I made a rubber duck that floats in my IDE and physically panics when my build fails
Classic rubber duck debugging, only now the duck is real and judges me first.
It floats in the corner of your editor, calmly breathing as long as everything is fine, and panics as soon as the build fails. You can message it to "explain your error or idea," and it simply nods without judgment, nodding its head in agreement with any idea. It doesn't talk, and doesn't fix anything. That's the whole point.
It's called Rubber Duck Buddy, and it's free. The link in the comments to this post didn't get caught by the spam filter.
I created it simply because I wanted to. I have no regrets.
