If left alone, the morse code produced spells "WHAT" (.-- .... .- -) [[User:Ezist|Ezist]] ([[User talk:Ezist|talk]]) 22:50, 1 April 2021 (UTC)

I'm early enough that there isn't a summary yet, and I'm not confident enough to start one, so I'll just drop my thoughts. If you click the checkbox repeatedly, at some point it starts playing Morse code. Presumably, there are a whole lot of different sequences. So far, I've gotten .- - .-- .... (which translates to ATWS; no idea what that means) and ..... (just 5, I think). Meanwhile, the mouseover text is ... --- ..., which is SOS. Any thoughts? What other sequences are there? Or am I totally missing something? (Edit conflict. Looks like Ezist has another one.) [[User:Aerin|Aerin]] ([[User talk:Aerin|talk]]) 22:56, 1 April 2021 (UTC)
: I got something like ATWS at first, but that's just cause I misheard one of the letters, and misinterpreted where the word started/ended. [[User:Ezist|Ezist]] ([[User talk:Ezist|talk]]) 23:03, 1 April 2021 (UTC)
:: Oh yes, you're right - what I was hearing ''was'' just WHAT. When I put it into a translator, I must have mistyped .... (H) as ... (S). [[User:Aerin|Aerin]] ([[User talk:Aerin|talk]]) 23:58, 1 April 2021 (UTC)

Wait, sorry, I'm back. It apparently has to do with user input. No idea what I pressed to get those results lol. [[User:Aerin|Aerin]] ([[User talk:Aerin|talk]]) 22:57, 1 April 2021 (UTC)

Just a note, but a Morse code legend as well as translations of your input and the website's output are available in the console in browser DevTools. Helpful for those that don't know Morse. [[User:Toadtoad|Toadtoad]] ([[User talk:Toadtoad|talk]])

It looks like Samuel Morse died on April 2, 1872, so that might be why this comic appears today. [[Special:Contributions/162.158.212.218|162.158.212.218]] 23:07, 1 April 2021 (UTC)

"Hi" returns [.... . .-.. .-.. --- -.-.-- / .- -. -.-- -... --- -.. -.-- / --- ..- - / - .... . .-. . ..--..] "HELLO! ANYBODY OUT THERE?" [[User:Piano|Piano]] ([[User talk:Piano|talk]]) 23:09, 1 April 2021 (UTC)

a sequence of repeating "T", or at least more than one "E" [ - - - ] or [ . . . ] will respond back the same sequence, just one "E" will give "WHAT" [[Special:Contributions/172.68.25.253|172.68.25.253]] 23:18, 1 April 2021 (UTC)

"QTH" gives "QTH ARES VALLIS". "QTH" is a code used to ask for position, and Ares Vallis [https://en.wikipedia.org/wiki/Ares_Vallis is a place on Mars.] [[User:Ezist|Ezist]] ([[User talk:Ezist|talk]]) 23:27, 1 April 2021 (UTC)

"CHECK" replies "MATE." "CHECKMATE" and "MATE" each reply "WHAT." [[Special:Contributions/162.158.126.146|162.158.126.146]] 23:34, 1 April 2021 (UTC)

The js: has anyone tried viewing the JS? There seems to be a file that is just filled with undecipherable Morse. Can anyone interpret this? Just press f12 and look for comic.js or morse.js [[Special:Contributions/162.158.62.161|162.158.62.161]] 23:35, 1 April 2021 (UTC)

I tried decoding it. Certainly looks like something binary encoded into text. [[Special:Contributions/162.158.183.153|162.158.183.153]] 23:36, 1 April 2021 (UTC)

Adding onto that, what does the ';D' in .split(';D') (at the very end of morse.js) do? AFAIK it's not a special character in JS

morse.js decodes comic.js into the following script: [https://pastebin.com/XcHV4Z5h] (Also, pretty sure the .split(';D') is just an emoji - it results only in an array of 1 element, so no splitting really occurred.) [[Special:Contributions/108.162.219.78|108.162.219.78]] 23:52, 1 April 2021 (UTC)

running window.BeepComic.hurryUp() in console gives you immediate response in logs, without waiting for all the beeping to cease

Ah so that's where that script comes from [[Special:Contributions/162.158.183.153|162.158.183.153]] 23:40, 1 April 2021 (UTC)

`BeepComic.send(morse.encode('sudo make me a sandwich'))` <-- convenience, in addition to the hurryUp --rcombs

Does someone else get this uuid DB334AAB-92A1-11EB-8001-8C16454FB02A? [[Special:Contributions/162.158.238.228|162.158.238.228]] 23:42, 1 April 2021 (UTC)
: Yep, that's what I get too. [[Special:Contributions/172.68.132.239|172.68.132.239]] 00:29, 2 April 2021 (UTC)

Audio does not work on Safari as of right now - however, inputting `const AudioContext = webkitAudioContext;` into the browser console before unmuting will allow audio to work on Safari. May want to note this as a 'fix' for the experience? --[[Special:Contributions/162.158.63.6|162.158.63.6]] 23:44, 1 April 2021 (UTC)

In addition to muting/unmuting, BEEP and MUTE reply CQM (I can't find a reference to what that means). [[Special:Contributions/162.158.126.146|162.158.126.146]] 23:51, 1 April 2021 (UTC)

The statements at line 458 of the gist mentioned earlier seem interesting.
handleAction(text) {
if (text.startsWith('//')) {
this.client.open(text.substr(2));
}
}
: Nevermind, it was just how the response to "dir" opened links) [[Special:Contributions/172.68.189.101|172.68.189.101]] 23:52, 1 April 2021 (UTC)

Parsed the JS (morse obfuscation, weird) and cut this small bit out:
e = await fetch(`/2445/morse/.../${morse.encode('pog')}`);
f = await e.text();
[state, ...respMorse] = f.split('/');
morse.decode(respMorse.join('/'));
Use this if you'd like to play around with inputs. (replace pog, obviously) :) [[User:Ezist|Ezist]] ([[User talk:Ezist|talk]]) 23:53, 1 April 2021 (UTC)

No need to document UniXKCD here, there's already [[UniXKCD|a page for that]]. --rcombs

I got a different response for FORTUNE, it just tells me "OPEN ME" maybe Fortune gives multiple possible answers depending on luck, IP or something else, like a fortune cookie can have different answers inside it? [[Special:Contributions/141.101.104.81|141.101.104.81]] 00:19, 2 April 2021 (UTC)

For me FORTUNE responds with "OPEN ME", then I send OPEN, it responds with "YOUR DREAMS ARE NEVER SILLY DEPEND ON THEM TO GUIDE YOU" [[Special:Contributions/141.101.96.40|141.101.96.40]] 00:31, 2 April 2021 (UTC)

For me CHECKBOX responds with RADIO BUTTON and vice versa. Also, putting in a number doesn't seem to redirect me, but 11 does respond with "HUH"--[[User:Yodofrna|Yodofrna]] ([[User talk:Yodofrna|talk]]) 00:46, 2 April 2021 (UTC)

FORTUNE is a reference to the Unix 'fortune' program, but responses seem to be consistent for each user and not randomized like the Unix version. Use of a VPN confirms that responses are randomized by IP address. Sending OPEN only returns a fortune if it is sent immediately following FORTUNE.

It appears that unknown inputs produce WHAT, NOT FOLLOWING, SAY AGAIN, TRY THAT AGAIN, COME AGAIN, HUH depending on some properties of the input text. [[Special:Contributions/141.101.96.40|141.101.96.40]] 00:57, 2 April 2021 (UTC)

FORTUNE gave me "DO NOT LET AMBITIONS OVERSHADOW SMALL SUCCESS". Should we add something on the page to list all the fortunes we've found?

XKCD now returns "A CROSS THREE LETTERS". What could that mean? [[Special:Contributions/172.68.132.239|172.68.132.239]] 01:22, 2 April 2021 (UTC)

This isn't as convenient as the other in-browser console solutions, but I had fun quickly whipping up a script for NodeJS to query the Morse server and quickly get a response. https://github.com/realToadtoad/xkcd-checkbox-query [[User:Toadtoad|Toadtoad]] ([[User talk:Toadtoad|talk]])

1888: Still in Use

2017-09-11T22:10:32Z

Toadtoad:

{{comic
| number = 1888
| date = September 11, 2017
| title = Still in Use
| image = still_in_use.png
| titletext = 'Which one?' 'I dunno, it's your house. Just check each object.' 'Check it for *what*?' 'Whether it looks like it might have touched a paper towel at some point and then forgotten to let go.' '...' 'You can also Google to learn how to check which things are using which resources.' 'You know, I'll just leave the towel there and try again tomorrow.'
}}

==Explanation==
{{incomplete|Rough draft, can still use elaboration. Seems like there are two paragraphs more or less stating the same...? Do NOT delete this tag too soon.}}

Cueball is trying to remove the trash bag from his garbage can. However, the trash refuses to let him do so, citing that a paper towel in the trash is being used by some object in his home.

By itself, the comic is patently ridiculous; it is meant as a reflection of a common problem in computer use, specifically that of removing storage devices. If a file currently stored on a storage device is still open, the operating system will normally refuse to perform the "safely remove" function on that device. However, the operating system gives no indication of which application(s) have open file(s), and in addition, occasionally the system will falsely flag a file as still being active; this frequently happens if the user closes a file after triggering the "safely remove" function but before the alert comes up. This is frustrating for users, as they have little indication of the next step in removing the device. (Newer versions of Windows alleviate this problem somewhat for flash drives by adding a "Continue" button to the still-in-use dialog box; pressing "Continue" forces Windows to perform the "safely remove" function and unmount the drive even if one or more files on it are still in use.)

This comic may actually be a reference to the fact that one cannot delete a file in Windows while it's being used by a program, and Windows will also not tell the user which program it is, rather than the above explanation.

The title text may be a reference to a simple solution to these sorts of problems: Wait a while, perhaps overnight, and see if the (unknown) application(s) close the open file(s). Alternatively, the user can shut down the system to make absolutely sure that nothing is using anything, and then remove the storage device. In some situations, this is the ''only'' way (at least in Windows) to safely remove an external hard drive from a computer.

Also, the title text may refer to the typical "solution" to the file deletion issue: waiting it out. Sometimes, while trying to delete the file, it could get so frustrating that many give up until the next day, hoping it'll fix itself.

This comic draws parallels between the act of emptying a physical rubbish bin and performing garbage collection on a filesystem, iconically represented by Microsoft as the emptying of a virtual wastebin on the desktop. It also may refer the growing trend of Internet of things, which is a concept that enables everyday objects to collect and exchange data. Sometimes when attempting to delete files the software may still have the file marked as in use, because the file is still marked as open by at least one process. The software will therefore prevent its deletion. This may be correct behaviour, as in when a document is still being worked on in a program, or it may happen erroneously, perhaps because the program has not closed the file properly, maybe because of incorrect behaviour. The user is then required to find the cause of the problem and rectify it before the file can be deleted. This may be difficult if the user is not familiar with the file in question, or the program that would have used it.

In the case of the physical bin, the absurdity of this is highlighted by imagining that a paper towel is still locked as "in use" and that the rubbish bin won't allow it to be taken out for final disposal until the household object that was "using" the towel has been identified.
