Looking back on it, I probably have those blue O'Reilly books ( and Perl Cookbook https://www.oreilly.com/library/view/perl-cookbook/156592243... ) to thank for starting me off on my programming career and influencing so much about how I grew as a programmer. Very informative books and fun to read. What a great set of authors.

I now program almost exclusively in Python (it's good and interesting) and Java. But occasionally I fall back to Perl for something that is just so much simpler - almost muscle memory.
