You need to start caring about a few things. Now.

Code style

Looking through code, you see all sorts of things. Some of them are good. Some of them are downright amazing pieces of code.

Some of them are horrible.

Some of them are so bad you feel your grip tensing around the keyboard and you have to restrain yourself so you don't snap the bloody thing in half.

They might be bad decisions. They might be caused by someone who didn't have the knowledge to make the proper decision. They might have been good decisions then, but terrible now.

But I don't care about those things.

I'm here to talk about code style. For example, what's wrong with this block of ruby from a style point of view?
