North Korea's planned rocket test: Why It Matters
SEOUL, South Korea (AP) ? North Korea may have the bomb, but it hasn't perfected ways to put one onto a missile that could strike faraway enemies like the United States.
This is why Pyongyang's announcement that it will launch a satellite on a long-range rocket next month is drawing so much attention: Washington says North Korea uses these launches as cover for testing missile systems for nuclear weapons that could target Alaska and beyond.
Although North Korea isn't on the official agenda of next week's Nuclear Security Summit in the South Korean capital, here's a look at why the launch will be a major point of discussion when President Barack Obama and other world leaders gather in Seoul:
THE HISTORY
North Korea has spent decades trying to perfect a multistage, long-range rocket.
Next month's launch ? set to happen around the April 15 centennial of the birth of founder Kim Il Sung ? would be the fourth of its kind since 1998, when Pyongyang sent a long-range rocket hurtling over Japan.
A 2006 test was considered a failure, but North Korea grabbed attention shortly after with its first nuclear test blast. The U.N. Security Council later banned North Korea from any further nuclear or ballistic missile testing.
North Korea's third launch, in 2009, was a partial success, with two of the three stages pushing the rocket over the Pacific. The third stage failed, and, despite North Korea's claims of success, no satellite was put into orbit, the U.S. North American Aerospace Defense Command said.
That test was condemned by the U.N. Security Council. Pyongyang protested that it was testing satellite technology for peaceful purposes. It subsequently abandoned six-nation nuclear disarmament talks and, weeks later, carried out a second nuclear test.
The next year saw violence blamed on North Korea that killed 50 South Koreans, including an attack on a warship and the North's shelling of a front-line island.
THE TECHNOLOGY
Experts and governments will scrutinize next month's launch of what the North's state media call an Unha-3 rocket, presumably the next version of the Unha-2 rocket used in the 2009 test.
Unha-2 represented a significant advancement over previous rockets, according to an analysis written by missile experts David Wright and Theodore Postol. It was roughly 100 feet (30 meters) long and may have been designed around Soviet missile components, the writers said.
Next month's rocket is set to fire from a new site on the North's west coast, according to GeoEye and Google Earth satellite imagery posted by Tim Brown, an analyst for GlobalSecurity.org. The Tongchang-ri site is about 35 miles (56 kilometers) from the Chinese border city of Dandong, across the Yalu River from North Korea.
Positioned only 45 miles (70 kilometers) from the North's main Yongbyon nuclear complex, it has better roads and facilities, and allows a southerly flight path that keeps the rocket from flying over other countries, according to Wright, technical researcher at the Union of Concerned Scientists.
The new rocket will probably have better boosters and engines ? and might even succeed in putting a satellite into space if it contains one, said Sohn Young-hwan, a South Korean rocket scientist who heads the privately funded Institute of Technology and Management Analysis in Seoul.
North Korea may have loaded the rocket's third stage with more fuel to increase capability, Wright said by email, part of improvements that "would translate to greater range if that technology was used to build a long-range ballistic missile."
North Korea says the launch is meant to contribute to "international trust and cooperation in the field of space scientific researches."
But because ballistic missiles and rockets in satellite launches "share the same bodies, engines, launch sites and other development processes, they are intricately linked," said Mark Fitzpatrick, an analyst at the International Institute for Strategic Studies.
THE HURDLES
So far, Pyongyang can only deliver a nuclear bomb "by boat, by van or by airplane, not by missile," according to scientist Siegfried Hecker of the Center for International Security and Cooperation at Stanford University.
After half a century of persistence, North Korea is thought to have a fairly small nuclear arsenal.
While it has enough plutonium for about four to eight "simple" bombs similar to what the U.S. dropped on Nagasaki in 1945, Hecker estimates, it doesn't yet appear to have the ability to make bombs small enough to mount on a missile.
Miniaturized warheads would require more nuclear tests, and Hecker warns that if North Korea breaks its nuclear test moratorium, "it will almost certainly be a test of a miniaturized design."
THE DIPLOMACY
Governments and experts are worried that a new rocket launch will spur a chain of events that will mirror 2009, resulting in a breakdown of diplomacy, another nuclear test and soaring tensions, threats and bloodshed.
The United States has warned the launch would jeopardize a diplomatic deal settled last month that would ship U.S. food aid to the impoverished North in exchange for a moratorium on missile and nuclear tests, as well as a suspension of nuclear work at Yongbyon.
"This (the launch) is an extremely bad idea that would have consequences," State Department spokeswoman Victoria Nuland said Friday.
U.S. officials will be pushing China to pressure its ally Pyongyang, and U.S. President Barack Obama is expected to raise the issue during a key meeting with Chinese President Hu Jintao on the nuclear summit's sidelines. There could also be meetings among the U.S. and its Asian allies, Japan and South Korea.
An unidentified North Korean Foreign Ministry spokesman said Friday that his country "remains unchanged in its stand to sincerely implement" the nuclear deal, but warned in a statement carried by the official Korean Central News Agency that "any sinister attempt to deprive" the North of its rights will lead to unspecified "countermeasures."
Hecker, however, said a rocket launch "makes a mockery" of the U.S.-North Korea nuclear deal.
"You use the same technology in long-range rockets that you do in long-range missiles," he said. "The only difference is what you put on top."

Anonymous hackers block Mexico pope visit sites
MEXICO CITY (AP) ? The hacker group Anonymous in Mexico crashed at least two of the websites for Pope Benedict XVI's upcoming visit to Mexico on Thursday, claiming the papal visit is a political move to support the conservative National Action party.
Samuel Najera, spokesman for the Mexican Episcopal Conference, said its web page on the papal visit was blocked by "a cyber attack."
"We have been aware of the threat that has been making the rounds on social networks, that was brought to fruition today," Najera said. "This is part of a dynamic these days of a lack of safety and acts of intolerance toward certain groups."
"For the moment, this does damage to the logistics" of the papal visit, Najera said.
The site contained information on the pope's planned activities starting Friday in the north-central state of Guanajuato, which is governed by President Felipe Calderon's National Action Party, or PAN.
The Anonymous IberoAmerica website, which has been a channel of communication for such hacker "ops" in the past, said the site crashes were the result of Anonymous operations with names such "Pharisee" and "freeloader."
Anonymous Mexico said in a video posted on social media sites that the pope's visit will cost Mexicans money that could be better spent on the poor, and is meant to support the PAN in the July 1 presidential election. PAN candidate Josefina Vazquez Mota is trailing front-runner Enrique Pena Nieto of the Institutional Revolutionary Party by at least 10 percentage points in most polls on the race.
The official campaign season starts at the end of this month.
The pope's "visit comes precisely at the start of the electoral campaigns," said the faceless Anonymous figure in the video. "The PAN will take this as a political weapon to win the votes of millions of Catholics in Mexico."
Guanajuato is 93.8 percent Roman Catholic, the highest of any state in Mexico.
When asked about the timing of the pope's visit, Calderon's office released a March 11 press release noting that Calderon invited the pope in 2007.
Some people have also questioned the pope's decision not to come to liberal Mexico City, where legislators have legalized abortion and gay marriage in the federal district. The Vatican has said the pope cannot be at high altitudes. Mexico City is about 7,300 feet (2,225 meters) above sea level.
Another website with information on where to stay in Guanajuato and how to attend papal events was also crashed. That site was registered to Juan Carlos Mata Ruiz and a group called NIC Mexico.
The website of the Guanajuato state government was also out of service Thursday, the state press office acknowledged, but it would not say whether that was a result of hacking or a cyber attack.

Opponents of 'Stand Your Ground' Predicted Racially Motivated Killings (Little green footballs)
Robot barber shaves head for charity
3 hrs.
Bad hair days for Tim (the guy in the video below), for the moment, are a thing of the past. A robot shaved his head. Now he has little hair to speak of (or a really bad haircut).
The robot barber is a Multi-Arm Unmanned Ground Vehicle from Intelligent Automation. Its three arms, three cameras, and 29 degrees of freedom give "remote operators the ability to perform complex manipulation tasks with relative ease," according to the company.
That means the guy controlling the robot is able to shave Tim's head without knocking off his nifty safety goggles and gouging an eyeball with the clippers.?
If we decide that getting buzz cuts from robots is one automation task too many, the robot will likely find plenty of other work doing things like inspecting suspicious packages, wielding tools, breaking down doors, tying knots and disposing of IEDs, Intelligent Automation notes.?
As for Tim, he wants you to know that he bravely sat in the robot's barber seat to raise funds for the St. Baldrick's Foundation, which searches for cures to childhood cancers. You can also become a shavee with an old-fashioned barber.

Creating Stable Foundations and Structures: Concrete Suppliers for ...
Concrete is a staple in everyday life. It can be found in homes, driveways, walkways, and patios. Concrete is the quintessential construction material for residential, industrial, and commercial structures, and is widely incorporated into foundations, roads, bridges, and even reservoirs.
Concrete is made from a combination of coarse aggregate (gravel), fine aggregate (sand), cement, air, and water. Moreover, concrete is reinforced using steel rods to improve its tensile strength. Concrete is considered a sustainable building material because of its versatile characteristics. It is durable and long-lasting, as well as easy to construct and deconstruct. The manufacture of concrete also utilizes the byproducts of other industries such as power plants, steel mills, and other manufacturing facilities.
Concrete is highly durable as it does not rust, rot, or burn. Structures that have concrete walls, foundations, and floors are also highly energy-efficient. Concrete has inherent thermal mass properties that absorb and retain heat. Both heating and cooling bills may be lowered due to concrete's intrinsic thermal mass.
Concrete also minimizes the unwanted effects that create urban heat islands. For example, light-colored concrete pavements and roofs absorb less heat and reflect more solar radiation than dark-colored materials like asphalt. Additionally, some types of concrete like pervious concrete allow natural water infiltration into the soil. Despite its paved surface, pervious concrete strikes a balance in the natural ecosystem by decreasing the possibility of erosion and flash floods. Moreover, concrete is a minimal waste material. Concrete can be produced in accurate quantities suitable for each project, and can be easily recycled for future use.
Contractors that supply Atlanta concrete can create slopes, walkways, paths, driveways, and patios for your home. Slopes present few challenges for these professionals as they can calculate all inclines accurately. In addition, they can create proper drainage systems to ensure that all surface runoffs from these slopes are adequately drained. Steeper slopes in backyards may also be altered with concrete stairs, thus reducing possible danger zones.
The concrete Atlanta contractors provide can also be used to beautify and strengthen walkways and paths. These contractors can easily work with curvatures and utilize stylish accents that reflect your taste. Homeowners can choose from various finishes such as flagstone, cobblestone, brick, exposed aggregate, and many other natural accents which provide aesthetic benefits.
The concrete repair Atlanta residents need can effectively weatherproof walking surfaces. While severe winter temperatures can cause concrete to crack, this can be prevented with the use of insulated heating blankets.
