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.
Add a "Quack Overflow" memorial:
1 * * * * /usr/bin/mpg123 /home/username/Downloads/quack.mp3 &>> /dev/null
RIP 4/1/18 - 4/1/18
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.
