"Good Code Documents Itself" and Other Hilarious Jokes You Shouldn't Tell Yourself:

I didn't notice this story when it appeared on Hackaday just over a year ago. I'm well aware this has all the hallmarks of devolving into an emacs vs vi battle. Yet, the story does raise some interesting points about the different kinds of comments. That some comments are worse than useless and others can have great value. Without further ado, here's the introduction:

Code documentation - is there anything more exciting than spending your time writing extensive comments? If I had to guess, your answer is probably somewhere along the lines of "uhm, yes, everything is more exciting than that". Plus, requesting to document your code is almost like an insult to your well thought out design, this beautiful creation you implemented so carefully that it just has to be obvious what is happening. Writing about it is just redundant, the code is all you need.

As a result, no matter if it's some open source side project or professional software development, code documentation usually comes in two flavors: absent and useless. The dislike for documenting ones code seems universal among programmers of any field or language, no matter where in the world they are. And it's understandable, after all, you're in it for the coding, implementing all the fun stuff. If you wanted to tell stories, you would have chosen a different path in life.

This reluctance has even formed whole new paradigms and philosophies claiming how comments are actually harmful, and anyone trying to weasel their way out of it can now happily rehash all those claims. But, to exaggerate a bit, we're essentially villainizing information this way. While it is true that comments can be counterproductive, it's more the fundamental attitude towards them that causes the harm here.

In the end, code documentation is a lot like error handling, we are told early on how it's important and necessary, but we fail to understand why and instead grow to resent doing it again for that same old teacher, supervisor, or annoying teammate. But just like error handling, we are the ones who can actually benefit the most from it - if done right. But in order to do it right, we need to face some harsh truths and start admitting that there is no such thing as self-documenting code, and maybe we simply don't understand what we're actually doing if we can't manage to write a few words about it.

So let's burst some bubbles!

I found the rest of the story well worth the read. Highly recommended! I'll be the first to admit that the coding example has shortcomings. But it did serve as a concrete basis on which to launch the discussion.
