I wondered if quack-overflow will be available outside of the 1st April jokes period (even if it's a hacky mean like activate it through the console etc…). Since rubber-duck-debugging is a technique I use a lot and promote among my colleagues I'd really appreciate this fun support.

    You just keep a physical rubber duck at your desk, and promote your colleagues to talk with it. Mar 31, 2018 at 21:16
  • I do, but having SO as a support makes it more serious and gives more credit to the method than I do. Mar 31, 2018 at 21:37
  • Usually the comment I see is "Have you asked the duck" ... lame

  • The duck might be a trick to fool us. Dont fall into the trick! Its April Fool today! Beware :) I mean the duck ask us to speak louder and we speak louder and louder and it shows just a fun message "Quack".. Apr 1, 2018 at 8:13

    Yes, on a web archive of a Stack Exchange site from April 1st, like here. Apr 1, 2018 at 9:02
  • @DonaldDuck - looks like web archive still links meta.stackexchange.com/content/Shared/quack.mp3 so the full duck experience won't be available Apr 2, 2018 at 17:58

All previous Stack Exchange April fools changes have disappeared the moment it is April 2nd everywhere in the world. This one is sure to suffer the same fate.

Sometimes the source code is disclosed after the event. If that happens you could host the duck on your own site.

    This time it’s set to run until April 3 UTC because April Fools itself falls on a Sunday this year. This might change once Monday actually rolls around, but at the moment that’s the plan.

    Source code is already available, it's mostly client side. And the server side part (if there's any) won't be sourced out as far as I can tell, @Adam can confirm. Mar 31, 2018 at 22:22

    @ShadowWizard Yeah, the server-side part is just access controls/date checks. The markup is rendered into the page and the rest is javascript.

    @AdamLear How do I know whether or not what you said about the date, is not an April Fool's joke? Mar 31, 2018 at 22:39
  • @Adam thanks. What about giving non minified version of the JS though? Mar 31, 2018 at 22:40

    @SonicWizard There’s only one way to find out.

    @ShadowWizard I’ll see what we can do. There’s really not much to it, though.

  • @Adam yeah, guess most work was done on designing the duck and those cool animations. :D Mar 31, 2018 at 22:46

    @ShadowWizard: cdn-dev.sstatic.net/Js/quack.en.js Mar 31, 2018 at 23:03
  • @IlmariKaronen this is minified version and is almost useless. One need to spend lots of time and efforts to decode it back to readable code. Possible, but hard to do. :) Mar 31, 2018 at 23:08

    @ShadowWizard: No it's not. It does start with a minified copy of the sine-waves script, but you can find the unminified version of that on GitHub. The rest of the code on cdn-dev is not minified. Not that there's much of it. Mar 31, 2018 at 23:13
  • @Adam also, who is the developer behind the Duck? Is this you? :) Apr 2, 2018 at 6:32
  • @AdamLear You didn't mention the "year" (in your 1st comment). fingers crossed you mean 2018 ... PS: this answer is clearly not correct ... i.e. the "This one is sure to suffer the same fate." part of it (anywhere in the world it is at least April 2 already ...). Apr 2, 2018 at 11:44

    @ShadowWizard Yes, with design stuff done by Aaron Shekey.

Yes, via a mirror

    This should be the accepted answer!!!!! Dec 6, 2021 at 12:26

Add a "Quack Overflow" memorial:

crontab -e

1 * * * * /usr/bin/mpg123 /home/username/Downloads/quack.mp3 &>> /dev/null

RIP 4/1/18 - 4/1/18

enter image description here



It depends upon what SE designer engineers want to do. If they want to keep it there, they can do. If they want to delete it after first april, they can do that too.

From my side I would say I liked the concept of "Rubber-ducking" (Think-out loudly wikipedia link); although usually personally I think out not "loudly" but more of a visually (you may term it "brightly" or "colourfully" or "darkly" or whatever you wish), so you may add a scribble pad or modelling clay or a virtual 3-dimensional object too.
