Excellent work. Well explained
Great host, great topics, great technical deep dives sessions and Steve is great at separating the real story from the headline news!
There is so much good security information and also interesting technical knowledge teaching on this show. Additionally I love the occasional SciFi recommendations.
I already reviewed SN audio and it beggars belief that Apple cannot link the two versions. Anyway, I enjoy watching SN in video format (my wife less so) and the two old crooners do a great job in keeping me updated. I‘ve been listening for longer than some people have been alive, certainly from before Leo got his longest crowdsurfing award at some DiggNation event…!! Live long and prosper!
