Thou Shalt Rend Software and Religion Asunder
Steve McConnell, Code Complete Second Edition
There are numerous infamous religious wars in the world of programming. Windows vs. Unix, Windows vs. Mac, IDEs vs. text editors, Emacs vs. vi, Python vs. Ruby, where to put the curly brace, spaces vs. tabs, 2 spaces vs. 4 spaces; the list goes on ad nauseum. The fact that these arguments never end shows that there is no “true” answer. Usually it comes down to personal preference, which is fine. The problem comes when programmers become bogged down in the arguments, and begin to see their side as “the one true way”. Anyone using the other method is an infidel and must be converted or crushed. Of course, this is often just tongue-in-cheek banter, but all too often it goes further than this.
Most of my friends probably have a preference either way for Coke/Pepsi, and some have explained to me their reasoning. But none of them have ever tried to tell me that I’m drinking the wrong drink, because that would be silly (I hardly ever drink Coke or Pepsi, but that’s a moot point).
Alex Martelli wrote a fantastic essay about the differences between Ruby and Python on comp.lang.python. He makes a thorough comparison, noting what is shared and what is different. He also gives his opinion on why he prefers the Python way, while noting that it is only his opinion (speaking on implicit calling of functions vs. requiring empty parentheses: “I do understand why others would thing otherwise, even though I could hardly disagree more vehemently with them:-). “).
Now, I know there are a lot of enlightened programmers out there who already work in this way, so good work. But to all the others, have a look through the list of wars at the top of this post, and see whether you might be able to cross over to the dark side, however briefly, and try out your enemy for a bit. At least then you can give an objective argument about why you prefer one over the other (which always beats “x is teh suck”). Hopefully though, you’ll find that these things just aren’t worth arguing over.
