What concerns me about this method of controlling this is the compliance costs. Whenever there is a tax there are forms to be filled out, reports to be filed and audits to be done.

The tax collection and remittance would all be handled by the exchanges.
Audits are trivial, since every single trade is already logged.

Well if these brokerages spend all of this money complying with a tiny tax to stop an undesirable behavior they are going to pass that on to customers.

0.03% is a rounding error to most traders.
The only people who will be thwarted by the tax are HFTs who make their money on fractions of a cent.

0.03% is an extremely small cost to pay for stamping out zero-sum HFT activity.
If we're lucky, they'll roll that money back into the SEC for better enforcement of the stock and commodities markets.

And remember, even if you have a title to a plot of land, whatever is below the surface certainly does not belong to you.

Those are called "mining rights" and they're for sale too.
It's just that most of us don't bother buying them, because there's nothing worth owning under our land.

This article doesn't talk about it, but the volcanic ash (AOL Keyword: pozzolan ash) can be found in deposits all over the world.

It's already mined commercially and it will be trivial to increase that mining capacity in locations that are far away from anywhere environmentally sensitive.

The USAF has been working on "stealth helicopters" for years. They haven't been able to make them silent, but they can make them sound like wind noise, eliminating the distinctive "whap-whap-whap" blade sounds.

The first trick is spreading the noise out over a larger range of frequencies.
You can accomplish this by changing the rotor blade spacing to reduce harmonics.
So instead of equally spaced rotors, the distance between them is unequal, which mitigates that whap-whap-whap sound.

The second big method involves actively "flapping" the rotors.
This lets you change the plane of the rotor just enough to miss the vortex from the previous rotation.
By always traveling through smooth air, you can minimize uneven pressure waves which create noise.

The rest of the tweaks are aerodynamic adjustments to the blade tips/materials/shape.
And last but not least, throttle back and reduce the rotor speed.

Even if he is lying, the fact that there's any ambiguity at all is proof that there's not enough oversight.

"and Congress is made aware of these activities." does not actually mean all of Congress was made aware of the activities.

"Congress is made aware" usually means "we told leadership and some key people on an intelligence (sub)committee."

I don't think that the Chinese will succeed for the same reasons why the French and other European nations didn't succeed initially in Panama. The Panama canal took a national interest to construct, not a corporate interest, and was driven in large part by our nation having two coasts with a whole lot of distance in between, and by our "Manifest Destiny" doctrine. Simple economic interests operated by a corporation may not be able to pull it off, especially if that corporation is there only for that purpose, as problems along the way will make it very hard to raise capital when investors don't think that their investment will pay off.

TFA doesn't really give you the full picture, so I can understand why you'd think this is a "corporate interest"
The Chinese government created a company that they own and fund, for the purposes of building, owning, and operating this canal for 100 years.

China isn't not building the canal to operate it for-profit.
The bulk of the benefit to China will be reflected in lower shipping costs.

/Most of the largest companies in China are partially or wholly government owned.

The new Mac Pro packs an unprecedented amount of power in an unthinkable amount of space. A big reason we were able to do that is the ingenious unified thermal core. Rather than using multiple heat sinks and fans to cool the processor and graphics cards, we built everything around a single piece of extruded aluminum designed to maximize airflow as well as thermal capacity. It works by conducting heat away from the CPU and GPUs and distributing that heat uniformly across the core. That way, if one processor isnâ(TM)t working as hard as the others, the extra thermal capacity can be shared efficiently among them. No computer has been built this way before. And yet it makes so much sense, itâ(TM)s now hard to imagine building one any other way.

Isn't that what laptops do? Are they not computers for the purposes of this conversation?
The only reason no one else does a "unified thermal core" for desktops is because industry standard motherboard layouts are not compatible with such a design.

From tabbing back and forth through the interactive swf, it looks like the layout is a triangle, with the 'mainboard' and two graphics cards making up the legs.
The "unified thermal core" is a hollow triangular heat sink running down the center, with a copper mating point on each face.
It also looks like the flash drive is mounted directly behind the core of one graphics card, which should do wonders for its lifespan.
There's also a 'daughter' board in the base of the case, with some undocumented chips on it.

The CPU can be replaced without complete disassembly.
You will have to remove the 'mainboard' though.

Technically impressive. Completely non-standard.
It's interesting that Apple believes 1 CPU and 2 GPUs is the future of professional computing.

It always amuses the hell out of me when people think there were these amazing ancient technologies so much better than anything modern.

There are. Concrete is one example.
The ancients also did incredibly complex things with ceramics and glazes that we haven't been able to recreate yet.

The reason for their "amazing ancient technologies" is that was all they had.
Improvements in materials science were mostly the result of accidents or brute force experimentation.
Now imagine if the combined intellectual power of the modern world was focused on perfecting only one or two technologies over the course of centuries.

As I have been exposed to this industry and have been learning what's what and what goes on, I have learned a great respect for at least THIS government agency.

The NRC hasn't denied an operating permit in 30 years.

The last permit denied was only under heavy pressure.
When the facts came out, everything ended up in court with General Electric & Contractors being charged under RICO statues.

It wasn't a traditional court case, in that it was a summary jury trial.
GE & others ended up settling because the Judge agreed that their actions were fraudulent and that they engaged in racketeering.

The NRC is a very captured regulatory body.

We can debate about extreme circumstances in which extreme measures might be used to extract information from a terrorist or whatever, but false confessions are lose/lose. No one but the career of the prosecutor/DA benefits from a false confession

So it's not a lose/lose.
Further, the benefits of forcing false confessions can accrue much higher up, as the State itself prefers to be seen as able to protect its citizens.
