    In household wiring polarity does matter, especially if you are assembling plugs. Only one of the three wires is carrying live current (hot), the other two are the neutral return path, and ground which is for safety. If you accidentally switch polarity, you can cross hot to neutral and cause a short circuit.


  • Psychos aren’t the ‘scream in your face and belittle you’ type of people, it’s the silver-tongued devils that talk about family values and the environment and how their thing helps people, all while making backroom deals and lobbying governments to pass laws in their favour or any other number of shit. Psychos will appear on the surface as the nicest goddamn person you ever met, and you won’t think otherwise until you find the knife in your back.




  • Pretty much the first thing that needed to be solved when moving from 1-way pagers to 2-way phones. Pagers could just get a broadcast analog signal and determine themselves if they were the intended recipient. 2-way needed more bandwidth and a dedicated communication channel to a specific device, so broadcast wasn’t feasible. Thus, phones would send a registration signal that a tower would pick up, and that specific tower would handle all communication to that phone. If another tower got the registration signal, communication would switch to that tower.

    Interestingly enough, there was a period (for a fairly long time) that if you were travelling too fast, you could either a) not be able to register on a network, or b) overwhelm the network with registrations - part of the reason why phones had to be turned off on airplanes
