I found this on the Fediverse last year, so am sharing again as it was originally shared on the Devon & Cornwall Linux user group website.
As the name suggests this allows you to search for a pod cast in a good range of topics.
Libre Lounge is another podcast that has covered different aspects of the Fediverse, this includes some of the more technical aspects including a multipart discussion on Activity Pub. Activity pub is one of the protocols that allows posts to be federated across the network.
