Theoretically you can get around this limitation by turning off the road before the sign and doing whatever maneuvers you need to out in the wide open area to the right or left of the road. It's not a U-turn if you're not on the road, and you didn't enter a restricted part of a road either, and didn't stop on the road. After which you calmly make a turn onto the road when traffic is clear. [[Special:Contributions/108.162.245.207|108.162.245.207]] 02:34, 14 October 2023 (UTC)&lt;br /&gt;

You could obey the title text if it was 45 miles per hour and 65 meters per hour, respectively. [[Special:Contributions/162.158.90.96|162.158.90.96]] 04:04, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Perhaps so, but anyone deliberately occupying a travel lane while going 0.06 kph (0.04 mph = 200 feet per hour) in a 45 mph zone would [ahem] rapidly attract attention for other reasons. If it were 65 *kilometers* per hour (40 mph), you'd have a narrow window of legality (I do drive on a road that has a max 45 / min 30 speed limit).

Take notice of the road markings too. At least here in Europe double white lines are not to be crossed. And they go past the point of the sign.--[[User:Henke37|Henke37]] ([[User talk:Henke37|talk]]) 07:06, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
: Aye - doesn't that combination of dashed and solid lines imply that there will be opposing traffic? Ie, the markings on the road expect traffic to enter past the sign, despite what the signs are saying, which adds another layer of absurd (Ignore the pole signs and use the lane on the right, otherwise the lane on the right can never be used?)&lt;br /&gt;
&lt;br /&gt;
I can't be the only one that sees a Gaza strip evacuation subttext to this. &lt;br /&gt;
&lt;br /&gt;
:Double lines are also &amp;quot;do not cross&amp;quot; in America. And I think in this case it's supposed to be yellow, the dashed-and-solid combo indicates a one-sided passing zone into a lane with on-coming traffic, and double lines in general are only use to separate anti-parallel lanes of traffic, both of which use yellow. &amp;quot;Solid double white lines&amp;quot; do exist, but are only used in very specific cases. Near me, there's a very congested exit, and the solid double whites are used to indicate &amp;quot;no really, you should have switched lanes ages ago, it's too late now!&amp;quot;, but since it isn't a Jersey barrier or a line of rods or even a full on median, nobody actually follows the rule. Anonymous 07:30, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
:: BTW in Europe, yellow lines are reserved for temporary use, and then take precedence over any existing white lines. Makes lots of sense, because there are so many construction sites here. (And the yellow lines are actually just adhesive tape.) --[[Special:Contributions/162.158.87.102|162.158.87.102]] 08:28, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
::: Back when elephants had fur, road markings in the USA were white. Starting in the 1950s, road crews throughout the USA began using yellow rather than white paint. From memory, it took about a decade for the transition to be completed, with more rural roads the last to go yellow. [[Special:Contributions/162.158.90.161|162.158.90.161]] 18:18, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
Speaking of lines ... in the USA, &amp;quot;Do Not Enter&amp;quot; signs on open roadways usually signal that the road ahead is one-way traffic coming at you. A driver is thereby warned (for example) not to enter the &amp;quot;exit&amp;quot; ramp of a freeway. However, the road striping indicates that passing is permitted for drivers proceeding forward past the sign ... which is nonsensical if the only legal traffic is coming at the viewpoint driver. I am reminded of the ancient comedy routine, &amp;quot;Somebody went to the Army-Navy store, got himself a sign, looked out his living room window, 'Look, Martha, we caught somebody!'&amp;quot; [[Special:Contributions/162.158.186.118|162.158.186.118]] 19:19, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
And I completely forgot why I was posting in the first place: I think there's good reason to create a full &amp;quot;traffic signs&amp;quot; or &amp;quot;road signs&amp;quot; tag, not just &amp;quot;traffic lights&amp;quot;. I know there's a page with a very complicated &amp;quot;this is what the road ahead looks like&amp;quot; sign that just says &amp;quot;good luck&amp;quot;, and of course there's &amp;quot;Next Five Miles&amp;quot; and &amp;quot;Ahead Stop&amp;quot;. Thoughts? Anonymous 07:58, 14 October 2023 (UTC)&lt;br /&gt;
:I would support that. I wanted to put this comic into a category but I couldn't find an appropriate one. --[[Special:Contributions/172.69.58.3|172.69.58.3]] 23:11, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
More thoughts: if you must not make a U-turn to the left, you should do it to the right.&lt;br /&gt;
And then return on the same lane, because of the double line.&lt;br /&gt;
And finally, the sign itself may be valid and not contradicting itself; it is your fault if you got on this road. ;) --[[Special:Contributions/162.158.87.102|162.158.87.102]] 08:28, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;
In the Netherlands, the message on signs are only valid behind the sign (with the exception of the &amp;quot;precedence way&amp;quot; (voorrangsweg), where outside of built-up areas, the signs are after a junction (though technically... way before the ''next'' junction) , so a driver stopping /u-turning here wouldn't be violating anything except the double white lines. &lt;br /&gt;
Also, stopping out of necessity (e.g. the car in front is also stopped) is ''never'' illegal. [[User:IIVQ|IIVQ]] ([[User talk:IIVQ|talk]]) 09:06, 14 October 2023 (UTC)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
If I had to comply with these instructions, I would just put the car into reverse and argue that I was never &amp;quot;stopped&amp;quot;. If I actually saw this in real life, I think I'd just slow down, put on my hazard lights, and make a u-turn when appropriate.[[User:Jsnider3|Jsnider3]] ([[User talk:Jsnider3|talk]]) 10:52, 14 October 2023 (UTC&lt;br /&gt;

&amp;quot;''Depending on the jurisdiction, signs may only apply to the road after them''&amp;quot; - uh, in which jurisdictions is that not the case?

: I don't know US signage, but there are times over here in my locale when there's repeater/reminder signage, the situation (such as not being allowed to stop) already being in effect past a prior point.

&lt;br /&gt;
Since the lanes are separated by white lines instead of yellow, that means that the two lanes of traffic are going in the same direction. There isn't any roadway visible onto which one could make a U-turn even if it were permitted. --[[Special:Contributions/172.69.59.204|172.69.59.204]] 23:07, 14 October 2023 (UTC)&lt;br /&gt;

&lt;br /&gt;
Not even that uncommon. I find no U-turn signs get placed places where a lot of people do u-turn, often because they NEED to make a u-turn due to another previous sign issue. So having to do u-turns where no u-turn signs are, is like the f'ing default.[[Special:Contributions/162.158.95.187|162.158.95.187]] 08:41, 16 October 2023 (UTC)&lt;br /&gt;

== &amp;quot;No stopping at any time&amp;quot; and max/min speed contradiction ==&lt;br /&gt;
&lt;br /&gt;
The &amp;quot;No stopping at any time&amp;quot; never applies if it is not possible to continue. If there's a traffic jam, nobody expects you to continue going and hitting a preceding vehicle. I'm pretty sure this meaning is the same in USA as it is in Europe.&lt;br /&gt;
&lt;br /&gt;
In Europe, speed limit takes absolute precedence over minimum speed, and for clarification, minimum speed only means that vehicles that cannot sustain minimum speed are not permitted on the road. It also signifies that if the road is clear and weather permitting, it is safe to drive at that speed.&lt;br /&gt;
But, if you're not confident in your driving ability, or in inclement weather, or if there is traffic, or for any other reason, you're not expected to continue driving at that speed.&lt;br /&gt;
Motorways and expressways in Europe have an implied minimum speed of about 60 km/h, but if there are roadworks which have a posted 50 km/h or 40 km/h speed limit, you're not expected to drive 60 km/h and you'll be violating the law if you do.&lt;/div&gt;</summary>

;Title text - Our retina display features hundreds of pixels per inch in the central fovea region.&lt;br /&gt;
There is so much language in this and a big error not covered here:&lt;br /&gt;
*''Our'' isn't them, it's us! We all (mostly) have two eyes and the retina collects visual information in pixels.&lt;br /&gt;
*But hundreds of pixels is far too low. The Wiki article {{w|Fovea centralis}} tells me &amp;quot;50 per 100 micrometres in the most central fovea&amp;quot;. This is approximately 12,700 per inch. This would lead to roughly 162 GigaPixels.&lt;br /&gt;
*And then the human eye isn't large as an inch, and the &amp;quot;most central fovea&amp;quot; is much smaller. Maybe Randall will correct the &amp;quot;hundreds of pixels per inch&amp;quot;...&lt;br /&gt;

[[First]] post!!!!!!!!!!!!!!!!!!!!!!!!!!! Anyway, the explanation looks like a train wreck, and I'm not sure if a rearranging it into a table or just adding bullet points to everything is better. I'm guessing that a table would be better, but I don't know how I can rearrange it. Can somebody help?

:: Thanks, I think a table is a good way to go. I'm adding it to the article as a place to start. Rather than format the original explanation into the table, I'm leaving the cells blank.

Regarding &amp;quot;Factor a prime&amp;quot;: Factoring a prime is easy: The prime itself is the only factor, so it's sufficient to use [https://en.wikipedia.org/wiki/AKS_primality_test AKS] or whatever to check that. Public-key encryption relies on how hard it is to factor the product of two primes, which is a much harder problem. Maybe this is a typo in the comic? {{unsigned|Comment Police}}&lt;br /&gt;
: I don't think it is a typo. It's exactly the type of &amp;quot;inside-joke&amp;quot; I would expect from XKCD. :) --[[Special:Contributions/162.158.134.214|162.158.134.214]] 10:09, 19 February 2018 (UTC)&lt;br /&gt;
:: AFAIK, there aren't any primality tests known to run in O(log n). For instance, AKS runs in O(log n ^ 7.5). So for numpy to actually achieve factoring as stated would require assuming the input is prime and just returning (1,n). --[[User:Quantum7|Quantum7]] ([[User talk:Quantum7|talk]]) 12:45, 19 February 2018 (UTC)&lt;br /&gt;
:::Doesn't testing for primality (just) require a list of all primes up to sqrt(n)? So the best possible time is sqrt(however fast you can calculate primes up to a number). That time can at most be square (divide every number by every other number below it), so a primality test only needs O(n) time. Or do I understand something wrong? [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 13:46, 19 February 2018 (UTC)&lt;br /&gt;
::::Oh yes, I missed that log(n) is less than n. Nevermind then. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 13:50, 19 February 2018 (UTC)&lt;br /&gt;

I think the explanation of the one about injecting arbitrary text onto a page with the comments box is overthinking the joke. I think it really is just about the fact that you can write whatever you like in a comment. Look, I just hacked this page to display the word &amp;quot;penguin&amp;quot;.

I've added some clarification to the &amp;quot;CRITICAL&amp;quot; item. I know there are several xkcd comics referencing similar problems but I unfortunately don't have the time to look them up, can someone do that and link them appropriately in the table? [[User:Domino|Domino]] ([[User talk:Domino|talk]]) 13:11, 19 February 2018 (UTC)domino&lt;br /&gt;
:Isn't the joke really in the hilarious severity assessment? The vulnerability is supposedly CRITICAL!!!!11!1!!one!, while description shows both a ridiculously small vulnerable population and ridiculously low impact. Population: a single, very old kernel version on a rare, outdated architecture, in one timezone only - and WHICH timezone! UTC+14 means just a couple of islands in the Pacific (Tonga, Kiribati...) - the probability of even one vulnerable system actually existing seems almost zero. Impact: the only possible consequence is switching from 12h to 24h (only in this direction)? This whole entry is very creative - just TRY to come up with a possible vulnerability (yes, it would classify as an actual vulnerability, why not?) that would have a LOWER severity than that...--[[Special:Contributions/162.158.91.89|162.158.91.89]] 13:41, 19 February 2018 (UTC)&lt;br /&gt;
&lt;br /&gt;
I think the article should start with an explanation of what is the CVE. From https://cve.mitre.org/&lt;br /&gt;
 &amp;quot;CVE® is a list of entries—each containing an identification number, a description, and at least one public reference—for publicly known cybersecurity vulnerabilities.&lt;br /&gt;
 CVE Entries are used in numerous cybersecurity products and services from around the world, including the U.S. National Vulnerability Database (NVD).&amp;quot;&lt;br /&gt;
-{{unsigned|Comment Police}}&lt;br /&gt;
&lt;br /&gt;
&amp;quot;MySQL server 55.45&amp;quot; it is 5.5.45 if you zoom in a bit. [[Special:Contributions/162.158.91.161|162.158.91.161]] 13:41, 19 February 2018 (UTC)Blocki&lt;br /&gt;
&lt;br /&gt;
&amp;quot;An attacker can execute malicious code on their own machine and no one can stop them&amp;quot; might be a jab at the trend toward more closed systems, where even the owner of a device is limited in what they can do on it. &amp;lt;br/&amp;gt;&lt;br /&gt;
&amp;quot;A flaw in Mitre's CVE database allows arbitrary code insertion&amp;quot; could be meant as an explanation for the whole comic, i.e. those joke vulnerabilities were added to the CVE database using this flaw.

|Oh, just hit both shift keys to change over to QWERTY.&lt;br /&gt;
| Likely has keyboard in DVORAK &lt;br /&gt;
|-&lt;br /&gt;
|Caps lock is control. And spacebar is capslock.&lt;br /&gt;
| Changing Caps Lock to a &amp;quot;more useful&amp;quot; key is common. However to change an even larger key to be capslock (Space) is odd&lt;br /&gt;
|-&lt;br /&gt;
|And two-finger scroll moves through time instead of space.&lt;br /&gt;
|Two finger scrolling is often used to move through a document or application on a mousepad or touchscreen device - this could be seen as moving through space (despite the cursor not actually being real). Randall is presumerably making a comment re: Space Time continuum or similar?&lt;br /&gt;

|Once I've used a computer for a while no one else will ever use it again.&lt;br /&gt;
