After reading the comments I've come to the conclusion that even out of the slashdot readers who read the article most don't know as much about IDE drives as they think that they do. Looks like Tom and the NickLock folks don't either.
This thing might work if you just happen to have the right hard drives, but if you *don't*, you'll probably wind up ripping it out of the case with your bare hands, flinging it to the floor, and stomping it to powder.
"Paying cash is very likely to flag you as a potential terrorist requiring extra security screening, though."
Or as a drug dealer, and since you'll probably be carrying all your available money on you in cash (being afraid of not being able to get it out of a bank), that will be considered as further "evidence" that you're traveling for the purpose of dealing drugs and that the money is intended to be used for drugs, so even if they can't actually haul you in front of a judge and jury on charge of "looking like he was fixin' to go deal drugs", they can arrest your money, and you have to prove that your money is innocent. Before you can go to court to do that, you have to put up a cash bond of an equal or greater amount, but that doesn't actually bail your money out, so now you've got twice as much money being held hostage.
Shouldn't 1700 have *not* been a leap year? Leap years come every 4 years on years divisible by 4 (1996, for example), unless divisible by 100 (like 1900 or 1700), unless divisible by 400 (like 1600 and 2000), so 1600 was a leap year, 1700, 1800, and 1900 weren't, and 2000 was.
Those things that come around every year are birthdate anniversaries, by the way. You only get one birthday, and you're really too young at the time to properly appreciate it.
If you think that CNN has gone off the deep end, check out the "We must be fair and balanced, 'cause we say so every other minute" Fox News Channel on cable TV.
"...people couldn't avoid emergency vehicles because they were unsure as to where the sound was coming from."
Yeah, well that and the fact that in the unlikely event that any of the sound of the siren got through their rolled up windows, blasting stereos, and roaring air conditioners, they couldn't be bothered to turn down the radio, roll down the window, start slowing down just in case, and look around, including checking their rear-view mirrors.
On this side of the Atlantic, especially out West in cattle country, the phrase "rustling televisions" has quite a different meaning.:-)
I just tried the PremierHazard link from post #79. What this sounds like is a siren run through an amp that's intermittent at about a 3 or 4 Hz rate. Think of a siren interspersed with the "microphone keying" burst of static which television has trained us to associate with police 2-way radios. It's very annoying, but doesn't seem any more directional than the siren itself. The directional cues probably come as much from the interruption of the siren by the noise (and then the noise by the siren) as from the noise itself.

It's been years and years so I forget which is which, but one of them, as I recall, is equal energy per frequency division (for example, just as much from 1.597kHz to 2.597kHz as from 206.0312kHz to 207.0312kHz), and the other is equal energy per octave (just as much from 110Hz to 220Hz as from 220Hz to 440Hz as from 440Hz to 880Hz). If I further remember correctly the octaves had to be related, that is, the same energy in the 110Hz to 220Hz band as in the 370Hz to 740Hz band didn't count.
Not too great on IE 5.0 when you don't let them "upgrade" Media Player to the newer, more evil version. After I set the preferences for audio only (don't want the sales pitch, just want to hear what the sound sounds like) I got a still picture and then it crashed IE. Or gave IE an excuse to self-destruct.:-)
They should probably have said spiral or corkscrew instead of spin. This happens in regular CRTs and is done on purpose. At the moment I disremember why, but somewhere I've got an old textbook or two that explain it.
The solder used to electrically and mechanically connect component leads to the copper printed circuit board traces is about half lead and half tin.
The material used as the dielectric in the several electrolytic capacitors can leak out and eat away the copper traces even while the unit is in use so it probably isn't something that you want leaching into the water supply either.
The various nasty chemicals used in the construction of the monitor and the parts that go into it are probably as great an evironmental hazard as is the monitor once it winds up in a landfill.
Not in any of the varied and several monitors which I have taken apart, and even if I'd somehow only seen the insides of the ones that don't I'd have heard about it from others who work on monitors and TVs.
There's enough weight in the circuitry external to the crt which is in the back part of the monitor to counterbalance the weight of the front of the crt (which is where most of the weight of a crt is).
Admittedly trying to lift some of those puppies may be enough to make you think that there's a lead brick inside.
Only if there is a significant charge built up inside the CRT will it work. It's that charge that attracts and accelerates the electrons toward the front of the tube to bombard the phosphor dots to make them glow. The sheilding is to block X-band radiation generated by those speeding electrons smashing into stuff.
Whenever a stream of electrons is accelerated by several thousand volts and caused to bombard a target, the collision of the electrons with that target can result in X-band radiation.
Way back in the day televisions had, in addition to the cathode ray tube with ten or more thousand volts potential on its anode, another tube, the damper diode, that also had an anode voltage in the kiloVolt range, and a law or regulation was made mandating a metal cage around that tube to prevent it from X-radiating the general area.
It's not a magnetic coil. If you turn off the electricity there's no magnetism present. It's a coil (actually two, one for horizontal deflection, one for vertical) of wire, not terribly heavy, used to generate a magnetic field by running electrical current through it (them). Unlike some coils and transformers, the deflection coils don't have a core of iron, they're more like an air-core coil. An iron core would tend to concentrate the magnetic lines of force, but in deflection coils you want those lines of force to spread out far enough to penetrate the glass envelope of the picture tube and influence the path of the electron beam inside.
The electron guns (one for each color) are part of the cathode ray tube. All the stuff inside the cathode ray tube, including any electron guns, are fairly light, being made out of thin pieces of metal. The heavy part of the CRT is the glass. The rest of the heavy part is the metal chassis and the other components outside of the CRT, especially the coils and transformers that *do* have iron cores.
Perhaps he means 48 bit color, but that's (currently) a video card function.
The reason monitors went from digital to analog in the first place was because sending from video card to monitor digitally and then converting to analog inside the monitor meant adding more wires to the cable between the video card and the monitor in order to use more digital bits per pixel.
In a traditional monochrome CRT there is one beam that is swept (deflected) across and down to get it to each dot of phosphor. A pixel consists of one or more of these dots, depending upon the resolution setting. These dots are adhered to the inside of the screen and need no other mechanical support.
In a color CRT there are trios of phosphor dots (one red, one blue, one green). There are three beams (one for each color) which are deflected simultaneously by the same magnetic fields. Again, those dots are adhered to the inside of the screen and need no further mechanical support.
There is a thing called a shadow mask which is a thin metal sheet with a corresponding hole for each dot trio. This blocks the beams from getting through except during those instants when they are aimed by the deflection fields so as to land exactly on the intended dot instead of somewhere between a couple of them. The Trinitron uses a variation of this scheme that uses rectangular holes instead of round ones, and 2 or 3 thin vertical wires to help support the very thin shadow mask.
In order to get the same brightness out of a phosphor dot you have to hit it with the same amount of energy. If you can do that with more electrons (greater current), but a lower anode voltage (resulting in less acceleration) and a power supply with lower internal resistence so that you can get more current with a lower voltage, you might be able to deliver the same amount of energy with a lower chance of X-radiation, but I'm going to have to drag out several more old books to be sure about that.
That power supply with lower internal resistance will be more expensive, however.
Thank you so much for that link. That picture is easily worth a thousand words, maybe more, in explaining to me how this new CRT differs from conventional ones. If this thing flies it could make a big difference in not just monitors but televisions as well.
I said damp patch on the floor, not wet floor, to (apparently unsuccessfully) avoid anyone thinking that there was a path for current through the water directly to the dirt under and surrounding the building. The dampness I included to better electrically couple the bare feet to the concrete
Concrete has a much higher resistance than copper wire, but it still conducts a lot better than the insulation on that wire. The National Electrical Code requires that a building's concrete foundation be made a part of the "grounding electrode system".

Amen! The idea of making Mr. Phelps the bad guy just so that Tom Cruise could be the hero of the movie still gets me steamed.
Of course we all that Barney was the *real* hero of the original televsion show.
Did you by any chance post a comment about a "Tron" remake to the nanotechnology and antibiotics story?

Gives a whole new meaning to the phrase "Italian Ice".
They've even brought in psychics!

Kate Bush? That *was* years ago.

Just explained it the other day. Go here and begin reading, and it should all be made clear.

Just don't do that standing while on a concrete floor holding a live wire, or you'll be electro-corrected. :-)
I did laugh, but really, he didn't say a thing about sticking an axe head in that bundle.
