You need the heel spikes too. A common fall is to have your feet slip forwards. -- -- kensmith(a)rahul.net forging knowledge

What about a Windows Vista >machine? Vista is really a shell. It contains a bunch of XP code. Whenever OS like stuff needs to be done, Vista passes the command to the XP code. Which then passes it down to some Win98 code that fires up DOS and runs the operation through QBasic. This is why Vista needs so much RAM. > > -- -- kensmith(a)rahul.net forging knowledge

I was told that a man whose job related education consisted of an solely of an apprenticeship at Rolls Royce (automobiles) was "an engineer" I almost fell out of my chair. His "maths" consisted of what we call "shop math" over and above the regular schooling all children get. >>>Also, as for Blair's idea that we can do 'R&D' instead of manufacturing, he's >>>barking mad.

Now explain how a country with little > manufacturing industry can support a large R&D industry. Immediately switch from being a socialist economy to a capitalism. R&D is an investment just like any other. How can you *not* afford that?

Before that, it was a DOS LIKE kernel, which had the GUI added onto it. 95 WAS DOS with the GUI added, as was all versions before it.

I shouldn't ave to, with your extensive technical knowledge. LOL > What do you think fuses are there for ? Hint. It's not to 'protect' the > appliance. They're there to "protect" the wiring. In your case there's serious energy at the receptacle, plenty enough to very quickly start a fire. Your receptacles themselves are not capable of safely carrying the current available to them. That's God awful design. If the plastic material of the receptacle carbonizes and begins to arc there's an awful lot of energy available to star a fire. We have, at most, 20 amperes at 120 volts in general use receptacles, fed by wire that will carry that current forever without overheating. And we derate that wire to 80% normal (here's a new word for you) ampacity in those cases where the circuit will be used continuously for 3 hours or longer. UK uses a smaller wire for the ring circuit, counting on it being fed from two direction to each load. The wire, by US standards, is significantly undersized. Presuming a break anywhere in that loop means that the full 30 amperes is available to a terribly undersized wire which can then over heat to glowing inside the walls and ceilings without the protective overcurrent device disconnecting the load. |
