 Debugging tools are wonderful when they are stable and available, but the printlining and logging are even more important. Debugging tools often lag behind language development, so at any point in time they may not be available. In addition, because the debugging tool may subtly change the way the program executes it may not always be practical. Finally, there are some kinds of debugging, such as checking an assertion against a large data structure, that require writing code and changing the execution of the program. It is good to know how to use debugging tools when they are stable, but it is critical to be able to employ the other two methods.
 
-Some beginners fear debugging when it requires modifying code. This is understandable - it is a little like exploratory surgery. But you have to learn to poke at the code and make it jump; you have to learn to experiment on it and understand that nothing that you temporarily do to it will make it worse. If you feel this fear, seek out a mentor - we lose a lot of good programmers at the delicate onset of their learning to this fear.
