At least to my knowledge, there is still a concept of "innocent until proven guilty."
It sounds like the RIAA is going to assert that the defendant's mp3 file was downloaded, and not ripped from her own legal CDs as she claims. To refute that argument, she will need to show that a file with the same MD5sum could be created independently.
"Innocent until proven guilty" doesn't mean you can just sit in the court room without offering any arguments in your defense, unless, I suppose, the case against you is incredibly weak. Identical MD5 hashes sounds like a strong case to me, unless she can show that those values are a coincidence.
The only way for two files to have the same MD5 hash is for them to both be encoded with the same encoder, from the same WAV file, with the same bitrate and all advanced options, and to have exactly the same ID3 information, the same filesize, and to be identical to the last bit.
If two people used the same ripping software set to all its default settings (as many unsophisticated users do), got a perfect rip off the CD, and relied on CDDB information for tagging the song, then it's possible that they got mp3s identical down to the last bit, and thus identical MD5 hashes. BUT to make this a plausible defense, you'd have to show that your rip was in fact perfect. In other words you'd have to be able to recreate the mp3 independently. If the old Napster mp3 had any ripping errors, then it would be hard to claim that the later rip just happened to have the same errors - assuming errors are essentially random.
If you want to go pre-television, I believe there is some art in my local gallery from quite some time ago that uses small blobs of paint in much the same way that inkjets use dithering of 3-4 colours of ink.

Yeah, but not just ANY wild speculation. We can achieve wild speculation based on crazy assumptions, tortured logic, and all in the lack of a single relevant datum! Geeze... don't sell us short!

Excellent point. Somebody mod this guy up.
On ABC news tonight Richard Clarke, the President's Advisor for Cyber Security, asserted that the power outage was due to a failure in the SCADA systems that monitor and control the distribution system. That's an interesting claim, especially coming from a politician and so soon after the fact. It will be interesting to see if the full analysis bears out his claim.
The author does in fact define introversion as hard-wired, much like which hand you write with. After reading the book, it's not a far leap to make -- people think and react differently. [Growing up in a family mix of very introverted and very extroverted people, it was pretty obvious to me.] So, no, technically, it's not going to be altered.
I had a chance to discuss this with a person at my company who does nothing but go around giving the Meyers-Briggs personality profile to groups who want to find ways to improve the ways they work together.
What she said about "hard-wiring" is that our natural inclinations and tendancies are indeed hard-wired, and cannot be changed. Inclinations, though, are not the same as behavior. People can learn to compensate for their tendancies and even change their behavior entirely if they need and desire to. (She also pointed out that most people don't really need to change their behavior - for most people, just understanding their personality traits, and how they're different from people with other traits, is usually enough for them to be able to interact better with otherl without having to try to fundamentally change their behavior.)
Something else that was pointed out to us is that the introvert/extrovert scale is a continuum. You can be strongly introverted, strongly extroverted, or somewhere in-between. For example, I am strongly introverted, but have some extrovert traits.
apparently hamas has already used radio-controlled model planes to carry explosives and the british, for some time, were "concerned" that the ira could used model helicopters to deliver chemical weaponry.

When you get up into the exterme draws, like high performance electric motors for R/C airplance and cars, or even full size electric vehicles, the lower resistance of the NiCad makes up for the reduced energy density in run time.
Yep, NiCd cells can REALLY dump current. Ever short-circuit a fully charged NiCd just for grins? I did this one time, with a cell that came out of an old gadget of some kind. The cells were the kind with wires soldered to either end; I stripped the wire ends, twisted them together, then stood back to watch the fun. In no time, the insulation on the wire was smoking, then bubbling and melting off. But soon something happened I hadn't counted on: the solder on the battery tabs melted and the wires fell off. At this point, I decided maybe it wasn't such a smart experiment after all and I gave it up.
NiCd and NiMh batteries have discharge curves closer to that of a standard Alkaline AA...
But Alkaline batteries have high internal resistance, so they're not terribly useful in high-current devices like my Kodak digicam. That high resistance causes the batteries to heat quickly, and because resistance increases with heat, it gets worse the longer you use the device. The voltage drop across the resistance causes the output voltage to drop, and before long it can drop below a useful voltage. In high-current devices, NiMH and NiCd batteries work much longer than alkaline batteries, in part because they don't heat as much.
This isn't just theory; I've tried alkalines in my digicam, and they don't last for more than a handful of photos, not nearly as long as my usual NiMH cells. So I can use alkalines, but only in a pinch. For low-current devices like a CD player, alkalines may last as long as NiMH or NiCd, but when they're done you have to throw them away.
NiMH batteries are great but they have the downside of losing charge very quickly "on the shelf" so you can't keep a bunch of charged MiMH batteries ready to use.
I'm using NMH batteries for just about everything battery powered in the house nowdays. NiCad's dont last as long and are very bad for the environment.
Agreed.
According to a very long article/discussion I read somewhere (sorry, can't remember the URL), NiCd batteries are easily damaged by overcharging, which tends to reduce their capacity over the life of the battery - and there is no so-called "memory effect".
I use NiMH batteries in my digital cameras and love them. I have a set of 1450 and 1600 mah AA's; 1600 was the best capacity available when I bought them, but today you can find 1800 and 2000 mah capacities.
One problem with NiMH cells is that they don't hold a charge very well on the shelf - in other words, if you charge up a set, set them aside, then pick them up weeks or months later, you're likely to find that they've lost much of their charge (can't recall how fast that "shelf-drain" occurs). So I keep one set in the camera and one set in the charger. I've had both sets of batteries about 3 years and charged them hundreds of cycles, and I think I've noticed a bit of a decrease in effective capacity over that time, but not very much. NiCd cells would have died an aggravating death by now.
The lithium-ion batteries in my iPod and Dell laptop seem to have both good capacity and shelf life, but the laptop batteries died after a couple of years and I had to replace them... VERY expensive. I hope the iPod battery fares better.

I know of at least one older form of amateur aerial photography: the Estes Cineroc, an 8mm movie camera launched as the payload of a small solid-motor rocket.

If all economists were laid end to end, they would fail to reach a conclusion. (If all socioeconomists were laid end to end, nobody would miss them.)

There is no such thing as a NiCd memory effect.
I've got a bunch of 2100 mAh NiMH AA's...
Wow, where'd you get them? Highest capacity I've seen is 2000.
