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.

Or spending some extra time putting some polish on your features and UI so that when the product is released, users are actually happy with it. Not adding features that you don't want to maintain, if they're not important enough – that's another one.

Remember that Mozilla ( did poorly for years, only to finally start gaining dominance in a market that Netscape had lost, because they had a long-term plan. Granted, Mozilla made some decisions early on that caused some things to take longer than they should have, but they still won out in the long term, despite failing in the short term.

Of course, it can be hard to convince people that your long-term plan is right, sometimes, because it takes so long to show results! When I started refactoring Bugzilla ( in 2004 there was pretty...
