The design department, some 37 members strong, came up next. Class designers, profession designers, itemization designers, level designers, event designers, encounter and lead designers are all grouped here. Brack points out the multi-disciplinary nature of the level creation team. They use WoWEdit to incorporate art assets and create the zones in the game. The events team is responsible for not only holidays like Hallow's End, but also static world components like the city of Dalaran and the new and popular Argent Tournament. Over the years, the team has created some 70,000 spells and some 40,000 NPCs.
The Blizzard Online Network services group is Pearce's next focus. A huge group, they have data centers from Texas to Seoul, and monitor over 13,250 server blades, 75,000 cpu cores, and 112.5 terabytes of blade RAM. He points out the picture of the GNOC in their slideshow, a data core that even has televisions tuned to the weather stations. They use those to ensure that conditions of the data center are up to their standards; with only a staff of 68 people they ensure connectivity across the globe for the numerous WoW servers.
Our tribute to Michael Jackson, ironically, consists of a list of the best covers we've found on youtube by average, acoustic artists who decided to cover Michael Jackson as a tribute to his death. In our opinion, most of these renditions are notable not for their synthesizer content, but for the fact that when you lay most of Michael Jacksons' songs bare, down to something as simple as a voice and a guitar, you are left with the original songwriting that really he should be remembered for – pure, simple and brilliant, even at a very young age. Synthesizers simply became a tool to help bring that talent to the forefront, with such well written songs. Without further ado – here's our list of best Michael Jackson Covers on Youtube today.
However, where Thomas and I disagree is what to do with the money. Increasing taxes is the 3rd rail I always try to avoid -- regardless of the good intentions -- so I would rather drop the income tax. Have the income tax indexed to the gas tax -- the more money we raise in gas tax, the less we pay in income taxes that year. If we raise the gas tax we are going to affect the economics of much of the country and we need to compensate. Food is going to be more expensive, commuter communities are going to be pissed, etc..
Such a tax would make our economy healthier by reducing the deficit, by stimulating the renewable energy industry, by strengthening the dollar through shrinking oil imports and by helping to shift the burden of health care away from business to government so our companies can compete better globally. Such a tax would make our population healthier by expanding health care and reducing emissions. Such a tax would make our national-security healthier by shrinking our dependence on oil from countries that have drawn a bull's-eye on our backs and by increasing our leverage over petro-dictators, like those in Iran, Russia and Venezuela, through shrinking their oil incomes.
In sum, we would be physically healthier, economically healthier and strategically healthier. And yet, amazingly, even talking about such a tax is "off the table" in Washington. You can't mention it. But sending your neighbor's son or daughter to risk their lives in Afghanistan? No problem. Talk away. Pound your chest.
What exciting about this is that they can produce an amazingly large number of cells with a very low material cost. They are concentrating on utility grade panels right now (which is exciting enough) but I can't believe that this is just the first step towards low cost, decent, panels for residential use. Their tagline from their company website is "Technology for Profitable Solar". Other sources: MIT Tech Review. Univ. of Texas has also developed a spray-on solar cell production process.
At 16.4% efficiency, our foil cells represent two world records in one: It's the most efficient printed solar cell of any kind (all semiconductor and device technologies) as well as the most efficient cell on a truly low-cost metal foil (with a material cost of only a cent or two per square foot and mil thickness).
The nuclear reactor and steam generator, also known as the Nuclear Steam Supply System (NSSS), is a self-contained assembly of reactor core and steam generator tube bundles within a single pressure vessel. Throughout the design, every effort was made to employ existing off-the-shelf technologies to minimize, and in many cases eliminate, the need for additional research and development. The primary coolant (water) is moved by natural circulation, eliminating the need for primary coolant pumps and external power. The NSSS and the passive safety heat removal systems are housed within the compact steel containment.
The NuScale reactor operates using the principles of natural circulation. No pumps are needed to circulate water through the reactor Instead, the system uses a convection process. Water is heated as it passes over the fuel or core.
Water in the reactor system and the Steam Generator system are kept separate. As the hot water in the reactor system passes over the hundreds of tubes in the Steam Generators, heat is transferred through the tube walls. Water inside the tubes turns to steam. The steam turns turbines (7) which are attached by a single shaft to the electrical generator.
#3 Transparency would be a core element of our journalism. One example of many: Every print article would have an accompanying box called "Things We Don't Know" -- a list of questions our journalists couldn't answer in their reporting. TV and radio stories would mention the key unknowns. Whatever the medium, the organization's website would include an invitation to the audience to help fill in the holes, which exist in every story.
#6 We would refuse to do stenography and call it journalism. If one faction or party to a dispute is lying, we would say so, with the accompanying evidence. If we learned that a significant number of people in our community believed a lie about an important person or issue, we would make it part of an ongoing mission to help them understand the truth.
The film was chosen to open the Toronto Film Festival and has its British premiere on Sunday. It has been sold in almost every territory around the world, from Australia to Scandinavia. However, US distributors have resolutely passed on a film which will prove hugely divisive in a country where, according to a Gallup poll conducted in February, only 39 per cent of Americans believe in the theory of evolution.
Movieguide.org, an influential site which reviews films from a Christian perspective, described Darwin as the father of eugenics and denounced him as "a racist, a bigot and an 1800s naturalist whose legacy is mass murder". His "half-baked theory" directly influenced Adolf Hitler and led to "atrocities, crimes against humanity, cloning and genetic engineering", the site stated.
Here's a good compilation of the footage from 9/11 on Youtube. Boing Boing also has an excellent compilation of blog entries and some prophetic words from Dan Gillmor and John Perry Barlow.
Rated output of 2.5 kW and maximum output of 4.3 kW. Various sail assembly sizes available ranging from 4'h x 8'd to 6'h x 12'd. Can be utilized in most wind conditions. Power generation in as low as 4 mph of wind. 3.6 kW inverter system. Ideal for eliminating peak usage in homes, hybrid installations, back-up power, remote power, or installed in arrays along roof lines for a great architectural presence.
Most automakers displayed concept or production vehicles demonstrating their advances in electric-car technology, which has emerged as one of the dominant themes of the show. Volkswagen revealed an e-Up electric show car along with new sporty cars loaded with horsepower, and PSA Peugeot Citroen showed an electric car based on Mitsubishi Motors Corp.'s i-MiEV, already on sale in Japan.
... Renault, along with its Japanese affiliate Nissan Motor Co., has outlined plans for the most aggressive rollout of electric cars. Carlos Ghosn, chief executive of both Renault and Nissan, said Renault's electric cars would be priced so that the cost of ownership would be similar to or less than the cost of owning a diesel-powered car in Europe today. Diesels cost slightly more than gas-powered cars, but provide much better fuel economy.
It turned out that children who received conditional approval were indeed somewhat more likely to act as the parent wanted. But compliance came at a steep price. First, these children tended to resent and dislike their parents. Second, they were apt to say that the way they acted was often due more to a "strong internal pressure" than to "a real sense of choice." Moreover, their happiness after succeeding at something was usually short-lived, and they often felt guilty or ashamed.
In practice, according to an impressive collection of data by Dr. Deci and others, unconditional acceptance by parents as well as teachers should be accompanied by "autonomy support": explaining reasons for requests, maximizing opportunities for the child to participate in making decisions, being encouraging without manipulating, and actively imagining how things look from the child's point of view.
Another thing you can try that may help increase TCP throughput is to increase the size of the interface queue. To do this, do the following: ifconfig eth0 txqueuelen 1000
I've seen increases in bandwidth of up to 8x by doing this on some long, fast paths. This is only a good idea for Gigabit Ethernet connected hosts, and may have other side effects such as uneven sharing between multiple streams. Also, I've been told that for some network paths, using the Linux 'tc' (traffic control) system to pace traffic out of the host can help improve total throughput.
In a scathing report, he concluded that investigators in the Willingham case had no scientific basis for claiming that the fire was arson, ignored evidence that contradicted their theory, had no comprehension of flashover and fire dynamics, relied on discredited folklore, and failed to eliminate potential accidental or alternative causes of the fire. He said that Vasquez's approach seemed to deny “rational reasoning” and was more “characteristic of mystics or psychics.” What's more, Beyler determined that the investigation violated, as he put it to me, “not only the standards of today but even of the time period.”
... Just before Willingham received the lethal injection, he was asked if he had any last words. He said, “The only statement I want to make is that I am an innocent man convicted of a crime I did not commit. I have been persecuted for twelve years for something I did not do. From God's dust I came and to dust I will return, so the Earth shall become my throne.”
The researchers focused on a single molecule of pentacene, which is commonly used in solar cells. The rectangular-shaped organic molecule is made up of 22 carbon atoms and 14 hydrogen atoms. In the image [on the right] the hexagonal shapes of the five carbon rings are clear and even the positions of the hydrogen atoms around the carbon rings can be seen.
To give some perspective, the space between the carbon rings is only 0.14 nanometers across, which is roughly one million times smaller than the diameter of a grain of sand.
For solar shoppers these days, the price is right. Panel prices have fallen about 40 percent since the middle of last year, driven down partly by an increase in the supply of a crucial ingredient for panels, according to analysts at the investment bank Piper Jaffray.
The price drops — coupled with recently expanded federal incentives — could shrink the time it takes solar panels to pay for themselves to 16 years, from 22 years, in places with high electricity costs, according to Glenn Harris, chief executive of SunCentric, a solar consulting group. That calculation does not include state rebates, which can sometimes improve the economics considerably.
So, rather than have a machinist try to copy the heater and then build it, we decided to redesign the original using our NextEngine 3D scanner and Dimension 3D printer. These incredible devices allow you to make the form you need to create almost any part. The scanner can measure about 50,000 points per second at a density of 160,000 dots per inch (dpi) to create a highly detailed digital model. The 3D printer makes an exact copy of a part in plastic, which we then send out to create a mold. Some machines can even make a replacement part in cobalt-chrome with the direct laser sintering process. Just feed a plastic wire—for a steel part you use metal wire—into the appropriate laser cutter.
Inside the printer, the print head goes back and forth, back and forth, putting on layer after layer of plastic to form a 3D part. If there are any irregularities in the originals, you can remove them using software. Once the model is finished, any excess support material between moving parts is dissolved in a water-based solution. Complexity doesn’t matter, but the size of the object does determine the length of the process. Making a little part might take 5 hours. The White’s feedwater heater required 33 hours.
Studies show that talking on a cellphone while driving is as risky as driving with a .08 blood alcohol level -- generally the standard for drunken driving -- and that the risk of driving while texting is at least twice that dangerous. Research also shows that many people are aware that the behavior is risky, but they assume others are the problem.
... Prosecutors and judges in other states already have the latitude to use more general reckless-driving laws to penalize multitasking drivers who cause injury and death. In California, for instance, where texting while driving is banned but the only deterrent is a $20 fine, a driver in April received a six-year prison sentence for gross vehicular manslaughter when, speeding and texting, she slammed into a line of cars waiting at a construction zone, killing another driver.
It’s a fascinating little clip which pays homage to a woman who, even beyond her amazing circumstances, was a radical socialist, suffragist, and supporter of birth control, who was friends with the likes of Mark Twain and who worked tirelessly to champion the rights of both the downtrodden and the physically disabled.
Ultracapacitors offer a way to extend the life of a hybrid vehicle's power source, reducing the need to oversize its battery packs. Unlike batteries, ultracapacitors don't rely on chemical reactions to store energy, and they don't degrade significantly over the life of a car, even when they are charged and discharged in very intense bursts that can damage batteries. The drawback is that they store much less energy than batteries--typically, an order of magnitude less. If, however, ultracapacitors were paired with batteries, they could protect batteries from intense bursts of power, Bohn says, such as those needed for acceleration, thereby extending the life of the batteries. Ultracapacitors could also ensure that the car can accelerate just as well at the end of its life as at the beginning.
We took to the hills of Wales armed to the teeth with sheep, LEDs and a camera, to create a huge amazing LED display. Of sorts. For more info search for Samsung LED TV.
"Iraq has advanced the cause of full integration for women in the Army by leaps and bounds," said Peter R. Mansoor, a retired Army colonel who served as executive officer to Gen. David H. Petraeus while he was the top American commander in Iraq. "They have earned the confidence and respect of male colleagues."
In Monterey Bay there's a jumble of rock
Stacked up like a castle across from the dock.
The king of this castle, on old crab called Kermit,
Lived all by himself in a cave like a hermit.
There was never a crab who was one half as selfish
Or one tenth as mean as this crusty old shellfish.
Most natural climate change has taken place over thousands or even millions of years. But an episode of abrupt climate change occurred over centuries—possibly decades—during Earth’s most recent period of natural global warming, called the Bolling-Allerod warming. Approximately 19,000 years ago, ice sheets started melting in North America and Eurasia. By 17,000 years ago, the melting glaciers had dumped so much freshwater into the North Atlantic that it stopped the overturning ocean circulation, which is driven by density gradients caused by influxes of freshwater and surface heat. This occurrence led to a cooling in Greenland called the Heinrich event 1. The freshwater flux continued on and off until about 14,500 years ago, when it virtually stopped. Greenland’s temperature then rose by 27 degrees Fahrenheit (15 degrees Celsius) in several centuries, and the sea level rose about 16 feet (5 meters). The cause of this dramatic Bolling-Allerod warming has remained a mystery and source of intense debate.
That car, the Nissan Leaf shown here, is the reason we find ourselves in the company's brand-new Yokohama headquarters today. Designed as a four-to-five seat, front-drive C-segment hatchback, Nissan says the Leaf is not just for use as a specialty urban runabout, but rather, it was designed as an everyday vehicle – a "real car" whose 160-kilometer+ (100 mile) range meets the needs of 70% of the world's motorists. In the case of U.S. consumers, Nissan says that fully 80% of drivers travel less than 100km per day (62 miles), making the Leaf a solid fit for America's motoring majority, even taking into account power-sapping external factors like hilly terrain, accessory draw, and extreme temperatures.
Another persistent source of Arab human insecurity is high unemployment. “For nearly two and half decades after 1980, the region witnessed hardly any economic growth,” the report found. Despite the presence of oil money (or maybe because of it), there is a distinct lack of investment in scientific research, development, knowledge industries and innovation. Instead, government jobs and contracts dominate. Average unemployment in the Arab region in 2005 was 14.4 percent, compared with 6.3 percent for the rest of the world. A lot of this is because of a third source of human insecurity: autocratic and unrepresentative Arab governments, whose weaknesses “often combine to turn the state into a threat to human security, instead of its chief support.”
However...
Fayyad, a former finance minister who became prime minister after Hamas seized power in Gaza in June 2007, is unlike any Arab leader today. He is an ardent Palestinian nationalist, but his whole strategy is to say: the more we build our state with quality institutions — finance, police, social services — the sooner we will secure our right to independence. I see this as a challenge to “Arafatism,” which focused on Palestinian rights first, state institutions later, if ever, and produced neither.
Nissan, Japan's third largest carmaker, has been slower than rivals Toyota and Honda to embrace hybrids, which run on petrol and electric engines, and is instead pinning its hopes on solely battery-powered cars.
Electric cars have struggled to become mainstream because of limited battery life and high costs. But Mr Ghosn insisted that the Leaf would not be a niche-market vehicle. "We need to invest a lot of money to build the car plants and the battery plants at a moment where all the auto companies are saving investments," he said.
First, the hospital is Coast Provincial General Hospital (sometimes said to be Coast Province General Hospital), not Coast General Hospital. Second, Kenya was a Dominion the date this certificate was allegedly issued and would not become a republic for 8 months. Third, Mombasa belonged to Zanzibar when Obama was born, not Kenya. Fourth, Obama's father's village would be nearer to Nairobi, not Mombasa.
Fifth, the number 47O44-- 47 is Obama's age when he became president, followed by the letter O (not a zero) followed by 44--he is the 44th president. Sixth, EF Lavender is a laundry detergent. Seventh, would a nation with a large number of Muslims actually say "Christian name" (as opposed to name) on the birth certificate?
80% of the end-user response time is spent on the front-end. Most of this time is tied up in downloading all the components in the page: images, stylesheets, scripts, Flash, etc. Reducing the number of components in turn reduces the number of HTTP requests required to render the page. This is the key to faster pages.
One way to reduce the number of components in the page is to simplify the page's design. But is there a way to build pages with richer content while also achieving fast response times? Here are some techniques for reducing the number of HTTP requests, while still supporting rich page designs.
In its first-ever assessment of the world's major oil fields, the IEA concluded that the global energy system was at a crossroads and that consumption of oil was "patently unsustainable", with expected demand far outstripping supply. Oil production has already peaked in non-Opec countries and the era of cheap oil has come to an end, it warned.
In most fields, oil production has now peaked, which means that other sources of supply have to be found to meet existing demand. Even if demand remained steady, the world would have to find the equivalent of four Saudi Arabias to maintain production, and six Saudi Arabias if it is to keep up with the expected increase in demand between now and 2030, Dr Birol said.
The interior is all business, and not in the business class kind of way. The cockpit is spartan, with little in the way of comfort or superfluous design. The the business of flight test and there isn’t much for pilot comfort or fancy design. The flight to Oshkosh took 5 hours and 20 minutes cruising at 350 knots (about 400 mph) true airspeed. Interestingly, when WhiteKnightTwo is flying light as it was for the trip to AirVenture, it can maintain its cruising speed with the engines at idle.
WhiteKnightTwo will carry SpaceShipTwo to an altitude of about 50,000 feet. At that point, it will release SpaceShipTwo, which will then blast off into space. The two craft have identical fuseage, which means allows WhiteKnightTwo to be used as a trainer for future astronauts. The airplane is designed to carry 27,000 pounds at the center of its wing, which makes it strong enough to endure the rigors of simulating zero gravity and the intense g forces experienced during re-entry, Rutan said.
NOAA is rushing to study the data in an effort to understand what happened. Szabados’ office is already putting the finishing touches on a report that will be released next month on the wind and current patterns that appear to be correlated with the tidal surge.
Szabados said that two main factors appear to have contributed to the extra high tides. First, there were steady winds out of the northeast throughout this anomaly. Second, the ocean current running from Florida up along the coast weakened. While the associations between these phenomena and the tides are provocactive, it’s too early to tell how fully they explain this unexpected tidal event.
The Aluminum Test Chamber is a vacuum-tight aluminum plate vessel that is 100 ft. in diameter and 122 ft. high. Designed for an external pressure of 2.5 psig and internal pressure of 5.0 psig, the chamber is constructed of Type 5083 aluminum which is a clad on the interior surface with a 1/8-in. thick type 3003 aluminum for corrosion resistance. This material was selected because of its low neutron absorption cross-section. The floor plate and vertical shell are 1-in. (total) thick, while the dome shell is 1 3/8 in. Welded circumferentially to the exterior surface is aluminum structural T-section members that are 3-ft. deep and 2 ft. wide. The doors of the test chamber are 50 X 50 ft. in size and have double door seals to prevent leakage. The chamber floor was designed for a load of 300 tons.
The term "birthers" seems to have come from the 9/11 conspiracy theorists, who were called "truthers". Here's the Birthers page on Wikipedia. Pretty scary stuff. What is amusing is that it is a poison pill for the Right. They can't disagree with their vocal base but they can't agree because it will marginalize them.
Doctors in the United States are usually paid fees for each service they provide. The more procedures and tests they order, the more money they pocket. There is widespread agreement among health policy analysts that many of these procedures are unnecessary, raising costs in ways that often do nothing to improve patient health.
By contrast, Bassett — like the Cleveland Clinic and a small number of other health systems in this country — pays salaries to all of its doctors. No matter how many tests or procedures are performed, they take home the same amount of money. Medical costs at Bassett are lower than those at 90 percent of the hospitals in New York, while the quality of care ranks among the top 10 percent in the nation, surveys show.
So last year Mr. Hogan [from BearVault] introduced the 450, a two-pound cylinder costing about $60, and a larger version, the 500, each with a second tab. On them, a camper must press in one tab, turn the lid partway, then press the second tab to remove the lid. “We thought, ‘O.K., well, one bump didn’t work so maybe two bumps will thwart her,’ ” he said. But Yellow-Yellow figured that lid out, too.
Last month, her achievements were noted in an article in Adirondack Explorer. And she now appears to have apprentices; campers have reported seeing other bears getting into their BearVaults.
The wind generator has been built to:
Transformers: ROTF has mostly gotten pretty hideous reviews, but that's because people don't understand that this isn't a movie, in the conventional sense. It's an assault on the senses, a barrage of crazy imagery. Imagine that you went back in time to the late 1960s and found Terry Gilliam, fresh from doing his weird low-fi collage/animations for Monty Python. You proceeded to inject Gilliam with so many steroids his penis shrank to the size of a hair follicle, and you smushed a dozen tabs of LSD under his tongue. And then you gave him the GDP of a few sub-Saharan countries. Gilliam might have made a movie not unlike this one.
So you have a movie that tries to reassure men that they can actually be masters of their reality — but then turns around and says that actually, reality is not real. There's no such thing as the "real world," and the only thing that's left for men to dominate is a nebulous domain of blurred shapes, which occasionally blurt nonsensical swear-words and slang from ethnic groups that have never existed. If you're drowning in an Olympic swimming pool full of hot chewing gum fondue, do you still care if Megan Fox likes you?
"The big message is treat alcohol like tobacco," not as a substance that is relatively benign except for "those bad alcoholics," Rehm said. "That is not true."... "So we need to rethink alcohol completely as a risk factor. Of course, we will not prohibit alcohol, but we should make it more expensive so it's consumed in smaller quantities and in quantities which are actually not as detrimental for health."
Performance of these new drives is where it gets really exciting. I've not found a definitive performance study but 100x faster was often cited depending on random-access versus large read/write bandwidth access patterns. Since SSDs are silicon, we should be able to better tap into the silicon improvements. We have seen 10x speed increases of hard drives over the past 20 years while CPUs have increased 1000x. Here's a good article from Rich Coulson with Intel's SSD group.
It is obvious to me at least that within 5 years we will no longer have drives with spinning drives in our computers. Price performance will probably have dropped to 3-5x that of spinning hard drives and performance and density will probably have increased as well.
Translating a linear motion (pistons) to be rotary is inherently inefficient which is why coolant and lubrication systems are so critical in modern cars. Ultimately, I suspect, we will be replacing modern engines with electric motors which have 1 moving parts and are far, far less complicated and far, far more efficient.
The basic concept of a (pistonless) rotary engine avoids the reciprocating motion of the piston with its inherent vibration and rotational-speed-related mechanical stress. As of 2006 the Wankel engine is the only successful pistonless rotary engine, but many similar concepts have been proposed and are under various stages of development...
While typically larger than the piston of an engine of corresponding capacity, a rotor may perform many strokes per revolution. The Wankel produces twelve strokes per revolution of the rotor (four strokes per chamber times three chambers) (although the spindle rotates three times faster than the rotor or three times over the twelve strokes), as opposed to two strokes for each crankshaft rotation of a single-cylinder single acting piston engine, or four strokes for a double-acting cylinder such as found in some steam engines. The quasiturbine and MYT engine deliver sixteen strokes for every rotor (and spindle) revolution.
In 2003, after the Clinton administration spent $1.5 billion on a hybrid-electric sedan, the Bush administration touted $1.2 billion for hydrogen technology. Now, with Barack Obama in the White House, the pendulum is swinging back to plug-ins...
As a candidate, Obama touted plug-in electric vehicles as a cornerstone of his energy policy, pressing for 1 million plug-ins on American roads by 2015. The $787 billion stimulus bill approved by Congress last month includes more than $2 billion in new battery research grants, which are vital to the viability of plug-ins, but no new money for hydrogen research.
Hitachi Maxell, along with Nagasaki University, NIAIST, and Fuji Heavy Industries (the parent company of Subaru, makers of the R1e electric car), announced that it has developed a new chemistry for lithium-ion batteries. Part of the change is dropping the expensive cobalt element and using "nano-infused lithium" with manganese (a very Japanese-sounding element! Pictured left.).
The claim: 20 times more power storage [or faster discharge rates], and the ability to mass-produce it inexpensively. Lets hope it's true and that it will get out of the lab quickly. We'd even settle for only 10 times more power storage...
