She would be traditionally be devious/sociopathic enough to have made the comment just now ''in order that'' Black Hat would do (something like) this.&lt;br /&gt;
:Image-wise, the figure sits somewhere between the 'reference images' of Megan's hair (right thickness, grown a bit longer here) and that of Danish (finer and more casually-longer), and there are a number of ambiguous appearances that are just a subtle change in hair away from either, so I couldn't say for sure without taking into account the dialogue/activities involved.

&lt;br /&gt;
I assumed the lava lake would be used like a sand trap, so the golfer would want to hit the ball, rather than collect it. As such, the ball would likely be coated with a material of sufficiently high combustion temperature to be able to survive (at least for a while) on the surface of the lava. The golfer would then require shoes that allow for walking on the lake, but I believe such exist. &lt;br /&gt;
My question is, how difficult would it be to hit the golf ball off of the surface of the &amp;quot;lake&amp;quot;? There would be the added challenge of a &amp;quot;divot&amp;quot; composed of some of the lava following the ball, but at least you shouldn't need to worry about &amp;quot;repairing&amp;quot; the damage? [[User:Galeindfal|Galeindfal]] ([[User talk:Galeindfal|talk]]) 15:55, 3 September 2024 (UTC)&lt;br /&gt;
: My gut feeling (awaiting the results of further testing) is that lava adhered to your ball would impede your play. Unfortunately, current USGA rules would only allow you to clean away just enough to be able to identify your ball (e.g. if your ball was entirely encased in rock, you would be allowed to chip away at the rock until you can see the ball at which point you would have to stop chipping. This means that, tactically speaking, you would want to chip away at the outside, and at the areas where you don't think the ball actually is, first to attempt to remove as much rock as possible before the ball can be seen.) You would not be allowed a full cleaning until you reached the green. &lt;br /&gt;
: One slight advantage would be that an encased rock ball would result in a lot more embedded pitches (where a ball lands with enough force to create its own divot) which would permit you to move your ball a club-length away to escape the divot. It is probable that this advantage would not be enough to offset the disadvantage of having to hit a ball encased in lava rock. &lt;br /&gt;
: The introduction of lava hazards would likely require a new section in the rulebook to cover the above issues as well as the use of rock tumblers as enhanced cleaning machines, the introduction of new club types designed to survive the rigours of lava play, permissible footwear and enhanced caddy insurance policies.

This article contains a cool photo of golfers with a huge ash cloud erupting behind them: [https://www.golfpass.com/travel-advisor/articles/lava-golf-plenty-of-u-s-courses-live-in-the-shadows-of-nearby-volcanoes] It's probably a safe distance, really, but the photo makes it look as if it was right behind them.

: Two miles (3.2 klicks) from the golf course to Halemaumau, the main vent of the Kilauea summit caldera. (pats and caresses ground) Good volcano. Nice volcano. The eruption cloud shown resulted from the draining of the lava lake that had been in Halemaumau for a decade or so, before an earthquake opened a hole in the magma chamber. The lava flowed underground down the mountain and resurfaced in the Leilani Estates housing subdivision, destroying much of it. This was 2018 (as shown in the picture caption). We were living on the Big Island at the time (in Kailua Kona, safely on the other side of Mauna Loa from the eruption). Fun times! Sorta.

&lt;hr /&gt;
&lt;div&gt;{{comic&lt;br /&gt;
| number    = 1388&lt;br /&gt;
| date      = June 30, 2014&lt;br /&gt;
| title     = Subduction License&lt;br /&gt;
| image     = subduction_license.png&lt;br /&gt;
| titletext = 'Dude, why can't you just be a normal roommate?' 'Because I'm coming TOWARD you!'&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
In {{w|structural geology}}, {{w|subduction}} is the mechanism by which one {{w|tectonic plate}} disappears under another. This process usually creates a {{w|mountain range}} on the second tectonic plate, as that starts to ride over the first and the surface geology is rucked and folded upwards. Also, water entrained in the subducting plate may rise into the second plate and provokes {{w|volcanism}}, often resulting in a {{w|volcanic arc}}.&lt;br /&gt;
&lt;br /&gt;
In this comic, [[Beret Guy]] is very happy because he has just received his ''subduction license'', which may be a play with business term ''{{w|licensed production|production license}}''. His roommate [[Cueball]] very reasonably asks him: ''Your what?'' But instead of answering him, Beret Guy begins to move towards him in their small room. It turns out that the license has literally enabled him to initiate subduction, seemingly at any point of his choosing and at anomalous speed, or else allowed him to perform an existing ability he had not previously felt he could legally use. As he slides slightly towards Cueball, he slowly sinks under the floorboards of the room, and in this process he creates a small mountain range on the floor. In the end, much to Cueball's consternation, these mountains turn his desk and chair over. Cueball physically falls out of the frame in the final panel, where Beret Guy is already halfway down beneath the floor. This would not be possible in real life.{{Citation needed}}&lt;br /&gt;
&lt;br /&gt;
The title text plays on the double meaning of the word &amp;quot;normal&amp;quot;, which Cueball means in the sense of &amp;quot;like most people, not strange,&amp;quot; but which Beret Guy interprets in the geological sense. While subduction occurs when two plates crash into each other, a {{w|normal fault}} occurs when two plates are moving away from each other. Here, &amp;quot;normal&amp;quot; is used in the sense of &amp;quot;perpendicular,&amp;quot; as the result of a normal fault is often that part of the crust moves vertically downward, forming a {{w|graben}}.&lt;br /&gt;
&lt;br /&gt;
A similarly atypical license was mentioned previously in [[410: Math Paper]]. Puns on geological terms (including types of faults) were previously made in [[1082: Geology]].&lt;br /&gt;
&lt;br /&gt;
This comic was featured in a page of [[Thing Explainer]] as part of the explanation of the ''Big flat rocks we live on''. Only the last three panels were used, probably because the words in the first panel were way too uncommon for the book - see more details [[Thing_Explainer#References_to_comics|here]].&lt;br /&gt;
&lt;br /&gt;
Subduction was again mentioned in [[1829: Geochronology]].&lt;br /&gt;

| image     = five_day_forecast.png&lt;br /&gt;
| titletext = You know what they say--if you don't like the weather here in the Solar System, just wait five billion years.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Weather forecasting}} is an extremely difficult task, even if it is only for five days. In numerical models, extremely small errors in initial values double roughly every five days for variables such as temperature and wind velocity. So most {{w|Meteorology#Meteorologists|meteorologists}} only provide us with a five-day forecast.&lt;br /&gt;
&lt;br /&gt;
In this comic [[Randall]] takes this to the extreme by first showing a '''Five-Day Forecast''' and then progressing to five-month, year, million, billion and finally trillion-year forecast, {{tvtropes|WeirdWeather|leading to weather patterns that we don't usually see on a regular basis.}}&lt;br /&gt;
&lt;br /&gt;
Since the first weather symbol is the same in all six rows, we must assume this indicates the weather today (and not tomorrow or in a trillion years). It is first in the second panel that we have made the first jump according to the label. Consequently, the last column gives the predictions for four days, four months, ...,  four trillion years from today.&lt;br /&gt;
&lt;br /&gt;
When moving past the five days, the forecast is just a qualified guess based on the time of year. In a month it is Christmas as shown in the second panel of the second row. And then it is winter with January and February so snow is likely, but certainly not something that happens on all days of a winter month.&lt;br /&gt;
&lt;br /&gt;
Looking at the five-year forecast, guesses are made as to what the weather will be like at the same time of year. For these first three predictions the weather symbols are all of the same three types. Sun, clouds and some kind of {{w|precipitation}}, rain or snow. And the temperature range from 21 to 44&amp;amp;nbsp;°F (-6.1 to 6.6&amp;amp;nbsp;°C), winter temperature.&lt;br /&gt;
&lt;br /&gt;
Then we go into the far future, jumping a million years from panel to panel. But still the weather symbols stay the same. However, in 3 million years time aliens (or advanced humans) attack with energy beams from something looking like {{w|flying saucers}}. They are gone a million years later. The temperature range is still the same (except that it rises to 52&amp;amp;nbsp;°F or 11.1&amp;amp;nbsp;°C, a possible reference to global warming) in one panel. But then while the attack is going on the temperature rises to 275&amp;amp;nbsp;°F (135&amp;amp;nbsp;°C).&lt;br /&gt;
&lt;br /&gt;
Once we get to the billion-year mark it actually becomes more meaningful to try to predict the &amp;quot;weather&amp;quot;. Because now we reach the times when the {{w|Sun}} begins to change. Although the Sun will continue to burn hydrogen for about 5 billion years yet (while in its {{w|Sun#Main sequence|main sequence|}}), it will still grow in diameter as it begins to exhaust its supply of fuel. The core will contract to increase the temperature, and the outer layer will then compensate by expanding slightly. This is what is indicated in panels two and three where the color of the Sun changes towards red as the surface becomes less hot as it expands away from the center of the Sun. The temperature will rise on Earth as indicated in the panels (105&amp;amp;nbsp;°F = 40.5&amp;amp;nbsp;°C and 371&amp;amp;nbsp;°F = 188&amp;amp;nbsp;°C). So in two billion years the temperature is hot enough that all the earth's oceans will have boiled away… Actually this will happen already in about [http://phys.org/news/2015-02-sun-wont-die-billion-years.html a billion years].&lt;br /&gt;
&lt;br /&gt;
Then once there is {{w|Sun#After core hydrogen exhaustion|no longer enough hydrogen}} the Sun will truly expand into a {{w|red giant}}. This should not happen until five billion years from now,{{Citation needed}} but in the forecast it is indicated to happen already in three. Maybe this is Randall taking liberties to show what happens during this phase, which would not fit into a five-billion-years forecast. Alternatively it is just indicating how uncertain these kinds of forecasts are, or a statement that we may not know for certain that it will take five not three billion years.&lt;br /&gt;
Disregarding this, the fourth panel shows the temperature at Earth's position inside the red giant Sun. The color of the panel indicates that we are inside the Sun. The temperature is 71,488,106 degrees Fahrenheit (39,715,597 degrees Celsius). The current temperature of the center of the Sun is &amp;quot;only&amp;quot; 27 million degrees Fahrenheit (15 million degrees Celsius). And although that may rise by a factor of ten during {{w|Stellar nucleosynthesis|helium fusion}} then that will only be at the very core and not out in the solar atmosphere reaching out to Earth Here the temperature would only be of the order of thousands of Fahrenheit, since the Sun's outer temperature decreases as it increases its diameter. So this panel's temperature also makes little sense. It may involve some ambiguities regarding what the forecast means; the edge of the red giant Sun is predicted to be somewhere near the current orbit of Earth, but the position of the Earth could change. The most likely prediction at the moment is for Earth to move outward, but if the planet is engulfed by the Sun, it would spiral inward, and at some point fall apart. So in some sense &amp;quot;here&amp;quot; for the forecast could become a position deep inside the Sun, where core temperatures could reach 100 million Kelvin.&lt;br /&gt;
&lt;br /&gt;
The red giant phase only lasts half a million years, so a billion years after the Sun has been a red giant its outer atmosphere will for sure have disappeared leaving only a {{w|white dwarf}} to cool down. Given Randall's version of this time schedule, then it will have had about a billion years to cool down, but would still likely be the brightest object in the sky as seen from where the Earth once was. It is not indicated in the last panel, where we just see other stars of the Galaxy. The temperature is down to that of the {{w|Cosmic microwave background|background radiation}}. Today this radiation has a temperature of 2.72548 kelvin = -270.4245&amp;amp;nbsp;°C = -454.7641&amp;amp;nbsp;°F. So this is a few degree F colder than what is shown in the comic which states the temperature is -452&amp;amp;nbsp;°F = 4.26 kelvin. This higher temperature may have been chosen to reflect that even the star light from other stars would increase the actual temperature.&lt;br /&gt;
&lt;br /&gt;
In the last panel with trillion years, we jump right past the Sun's Red Giant phase, to a panel looking much like the one after five billion years with only other stars. Over the next three trillion years the stars become fewer and fewer and dimmer and dimmer as they run out of fuel and fewer new stars form. After four trillion years the background temperature even decreases one degree to -453&amp;amp;nbsp;°F as the universe keeps expanding and the wavelength of the radiation does the same, thus decreasing its temperature.&lt;br /&gt;
&lt;br /&gt;
The title text is a play on comments referring to fast-changing weather on a more ordinary human timescale, such as Mark Twain's quip &amp;quot;If you don't like the weather in New England now, just wait a few minutes.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
A ten days forecast was used in [[1245: 10-Day Forecast]]. In [[1379: 4.5 Degrees]] Randall looked at the weather over long periods of time as well.&lt;br /&gt;

&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Created by a BOT EXECUTING REMOTE COD - Please change this comment when editing this page. Do NOT delete this tag too soon.}}&lt;br /&gt;
{{w|Remote code execution}} is a type of {{w|software exploit}} that takes advantage of a bug to allow a remote user of a computer application to make it run code that it was not intended to execute. For example, a webserver with such a bug might allow a user of a web page to make it run a program that deletes system files or displays private information.&lt;br /&gt;
&lt;br /&gt;
The joke arising from this comic is that if you remove the &amp;quot;e&amp;quot; from &amp;quot;code&amp;quot;, you get &amp;quot;remote cod execution&amp;quot;. This refers to killing (&amp;quot;executing&amp;quot;) codfish remotely, using an exploit in a network application that allows one to view the {{w|hatchery}}.&lt;br /&gt;
&lt;br /&gt;
The title text contains a pun on {{w|rainbow tables}}, referring to {{w|rainbow trout}}, one type of which ({{w|steelhead}}) is {{w|anadromous fish|anadromous}} (migrating up rivers to spawn -- {{w|salmon}} are another well known example). Rainbow tables are used when trying to crack hashed passwords; it's a file with a carefully pre-computed selection of passwords and their corresponding hash values, which can be used to more efficiently recover password that are retrieved hashed. To prevent rainbow tables from being usable in this way, most modern password systems use &amp;quot;{{w|salt (cryptography)|salt}}&amp;quot;, an extra random string that gets appended to the password before hashing so the same password will potentially have many different hashes, and it becomes infeasible to recover it even with the acceleration offered by rainbow tables. An additional pun is that rivers contain fresh water, so there's no salt (the chemical kind) and the fish are therefore more vulnerable.&lt;br /&gt;
&lt;br /&gt;
The comic dialogue itself starts the whole chain of puns off by using the phrase &amp;quot;shooting fish in a barrel&amp;quot;, which is figuratively used to mean that the task is extremely easy, but here becomes clear that he is literally {{w|Capital punishment|executing}} fish, without needing to be there in person. Also, Black Hat has [[374: Journal|previously]] talked about shooting &amp;quot;lonely, angsty fish in a barrel.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
It might also be a pun referencing Call of Duty, as the games acronym is &amp;quot;COD&amp;quot; and Black Hat is seen shooting something on a computer.&lt;br /&gt;
&lt;br /&gt;
{{w|Fish (Unix shell)|fish}} is also the name of a {{w|UNIX shell}}. Shells are popular targets for computer hackers as they are capable of being used to run arbitrary commands if sufficient access is gained through them.&lt;br /&gt;
