  • It’s a combination of conservative designs, robust training, and a zero tolerance safety stance where even minor misses that have any relationship to the reactor or power systems get throughly investigated through a formal process that seeks to understand and learn from mistakes rather than assign blame.

    If anyone is curious, the Naval Nuclear Propulsion Program (NNPP) publishes the Gray Book with some history of the Program, the various arms that are involved to make it successful, and how the Program is managed including training, suppliers, labs, and fleet operations and maintenance.

    Turn the Ship Around is a leadership book that also touches on safety and operations of a nuclear sub and is just a good read overall if your looking for a different way to think about bringing a leader in an organization.


  • There are two things in my house I don’t “play” with: internet connectivity and core home functions (lights, locks, garage doors, etc). That doesn’t mean I don’t self host anything or then, but I always start from a mindset of “must work”.

    I run HA on a Yellow (functionally an RPi 5 with radios and storage interface built in). My lights are either Hue running as plain Zigbee devices, or Zigbee switches. I don’t necessarily want more customization with home automation, I want stable, extensible, and easy to use day today. HA checks all those boxes easily. I’ve not done much looking into OpenHAB, but I would caution against going with something for home automation just because it’s more customizable. Sure, it’s great to have an automation routine that turns on your lights when you get home, it’s less great to have an integration that misbehaves and now you cannot turn off a light, or lock your door, or turn down the volume on your music, etc. Be sure to know what you want to accomplish before you buy devices, build automations, and always build things with a manual backup operation option.
