DRY Career Advice

You’re probably familiar with Dave Thomas and Alan Hunt’s Don’t Repeat Yourself (DRY) principle first discussed in their book The Pragmatic Programmer. Broadly speaking the DRY principle can be interpreted as don’t implement the same functionality twice within a given system. Or doing the same thing two different ways within a given process.

We’re accustomed to applying the DRY principle to our designs and implementations, but what about our careers?

To paraphrase an infamous interview question what do you see yourself doing in 5, 10, 15, or 20 years? I know you still want to be programming at some level. That’s why you’re reading this blog: you’re passionate about programming and creating software. You love it. You seek to continually improve your craft. You’re going to continue programming until you retire. Even then you won’t stop and will continue programming until you expire!

Many of us are in this passionate programmer category. But we’ve also dodged the question. Given our nature and passion for programming it’s easy to say we’re going to be programming 20 years from now. It’s much more difficult to say what we’re going to be programming.

I’m not talking languages and tools – the things you’ll be programming with. I’m not talking about computers, clouds, processors and memory – the things you’ll be programming on or for. We can be sure these things will change, in some ways we can’t imagine, over the course of the next 20 years.

I’m talking about what kinds of systems will you be creating? The same kinds you’re creating today? Really? Twenty years of creating the same kind of software? That sounds pretty boring. It’s also potentially career limiting. Not to mention how do you really improve your craft when you’re recreating the same thing over and over again?

Working in industry verticals or niche markets is OK. But you don’t want to find yourself creating the umpteenth accounting system 20 years from now and trying to console yourself that it’s somehow different because the implementation language is different. Or the IDE you’re using is different. Or the type of machine it runs on is different. It’s not different. It’s the umpteenth accounting system you’ve created.

If you really want to spend an entire career creating software then I have one simple advice: Don’t Repeat Yourself. Don’t create the same system twice.
