Key to Icons

There are several different themes running throughout this book. The important ones are delineated by their own icons, as follows :

FANGS  

The meaning of Fangs (the slippery slope serpent ) should become clear after reading Chapter 3. Most chapters end with a summary of certain high-risk XP practices. Look for the Angry Fangs icon.

SOLUTION  

But it s not all doom and gloom. We also show how to reduce risk in XP. Fangs gets, well, defanged.

Karl Marx  

As we discuss in Chapter 4, certain Extremo quotes define XP in almost Marxist terms. These get a Karl Marx icon.

GROUCHO  

Then there s the other Marx. Extremo quotes that we feel to be particularly special or outrageous get awarded a Groucho.

SATIRE WARNING

The book is filled with dry humor and sarcasm, but some parts are outright satirical. This icon delineates what is satire and what is genuinely XP.

 

VoXP

We also provide some real-life anecdotes from people who have worked on XP projects. You d be forgiven for thinking that some of this stuff is satire, so the Voice of eXPerience (VoXP) icon helps to set these stories apart from the real satire.

 

Light Bulb  

Every now and again we encounter some circular logic in the Extremo world. If it s dark, just look for the light bulb. But then if there s a light bulb, it wouldn t be dark, right?

HYPE!  

Quotes that we feel to be particularly hype inflated, if they weren t already awarded a Groucho, get our ultrashiny, new-and-improved Hype! icon.
