But what you've missed is that it takes as much energy in fossil fuels to produce a gallon of ethanol as is released when you burn it. The benefits of ethanol as a renewable energy source are very debateable. I'd bet bio-diesel is a lot more energy positive though. It is going to be extremely difficult for any renewable source to take hold until all the non-renewable sources are gone.
Not true. We're probbably never going to run out of fossile fuels, it's just going to become increasingly expensive to get them. Not all fossile fuels have equal costs in getting them out of the ground and into a useable state. Canada for instance has a trillion barrels of oil in the form of tar sand. They're very costly to extract into a useable form though. The point is that as fossil fuels become increasingly expensive renewable sources will become econmically viable. The costs associated with renewables will also likely only go down as more money+research gets pumped into them from the profits of usage.
This is actually one of the reasons that OPEC doesn't want high oil prices. High oil prices only encourage investments in other energy sources, which eventually only undermines oil prices.
Most people can pretty easily memorize song lyrics and the sounds of a song, but yet the digits of Pi are incredibly hard to memorize.

I equally can't explain in a nice rational way why it's easy to memorize a song, but to anyone that can it doesn't need any more explanation.
Really I'm trying to avoid the whole semantic argument of what a "sense" is and merely trying to distiguish something that says something that tells you about the outside world with something that tells you about your own body. Define the word "sense" however you like, but there is a difference between the source of information. The 5 traditional senses have a data source of the outside world. Really, when it comes down to it why not consider you own emotional state a sense?

2) Would someone be willing to pay $38 million to get insider info on a merger between two banks - each worth over $10 billion.
Except SHA-1 isn't an encryption scheme, it's a hashing algorithm. For your 38 million you could construct an machine that would create two random messages that hash to the same value. Totally useless. Really what you want to do is find a message that hashes to the same value of a specific message. Or even better you'd want to create an arbitrary message, tack on some header or footer and have that hash to some chosen hash.
If I understand message signing and digital signatures, an attacker wants to make it look like they're the intended target. Say I send a signed message to my bank saying "please transfer $1,000,000 to account 123456". An attacker wants to generate a message like "please transfer $1,000,000 to account -attacker account number- that will hash to the same value, so he/she can use the same signed digital signature. The 38 million dollar device won't be able to do that in 56 hours, I doubt you could do it in 56 years (and I highly suspect it would take MUCH MUCH longer).
Other possible ones would be hunger, thirst, diziness, nausea from food poisoning, etc.
The difference is those aren't senses of the outside world, but rather feelings about the state of your own body. That doesn't mean they aren't relavent or as "real" as the normal 5 senses, but they aren't really a sense in the same way that smell or sight is. I can't say to someone else "hey, do you feel that hunger over their?"
But the question isn't do you think YOUR town should have WiFi service, the question is should the state remove the possibility of any town or government entity to supply network access? Why does the state think they need to trump local governments?
Personally I don't think most cities should get in the business of supplying wide-scale internet access. Maybe in some places it'd work, but in general I don't think it would. Small scale Wi-Fi internet access, at say an Airport, library, town-hall, etc makes a lot of sense to me. Why should the State prevent local governments from doing this? Sounds like special interest groups want to cash in by having to sub-contract with said public places to provide network access.
I do buy my water from my town (Barnegat, NJ).

I don't know anything about your local water supply, but in general people have gone crazy in this country about the purity of water. By and large it's an irrational fear since water quality of public water supplies is closely monitored. I do however filter my water with a cheap Britta because of the unknown factor of lead leaching from my plumbing, and I don't like the taste of chlorine.
Obviously you're the one who's ignorant here. Anyone who knows basic history knows that WWI ended in 1918, and the depression began in 1929. That's 11 years.. 11 years of enormous economic expansion called the roaring 20s. If you want another example the 50s were also an enormous expansion of the US economy. If you'll remember the 50s were preceded by another little war called World War II. Obviously WWI wasn't a direct economic cause of the depression.
The question is quite irrelevant though. The cause of the great depression is as relevant to what could cause another depression as the cause of the Chicago fire causing is to causing a fire. Martial law, masses of infrastructure damage, huge amounts of death, and loss of consumer confidence are all "bad for business" as they say. If you don't think that's a harbinger for another depression it's you that needs a serious lesson in economics.
Well, I for one am not the least bit worried about New York City or San Francisco being vaporized. I live in the Mid-West. In neither case would the fallout drift overhead.
Then you're a fool. A major US city being destoyed would be devastating to the economy. Ever heard of the great depression? If a million people were killed in NYC we'd all likely be thrown into something like the depression.
From what I've seen of Florida, the food is mostly poor. Don't take that as a reflection of the US though. San Francisco, by comparison has excellent food (though it is a bit expensive).
The thing thing that most Europeans and Britains don't realize about the US is how large and diverse it is. There are large scale regional differences between the east, west, south, and midwest and many differences between bordering states in the same region. Fashion sense for instance is entirely different in New York than it is in Florida. In other words, don't judge the entire US by a visit to a single state.

Most courts have ruled (like it or not) that employees have few expectations of privacy in the workplace. (with the exception of obvious places like bathrooms). This means employers can monitor just about anything an employee does in the workplace.
Privacy laws are based on a reasonable expectation. Kids don't have the same expectations of privacy from their parents that adults do from other adults.
This case is the equivalent of a woman hiding a camera in her own bedroom to catch her husband in the act, only to be told it's inadmissable because they didn't know they were being taped.
Except for the fact that the husband doesn't have a reasonable expectation of privacy from his wife in their bedroom. A phone conversation, or an email chat is obviously different.

In realistic terms, would you have predicted such rapid advancement in computer processing power over the last 9 years?
Only a fool would have ignored the doubling of processing power every 18 months that's gone on for more than 20 years. but encryption schemes are not specifically meant to protect things forever, just the length of time that the information contained could be damaging in the 'wrong hands'
As someone else pointed out, SHA isn't an encryption scheme. Nevertheless you're technically right, but effectively wrong. SHA was designed to be resistant to brute force attacks for quite a long time. 160 bits is quite hard to produce a brute-force attack, so it being broken after a mere 10 years is extremely unexpected.
Am I just out of the loop... Pretty much, yah. 20,000*10,000 is 200 million dollars. That sounds about the right ballpark for a heavy-lifting rocket into geo-stationary orbit.
"should" in this context means will it be advantageous for Oracle? Kinda like every other time someone asks the question should. "Should I buy stock X?, if you benefit from it more than not, yes".
My answer is that they probbably will, since as dual-core processors become the norm Oracles customers will get more and more hopping mad because Oracle will look more and more like the robber-barons they are. What happens when there's 4 cores per CPU? Say Oracles closest competitor can handle half the transactions/sec that Oracle can on the same hardware, but don't charge per Core. Well, at 4 cores that competitor can probbably handle somewhere near twice the load that Oracle can. Time for Oracle to re-consider it's pricing model.
