On his blog Left On The Web, Stefan Koopmanschap lists the podcasts he's listening to. His selection contains both tech and non-tech podcasts.

I had sitting in travel not being able to do anything. Listening to music can help, but can end up also being frustrating. While I was working at Schiphol last year I got pointed to podcasts. Since then I've been really getting into listening to podcasts on my daily commute and it's been making the trip a lot more fun... and useful.

Here is a random collection of podcasts that I've been listening to in the past year and a half, on many different subjects. My main problem right now is that it's so many that I'm way behind on the episodes of most of these. Ah well, it's still quite good content.

Here are a few of my favourite podcasts:

North Meets South In this relatively young podcast Jacob Bennett and Michael Dyrynda talk about the things that make them tick.

Twenty Percent Time Daniel Coulbourne & Caleb Porzio weekly discuss a programming topic. They try to keep it to twenty minutes, but that doesn't always work out that way :-)

The Laravel News podcast Besides North Meets South, Jacob and Michael also run another podcast focused on all things happening in the Laravel ecosystem.

Full Stack Radio Adam Wathan & David Hemphill talk about how they are creating their products: Crondog & KiteTail

Voices Of The Elephant In this podcast Cal Evans interviews people active in PHP community. It's been a while since there was a new episode, but it's still worthwhile to listen to.

The Changelog Adam Stacoviak & Jered Santo weekly have a conversion with somebody from the open source community.
