Hi Andrew, Hope you're well =)
Glad you're well. I look forward to your sequel. Hope the programming language learning goes alright)
Thanks for your comment; I was working on a few notes some time ago, but health issues (a heart attack) and a few other things have intervened.
Thanks; I've added it to my fix-up list. (hope you liked the book)
Mmm, thanks; I'd better take a look at this to see what I think... (but later)
