random entropy

The ability to see the code you’re writing today and its possible evolution through time is something you can focus on learning, but it also grows with experience. It’s one of the things that makes a great hacker’s code subtly better than a newbie’s code – both start writing simple code that addresses the problem directly, but the newbie makes all sorts of small structural mistakes that get in the way of the code’s growth, whereas the hacker knows when it’s time to turn this set of functions into a class, or to abstract out this behaviour, and has already prepared the way for doing so. The effect is to make programming look effortless again, naturally flowing from the simple into the complex.
