I gave a presentation last week at Bluehost about using functional programming techniques to overcome some of the common quandaries in procedural codebases.

Here’s the blurb:

Functional programming is the oldest but least well known of the three major programming paradigms. While it has a reputation for inscrutability, many of its tenets can be applied to both procedural and object-oriented paradigms to reduce complexity and create cleaner code. In this workshop we’ll get a taste of functional programming in Perl and apply the techniques we learn to refactoring and removing common procedural anti-patterns.

I presented at our Salt Lake Perl Mongers about using Docker to isolate dependencies in your Perl applications.

I gave a talk at OpenWest about Perl’s AnyEvent module and some of its primitive operations.

I gave a presentation at OpenWest about Perl dependency isolation using perlbrew and plenv + carton:

Given a multi-level deep hash reference:

my $conf = {
    bucket => {
        list => {
            h    => 'help me',
            _sub => sub { say "something" }
        }
    },
    file => {
        upload => {
            h    => 'help me too',
            _sub => sub { say "else" }
        }
    }
};

We want to remove all of the _sub keys and put them in a separate hash reference with the same structure. This does that:
