The Perl community on LinkedIn is fascinating. It’s a great way to see how Perl is perceived and used outside of the echo chamber. And that’s a real eye-opener. Here’s an example. Every few weeks (it seems) someone asks for advice on Perl books.At that point, a few people will jump in with sensible suggestions. […]

Why Corporates Hate Perl
This is a reprint of an old blog post. A few years ago I was writing blog posts (semi-)regularly for O’Reilly. This is the one that probably got the most feedback. I’m reprinting it now because a) it’s pretty hard to find on the O’Reilly site and b) it’s relevant to a couple of conversations […]

BEGIN failed--compilation aborted. |

CGI.pm vs Templates
I’ve just been involved in a discussion on LinkedIn that I thought deserved a wider audience (I have no idea how well that link works if you’re not a member or or logged in to LinkedIn). A couple of days ago, someone asked for advice on the best way to include HTML in a Perl […]

What is Modern Perl?
I wrote an article for Josette called “What is Modern Perl?” In it, I talk about the different things that people might mean when they talk about Modern Perl and why it’s well worth buying a copy of the new edition of the camel book. After a gap of twelve years, a new edition of […]
