Of course at the time I was crawling through that particular press the latest thing in digital was an IBM 360 reading punch cards and Amaco "white" gas was about the only lead-free in exisitance.:-)
A "digital" Heidleburg? My mind boggles, but that's cause the last time I was around a Heidleburg it was the size of a 58 Buick and had to be scrubbed down once a year (in the middle of summer of course) with Amaco "white" gasoline, and I was the low man on the totem pole who had to do it.
How is calling someone "one of our most knowledgeable people" abusing them?
Of course the original story, or, I should say, some of the versions of the original story (how often can you rewrite the original and it still be the original?) mentioned "...when our qualified personel arrived, we discovered that she wasn't actuually as qualified as we had hoped. Then she quit..." which doesn't sound like someone who was already not working there anymore before the troubles started, so I assume that we're talking about 2 different people here, only one of which was identified one way or the other by sex/gender.
Quite a ways down in the responses to the aforementioned "original" story is an AC post signed Anne Tomlinson that seems to give another perspective on the events that weekend. It's a little ways down the page from another post that has some of the different versions of the original story.
All wires have inductance. If current flows through them there is an associated magnetic field. Any change in the level of current causes a change in the magnetic field. Any change in that magnetic field induces a current in any nearby conductor (or at least a voltage difference between the ends of that conductor that will cause a current if it can find a complete path), including the original conductor through which passes the current which generated the magnetic field in the first place. In that original conductor the induced voltage, or electro-motive force (EMF) is in reverse polarity to the original voltage, or EMF. Any change in the original EMF level causes an EMF that fights the change in the original. It's kind of like a 3 battery flashlight with one battery turned the wrong way, you subtract its voltage from the total voltage of the other 2.
The faster the change in the level of current, the greater the opposition of the induced EMF in the original conductor. This opposition, called inductive reactance, increases as frequency increases.
Any time a wire is looped back on itself, whether as a turn in a transformer coil, or a knot in a power cord (remember, the "hot" and "neutral" lines are connected to each other through the load and through the source, and the same current that flows down one flows back up the other, they're part of the same series circuit), or as a twist in unshielded twisted pair (again, both conductors are part of the same circuit), the inductance is greatly increased over what it would be without any "looping", because the proximity of different parts of the same conductor to each other intensifies and reinforces the magnetic field.
The power surge that tends to burn out equipment isn't the original lighting bolt, it's EMF induced in the electrical lines by the lightning. This induced "spike" tends to have an almost instantaneous rise-time. Therefore it can be considered a very high frequency current. An inductance (coil, loop, twist, knot, etc.) with negligible reactance at 60 Hz is going to have a very high reactance, or opposition, to that spike's much higher frequency. Most of the spike's energy is going to be used up in trying to shove current through that high reactance knot. The voltage drop across it, the difference in potential, is going to be most of the total voltage of the spike. Most of the total energy in the spike is applied to the knot. This high voltage will probably cause enough current flow in the knot to burn up the insulation and possibly partially melt the wire itself. If that spike didn't drop off as fast as it rose then eventually it would force a destructive current through every path it could find, knot or no knot, but fortunately individual lightning strikes end as quickly as they start.
My original post was a joking reference to "the mark of the beast" or whatever that phrase is from the Book of Revelations (may not be exactly correct title). Yours, however, is just a little too close to real possibility for laughs.
Go back and study some more. Study until any mention of wires in the same circuit crossing or twisting around each other automatically makes you think "inductance".
See alyandon's explanation immediately above for an excellent explanation of why overhand knots in the power cord work. I commend it to the attention of moderators as well. It is an excellent example of the type of comment that positive mod points are designed for.
See Mark Minasi's "The Complete PC Upgrade & Maintenance Guide" (9th edition = ISBN 0-7821-2357-0, published by Sybex) for one example of a book containing that technique.
When you say bi-directional Zeners I assume you mean connected cathode to cathode or anode to anode?
Bear in mind that any such thing that you build yourself won't be UL listed and if you start a fire with it your homeowners insurance might not pay out because of that.
Intel, or anyone else, couldn't have bought the Alpha if Compaq hadn't put it up for sale, but that's not really related to the topic at hand.
A few years ago there was talk that Carolina Power and Light was going to get into the high-speed access business because they had all this installed fiber that was only there to transmit meter readings and a little control info, which meant that they only needed about a phone line's worth of the bandwidth they had at their disposal and that the rest was going to waste.
Whatever spin-off company they formed to take advantage of this seems to have faded quickly into the sunset, leaving us at the mercy of dialup or TW-AOL.
I had no idea that there was a Japanese version of Slashdot but one look at it goes a long way toward explaning why so much of the spam I get is composed of (to me) undecipherable characters. How many "foreign" Slashdots are there?
Shouldn't an update be appended to the complete original text of the story and clearly marked as such, rather than appear to be an attempt to cover up something you came to regret having said?
That's the way it is now, but it used to be that telephone and cable TV wires on both sides of the subscriber interface (demarcation point, goes by a lot of different names) were installed by, and belonged to, the service provider, and the customer/home owner wasn't supposed to touch them, and a lot of places are still using those wires because nothing's come up to cause them to need to replace them.
Why can't some clever judge or lawyer find a way to stretch 47 USC sec. 227 to cover spammers sending unwanted "facsimiles" of the original of their email that they typed up to every address they can get their hands on? Facsimile meant a close approximation or copy of something long before there were wires to transmit them over, and the original intent of the writers of that law was to prevent cost shifting.

It appears that that was the problem, that they knew as much about configuring routers as they did about spelling. :-)

Okay, so were there any posts at -2 or lower?
"Hey boss, I can't get ahold of any experts for a quote."
"Well then just find somebody who's awake."
For all we know they are and we can't browse low enough to see it.

Were they ever? I thought the problem was that getting stuff to work with MS stuff was so difficult that it required a lot of technical expertise.
So all this time Microsoft has been giving us the finger? That would explain a lot.
That'll be the one they tattoo on our foreheads, right?
Perhaps what happened over the weekend was that the Slashdot server, having achieved sentience, attempted suicide because it was just so embarrased.

Is there such a thing as an amateurnoun or amateurverb ? Or an antinoun or antiverb ?
Because cable service is only available from one provider in your location? I.e., no one is competing with them for your cable dollar?

Okay, some of them spell it "styli".
