Typo in your PDF copy of Chapter 10?

In chapter 10 on page 258, the Bash shell code explanation says Counts the number of lines that end with 1, which indicates malignancy, but in fact, lines end with 1 doesn't mean malignancy. It means it's a nodule and it can be malignant or benign.

In the later section, you also have 0 for a candidate that is not an actual nodule, and 1 for a candidate that is a nodule, either malignant or benign. This is kind of confusing.

Yes, you're right, thanks for catching the error. I'll update the errata document to include this.
