so... 9 years ago we had this super awesome codebase. 1 file, complete logic COPIED to be used in ui and service/daemon. I scrolled to the middle of the file and there was no source. it was out of bounds of my monitor to the right because of nested ifs. ok... what the fuck!! the worst part: I had to implement a new FEATURE into this mess. 2 days. I said it would not work as expected because the feature was not thought through. but project said let's gooooo! ok there I was, a junior with an impossible to implement feature and a codebase from hell. I've implemented something, all night long. next day it was the problem of the consultants. they called me, I told them why it's impossible that this would ever work, they understood and talked to the customer. he accepted the solution. WTF?! anyway, in those days I thought about quitting developing software as my daily job....
