Peer Tube
Peer tube is another service on the Fediverse. That allows you to upload video and share this with other. The difference is there are no adverts and fewer limitations on what you can upload. You still need to stay within the law though. Having used this I found it pretty straight forward and it transcoded my video in a few hours. As stated above this is all based on Free / Libre software.
PodCast Search
While on the Fediverse you come across lots of useful links to other resources. One that I found recently was https://podsearch.com/
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.
You can find the Devon and Cornwall GNU / Linux user group on the fediverse at https://social.isurf.ca/profile/dcglug
