Code Reading: The Open Source Perspective (PDF/EPUB Version)

If you are a programmer, you need this book.

• You’ve got a day to add a new feature in a 34,000-line program: Where do you start? Page 333
• How can you understand and simplify an inscrutable piece of code? Page 39
• Where do you start when disentangling a complicated build process? Page 167
• How do you comprehend code that appears to be doing five things in parallel? Page 132

You may read code because you have to–to fix it, inspect it, or improve it. You may read code the way an engineer examines a machine–to discover what makes it tick. Or you may read code because you are scavenging–looking for material to reuse.

Code-reading requires its own set of skills, and the ability to determine which technique you use when is crucial. In this indispensable book, Diomidis Spinellis uses more than 600 real-world examples to show you how to identify good (and bad) code: how to read it, what to look for, and how to use this knowledge to improve your own code.

Fact: If you make a habit of reading good code, you will write better code yourself.
