Two biggest worries as a homeowner: water where it shouldn't be and no water where it should be.

Yes! 80% of home ownership is essentially water management.

No mention of the chimney.

For "people" it would be Santa. The "smoke" row would be fun.

Do you know anyone who actually uses power over Ethernet? Every motherboard I've ever bought supports it, but I don't know anyone who uses it.

Although the inverse, networking through your power line certainly used to be a thing. It looks like people still do it sometimes.

PoE is amazing for certain devices. Cameras (including video doorbells), and WiFi equipment.

I use it on every phone handset at work... I guess it's the switch PoE not the pc mobo but the effect is the same. If you are talking pc mobo PoE I guess it could be handy if you had a PoE camera...

Electricity in garage, bad?

[–] [email protected] 1 points 1 month ago

In the garage is fine, but this is about inputs and outputs. Electricity entering or leaving a house via a garage (or front door), and not via power lines, generally indicates something is very wrong. That's quite a large air gap to cross after all.
