| − | ::Well, to be exact it makes Megan 37 years, 13 days, 12 hours, 7 minutes, 13.3 seconds old (rounded to the nearest tenth of a second). This is based on 900/24.3 = 37.0370 (...) That would make her born on July 6, 1982 (if we work back from the date of publication of the comic). But to be realistic I guess she was probably rounding the score to the nearest decimal, rather than writing 24.32432... (i.e. 900/37), in which case I'm wrong. Either way, spurious accuracy is fun!!

| − | : I think it's pretty clear that the title text varies from comic to comic. Sometimes it's clearly a character's voice. Sometimes it makes more sense as a narrator's voice. Sometimes it's clearly talking about Randall's life. I realize that this site tends to attribute the title text to Randall's voice, but personally, I consider it an unattributed voice. Sometimes it's him, sometimes it's more of a narrator or character voice. Similarly, the actions in the comics are sometimes clearly influenced by events in Randall's life, but they're also clearly not other times. If it turned out that he made Megan 37 because his wife is 37, that wouldn't surprise me, but neither would it surprise me if he did something different, because he does that on a regular basis. (In other words, without additional evidence or supporting information, I think it's weird to state as a fact that the traits of various characters are, in fact, traits of Randall and his friends and family.)

| | Propane tanks do not "expire", that is they do not go bad with time, and you do not need to throw them out after the date. The date on these tanks is when they need to be inspected for damage, as mandated by Federal and state laws. If the tank passes inspection a new date in put on and you can keep using the tank (propane suppliers can legally keep refilling it.)

| | There is one caveat to Megan's strategy: since the fraction (year you found item - year item expired)/(your age when you found it) converges to one as time goes on regardless whether the numerator is bigger than the denominator, as long as the item expired before the year of your birth, postponing the discovery reduces your score (considerably). | | There is one caveat to Megan's strategy: since the fraction (year you found item - year item expired)/(your age when you found it) converges to one as time goes on regardless whether the numerator is bigger than the denominator, as long as the item expired before the year of your birth, postponing the discovery reduces your score (considerably). |

| − | Her mom's pickles could still have had an expiration date before 1978 - according to [https://www.smithsonianmag.com/smart-news/sell-and-best-dates-food-are-basically-made-hard-get-rid-180950304/ this article] they were around in the 1950s and on store shelves by 1970.

| − | :Perishable foods had expiration dates in the 1970s at least (maybe earlier in some countries and some stores). But non-perishable foods did NOT had dates until the 2000's or later. A home canned jar of pickles could have a hand written date, but this would be the date it was canned, not an expiration date. Because anyone in the 1970s who knew how to can would know if they did it right the food would not go bad. If they did the canning wrong they would not need a expiration date to know this, they would know in a few weeks, by looking through the mason jar at the food inside. Or by looking at the food and glass spread around the pantry after the jar exploded. So Megan's mom could have a loaf of bread with a 1978 date, but not a jar of pickles.

| | :To be fair, many items are labelled "Best Before" or "Sell By" - implying that the food item will be edible for at least some time beyond that date. Actual expiration dates on preserved food items do seem to be rarer. There are cases of canned food items from the early 1900's still being in good shape after 100+ years - and those would not have had any expiration date. But one issue is that back then, cans were made by soldering sheets of tin together - and the lead in the solder slowly leaches into the food making it unsafe to eat even though the food itself seems well-preserved.

| − | I think the point that needs to be made in the explanation is both the items in the comic (a can of beans and a jar of pickles) do not go bad with time but in fact remain edible indefinitely.
| |
| − |
| |
| − | Food going bad, in the sense that it will make you sick if you eat it, is most often caused by harmful bacteria growing in the food. Less often caused by fungi or yeast growing in the food and creating a poisonous substance, like methanol (wood alcohol.) The process of canning food involves boiling it to kill all possible pathogens, then sealing it in a can/jar while the food is still hot, with no air bubble. As long as this process is done correctly, as long as the jar lid has an air tight seal, and as long at the can is not punctured or gets a hole rusted through, no bacteria/virus/yeast/fungi can get in and the food can not spoil. Some food may discolor over time in the jar/can, or the texture may change, but it can not go bad in a way that makes it unsafe to eat.
| |
| − |
| |
| − | If the canning process is done incorrectly and bacteria/fungi/yeast is sealed in the can/jar, the food goes bad in a few weeks, not years. Gases given off by the decomposition process often cause the can to swell, or the normal concave jar lid to bulge upwards. Sometimes the internal gas pressure is enough to burst the can/jar, as used to happen to people who canned at home using mason jars. If it does not burst, you are still going the know the food has gone bad the minute you open the can/jar, even without looking inside.

| − | == "i don't know how to do links where it says one thing and goes to another, can someone fix that?" ==
| |
| − | | |
| − | To the IP editor who put in that edit comment, here's the longer explanation, in case you come back and see this... There are three basic link-types to consider:
| |
| − | *Internal to ExplainXKCD - use double-square brackets for links, with or without the underlines for spaces of the URL, e.g. <nowiki>[[Title of page]] or [[Title_of_page]]</nowiki>, and that will give the link under the same text. To change what it says, insert a pipe/bar and the alternate text in before the closure, e.g. <nowiki>[[2178: Expiration Date High Score|this comic]]</nowiki> should point to [[2178: Expiration Date High Score|this comic]], though general convention is to just have the "Number: Title" version bare and in context, as "this/that comic" or whatever is a bit terse.
| |
| − | **It works for all proper pages, not just comic-numbered ones, like [[Cueball]], although a link to a <nowiki>[[Category:Some category]]</nowiki> would just invisibly add that Category to the page (best done after the Talk-insert markup) and if you want to add a category index page as an inline clickable link, use a preceding colon <nowiki>[[:Category:Some category]]</nowiki> or <nowiki>[[:Category:Some category|this text links to the Category index]]</nowiki>, such as [[:Category:Comics featuring Black Hat|Comics featuring Black Hat]]. That's a commonish issue, I find.
| |
| − | *Interwiki links - double-curly brackets to activate the template that has been set up (if one has) to properly format the link to the alternate site's page. <nowiki>{{w|Wikipage title}} or {{w|Wikipage title|link text}}</nowiki>, for example. Start with "w|" for Wikipedia, "wiktionary|" for, well, Wiktionary, and (though it's a different family of resource) someone set up "tvtropes|" for ease of use. That last one renders slightly different, perhaps as a warning not to get sucked into a Wikiwalk if you decide to wander into it... ;). But, in general, it makes interwiki links as inobtrusive as internal linking, e.g. {{w|Wikipedia|this one to Wikipedia's page on Wikipedia}}...
| |
| − | *All other links - Single-square bracketting <nowiki>[http://your.url.here/in/full]</nowiki>, which renders as a 'note-link' that isn't very nice (there are ref-based ways of properly footnoting, usually no need for that though). To give it alternate text, add within the []s a ''space'' and the display-text you want. Bare URLs (if interpretable) get rendered as literal-links with display text. Examples: Note[http://www.microsoft.com] or with [http://www.microsoft.com alternate text] or literally just http://www.microsoft.com on its own.
| |
| − | There are other useful things (e.g. literal wikilinks with an 's' appended after any {{}}s gives links to the inner literal pages but rendered as {{w|plural}}s, and the uppercased first-letter of a page title can be lowercase (but sometimes it's too complicated to rely on that). But best practice is to use [[]]-links if possible, fall back to {{}}-links if that's necessary (and you know that the template name you need exists) and only go the full [url] route if you have to.<br />
| |
| − | I'm sure there's better guides on how to do this (no errors, no missing info) in the site's help-pages or on general external mediawiki resources, but as the editor who prompted this info hadn't found it (and I had to work much of this out on my own, from seeing what others had done correctly/incorrectly over a number of years) I thought it worthwhile to give this 'summary', hopefully not too wrong in substance...
