Solving a Wiring Mess?

All very good points!
However, I've seen a lot of work by *licensed* electricians that was terrible, too. Recently, as a matter of fact.
Point? Get an outside inspector to check the work after it's done. I'm not a licensed electrician, but I do know enough to do most home wiring (and some business too). When done I *always* have someone else inspect it. It's the old adage - you are most blind to your own mistakes. It holds true for professionals as well.
"(In New Jersey, you can negotiate with the building inspectors about not noticing things, but Darwin usually wants bigger bribes than they do...)"
Heh. So true. I have a 110v burn scar on my left hand from twenty years ago that constantly reminds me....to make sure that the power is off and not rely on the person that wired it to have wired it correctly (reversed hot/neutral). The person that did it in that case (my folks' home when I was living there) was a licensed electrician...for a little while longer.:)
"building code electrical code that says who's allowed to work on what kind of electricity."
Umm...most US states nowadays follow the UBC - and who is and who is not allowed is a seperate state law. It can get quite complicated.
Well put tho. Most of my coworkers think I'm way too paranoid about checking for hot wires. That's *their* problem:)
The main application for this is, as far as I understand it, is high altitude to orbit engines. So any noise is too far up to make any difference anyway....
I remember studying this in college back in the 80s. It was still mostly theoretical then. despite the amount of research that had gone into it. The main problem back then seemed to be fine control of fuel delivery, ignition and monitoring of the results. Computer control seems to have solved at least part of that. It looks like, from the article, that precision machining and hightemp materials might have solved some of he other ones problems.
Hell, maybe I'll make it to space after all.;)
If they can really make this work, real-world, it might revolutionize high-altititude to orbit engines. It's probably at least a decade away from production use, but still....
Then why are power companies (in some areas, I'll grant) so willing to pay for upstream power generation?
If they dont' need it, they wouldn't pay for it.
Although I do agree about nuclear power. We need more plants. Things have been on hold for too long. However, that doesn't address local needs - the grid can still get overloaded locally because the local transfer stations aren't up to the demand. Local power generation - like putting solar cell stations everywhere we can - could address a lot of peak load problems, couldn't it?
Update: After talking to a local EE with the power co, that was a local overload problemm not related (as far as he knew) to the midwest grid problem.
We are on the midwest grid tho, from the CNN diagrams. Criminy, it reached as far as western South Dakota? Makes sense, I suppose.... our grid here probably blipped when it helped take on the midwest load that the Niagra collapse dumped.
That's very true....but what do you want to bet it was simply too many air conditioners running and a blown substation somewhere from overload?
Here where I live we get short term blackouts in the mid afternoons every time the temp exceeds 100F (which it has a lot this summer)...we had a short blackout about an hour ago, transformer at a substation about a quarter mile from here, I actually heard it go - kind of a dull boom.
Biologicals, OTOH, if they have a high infectious rate and kill slowly, could be incredibly devastating...potentially much more so than a single nuclear weapon if used in a crowded metro area. Fortunately they haven't been (so far - *shiver*).
Imagine something with the infection rate/ease of the common cold virus(ii) but which kills within 1 week, and is as difficult to counter as, say, HIV.
"Israel Known to have nuclear weapons capability, but has never declared it or tested. It has an estimated arsenal of 100 warheads and a missile range of 940 miles."
They've had 'em for a long time, since the late 70s IIRC.
I saw an interesting article a while back postulating that if weather patterns do become more severe, than a lot of places could see more precipitation (meaning more snow) and therefore global warming could actually jumpstart another ice age...
I don't pretend to understand it completely, but it makes sense to me. I do know that where I live, the weather extremes have become more and more extreme over the last twenty years.
I opened a hotmail account when I bought and installed XP (when it was first released).
I didn't use the account for *anything*. Two weeks later I checked the account and there were over 60 spams in there. I didn't use any dictionary checkable words, or even anything halfway recognizable, in the account username, either.
I realize that was a while ago (two years late this fall) but you can't convince me that MS wasn't passing on hotmail account usernames to spammers. Don't even try. The funny part about it was that a fair portion of those spams were viagra spams....
I agree with you on most points, but calling OE "reliable" is not one of them.
I've lost count of the number of crashes I've gone thru with OE in which I've lost emails that were downloaded...or had folders disappear mysteriously....
I quit using it on the windows box about a year ago. Went to Mozilla's email client, which, while not perfect, at least didn't mysteriously lose messages.

Actually 110v US will grab you and hold on. 220v throws you. It's a tossup as to which hurts more.
Yes, I know from experience.
realityshunt
It probably won't stop, at least not for a while.
The stupendous ignorance of most politicians, judges and lawyers about IT has to be rectified, first. That's not likely to happen.
The idiocy is reaching new heights...
realityshunt
Interesting. Source on the warhead count?
...
I agree about the refuel, but I most of Israel's potential targets are within the 940 mile range already

Don't forget the big spoiler....perhaps canards too? :)

My reaction to this is "So what?"

Utterly cool. Cut off not their research funds!

One good link
realityshunt
and that doesn't even mention the times spent determining if anything else in the transfer stations got blown when everything went down/up
sigh
At least this time there doesn't seem to be much panic.

LOL
:) not that it was much (so hard to click that AC box, I know ) Heh
I saw that coming when I made the post but was too lazy to type out the entire "air conditioners"
deserves a funny mod tho for effort
realityshunt
Especially when the grid is already overloaded from too many AC's going....a few extraneous induced currents here and there...
realityshunt

Chemical weapon effects are mostly local.

Exactly!
From your link:
"Section 106 of the 1976 Copyright Act generally gives the owner of copyright the exclusive right to do and to authorize others to do the following:

No mention anywhere about only one copy being legal...I think they're confusing Fair Use with copyright in general.

Am I the only one who feels that this is the opening move by MS to drop support completely for security updates for OE?
