Title text may refer to policy decisions in the second Trump administration which promote the use of fossil fuels or undo existing policies which promote the use of renewables.

Unrelated but I had a dream that I checked this website and it was Randall announcing he was going to quit, just text on a white panel as the final comic, not too dissimilar to Schultz quitting Peanuts.

:Charles Schultz died on February 12, 2000, the day before his last Sunday strip was published.

: Or something to do with gender/hormones as the other 2 skunks are agitated near females (coincidence in an XKCD strip? I don't think so.)

We don't know the rules of the game, and the host did not state clear instructions on what's to do.

The offset rig one could be a reference to speed record sailboats. (https://en.wikipedia.org/wiki/Vestas_Sailrocket) For torque reasons, they have the mast mounted on a horizontal boom and offset far off the side of the boat. Though on the other hand, speed record boats have this boom above the water, and only have single sails.

:That looks to me more like a form of catamaran (or partly-inline trimarang).

The definition of yawl is wrong. What matters is not position of mizzen relative to rudder post, but to water line. Ketches often have the mizzen mast behind the rudder.

Bunkbed rig could also be reference to a Hydrofoil, the idea that the boat moves so fast it climbs out of the water. [[Special:Contributions/198.180.154.20|198.180.154.20]] 15:48, 13 January 2026 (UTC)

The "OOPS, ALL SPINNAKERS" could be made to work (although only sailing downwind, and only up to the speed of the airflow) by using spinnakers increasingly tightly woven so that the upwind ones would let pass most of the airflow with the subsequent ones being increasingly tightly woven, thus minimalizing the loss of efficiency due to the escape of airflow around the edges of each spinnaker. Such a setup could potentially allow to maximize the use of the airflow force when sailing directly downwind, although the increase in complexity and wheight would likely lead to an overall loss of efficiency compared to a single, well-designed spinnaker. In any case the spinnaker (basically a parachute on a mast) is only designed to add a little extra boost when sailing downwind in a strong wind for a relatively long time (when the main sails can't catch much wind; in this configuration the main sail(s) are typically angled at a very wide angle against the airflow which is very suboptimal for a "foil" sail), in all other cases the foil-like sails are much more efficient and do allow to sail faster than the wind, which the spinnaker can't achieve, by design.

: Imagemagick is the de-facto standard for Image processing. Since the 90's engineers were either adding support for new formats to ImageMagick or adding new language bindings for ImageMagick. This resulted in a single library that is available on almost every server and desktop platform and can read and write almost every image format. Using imageMagick is sometimes unwieldly. e.g. on nodeJS it actually spawns a sub-process to run imagemagick.

I'm pretty sure re-use and modularization was a thing long before then. Maybe it got more popular in the 2010s, but it's been around since at least the '70s.

The timezone database (https://en.wikipedia.org/wiki/Tz_database#History) has been around since 1986. libc in various forms has been around as long as C has. Reuse and modularity is a fundamental principle of software engineering, and not an invention of the last few years. I'd just remove any mention of date.
: I think it's relatively recent that you can delete a file from one Web server and everything on the internet breaks. Dependencies are one thing, dependency on live updated resources is new. Because it's rather a bad idea. Incidentally overall... I think today's comic needs to be explained slower. Most people in the world are very unfamiliar with these concepts.

On December 9, 2021, security researchers discovered a flaw in the code of a software library used for logging. The software library, Log4j, is built on a popular coding language, Java, that has widespread use in other software and applications used worldwide. This flaw in Log4j is estimated to be present in over 100 million instances globally. If exploited, could permit a remote attacker to execute arbitrary code on vulnerable systems. This library had one maintainer who lived in the outback.

== Explain “maintenance” ==
What this article does a poor job of is explaining what software “maintenance” is. Software doesn’t usually disappear (despite the several cases mentioned in the article which are kind of beside the point). It also doesn’t rust or wear out like a car. But software usually needs to be continuously updated to fix security vulnerabilities or to keep it compatible with other software. Also it can get new features or bug fixes. And if the guy in Nebraska doesn’t do a good job of it, everyone has a problem.

Also worth mentioning is how the comic highlights the absurdity of this anarchic communism. Neither users (capitalism) nor the government (socialism) is paying these people. And somehow it works 95% of the time. Except when it doesn’t.

I ran some numbers, and assuming 28.349523125 grams in an ounce and 16 ounces in a pound, "7 kg and 9 ounces" would be 7255.145708125 grams, assuming the "9 ounces" doesn't involve rounding, while 16 pounds would be 7257.47792 grams, which differs by only about 2.332211875 grams, or about 0.08 ounce - it's possible the weight is actually 16 pounds exactly, which feels like it makes "7 kg and 9 ounces" even worse than it already is.

:"Air," "Lead," "Water," and "Glass," and a near-perfect "Vacuum" actually vary by thickness. I guess Oven mitts, armor, bio-hazard suits, faraday cages, and shark cages do too but those usually come in human-scale sizes. A meter of air won't give you significant protection against gamma rays, but if you are anywhere near sea level, the air above your head does. A near-perfect vacuum too wide for a shark to get to you before it dies will protect you, one only a few nanometers thick probably won't.

64.201.132.210: /* Explanation */ citatoin to theory that Earth may have had a ring system in the past

==Explanation==
{{incomplete|This page was created by an off-axis satellite dish. Don't remove this notice too soon.}}
A {{w|ring system|planetary ring}} is a disc of small objects and other material orbiting a planet. The most well known are the rings of {{w|Saturn}}, which were discovered by {{w|Galileo Galilei}}, but all the {{w|gas giant}} planets in the Solar System have rings, as do some minor planets and moons.

Earth does not have a natural ring system, although it's theorized that it may have had one in the distant past.[https://web.archive.org/web/20250401024532/https://time.com/7022440/earth-ring-like-saturn-study/] However, since the 1950's (about 68 years ago at the time this comic was posted) we have launched many artificial satellites into Earth orbit, and most of them orbit in the equatorial plane (a small number are in {{w|polar orbit}}s), so they constitute an artificial ring system.

{{w|Satellite dishes}} are used to communicate with most of these devices. But since some are used for communicating with polar satellites and space probes, it's not all as claimed by the caption.

:"Gen-ed" is general education. It probably refers to classes that satisfy the "core requirements" that everyone graduating from the institution must pass, regardless of major. Typically these will include English composition (basically, how to write a paper), some first- and maybe second-year humanities classes, some first- and maybe second-year science or engineering classes, and some first- and maybe second-year math. These days, many US students graduate high school with college credit for some of these classes through dual-enrollment classes, Advanced Placement classes (and the required test), or similar programs (it's not unheard of to start university as a "third year student" - or "Junior" in US education lingo). "400" means 4th-year classes (individual classes will be numbered 401, 402, etc.), which are typically only available to students majoring in that topic or a related topic. Fun fact: In some graduate schools, students are allowed to take a limited number of "400" classes to meet their graduate degree requirements.

I think "speedrun University" can also implies someone trying to finish university ahead time interval (4 years, usually). I know people who have enough AP credits and do enough over-loading and summer classes trying to finish university within 2 years (the minimum time required to get a degree for most university). On the other hand, I believe this comic hint the people trying to complete all major's requirement inside the University to get "100% achievement". Most of university do not allow anything above double-count (count one class for more then 2 major requirements). If the people in comic have complete more then 20 major requirement within 15 years, that translate to the people have take enough class to complete at least 10 major's class/graduation requirements under the no triple count rule. in average, complete 1 major per 1.5 years, which in some sense, is amazing, also count as "speed-run". --(Someone recently been bitten by University's major tracking sheets) [[Special:Contributions/130.215.10.247|130.215.10.247]] 14:41, 30 September 2025 (UTC)

Interesting. Just a few days ago I was investigating a very similar idea (looking at a path that transitioned between adjacent ''faces'' of a polyhedron, which was effectively going from vertex to connected vertex upon that chosen polyhedron's ''dual''), but for the opposite reason, i.e. looking for the paths that actually maximised proximity (along the path) between neighbouring faces (upon the polyhedra), so that it actually minimised the search back/forth along the path-chain to establish what value the adjacent polyhedron faces (beyond the ones automatically at ±1 positions on the chain) inherited.
 As to solving this one (basically disallowing visiting of any nodes adjacent to prior visits ''other'' than the single one that the +1 position of the chain has to first go to), I've got a basic idea of how I'd N-dimensionally space-search the possible routes (after all, visiting any given node at {0,1} value for dimensions [a, b, c, ...] rules out now visiting all of [!a, b, c, ...], [a, !b, c, ...], [a, b, !c, ...], etc, ''except'' whichever one of these was chosen for the next step of onward travel), for valid foldings across the appropriate N-polytype cuboidal analogue. Though I suspect that the exponental (or greater!) growth in the potential search-trees you'd use would be the sticking point. No point in setting off an exhaustive algorithm if it seemed likely to take three years to check just 1% of possibilities, and no doubt more dedicated analysis than my own brute-forcing method has already hit other problems in trying a more nuanced extrapolation between each level of added dimensionality, which is where the unsolved nature of this starts to bite.
 But also think it'd be far more interesting to investigate the possibilities in the N>3-Dimensional extensions of non-cubic platonic solids, like the {{w|600-cell}} and beyond, and establish what allowable lengths of traversal ''they'' would allow, under similar stipulations.
 Great! I love getting things like this to think about. If I can spare the time needed... [[Special:Contributions/82.132.245.59|82.132.245.59]] 22:22, 6 August 2025 (UTC)
: I think you've been nerd-sniped. [[Special:Contributions/177.12.49.23|177.12.49.23]] 22:42, 6 August 2025 (UTC)
::So far, I've personally got as far as:
::*For any given number of dimensions, N, there are always N adjacent points (point, zero dimensions, zero neighbours; line, one dimension, one neighbour; square, two dimension, two neighbours, etc).
::*In total, there are 2N points (0d=1, 1d=2, 2d=4, etc)
::*A maximum possible length, L, has a ''lower'' lower limit of starting at any particular vortex and only taking directions that are perpendicular to all prior directions (for a cube, only go by x, y and z directions once), and this would be eaual to N.
::*But that's overly-lazy, as you're ruling out (as you gain enough dimensions) revisiting a dimensional plane, even though you're allowed to revisit a point on that plane that's shifted by at least ''two'' other dimensions of offset. e.g. the top right of a cube's facing face when you started at the bottom left of it (went 'deep' to the rear face, took two steps from the rear-lower-left to rear-upper-right then back).
::*For the first step, you have N choices from your starting position. You take one and cannot later visit any of the ones you did not choose to go to. For the second step onwards, you have N-1 basic choices (every direction but backwards to the prior step) and should choose one and rule out ever visiting the rest.
::*This gives a new (at least for N>2) lower limit to L whereby the sum of starting, taken and not-taken nodes that you count can be added to by new steps until you would end up with have a total greater than 2N. (Line: start on one (of two), choice of one (taken), two points 'marked', only two points possible; Square: start on one (of four), two choices, take one, reserve one, three points 'marked', still the fourth point available for L=2, but then five points would be marked (the untaken-from-start being the only non-backwards choice) so can't go further.
::*But this is also wasteful as (in increasingly higher dimensions) there's nothing to stop an unvisited neighbour of a past step from being a(n enforced) unvisited neighbour from a later step, as you 'choose' to go only to a valid further point. So clever "near-neighbour" backtracking can reduce the number of ''freshly'' eaten-up points and thus maintain more future points for more steps.
::**Noting that past-step no-go-neighbours that can possibly 'fold into' the current-step's not-going-neighbours list only become such after ''at least'' two intervening steps (for 'square-based' hypercubic domains, whereas triangle-based hypernets (e.g. tetra-, octa- and icosohedrons, in 3-space) happen after just one step, and pentagon-based ones (dodecahedrons in 3-space) can't take advantage of this in less than three. (This seems to share some of the mathematics with the 'classical' rabbit-population problem, whereby new offspring only become viable breeding population after a step or two since their generation.)
::*Optimally, in fact, you should aim to double-back in such a way as leave yourself with ''all but one'' onward neighbour unavailable (thus only eating up potential points at a rate of one per step, at that point).
::*Heading vaguely back 'towards' past snake-lengths, in higher-dimensional hypernets, seems like the best(/longest) space-filling strategy. It's a bit like coil-built pottery, but with more undulations (and dimensions) to it. But with care to make sure you don't burrow yourself into a dead-end with ''no'' viable onward choices while still having maybe half of the potential visitable/neighbourable points untouched, or avoiding filling 'voids' to guaranteeing accessing a majority of the potential future visits, but unwisely not exploiting all the phase-space of vertices optimally.
::**I can mentally visualise doing this successfully in 3-, 4- and 5-cube situations, elegantly enough (it's like , but N>=6 versions get increasingly hard to do in my head with certainty. After I've slept on it, I might have to break out the pencil and paper.
::So, yeah, I've set a lower-limit to L, for various Ns, and can construct a ''possible'' upper-limit to L, but I haven't even checked these L(N)s vs. the values stated in the comic. Or what progress (and more advanced logical reasoning) has already been made in the field. I suspect I'm just reinventing the (hyper-)wheel, of course, rather than have the key to the problem that everyone else had failed to spot, but that's not the point. If I get even half way close to what the 'professionals' in this field have managed, I'll be smug and self-satisfied enough for myself. And, anyway, I've explained myself enough tolet any ''other'' similarly-minded nerd the ability to get at least as far as I've got with this problem.

That's wrong and misses the point of quantum superposition. The cat is not dead or alive, it's literally both, due to its fate being linked to radioactive decay, a process that is subject to quantum superposition.

Is it just me, or is xkcd.com being non-responsive? Obviously, it has been successfully grabbed from by the BOT, and I even checked a few "is it down" sites... which say that it's up.

Hmm. If material from the banded iron formations was mixed with coal, and subjected to the heat and pressure that create metamorphic rock, would iron be created? There would still be the problem of keeping it free of ground water so it didn't go back to iron oxides. [[User:BunsenH|BunsenH]] ([[User talk:BunsenH|talk]]) 04:48, 8 July 2025 (UTC)

{{comic

}}

==Explanation==
{{incomplete|This page was created by an IRON-RICH BOT. Don't remove this notice too soon.}}
Someone has been stabbed dead and two geologists are looking at the corpse. As they apparently have no forensic experience or ability, they apply their geological knowledge. The "iron-rich intrusion in his back" refers to the dagger that killed him; an {{w|intrusion}} is rock formed when magma slowly cools below ground, and the geologists are speculating that the dagger formed after steel flowed into place in and on the body (and somehow became dagger-shaped). The dagger is "iron-rich" because it's made of steel, which is composed largely of iron. "{{w|Clastic rock|Clastic}}", mentioned by one geologist, refers to rock made up of broken pieces of older rocks. In this case she's speculating that a {{w|rift}} - a gap - opened up in the person's back and the dagger fell in. Having long linear gaps appear is something that happens to the Earth's crust, and can lead to clastic rock when other rock is swept into the gap. However, this doesn't normally happen to people's backs.{{cn}}

The "pipes carrying iron-rich fluid" are the person's blood vessels, as blood has a large amount of the iron-rich molecule {{w|hemoglobin}} to help it transport oxygen. The geologists speculate that the iron {{w|Precipitation (chemistry)|precipitated}} - sedimented out - out of the blood to form the dagger, which is of course ridiculous.

==Transcript==
{{incomplete transcript|Don't remove this notice too soon.}}

[There's a lab bench with a dead Cueball lying on it, with a dagger sticking out of his back. Another Cueball is standing to the left of the table, Ponytail is standing to the right. They're each wearing lab coats and looking at the dead body.]

Cueball: We found him lying uncofmortably on the lab bench. I wonder if the iron-rich intrusion in his back is related.

Ponytail: It could be clastic. Maybe a rift opened in his body, and the intrusive material later fell into the hole.

Talk:3109: Dehumidifier

2025-06-30T20:31:45Z

64.201.132.210: If they discover a new kind of water ...

Having network access can have some use for a dehumidifier, e.g. to remotely set the target humidity level, or get notifications when the water tank needs to get emptied. But having devices that depend on a specific app or a vendor-provided remote service risks having a useless device after a while ... --[[Special:Contributions/134.102.219.31|134.102.219.31]] 13:19, 30 June 2025 (UTC)
:Humidifiers typically have a physical control to set a target humidity level, and even the most basic models turn off when the water tank gets full. Since humans can't really tell the difference between 40-60%, which is the range of most humidifiers, there is no need for a remote control to change the humidity levels on a machine. As for the water tank, regular use of the humidifier will teach the user about how long it can run before turning off and needing to be emptied. {{unsigned ip|136.62.110.93|13:58, 30 June 2025 (UTC)}}
