What nonsense! You've completely failed to back it up, by the way, and are misinterpreting the wikipedia article you linked to.
It is just the nature of digital, a mere sample of the original, which means it is an inferior reprodution.
You're incredibly ignorant of signal theory. When a bandlimited signal is sampled at a sufficient frequency, the discrete samples hold ALL of the information of the original signal, and when the DAC converts to analog again, the original signal is reproduced. The bandlimiting is valid because your ears are bandlimited at no more than 20 kHz, so sampling at twice that, with a little extra to accomodate the filter's slope, is all that's needed. And by the way, our world is not analog at the fundamental level; quantum theory discretizes everything. Look up the Bekenstein bound -- in a finite region of space, you can only have a finite amount of information.
As for your taste in expensive audio -- well, if you wanna compare audiophile phalluses -- I've built clones of Nelson Pass' $50,000 XA monoblocks, derivatives of Hill's Plasmatronic speakers which are as yet unbeaten in performance in the 500 Hz and above range, several DACs, and own Stax Omega 2 electrostatic headphones ($2000) for which I built a hybrid solid-state/tube amp that has 0.001% (measured by the original circuit designer; I don't own a distortion analyzer). Not one capacitor in the signal path.
Wow, what total ignorant rubbish this is. First of all, if an analog signal is sampled at twice the highest needed frequency (with others filtered away), then during the digital-to-analog conversion that the DAC chip does, the original analog signal is exactly reproduced. As for compressed sounds being rubbish, blind testing (subjects didn't know which encoding they were listening to, but could switch between them) with top-end gear ($12,000 Sennheiser Orpheus headphones) showed no one is able to distinguish 225 kb/s mp3 from uncompressed audio. It is true that many CDs were poorly mastered, and many CD players have poor performance with respect to jitter and so on. But a properly implemented digital system far outperforms vinyl. It's not just the noise of vynil, it's the limited dynamic range masking details, severe equalization that has to be applied to the signal at recording then inverted during playback, which means capacitors in the filter messing with the phase, and so on. Just because typical CDs and players are a poor implementation of the digital paradigm doesn't mean vinyl is not crap -- it is. Of course, it doesn't really matter considering the crap equipment most people own (disclaimer: I build my own).
You are right, in that if properly done, the filtering should not create a problem. Unfortunately this is almost never the case. However, a bigger problem especially in early CD players is jitter in the signal, which is well studied and is the reason why a copy you burn of an audio CD can sound different than the original CD on a stand-alone player (not an issue when played on a PC due to asynchronous buffering, though there are other sources of jitter in there). The dynamic range issue, well for 16 bit it's not sufficient to cover what humans can actually here as no 16-bit DAC chip manages the theoretical maximum for the format. This another reason for 24-bit formats.
Nah. The newspaper's webmaster should just learn how to use the 'NOCACHE,NOARCHIVE' tag.
Bullshit. That's like saying to someone who had hidden camera images taken of them in the washroom that they should have worn a sign saying "Don't photograph me"
Bullshit. You're only a sociopath if you abuse the trust for the action itself, to hurt others. There's nothing wrong with abusing the trust to gain something else, if the gain outweights the risk of being caught times the consequences of being caught. Simple cost-benefit analysis.
Bacteria win by biomass, adaptability, number, diversity of environments occupied, etc. It is the multicellular organisms that are highly specialized to niches and fragile in comparison.
Nonsense. As has been pointed out numerous times, ray tracing scales logarithmically with scene complexity. As number of triangles increases, ray tracing becomes faster at some point than raster algorithms. The article even gives specific numbers.
The problem, of course, is that the myopic moderators have caused your initial post with the incorrect assertion to be at the top, which means that most readers will come out of this misinformed.
This is not quite true: "This is related to their extremely complex social structures". Conscious self-awareness is not related to intelligence, as Damasio's neuroscience research on the subject shows. It is a more basic feature of the brain that is at a lower level than the neocortex intelligence, and is present in at least all mammals and probably birds.
Piracetam and it's several derivatives have been very effective for me, improving memory and concentration. Sure, caffeine does that too, but it lasts only a short time, and has negative side effects in larger doses.
Regarding sleep, consider drugs like gaboxadol and the experimental CX717, which go far beyond modafinil (brand Provigil) and it's new relative armodafinil. Gaboxadol promotes deep sleep in the sleep cycles, and makes shorter amounts of sleep more restorative. CX717 reverses the effects of sleep deprivation; indeed, it seems to be very close to a substitute for sleep.
Strange. I flew out of Seattle and carried with me a self-made headphone amplifier, with the enclosure being just a small tupperware container. They didn't give a shit.
Funny you should mention fusion. All the money wasted on wind/solar/wave/whatever should be added to that spent on projects like ITER (iter.org). Of course, the environmentalists secretly don't want fusion to succeed, because what their true goal is to impede technological progress, which is what will happen if we end up using wind/solar/etc given the amount of power these can provide vs the growing energy needs as developing countries industrialize.
I found that the rubber gaskets used to mount hard drives in some cases are woefully inadequate in insulating the case from hard drive vibration. I took my Raptor out of the bay and simply glued it to an inch-thick piece of high density foam on the floor of the case. Now head movement is virtually inaudible with the case closed.
In the end, watercooling everything including the powersupply has been my only fully successful solution in silencing a PC overclocked about 20%. Removing all fans, trading for a single centrifulal blower, simplifies the issues of silencing by moving it to just one point, and building a silencer around the blower and water pump is not difficult.
I used SolidWorks in school for making stuff to be printed by the rapid prototyping 3D printer. I sure hope there's a better program than this, the interface is a piece of shit.
Trillian's IRC plugin is the crappiest IRC client ever. I mean, it doesn't even support fserve, for starters. And if you're in a ton of channels all the time, you better turn of logging, or as logs start getting larger, it slows down to a crawl.

and analog is better than digital.

You missed something. Feelings of guilt and remorse result in lost productivity, which can easily tild the inequality.
Why should they be the ones to take action? On the contrary, it should be opt-in instead of opt-out: the tags should be DOCACHE and DOARCHIVE.

You expect too much, ethically speaking, of the average slashdotter.
this species simply uses a genomic swiss army kit
Why did you put the word "simply" in there, when it makes no sense in that context? Feeling extra verbose today?

Good supersampling is not just 'averaging'; the rays are weighted by some filter like a Gaussian or Lanczos etc.

I don't get it.
