  1. Re:What year is it? on New Dell Laptops Give Users a Literal Shock · · Score: 1

    Actually, if you live in one of those houses then you probably know about the three prong to two prong plus ground clamp converter. They are meant to be used with the clamp actually grounded but you COULD get by without using it like that. Of course if you live in a house like this your lucky to get a computer to work at all as your power is probably 20 shades of dirty.

    Those adapters are dangerous. Most people ignore the warnings printed on them and don't connect the ground tab, and of those that do they often times don't know or understand the difference between a grounded and non grounded receptacle and don't understand that just because there is a screw in the middle of the two pronged receptacle to connect the ground tab to it doesn't mean that the screw or receptacle is properly grounded, in fact most of the time it isn't in those old houses as there is no proper ground source at the receptacle at all. The only way to properly ground one of those receptacles is to get a qualified electrician to ground it properly who will find a nearby ground source (such as a cold water pipe) and run a ground wire from it to the receptacle and replace the receptacle with a proper three prong receptacle.

    If you don't know what you're doing you could end up thinking that you're safe when you really aren't. That's worse than knowing you aren't safe.

  2. Re:The 3rd pin isnt much different from the neutra on New Dell Laptops Give Users a Literal Shock · · Score: 1

    True, but there are a few differences:

    1) The ground wire goes to the metal casing of the outlet, not all the way to the grounding bar, to eliminate the possibility of 'floating' voltages or charge buildup along the neutral.

    Actually, the ground wire goes to both. It is normally grounded to any ground screws or wires on attached receptacles, switches, light fixtures, etc, plus it is grounded to the casing on any metal boxes it passes through (but not on the plastic boxes that are more and more common these days as it's rather pointless to ground plastic). The ground wire does terminate on the ground or ground/neutral bar in the service panel.

    2) The ground wire typically connects directly to the metal case of the device, so that if the hot wire accidentally makes contact with the case inside the device it won't shock the user.

    This is correct, plus it will also trip the circuit breaker.

    3) Although in principle you could get these benefits from hooking up the neutral to the case and doing away with the ground wire, it would have dire consequences if the user reversed the plug. Therefore the ground plug is triangular and not reversible.

    If the plug is polarized then you could not reverse it without filing down the wide (neutral) prong. That said, there are other reasons to properly ground a metal casing as others have pointed out the neutral can carry a small current and is not suitable as a proper ground, plus faults in the neutral will leave you with a 120 V AC hot casing. Note also that the ground prong on a typical ground plug is longer than the other two prongs. This is on purpose to ensure that the ground is always connected first when plugging an appliance in and disconnected last when unplugging.

    But its true that the ground wire is a holdout from those days when we used to have metal cases on everything (remember those metal drills - and the XPS, apparently). If the hot wire touched the case the user would get a shock, hence the ground prong.

    I would hardly call it a "holdout". There are lots of devices that still require a proper ground and have metal casings a brief list off the top of my head is:

    • Major Appliances such as refrigerator, dishwasher, electric ranges and ovens, washing machines, dryers, waste disposal.
    • Desktop computers
    • Workshop tools such as drill presses, Skill saws, etc.
    • Almost all industrial workshop equipment.
    Certainly we will not have an end to the requirement for grounding any time in the foreseeable future.

    The ground (green) wire has to be connected to the neutral bus or it would be point less (no return path).

    Not necessarily true. The ground wire (third prong, etc), simply has to be grounded. There are lots of cases of old houses where a power point has to be adapted from non-grounded (two prong) to grounded (three prong) and there is no ground wire in the outlet to do it with. The most common way is to run a ground wire from the outlet to the nearest cold water pipe (plumbing codes in the US actually require that enough iron or copper be buried so that the pipe can serve as an electrical ground).

    * The neutral wire has the same amount of energy running through it as the black wire!

    This is only true for a single phase circuit, in dual or triple phase circuits or two or three circuits that share a neutral (because they're on different phases) the current through the neutral wire depends on how much current is being taken up by the different hot branches. It is entirely possible that you have current flowing in one hot wire and out another hot wire and the neutral doesn't pull any current at all. Of course that said, you should always assume (for safety purposes) that the neutral is pulling as much current as the hot because it can.

    There are global wind currents that allow you to sail in either direction depending on what latitude you're sailing at. So if you're crossing the Atlantic, for example, you simply sail one way at a certain latitude to catch the wind current favorable to you and come back at a different latitude, thus you get favorable winds in *both* directions.

    Also, these same wind currents are what drives the ocean currents that even modern day vessels take advantage of to save on fuel and decrease travel time, so it stands to reason that current shipping routes will already be ideal to take advantage of favorable wind and ocean currents.

Unfortunately the current president has claimed "executive powers" and is attempting to run the country contrary to the will of congress and the will of the people, but that's not the way it's designed to work.

    The US government is very similar to the structure of a corporation. The president is the CEO, congress is the board of directors and the people are the shareholders (each citizen holds an equal share in the corporation and is entitled to one vote at the elections or "shareholder meetings"). As such, the president is answerable to both congress and the people, and congress is answerable to the people.

    It is very important for Americans to be able to vote for all the different things that we have the power to vote for, and I would never want to see that power taken away from the citizen because the ballot is deemed "too complicated". There is nothing preventing someone from just voting for president and leaving the rest of the ballot blank if that is what they want.

    What's the point of electing people if you can't delegate to them some of the decision making. Here you're confusing state and local government with Federal government. In the Federal government congress has full power to make all laws, so the people don't do that directly. The people do vote in representatives of congress to make laws for them, so your statement doesn't even apply to Federal government. State governments vary and while most allow the people to propose referendums (commonly known as "propositions") and vote for them at election time there are some that follow the same model as the federal government.

    It all does seem very complicated but in the end you have a government that is more responsive to the will of the people, especially at the state level and that is a good thing imo. I would like to see the federal government adopt the ability for the people to vote on referendums as well, I think it would make things way better, then.

    Here's the problems you will face. If you license under GPL version 2 or later then you can't incorporate code that is licensed under version 3 (but not version 2) into your project (others here seem to imply that you can) until you move up to version 3 yourself. Basically you need to think of it this way, in order to use other people's code in your project your license has to be a subset of their license. In order for others to use your code their license has to be a subset of yours. Here is what I would recommend:

    • License your project as a whole (and all included files) under GPL version 2 or later for now.
    • Continue to License under GPL 2 or later until you need to incorporate code that is licensed under GPL version 3.
    • When you need to include code licensed under GPL 3 or later (try to avoid any code licensed under GPL 3 only) then you can relicense your project as a whole under GPL version 3 or later, but keep most of the individual files licensed under GPL 2 or later. Only those files that include the code that was licensed under GPL 3 or later need to have their license headers changed.
    • If you need to include code licensed under GPL 2 only, then contact the authors and ask for permission to relicense that specific code under GPL 2 or later, most (but not all) will happily give you permission to do that. Barring that you will have to find another source of the code or write it yourself.
    • You can, of course link to libraries licensed under the LGPL, and include code licensed under BSD (as long as you comply with the attribution clause). As of GPL 3 you can also include code licensed under the Apache license, plus there are several licenses (such as the perl license) that are actually dual licenses of GPL plus some other license and code from those can be used freely under the GPL (watch out for what versions they specify). Have a look at the Free Software Foundation License Compatibility Page for more details on lots of licenses and their compatibility to the GPL.
    • Watch out for version numbers. If a program specifies that it is licensed under the GPL (without any version number) then it can be used under any version of the GPL. If a program specifies that it is licensed under GPL Version 2 (or some other specific version number) then you can only use the code under that specific version of the GPL. Most programs will specify version 2 or later (and many will soon change to version 3 or later) which means that you can use the code under that version or (at your option) any later version.

    As for allowing others to use your code, you have some options with that as well:

    • You can dual license, or multi-license specific files in your project so that they are compatible with other licenses you want them to be usable with, just don't forget to remove the other licenses from any files that you include someone else's GPL code in.
    • You can give explicit permission to others to license under other licenses of your choice when they write you and ask, just make sure that you specify which parts of the code they can only use under the GPL (and which versions) due to it not being your code.

    I think this about as comprehensive of a guide as I can give you. I'm not a lawyer or a representative of the Free Software Foundation and my statements above are just opinion and not to be taken as legal advice. I just know what I know and am passing that knowledge on.
