This week we'll talk about some sad news from the makers of my beloved Clarify, then I'll do a crazy deep dive into the National Institute of Standards and Technology about two-factor authentication. I do this to help you understand what your bank needs to know about using SMS or email or a phone call for authentication (spoiler, they shouldn't). Then I'll tell you about how much fun Sandy Foster and I had figuring out how to rip a (non-copy-protected) DVD in a modern version of macOS. In the last segment we'll have fun with geometry as I try to figure out which screen is physically bigger, iPhone X or iPhone 8 Plus.
