Don't most people say "on three", "on one", or "on go" before starting the count anyway? And then delay the final (action) number a teensy bit? e.g. "On one. Ready? 3 2 1" This isn't that ambiguous, not that I would object to standardisation. [[User:Sameldacamel34|Sameldacamel34]] ([[User talk:Sameldacamel34|talk]]) 23:13, 13 April 2026 (UTC)
:It is appallingly common for me to hear the inconsistent and dissonant, "On the count of three…one, two, three, GO!"

:There are two different conventions to synchronize a start -- by reacting or by rythmically coordinating.

And the Lord spake, saying, "First shalt thou take out the Holy Pin. Then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out.

Somewhat related, is is quite common for someone to have filenames like "Thesis (final)", "Thesis (really final)", "Thesis (really really final)" (instead of "Thesis" it might be "Presentation"). I have just checked the RCS log of my MSc Thesis: the 2.16 version was the final, but then there were the 3.1 and 3.2, which were the correction of two typos.

''"append "Copy of" to the start of the filename"'' Append comes after. I think the word we want is "'''prepend'''". Not as familliar as append, but Google reports wide and serious usage. A further note: MS's hack ruins the idea of alphabetized filenames, all the "Copy of" in one place. --[[User:PRR|PRR]] ([[User talk:PRR|talk]]) 21:24, 17 March 2025 (UTC)

:: The older and still probably more common meaning of "append" is just "attach", with no particular implication of where (e.g. https://en.wiktionary.org/wiki/append#English). The narrower sense of "add at the end", and the back-formation "prepend" for "add at the beginning", are relatively recent, and mostly computing jargon. Apparently, there's also occasional use of "postpend" as the complement of "prepend", but I don't think I've ever come across it in the wild.
:: So, either "append to the start" or "prepend" is fine, I think.

3034: Features of Adulthood

2025-01-07T09:45:10Z

IMSoP: tarpaulin would be a *terrible* material to make a parachute out of

{{comic
| number = 3034
| date = January 6, 2025
| title = Features of Adulthood
| image = features_of_adulthood_2x.png
| imagesize = 704x620px
| noexpand = true
| titletext = I don't dig pit traps and cover them with sticks and a thin layer of leaves nearly as much as I expected; I find a chance to do it barely once a month.
}}

==Explanation==
{{incomplete| Unexpectedly created by an adult BOT digging pit traps - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic is a graph comparing the (mostly) common ideas of adulthood from a young person's perspective with the sad reality of it. The features that are most expected but don't actually come up (quicksand, grappling hooks, crocodiles, and twins switching place) are common tropes in fiction. At the opposite end, some very mundane activities are common but we don't expect them to be important when we're young: deciding what to eat, dealing with weird noises and smells.

It is clear that many of the things that were imagined more likely than they turned out to be are ''direct'' references to fictional scenarios on film or TV, especially with a number of action movie tropes, throughout the 'lower-right triangle'. In contrast, the complimentary 'upper-left triangle' has situations that mostly (though not entirely!) seem to not be portrayed in many fictional depictions.

|-

| 0%
| Explosives with visible lit fuses are commonly seen in movies and TV shows. In reality, explosives are more likely to be remotely detonated or have an {{w|time bomb|unlit}} or concealed fuse (e.g. {{w|grenade}}s). Also, most people don't generally have to deal with explosives anyway.

|-
| {{w|Quicksand}}

| Quicksand is {{tvtropes|QuicksandSucks|common in adventure fiction}}, but it's quite rare in real life, and an average person is highly unlikely to encounter quicksand in day to day life.{{cn}}
|-
| {{w|Car chase}}s
| 35%
| 5%
| Car chases are frequently seen in movies and TV shows involving police. But unless you're a police officer or criminal trying to evade them, you'll probably never be involved in one. Possibly the only actual car chase many people have actually seen is {{w|O.J.Simpson}}'s white Ford Bronco, which was shown on TV after he was identified as the prime suspect in his wife's murder.
|-
| {{w|Grappling hook}}s
| 100%
| 5%
| A grappling hook is a metal piece that is attached to a rope. If the person is going up a cliff, the “hook” would be thrown or shot at the top of the cliff and would either snag something, or more commonly, would wrap around something like a tree then hook onto itself, thus securing a way up the cliff.
|-
| People offering free drugs
| 30%

| Typically refers to illicit drugs. The expectation is that a drug pusher will offer you free samples to get you addicted, then start charging expensive prices.

|-

| 95%
| 10%
| Wooden or {{w|Drum (container)|metal}} storage implements, frequently used as concealment, improvised weapons and (sometimes explosive) obstacles in popular media.
|-
| {{w|Middle name}}s
| 15%
| 20%
| A second (or occasionally also third or more) {{w|given name}}, common in some traditions. Sometimes used specifically to honor someone (perhaps the same first name of a grandparent or loved one, occasionally such a person's surname). It can be used as further identification, if one has a common first and last name. In some families, the first name may be traditionally shared with the appropriate parent (and the grandparent, their parent) and reference by the middle name(s), alone, may be more useful to distinguish the person being addressed from within a family situation. In later life, a person may drop the use of middle names (or, conversely, adopt ''only'' them as the name they are known by) and the unweildy complete set of names becomes less common, as they may be considered unprofessional and unnecessary.
Authors and politicians may most obviously buck this trend, as they have to develop an identity far beyond their immediate personal and professional circles, and perhaps need to be more disambiguously individual and free of confusion from others of similar named as "Firstname Surname", but this might also just reflect that the practice of more formally complete names is a tradition that is being dropped from those of [[Randall]] (Patrick) Munroe's generation, leaving only the generations before (most represented, in the public eye, by elder statesmen and well-read writers) still using them in the way they always did.

IMSoP: grilled cheese

As Wikipedia notes, the {{w|Harvard comma}} is actually a thing, and synonymous with the Oxford comma. It's hard to understand whether Randall was just ignoring that.
It's interesting to also look at how the various commas are meaningful. For instance, the Yale comma here appears to be just plain ungrammatical, you'd never put a comma between a verb and a its direct object; similarly the Cambridge comma and Princeton commas are ungrammatical, you'd never put one after the word "and." The Stanford comma is unambiguously normal and it's not clear how you could have such a list without it (absent replacement with a [Stanford?] semicolon). The Columbia comma is being used to separate "mac and cheese" into "mac, and[,] cheese" which changes the semantic meaning (arguably into something meaningless, but maybe we're listing Apple Computers or even Macintosh apple fruit abbreviated). The MIT comma is a cute programming joke for multiline lists. Maybe there are hidden trick meanings (like MIT) I'm missing. [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 23:03, 7 October 2024 (UTC)
:On their own, few of them are intrinsically bad, in the right context.
:*"Please, buy" - valid comma. Prefixed subclause (general plea).
:*"Please buy, apples" - valid comma (more specific plea).
:*"apples, mac" - valid comma (list-type).
:*"mac, and" - valid comma (potentially a conjunctive sub-clause).
:*"mac and, cheese" - valid comma (potentially a post-conjunctive sub-clause).
:*"and cheese, milk" - valid comma (follow-up sub-clause).
:*"cheese, milk, and" - Oxford comma. (Thus invalid, by default. IMO.)
:*"milk and, bread." - ...would be valid, as above, except for the sentence ending.
:*"and bread,." - Ok. Definitely the worst. (Except for the Oxford Comma, which is still worserer!)
:Obviously, combinations of them (or counterpart lack of them, in some cases) can clash badly. Some can work well together, but using ()s, ;s or feetnete* is often better than diving in and out of sub-clauses in the midst of a comma-bound list and potentially making it ambiguous whether you're diving in/out of a clarifying aside or replacing a non-terminating conjunction or perhaps one of the other usages to which a comma might apply.

::Sorry, no: "and," is bad grammar, except when illustrating a dramatic (but grammatically wrong) verbal pause; ", and" is fine for noting a pause used to divide a list, but it's best to use semicolons in a divided list. IE: "milk; bread; mac and cheese; blood, sweat, and tears". (Again, "blood, sweat and tears", would be atypical cadence if spoken aloud; therefore, the comma.) I don't care what style guides say, only what works well.

:::What's grammatically wrong about something like "I drink beer and, on occasion, cider"?
:::Also, the cadence of "blood, sweat and tears" has nothing to do with the commas you give it. This isn't a case of marking verbal ticks, with... uh... transcribed notation. Either for official recording purposes or in the pre-scripting of speech for later performance. One is free to nuance the phrase how you want, with or without OC. The main issue about the OC is whether a list (of ''more'' than two items) should have each (non-final) element followed by a comma? Or are commas placeholders only for the "and"/"or"s that are omited? (And my opinion is that it is the latter, all else being equal. I apply that to semicolon-separated lists, insofar as I won't end with "...; penultimate item; '''and'' last item", but prefer to omit the '''and''' (or '''or'' ), casting whether it's a list of options or an accumulation by the introductory/follow-up contextualisation of that list.)
:::But, whichever standard you prefer, there will be cases where it reads wrongly to others. If you're lucky enough to spot it, then you can look to what you can do to adjust the sentence to remove ambiguity. This does not normally mean adding in any old commas where,,,,, you think a Pinter Pause is needed. (Maybe an ellipsis, in normal writing.) The fact that a grammatical comma may be where a spoken pause may crop up is not because the comma causes the pause. The verbal pause is (if not garbled out) caused by the same understanding of how clauses/etc require intoning under the circumstances.
:::But it is a rhetorical choice as to whether to intone "blood..., sweat... and tears" or "blood, sweat and... tears" or any number of other pausing strategies, as it is how you faithfully transcribe what has already been intoned. When merely listing these in text, your chosen style of grammar is the master. [[Special:Contributions/172.70.160.134|172.70.160.134]] 19:44, 9 October 2024 (UTC)

I thought the UCLA & Michigan commas referred to quotes within citations. This isn't uncommon in literary studies, where you quote articles quoting books. Depending on your quotation style, this can result in a long string of 3-4 "commas" (as in: short lines in punctuation marks). If you place the quote between actual commas, make that 4-5.

I think the tirade against the Oxford comma in the article is not relevant for understanding the comic. "'To my mother, Ayn Rand and God' does not" is not saying that Ayn Rand is the mother. To express that one should write "To my mother, Ayn Rand, and to God". Thus the ambiguity can be resolved. I believe one of the editors is mixing in their personal taste here. --[[Special:Contributions/172.71.160.71|172.71.160.71]] 09:03, 8 October 2024 (UTC)
:Tirade? Hardly. It explains when it doesn't help (and when it might).
:And I think you misread. "'To my mother, Ayn Rand and God' does not" indeed does not say that Ayn Rand is the mother. In fact it ''explicitly'' says that "'To my mother, Ayn Rand and God'"... erm... does ''not'' say the thing that 'To my mother, Ayn Rand, and God' ''potentially'' does. (See table below.)
:The choice of how to disambiguate "my mother, who is Ayn Rand", as a concept, is another thing and has multiple options. Disambiguating in the direction of a simple list is the contention surrounding the Oxford(/Serial) Comma itself (it is, by definition, being used in the list format), given that some circumstances are most helped by it and others are most helped by its absence. If you're strongly for the OC, you'll hopefully rewrite problematic OCed formulations so that you can use it. If you're strongly against it you should change problamatic non-OCed versions so that you can better go without one. [[Special:Contributions/172.70.85.128|172.70.85.128]] 10:21, 8 October 2024 (UTC)

I didn't think it was considered schwa when stressed as in "up" and "love". But my dictionary has a schwa in its pronunciation guide for both, so I guess I was wrong.

:Some dialects split the vowel at the end of "comma" from the vowel in "strut," but most North American dialects don't.

In vowels that split comma and strut, schwa is rarely stressed, but that's not a rule.

1494: Insurance

2024-02-28T17:13:23Z

IMSoP: /* Explanation */ I don't think it's necessary to *alternate* between those two scams; either *alternative* would be enough

{{comic
| number = 1494
| date = March 4, 2015
| title = Insurance
| image = insurance.png
| titletext = LIFEHACKS: You can just take all the luggage off the airport conveyer belt and leave with it. They don't check that it's yours at the door!
}}

==Explanation==
[[Cueball]], apparently having just purchased a new insurance policy, is given a document explaining the policy terms. As is often the case, he's presented as some sort of programmer or at least logically minded person. He reads through the terms that are handed to him, and finds some sort of loophole. This is a play on the fact that programmers tend to look for loopholes in programs, code and system architecture, and treat finding them as a challenge (either to exploit them, or to prevent such exploitation by other parties). The fact that Cueball is trying to discuss his findings with the agent suggests that he's trying to prevent it from happening, rather than planning to do it himself.

In this case, the obvious "loophole" in a fire insurance policy is that the customer generally receives a large payment in the event of a fire. This means that a person could make money by insuring a building or other property for more than its actual value, then deliberately setting a fire. Alternatively, someone could set a fire and claim that more valuables were destroyed than actually were. In either case, the customer would effectively receive free money for their troubles. In principle, this could be done repeatedly, resulting in an unlimited source of money.

All of this is implied simply by Cueball reviewing the document, starting to ask a question, and being cut off by the agent, explaining that this {{w|Life hacking|"cool hack"}} is actually just an instance of {{w|insurance fraud}}, which is a) well known and b) highly illegal. In practice, insurance companies are constantly on the lookout for such forms of fraud, and attempting to do so in real life would be more likely to land you in prison than to enrich you.

The comparison here is that exploiting a program's faults can be regarded as interesting or fun, while exploiting the faults in a legal document will often result in some sort of legal repercussions. Moreover, most such exploitations that involve money have usually been figured out already, and systems changed or laws passed in order prevent them from happening. When they do occur, the exploiter is subject to legal punishment.

Cueball begins to ask how the agent knew what his question was, and is again cut off by the agent explaining that he sees a lot of programmers, suggesting that Cueball is not the first to consider that particular loophole.

The title text provides another example: US airports typically place passengers' luggage on carousels, and leave it to the individual travelers to find and retrieve their own luggage, which would seem to make it easy to take luggage that's not yours (even "all the luggage"), but that's less of a 'hack' than a crude form of petty theft, which contravenes both the law and normal social and ethical expectations.

It should be noted that there are place in which it's typical for airports to verify luggage ownership before allowing people to take their bags. In most wealthy countries, this practice has largely been abandoned, because other peoples' luggage isn't typically very valuable, airports are generally fully of security cameras, and walking off with a random piece of luggage creates a significant risk that the actual owner will see you trying to take it. For these reasons, the risks associated with such theft generally outweigh the rewards. A single person trying to remove "all the luggage" would be particularly impractical. Even if they could contrive a method to transport it all, their actions would be so obvious that they would almost certainly be caught immediately.

The core point, in both of these cases, is that theoretical loopholes, which might be easy to exploit in computer code, are usually wildly impractical in reality, and often carry both moral implications and the risk of punishment.

[[1469: UV]] also contains a case of insurance fraud.

The term hacking in IT is ambiguous and goes from code development (in particular in the opensource community) to the fact of "using a {{w|Hack|hack}}". A hack would then refer to a tricky piece of code doing the intended job in a way that the framework or project in which it is inserted was not intended to. To the general public, 'hacking' a system would normally refer to some illegal way of achieving a goal against the will of the original developers of the system, like getting a copy of all the data available or taking advantage of some unwanted behavior, but a more distinctive term for such an exploitation (maliciously or after an invitation to perform legitimate penetration testing) would be 'cracking'.

This comic is making fun of what IT hacks would look like in real world. Surely, taking lots of luggage from an airport is technically possible and probably not so difficult, but first, it looks weird, and second, it's also obviously illegal. The weirdness of such behavior is more obvious in real life than in IT.

It is worth noting that it is currently popular on social media sites to share small tricks to make one's life easier. This is called {{w|Life hacking|"life hacking", or "hacking your life"}}.

2886: Fast Radio Bursts

2024-01-27T14:42:43Z

IMSoP: /* Explanation */

{{comic
| number = 2886
| date = January 26, 2024
| title = Fast Radio Bursts
| image = fast_radio_bursts_2x.png
| imagesize = 469x524px
| noexpand = true
| titletext = Dr. Petroff has also shown that the Higgs boson signal was actually sparks from someone microwaving grapes, the EHT black hole photo was a frozen bagel someone left in too long, and the LIGO detection was just someone slamming the microwave door too hard.

==Explanation==
{{incomplete|Created by an ENERGETIC OVEN-SIZED STAR - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

[[Cueball]] is at a convention, stating the different sources of {{w|fast radio burst}}s, which are short high-energy signals which have been detected by astronomers, but whose source is not known. His team is pretty sure that most of these bursts are energetic stellar objects in space - that is, astronomical phenomena.

He then says that some of them are caused by {{w|microwave oven}}s, citing Dr. Emily Petroff's work on identifying the apparent source of "{{w|Peryton (astronomy)|peryton}}s" at the {{w|Parkes Observatory}}.<ref>E.Petroff et al. (2015). "[https://academic.oup.com/mnras/article/451/4/3933/1119649?login=false Identifying the source of perytons at the Parkes radio telescope]". ''Monthly Notices of the Royal Astronomical Society'', '''451'''(4):3933–3940.</ref> These are signals similar to fat radio bursts, but which originate on Earth and not in space; initial hypotheses included atmospheric effects related to {{w|lightning}}, and passing aircraft, but they were eventually identified as a much closer range signal from microwaves escaping as the oven door was opened inside the observatory.

After that, he explores two further options, combining attributes of the previous two:

* Energetic stellar-sized microwave ovens; this is unlikely since microwaves typically are not stellar-sized and they do not float in space{{Citation needed}}
* An energetic stellar-sized object in the break room, which would be surprising, as we have yet to see a break room being able to contain an energetic stellar-sized object. Although unlikely, he says he is sending a grad student there to double-check. Presumably the student is being sent rather than Cueball himself both because it is unlikely to give useful data, and because if there is indeed energetic stellar plasma in the break room, the million-degree temperatures would probably kill anyone who enters it.

The title text references a number of other discoveries, and suggests explanations based on microwave ovens for each of them:

* The apparent detection of the {{w|Higgs boson}} at the Large Hadron Collider was actually someone [https://www.youtube.com/watch?v=wCrtk-pyP0I&t=1s microwaving grapes], which generates plasma
* The [https://science.nasa.gov/resource/first-image-of-a-black-hole/ image of a black hole] captured by the Event Horizon Telescope was actually a burning bagel (a notably ring-shaped bread product)
* {{w|LIGO}} (the Laser Interferometer Gravitational-Wave Observatory) did not detect gravitational waves, but was instead disturbed by someone slamming the microwave too hard

In each case, these are highly improbable - for instance, LIGO used a complex suspension system, and two sites (one in Louisiana and one in Washington State) comparing signals, to rule out such interference.

See [[2289: Scenario 4]] for a similar situation.

So... discussion about "Hot Water Heater" vs. "Regular Water Heater"... I was assuming this was a joke regarding the redundancy of the term "Hot Water Heater" since "Water Heater" is already making the water hot, so why would you need to heat water that's already hot? Similar to RAS Syndrome, I thought Randall was making fun of that, but the explanation has a different idea... which... kind of makes sense? But... I've never seen anything like what is being described. [[User:AdmiralMemo|Admiral Memo]] ([[User talk:AdmiralMemo|talk]]) 05:22, 31 October 2023 (UTC)

Regarding the "one surprise mystery outlet", I don't think it's necessary to assume it was wired that way by mistake. When extending the wiring in an existing house, it's not always easy to wire up an extra breaker, or use the most logically labelled one, and there may not be a compelling safety reason to do so. For instance, in my parents house, the original sockets are all wired from the floor, and when an extra one was needed for a boiler control, it was easier to run a conduit ''down'' from the floor above; so that particular socket is on the [https://en.wikipedia.org/wiki/Ring_circuit ring] marked "Upstairs Sockets" on the consumer unit. - [[User:IMSoP|IMSoP]] ([[User talk:IMSoP|talk]]) 09:18, 31 October 2023 (UTC)

2822: *@gmail.com

2023-09-01T10:00:29Z

IMSoP: there's nothing in the comic about expanding the list in the body; possibly just a misunderstanding of the jargon "loop in"

{{comic
| number = 2822
| date = August 30, 2023
| title = *@gmail.com
| image = gmail_com_2x.png
| imagesize = 305x269px
| noexpand = true
| titletext = Hi all, just replying to loop in *@outlook.com and *@yahoo.com.
}}

==Explanation==
{{incomplete|Created by BOT@COMPUSERVE.NET - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

When performing operations on computer files using a command prompt, the asterisk (*) may be used to represent a collection of items whose names match a particular format. For example, "*.txt" denotes all files whose names end in ".txt". This is called a wildcard. Similarly, the e-mail address *@gmail.com, as illustrated in the comic, is a proposed feature from Randall that would send an email to ''every'' {{w|Gmail}} user, without having each and every valid Gmail address at hand (of which there are about 1.8 billion). For obvious reasons, this is not actually a feature, but Randall suggests that if Google ever wanted to shut Gmail down, they could do either do it this way (possibly causing a service-ending overload of resources) ''or'' allow someone this one last boon (as a farewell gift, knowing that there would be relatively few additional repercussions to deal with). Google does not seem particularly likely to shut down Gmail, as it is a source of information for their advertising and other businesses, but they are known for [https://killedbygoogle.com/ abandoning programs and projects] even after they have been found useful (by at least some people) for years.

Reply-all is a sometimes useful feature of email that nonetheless commonly causes headaches and annoyances for both users and administrators. By allowing users to simply reply to everyone copied on the email, it encourages users to do this rather than think carefully about which people their response should be addressed to. This causes lots of users to receive irrelevant emails, and email servers to have to process and store a lot of unnecessary data. Randall's email is essentially designed to induce every Gmail user to email every other Gmail user, generating an excessively large number of emails.

A recurring phenomenon for email users, especially in the early Internet days of the 1990s and 2000s, was a reply all storm – someone would start a message to a very large group, perhaps hundreds, and even if only 5% of recipients replied to say something like “take me off this list“, a storm of dozens of replies would soon follow. Inevitably, new replies to everyone would start saying things like, “stop Replying All!” If this were done with millions of Gmail users instead of just dozens or hundreds, their result would be apocalyptic. A real-life example was [https://www.wired.co.uk/article/nhs-email-reply-all-down a 2016 incident involving 1.2 million staff at the UK National Health Service].

In reality, the asterisk wildcard is not generally usable via email servers, although email ''clients'' may sometimes implement such a function, internally, perhaps to support mailing-list functions (though more commonly this is done via named address-book 'groups'). That said, the asterisk ''character'' is a valid one that may form part of the name of a mailbox, including group-boxes that might facilitate server-side distribution.

The title text suggests a reply where someone decides that all users of {{w|Outlook.com}} (formerly Hotmail) and {{w|Yahoo! Mail}}, two further well-known mail services with similarly large user bases, should also be included - "loop in" is common business jargon for [https://en.wiktionary.org/wiki/loop_in#English meaning "include in communication about something"], related to "being in the loop" meaning "being informed and up to date". This also alludes to an occurrence in email chains where a user replies to simply add another user into the chain, which doesn't add much information to the group.

The number of this comic (2822) is the same as the number of [https://datatracker.ietf.org/doc/html/rfc2822 RFC 2822], which is the 2001 version of the email specification (it was replaced in 2008 by RFC 5322).

Add to this the unfortunate tendency to promote Top-Posting (I'm looking at you, Outlook Express, but the various successors and competitors over the last three decades need not have followed that most unconventional convention too!) and 'email chains' of nested replies so easily build up in volumes that never would if each sender were encouraged to actually read through the prior chain of messaging (perhaps realise their contribution was unnecessary, given what someone already else said two iterations ago!) and judiciously prune out the historic ">>>>..."ed contributions that they aren't replying to. It also lets you mid-post (respond to a paragraph/point immediately after that embedded paragraph/point, to skip and excising later points intelligently) and stops it from becoming a hige hidden upside-down tree of ''everything'' in that message's history. (Which can also be a different problem... Something might have been said early on that might be best not to repeat to a later "copied in" contributor, for security or even politeness reasons, but now it's there to be discovered.) But, instead, the modern solution is to hide these top-post tree-roots behind client-side "collapsed"-content and keep forwarding all historic context ''unless'' someone takes time to scroll down-down-down from their "Yeah, I agree" simple response and snip the "..."-worthy stuff out (as well as many, many repetitions of "Please don't print this email out if you don't have to", "This email is intended only for the stated recipients", "The views of this sender do not necessarily reflect the views of his company", etc, often adding up and combining into .sig additions much larger than their respective senders' contributions). Plus an often confusing attempt to "threadify" multiple received messages, which (done right) would actually do better than the retention of a full and unexpurgated reply tree within Every. Single. Individual. Email! ...can you tell that I've been annoyed about this for pretty much almost thirty years? And it really hasn't been made any better over the last decade or so.

2023-08-03T10:03:13Z

IMSoP:

I don't actually know what name of 'coiling' it has, but the way I was taught to coil an AV cable (by an AV technician), and these days mostly use with long (garden-mower) power extensions, was ''maybe'' the 'quarter-turn' - though it's not a quarter, so maybe not - in finger-rotating the latest "end of loop" around the axis of the cable to leave it effectively twistless in its looped form (whilst introducing a 'one twist per loop-so-far' longitudinal twist in the still trailing unlooped cable that easily 'rolls-out' as you progress towards the free end/drag the length towards you). Done right, it's like smoothly 'drum-winding' the cable. But you ''can'' over-/under-twist the cable (especially if it has an internal/inherent twisting, like those christmas lights probably have with probably two entwined single-cores) so you may need to keep an eye on the multiloop you're forming and backtrack a bit if it looks like it's starting to figure-of-eight from the combined helical forces. But tricky to get perfect, may have a bit of a loop-twist (that only stays untangled due to it being ultimately hung on a hook). Maybe I've just not been taught the right methods by a powercord expert. [[Special:Contributions/172.70.90.20|172.70.90.20]] 19:39, 2 August 2023 (UTC)

: That first method is pretty much how I was taught by a guy with rather expensive microphone cables. It really does help the cable to last longer, since it's not stored with a twist. As a bonus, coiling a rope or extension cord this way also lets you throw it without it tangling in midair. Just make sure to hold onto/step on the non-thrown end...

Another profession that deals with hose/cable managment is nursing (e.g. in operating room). Don't know if they have any techniques distinct from those in the mentioned professions. [[Special:Contributions/172.69.135.82|172.69.135.82]] 21:50, 2 August 2023 (UTC)

As a sailor once explained to me, the AV method (over/under) can potentially form a clove hitch around one's ankle while on deck, hence their use of figure-8. Meanwhile, there's another technique espoused by the likes of 'Essential Craftsman' where you basically use a chain stitch to hold it all together.

This sentence makes absolutely no sense to me:

: ''... alternating each obvious helix loop with a backhand loop (backwards helix turn) where the loop curls the same way as the other loops, but its 'helix height' is backwards ...''

I think I need an "Explain Explain xkcd"... 😕 [[User:IMSoP|IMSoP]] ([[User talk:IMSoP|talk]]) 10:03, 3 August 2023 (UTC)

:: My reading of it is that Beret Guy does strange things because he doesn't truly understand how things work (the way that scientific consensus understands, c.f. Vacuum Energy). This geologist is doing a strange thing because he is ''just so good'' at the regular science he knows. Success through hypercompetancy, not hypernaïvity, in modulating pressure-waves (like a phased-array transmitter?) from the four chair-leg points sent through ''theoretically'' knowable layers of floor and bedrock.
:: It's a stretch, but given the changes needed to put Beret Guy into protagonist position (it'd be just "don't ask this guy...", not a geologist) then I think it's a perfectly valid compositional choice on behalf of Randall. (Who can do as he likes, without my trying to be apologist for him, but I'll explain my conclusions anyway.) [[Special:Contributions/172.71.178.64|172.71.178.64]] 10:28, 21 March 2023 (UTC)

The text mentions the UK Salt reserve, used to prevent black ice on roads. I assume that US states that get sufficient snowfall also maintain reserves of salt and grit to keep their roads open. Or does it simply get too cold for ice to be of any use? {{unsigned|Arachrah}}
: Yes, states and municipalities in the US definitely maintain reserves of salt for use in treating roads during winter weather. Such reserves are commonly stored in dome-shaped structures (often seen near highway interchanges), which I assume is part of the allusion in the title text. I don't believe this statement in the current explanation is completely accurate: "Ordinary salt is also available in abundance throughout the U.S. so there is no need for any kind of salt reserves, strategic or otherwise." This may be true at a Federal level, but having grown up in the northeastern U.S., I recall hearing of some of the smaller municipalities running low on/out of salt during especially harsh winters.

IMSoP: yeah, I've gone ahead and deleted that

Interesting, I wrote a basic description since the page was blank, and apparently, within the time I was writing someone else posted an explanation so mine wasn't saved. It's interesting that that's how the site deals with things like that. In this case, the explanation the other guy wrote is better so it's fine, but what if you wrote something super long and detailed and it vanished because someone else was editing at the same time? It didn't appear in the version history so it's not like I could go back and retrieve the text. Again, it doesn't matter here but it's interesting to think about.

So soccer balls appear in the very tiny ({{w|Fullerenes}}) and the very large, as noted here.

Just to note (in case anyone wonders why one particular edit, in passing) that the only SI length unit is the metre (and, yes, with the French-inspired '-re' ending in all 'English' nations ''except'' the US, who don't even want to use it so can't complain (/jk!)). Millimetres, centimetres, kilometres, etc are only present in the broader 'decimalised' metric system using the SI-prefixes. Just as the litre (ditto on spelling!) is not SI, but also is not SI-unit in size, being 1000 of the SI-derived baseline 'cubic centimetres' (each also being 1 millilitre), rather than anything as logical as being 1 whole cubic decimetre or awkward as a "milli-(cubic metre)".

'' //However, BSBIT also stands for Bachelor of Science in Business Information Technology [2], a relatively new specialization where business majors learn programming techniques [3], so the acronym could also have been used to imply that a graduate of this major came up with the soccer ball model listed in the presentation.//''

No. No, it could not have be used to mean that, because that's '''completely absurd.''' Does ''anyone'' here ''actually'' think that BSBIT was intended this way? Even if you were the person who ''invented'' the "Bachelor of Science in Business Information Technology," I guarantee you would not have interpreted Randall to have been using this particular abbreviation in this incredibly contrived and obscure way. As far as I'm concerned, it is 100% certain that "BSBIT" refers to "Big Soccer Ball In There" and absolutely nothing else. The idea that we need to find alternate interpretations of everything, no matter how unlikely it is that ''anyone'' will see them that way, and present them as equally plausible as what ''everyone knows'' is the intended interpretation, is getting ridiculous.
My guess is that someone plugged "BSBIT" into an acronym finder, found this particular acronym, and decided to put it in - possibly thinking it was actually helpful, or possibly just for grins.
And sure, maybe we can have something in a separate "trivia" section, but in my view, it's just silly to put it in the main explanation. mezimm [[Special:Contributions/172.69.71.61|172.69.71.61]] 20:13, 10 September 2021 (UTC)

:Agreed, the whole thing was a long and unnecessary digression - the joke Randall is making has nothing to do with the (rapidly declining) use of "Imperial" units in the UK, and everything to do with the (very much current) use of "customary" units in the US.

==Explanation==
{{incomplete|Created by CUEBALL'S POLAR HEXAGON - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
{{w|Saturn's Hexagon}} is a cloud formation on Saturn centered on its north pole. Similar to Jupiter's {{w|Great Red Spot}}, Saturn's Hexagon has proven a persistent feature observed by multiple space probes. The cause was not known until recently, when data from the 2006-2009 {{w|Cassini–Huygens}} probe could be analyzed in depth. This finding was widely publicized in popular science media (see for example [https://www.sciencealert.com/astronomers-think-they-figured-out-how-saturn-s-giant-hexagonal-storm-could-have-formed]) and is related to how currents flow deep within Saturn's atmosphere.

Randall proposes an alternate explanation: it is the top of a {{w|Ball_(association_football)|soccer ball}}. Soccer balls are made in the shape of a {{w|truncated icosahedron}}, where faces alternate between regular hexagons and regular pentagons to achieve a more uniform roll. This design was introduced in 1968 as the {{w|Adidas Telstar}}, and is now considered the "traditional" soccer ball. The article is shown to refer to this as the "BSBIT model", a technical-sounding acronym from "Big Soccer Ball In There".

"Soccer" is the name used in the United States for {{w|association football}}, a game called simply "football" in much of the world. Similarly, the US makes wide use of {{w|United States customary units|customary units of measurement}} (inches, feet, miles, pounds, etc.) where much of the world uses the SI or metric system (centimetres, metres, kilometres, kilograms, etc.), so "football" is jokingly referred to in the title text as the SI name for "soccer". As much of the Web panders to a significantly US-based audience{{fact}}, many sites use only American customary measurements and omit metric equivalents, which might annoy non-US users; Randall parodies this by sarcastically and non-seriously apologizing.{{fact}}. Just as the American customary units derive from British {{w|Imperial units}}, the term "soccer" originated in the UK, originally to {{w|Names_for_association_football#Background|distinguish it}} from rugby football (sometimes "rugger"), before soccer became the most common form of football there.

This comic may also reference something often quoted to students decades ago that Saturn [https://solarsystem.nasa.gov/planets/saturn/in-depth/#:~:text=Structure-,Structure,by%20intense%20pressure%20and%20heat. would float] if there were a large enough pool of water to hold it, often having been stated as "Saturn is a giant beach ball". This refers to the property that Saturn is the planet with the {{w|Saturn#Physical_characteristics|lowest average density}}. This, of course, is a lot more [https://www.wired.com/2013/07/no-saturn-wouldnt-float-in-water/ complicated] in reality.

Incidentally, the presentation of the truncated-icosahedral 'football', pressing one clear polygonal face up along the upper limit of the planetary sphere, has much in common with the (non-truncated) icosahedron that floats within a {{w|Magic 8-Ball}}, arranged to display just one random triangular face whenever its viewing window is upwards. This may be coincidence, without any obvious attempt to directly reference any of the [https://knowyourmeme.com/photos/1404098-safely-endangered popular memes] relating to this. Randall has previously parodied the magic 8-ball in [[1525: Emojic 8 Ball]].

This is the fourth installment in the series of [[:Category:Cursed Connectors|Cursed Connectors]] and presents Cursed Connectors #280: USB-C to UV-C. It follows [[2503: Memo Spike Connector]] (#102).

The comic depicts a cable with a USB-C connector on one end and a UV-C LED on the other.

USB-C is a type of USB connector which supports many different types of data. UV-C is a type of Ultraviolet light.

This comic depicts a cable that converts from USB-C (at the top of the picture) to UV-C (at the bottom).

{{w|USB-C}} is a rotationally symmetrical {{w|Universal Serial Bus}} connector.

[https://en.wikipedia.org/wiki/Ultraviolet#UVC UV-C] is a range of ultraviolet light with wavelengths between 100 and 280 nm. This is often used as a germicide, so this comic may also be related to the COVID-19 pandemic.

The title text mentions that UV-C is unpolarized. This mirrors the fact that USB-C is symmetrical. So neither of them requires you to get the orientation right when using it.
