Notification of maintenance: In the next week we have to upgrade the servers due to increased demand. That may result in outages as we make the upgrades. Sorry for any inconvenience.
I screwed up and posted the working copy of the book on Bookapy. I didn't know until some readers sent me feedback. The new version is loaded and, in your bookshelf, if you purchased a copy. Thank you for the feedback and keep it coming.
