We hope you're enjoying our book, Data-Driven Security!
You can find all the source code and official errata over at the publisher's site.
We'll be primarily posting book-related updates—our own/your-submitted errata/code fixes, IPython Notebooks, Rmd views, coupon codes, book signings, etc—to the DDS Book area, saving parabook ramblings for the blog and podcast.
If you find a mistake, have a question about something in the book or just want to say "Hi!", don't hesitate to drop us a note on twitter or shoot us an e-mail.
