Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Well, you may be correct on that, however, you have the right to contest a decision by the AHJ to the NEC to a court and they must specify what code violation according the the NEC that has been broken... again it is an interpreting body... just as the Supreme court interprets the Constitution, but they have no authority to change it.

IF not having it grounded bothers you, it cant hurt to ask nicley
Keep in mind that it might be expensive to rewire the entire building, but it woudnt be nearly as expensive to install the ground spike and just rewire an outlet or two that is likley to be needed for electronics. If I owned my house, thats probally what I would do until I can afford to rewire the entire thing
The adapters can be used in a pinch, and PROVIDING the utility box itself is grounded, your equipment will be grounded (providing you're using a metal screw on the adapter!!!!!!!!), but it's not the ideal solution. I've already posted how to determine how to test if the outlet is properly wired; follow the same directions to test whether the utility box itself is wired. Basically, touch one probe of your voltmeter to the (metal) screw holding the trim plate to the fixture, and touch the other probe to the "narrow" side of the outlet. If you read between 110V and 120V then the utility box is grounded, and the adapter will provide an adequate ground as a temporary solution and will provide some protection for your equipment.
Also: since when are those adapters illegal to use? They're illegal to use for PERMANENT solutions, but not temporary. Are you aware that it's also illegal to use extension cords longer than 6' for permanent situations? Also, appliances cannot have power cords longer than 6' because otherwise they would be in violation of that law? It's not in the NEC that I can recall;l it's an OSHA regulation. Check OSHA sometime.
Also: you don't want to run a UPS on a circuit with a GFCI; the GFCI can falsely detect "leakage" from a UPS when the UPS is monitoring/testing the circuit or when it switches on/off the battery power, tripping the circuit.
I came on this site trying to figure out what is wrong with the wiring in the apartment building I just moved into. I've felt electricity tingling my hands when I've picked up my alarm clock to change it or turn off a lamp. Everything is for two prong usage and I was told that the apartment building has been approved by a housing authority called Hud. Now I'm not so sure that's true (my landlords are very kind and I don't want to be suspicious that they weren't truthful about it being Hud approved).
What is your advice on what I should do?
