Programming is fortunately one of those subjects where there's something objectively close to a correct/optimal solution. A trivial example is that there aren't very many sane ways to write a "Hello world" program, but this seems to hold for more complex tasks too. In fact, in my experience, the ones who cheat and get it wrong are the most obvious.

Unfortunately, the software industry also has plenty of literal tools who are far too trusting of what the computer says (or authority in general, but that's another rant...)
