So on Saturday night after skiing, I had this urge to figure out, if I could actually make an almost useful app just with a few prompts of ChatGPT. I also wanted to make sure it doesn't just steal somebody else's code, so I tried something I assumed nobody has made yet: a sticky notes desktop app in Ruby. To my amazement it worked! Took maybe 30 minutes with some tests. I have never touched the UI framework gtk3 before! Thus the title.
