But the problem is that there needn't be only one copy. Sure, you have to destroy the original, but you can make TWO copies instead of just one, and they would both be you. The illusion that your consciousness actually exists and isn't just a biological machine in your skull would be hampered a bit.
It was my understanding that the hard drive itself is supposed to have its own ecc codes on every block, and they're checked by the firmware and transparently marked as bad and the data moved to another block if an error is detected. So in most cases, an extra software layer of checksums or codes would not really be necessary, and that's probably why there's only that one by Sun that does that all those others mentioned. Your hard drives must really be in rough shape if data is actually getting corrupted on them...
That, or because you hadn't accessed the file in years, the drive never had a chance to detect the errors before it's too late. Hmm. But it was also my understanding that if a block goes bad unrecoverably, it's not allowed to be accessed at all, and the application that's trying to access it will usually hang. I've had that on an IBM Deathstar once - it's how I knew it was time to dump everything off of it and put it on the shelf as an antique.
Minor nitpick. Intercoolers do increase the volumetric efficiency of engines, and therefore the power. However, they *decrease* the thermal efficiency (for a given compression ratio) and therefore the fuel efficiency, as they throw away heat. Internal combustion engines, very nearly being heat engines, run on heat. It's all a tradeoff.
I don't understand. You want to do coding and system administration, but you're taking engineering? Programming is what you live and breathe, so you think engineering is what you want? It seems to me that you should just keep doing what you already are. For coding and system administration, you don't need any calculus or differential math.
All wrong. The Spitfire Mk. I had the eight rifle-calibre machine guns in the wings because the designers, and the RAF, thought that they would be adequate. Note that the Hurricane had the same armament. When these fighters fought the Luftwaffe over Britain, the 109's were armed with two rifle-calibre machine guns in the nose, and two 20mm MG FF cannons in the wings. The 109 was superior to the Hurricane in all but turn rate and durability, and roughly a match for the Spitfire, but even so, Hurricanes shot down more 109s than Spitfires did. The British fighters managed to make do with their inferior armament, and the RAF won the Battle of Britain.
It wasn't until much, much later that the 109G-6 was armed with the MK 108, and even then not all planes had it, as it wasn't ideal against fighter planes. It had a slow muzzle velocity and only 60 rounds could be carried, so even though it could blow up a plane with a single hit (or two), it took a good shot to actually hit a small, fast moving fighter with it. It was intended mainly for bombers. Many other 109s had the MG 151 20mm cannon instead, which was often better against fighters, such as the Spitfire, which at this time at two Hispano 20mm cannons and either four.303 machine guns, or else two.50 cal Brownings - a much improved armament.
It's worth pointing out that in theory, if the OS was designed right, it would be possible to get good responsiveness out of a single-core chip with twice the clock speed of a dual-core, and you'd still have far better responsiveness with single-threaded apps or even problems that can't be parallelized (these problems do exist, and it's worrying to me that all the CPU manufacturers are having to resort to parallelism which won't scale for some things). But anyway, few OSes are designed this well, and as a result you'll notice a huge improvement with two CPUs. Although I've never used it, I've heard that BeOS was really good in that respect, and Linux as well as Windows and whatever else just suck for letting one application - or a few - slow down the whole machine.
Actually, it's registered memory that the 940 boards have to use. Both the 939 and 940 can use non-ECC or ECC memory, but the memory from one will not work with the other.
It's a shame that some manufacturers will make high-performance registered ECC memory, but they all don't care about performance of unbuffered ECC, which is what I want for my next machine...
Funny... I've been thinking of the exact opposite creation: a BSD/Linux system. It would use the BSD userland and the Linux kernel, and might be useful for features that haven't made it into FreeBSD's kernel, such as exotic hardware support, or whatever else.
The BSD packaging and userland is what I'm familiar with, but I've never used Debian. What do you enjoy about its packaging system? What does it do well?
Is she actually claiming that it's racism, or is that just the editorializing in the article? There is no evidence of that. A dress code is a dress code, even if they decide to enforce it after three years. That she didn't want to remove it because she thought that they didn't have the right to require that shows how self-righteous and self-centered she is. In fact, she made this out to be an issue of race by comparing her nose stud to a turban or scarf. She sounds like a shit-disturber to me, and that's probably why she was fired. Bad attitude.
But the problem is that it's not even a great way to store and transfer energy: it's a shitty way to store and transfer energy. It's a very light gas that leaks straight through metals and reacts with them on the way through, and even when liquefied it isn't nearly as dense as we'd want to make it worth the effort of liquefying. In short, it sucks. It's better to use methane.
Even quantum physics, although theoretically 'random', is generally predictable and reliably recreatable for a large T distribution over time.
Sir, this is true of all random events. For instance, a number randomly chosen between 1 and 10, or 0 and 2^32-1, is random, but if you take the sum of a million of these, it will be very predictable. Doesn't mean that the individual events are not random.
Something I thought would be fun would be if we could somehow declare, legally, that all those who believe that copyright should be abolished have THEIR rights to copyright abolished. That way, everything they ever produce (or ever have) is immediately under public domain.
Yeah, and all those people who currently use GPLed software in their products won't be forced to release source or use something else, unlike today. Have you not noticed the legal action about that when cases like that arise?
If no copyright is the goal, why does anyone bother with cases like that?
NiMH batteries don't have a charge memory; you're thinking of NiCads. Plus, the best NiMH batteries store almost as much energy as alkalines, and in AA format they're not too expensive due to volume and competition.
Li-ion, on the other hand, is a very expensive format due to the need for internal circuitry to protect the battery, and as a result it doesn't come in the standard sizes, which can guarantee a high cost as each manufacturer can rip you off for their own format...
For many many applications, NiMH is by far the best way to go.
Just curious - how is he a bigoted, womanising, etc etc? In which of his stories is this evident? I've only read Starship Troopers. And I liked it, but I know little about the man. I'm really interested to know more about his social views... What are they, would you say?
If your schtick is promoting advancement of technology, then you should be railing against trade-secret law, not patents. Let's say there are two airplane manufacturers, each of which has spent $xx billion on R&D to produce airplanes, and each of which has kept its results as trade secrets under lock and key. Since none of this research is public, any new competitor will have to reinvent the wheel. Since no such company can get funding to do that, the industry remains gridlocked forever at two firms.
You want to talk tyranny? That's it right there. The mere notion that anyone else should have any inherent right to research that a company funded entirely on its own is complete lunacy, and only a tyrannical government would ever attempt to enforce that. If the public wants technology, they can develop it themselves.
Uhhh... What? You want postal prices for sending cookies to increase? Don't you realize that the only reason it's so cheap and fast now is because of junk mail?
By the way, don't take this as me supporting spam. I think all spammers should be killed, but there's nothing wrong with physical junk mail subsidizing regular mail. All US Postal customers benefit from it in that way.
The fact that the observable universe is finite explains why the night sky is dark, yes. But what we know is that the universe extends far beyond what we can actually see. Think of it this way. We can only see 13.7 billion light-years away (and then only the cosmic microwave background), since beyond that, the light has not had time since the beginning of the universe to reach us. It's outside our light cone. (A google search for that term might explain this better than I can.) But it's still there. We know that the universe is one of two things: either very, very large but finite, or infinite. Two years ago, we thought it was infinite, but now it seems that astronomers are saying that it's finite. Which sucks.
OT, but astronomers are now saying that the universe is finite? It seems like just a year or two ago my Astronomy TA told me that it's likely infinite, and that does imply all that craziness with everything that is possible (that could occur in the 13.7 billion years since the universe began) has already happened, and there are parallel mes and yous and slightly different versions of us, and everything else that could ever be, somewhere is.
It would just really suck if that weren't the case. It's way too much fun to think about.
You're right about a charge inside a hollow conductive sphere causing a like charge to be distributed on the outside... I now remember that from my physics class. But, consider a microwave oven, as a poster below me mentioned. The perforated shield at the front, and all the metal surrounding it, sure do seem to do a good job at keeping the microwaves in and not out. Now, radio signals in the upper part of this frequency range (100 MHz to 2.4 GHz) are microwaves, so I wonder what will happen to a microwave source surrounded by this paint.
You remembered that a Faraday cage only protects the inside from out, and not vice-versa, and I didn't remember that. So maybe you know more about physics than me. But just because a static charge inside a Faraday cage does one thing, does that necessarily mean that microwave signals will do the same thing? The evidence that I have seen suggests that they will not.
But there isn't a reasonable possibility of harm. From what I've seen, the evidence supports that something is going on, and the risk of a certain disorder is doubled, but it is doubled from one insignificant probability (1 in 100000) to another. There is no point whatsoever in foregoing or even reducing cell phone usage when the risk is so slight compared to everyday things, like crossing the road, or driving a car, or taking a shower.

Yeah, that's true; I apologize. You did get the gist right. Early Spitfire and Hurricane armament was indeed inadequate...
I'd like to see that show that you mentioned. Unfortunately, I don't have cable. Maybe it's available on the internet somewhere...

Sir, you missed explaining one thing. What is the Aristocrats joke?

Mostly correct, except that 939 systems support ECC just fine. But you're right about them requiring unregistered RAM.

Do you not understand that that's a selfish, shortsighted way to think and act that makes people who do that part of the problem?
