Clean Code

Introduction

Writing clean code is like riding a bike, you can study physics of it, but still fall down the first time you try to do it
Programming languages will be created with higher abstractions, and more specific languages related to domains we work will be created(a+), but that doesn’t mean programming will be a lost art. We can’t create machines that do what we want. We can only create machines that can do what we say.
