Software Cover Versions And Programming Licks

02 Sep 2012

The next time you’re trying to think of something you could put into code and you shrug of ideas because they’ve already been implemented, try this: Write a cover version of a piece of software.

Try to imitate software. A project you like, a project you use, a project that implemented the idea you just shrugged of. Imagine yourself in a software cover band and try your best to replicate it.

Why? It’s surely a waste of time, I hear you say. And if we’re talking about paid software development I fully agree. But consider yourself having a couple of hours to spare and you’re eager to write some code: covering a piece of software proves to be a great way to gain knowledge and become a better programmer.

I’ve been playing guitar for nearly eight years now and spent a great deal of that time learning and playing other peoples songs. Creatively speaking this is not as fulfilling as writing your own material and coming up with new, fresh ideas is certainly better than playing The Thrill Is Gone at a bar gig. But by doing covers you learn new chord sequences, new [licks](http://en.wikipedia.org/wiki/Lick_(music) ‘Licks (Wikipedia)), new tricks and probably discover something new you haven’t thought of yet. And once you’ve got a song down and can play it note-perfect, when your muscles remember how to play a difficult part without struggling, then comes the best part: you can have fun and play around with it. You can improvise over it, you can change it, you can disassemble and reassemble it and (this is most important bit) you can use those little tricks and ideas and incorporate them in your own material.

I’m not talking about copying here, I’m talking about learning solutions to problems and applying them when the need arises. Learning to play a Led Zeppelin song on guitar might sound dull since every guitar player on the planet knows how to play at least one of them. There is nothing left to prove. But there is still something left to be learned: when you’ve got the solo of Since I’ve Been Loving You down to the note, the next time your solo spot comes up and you want have a intense dynamic build-up, try to think of Jimmy Page and how he’d do it, which tricks he’d use.

You do this with software and programming too. I’ve been playing around with statsd a couple of weeks ago and I thought about implementing a stats collector in Ruby until I found out that it’s already been done. So I was about to shrug it of and do something else when I decided to do it anyway. Just for fun. Just to find out how to do it.

I wouldn’t have learned as much as I did in the last week about buffering, concurrency, streaming and UNIX sockets if I hadn’t tried it. And the best part? Whenever I got stuck, I read through the statsd or the batsd code to see how they solve a certain problem and I learned something new. Surely you learn something new too when trying to implement a piece of software that hasn’t been written before. But this is different: you already have solutions to problems to look at and learn from. And when facing the same problem you can learn about the problem and the solutions at the same time. This is a great way of learning software development, since you can’t fully understand and judge a solution if you don’t fully understand the problem you’re facing.

And once you know and understand different solutions to different problems you can then apply them in other situations. By trying to write software covers you get to know the problem and how a particular piece of software solved it. Or, as in my case with statsd and batsd, you start to understand different solutions to one problem. Doing this, you can learn a whole lot of new programming tricks and licks and use them whenever they fit.
