Recently, a bit of Twitter drama has arisen from a post that started with @JWWeatherman_'s disclosure of a perceived critical bug in the Casa Node device. Today, to start off a discussion of home network security, what self-signed certificates do/don't guarantee, and the general trade-offs between security and usability, we read CasaHODL's blog post responding to JW's concerns, and then we get Guy's take on this as a Casa Node user.
