This post is part of the Classics Week(s) feature, which will run for three weeks while I’m off overseas. It’s the first of three posts from the early days of the blog, dug up from the archive and polished ’til good as new!
Ladies and gentlemen, allow me to share with you a tale of two photographers.
Back in the summer of 2010, my fiancée and I were featured in a piece for our local newspaper. The columnist wanted an image to accompany her content, and sent a photographer to our apartment to take a photo of me and my soon-to-be bride.
The photography session played out as I’d expected. Some nondescript ‘dude’ with a camera sauntered in, looked around the room for all of about six seconds, arranged a semi-interesting shot involving a mirror, snapped a few pictures and left. Took around ten minutes.
A few days later, the writer called back and asked if she could send over another photographer. Apparently the shot the boring fellow took was too similar to a shot the newspaper was running on another article â€” on the same day, in the same section â€” so they needed a different one.
The second photographer was Christopher Pike.
Christopher ran things a bit differently. After introducing himself, he spent a few minutes looking around our humble abode and the surrounding area. He then asked what my fiancée and I thought of a few potential shots, and started taking pictures.
We posed on our balcony. We posed on a bench. We posed near a wall, and then next to a fence. Every time Christopher noticed something that might make for a cool shot, he asked if we wouldn’t mind another photo.
After about an hour of this, he thanked us and left.
Like the first photographer, Christopher was a freelancer hired by the newspaper. Presumably, the two of them were each paid the same amount for their work. But while the former spent ten minutes taking a picture he had decided upon in advance, Christopher spent seven times that long experimenting and looking for the perfect shot.
What does this have to do with programming?
Just like photography, programming is a craft.
That first photographer, the one whose name I couldn’t be bothered to remember, was just in it for the job. The columnist wanted a cute photo of a young couple, so our unremarkable photographer snapped an equally (un)impressive shot, and left.
This is how unremarkable coders look at programming. You need a function that converts X inputs into Y outputs? Sure. Let me whip up a quick algorithm that does that. Done. What’s next?
Christopher, on the other hand, was there to take great pictures.
He was passionate, and he approached photography as a craft. Yes, the result was still just a photo to sell to a newspaper, but believe me when I tell you that’s not why Christopher is a photographer.
Here’s how I look at coding (and hopefully how you do too):
You need a function that converts X inputs into Y outputs? Ok. Let’s first consider the context, ask a few questions, then create a proper solution. Functionally, it may be the same as Joe-first-photographer’s solution, but a programmer that cares about his craft took the time to:
- Verify that a single function is in fact the best solution.
- Keep future maintenance and extensibility in mind.
- Write clear, reusable code.
- Add useful comments when necessary.
- Refactor the function to be as simple as possible.
- Switch spaces to tabs to match the existing code-base.
Which photographer would you rather hire?
Which programmer would you rather have on your team?
