Tried [1] and of course also the dezoomify tool but got immediately stuck because I was not able to find an URL. Very few programming skills, none regarding HTML, that's why I ask here.--Antemister (talk) 10:46, 6 January 2025 (UTC)[reply]
I wasn't able to download the file as it was taking forever, but this URL appeared to download the files for 30+ minutes on a fast internet. Let us know if this works. TheTechie@enwiki (she/they | talk) 03:19, 8 January 2025 (UTC)[reply]
I've successfully taken images off the IWM via their source code and dezoomify, but I'm puzzled as to how to extract images here, as Dezoomify appears to be perpetually stuck on 'preparing tiles load'. The longest I've seen it take for large images in the past is a couple of minutes. Like Antemister, I've little programming knowledge, but I think the following elements in the code are related:
It's still potentially in violation of their ToS (not that I much care) and could, per my reading of my law (assuming this is an american website, which it isn't) run afoul of something like the Computer Fraud and Abuse Act.
Even if all you say were true (It's highly doubtful; there appear to be no published terms of service - much less any that a user agrees to before viewing the site; and in any case we are not all in the USA), it's still not theft.

Yes, I came to that cited code, but had no idea to open that container
Also tried again dezoomify, and also waited a long time, and after 1-2 hours i get an error message. And it includes a link, [2], if you alter the numbers you can find various tiles of the map.is it possible to proceed with that, download that folder?--Antemister (talk) 22:34, 8 January 2025 (UTC)[reply]
Hmm! So I pasted this conversation into ChatGPT, and told it to generate code for use in Google Colab. The code is here (it doesn't really do what it's supposed to, at all, but a start).
I gave this another try. This time it was able to actually download the image correctly, but only a horizontal section. The code is collapsed below. I think it needs only some slight tweaking.

User:Antemister, it was one of the bottom sections of the map, I have some silly 2FA on my devices and can't access the one I ran it on for a couple of hours. You should be able to run the above code in Colab and ask ChatGPT (or Gemini) for further help. JayCubby17:02, 9 January 2025 (UTC)[reply]
Antemister In a new cell, type
from google.colab import files
files.download('merged_image.jpg') Apologies for putting all of this inside a hat template, I can't figure out how to correct it. JayCubby18:15, 9 January 2025 (UTC)[reply]
Again progress, have gotten such a merged image that shows a part of the map. The iteration is just a guess... Shouldnt there be a possibility to list all the files in the folder?--Antemister (talk) 22:58, 9 January 2025 (UTC)[reply]
@Antemister, I very nearly got it to work, the final image is 12,000x12,000px but has errors. import os
Thank you, that is sufficient, what I need is the ceasefire/demarcation line. Can you sent me the code with correct formatting? Maybe I can use it in future, to download other zoomified images.--Antemister (talk) 14:18, 11 January 2025 (UTC)[reply]
A meteorite is 600ft from a satellite and travelling toward the satellite at 42ft/sec. At what times will the meteorite be less than 50ft away from the satellite? Write an appropriate absolute value inequality for the given situation and solve:
Let|42t-600|<50 and 42t-600<50 and 42t-600>-50. Thus, 13.10<t<15.48. Afrazer123 (talk) 22:21, 13 January 2025 (UTC)[reply]
What is the question?
The given data do not specify where the meteorite is at time t = 0, and also not with which speed the satellite is moving. Your solution is based on the (not unreasonable) assumptions that the person who drew up this assignment meant t = 0 to be the initial moment when the meteorite is 600ft away from the satellite, and that the speed of 42ft/s is the speed of the meteorite relative to the satellite. Your solution assumes that the meteorite will not hit the satellite, but pass by it. Under these assumptions, the derived inequations are correct, as is your solution, although not with exact values but with numeric values rounded to two decimals.
If the meteorite hits the satellite, we don't know what happens after t = 14.29. If the satellite disintegrates, the notion of the distance between the bodies becomes meaningless. --Lambiam23:59, 13 January 2025 (UTC)[reply]
Welcome to the Wikipedia Reference Desk. Your question appears to be a homework question. I apologize if this is a misinterpretation, but it is our aim here not to do people's homework for them, but to merely aid them in doing it themselves. Letting someone else do your homework does not help you learn nearly as much as doing it yourself. Please attempt to solve the problem or answer the question yourself first. If you need help with a specific part of your homework, feel free to tell us where you are stuck and ask for help. If you need help grasping the concept of a problem, by all means let us know.
But is it homework? Homework formulates an exercise, often in the form of a problem, asking for its solution. It is not usual for homework to contain the detailed solution to a stated problem. What is then the exercise? --Lambiam10:32, 15 January 2025 (UTC)[reply]

if a < b, then b <⃥͏ a (asymmetry) — after the second italic b
What are they? In both cases that I copied, the box is seemingly the same character as the lesser-than sign, since I can't highlight one without the other. I figured I could get the answer from Google (there are enough Unicode charts online), but I get just four results for the combined lesser-than-and-box: the inequality article, two Reddit pages, and something in Thai. When I put the combined lesser-than-and-box into the URL, I'm shown MediaWiki:Badtitletext, which makes sense for a title containing a standalone < character, but not for one where the < elements are part of a special character. Nyttend (talk) 20:29, 15 January 2025 (UTC)[reply]
A less-than with two combining codes:
index chr codepoint utf8 cat name
0 < U+003c 3c Sm LESS-THAN SIGN
1 ⃥ U+20e5 e283a5 Mn COMBINING REVERSE SOLIDUS OVERLAY
2 ͏ U+034f cd8f Mn COMBINING GRAPHEME JOINER
In other words, it's a "not less than" sign. Unicode's single character for that is hex 226E or ≮, although it uses a slash rather than a backslash ("reverse solidus") to overstrike the < sign. --142.112.149.206 (talk) 02:47, 16 January 2025 (UTC)[reply]
Latex also uses The use of a forward slash, as in to mean is standard. I can't think of a reason for using the backslashed symbol instead and have replaced <\ by ≮. --Lambiam09:27, 16 January 2025 (UTC)[reply]

I have a Dell Inspiron 3910 running Windows 11. It has a C: drive with what is shown as either 216 GB or 232,783,867,904 bytes. (So those are 216 binary gigabytes, of 2**30 bytes each.) Anyway, This PC usually shows that it has between 20 GB and 45 GB free. If the free storage becomes less than 10%, it displays a red bar in This PC. One parameter that I am familiar with that changes is the size of pagefile.sys, which starts as 12 GB and often increases as it runs up to 24 GB or even 28 GB. I sometimes see the free storage on the C: drive drop to as low as 16 GB, which doesn't bother me, even if it bothers This PC. I don't need unlimited free storage on my C: drive; I need enough free storage on my C: drive. What happened yesterday is that it began displaying that about 5.5 GB was free, much less than I have seen before. I hadn't done anything that should have filled up the C: drive, such as importing video clips from my phone. (I know that video clips are large because they are three-dimensional because time is the third dimension.) I found a few folders on my C: drive that were at least 1 GB and I wasn't using, and I moved them to the E: drive, which is a great monster of a 4TB solid-state device. I thought that might free up a few gigabytes, and it didn't change anything. At about this point Windows Update told me that operating system updates were ready to install, and so I needed to schedule a time for a system restart. After the restart, my C: drive shows as having 44.9 GB free. That is, approximately 39 GB was reclaimed during the restart. I know that approximately 10 GB of that was pagefile.sys. Where did it get more than 25GB of free disk storage from? Is there a way that I can free up this disk storage other than by a restart? I know that some of this was temporary files created by Google Chrome and Microsoft Edge and a few other standard programs. Is there a utility that I can use that frees up temporary storage without restarting Windows?
Robert McClenon (talk) 18:10, 16 January 2025 (UTC)[reply]
@Robert McClenon I don't know of any program that finds temp files, but a good guideline I have in general is to use something like WinDirStat or WizTree (preferably the latter), as both show a graphical display of the biggest files on your drive, and may help in this case. TheTechie@enwiki (she/they | talk) 21:44, 16 January 2025 (UTC)[reply]
Thank you, User:TheTechie. I had already been using Disk Space Analyzer Max, which showed me the directories that were using a lot of space, and that didn't help much. What I saw was that Google Chrome had a large amount of data, for instance, but I didn't know what Google Chrome data was useful to it and what was temporary. As I said, I tried moving a few directories, each of which was about 1 GB, from C: to tertiary storage, and that didn't help. I thought it would make about 3 GB free, but maybe it took Windows a while to catch on. Obviously the restart found and freed up a lot of storage. So I am asking whether there is some way other than restarting the system to get it to find and free up the storage. Maybe I am looking for something that either does not exist or is buried somewhere, like treasure. Robert McClenon (talk) 22:19, 16 January 2025 (UTC)[reply]
If it's Google Chrome that's the culprit, have you tried clearing your cache and browsing history? For me, caching and history have led to many GiBs being used in Chrome in the past. TheTechie@enwiki (she/they | talk) 23:07, 16 January 2025 (UTC)[reply]
Thank you, User:TheTechie - That is useful advice. If I see that Google Chrome is using a lot of SSD space, I will purge its cache and browsing history. I assume that advice also applies to any other web browser. More generally, I infer that if any application is using a lot of temporary space, it can be nuked if there is an option in the application to nuke the temp storage, and, if not, it can always be restarted. Apparently a lot of applications clean up their own litter boxes when they start up. In this respect they are unlike cats. Robert McClenon (talk) 17:25, 17 January 2025 (UTC)[reply]
Install WizTree (free), boom, gives you an overview of everything stored on your storage volumes. Also lets you manage said stuff.
Anything called "cache" or "temp" can be safely nuked. A cache is just copies of things stored for speeding things up and can always be regenerated. In fact I suggest just making your browser shut off disk caching, which is largely unneeded these days unless you're on a slow connection, and eats away at the lifetime of SSDs, which it sounds like your primary drive is. Web search "<name of browser> disable disk caching"
So I am asking whether there is some way other than restarting the system to get it to find and free up the storage. It's hard to give a useful general answer to this without knowing what is taking up said storage to begin with. Remember we're not there with you looking at your computer screen; we can't see what's on your drives. The most generic answer is "sure there is as long as the things taking up space aren't locked Windows system files, which require a restart in order to modify/delete them." Software can always be configured to run periodically to go through deleting stuff "in the background".
For one you mentioned pagefile.sys—the Windows page file, which you probably have Windows "managing" the size of on its own (the default). Windows likes to be generous with its size and reserve more than you probably need, which then sits there taking up space. If you have no plans to use hibernation, on a typical modern PC you can usually get away with just disabling it altogether, though you might want to leave a bit of margin and set it to half your RAM size. For this Web search: "Windows change page file size". --Slowking Man (talk) 04:12, 17 January 2025 (UTC)[reply]
Thank you, User:Slowking Man. I have a disk analyzer, but will also try the one you recommend, and see which one gives me more what I want. When you say that you infer that my primary drive is an SSD, I think that you mean that my secondary storage is an [[SSD], because my primary storage is my 12 GB of RAM, and my secondary storage on the C: is a 216 GB SSD, which is what was getting full. Robert McClenon (talk) 17:25, 17 January 2025 (UTC)[reply]
Yeah. In computer-ese "storage", unqualified, is usually referring to persistent storage, stuff that keeps what's there without needing continual power, which excludes "RAM". And 12 GB is definitely a healthy amount; unless you're doing intensive things like 3D graphics design or playing graphics-intense 3D video games, you can get away with just disabling the page file entirely if you want.

The instructions specify: "You need macOS 14.3.1 or earlier for this to work. Items.data is encrypted in 14.4 and later."
I currently do not have any Apple hardware, so I plan to purchase a "mac mini, m1, 2020" machine. After I receive the machine, I plan to factory reset it for security.
After a factory reset, is it possible to install a specific version, such as 14.3.1 onto the machine?
(My understanding that if I just use the regular "system update" path, it would it me directly to the latest OSX, which is currently 15.2.) Epideurus (talk) 21:42, 16 January 2025 (UTC)[reply]
I haven't spent a dollar on this project yet, so I'm very flexible. I'm also pretty open-minded and will choose any brand or solution that fits my needs. I'm basically looking for a tracker to put in my bag so that I don't lose it.
I checked out the existing tracker networks and there's basically only two major ones: Apple AirTag and Google Find My Device. The former network is much larger than the latter, at least in 2025[3][4]. The size of Apple's network (number of Apple smartphones in the wild) enables my bag to be tracked accurately, without me having to ever carry an Apple smartphone.
I'm usually not a fan of closed and propriety systems, but in this case it could take years before Google's (slightly more) open system catch up in network size unfortunately. Epideurus (talk) 17:48, 17 January 2025 (UTC)[reply]
Solution A: If I put an airtag on my bag, then I can know where it is at all times, with 2 minute updates 24/7. (Regardless of where I physically am, or what phone I'm using.) This is because there are Apple devices blanketing the NA city that I live in, and they are willing to report the location of my bag to the Apple servers, without any payment or involvement from me.
Solution B: If I buy a similar device from another manufacturer, let's say Google or Samsung, then their location service would report my bag as being in my house, but with minimal location updates in the future. This is because there aren't any Google or Samsung devices in my city willing to report the location of my bag to the Google/Samsung servers for free. To improve the accuracy of the location updates, I would have to maintain a Google/Samsung device near my bag, which kinda defeats the whole point.
There are plenty of options, such as Tile, Marco Polo Tracking... You could throw in a cheapo device like a Raspberry Pi with a cellular module and battery. If you want to splurge, you can get something with a GPS and satellite comms connection that will work basically anywhere on Earth.
Alternately if you think the Airtag is a good fit for your purpose why not just just get a cheap used iDevice™, if all you want is the Apple Find thing? I will point out that two things here are at odds: wanting to do things on-the-cheap, vs wanting constant real-time location updates. If you can relax one or the other that makes it a lot easier. Perhaps you don't really need 120-second interval location updates? --Slowking Man (talk) 01:24, 18 January 2025 (UTC)[reply]
That said, in my observations, fast tracking is not really anything that's really the case much with Find My anymore as sometimes my device's locations will be reported as their location from 2-5 days ago with Find My refusing to update. (Note: I'm still on iOS 18.2 so it might be fixed in 18.2.1.) Even when it used to be fast, it would only ping when you opened Find My, and would not auto-update for 5-7 mins.

In Firefox (on MacOS) I sometimes accidentally hit a combination of keys that makes a new tab, same as the current tab, appear at the right.

Alt-↵ Enter with the address bar highlighted will open its contents in a new tab, which is often functionally a tab duplication. So maybe you wrangled a Ctrl-L, Alt-↵ Enter? (Sorry, not exactly sure what these map to on MacOS.) Emberfiend (talk) 09:08, 17 January 2025 (UTC)[reply]
