A normal recording counts the pulses over about 45 microseconds (for 44.1 kHz) to get a 16-or 24-bit wide number IIRC
The sample width size in a CD is 16 bits. But converting the sigma-delta bitstream to PCM is not simple counting - it's a decimation filter with a sin(x)/x impulse response. Counting would be equivalent to using a filter with a square impulse response which has pretty poor out-of-band rejection.
Storing the raw bitstream instead of decimating it to PCM sounds like a good idea - it's the highest possible quality. The problem is that it's not practical to perform any kind of digital signal processing on this bitstream (e.g. equalization). I prefer the approach of the Audio Renaissance DVD-Audio format - stay with PCM, but increase the sampling rate to 96kHz and sample width to 24 bits + nonlossy compression.
I won't be surprised if many SACD players will actually decimate the sound down to standard PCM to perform graphic equalization and then play it back through a PCM DAC...
It would be interesting to correlate this map with an infrared thermal scan to detect geological hot spots - you might find underground liquid water that can be pumped instead of mined.
No. Anything but a direct replacement would require significant design effort, debugging and testing and you can never be quite sure that subtle differences won't cause problems later.
Besides, it's much cheaper to scavenge:
A promising lead turned false. Finally, a board was found. It cost $500.
"That's very inexpensive," Mr. Renfroe said. "To hire a design engineer for even one week would cost more than that."
When I read about the different disciplines represented on the team (anthropologist, archaeologist, linguist, etc) my first reaction was "hey, they should also pick a science fiction author". Well, it looks like they did...
Every single atom of Uranium in the Earth is going to decay - producing all the same radioactive wastes whether mankind is involved or not.
Most nuclear fuel is artificially produced Plutonium, not naturally occurring Uranium.
Uranium 238 has a half life of over 4 billion years. When converted in a breeder reactor to plutonium and subsequently used as fuel it produces a variety of isotopes with half lives that are too long to decay rapidly and yet too short to spread their emission over billions of years at safe, low levels. It these pesky midrange half-life isotopes that the site is designed to handle
Technically, the total amount of radioactive waste is the same whether you include human nuclear activity or not - but only if you calculate the total over billions of years. In the range of a few thousand years the results are more disturbing.
A study was conducted on children for labelling of drugs and other poisonous household stuff. It turns out that children associate the skull and bones with pirates, not with poison. For them it's cool, not a warning. A green face looking sick was suggested as an alternative.
Because getting involved in it is a sure way to lose funding, face ridicule and disciplinary action and generally be shunned by your peers.
I find it interesting that university research in this field is suppressed and all the interesting results come from places like the Navy, national labs and private research.
I don't know if it's fusion or not, but there probably is something unusual happening in those palladium electrodes.
"Now, if I may digress momentarily from the mainstream of this evening's symposium, I'd like to sing a song which is completely pointless, but is something which I picked up during my career as a scientist.

The LAHF instruction loads some of the condition flags into the AH register. The bit positions emulate the flags register of the 8008 processor so LAHF+PUSH AX is equivalent to PUSH A. This instruction was designed to support automatic translation of 8085 code to 8086.
All x86 processors still support this instruction (yes, that includes your latest Pentium)
the problem is that in the usa, there is a history of both legal and illegal discrimination against people of darker skin. the beard analogy doesn't fly for this reason--people with beards weren't ENSLAVED
Oh, the european colonial powers benefitted from slave labor no less than the american south. They were just clever enough to keep the slaves in the colonies and import the goods instead of bringing the actual slaves to their beatiful little countries. The British, the French, the Spanish - they were no less racist than the southern slave owners.
Rowling's books are, I believe, so popular because they are both accessable and marketed to relative non readers
Rowling's books are mostly popular because they are popular. Just like celebrities are well-known for their well-knownness. It's a positive-feedback phenomenon. It's difficult to predict such phenomena. It usually won't happen unless it's something that people like, but the fact that it's 100 times more popular than some other books doesn't mean that it's 100 times better.
I expect you're going to get flamed for calling Peter Jackson "fan boy". Actually, I agree with this observation, but I still think his film version of LotR is great. PJ's fanboy enthusiasm and dedication goes a long way to make up for the fact that he's not exactly the world's greatest director.
In softmodems the hardware is little more and A/D and D/A converters - the software driver needs to perform complex signal processing algorithms. The resources required for developing and testing these algorithms are probably beyond the capabilities of open source developers.
I don't think a soft WiFi card will continously receive bits and let the software do everthinng else - the hardware should still be capable of decoding packets, matching the MAC address and detecting CRC errors. The software will need to do the encryption/decryption and the algorithms for network detection and handshake, transmission speed power control and perhaps some other housekeeping stuff. This doesn't sound so bad.
Actually, in a card without firmware there may be less places for sneaky undocumented features than in a card that simply exposes the bare hardware capabilities to the host.
the roots of George Lucas' empire lie not in "The Odyssey" but in classic and pulp 20th century sci-fi.
Is there anything wrong with that? Homer's Odyssey *is* the fantasy pulp of the 8th century BC. Opera was the equivalent of, well, soap operas and even Shakespeare was just popular entertainment. Only much later they have been canonized as "high culture".

While Mallett acknowledges that sending a person through time may require more energy than physicists today know how to harness, he sees it merely as "an engineering problem."
It's like claiming that for an algorithm with exponential complexity it's just "an engineering problem" to build a computer that can run it in reasonable time.

UVmarking pen, and an LED flashlight in her care package.
In order for the UV marker to be really effective, add an Ultraviolet microlight. Together they can be very effective against, um... misplaced items.

Second, which is not so obvious. We only need to send enough oxygen for the trip there. Why? Well, ice is water, water is H2O
2 parts Hydrogen, 1 part Oxygen.
Umm.. why bother to make oxygen from water when the martian atmosphere is made of CO2?
1 part Carbon, 2 parts Oxygen.
Pumping the atmosphere is much easier than mining ice.
The original spacewar game is available here as a java applet.
It actually runs the original PDP-1 assembler code in an emulator.
With computers, it's not really a problem since nothing really crucially depends on getting more powerful computers all the time.
Oh, yes there is - the profit predictions and stock prices of several big companies.

Run away. Fast.

Naivete is the opposite of wisdom, not intelligence.
Only if you equate wisdom with cynicism. Being cynical never got anyone to the stars.
I'm naive, and damn proud of it.

In such a small country almost nothing is beyond visual range.
The CDROM drive looks for extra information which is not described by the Red Book but not disallowed by it either.
I'm not saying I like what they are doing, but it appears to be CDDA compliant so they can use the logo.
