine perform actions against the owner's will. Anyone can make their own machine execute any code if they have root access and the necessary tools, but this would usually not be described as an attack, except in the case of a locked-down appliance, such as a video game console, a John Deere tractor, or pay TV decoder.&lt;br /&gt;
;Apple products execute any code printed over a photo of a dog with a saddle and a baby riding it.&lt;br /&gt;
:This could refer to a CVE vulnerability of JPG files where JavaScript embedded within the image file is executed by some application. In this case, though, the code is visible on the image instead of invisibly encoded within the image file. The code is also only executed if the image contains a photo of a baby in a saddle riding a dog. It's unclear whether the photo would be a digital photo, a printed photo (i.e. as taken using a digital camera), or maybe both. &lt;br /&gt;
:Other than by some {{w|metadata}}, either internal to the image file, or embedded along with it, as in a web page, or a PDF or other container file, this &amp;quot;bug&amp;quot; would require the device to {{w|Hard AI|figure out}} specifically what the photo contains image-wise (something that's REALLY HARD for computers to do reliably), but would also require OCR (optical character recognition) code to convert the text superimposed on the photo into executable code. In other words, it's hard to believe in 2018 that such a bug could exist. Maybe in the future when such things are more routine...? As an example, OCR used to be hard to do reliably, but now it's a lot more routine and built into a lot of devices.&lt;br /&gt;
;Under rare circumstances, a flaw in some versions of Windows could allow Flash to be installed.&lt;br /&gt;
:Flash has been an integral browser plugin for decades, but has fallen out of favor in the 2010s, and eventually discontinued because of its notoriously abysmal security record. All security experts advise against installing it. Preventing installation of Flash would make systems more secure, but most versions of Windows do not prevent Flash installation. The joke here relates to the difficulty of keeping Flash up to date, or even installed properly to begin with. A common user experience, which is the subject of numerous jokes and memes, is the constant nagging notification to install or update Flash in order for web pages to display properly. Many IT professionals will bemoan the trouble they have experienced in the workplace due to these notifications and problems related to them.&lt;br /&gt;
;Turns out the cloud is just other people's computers.&lt;br /&gt;
:This refers to a meme that demands that &amp;quot;cloud&amp;quot; be replaced with &amp;quot;other people's computers&amp;quot; in all marketing presentation to CEOs and non-computer literate persons evaluating the security impact of using cloud services. Part of the humor here is that &amp;quot;the cloud&amp;quot; is, in actuality, simply a term for hosted services, or in other words computers being run by other people (typically businesses that specialize in this type of &amp;quot;{{w|Platform as a Service}}&amp;quot; or &amp;quot;PaaS&amp;quot; service model). Referring to &amp;quot;the cloud&amp;quot; as &amp;quot;other people's computers&amp;quot; is, at its core, entirely accurate, though it takes away the business jargon and simplifies the situation in such a way that it might cast doubt on the security, reliability, and general effectiveness of using &amp;quot;cloud&amp;quot; solutions.&lt;br /&gt;
;A flaw in Mitre's CVE database allows arbitrary code insertion.[[779|[~~CLICK HERE FOR CHEAP VIAGRA~~]]]&lt;br /&gt;
:Mitre's CVE database is where all {{w|Common Vulnerabilities and Exposures|CVEs}} are stored. This log message forms the punchline of the comic, as it implies that all of the exaggerated error messages above might have been inserted by hackers exploiting the vulnerability.

| number    = 2116&lt;br /&gt;
| date      = February 25, 2019&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Cueball's friend seems to have sent him a rather unusual datafile passed off as a new &amp;quot;normal&amp;quot; standard.&lt;br /&gt;
&lt;br /&gt;
People who work with data, and need data sent to them electronically, typically need it sent in a way that they can easily use it -- either in a text format that can be copy-pasted, or as a spreadsheet or CSV file that can be imported into a spreadsheet program, or such.  Information sent in this fashion -- a photograph of a spreadsheet embedded into a word processing file -- is absolutely useless for any purpose beyond being looked at.  The recipient has no choice but to retype the entire data set, or attempt to use optical character recognition (OCR), and hope that no mistakes are made in the process.&lt;br /&gt;
&lt;br /&gt;
Any functional relationships between data (such as formulas used to compute data values) have been lost.  Further, the size of the data is bloated by being converted first from numbers and formulas into text, then text into graphics, and then from graphics to embedded graphics in a word processing document.  This adds nothing to the content, and only adds steps to the process of retrieving the data.&lt;br /&gt;
&lt;br /&gt;
The comic image links to a [https://twitter.com/openelex/status/853977391747801088 tweet by OpenElections] that displays an Excel file produced by the City of Detroit that contains a lookup table for the city's absentee precincts in 2016. The data had been input as clip art (images) of the values, instead of being entered in the spreadsheet cells.&lt;br /&gt;
&lt;br /&gt;
This comic is reminiscent of the comic [[763:_Workaround|Workaround]], which also describes convoluted formats.&lt;br /&gt;
&lt;br /&gt;
The title text suggests that eventually compression (or at least compression with data/quality loss) will be unnecessary as technology improves in the future. SVG ({{w|Scalable Vector Graphics}}) is a vector graphic format that is fundamentally a lossless format, representing images using geometric figures. {{w|JPEG}} is a lossy format, representing images as an array of rectangles approximating the original image.  Randall suggests that some people in the future may choose to include JPEG artifacts to SVG vector graphics for its &amp;quot;aesthetics&amp;quot;, perhaps as a throwback to when lower quality JPEG images were commonplace, or as a form of {{w|glitch art}}. It is possible that some in the future will view JPEG artifacts as giving their images a quaint/retro feel, much the way that some people today use sepia-tone filters on their images.&lt;br /&gt;

Even though space is cold, it conducts so poorly that spacecraft would probably have more problems getting rid of heat than keeping heat, considering how isolated they are. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 16:43, 22 February 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
:It actually has little to do with conduction; the heat radiates pretty effectively, especially as it gets &amp;quot;hotter&amp;quot; vs the surrounding radiation. [[Special:Contributions/172.69.69.124|172.69.69.124]] 17:35, 22 February 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
::You're right, spacecraft are cooled by radiation. Yet it is far less effective than conductive/convective cooling by blowing the surrounding medium (water, air, whatever) over the hot parts. It's so much easier to cool things down here on Earth! Cooling problems is one of the reasons why nuclear reactors are not very popular in space, they need massive cooling systems.&lt;br /&gt;
&lt;br /&gt;

I put in how the title text makes a probable reference to game development. [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 17:41, 22 February 2019 (UTC)&lt;br /&gt;
:It could, with equal probability, be a reference to parallel universes. There's nothing anywhere that says anything about game development.... [[Special:Contributions/162.158.214.10|162.158.214.10]] 18:29, 22 February 2019 (UTC)&lt;br /&gt;
:”Cool Mechanic” “Unbalanced” and “Join the team” seemed like hints [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 18:33, 22 February 2019 (UTC)&lt;br /&gt;
::It seemed obvious to me it was a reference to episodic story development, as it looks like that happens with shows and comics all the time.  Don't understand how it makes sense for parallel universes (except that this kind of happened with star trek and the introduction of the parallel reality) but recommend updating the article to include all interpretations. [[Special:Contributions/172.68.47.240|172.68.47.240]] 21:20, 22 February 2019 (UTC)&lt;br /&gt;
:::I thought it was more in the line of someone joining a D&amp;amp;D game, doing something crazy with their character then leaving, and the remaining players all have to keep up the story.&lt;br /&gt;
&lt;br /&gt;
This seems to be in the same vein as two other recent comics, Internet Archive and ArkXiv. Perhaps real things that seem unrealistic is a new topic of Randalls? [[Special:Contributions/172.69.247.4|172.69.247.4]] 17:53, 22 February 2019 (UTC)&lt;br /&gt;

&lt;br /&gt;
Re: &amp;quot;Note that the radioactive material obviously doesn't produce this energy forever, although it can produce it so long the device will break before it gets out of energy.&amp;quot;  The main problem with Voyager I and Voyager II is not that the devices on board have been broken, exhausted a finite reserve or otherwise failed, but that the power supply can not keep most of the machine powered anymore.  In fact, if there was enough electrical power, most of the cameras and other sensors would still work; they might see much that far from the sun and other bodies, but they would work.  The plutonium power source undergoes exponential decay, producing proportionally less power each year and each year, the NASA scientists have to decide which devices on the spacecraft need to power-down, never to turn on again, or maybe a device is so important, but needs so much power that they will turn it on for less and less time, sort of like rotating brown-outs.  I think the Pioneer probes are in the same boat.  [[User:Nutster|Nutster]] ([[User talk:Nutster|talk]]) 04:13, 23 February 2019 (UTC)&lt;br /&gt;
:Also because of the many restrictions on use of highly radioactive material, plus the basic weight factor, you would only use just the amount of plutonium required to power the craft fully over it's expected lifetime. After that lifetime you no longer have full power due to decay.[[Special:Contributions/172.68.146.20|172.68.146.20]] 05:47, 25 February 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Could someone perhaps expand on the term &amp;quot;implementing a mechanic&amp;quot;? In New Zealand English at least, a mechanic is a person who works with machines. I thought this was maybe a synonym for &amp;quot;implementing a mechanism&amp;quot;, but it seems to have a specific meaning in the team episode writing sense discussed here.

This comic pokes fun at the properties of plutonium, claiming that it is so unrealistically powerful that it may as well be random sci-fi jargon. Indeed, the ability for a metal to radiate free energy sounds impossible. This is reflected by Megan and Hairy treating Cueball's idea as a practical joke.&lt;br /&gt;
&lt;br /&gt;
There are devices that need substantial electrical power over long time &amp;amp;ndash; in the order of decades &amp;amp;ndash; but local sources of energy are insufficient or unavailable, yet constructing a power line or resupplying them with some power source (like fuel, fresh chemical batteries etc.) is either impossible or overly costly. Such devices include maritime beacons and buoys, automatic weather and science stations located in remote areas, and &amp;amp;ndash; most importantly &amp;amp;ndash; deep space probes and some planetary probes or science packs. Probes sent beyond Jupiter cannot effectively rely on photovoltaic panels for energy, because the large distance to the Sun means that the amount of solar radiation per unit of area is very low, requiring impractically large (and thus heavy) panels to provide enough energy. Carrying a lot of fuel also adds mass to the probe.&lt;br /&gt;
&lt;br /&gt;
Instead, such devices usually use {{W|radioisotope thermoelectric generator}}s (RTGs). In an RTG the natural radioactive decay of some unstable isotope (such as Plutonium-238 or Strontium-90) produces a lot of heat, which is then used to generate energy using {{W|thermocouple}}s, which generate electricity directly from heat by employing the {{W|thermoelectric effect}}. The key element of an RTG, a pellet of radioactive material such as plutonium dioxide, could be facetiously described as a &amp;quot;power orb&amp;quot; &amp;amp;ndash; a lump of a substance that gives out heat apparently out of nothing.&lt;br /&gt;
&lt;br /&gt;
The title text references video game development, and how after joining a team and implementing a mechanic, a dev can leave, and give others working on it little or no knowledge of how to fix a specific design.&lt;br /&gt;

{{incomplete|Made By a GUY WITH ONIONS IN HIS ROOM, HE ISN'T CYRING... . Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic is a paean to the {{w|Opportunity (rover)|Opportunity rover}}, and its nearly 15 year mission in which it sent back publicly available photos and research from Mars to Earth. The evening prior to this comic uploading (Feb 12, 2019), Nasa's JPL sent their [https://arstechnica.com/science/2019/02/opportunity-did-not-answer-nasas-final-call-and-its-now-gone-to-us/ final data request] to the rover, in hopes that it would respond. When it did not, the rover was declared to be officially lost.&lt;br /&gt;
&lt;br /&gt;
The comic starts with White Hat, looking at some people taking photographs and lamenting the fact that they're taking pictures all the time, saying &amp;quot;Kids these days...&amp;quot;, a common complaint of younger people by their elders. This is actually a straw-person argument, as White Hat is lamenting that the younger generation look at the world through their camera phones and thus don't experience it directly, and believe that they lose some of the joy of the event in the process - [[1314: Photos|an opinion he has expressed previously]].  &lt;br /&gt;
&lt;br /&gt;
To this [[Randall]] appears to counter that sharing and showing to others is an exciting part of the joy, an opinion which he has also expressed in [[1314: Photos|comic 1314]]. He then proceeds to say that the Oppurtunity of exploring a completely new world is an exciting part of the exploration, and expresses joy in the fact that MER-B Opportunity was able to share its experiences in its 15-year, 45-kilometer journey on Mars with the entirety of humanity.&lt;br /&gt;
&lt;br /&gt;
The comic ends by thanking Rover (and NASA) for allowing the general public the incredible experiences it had on Mars in its 15 Earth-year lifetime, to receive the pictures and data, while traversing along hostile terrain for us. The last panel shows some &amp;quot;followers&amp;quot; which represents everyone on Earth listening to the words from Rover as it transmits the incredible experiences it had on Mars in its 15 Earth-year lifetime. Note, perhaps the reference to &amp;quot;dust devil&amp;quot; suggests these may have been the last such descriptions as that may refer to the deadly global dust storm that likely killed the Rover and ended the mission. The dust-devils were also likely responsible for the amazing extended missions for both rovers as they tended to blow the accumulated dust off the solar panels.&lt;br /&gt;
&lt;br /&gt;
The title text shows gratitude for the rover, which brought everyone on Earth, including Randall along in its journey by sending images of the journey to Earth.  Also, Randall used to work for NASA, so as much joy as it brought the world at large, it probably felt just a little more personal for him.&lt;br /&gt;
&lt;br /&gt;
The Opportunity rover also appeared in [[1504: Opportunity]], while its twin rover Spirit also had a dedicated comic in [[695: Spirit]]&lt;br /&gt;

| titletext = To avoid errors like this, we render all text and pipe it through OCR before processing, fixing a handful of irregular bugs by burying them beneath a smooth, uniform layer of bugs.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
In some word processor programs, when highlighting text, whether by manually clicking and dragging or by double-clicking on a passage, it is easy to mistakenly highlight an unnecessary portion which has no visible effects when italicized or boldfaced. Since in most fonts the word space looks identical between the bold, the italicized, and the regular, this has no effect on how the end user will read the document, but could theoretically cause a problem on later occasions, particularly if the text cursor does not reflect formatting when hovering over formatted characters. [[Randall]] worries about this.&lt;br /&gt;
&lt;br /&gt;
In the pictured case, he does not appear to have selected the word by double-clicking, since the cursor is depicted past the end of the word instead of on top of it. It appears instead that he has clicked and dragged the mouse cursor to select it, a method which also makes it easy to accidentally select a trailing space. The word space is a relatively thin character, which makes it hard to avoid and to notice, and most people don’t worry about whether they selected it. Therefore, selecting a trailing space is a common behavior, regardless of the method used.&lt;br /&gt;
&lt;br /&gt;
If later the same word is highlighted to have the bold removed, but this time without including the space, the space would retain its bold formatting. Since it is an invisible character, there is no easy way to tell it is still bold—even if it is slightly longer in the bold font, this may be hard to notice. This is the situation the comic is highlighting—[[559: No Pun Intended|no pun intended]].&lt;br /&gt;
&lt;br /&gt;
Occasions where a hidden bold space may be a problem include:&lt;br /&gt;
*Exporting to plain text files.  If for example a {{w|markdown}} style is used, there will be characters in the output that do not make sense.&lt;br /&gt;
*Scraping, data mining, and linguistics processing by computer algorithms.  Often (although not always) these algorithms are written based on samples of training or testing text that may not have spurious formatting present, and may misprocess something when encountering the spurious formatting.&lt;br /&gt;
*Wikis. In the first paragraph of this article, every space is a hidden bold space. From the editing view, all the spaces look &amp;lt;code&amp;gt;&amp;lt;nowiki&amp;gt;like''' '''this&amp;lt;/nowiki&amp;gt;&amp;lt;/code&amp;gt;. This will annoy all future editors of this article, due to the hidden apostrophes which are formatting the spaces. They may also accidentally introduce bold words.&lt;br /&gt;
**By default, MediaWiki attempts to prevent this by not including the trailing spaces in the bold formatting when you click the “bold” button, so someone has to manually type the formatting apostrophes to do this.&lt;br /&gt;
*Editing that adds some text at the location of the space will make this text bold.&lt;br /&gt;
*A situation where formatted text is not allowed, and is rejected, but the user failed to strip formatting from the spaces, and this is noticed.&lt;br /&gt;
*If a font has the word space look different between the bold and the regular, perhaps to make it so bold words are spaced closer to each other, the spacing will look inconsistent if there is a hidden bold space.&lt;br /&gt;
*Unnecessary extra formatting will usually unnecessarily increase file size, which may put the document above some maximum file size threshold.&lt;br /&gt;
*It can be later revealed that Randall considered to format parts of the text in bold. As the title text tells it is really important to Randall to control all information he publishes. Real-world examples are governments changing the impact of reports for political reasons. Attempted tampering of this kind can be revealed by bold spaces. Another example would be a casual and short one-sentence reply e.g. to a romantic interest, which one takes one hour to formulate to sound as natural as possible.&lt;br /&gt;
&lt;br /&gt;
Randall’s background in {{w|computer programming}} could be what makes him more attentive to these types of technical problems, and therefore the reason for his worries.&lt;br /&gt;
&lt;br /&gt;
Popular modern word processing programs have features which may make it easier to notice improperly formatted invisible characters. In the tutorials linked here, one may learn how to view invisible characters in [https://support.office.com/en-us/article/show-or-hide-formatting-marks-c2d8a607-5646-4165-8b08-bd68f9d172a0 Microsoft Word], [https://support.apple.com/kb/PH23650?locale=en_US&amp;amp;viewlocale=en_US Pages] and [https://help.libreoffice.org/Writer/Nonprinting_Characters LibreOffice Writer], however even with this on it would be difficult to spot a bolded space (which looks like a bolded dot &amp;amp;ndash; now visible but so small it's still hard to tell if it's bold or not). In the older word processor {{w|WordPerfect}}, one could do this with the “Reveal Codes” feature, which showed you character codes, separate from the characters themselves, around the characters.  For example, a bolded space would look something like &amp;quot;&amp;lt;span style=&amp;quot;background:#34F5FF&amp;quot;&amp;gt;[BOLD&amp;amp;#8827;&amp;lt;/span&amp;gt;&amp;amp;ensp;&amp;lt;span style=&amp;quot;background:#34F5FF&amp;quot;&amp;gt;&amp;amp;#8826;BOLD]&amp;lt;/span&amp;gt;&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
In the title text, Randall says that he “fixes” this by running the text through {{w|Optical character recognition|OCR}}, which turns physical copies or images into text. This would usually ruin even more formatting, and add inaccuracies to the text. This way, no one can tell which bugs were introduced by him and which ones by the OCR, which he facetiously suggests is better somehow.&lt;br /&gt;

| titletext = And let's be honest, it's more like two and a half stars. Proxima is barely a star and barely bound to the system.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a SOLAR SAIL. It would be good to enumerate similar projects. Do NOT delete this tag too soon.}}&lt;br /&gt;
{{w|Alpha Centauri}} is the closest star system to our solar system, being 4.37 {{w|light-year}}s away. As such, there are numerous ongoing plans and projects to journey to, and explore the star system, especially since the exoplanet {{w|Proxima Centauri b}} was found in 2016 to possibly have liquid water oceans and a very thin atmosphere. Ponytail announces such a project using a {{w|Voyager program|Voyager}}-like probe.&lt;br /&gt;
&lt;br /&gt;
However, an offscreen person is against the idea of sending a probe to that particular part of the galaxy, as they think that &amp;quot;Alpha Centauri sucks&amp;quot;. The person says that they looked &amp;quot;online&amp;quot; and that the system &amp;quot;only has three stars&amp;quot;. This is a pun playing on the stars used in online reviews and stars as celestial objects.&lt;br /&gt;
&lt;br /&gt;
===Star Rating Systems===&lt;br /&gt;
Online rating systems, such as {{w|Yelp}}, often use {{w|Star (classification)|star rating system}}s, with more stars indicating higher quality, up to an arbitrary maximum, such as five stars to indicate the best rating. Due to [https://www.explainxkcd.com/wiki/index.php/937:_TornadoGuard the nature of 5 star rating systems], [https://www.explainxkcd.com/wiki/index.php/1098:_Star_Ratings anything scoring less than 4 out of 5 in a 5 star rating system is crap]; and in a 10-star rating system, scoring a mere 3 stars out of a possible 10 stars would be ''exceedingly'' low quality. The Alpha Centauri star system has 3 ''physical'' {{w|star}}s: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. The offscreen person has misconstrued this fact of the system as some kind of review.&lt;br /&gt;
&lt;br /&gt;
A previous comic, [[1098: Star Ratings]], points out that star ratings below 4 out of 5 tend to be seen as &amp;quot;crap&amp;quot;. &lt;br /&gt;
&lt;br /&gt;
The title text furthers the pun. Some online star rating systems also allow partial stars, such as a half-star, to allow more precision in rating (e.g. rating 2.5 stars instead of being forced to chose 3 stars or 2 stars), or display an average collective rating as partial stars (e.g. showing 2.5 stars when five people have rated 3 stars and five people have rated 2 stars). Alpha Centauri's &amp;quot;half star&amp;quot; refers to Proxima Centauri, a {{w|red dwarf}}, which is a type of low-mass star. According to the offscreen person, this barely qualifies it to be a star. Furthermore, Proxima Centauri is nearly 13,000 AU (0.21 light years) away from the other 2 stars in the system, so it was long unknown whether Proxima Centauri was gravitationally bound to the Alpha Centauri star system.&lt;br /&gt;
&lt;br /&gt;
===Calculations===&lt;br /&gt;
All numbers are rounded after subsequent calculations.&lt;br /&gt;
&lt;br /&gt;
According to [https://www.space.com/41447-parker-solar-probe-fastest-spacecraft-ever.html space.com] the fastest spacecraft ever will be the Parker Solar Probe which will reach 430,000 mph (692,000 km/h) as it reaches its closest point orbiting the sun. This is just over half of 1% of the needed speed of the Alpha Centauri vehicle proposed in the comic. The Voyager 1 spacecraft, launched in 1977, is currently traveling at about 38,000 mph (61,000 km/h).&lt;br /&gt;
&lt;br /&gt;
Distance to Alpha Centauri system = 4.367ly&lt;br /&gt;
&lt;br /&gt;
4.367 light years / 35 years = 0.12477ly per year&lt;br /&gt;
&lt;br /&gt;
0.12477 light years/year * 5.879e+12 miles/light year = 733,484,000,000 miles/year&lt;br /&gt;
&lt;br /&gt;
733,484,000,000 miles/year / 365 days/year / 24 hours/day = 83,000,000 Miles/hour / 1.60934 miles/kilometer = 134,000,000 Kilometers/hour&lt;br /&gt;
&lt;br /&gt;
The above math assumes a constant speed, and requires a speed of ~0.124855c.  Assuming a constant acceleration from rest (non-relativistic math follows):&lt;br /&gt;
&lt;br /&gt;
35*365.25*24*60*60 = 1.10e+9 seconds in 35 years&lt;br /&gt;
&lt;br /&gt;
4.367 * 5.879e+12 = 2.57e+13miles, 4.13e+13 km, 4.13e+16 m.&lt;br /&gt;
&lt;br /&gt;
x = 1/2*a*t&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;&lt;br /&gt;
&lt;br /&gt;
a = 2*x*t &amp;lt;sup&amp;gt;-2&amp;lt;/sup&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Assuming constant acceleration to the halfway point and constant deceleration to the destination, (otherwise you streak through the system, barely observing anything):&lt;br /&gt;
&lt;br /&gt;
t&amp;lt;sub&amp;gt;trip&amp;lt;/sub&amp;gt; = 2*t&amp;lt;sub&amp;gt;halfway&amp;lt;/sub&amp;gt;&lt;br /&gt;
&lt;br /&gt;
a = 2*2.06e+16*(5.50e+8) &amp;lt;sup&amp;gt;-2&amp;lt;/sup&amp;gt; = 0.136 m/s&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;, roughly 1/80 gravity.&lt;br /&gt;
&lt;br /&gt;
v&amp;lt;sub&amp;gt;halfway&amp;lt;/sub&amp;gt; = a*t&amp;lt;sub&amp;gt;halfway&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Top Speed: 75,000,000 m/s ~ 1/4*c. &lt;br /&gt;
&lt;br /&gt;
Assuming E = F*d, 0.136*1*4.13e+16 = 5.37e15 Joules will be required for each kilogram carried to Alpha Centauri in 35 years.  &lt;br /&gt;
&lt;br /&gt;
This would require an unimaginable amount of mass for a conventional chemical rocket, and is a completely impractical power requirement for any sort of passive solar sail concept.&lt;br /&gt;
 &lt;br /&gt;
Further, the top speed is fast enough to require a recalculation using relativistic physics to model the problem.  This means that the energy budget will need to increase, as the relativistic mass of the probe will increase, requiring more force (and thus more energy) to accelerate and decelerate near its top speed than this calculation returns.&lt;br /&gt;
&lt;br /&gt;
[https://en.wikipedia.org/wiki/Breakthrough_Starshot Active], laser based propulsion methods require currently non-existent and purely specualtive laser and materials technologies, as well as a powerplant equivalent to 12,500 of the [https://www.power-technology.com/features/feature-largest-nuclear-power-plants-world/ World's Largest Nuclear Plant] to transport sub-gram masses on this timescale.  This also assumes that any probes can be steered accurately enough across interstellar distances to come close enough to image with any resolution the bodies they will be passing at a non-trivial fraction of c. &lt;br /&gt;
&lt;br /&gt;
Short of FTL travel or near-perfect mass-energy conversion technology, transporting more than a fraction of a gram of material to Alpha Centauri in a human lifetime will be unachievable.  Short of an enormous breakthrough in power generation, transporting even a fraction of a gram is impossible.&lt;br /&gt;
&lt;br /&gt;
Nonetheless, [http://breakthroughinitiatives.org/challenges/3 Breakthrough Starshot] is attempting to send many gram-sized probes to Alpha Centauri within the century.  Following current technological trends, they expect the efficiency of laser-based propulsion to increase by launch time, allowing launches driven by an unreasonably-large-but-achievable amount of power.  The top speed needed is halved by refraining from slowing at all at the destination: the probes will aim a distance away from the target, so that it traverses by slowly enough for a camera to rotate and track it, even at near-light speeds.  To account for error and space dust, the plan is to launch many tiny probes simultaneously.  They may only be able to accomplish their goal if they can get enough funding to actually affect the global economy enough to make the technologies they require more efficient to produce.  Launches would additionally burn incredible quantities of natural gas.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 2099&lt;br /&gt;
| date      = January 16, 2019&lt;br /&gt;
| title     = Missal of Silos&lt;br /&gt;

| titletext = Welcome to Wyoming, motto &amp;quot;We'd like to clarify that Cheyenne Mountain is in Colorado.&amp;quot;&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
This comic plays on the similarity in name between missile silos, places where long range weapons are deployed, and the missal of Silos, an old document residing in Spain.&lt;br /&gt;
&lt;br /&gt;
In Christianity, a {{w|missal}} is a priest's book of instructions, texts and music for the proper celebration of {{w|Mass (liturgy)|Mass}}. The Missal of Silos is an 11th-century missal from the {{w|Abbey of Santo Domingo de Silos}} in northern {{w|Spain}}; it is famous for being the oldest known {{w|paper}} document in Europe, written at a time when the usual writing material was {{w|parchment}}.&lt;br /&gt;
&lt;br /&gt;
{{w|Missile silos}} are often thought to be the first targeting priority in event of a nuclear strike, in hopes of preventing retaliation.  If one was searching for potential nuclear missile targets, the {{w|Missal of Silos}} would most likely be returned as a result of a fuzzy search for &amp;quot;missile silos&amp;quot;, and could be made a target.&lt;br /&gt;
&lt;br /&gt;
{{w|Approximate string matching|Fuzzy, or approximate, string matching}} is a technique used for searching text for sequences of characters similar to a given sequence.  Normal string matching would only find results that matched the search exactly (searching for &amp;quot;''missile''&amp;quot; would find only occurrences of &amp;quot;''missile''&amp;quot;).  Fuzzy string matching instead finds results that are &amp;quot;close enough&amp;quot; by some metric (searching for &amp;quot;''missile''&amp;quot; would find &amp;quot;''missile''&amp;quot; but also close variants like &amp;quot;''missal''&amp;quot; or &amp;quot;''missel''&amp;quot;).  Fuzzy string matching is often used in search engines, as typos, misspellings, and inexact searches are common.&lt;br /&gt;
&lt;br /&gt;
{{w|Cheyenne Mountain}} is a mountain in {{w|Colorado}}, which houses an underground military compound (aptly named the {{w|Cheyenne Mountain Complex}}) designed to withstand a nuclear strike and host to the {{w|North American Aerospace Defense Command}}. {{w|Cheyenne, Wyoming}}, on the other hand, is the capital of {{w|Wyoming}}. The residents of Cheyenne, Wyoming would prefer their town not to be the target of a nuclear attack because of confusion with Cheyenne Mountain. However, Cheyenne, Wyoming is likely a listed target because of the nearby {{w|90th Operations Group}} at {{w|Francis E. Warren Air Force Base}} operating Minuteman III ICBMs from missile silos.&lt;br /&gt;
&lt;br /&gt;
There have been several comics with nuclear weapons as a part of the plot. See for instance [[1655: Doomsday Clock]], where several other comics are mentioned in the explanation.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[A passage from the Wikipedia page for Missal of Silos is shown, with underlined heading and with links in the text in blue font. The last line is partly cut off by the comics panel, but can be read.]&lt;br /&gt;
:&amp;lt;big&amp;gt;'''Missal of Silos'''&amp;lt;/big&amp;gt;&lt;br /&gt;
:&amp;lt;div style=&amp;quot;border-bottom: 1px solid #bbbbbb&amp;quot;&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
:&amp;lt;small&amp;gt;From Wikipedia, the free encyclopedia&amp;lt;/small&amp;gt;&lt;br /&gt;
:The {{w|Missal}} of Silos is the oldest known {{w|paper}} document created in the Christian West; it is 11th century in date.&amp;lt;sup&amp;gt;&amp;lt;span style=&amp;quot;color: #0645AD&amp;quot;&amp;gt;[1]&amp;lt;/span&amp;gt;&amp;lt;/sup&amp;gt;&lt;br /&gt;
:The missal is held in the library of the {{w|Monastery of Santo Domingo de Silos}} near {{w|Burgos, Spain}}. It is one of a number of liturgical manuscripts...&lt;br /&gt;
&lt;br /&gt;
:[Caption below the panel:]&lt;br /&gt;
:Spain would like to remind everyone not to use fuzzy string matching in their nuclear strike target lists.&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*The transcript of the Wikipedia article shown on the comic is using parts of the version as after a [https://en.wikipedia.org/w/index.php?title=Missal_of_Silos&amp;amp;oldid=615075917 revision made on 30th June 2014]. On the day of the publishing of this comic the Wikipedia article changed drastically.&lt;br /&gt;
**This is because a spurt of editing took place on Wikipedia on the day of the comic, since xkcd and Wikipedia editing have similar target demographics.&lt;br /&gt;
**This &amp;quot;xkcd-Wikipedia effect&amp;quot; has happened before. &lt;br /&gt;
***One example of this revolved around [[878: Model Rail]], in which the alt-text mentioned that the debate over the title of the HO/H0 system was disturbingly long, and &amp;quot;coincidentally&amp;quot;, the talk page debate got a little longer on that very day.&lt;br /&gt;
***And most famously, the comic [[1485: Friendship]], caused at least four Wikipedia pages to be vandalized, so these pages had to be semi protected.&lt;br /&gt;
***Of course, the canonical example of an &amp;quot;xkcd-Wikipedia effect&amp;quot; is [[739: Malamanteau]]. [https://xkcd.com/739/] [https://en.wikipedia.org/wiki/Talk:Malamanteau]&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 2102&lt;br /&gt;
| date      = January 23, 2019&lt;br /&gt;
| title     = Internet Archive&lt;br /&gt;
| image     = internet_archive.png&lt;br /&gt;
| titletext = The fact that things like the npm left-pad incident are so rare is oddly reassuring.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a BOT which someone happens to maintain for some reason but which could disappear at any time. Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
The {{w|Internet Archive}} is a project that is invaluable for internet research. It is a public archive of information, including public domain books and music. It also runs the {{w|Wayback Machine}}, an archive of backups of web pages all over the Web at various times that can be used to see past versions of a page, even if that site has since shut down. The Internet Archive accepts submissions of any type of information, including new backups of web pages and newly-made public domain content.&lt;br /&gt;
&lt;br /&gt;
Ponytail and Cueball first remark upon how weird the concept of the Internet Archive is, commenting that it would seem like an implausible concept if not for the fact that it already existed.&lt;br /&gt;
&lt;br /&gt;
This revisits a point that Randall made in [[2085: arXiv]]: in the title text for that comic, he wrote,&lt;br /&gt;
&lt;br /&gt;
:''Both arXiv and archive.org are invaluable projects which, if they didn't exist, we would dismiss as obviously ridiculous and unworkable.''&lt;br /&gt;
&lt;br /&gt;
Our culture has an overarching theme of equating profit with success, so when efforts succeed due to inherent public benefit, this can often yield surprise.&lt;br /&gt;
&lt;br /&gt;
They then become more philosophical, and wonder about invaluable systems that are maintained by a just a few individuals, meaning that they could disappear if any of those people stopped doing what they were doing. They relate this to the function of the {{w|human body}}, which does contain many {{w|List of systems of the human body|systems}} whose function and inner workings are unknown to the average person.&lt;br /&gt;
&lt;br /&gt;
Again, as in [[2085: arXiv]], the two try not to &amp;quot;jinx things&amp;quot; by drawing attention to the improbability of this system working perfectly. In arXiv, when Megan exclaims that being able to post research papers as free PDFs on arXiv &amp;quot;makes no sense at all&amp;quot;, Ponytail responds, ''&amp;quot;Shhh, you'll jinx it!&amp;quot;'' Here, Cueball tells Ponytail, &amp;quot;Probably best not to think about it.&amp;quot;  This is ironic as the inclusion of this information in a popular comic like XKCD is drawing attention to it.&lt;br /&gt;
&lt;br /&gt;
As an example of &amp;quot;invaluable systems maintained by just a few individuals&amp;quot;, the title text refers to the &amp;quot;[https://blog.npmjs.org/post/141577284765/kik-left-pad-and-npm npm left-pad incident]&amp;quot;, a 2016 incident where a package for the {{w|npm (software)|npm}} package manager was removed from the software library by its author. As this particular package was used by many projects, both directly and indirectly, this caused a severe disruption in the software world. Randall is relieved that cases like this do not occur more frequently.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[Ponytail and Cueball are walking to the right.]&lt;br /&gt;
:Ponytail: The Internet Archive is so weird. If it didn't exist, it would sound totally implausible.&lt;br /&gt;
:Cueball: ''Seriously.''&lt;br /&gt;
&lt;br /&gt;
:[Ponytail and Cueball continue walking to the right.]&lt;br /&gt;
:Cueball: Do you ever worry about how reliant we are on systems that someone happens to maintain for some reason but which could disappear at any time?&lt;br /&gt;
&lt;br /&gt;
:[Ponytail and Cueball are seen in silhouette from a distance.]&lt;br /&gt;
:Ponytail: Yeah - the same thing freaks me out about having a body.&lt;br /&gt;
:Cueball: I know, right?? I don't even know what half these parts ''do''!&lt;br /&gt;
:Ponytail: And yet if they stop, we die!&lt;br /&gt;
:Cueball: Probably best not to think about it.&lt;br /&gt;

&lt;br /&gt;
Recently, USA politics has caused polarization of the public.&amp;lt;ref&amp;gt;[https://news.gallup.com/opinion/polling-matters/215210/partisan-differences-growing-number-issues.aspx Partisan Differences Growing on a Number of Issues]&amp;lt;/ref&amp;gt; It is said to be &amp;quot;split&amp;quot; in two camps (liberal and conservative). Here [[Black Hat]] is trying to get elected by promising he will actually split America in two. His presentation suggest he would accomplish this by using a giant crowbar, thus completing the {{w|Midcontinent Rift System|Midcontinent Rift}}, which is a large crack that started to form about 1.1 billion years ago, but failed to completely sever the continent.&lt;br /&gt;
&lt;br /&gt;
It is unclear why would anyone vote for such a thing, but people directly affected (the Midwest) are likely to vote against [[Black Hat]]. While Black Hat and his campaign advisor [[Ponytail]] speak of weakness in the Midwest, they are talking about two different things: Black Hat refers to the physical weakness of the North American Plate in the Midwest due to the geological rift which he thinks could be exploited by a large enough crowbar, while Ponytail is referring to a political weakness for Black Hat's campaign in the Midwest due to the likely-unpopular proposal (different regions of the US have different voters and populations who have different priorities and stances, so candidates and their campaigns' platforms will likely be more popular in some regions and less popular in others).  In this case a successful or attempted completion of the rift would likely result in the destruction of millions of houses, buildings, and other man-made structures, not to mention the deaths of many humans (if proper evacuation were not fully implemented and enforced) as well as millions of animals that could not be evacuated.  The proposal would also cause huge economic impacts; the Midwest produces a significant proportion of America's food supplies and hosts important economic centers, such as Chicago and Cleveland.  So the popularity among those directly or even indirectly affected is likely quite low.&lt;br /&gt;

:::Enough nuclear weapons will eventually crack it, or at least that's the idea.

Wouldn't it make more sense to create a seperate page to collect all the &amp;quot;xkcd-Wikipedia effect&amp;quot; cases? I'm kinda surprised there isn't one already.

The format of this comic is highly similar to the recent comic [[2042: Rolle's Theorem]], with a title and ''From Wikipedia, the free encyclopedia'' header, and the first few paragraphs in the article.&lt;br /&gt;

GPS relies on satellites not the magnetic pole, so it wouldn't be affected.&lt;br /&gt;
&lt;br /&gt;
So, GPS ''receivers'' don't need magnetic poles... but what about the GPS ''satellites''?  GPS works being them transmitting their exact location, so they need so way of knowing what that is.   [[User:JamesCurran|JamesCurran]] ([[User talk:JamesCurran|talk]]) 22:58, 14 January 2019 (UTC)&lt;br /&gt;

I was wondering about that. Just added {{Citation needed}} to that and a couple of other alleged facts that should really be cited if true, and removed if not. [[Special:Contributions/108.162.216.208|108.162.216.208]] 20:35, 14 January 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
It was speculated that reversals were linked to mass extinctions.  This would make the alt-text appear to be a bit blase - but &amp;quot; Statistical analysis shows no evidence for a correlation between reversals and extinctions.&amp;quot;  so it seems we will probably be OK.&lt;br /&gt;
It does seem odd that GPS wouldn't be calibrated against fixed ground positions. [[User:Baldrickk|Baldrickk]] ([[User talk:Baldrickk|talk]]) 22:06, 14 January 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I expect we'll be fine, but don't a lot of migratory critters use the Earth's magnetic field for navigation over very long distances? I mean, it's not as though they check a calendar and say, &amp;quot;Oh, hey, winter's coming, I guess I'd better head North.&amp;quot; They just go in the direction they are 'programmed' to go when they start to feel the urge to do so. So... If the poles reverse (or whatever else) aren't they going to go the wrong direction? There are lots of other species that rely on those migratory species for their lunch. Yeah, I can imagine that there could be a lot of problems. Assuming, of course, that what I read about migratory species using the magnetic field of the Earth for navigation is true.[[Special:Contributions/162.158.79.143|162.158.79.143]] 02:39, 15 January 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I don't believe any &amp;quot;location systems&amp;quot; depend on magnetic field for their accuracy, other than a magnetic compass.  As noted above, GPS is calculated numerically from signals received from satellites, so the only effect the magnetic field could have on that is if it somehow disrupts the broadcast of the satellite radio signals.  Similarly, LORAN calculates location based on radio signal, from towers on land.  There are others as well, and I'm pretty sure none that depend on the location of the magnetic pole.  GPS in general is not calibrated to fixed ground positions, but there are enhancements to GPS that do.  But those still use radio broadcasts from towers whose locations are known, and don't need to take into account the location of magnetic north.&lt;br /&gt;

&lt;br /&gt;
I agree that the way it is currently phrased is misleading (to the point of being wrong), but some &amp;quot;location systems&amp;quot; use multiple factors to increase their accuracy.  A good smartphone will use GPS together with signal strengths to wifi routers with known locations together with its compass to increase accuracy above that which it could obtain from GPS alone.  I've only taken little glimpses into the issue professionally but if I were making an algorithm for such a thing I'd also use input from the accelerometers.  In any event, I'd most certainly use the built-in compass.  Cheap estimation of direction of travel.  Of course I'm just being pedantic with all of that.  The difference in accuracy for such a scenario would most likely be minor to the point that nobody would notice.  I just kind of think the algorithms that try to combine all that sensor data are cool. --[[Special:Contributions/162.158.62.51|162.158.62.51]] 01:24, 15 January 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
Granted no one has ever experienced and documented a magnetic reversal event, however, would it be possible for the magnetic flux to cause errors on magnetic media? (eg HDD, credit cards, floppies, cassette, VHS, etc) If it were a cause for alarm, would a faraday cage be useful in protecting against the effects? [[Special:Contributions/172.68.34.34|172.68.34.34]] 23:05, 14 January 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
No.  Magnetic media would not be affected.  Geomagnetic field strengths are orders of magnitude weaker than those used to write to magnetic media. --[[Special:Contributions/162.158.62.51|162.158.62.51]] 01:27, 15 January 2019 (UTC)&lt;br /&gt;

GPS and Solar weather [https://www.swpc.noaa.gov/impacts/space-weather-and-gps-systems citation ] - worth a read. Basically, the ionosphere disturbance from a changing Earth field (analogous to a changing solar wind) leads to notable inaccuracy and service disruption.

The leftmost label says &amp;quot;10:00 AM EST&amp;quot;, but I'm 95% sure that it should be &amp;quot;5:00 AM EST&amp;quot;. That makes sense both in terms of time zones / date lines, and also in terms of the number of hash marks (the 9th hash mark before 1:30 PM: 2 PM - 9 = 5 AM). --Brandon [[Special:Contributions/172.69.22.224|172.69.22.224]] 19:35, 31 December 2018 (UTC)&lt;br /&gt;
:Agreed. The minor scale tick marks appear to be at 1 hr increments past the &amp;quot;1:30 PM&amp;quot; denoted time.

I'm actually not certain Randall '''suggests''' a time for universal celebration of New Year. Apart from the word &amp;quot;Consensus&amp;quot;, there's nothing to suggest it. Rather, I read it as a stated time where a majority will agree to the statement that it's now 2019. [[Special:Contributions/141.101.96.187|141.101.96.187]] 22:38, 31 December 2018 (UTC)Wilhelm&lt;br /&gt;

Nonetheless not only in California there are some people giving more attention to a much more unique event: New Horizons is passing {{w|(486958) 2014 MU69|Ultima Thule}}, six ''light hours'' away from Earth. &lt;br /&gt;

&lt;br /&gt;
On the topic of Orthodox churches using shifted Julian calendar: I can't speak for the entire world, but here in Russia it's not really relevant, since the church calendar is limited to religious matters, and New Year is a secular holiday.  (But Orthodox Christmas will in fact be observed on Jan 7th.)  There ''is'' an obscure holiday called Old New Year that is New Year shifted to 14th, but hardly anyone celebrates it and it certainly doesn't replace the regular one.

I note that 3:00PM (UTC-3) lists only &amp;quot;Northern&amp;quot; Brazil. That's kinda correct (should be actually &amp;quot;Northeastern&amp;quot; Brazil), but the South/Southwest, which is actually where the largest part of Brazilian population lives, is nowhere to be found. Due to DST, it ''should'' be in the 2:00PM line (UTC-2), but that line is blank.

'''Consensus Definition'''&lt;br /&gt;
&lt;br /&gt;
IP Address user 173.245.54.13 edited the explanation and replaced the Wikipedia definition references with an interpretation of how Randall incorrectly used the term &amp;quot;consensus&amp;quot; in place of majority vote - I don't agree that Randall has made any error, as I don't believe he intended consensus to represent majority vote. I'd like other opinions about restoring my original definitions in place of this new content, as I think it detracts from an understanding of the comic. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 22:35, 1 January 2019 (UTC)&lt;br /&gt;
&lt;br /&gt;
I eventually decided that &amp;quot;consensus New Year&amp;quot; meant &amp;quot;Agreement it is New Years,&amp;quot; more or less. As midnight marches past people, more people concede that it's the new year. To me, Mr M is just giving an interesting graph.&lt;br /&gt;
&lt;br /&gt;
: (BTW, you failed to sign your comment.) I like to think Randall is smarter than just using a word without understanding every nuance of it - after all, writing these comics is his full-time job instead of just a pastime. The fact that consensus is sometimes understood that way is the very reason why I thought the definition that states otherwise was useful and informative. The definitions included &amp;quot;average projected value&amp;quot; that seemed to match exactly how it was used in the title (by grammatical structure) and in the graph (by definition), so I'm of the opinion that Randall knew this as well and would not have misused the word outside of it's correct definition. I believe he created the graph to represent the &amp;quot;average projected value&amp;quot; of the metric at each point in time, very explicitly and meaningfully; to think otherwise seems to me to be an insult to his intelligence.

{{incomplete|Created by WINTER WHILE GETTING A SUNTAN. Need much more details on why it's bleak in the Winter in the middle. Also explain the title text Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
Middle latitudes are latitudes between the Arctic or Antarctic Circle (66 degrees North/South of the equator, respectively) and the Tropic of Cancer/Capricorn (23 degrees North/South of the Equator), two important latitudes on the globe that delineates some features of how the Sun rises and sets during the day.&lt;br /&gt;
&lt;br /&gt;
In the Northern hemisphere North of the Arctic Circle there is at least one day in the year when the sun doesn't set (in Summer) or doesn't rise (in Winter), below that latitude the sun will rise and set every day - even for a short time. Also in the North Hemisphere at any latitudes South of the Tropic of Cancer there is one day of the year where the sun will shine directly from above, while North of these latitudes there will be no such days, as the sun will always shine from an angle. The length of the day South of the Tropic of Cancer will also be close to 12 hours a day regardless of whether it is Summer or Winter. The length of the day in the middle latitudes will vary however, in the Winter time days are shorter, while in the Summer time days are longer. These are more visible the more one goes North, as close to the Arctic the sun will only rise for a few hours in the Winter, and similarly will only set for a few hours in the Summer.&lt;br /&gt;
&lt;br /&gt;
In the Southern hemisphere the situation is similar - any latitude South of the Antarctic Circle will have a day where there's no sun, and North of the Tropic of Capricorn there will be a time when the sun shines from directly above, and the length of the days are close to 12 hours the whole year. Between the two none of these will happen at any time of the year. Also days will be longer or shorter dependent on the season with Winter (centered around June in the Southern Hemisphere) having shorter days and Summer (centered around December) having longer (the opposite of how it is in the Northern hemisphere)&lt;br /&gt;
&lt;br /&gt;
The comic refers to these facts that inside the middle latitudes there are simply no interesting features at any time of the year, however in Winter (in the Northern Latitudes) the sun will set earlier, and generally because of the lower temperatures and shorter days it has a bleak feeling.&lt;br /&gt;
&lt;br /&gt;
The comic also plays on the idiom &amp;quot;split the difference&amp;quot; by applying it to the length of day vs. night.  To split the difference is to agree (or settle) on an amount of something, such as money, that is halfway between two others.  This can sometimes be characterized as a compromise where nobody gets what they want.&lt;br /&gt;
&lt;br /&gt;
Cueball starts by wishing to experience two extremes: normal sunrise and sunset, vs. weeks of 24-hour darkness.  Satisfying one or the other condition requires locating either to the Equator or to one of the poles.  Megan proposes a &amp;quot;split the difference&amp;quot; compromise, which turns out to involve dim, bleak winters.  Satisfying the compromise would mean locating in the &amp;quot;middle latitudes&amp;quot;.  Thus the bottom caption, &amp;quot;middle latitudes are the worst.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
The title text extends the idea.  Splitting the difference between &amp;quot;fun&amp;quot; snowy blizzards and &amp;quot;fun&amp;quot; warm sunny beaches would mean having neither, but instead icy wet slush.&lt;br /&gt;
&lt;br /&gt;
There are other comics that refer to the length of the day, and how it is different each day, a recent one for example is [[2050: 6/6 Time]]&lt;br /&gt;

:Cueball: It would be nice if the sun could rise and set at normal times. But it would also be cool to experience 24-hour darkness for weeks on end.&lt;br /&gt;
:Megan: Well, what if we split the difference, so all winter everything was normal but slightly more dim and bleak?&lt;br /&gt;
:Cueball: Perfect!&lt;br /&gt;

}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
Obviously, [[Beret Guy]]'s [[1021|business plan]] worked.&lt;br /&gt;
&lt;br /&gt;
Networking, in business, is the act of expanding your group of contacts in order to help your career down the line. Here, in this comic, [[Beret Guy]] meets Chief Technology Officer (CTO, an executive level position overseeing development of new technologies) Connr Clark (perhaps a typo for &amp;quot;Connor&amp;quot; or perhaps a reference to common &amp;quot;Web 2.0&amp;quot; names like the businesses {{w|Flickr}}, {{w|Tumblr}}, etc.) and Beret Guy is as strange as he usually is: he introduces himself as a &amp;quot;business professional&amp;quot; rather than as someone with any kind of specific job, and then goes on to mention that he photocopied a burrito, which he presumably believes is the sort of thing business professionals do. He also has a business card; usually this would contain contact information, but his only says &amp;quot;This is my business card&amp;quot;. He calls his briefcase, or suitcase, a &amp;quot;handlebox&amp;quot;, and it is full of a quarter of a million dollars in cash. Then Beret Guy proceeds to eat Connr's business card. All of these things are not common behavior.{{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Networking&amp;quot; is often an over-hyped, empty affair. There are zillions of networking meetings of every description going on every day everywhere, and mostly people trade cards and continue to not make money. So that's the joke – Beret Guy does the networking {{w|schtick}}, badly, and yet is somehow making huge amounts of money at it.&lt;br /&gt;
&lt;br /&gt;
The comic is also likely a joke on the idea that many people are excited about becoming a &amp;quot;business professional&amp;quot; who carries a briefcase, hands out business cards, and makes tons of money, without having an adequate plan for how to make those things happen, or possibly even knowing what their actual job would be. Beret Guy never says what he does, simply introducing himself as a &amp;quot;business professional,&amp;quot; and explains his piles of cash with &amp;quot;I am a business grown-up who makes business profits!&amp;quot; In this world —and in people's dreams— when you &amp;quot;grow up&amp;quot; and start a business, money magically appears. Obviously, that's not how it works.{{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
The &amp;quot;Eusocial&amp;quot; in &amp;quot;Eusocial Media Ventures&amp;quot; is a reference to {{w|eusociality}}, the highest level of social cooperation found in the animal kingdom.  Eusocial animals (termites being a common example) cooperate together to raise their young, have different generations living in the same colony, and have specialized individuals for reproductive and non-reproductive tasks.&lt;br /&gt;
&lt;br /&gt;
The title text is a pun on three common business buzzwords: agile, lean and long-tail. An agile business is one that can change course quickly based on customer demands and the business environment. A lean business is one with minimal inventory or assets; nothing is idle or warehoused, so everything in active use or on the move. Long-tail describes the strategy of offering a large number of unique items with relatively small quantities sold of each – usually in addition to selling fewer popular items in large quantities. Netflix is a popular example of long-tail because they have (almost) every movie imaginable, including rare titles that only a few people would be interested in.&lt;br /&gt;
&lt;br /&gt;
And of course, the pun here is one animal that is agile and lean with a long ''tail'' is a {{w|polecat}}.&lt;br /&gt;
&lt;br /&gt;
Furthermore, although &amp;quot;agile&amp;quot; and &amp;quot;lean&amp;quot; do mean a quick, nimble, and efficient business, they also refer to specific practices, as in {{w|agile software development}}, {{w|lean manufacturing}} and {{w|lean Six Sigma}}. Many people think these terms have devolved to overused jargon. While agile development is supposed to be a highly structured method to get programmers to produce more working code quickly, when someone from the marketing department says &amp;quot;''agile''&amp;quot; it often means &amp;quot;''We don't know what we're supposed to be producing, so we'll just chuck some stuff together, and keep those bits that the customer says he likes. We'll then do it all over again until we've got something that he'll pay for.''&amp;quot; &amp;quot;''Lean''&amp;quot; is supposed to mean that a business keeps its costs as low as possible, employing one person to do marketing and PR, not really having a Human Resources department, etc. But, in practice it often becomes &amp;quot;''Keep as little stock as possible so that we don't have a lot of money tied up in it, and don't need a big warehouse; make stuff just before it is supposed to ship so that we don't have to store it either; make frequent prayers and virgin sacrifices to whatever gods we can find to ensure that nothing slips up anywhere along the line that our lawyers can't get us out of.''&amp;quot;&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a Basketball - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
At the time of this comic, the {{w|2018 NBA Finals}} were going on, between the {{w|Cleveland Cavaliers}} and the {{w|Golden State Warriors}} with the Warriors leading 2 games to 0 in a best of seven series. At first glance, the comic looks like an in-depth analysis of two of the star players on those teams, {{w|LeBron James}} and {{w|Stephen Curry}}. The joke is that while comprehensive, all the statistics are completely meaningless - many don't show any correlation, and if there is one, it's extremely unlikely there is any causal link in there. &lt;br /&gt;
&lt;br /&gt;
The first graph includes a nine-digit {{w|Social Security number}} issued for US citizens which is typically not considered a metric related to athletic ability. As Social Security numbers are essentially random numbers ([https://www.ssa.gov/employer/randomization.html until 2011], there was a geographic correspondence for the first three digits), the graph shows only the free-throw percentage of a large number of players, artificially spread vertically. Also note that Social Security numbers are not usually made public, barring security leaks.&lt;br /&gt;
&lt;br /&gt;
The second graph is a graph of points per game vs teammate's APGAR score. {{w|APGAR score}} is used to quickly summarize the health of newborn children, with scores of 7 and above indicating an infant has generally normal health; its use to rank adult NBA players is odd, if not improper. This graph indicates LeBron's teammates have an APGAR score of approximately 2.1. Scores of 3 and below are generally regarded as critically low and possibly requiring medical attention. Low APGAR scores can also be associated with increased risk of neurological disorders such as cerebral palsy. The joke appears to be that LeBron is a star player carrying a sub average team while their opponents the Warriors are perhaps a more well rounded team.&lt;br /&gt;
&lt;br /&gt;
The shot map shows from what position Curry's shots were scored compared to other NBA players. It shows that he scored several times from outside the playing field, including twice from the {{w|bleacher}}s (which isn't a legal play), and once from the locker room (which is physically impossible due to multiple walls in between). This may be a reference to Curry's &amp;quot;tunnel-shot&amp;quot;, which he performs before every home game.[https://www.sfchronicle.com/warriors/article/Stephen-Curry-s-long-tunnel-shot-has-become-10949145.php] &lt;br /&gt;
&lt;br /&gt;
In the &amp;quot;2018 total points&amp;quot; table, the highlighted {{w|Golden State Warriors}} and {{w|Cleveland Cavaliers}} represent the teams of Stephen Curry and LeBron James respectively.&lt;br /&gt;
&lt;br /&gt;
Magnetic north is the north pole of the earth's magnetic field. Certain animals use the magnetic field to navigate and align themselves (including migratory birds, bees, and foxes), but there is no evidence that humans are affected by the earth's magnetic field. This means that there is very likely no correlation between orientation of a basketball court and points scored.&lt;br /&gt;
&lt;br /&gt;
The table at the bottom includes more unrelated comparisons.&lt;br /&gt;
&lt;br /&gt;
The first fact is &amp;quot;have you heard of him&amp;quot;. Although both are well known in their native United States, elsewhere basketball is considered a minority sport. So of the 7 billion people in the world it is likely less than 2% of the total population will have heard of either player {{Citation needed}}.&lt;br /&gt;
&lt;br /&gt;
In NBA the top 16 teams qualify for a single elimination play-off to determine the season champion, with each rubber played over 7 games. After the fourth game fixtures are only played as required. Most fixtures are therefore resolved before the last leg. Lebron James has participated in seven playoff games 7 in his career (winning 5 of 7), and the last time his team lost a game seven was on May 18, 2008 (Bush was still President). This also highlights that James is an older athlete yet has been fairly dominant through his career. Stephen Curry's last game 7 loss actually came at the hands of Lebron James in the 2016 NBA Finals (Obama was President). It is notable that both the Golden State Warriors and Cleveland Cavaliers won their respective games 7 in their conference finals to make it to this year's NBA finals.&lt;br /&gt;
&lt;br /&gt;
Both &amp;quot;lebronjames&amp;quot; and &amp;quot;stephencurry&amp;quot; are worth 22 points in {{w|Scrabble}}. {{w|Milk caps (game)|Pogs}} were a {{w|fad}} in the 1990s. In 2027, Stephen Curry will be 39 years old, which is a typical retirement age for NBA players. LeBron James's retirement age is listed as ''unknown''. This may refer to James's high level of play through his mid-30s, when typical players have a decline in their performance {{Citation needed}}. &lt;br /&gt;
&lt;br /&gt;
It is claimed that their best sport is basketball. However, although they have chosen basketball as a career, this does not mean they were not better at a sport that does not offer a professional career.&lt;br /&gt;
&lt;br /&gt;
Both are listed as over 6 feet tall which is not at all unusual for professional basketball players. In fact, Stephen is listed as 6'2&amp;quot; or 6'3&amp;quot; and LeBron as 6'8&amp;quot;.   &lt;br /&gt;
&lt;br /&gt;
{{w|Nate Silver}} is a political commentator and founder of the website {{w|FiveThirtyEight}}, which uses and promotes statistical approaches in explaining the world.  The site's two major areas of focus are in politics (especially on elections - it became famous for correctly predicting for whom 49 of 50 of the 2008 and every US state would vote for in the 2012 US presidential elections, and though it wasn't as accurate in 2016 it had given Donald Trump a larger chance of Electoral College victory than other mainstream media sources) and sports (Silver first got into statistical analysis via baseball). The presence of both sports-related and politics-related topics in the comic, however related they are (or not) with each other, seems to be a nod towards FiveThirtyEight's content.&lt;br /&gt;

&lt;br /&gt;
:[The comic consists of several plots and tables, listed here in western reading order.]&lt;br /&gt;
&lt;br /&gt;
:'''Scatter plot of Social Security number vs Free throw percentage'''&lt;br /&gt;
:The Social Security numbers range from 000-00-0000 to 999-99-9999. No pattern discrenable, aside from points being a bit denser in the middle of the plot. Steven Curry is marked as a point on the right edge of the plot with a high free throw percentage.&lt;br /&gt;
&lt;br /&gt;
:'''Scatter plot of 2018 points per game vs Average teammate APGAR score'''&lt;br /&gt;
:The APGAR scores range from 0 to 10. Pattern suggests a somewhat positive link between the two factors. LeBron James is marked as having a lot of points, but a low teammate APGAR score of approximately 2.1.&lt;br /&gt;
&lt;br /&gt;
:'''Shot map'''&lt;br /&gt;
:A diagram of a basketball court is shown with dots placed where players have taken shots at the goal. Steven Curry has dots in a separate color. For the all players category the dots generally cluster next to the goal basket and in front of the three point line. Steven has no dots next to the basket, but does cluster next to the three point line. He also has several dots off the side of the playing field, including three in the bleachers and one in the locker room.&lt;br /&gt;
&lt;br /&gt;
:'''Sandwiches eaten during play vs Win %'''&lt;br /&gt;
:A plot that suggests no relation between the factors because practically all dots are in the zero sandwiches column. 2018 Warriors have one dot marked as a high win % and 4 sandwiches.&lt;br /&gt;
&lt;br /&gt;
:'''2018 total points'''&lt;br /&gt;
:A table listing teams and their total scores with an extra column labeled &amp;quot;When net is within 15° of magnetic north&amp;quot;. The row for the Cleveland Cavaliers is highlighted and shows an abnormally high score in the magnetic north column.&lt;br /&gt;

==Trivia==&lt;br /&gt;
This comic was posted the day after the second game in the 2018 NBA Finals between the Golden State Warriors (Stephen Curry's team) and the Cleveland Cavaliers (LeBron James' team).  It is the fourth consecutive time the two teams faced each other at the finals, which is unprecedented in major sports leagues in North America.  The Warriors won in 2015 and 2017, the Cavaliers won in 2016, and the Warriors are leading the current series 2-0.&lt;br /&gt;

At the time of this comic, the {{w|2018 NBA Finals}} were going on, between the {{w|Cleveland Cavaliers}} and the {{w|Golden State Warriors}} with the Warriors leading 2 games to 0 in a best of seven series. At first glance, the comic looks like an in-depth analysis of two of the star players on those teams, {{w|LeBron James}} and {{w|Stephen Curry}}. The joke is that while comprehensive, all the statistics are completely meaningless - many don't show any correlation, and if there is one, it's extremely unlikely there is any causal link in there. &lt;br /&gt;
&lt;br /&gt;
The first graph includes a nine-digit {{w|Social Security number}} issued for US citizens which is typically not considered a metric related to athletic ability. As Social Security numbers are essentially random numbers ([https://www.ssa.gov/employer/randomization.html until 2011], there was a geographic correspondence for the first three digits), the graph shows only the free-throw percentage of a large number of players, artificially spread vertically. Also note that Social Security numbers are not usually made public, barring security leaks.&lt;br /&gt;
&lt;br /&gt;
The second graph is a graph of points per game vs teammate's APGAR score. {{w|APGAR score}} is used to quickly summarize the health of newborn children, with scores of 7 and above indicating an infant has generally normal health.  This graph indicates LeBron's teammates have an APGAR score of approximately 2.1.  Scores of 3 and below are generally regarded as critically low and possibly requiring medical attention.  Low APGAR scores can also be associated with increased risk of neurological disorders such as cerebral palsy.  The joke appears to be that LeBron is a star player carrying a sub average team while their opponents the Warriors are perhaps a more well rounded team.&lt;br /&gt;
&lt;br /&gt;
The shot map shows from what position Curry's shots were scored compared to other NBA players. It shows that he scored several times from outside the playing field, including twice from the {{w|bleacher}}s (which isn't a legal play), and once from the locker room (which is physically impossible due to multiple walls in between). This may be a reference to Curry's &amp;quot;tunnel-shot&amp;quot;, which he performs before every home game.[https://www.sfchronicle.com/warriors/article/Stephen-Curry-s-long-tunnel-shot-has-become-10949145.php] &lt;br /&gt;
&lt;br /&gt;
In the &amp;quot;2018 total points&amp;quot; table, the highlighted {{w|Golden State Warriors}} and {{w|Cleveland Cavaliers}} represent the teams of Stephen Curry and LeBron James respectively.&lt;br /&gt;
&lt;br /&gt;
Magnetic north is the north pole of the earth's magnetic field. Certain animals use the magnetic field to navigate and align themselves (including migratory birds, bees, and foxes), but there is no evidence that humans are affected by the earth's magnetic field. This means that there is very likely no correlation between orientation of a basketball court and points scored.&lt;br /&gt;
&lt;br /&gt;
The table at the bottom includes more unrelated comparisons.&lt;br /&gt;
&lt;br /&gt;
The first fact is &amp;quot;have you heard of him&amp;quot;. Although both are well known in their native United States, elsewhere basketball is considered a minority sport. So of the 7 billion people in the world it is likely less than 2% of the total population will have heard of either player {{Citation needed}}.&lt;br /&gt;
&lt;br /&gt;
In NBA the top 16 teams qualify for a single elimination play-off to determine the season champion, with each rubber played over 7 games. After the fourth game fixtures are only played as required. Most fixtures are therefore resolved before the last leg. Lebron James has participated in seven playoff games 7 in his career (winning 5 of 7), and the last time his team lost a game seven was on May 18, 2008 (Bush was still President). This also highlights that James is an older athlete yet has been fairly dominant through his career. Stephen Curry's last game 7 loss actually came at the hands of Lebron James in the 2016 NBA Finals (Obama was President). It is notable that both the Golden State Warriors and Cleveland Cavaliers won their respective games 7 in their conference finals to make it to this year's NBA finals.&lt;br /&gt;
&lt;br /&gt;
Both &amp;quot;lebronjames&amp;quot; and &amp;quot;stephencurry&amp;quot; are worth 22 points in {{w|Scrabble}}. {{w|Milk caps (game)|Pogs}} were a {{w|fad}} in the 1990s. In 2027, Stephen Curry will be 39 years old, which is a typical retirement age for NBA players. LeBron James's retirement age is listed as ''unknown''. This may refer to James's high level of play through his mid-30s, when typical players have a decline in their performance {{Citation needed}}. &lt;br /&gt;
&lt;br /&gt;
It is claimed that their best sport is basketball. However, although they have chosen basketball as a career, this does not mean they were not better at a sport that does not offer a professional career.&lt;br /&gt;
&lt;br /&gt;
Both are listed as over 6 feet tall which is not at all unusual for professional basketball players. In fact, Stephen is listed as 6'2&amp;quot; or 6'3&amp;quot; and LeBron as 6'8&amp;quot;.   &lt;br /&gt;
&lt;br /&gt;
{{w|Nate Silver}} is a political commentator and founder of the website {{w|FiveThirtyEight}}, which uses and promotes statistical approaches in explaining the world.  The site's two major areas of focus are in politics (especially on elections - it became famous for correctly predicting for whom 49 of 50 of the 2008 and every US state would vote for in the 2012 US presidential elections, and though it wasn't as accurate in 2016 it had given Donald Trump a larger chance of Electoral College victory than other mainstream media sources) and sports (Silver first got into statistical analysis via baseball). The presence of both sports-related and politics-related topics in the comic, however related they are (or not) with each other, seems to be a nod towards FiveThirtyEight's content.&lt;br /&gt;

:'''LeBron James and Stephen Curry'''&lt;br /&gt;
:'''What makes these superstars so extraordinary?'''&lt;br /&gt;
&lt;br /&gt;
:[The comic consists of several plots and tables, listed here in western reading order.]&lt;br /&gt;
&lt;br /&gt;
:'''Scatter plot of Social Security number vs Free throw percentage'''&lt;br /&gt;
:The Social Security numbers range from 000-00-0000 to 999-99-9999. No pattern discrenable, aside from points being a bit denser in the middle of the plot. Steven Curry is marked as a point on the right edge of the plot with a high free throw percentage.&lt;br /&gt;
&lt;br /&gt;
:'''Scatter plot of 2018 points per game vs Average teammate APGAR score'''&lt;br /&gt;
:The APGAR scores range from 0 to 10. Pattern suggests a somewhat positive link between the two factors. LeBron James is marked as having a lot of points, but a low teammate APGAR score of approximately 2.1.&lt;br /&gt;
&lt;br /&gt;
:'''Shot map'''&lt;br /&gt;
:A diagram of a basketball court is shown with dots placed where players have taken shots at the goal. Steven Curry has dots in a separate color. For the all players category the dots generally cluster next to the goal basket and in front of the three point line. Steven has no dots next to the basket, but does cluster next to the three point line. He also has several dots off the side of the playing field, including three in the bleachers and one in the locker room.&lt;br /&gt;
&lt;br /&gt;
:'''Sandwiches eaten during play vs Win %'''&lt;br /&gt;
:A plot that suggests no relation between the factors because practically all dots are in the zero sandwiches column. 2018 Warriors have one dot marked as a high win % and 4 sandwiches.&lt;br /&gt;
&lt;br /&gt;
:'''2018 total points'''&lt;br /&gt;
:A table listing teams and their total scores with an extra column labeled &amp;quot;When net is within 15° of magnetic north&amp;quot;. The row for the Cleveland Cavaliers is highlighted and shows an abnormally high score in the magnetic north column.&lt;br /&gt;

==Trivia==&lt;br /&gt;
This comic was posted the day after the second game in the 2018 NBA Finals between the Golden State Warriors (Stephen Curry's team) and the Cleveland Cavaliers (LeBron James' team).  It is the fourth consecutive time the two teams faced each other at the finals, which is unprecedented in major sports leagues in North America.  The Warriors won in 2015 and 2017, the Cavaliers won in 2016, and the Warriors are leading the current series 2-0.&lt;br /&gt;
