I have ignored my MacBook Pro for a few months. Now my iTunes and Rhythmbox music libraries are out of sync. The Rhythmbox library includes a handful of Ogg Vorbis files. Because iTunes does not support Ogg by default, I will use FFmpeg to convert those files to MP3. For the sake of novelty, Perl 6 is the glue language for the task.

Thought I’d share TOKUHIROM’s cpan-outdated tool, which simplifies the task of keeping your installed Perl 5 modules up to date. It simply lists available updates to Perl modules you have installed. That functionality is available in the CPAN shell with the
rcommand, but it is hard to beat the convenience of the cpan-outdated command line tool.

I had a clever idea a couple months ago: to write a blog post detailing how to find recursively find duplicate files in a folder. My technique was good enough: track file sizes, find files that had the same file size and MD5 hash, and display the resulting list. It wasn’t foolproof, but it showed some thought. After spending a little too much time on the post, I realized I had never checked CPAN. Of course there is already a module to handle that exact task.

YAPC::NA, the Yet Another Perl Conference for North America, just happened. I didn’t go. Since I didn’t go, I want to compile everything I can find about the conference in one place. Videos, slides, blog posts, whatever.

I have been dabbling a lot with Moose, a solid framework for object oriented programming in Perl. It is remarkably powerful and has transformed the way I look at Perl OO. It is also different enough from object oriented programming in other languages that I needed to create a section for it on coolnamehere.

Parrot is more than just PIR and PASM. I’m not talking about the ability to use languages like Rakudo written for the Parrot virtual machine. I am also not talking about the ability to write your own language. Both of those are quite nifty, of course. It is fair to say that those two items are probably why you are experimenting with Parrot in the first place. However, the Parrot distribution also ships with an extra language: NQP.

Nice work! You have begun to learn Perl by writing a complete program which gets input from a user and prints output including a modified version of their input. Yes, there is much more to learn, but you have dipped your toes into the pool. Now you can go out there and start learning about the huge and wild world of Perl programming!

This page once contained many links to Perl 6 information as the design notes were being assembled for the newest revision of this language. Those links are painfully out of date now. I’ll streamline instead with a few core ideas:

Having a program that displays the exact same message every time you run is nice when it comes to being consistent, but not so entertaining as a program. “What does it do?” “It prints out my name.” “Oh.” Let’s make things a little more interesting. We could change the value of
$namein the code, but it might be a little tiresome to do this before showing it to each new person. How about making the program ask for a name? User interaction - a neat idea.

Let’s admit it. Perl is everywhere. It powers most of the Internet, in one form or another. What? Your site doesn’t use Perl and CGI? Well, what about the administrative scripts that keep it running smoothly when everyone is snug in their beds? Even a fair chunk of Microsoft IIS servers rely on Perl for administrative tasks. I’m not saying that Perl is being used on every site on the Internet, including yours. I’m saying that Perl is probably being used on any random site you happen to look at on the Internet, including yours.

What can I say about Perl? I’ve had very little to talk about it on this site over the years, despite the fact that I use Perl on an almost daily basis. It’s not as cute as Ruby, or as clean as Python, but it’s always there. There have been numerous projects that are just plain easier in Perl. I can’t explain it.
