Do you remember back in school when you learned stuff you certainly would not need anymore in your future life? I thought the same thing when we programmed things in Delphi (those things actually were quite interesting, though). After Phil poked me once again yesterday, I finally decided to fix long-standing bug #145. So, guess what, the setup system we use (InnoSetup) is not only written in Delphi but also allows custom Pascal Code to be executed during setup. So this is what I came up with, and it would certainly have taken me some more hours if I did not know Delphi before.
I wonder however whether I will have to use Java for some real-world application one day. I would be nearly as good prepared as I was for the Delphi task.
