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 1. Before You Begin…

One of the major goals that I have with researching software design is the hope that we can take people who are "bad programmers" or mediocre programmers and, with some simple education and only a little experience, bring them into being good programmers or great programmers.

I want to know – what are the fundamental things you have to teach somebody to make them into a great programmer? What if somebody's been programming for years and hasn't gotten any better – how can you help them? What are they missing? So I've written quite a bit about that in this book, particularly in Part Seven -Suck Less.

However, before somebody can even start on the path of becoming a better software developer, one thing has to be true:

In order to become an excellent programmer, you must first want to become an excellent programmer. No amount of training will turn somebody who does not want to be excellent into an excellent programmer.

If you are a person who is passionate about software development – or even just somebody who likes being good at their job – it may be hard to understand the viewpoint of somebody who simply doesn't want to get any better. To fully grasp it, it can be helpful to imagine yourself trying to learn about some area that you personally have no desire to be great in.

For example, although I admire athletes, enjoy playing soccer, and sometimes enjoy watching sports in general, I've never had a desire to be a great athlete. There's no amount of reading or education that will ever turn me into a great athlete, because I simply don't want to be one. I wouldn't even read the books in the first place. If you forced me to take some classes or go to some seminar, it would leave my mind as soon as I took it in, because I would simply have no desire to know the data.

Even if I was playing sports every day for a living, I'd think, "Ah well, I don't have any passion for athletics, so this information simply isn't important to me. Some day I will be doing some other job, or some day I will retire and not have to care, and until then I'm just going to do this because they pay me and it's better than starving."

As hard as this can be to imagine, that is what happens in the minds of many "bad" programmers when you tell them how or why they should write better code. If they don't sincerely want to be the best programmers that they can be, it does not matter how much education you give them, how many times you correct them, or how many seminars they go to, they will not get better.
