Open Source Musicians Podcast: Although I don't do much with audio production these days I still enjoy listening to it and hoping that one day I'll have time to get back into it. (https://opensourcemusician.libsyn.com/rss)
Linux Outlaws: May it rest in peace. This is the podcast that got me started in Linux. Without it I would still be using Macs....shudder. (https://feeds.feedburner.com/linuxoutlaws)
The Mindrobbers: This show is run by a writer from my gernal area named Scott Carelli. I orginially heard of him through Podculture. I've followed his various podcasts for many years and this is the most recent incarnation. Although sometimes I don't always agree with his opinions I do always look forward to hearing them.

The Doctor's Companion: Another podcast by Scott Carelli and gang. Good American centreic view of Doctor Who, another of my favorite shows. (https://www.thedoctorscompanion.us/?feed=rss2)
The Babylon Podcast: This show isn;t in production anymore, but if you are a fan of Babylon 5 (which I am) this is a great show that breaks down each episode, and interviews many of the stars from the show. (https://www.babylonpodcast.com/category/shows/feed/)
Hiyaa Martial Arts Podcast: Must listening for martial artists (especially of the chinese martial arts persuasion). There are very few good martial arts podcasts out there that are not style specific. This fits the bill. One of the host practices the same style of kung fu that I do (although through a different branch of the family tree) and it's nice to see that perspective on other arts.

Unfilter: Jupiter Broadcasting's version of No Agenda. I used to listen to No Agenda but I find that it has become too long, and they tend to go off the deep end on some of their annalysis in my opinion. I find Unfilter to be a little more grounded, and it's an hour and a half once a week. I'll still listen to No agenda from time to time, but not regularly since I found this.

This Week in Science: A good weekly roudtable science news podcast. Used to be a TWiT show but has branched out on it's own. (https://feeds.feedburner.com/twis/science/)
Buddhism
I listen to a lot of random budhism podcasts but this is the must listen to.
Vedic Mythology and Mantras Podcast: While not Buddhist specifically I have always loved Vedic mythology and Indian music. In my mind the relationship between the Vedic traditions and Buddhist are similar to Judaism to Christianity. This podcast gies a short mythological story and a chant that goes along with it. It's no longer being produced but it has lots of episodes to listen to. (https://www.puja.net/wordpress/category/mythologypodcast/)
