Errata & Updates

We really checked everything in the book obsessively, several times at each stage of the book’s production, and on all three operating systems (Windows, Mac and Linux), but mistakes can slip through. Have you spotted one? If so, please send the details in an email to

Second edition: No problems have been spotted in the second edition, yet.

First edition: Errata for the first edition can be found here.

Software installation problems: If you’re having difficulty installing a piece of software, or are struggling to get a particular example to work, please visit the forum instead because it may be a problem with your computer setup rather than a mistake in the book.
