When possible, I do a video netcast on these topics: Dr. Bill.TV - an overview of tech news with a bit of humor! The Chromest Netcast - about the Chrome OS and Chromebooks. VirtZine, the on-line magazine of virtualization and Cloud Computing, The Hand Held Hack which covers portable devices, and the Word of Faith Netcast, which is a Christian teaching ministry program.
There are audio versions of the video programs as well. As well as the audio only Traditional Naturopath podcast, which covers topics in Natural Health and Health Freedom issues.
