  • Sadly my parents’ new IP phone service uses the dialtone as some kind of branding trick - you go off-hook and get this “designed” audio prompt that slides into a normal dialtone, presumably to make you remember you’re not just using “the phone”. It was very disconcerting when I first heard it.






  • I got permanently banned for reporting spam (“abusing the report button”) after I reported 8 Vice articles posted in /r/politics by the Vice self-promotion account in one day.

    Meanwhile, the spam guidelines page says - if you create an account primarily to promote your own content, you may be a spammer. And as a redditor, you should report spam.

    They lost a 12 year long user who primarily engaged in niche technical subjects who went out of their way to answer newcomers’ questions.



  • Yes, the center (neutral) is connected to ground somewhere, but is not a suitable ground reference - because current on the neutral creates a voltage drop along the neutral conductor. A North American outlet box has Hot (L1), maybe another Hot (L2), Neutral, and also an earth/ground conductor.

    Neutral is not ever treated as ground; it’s impermissible to connect it to any bare metallic surface. Other than not being switched, and being the side that ends up on the threads of a light socket, it’s handled the same way as a hot/line conductor. Just like a 240V system.

    It would dissipate static fine, if you were allowed to touch it.


  • I think that’s incorrect. The ground pin is a dedicated equipotential reference bonded to the earth via an acyclic wiring path which carries no current. It does go pretty directly to the ground rod via the breaker panel ground bus. Neutral happens to be connected to it at the entrance panel for fault clearing, but not really for any other reason.

    Since all metallic chassis, pipes, ducts, etc are connected to it and it is available pretty much throughout a building, it is a logical place to connect ESD-prevention gear, even if the earth has little to do with that. (But, a grounding electrode system installed to code should have less than 25 ohm impedance to ideal earth - not exactly a “poor” conductor)
