Some of the examples of "incorrect" moons are kinda questionable - like, how relevant is the position of the moon when there's literally a giant divine skyperson standing on it, grabbing stars and scattering of them?

: Randall uncharacteristically missed an opportunity for pointing out additional errors that people make: It's interesting to note that you can get a decent estimate of the artist's latitude by looking at how they draw a crescent moon. In equatorial cultures, the crescent looks like a cup or a boat - and they interpret it like that. But if you look at most english language children's books, the crescent looks like a letter 'C' or a 'D' with a human face - suggesting that they were probably made in the tradition of northern Europe. When I first moved from the UK (more or less a 'C'-shaped crescent moon) to the southern USA (more like Randall's depiction of the correctly-drawn crescent with the points at a roughly 45 degree angle to the horizon) - I subconsciously felt that the moon "looked wrong" - it was only much later that I understood the reason.<br />
<br />
: Furthermore, this rotation of the moon relative to the observer also explains why "The man in the moon" is a common trope caused by the pareidolia interpretation of the cratering patterns of the moon in northern cultures. But in southern cultures, people tend to see a rabbit in those full-moon patterns - and that has become the source of many of their stories. In Japan, for example, the patterns are interpreted as a rabbit making mochi (a sort of dense dumpling made from rice pounded into a powder) on the moon - the Sea of Tranquillity forming the head, and the Sea of Clouds forming part of the pestle in which the rabbit is pounding the rice.<br />
<br />
: Now that I'm more acutely aware of this - it's interesting to note how many movies get the orientation of the moon wrong for the location that their story is supposedly set in! [[User:SteveBaker|SteveBaker]] ([[User talk:SteveBaker|talk]]) 13:41, 26 September 2016 (UTC)<br />

: Not quite sure how to add this but Gibbon is the author of The Decline and Fall of the Roman Empire - or a type of Ape. It is not a phase of the moon. Also I think the moon depicted is Waning. [[Special:Contributions/141.101.98.113|141.101.98.113]] 14:02, 26 September 2016 (UTC)<br />
I think the correct expression is gibbous - "having the illuminated part greater than a semicircle and less than a circle"<br />

::: Indeed - but that's pretty much how it looks down here in sunny Texas. It's one of those things you never think about - but once the fact of it clicks in your head, you get this visceral feeling of how you're standing on a large ball rather than a flat plane! Ha!

: "Wax gibbon" is probably nothing more than a joke on mispronouncing "waxing gibbous".

The first "wrong" image is also only possible if the bright portion is presumed to be the sun during a solar eclipse, assuming the sky is actually depicted as black.

I've always wanted to create a story, and have the horns of the moon connect on the other side, so you have a blackbody in front of the moon, in parody of this tendency.<br />
Also, interesting how the moon is at different rotations in different locations. I never did see the rabbit in the moon. Now I know why.

While the comic is obviously exxaggerating, there are situations where this could make a certain amount of sense. IF you can design a server so that most or all of the components reach end-of-life at about the same time, then if a hard drive fails on one server, every other component of that server is likely to fail soon as well.<br />
<br />
If you install entire server racks or server rooms at the same time, where every machine contains components with the same basic life cycle...<br />
<br />
then in theory, once the first component fails, you can ignore it until mass component failures causes the entire rack/room to fall below a certain readiness level.<br />
<br />
At that point, there's no reason to pay a technician to spend several days removing and replacing half the individual components throughout that rack/room, when the other half are just going to fail in the next few months anyway. In theory, it might be economically more efficient just to scrap everything at once, bring in brand-new server replacements, and re-sync the needed data from a networked backup.<br />
<br />
in real life, it's very hard to build a server that will reliably degrade on schedule.... but with the right tradeoffs, and enough long-term performance data, it might eventually become possible to do so. <br />
