This comic is loosely related to a series of comics related to the 2020 pandemic of the coronavirus SARS-CoV-2, which causes COVID-19. <br />
<br />
The comic hinges on sharing photos on social media of vaccination cards as proof that the user has been {{w|COVID-19 vaccine|vaccinated against COVID-19}} (in this case, gotten a {{w|Booster dose|booster shot}}). When the first U.S. recipients received their vaccine, a large number shared photos of the CDC vaccination card; it was enough of a trend that the {{w|Federal Trade Commission|FTC}} released an official statement warning vaccine recipients [https://www.consumer.ftc.gov/blog/2021/02/social-media-no-place-covid-19-vaccination-cards not to share photos] due to the cards containing {{w|Personal data|personal identification}} that should probably not be made public. <br />
<br />
The irony is that the user has {{w|Sanitization (classified information)|"censored"}} some impersonal lines, such as the instructions that are identical on all vaccination cards, and many easy-to-guess lines, while not censoring any of said personal information.<br />
The fourth line, labelled "other" is probably completely blank (as the third dose was on the day immediately prior to the publication one), but is completely blacked out.<br />
<br />
The caption indicates that his intention is to "seem more mysterious". This is best exemplified by blanking most of the word "clinician" to leave the acronym "{{w|Central Intelligence Agency|CIA}}", referring to a US government agency known for its frequently "mysterious" (classified) activity, as well as its liberal use of redaction like that in the comic.<br />
<br />
This is the first comic including a sentence in Spanish.<br />
<br />
Randall's patient number is the 2nd to 9th decimals of {{w|pi}} inclusively: 41592653<br />
<br />
The date of birth on the card corresponds to the date of birth given in an earlier version of his English wikipedia article (other languages still do). It is unclear if the author plays into a false rumor or has used his actual birthday.<br />

The purpose of clinical trials in medicine is to make sure that a new medicine works and doesn't have serious side-effects. One example of the dangers of failing to make sure that it doesn't have serious side effects is thalidomide, which caused a lot of birth defects.<br />

==Explanation==<br />
{{incomplete|Created by ALANIS TURINGETTE - Please change this comment when editing this page. Do NOT delete this tag too soon.}}<br />
This comic plays a joke on the common liquid measurements of {{w|teaspoon}}s (tsp) and {{w|tablespoon}}s (tbsp), which are commonly confused. A teaspoon is defined as 5 mL (0.18 imp fl oz; 0.17 US fl oz) while a tablespoon is defined as 14.8 ml (0.50 US fl oz; 3 tsp) in the US.<br />
<br />
It also plays a joke on metric measurements (which use powers of 10) versus computer measurements (which use powers of 2), which also cause confusion. See also [[394: Kilobyte]].<br />
<br />
The title text is a play on a lyric from the Alanis Morissette song "{{w|Ironic (song)|Ironic}}": "It's like ten thousand spoons when all you need is a knife." Randall changes the line to "teraspoon" and "kilonife".<br />
<br />
If "spoon" is understood as teaspoon, then one teraspoon will be 5000 cubic meters and a binary teraspoon will be 5497,6 cubic meters. If the tablespoon is taken as base unit, a teraspoon will be 14800 cubic meters and a binary teraspoon 16272.8 cubic meters. Both volumes are much too large to fit inside a typical residential kitchen.{{Citation needed}}<br />

==Explanation==<br />
{{incomplete|Title text not explained. More details before the list.}}<br />
<br />
This comic is a series of programming jokes about a ridiculous new programming language, perhaps inspired by [https://www.destroyallsoftware.com/talks/wat Gary Bernhardt's CodeMash 2012 lightning talk] on Javascript's unpredictable typing. The (highly technical) audience is unable to correctly guess the results of adding various Javascript types and roars with laughter when they're revealed.<br />
<br />
Most regular programming languages distinguish a number of types, e.g. integers , strings, lists,... All of which have different behaviours. The operation "+" is conventionally defined over more than one of these types. Applied to two integers, it returns their addition, but applied to two strings (denoted by being enclosed in quotes) it concatenates them:<br />
<br />
<code>> 2 + 3<br />
<br />
5<br />
<br />
> "123" + "abc"<br />
<br />
"123abc"</code><br />
<br />
While these behaviours are standard, conventional, and intuitive, there is a huge amount of variation among programming languages when you apply an operation like "+" to different types. One logical approach is to always return an error in all cases of type mixing, but it is often practical to allow some case mixing, since it can hugely simplify an operation. Variation and lack of a clearly more intuitive behaviour leads some languages to have weird results when you mix types.<br />
<br />
# <code>2 + "2"</code> uses the <code>+</code> operator on a number and a string. In a normal language, this would result either the number <code>4</code> (addition), or <code>"22"</code> (string concatenation); however, the new language converts the string to an integer, adds them to produce <code>4</code> and converts back to a string. Alternately, it is adding 2 to the ASCII value of the character <code>"2"</code>, which (interpreted as a string) is <code>"4"</code>. This is (somewhat) consistent with the behavior for item 4.<br />
# <code>"2" + []</code> adds a string to an array or list, this time. This first inexplicably converts the string to a number again, and then it literally adds the number to the list by appending it (this would make sense if it was <code>[] + 2</code>, but usually not the other way around). And then the result (the entire array) is converted to a string again.<br />
# <code>(2/0)</code> divides <code>2</code> by <code>0</code> and quite reasonably results in <code>NaN</code> (not a number).<br />
# <code>(2/0)+2</code> adds <code>2</code> to <code>NaN</code>. <code>2</code> is "added" to the string <code>"NaN"</code> (again, the number is converted to a string for apparently no reason), which produces <code>"NaP"</code>, as if <code>2</code> was added to <code>"N"</code> to produce <code>"P"</code> (as per alphabetical order or ASCII encoding; <code>N</code> is <code>01001110</code>, and adding 2 to this results in <code>01010000</code> which is <code>P</code>).<br />
# <code>""+""</code> looks like it is concatenating (adding) an empty string (i.e. <code>""</code>) to another empty string, which should produce an empty string. However, the entire thing is treated as one string (with the start quote being the first one and the end quote being the very last one), which produces the egregious '<code>"+"</code>'.<br />
# <code>[1,2,3]+2</code> seems to test whether it's sound to append <code>2</code> to the list <code>[1,2,3]</code>, and concludes that it doesn't fit the pattern, returning the boolean value <code>false</code>. It could conceivably also be the result of an attempt to add <code>2</code> to the ''set'' <code>[1,2,3]</code>, which already contains that element (although <code>{1,2,3}</code> would be a more common notation for sets).<br />
# <code>[1,2,3]+4</code> returns <code>true</code> for much the same reason.<br />
# <code>2/(2-(3/2+1/2))</code> is a floating point joke. Floating point numbers are notoriously imprecise. With precise mathematics, <code>(3/2+1/2)</code> would be exactly 2, hence the entire thing would evaluate to <code>2/0</code> or <code>NaN</code> in Randall's new language. However, the result of <code>(3/2+1/2)</code> is "just slightly off," which makes the result "just slightly off" of <code>NaN</code> (which would be ridiculous in a real language). The ironic thing is that fractions with 2 in the denominator are ''not'' the kind of numbers that typically suffer from floating point impreciseness. Additionally, if there was indeed a rounding error, the actual calculation becomes something like <code>2/0.0000000000000013</code>, which should not return a <code>NaN</code> since it is not division by zero.<br />
# <code>range(" ")</code> normally wouldn't make any sense. However, the new language appears to interpret it as ASCII, and in the ASCII table, character #32 is space, #33 is <code>!</code>, and #34 is <code>"</code>. So, instead of interpreting <code>" "</code> as a string, it seems to be interpreted as <code>34, 32, 34</code> (in ASCII), and then <code>range</code> appears to transform this into <code>34, 33, 32, 33, 34</code> (the "ranges" between the numbers), which, interpreted as ASCII, becomes <code>['"', '!', ' ', '!', '"']</code>.<br />
# <code>+2</code> refers to the Chinese/Japanese (Kanji) number system, where the plus sign is instead the symbol <code>十</code>. In Chinese, this symbol represents the number ten, and if you translate the <code>2</code> into Chinese, you get <code>二</code>. Therefore, in full Chinese the code is <code>十二</code> is equivalent to the number <code>12</code>. Alternately, it could simply be attempting to add 2 to the line number 10 to get 12.<br />
# <code>2+2</code> would normally be <code>4</code>. However, the interpreter takes this instruction to mean that the user wishes to increase the actual value of the number <code>2</code> (aka the "literal value") by <code>2</code> for the remainder of the program, making it <code>4</code> and then reports that the work is "Done". The result can be seen in the subsequent lines where all <code>2</code>s are replaced by <code>4</code>s. This could be a reference to languages like Fortran where [http://everything2.com/title/Changing+the+value+of+5+in+FORTRAN literals could be assigned new values].<br />
# <code>range(1,5)</code> would normally return <code>[1, 2, 3, 4, 5]</code>. However, since the value of <code>2</code> has been changed to <code>4</code>, it returns <code>[1, 4, 3, 4, 5]</code>, and this even affects the line number (which is 14 instead of 12). <br />
# <code>floor(10.5)</code> should return <code>10</code> (the "floor" of a decimal number is that number rounded down). However, it instead returns {{w|ASCII art}} of the number on a "floor."<br />
<br />
The title text contains three further examples relating to color. <code>color.rgb("blue")</code> returns the hexadecimal code for pure blue (as would be used in HTML, for example), which is how a real programming language might work. The lookup for "yellowish blue" returns "NaN" (Not a Number) again, which makes sense at one level because there is no such color as "yellowish blue" (yellow and blue make green). However a more typical result would have been a failure indicating that the color database does not include the name, in the same way that a typo such as "bluw" would. Similarly sorting the colors would normally produce some defined ordering, such as alphabetical, but in this language it generates the string "rainbow". It seems that Randall's new language understands color theory in an unusually deep way.<br />

Although I personally prefer Android phones for their OS flexibility, I don't think the "Android has longer battery life than iPhone" comment is needed in the explanation. It feels very opinionated, out of place and dubious (battery life essentially depends on usage.) That comment distracts from the main point of the comics. The comment the screenshot is of an iPhone and the phone itself is an Android is quite relevant since both status bars are vastly different (something that a casual reader might not realize), yet the phone owner is still confused by the screenshot's battery icon. If someone wants to reword that in the description better than I could do, please help yourself. [[User:Ralfoide|Ralfoide]] ([[User talk:Ralfoide|talk]]) 17:56, 26 May 2014 (UTC)<br />
:The iPhone vs Android jab in the explanation was totally trolling, lame. Android phones as a rule have much inferior battery life to iPhone over the span of the day - and the reason for that are design decisions in making of iOS vs Android. For example iOS is total nazi in not allowing background processes to run (spare ones actively playing music or GPS, plus limited time downloads). On Android OTOH, apps relish attaching themselves to the many system hooks, to be launched/notified on changes - so as practical matter you always have Maps, Play store, Google Play Services and user apps leeching on the battery. Android has advantages over iOS (there are many thing you can do that are verboten in iOS) - but battery life, as well as privacy control are not one of them. Please let the explanation be w/o getting into platform war - it is about being OCD, not mobile OSes. {{unsigned ip|199.27.128.167}}<br />

My read on this is he's distracted from the call for help, "Help, my battery won't charge! See!", because the attached image shows a low battery, killing his respect for the sender. Maybe that's just me. [[Special:Contributions/108.162.221.51|108.162.221.51]] 23:13, 26 May 2014 (UTC)<br />

Some of the reason for this is the android sdk is used to create these screenshots.<br />
The sdk contains some virtual machines and these have the battery detect as being low.<br />
This seems to be done on purpose as you could query the charge of your phone in an app and having this set to in the middle makes it easier to test your app.<br />
It is much easier to take a photo with the sdk than to use real hardware as phones will be different and you will have other applications running that you don't want to be included in the screen shot.<br />

: …except it isn’t! iPhones don’t get to use the Android SDK, and they have screenshot functionality since day one. Modern Android phones also have that capability. And no, making screenshots on the VMs is not easier: the SDK requires proficiency with Android, computers in general and much more; you can’t have the texts that you want to have a screenshot of on the VM; it’s generally slow and worthless. Such screenshots are created with physical phones, of people too lazy to charge their phones. —Chris Warrick/[[Special:Contributions/141.101.88.216|141.101.88.216]] 15:43, 27 May 2014 (UTC)</div>108.162.215.65https://www.explainxkcd.com/wiki/index.php?title=Talk:633:_Blockbuster_Mining&diff=56369Talk:633: Blockbuster Mining2014-01-01T20:57:44Z<p>108.162.215.65: "stop I'll talk frame suggestion"</p>

The "rectangular object" appears to be be the spiral bound notebook when looked at closely. Or is it just me?<br />

Do we know which particular action scenes of which particular movies are satirized in each frame? I get the feeling they're either extremely generic or from something familiar. [[Special:Contributions/108.162.226.228|108.162.226.228]] 15:28, 1 January 2014 (UTC)<br />

The one in the "stop I'll talk" frame reminds me of the scene in Mission Impossible III (I think three) where the bad guy gets the info and then shoots the girlfriend anyway, however it could be from any movie. It was my impression that the panels are more of a "spy goes bananas" aspect so this could just be a reference to the stereotypical spy information extraction tactic gone awry.<br />

I beg to differ on the flux capacitor thing, as cool as it sounds. Since it is right above the I-90 notation, it is more likely a fork in the road (notice the road stripes indicating that you can pass at any point in the fork).

: Oh, I'm pretty sure it's a flux capacitor. Compare some of [http://www.google.com/search?q=flux+capacitor&tbm=isch these images]. Yes, there are several road references in this comic, but an electronic reference (especially to a ''fictional'' electronic component!) makes more sense. Also I've never seen a Y-shaped highway intersection that looked quite like that (and especially not on an interstate). —[[User:Scs|Scs]] ([[User talk:Scs|talk]]) 14:52, 17 November 2013 (UTC)<br />

I have wasted 4 hours on the puzzle, and after wasting 9 pages of A5 paper, the resistance of that terrible resistor mess worked out to be exactly 25265/33783 ohm, or about 0.74786135 ohm. --KopaLeo [[Special:Contributions/199.48.226.89|199.48.226.89]] 15:16, 27 June 2013 (UTC)<br />

I think the attempt to explain every single piece of the comic is rather silly.
