Preface

If you've been a software developer for a long time, you have certainly participated in software conferences or developer forums and experienced many interesting conversations. They start out well with one of the developers describing a cool development process that he/she follows, and then another developer strikes with a cutting-edge technology or tool or a mind-boggling enterprise integration pattern that he/she works with. Each speaker attempts to outdo the last speaker. Old timers speak about ancient machines that had to be programmed with punch cards or switches, where they had only few bytes of RAM, or they start describing COBOL as a dynamic language that follows the Model View Presenter pattern. Ask them three questions: "How do you unit test your program?", "Can you alleviate high blood pressure by monitoring your pressure more often?", and "Have you ever maintained your own code?"
