That works for much of the file space, but doesn't help you much for files that have created and deleted during the installation process.
Another way to get a similar result is to install the os, then create a file filled with zeros to derandomize the unused space on each partition. Afterwards, erase the file and image the drive.
What I find laughable is the statement that black powder (especially 17th century black powder) would have the same explosive power as an equivalent mass of TNT. As an example, when used as a bursting charge in an artillary shell, black powder is only 1/3 to 1/2 as efficent as TNT.
I have a Nokia 3650 (great phone, btw) and the bluetooth is great for some things, but painful for others.
Finding a BT headset that would work with my phone was a royal PITA. It seems that Nokia has a funky handsfree profile that most headsets won't play nice with. The headsets pair just fine, but then won't do anything useful.
Jabra has upgraded the BT200 to be compatible, but some that are in stores are the old version and some are the new version.
I do love the ability to automagically sync my palm, my iPod and my 3650 (via bt) all at once from my G4.
There's NO way they're going to be able to track anything with this technology. At least not with existing cell towers and antennas. I've heard of similar systems in an Anti-submarine Warfare environment that used pings emitted by other ships as a way to detect submerged objects, but those systems depended on phased arrays with a large acoustic aperture (think $$$).
Given how dynamic the cellular environment is and the fact that they're only talking about $3000/site * many many sites for hardware, they're not going to be able to get any useable accuracy (nor will they be able to differentiate between objects on the ground or in the air since they don't have an array that can form beams vertically).
If you're concerned about being tracked, there are technologies that are much more capable that don't use GPS, nor do they rely on the phone being used. It just has to be turned on.
The infrastructure-based systems use either the arrival times to each antenna (which requires VERY good time syncronization) or they calculate the angle of arrival to a set of antennas. It is also possible to use a combination of the two techniques and use an angle of arrival combined with a time of arrival and get a cross-fix that way.
In general, the time difference of arrival method is subject to multipath errors, while the Angle of arrival method is more resistant.
I've seen the AOA system work over very large distance and come very close to meeting the FCC-mandated limits of accuracy.
I worked for a company some years back that did a lot of the early development on the angle of arrival method. They were WAY ahead of their time and ended up selling out to competitors. Such is life.
Since the Apple site is going to get knocked flat, here's a copy of the page.
Monday, 5:57 PM: Virginia Tech's G5-based supercomputer is (sort of) running-- with 17.6 teraflops of theoretical performance. Meanwhile, Dell tries to build something (sort of) similar, but it winds up with a quarter of the power and seven times the price, and Apple (sort of) announces Xgrid, a product for "parallel and distributed high performance computing"...
Monday, 5:57 PM: Today's holiday episode is now broadcasting. Don't forget to take your shot for a free AtAT shirt (tee or turtleneck) by entering the Q4/03 Beat The Analysts contest; guess closest to Apple's final reported quarterly profit or loss, and you get the garment-- or your choice of creaky old software from the Baffling Vault of Antiquity(TM). You've only got until Wednesday at 4 PM, and in the likely event of a tie the earliest entry wins, so why wait? Enter now!
Up, Running, & Kicking Tail (10/13/03)
Fun fact: believe it or not, folks, AtAT's wild success isn't confined to these here United States. No, seriously, it's true! The show actually has semi-regular viewers holed up in such far-flung corners of the world as Iceland, the Dominican Republic, and Delaware-- and for the benefit of those fans, we thought we'd explain that, here in the U.S., today we celebrate a holiday called Columbus Day. Columbus Day, for the uninitiated, is one of our most sacred occasions: a day on which we reflect on the many cultural and technical achievements of the city of Columbus, Ohio. We celebrate Greater Columbus's world-famous quilts, its shrubberies recreating Pointillist masterpieces, and (most importantly) its commitment to the preservation of really old TV sets by wondering why the bank is closed and our mail never came. A good time is had by all.
So if this is such a major holiday, why are we broadcasting, you ask? Well, normally we wouldn't, but faithful viewer Nathaniel Madura pointed out that Slashdot just referenced a BBC World report on that G5 supercomputer down at Virginia Tech, and we're just a little giddy about the existence of a Mac-based cluster than can chew through 17.6 trillion floating point operations per second. Yes, the thing is up and running (at least enough to run performance testing), and reportedly it pumps out 17.6 teraflops of raw perforated aluminum muscle while sucking down enough juice to power 3,000 average homes. Wow, is it getting warm in here, or is it just us? (It's just us-- the G5s are cooled by means of 1,500 gallons of chilled water pumped through every minute. Ooooo, frosty.)
Kudos to the Virginia Tech team who pulled this off, because frankly, this is the sort of technological triumph we'd normally only expect to come out of, say, Columbus, Ohio.
Now, what's interesting about that 17.6 teraflop figure is that if you scope out the last compiled list of the world's top 500 supercomputers (from last June), you'll notice that, if 17.6 teraflops is Virginia Tech's "theoretical peak performance" score, it'll probably slot in nicely at number three. (Scores are ranked by "Maximal LINPACK performance achieved," so it's just guesswork so far.) The top-ranked Intel-based cluster is currently ranked at number three, with 2,304 2.4 GHz Xeons and a theoretical peak performance of 11 teraflops. Gee, more processors, a higher clock speed per processor, and 63% of the performance. Now that's efficiency, baby!
We'll have to wait until the next top 500 list comes out in November to see if "Big Mac" (as the VA Techies apparently call it) really takes third place, or if the real-life LINPACK scores push it down lower-- but we figure a top five placement is a safe bet. One of the world's bestest supercomputers made of Macs and running Mac OS X? Why, it's a Columbus Day miracle!
4x The Bang, 1/7 The Buck (10/13/03)
Meanwhile, we know that the G5 supercomputer is delivering more pluck per processor than any other supercomputer out there, but what about bang for the b
Yeah, maybe. I have the 3650 as well. The phone rocks, but the dialpad is a bit weird.
So far I'm not too impressed with the Bluetooth headsets out there either. I bought one from Belkin and one from Jabra. Neither one would work with the 3650's Bluetooth profile. I suspect that the 7600 will have similar issues
The 7600 looks too bizzare and the keypad looks like it will be nearly useless.
I agree with you to an extent. If you try to mask bad playing with effects, you're just a poser (or maybe a metal band (ducks for cover).
With any instrument, one should be able to play without any effects as a way to improve their technique. It's nearly impossible to hide the fact you just missed half the frets you meant to hit.
That being said, acid rock is damn boring without that fuzzface in front of a nicely distorting tube amp.
Controlling effects and using them musically is an extension to ones basic control over their instrument.
I do a large portion of my practice on my acoustic or with my Strat playing clean. When I'm done with that part, I work on using the distortion to get the sound I want from my effects and amp.
I've known two Phd IT types and while they're very knowledgable in their field, they spent more energy trying to be "elegant" or inventing new ways to do things (IOW something cool that they thought of but wasn't standard) rather than doing things the right way. I think they forget that production IT shops aren't staffed by students.
In the proper job (a very high-level IT role or in education), a Phd is a valuable asset. In a production shop, it's slow death. Everyone gets sidetracked chasing dreams.
For GPS-enabled phones, you can probably turn the GPS part off.
For infrastructure-based systems, if the phone is on, it can be tracked. How the phone company chooses to safeguard the information is the real issue. It's possible to decouple the identity from the data for purposes doing things like traffic probes.
The infrastructure-based systems use either the arrival times to each antenna (which requires VERY good time syncronization) or they calculate the angle of arrival to a set of antennas. It is also possible to use a combination of the two techniques and use an angle of arrival combined with a time of arrival and get a cross-fix that way.

I think that old Darl (www.tubdarl.com) bit off more than he can chew! IBM
has more seasoned lawyers that specialize in patent cases than SCO has
employees.
Anyone notice that SCO's stock slipped another 11% today? heh.
While I believe that micropayments or subscriptions are likely to be
more commonplace in the future, it will be difficult to sell to the end user.
We've been accustomed to free content and will tend to avoid payment whenever
possible. Most people (especially AOL users) will figure they've already
paid and shouldn't have to do so again.
Salon Magazine has been forced to modify its subscription model in order
to survive (if you call that surviving).
Perhaps one model that might work is a monthly credit from your ISP that
will go to pay for initial usage of pay/view content.
Given how few people will even pay for Slashdot content, we're not likely
to see this widely adopted anytime soon.
Wire up the ADHD kids with piezo transucers and you'll solve the energy crisis pretty quickly. Just make sure you toss 'em a few candy bars now and then.
My kids have had cameras in their preschool classrooms for some time now, and the other parents are REALLY paranoid about others (non-parents) observing what goes on.
Yeah, I was thinking the same thing, but you'd also need to eye to focus on the wall long enough to accurately capture the image. If they don't focus, you'd probably get a blurry shot. Plus, you'd need to illuminate the retina enough to get an image.
Of course, we could be completely evil and offer a free peep show: "Step right up and look in the hole boys, see the thrill of a lifetime" click.
Although I agree with much of your post, retinal scanning from a distance is pretty far-fetched. Think about how a lens works for a second. In order to see a significant portion of the retina, you'd have to be very close.
Iris scanning is possible from a bit farther away click here for info and facial scanning from even further away.
and let's not forget the effect of multi-path in the equation. In some cases, multipath will improve the SNR, in others, it will reduce SNR. Simply using signal strenth is inadaquate. Using a set of directional antennas will work better, but then you have to have helpers or some very expensive phase detection equipment that will work for azimuth and elevation.
The more stuff you can do in hardware (encoding,decoding,yadda), the less stuff you need to do in software. You can then have quieter fans, less heat, less RAM, etc.
I'd say that more bucks flow in the the coffers of god.com that any other company out there. They have certainly wielded more power over recorded history than even Microsoft.
That being said, waste seems like the next logical step in P2P applications. I was astonished how well bittorrent worked the other day when the clusteredKnoppix site got hammered after the article on Slashdot went up (speeds up to 2.9 Meg/Second).
I'll bet AOL is really sorry they bought Nullsoft.:)
Slashdot Mirror
NOT!!!
Geez... Even if his plan works, how does he propose to tax email originating outside US borders?
What's next? A Internet Stamp issued by uspo.gov? I'll bet the post office just loves that idea!
Schmuck.
Given that the ftp servers are getting pretty whacked, a link to a .torrent would be very welcome.

The problem with the civil war variety is that they submerged more times than they surfaced.
Seems they got too much water in the people tank. That tends to be bad for morale
Geez.. That sounds like someone else we know....
Hmmm... now who can it be?
Perhaps.....
SATA^H^H^HMicrosoft!!?!?!?
Oh yeah!!! That's the model that uses a cold fusion power source and will let you sell back power when you're docked.
I have mine on order right now!!!
I'll be selling my old model T, T2, and T3 on ebay real soon!!!
