Although the author would highly recommend the reader to sequentially go through the entire book, for the hasty learner, each chapter from Chapter 3 onwards is a stand alone exercise with a link to the source code at the end of every chapter. The link can be found just before the Summary subsection. All the code scripts used in this book are available from this Github folder.
For the images, they are available here.
Finally, this book is also available as a Portable Document File (PDF) here. For convenience purposes, this book is better read as a web version available here. This is because the web version does not clip long code along the page margins as is the case with the pdf.
