Landmarks, my good friend. Find something special, such as one of the fans pushing air through the system or an unusually shaped segment and you can easily pinpoint your location in ducting (I'd assume).
I know a cooling technician who once got lost in a company's ductwork. Crawled around for an hour or two, found a spot where his cell got a bit of reception, and called up someone with a map to guide him out.
Not neccessarily. If he was using a lead point or mercury filled bullet (assuming he was just out culling the population, not hunting for food) you have what's called an exploding bullet that can cause significant damage. Look back a few comments - there's a good explanation, along with the claim that a.308 with such a bullet can cut a person in half.
Ok, but you also have to consider the fact that they'd send the shuttle up there anyway without gold to haul, so assuming you don't have to bring anything back it's a free ride. Otherwise, just don't use the shuttle - stick a launch capsule with heat tiles on a refurbished saturn, stuff the gold in there, and just drop it down.
There's most certainly a way to break even in that situation. Hell, worst case scenario you glue heat tiles to the gold itself and let half burn up on reentry - you've still got the other half as almost pure profit.
it would cost more than $800USD to put ~$300USD of gold into orbit. His conclusion was that if gold were available in low-Earth orbit, it wouldn't pay to go get it.
Maybe I'm misreading something, but isn't it significantly more expensive to put something into orbit than to get it back down, and if so, what's the cost of putting gold into orbit got to do with going there to mine it and bringing it back?
It may cost $80 billion to get $30 billion of gold into orbit, but if it only costs you half a billion to launch the shuttle into orbit then it is most certainly worth going to get it.
Fine if you can let it burn for a bit, but if the cops are busting down your door when you hit the ignition and they immediately put the fire out, there's a chance the platters will survive. If you can damage the platters or heat them enough to demagnitize them, you win. Otherwise they can just stick them into another drive and read everything out.
You see, that's why I love foreign movies - they're based on different stories.
In my opinion every culture has a collection of plots, characters and situations that everybody generally knows, and that in some way are incorporated into most stories that come out of said culture. The thing is, each group of people has a different set, so when I watch a chinese movie, for instance, even if it is a rehash of old tales it's a completely new story for me.
Of course, just try to find them in the cinemas anywhere...
You have indeed created motion. However, energy cannot be destroyed and nothing keeps moving for ever (friction et al), so eventually that motive energy will also be reduced to heat. Just think about it - there's no residual motion energy in the coat hanger after it's broken and you're holding it still, but the energy must have gone somewhere.
Bit flipping, light, motion, whatever - the energy used eventually reduces to heat energy. The only difference between a 5KW Beowulf cluster and a 5KW heater is that you can usually direct the heater.
Most certainly fitting for those who purposely leave their access open. There is also the group of people who don't know any better - their fountain was installed by linksys and they don't realize or don't know how to turn it off.
It's an issue of user education and saner defaults. Plug and play is a bad thing in my mind - the router should not be functional until the owner has set up his own password and security details.
Well, you're one of the lucky people with unlimited service. In my case, although my cable modem isn't metered, it does have a cap which I have to pay to raise, which is effectively the same thing.
I agree it's not nice to take advantage of someone who doesn't know any better. On the other hand, assuming your a decent person and your neighbor is a decent person, do you think he'll mind if you use it for a moment to check email and grab a few stock quotes? Firing up bittorrent is a nono, but I personally wouldn't mind sharing my access a bit.
Our cable modems aren't metered, but I know mine has a bandwidth cap and I have to pay to raise it, which is effectively the same. Fat pipes don't have a cap, but the larger the pipe the more likely it's metered is what I've always heard.
Indeed I would be ticked off if my neighbor watered his lawn, washed his car, filled his pool etc... with my water, as that would become a significant portion of my bill. This is equivalent to connecting to someone's wifi and firing up bittorrent. But I'd have no problem with him using it for a moment (he went for a run and wants to hose himself down, for example), which is similar to logging on for a minute and checking email. As long as they don't use up a significant portion of my bandwidth I don't mind sharing a bit. And if I don't want someone using my access, I turn on the security features.
Your biking analogy is flawed - him using their unsecured wifi does not prevent them from using it, whereas stealing someone's bike most certainly does. The TV is better, but again you're taking up a spot in their couch.
The most accurate analogy I've found is watering your lawn with a hose attached to the neighbor's faucet. It doesn't preclude them from using water at the same time, but it does reduce their available pressure and will cost them more...
It's not the rumble of the motor itself that's the biggest issue (although that also could be picked up by the needle and cause distortion) but the variations in speed of the motor. What the article doesn't say is how smooth the motor and how accurate the controller is. The human mind is very sensitive to jitter, so if your motor's speed oscillates you'll quite likely hear it in the music.
Think of it as Frequency Modulation - the frequencies in your music are modulated by the error on the motor's speed.
I was brought up on querty, but I recently moved to Europe and had to deal with the prevalence of azerty keyboard here. I've discovered that, barring symbols and such, if you can type blind it is not at all hard to learn multiple layouts. It's a bit like multiple languages - you just have to know which one you want and the rest flows naturally.
I still prefer querty, but if I'm faced with azerty all it takes is a minute or two to recall the differences. It'll probably be a bit different with dvorak, as the layout is significantly different (azerty and querty are very close), but it should be doable.
It doesn't need polishing, it needs scrapping. I'm no ham (although I'd like to get my license some day) but I can understand the need for multiple communication systems. Whatever happened to not putting all your eggs in one basket?
Maybe when wifi has blanketed the world with access, but until then keep the noise out of the existing radio systems. We need them for weather, for emergency, and god knows what else.
Heck, I can't even get AM radio on the commuter train any more due to all the noisy electronics. Can't stick to FM either, seeing as a 20min ride carries me out of reception.
Sorry, but they hadn't. The article clearly stated that although they had the administrator password and had removed the access restrictions on their own computer, at no time was the central server in danger.
Thing is, although there's plenty of that stuff around, not everyone gets it. Until a year ago I received no spam whatsoever, and I have yet to receive a mail virus. As for phishing, I just received my first one today.
There are plenty of people who'se inbox isn't totally bogged down and corrupted. It's those that still trust email.
I'd say it's more analagous to calling people up and posing the same question. You don't expect your bank to accost you on the street so you're naturally suspicious of anybody who does so. A phone call is not uncommon, however, and people become significantly more trusting - proven many times over by social engineers.

Of course not - that's not what I was responding to. I was refering to the grandparent's remark that gasoline would be sufficient...

Apparently it was a new computer system and they hadn't been properly trained on it, so it's a bit more than not being able to use a keyboard.
