Yikes! That's over 50 mil per year, for IT costs???? And this company only has 52 employees? This has to be wrong. Even Windows IT support isn't that high.:)
I downloaded this sample virus and tried to open it, but Panther told me I didn't have permission to open it. So, unless you're logged as admin it looks like it ain't gonna work.
30 seconds huh? Do the math.... a typical NiCd A battery has around 1.6 amp-hrs capacity. These cells have a little more, but we'll call it the same. To charge this battery requires 1.6 amps for 1 hour (a little more for inefficiencies), or 3.2A for 30 mins, 6.4A for 15 min, etc etc etc, or ONE HUNDRED NINETY TWO AMPS FOR 30 SECONDS. Now, tell me why I'm not believing this.
CNN Errors and the quarter mile

X-43A Hits Mach 7

· Score: 3, Insightful
Looks like the guy who did this reporting for CNN isn't much of a techie. A few things he got wrong: (1) "scramjet, which uses air for fuel" -- quite a few people will read that as not requiring ANY onboard fuel at all. (2) "shortening the trip between New York and London to less than five hours" -- we can already do that in LESS than 5 hrs. (3) "it flew under its own power for six minutes to do maneuvers over the ocean" -- if you count gravity as its own power. It was only powered for 10 seconds under the scamjet, and "glided" the rest of the way to splashdown.
Now this intrigues me: It was taken to mach 5 by the Pegasus, then it accelerated under the scramjet to mach 7, BUT the engine was only lit for 10 seconds. Does that mean this succer gained nearly 1400mph in 10 seconds???? Wonder what it would do in the quarter? How many Gs is that?
"A driver is responsible for the upkeep of his vehicle if his negligence causes an accident" --- and the auto-maker is responsible for damages if THEIR negligence caused the accident. "a property owner is responsible for its upkeep if someone is injured on his property" --- and the contractor is responsible for damages if THEIR negligence caused the accident. "a computer owner (is) liable for its upkeep if it is used in an attack" --- and the software vender that made it all possible due to THEIR negligence would be partially if not mostly to blame. Simple solution to all this, just Ban Windows From The Net.:)
Science will never find signs of life while listening to the radio. Advanced cultures quickly find betters ways to communicate long distances. For your information, what they use are very high frequency gravity waves.
As an EE I had the "opportunity" to design an active noise cancellation system for headphones to be used in aircraft. I had the perfect test bed - my own plane, an Emigh Trojan. Loudest cockpit noise in the world. Anyway, the technique seemed simple enough - place a mic outside the earpiece and apply the outside noise to the earphone speaker, phase adjusted by whatever was required to cancel the outside noise striking the eardrum (a single point). The problem was that every frequency (or small range of frequencies) needed its own amount of phase shift, which complicated matters tremendously. The phase shift needed, due to the wavelength "distance" between the mic and the eardrum, was not right on 180 degrees like one might think. The final "product" helped quite a bit but was still not something I would want to try and market (which it wasn't). If you notice in the article, NASA also gave up on designing a noise cancellation system at airports.
The problem NASA faced was much more difficult than mine. The source of the noise and the eardrums of the receivers were never in one fixed location. So, not only did they have to apply a phase shift to several bands of frequencies to the noise cancellation sound generators, they also had to apply different shifts, and different amplitudes, depending on the location of the noise source and the eardrums. Yes, I can see why they passed on that one.
The Professor's problem lies somewhere between the one I tackled and what NASA tried. His advantage lies in the fact that he can place his noise cancellation speakers relatively close to the noise source. That helps a lot, in that the wavefronts from the two sources can radiate outwards from a single point (almost) and be cancelled no matter where the receiver is located. I suspect one of the reasons he can only attain cancellation at the high end (the whine) is due to the poor low frequency efficiency of the speakers.
1. "How many us have spent HOURS a day installing and installing and rebooting and rebooting."
Not me. And when an upgrade does come along I let it install in the background while I continue to work, and if a reboot is needed I'll do that when I get around to it.
2. "Nearly every major piece of software on any OS, especially those that accept network connections have had multiple vulnerabilities over time. Even those developers who are extremely diligent (ie. OpenBSD) have had their share of problems."
Yes this is certainly true. But some OS's have far fewer than others. And it's those "others" that rightfully should get raked over the coals.
3. "Ok, ok, patching is a part of life -- that's understood."
And it's exactly this sentiment that really amazes me. Why in h*ll would anyone put up with the security flaws and patch-n-fix routine that MS has allowed to become so commonplace. There really *is* a better solution.

Relieve stress? Switch to a Mac IT department.

The law we *really* need is a law that says for every new law passed, two should be removed from the books.

While we're on near-trivia: it is not well known outside the binaries newsgroups, but Ada Lovelace was the great grandfather of Linda. :)

Ummm.... isn't this like MacOS running VirtualPC? I mean, really, what's the big difference?
