Understanding Software

By: Max Kanat-Alexander

Overview of this book

In Understanding Software, Max Kanat-Alexander, Technical Lead for Code Health at Google, shows you how to bring simplicity back to computer programming. Max explains to you why programmers suck, and how to suck less as a programmer. There’s just too much complex stuff in the world. Complex stuff can’t be used, and it breaks too easily. Complexity is stupid. Simplicity is smart. Understanding Software covers many areas of programming, from how to write simple code to profound insights into programming, and then how to suck less at what you do! You'll discover the problems with software complexity, the root of its causes, and how to use simplicity to create great software. You'll examine debugging like you've never done before, and how to get a handle on being happy while working in teams. Max brings a selection of carefully crafted essays, thoughts, and advice about working and succeeding in the software industry, from his legendary blog Code Simplicity. Max has crafted forty-three essays which have the power to help you avoid complexity and embrace simplicity, so you can be a happier and more successful developer. Max's technical knowledge, insight, and kindness, has earned him code guru status, and his ideas will inspire you and help refresh your approach to the challenges of being a developer.

Chapter 37. The Secret of Fast Programming: Stop Thinking

When I talk to developers about code complexity, they often say that they want to write simple code, but deadline pressure or underlying issues mean that they just don't have the time or knowledge necessary to both complete the task and refine it to simplicity.

Well, it's certainly true that putting time pressure on developers tends to lead to them writing complex code. However, deadlines don't have to lead to complexity. Instead of saying "This deadline prevents me from writing simple code," one could equally say, "I am not a fast-enough programmer to make this simple." That is, the faster you are as a programmer, the less your code quality has to be affected by deadlines.

Now, that's nice to say, but how does one actually become faster? Is it a magic skill that people are born with? Do you become fast by being somehow "smarter" than other people?

No, it's not magic or in-born at all. In fact, there is just one simple rule that, if...
