Drieux and others mentioned this book a couple of weeks ago. I just
got a copy and spent yesterday afternoon exploring several parts of
interest. I'm impressed:
For one thing, it really is for novice/intermediate Perl folks.
There is a *lot* of code in the book, and one of the neatest features is
that each and every example is accompanied by a line-by-line explication of
what each line of the program accomplishes. This is valuable because much
of the CPAN code and OO-ish syntax is new to me, and just seeing it in a
program without explanation is pretty opaque.
The book is incidentally a pretty good introduction to CPAN and the
CPAN shell. So much of the network code exists in CPAN modules that you are
forced to negotiate CPAN in order to get the work done. Mr. Stein is a good
guide to getting what you need from CPAN.
There are a couple of caveats: all of the code is based on 5.003.
I'm running 5.8, and have had to make a few concessions and adjustments here
and there. (No warnings!). Also, it's pretty Unixy. The first script I
tried did not in fact run properly on Windows, although it ran fine on
FreeBSD.
Finally, you should note that some of the programs in the book could
get you in trouble with your local network admin. There are programs here
that could set off intrusion alarms or even bring down applications if you
make certain mistakes.
All in all, a good investment I think, and my thanks to the list for
recommending the book!
