The problem isn't just higher frequencies, which as you say getting to optical frequencies will be really hard, but not impossible. The rest of the problem is bandwidth. I can't find the source article for this, but I'd bet the bandwidth is tiny. Visible light covers and entire octave of bandwidth. I've seen zero sign that metamaterials will ever have close to that much bandwidth. Increasing the frequency just means making things smaller. Most of the metamaterials have elements that resonate at specific frequencies.
People here are very confused about the purpose of OBS. (sorry to pick on you, but yours was the smartest)
The title "Recording Earthquakes on the Sea Floor" might be less confusing if it was "Earthquake Recording on the Sea Floor". You say you need good Earth models to locate earthquakes. That's true, but the purpose here is the inverse. They are recording earthquakes to improve the Earth models. They drop a set of OBS in an area where they are unsure of the Earths morphology and use the recordings to create a more detailed model.
The source earthquakes could be anywhere on earth, land or sea. Mostly it's the angle path the wave takes that makes it useful or not. I've never seen OBS used for local earthquake. As far as I know they are too sensitive to accurately record them.
I'd be sure to cover some major concepts universal to computing: representation, abstraction, memory hierarchies, analog vs digital, etc. These are useful concepts to understand and don't involve any specific implementation.
Knowing how a hard disk works isn't really going to help anyone. Knowing it's random access, faster than a CD, but slower than memory, might help.
A few years ago AMD's advantage over Intel was just price
That wasn't the only advantage. Dell and AMD were practically across the street from each other. Now I think they are about 30 miles apart, but I can't find the facts easily.
The main thing is that this identity is central to American leftism. Thus IP became the focus of liberalism, american leftism.
At the exact same time, it became the focus of conservatives as well (in America). Luckily, those days seem to be ending and new divisions are forming. These things are far more dynamic than you seem to think. Remember who used to hate "Nation Building" and "Deficit Spending"? Don't get me started on limiting goverenment!
I believe that we in the United States have a certain right to an expectation of privacy, but at the same time we cannot rely on that expectation to safeguard information regarding ourselves. Information exists beyond the scope of your personal effects, and you cannot reasonably expect others to protect it for you.
The FBI has argued for years (decades?) that you have no expectation of privacy for numbers dialed, so police don't need a warrant or probable cause to obtain this information. Now they are upset they don't have as much privacy as they expected. Is this "irony"? I never remember the exact definition.
Everyone in the executive branch from the President on down wants to hide their actions which snooping on mine. I'm sick of it.
Why would I want to look at a QVGA image on a 105" inch screen?
You love 1/4 inch pixels.
You have presbyopia (short arms).
They needed some dork willing to be photographed wearing an EyeBud and since the whole office has been laughing behind your back since you started wearing a bluetooth earbug, you thought, "Why not?"
I always bundle my wires and keep them separate from complex electronics. They way the screeners have no trouble telling the wires aren't connected to explosives. These people have a tough job. The quicker they can tell that your bag is safe, the better it is for everyone.
In my checked bags over the holidays, I put all wires and antennas in an outside pocket of my checked bag. Power lumps with attached cords were wrapped and kept away from my hubs, etc. Since I started making an effort to help the X-ray guys, my bags have not been hand searched.
If law enforcement personnel use a zero'd drive as an indication of wrong-doing, then they would be making the same erroneous assumption.
It's not erroneous if you zeroed it between the time you learned you were going to be search and when the search took place. The article in question leaves out many useful details.
How much experimental evidence do we have to prove the Heisenberg Uncertainty Principle?
Prove? Physics/science can't prove anything. You can disprove a theory. You can show a theory predicts things, but you can never prove it true. The Uncertainty Principle has been tested many times and no one has managed to disprove it. I'm sorry, but that's as good as we're going to get.
If you are disputing that the Heisenberg Uncertainty Priciple is predictive, you clearly haven't read any basic quantum mechanics texts. It's directly tied to wave-particle duality.
Now my motorcycle gets 55MPG without even trying. Am I a conservationist? No. To most motorists, I'm a moving target and welcome diversion. Most Californians would rather talk about the environment and road congestion problems than use the best alternative to those ills available to us now.
I thought Calafornians allowed motorcyles in the car pool lanes. They can't all be as bad as you make it sound claim.
but now that some patent cases are hurting the government, maybe they will begin to listen?>
The government can't change this. The patent office, maybe, but judging by what they consider non-obivous, they certainly don't use much technology beyond a typewriter.
Only congress and the courts can change this system. Since congress accepted the courts changes (software patents), I don't expect the courts to do anything. What we need is some patents that really hurt companies with lobbyist. Until then, big companies will continue to love using patents to avoid competing and there is nothing anyone can do.
Except of course, that it's not. Linus seems to be getting pissed off that people are getting their work in *just before* the deadline, not actually missing it. If your manager told you off for submitting your work shortly before your deadline, you'd be pretty pissed off about it.
That's now how I read this: If people miss the merge window or start abusing it with hurried last-minute things that just cause problems for -rc1, I'll just refuse to merge
I read that as being upset about people missing the deadline or submitting crap right before the deadline because they aren't ready. I think a dope slap would be better for these people.
Put back together in random order so it can't be solved. Watch them sweat as their moves don't work.
Sweat? I always laughed. You wouldn't believe how many screwed up cubes people gave me. I'd say, "You swapped some stickers didn't you?" and they'd always lie. Sometimes more than once. Then I showed them how the cube is made out of solid peices with once peice having the same color on two sides and they'd admit they swapped stickers because they just wanted to finish one side. Messed peices was rarer, since most fools didn't know how to take one apart. It usually was the result of someone dropping the cube. Still, to anyone who knows how to solve a cube, it's entirely clear when it's been messed with. We're not robot following a recipe.
kind of wonder about the statistics given for the cube (43,252,003,274,489,856,000 possibilities) in the article. By my calculates there should be less than 2,730,555,762,278,400 possibilities.
I did a quick computation and got the same number as the article.
8 corner pieces in any location is 8!, but since you can't swap two corners, but only rotate three (or swap two pairs), it's 8!/2.
12 side pieces in any location in 12!.
12 side pieces in any orientation is 2^12, but since you can't flip one side without flipping another, it's 2^11.
8 corner peices in any orientation is 3^8, but since you can't rotate one corner without rotating another, the last corner is know and so it is 3^7.
8!/2*12!*2^11*3^7 = 43252003274489856000
Maybe I made the same mistake as the article, but it's not the mistake you talk about. BTW, best cube time 1 min 26 secs.
If there were UFOs "out there", at least the sort we could recognize
If you recognize it, it's not an unidentified flying object.
As a skeptic I love when people ask me if I believe in UFOs. I always say "Yes." They look at me funny until I say, "I believe people see flying objects they can't identify. I don't believe these objects are aliens tourists." UFOs exist. They will always exist. Aliens visiting Earth? lol
Liquid CO2 is pumped into the oceans and sinks to the bottom. As you say, very little CO2 will dissolve, so it can't be converted to carbonic acid. This is why they don't just bubble CO2 gas through the sea water. As you say, dissolving it would be a serios problem. How stable is this liquid CO2? No one knows for sure, a few tests have been done, but nothing large or long term.
The Feds, have to prove that the car was purchased with funds from the illegal enterprise.
This wasn't true for a long time. RICO seizures are civil actions, not criminal punishments. That means you have to prove it's more likely purchased with legal fund before you can get it back. This happened to many people and is well documented. The Supreme Court said it was ok.
Then the feds "tried" to seize a tobacco company's ill-gotten gains. Suddenly the Supreme Court changes the rules, now they have to use a criminal seizure, not a civil one. I don't know how that affects normal citizens vs. big companies. I'm not a lawyer, I just hate RICO and think if it is going to be used against little people (instead king pins as congress intended) then it should be used against the big evil's in our country.
It's never a problem in the US, altough if you really want to keep a set, it's nice to ask them to load two pieces of film so you can keep one and they can keep one. It costs a tiny bit more, but then are both full quality origionals. I have to do this every couple years for medical clearance and no one cares one bit.
That's pretty close to what was done in the US, but the list just kept getting shorter. When it turned out the last place on the list, Yucca Mountain, was unsuitable due to active volcanism, they decided to ignore the geologists.
Personally, I'm in favor of the idea of making a national monument, so people will not forget what's inside. There's an article about that somewhere. . .

Higher freqs?

I guess the trolls have finally turned you into one. Sad.

I'd suggest dressing as an '&'. Just don't ever tell her you have a severe headache.

Well written, inspite of the over simplification. Earth Day is a great example of what you are talking about.

It's not quite fair to compare the LX to the hybrid. The hybrid is as fast and as nice as the top of the line Accord (I forget the letters).

Ok, it's like leaving your car keys in your car and being liable for someone driving it and causing damage.
