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.

I have come up with an analogy that should make the basic principles of software design understandable to everybody. The great thing about this analogy is that it covers basically everything there is to know about software design.

Imagine that you are building a structure out of lead bars. The final structure will look like this:

Sane Software Design

You have to build the structure and put it up at a certain location, so that people can use it for something.

The lead bars represent the individual pieces of your software. Putting it up at the location is like putting your software into production (or sending it out to your users). Everything else should be fairly clear as to how it translates to software, if you think about it. You don't have to translate everything to software in your mind as you read, though. Everything should be quite clear if you just imagine that you really are just building a structure out of lead bars.

The Wrong Way
