RoR is too much magic for me. Getting started with any new code base is such a pain that I never want to do again. As a manager, I’ll avoid any job post that mentions Ruby. I have maintained projects written in Delphi, Centura, Java, C#, PHP and none of them even come close to the pain of RoR. Java and C# are notorious for ceremonial interfaces but that’s nothing compared to trying to figure out RoR automagics.
If the price I saw when I picked an item is different to what I pay at the counter, I’ll never be back at that place again, even if it means I’m paying less.
