in C Plus Plus, programming, ruby

stop trying to show how smart you are

Sitting feeling bright and somewhat giddy with my own self confidence I decided to dust down my copy of “C++ Template Metaprogramming” by David Abrahams and Aleksey Gurtovoy. Thinking I really need to be the master of something and further thinking C++ template programming was that “thing”. I approached the task with some gusto for at least a few days hours minutes, however, as with most advanced study you really have to be willing to dedicate your life to it. It’s never long before the inevitable gloom of reality sets in and you realise that this is more than an afternoons work. Without much control your brain starts telling you that there are much more important things you could be doing. Thankfully for everyone else on your team you stop and decide that it’s just not worth it.

The fact is that writing code that only those who have decided to dedicate a fair chunk of their life to is never going to be the right choice. There is nothing worse than trying to understand code like this. There are times where it pays to be smart, like when you have a better (much) faster algorithm, or doing something saves you hundreds of lines of code. But most of the time you see this kind of code it’s people just trying to prove how smart they are.

Now C++ is not alone in this. Ruby has exactly the same problem – you can get stuff happening as if by magic. I could be wrong but I imagine most people read code from top to bottom, working line by line, they don’t expect code to be auto generated or happen as some elaborate method_missing technique. Sure I can maybe relax my vitriol for those building frameworks where things are being used in some generic unknown context. However the vast majority of applications out there don’t have to deal with these problems. The biggest problem these applications face is that the developers creating them want to architect some elaborate framework to fit a very specific use case – it almost makes me cry. I’m not sure why as a profession we don’t revel in an approach that oozes simplicity. This is certainly what the smartest developers I’ve working with have always managed to do.
