Throw a bunch of orders at the top of the market
Throw a bunch of orders under the market.
Lets say you have 3 trillion dollars of pending buys and 2 trillion of pending shorts

The play is obvious.... go up and trigger the 3 trillion of buy orders and hit their stops, and then turn around and crash right through the 2 trillion of shorts.

Sure, you hand back 2 trillion to the market... but you just nabbed 3 trillion.
Take 1 trillion in profit on the aggregate.

Rinse. Wash. Repeat.

A market maker must *always* have a bid and ask price showing and they *must* buy or sell at these prices even if it costs them large sums of money.

Of course, but that's the point though.... NO-ONE is going to actually trigger these massive orders because they don't have the equity to fill them.
Yes, it's a risk that they get hit, but... who would?

Just throw some big stops on in each direction, make it look like there are market participants....

This is basically what Market Making is: Creating a bunch of pending orders that are never triggered to push the market away and into the direction they want.
Only the biggest players on the block can get away with doing this because they have billions in equity.... such as the largest 12 banks on the planet.

Always good to know that the value of all our commodities and currencies are controlled by them on a whim, isn't it?
Also good to know that they make money by default and can't really lose the game.

Go back to sleep everyone. Nothing to see here...

Why the continual one-way focus on women? Why can't we just let individuals be individuals, and do whatever they want? Ensure that there are no artificial barriers due to gender (or skin color, or hair color, or whatever), stop pushing people in directions they don't want to go, and just let people choose whatever career they want.

Ever since women could conceive children, they've never needed an excess of men to parent the human race. One (very lucky) man is all that's needed... but themselves women are the "irreplacable" part of the equation... AND they seek to remind us of this all the time.

Hence men and women have NEVER been equal and NEVER WILL BE.

There's a bit of confusion, but essentially there is a big difference to flash memory that is presented as a replacement hard disk and talks over SATA, and a flash card that talks to the computer over PCIe through a motherboard PCIe slot.

Essentially, PCIe is a darn sight faster than SATA, so when you hook up a flash drive to it, it goes at ludicrous speeds.

Interestingly, with Windows 7 at least, OEM-SLP loader method of "piracy" has remained bullet-proof. In the past 5 years it's been in use, it has always reported genuine, no altering MS binaries, and MS can't tell the difference between you and someone that bought their HP PC at Best buy.

It will be interesting to see if upgrading a OEM-SLP Windows Loadered Windows 7 maintains full "genuine" status on an upgrade to Windows 10.

If so, it's going to be a pirate free-for-all on Windows 10, just like Windows 7

Modeling the sounds after the natural vocalizations and ranges seen in kitty conversations, researchers created songs that are more enjoyable to their little furry ears.

Possibly related to the feline affinity towards long "ee" sounds at the end their given name. This is just another way to better the lives of our kitty companions.

+ - Lockheed Martin Claims Sustainable Fusion Is Within Its Grasp-> 1

Submitted by SternisheFan
SternisheFan writes: Imagine a source of electrical power that uses water for fuel, produces byproducts that are totally safe and releases no air pollution. Then imagine that once it's up and running, it'll be so portable that an entire power plant could fit into the cargo hold of an airplane. Now, imagine that it'll be running in prototype form in five years and operating commercially in ten.

The fusion is powered by a combination of two isotopes of Hydrogen, Deuterium and Tritium, both of which occur in nature and which can be extracted from water. "Our studies show that a 100 MW system would only burn less than 20 kg of fuel in an entire year of operation," a Lockheed Martin spokesperson told eWEEK. "Tritium fuel is continually bred within the reactor wall and fed back into the reactor along with deuterium gas to sustain the reactions."
In other words, the fusion reactor creates most of its own fuel as part of its operation. The Deuterium gas is simply a normal hydrogen atom with an extra neutron, creating what is sometimes called "heavy hydrogen." Deuterium can be extracted from the hydrogen obtained from electrolysis of water. This may sound complicated, but it's a process that has been routinely performed in college physics projects.
While the fusion reactor does create a radioactive byproduct, it's recycled for use in the reactor itself. There is no radioactive waste problem such as exists with nuclear fission power plants. "The waste footprint is orders of magnitude less than coal plants which require huge landfills to contain the toxic ash and sludge wastes," the spokesperson said in an email.
"A typical coal plant generates over 100,000 tons of ash and sludge containing toxic metals and chemicals each year. The first generation of fusion reactors will run on Deuterium-Tritium fuel, but successive generations would use fuels that could eliminate the radioactivity altogether," she said.
Currently Lockheed Martin is in the process of testing a magnetic confinement bottle, where the Skunk Works team has apparently made significant progress. In terms of how a fusion reactor would be created, the magnetic bottle is the primary hurdle.
If that's accomplished successfully most of the science and engineering is known. However, that doesn't mean that building the prototype fusion reactor is a done deal. Lockheed Martin is looking for industry partners to help develop the Compact Fusion reactor into a real product.
The goal is to create a fusion reactor that can generate heat to use in existing power plants, where the reactor would replace existing fossil fuel combustion. This means that existing power generation and distribution infrastructure would be retained, which will dramatically reduce the cost of implementation and dramatically speed up deployment.
The existence of cheap, portable power will transform the world in many ways. A statement from the company envisions ships and aircraft with unlimited range, spacecraft that could reduce the travel time to Mars to less than a month.
Perhaps most important to the most people, it could bring vast amounts of power to anywhere on earth, providing among other things economical water desalination to developing regions of the globe, which are not only poor, but short of clean water, by removing energy scarcity as an insurmountable problem.
If Lockheed Martin can pull this off, and given the reputation of the Skunk Works for routinely doing the impossible, I suspect it will, the results will be transformative.
While it doesn't mean free energy, it does mean that the cost of nearly unlimited energy is very low, and with unlimited energy, there's no end to what can be accomplished. To say that the Skunk Works is on the verge of changing the world is an understatement. This development could well define the future.

Yeah, the "beige brick" power supply is what put a lot of C64s out of commision. No power, no working computer!
The trapezoidal black "heavy duty" power supplies with the Commodore 64 label on top are the ones to get if you are a collector. They can at least be repaired and don't die easily.
Failing that, there have been a few aftermarket repairable supplies, but collectors mostly have them. They don't show up on ebay often at all.

There is also a company that is producing a drop-in C64 motherboard clone which uses DC power, and is more power efficient in general, and can flip between NTSC and PAL modes. You have to supply your own 6510 CPU and SID chip however.

I have a number of C64s of different vintages, including an SX64. It's a repaired brown "breadbox" that gets the pride of place under the TV because that original model is iconic. It also takes up less shelf space than the 64C models.
I still have a "lumbering hippo" 1541 that's been modded for parallel speed disk dumping, and a few spare datasettes for dumping the occasional rare tape game I come across. ...and yeah, Telengard was a lot of fun! Ok, so it doesn't compare to Skyrim, but man, back in the day.... :)

BASIC is the Computer Science equivalent of `Scientific Creationism'.
