Hi, I’m just getting started with the book, so I came here looking for source code and errata.
Hopefully you will fill in a cross reference of pdf page numbers to paper page numbers, so I can find (and fix) whatever was found in the “other” version.
One thing that is missing (or am I just too lazy?): on page 5 (paper version) it has links for online refreshers, tutorials and examples. It would be nice to have those links here, so A) the reader doesn’t have to type them in, and B) you could update them if any of those sites change their structure.
