These really aren't that recent, but I just discovered them. They also aren't 'talks' (well, they were talks, but the talk itself was not recorded), but, instead, slideshows. Nevertheless I found them all interesting.

I've been using DBIx::Class recently. It's the first ORM I've ever used and it seems seemless. Here is a slideshow introducing DBIx::Class. Another detailing the much newer DBIx::Class::DeploymentHandler.

Plack is another interesting platform I've been unable to use as of yet. But here is a slideshow that has some very impressive example code.
