Steve is an engineer's engineer. He provides subject matter expertise on a variety of topics relating to security, internet privacy, and computer hardware. For the things he doesn't know as well, he researches thoroughly and does not speculate at times when many others would find it easy to do so. I have learned a lot of useful things from Steve's podcast over the years and I strongly suggest that you give SecurityNow a listen.

kubernetes podcast from google. A weekly podcast focused on what's happening in the Kubernetes. The hosts takes a topic in kubernetes community and try to explain it in more detail.
It’s one of the few podcasts that focuses on the social aspects of free software rather than just the software itself, and as someone who thoroughly enjoys conferences like LibrePlanet and FOSDEM I feel like it has the same sort of vibe.
And lightning!
