An external optical drive is intended for owners of ultra-portable notebook or netbook.
As is known, the market is now many outstanding products of ultra portable notebooks or ultra-thin, or netbooks. This compact ultra-portable computers generally come with an optional optical drive. That is, users who need to buy the drive separately.
Samsung SE-S084D is intended to meet the above requirements. Users only need to connect the USB cable into the device and port on the netbooks, for example, the netbook has been able to directly use the dvd writer.
In the connecting cable, Samsung also provides an additional USB connector that serves as a backup if the USB port on the computer can not supply sufficient amounts of power that causes the drive can not be used or the power shortage during combustion.
The method used to embed a tray loading CD or DVD. To open the tray, users can simply touch or mencolekkan finger on the cover drive. After the disc is inserted, Samsung says, about 190 milliseconds later, the data can be accessed.
If connected to a video device that supports USB, an external optical drive can also be directly used. For example, if you want to see the film through the projector, if your projector supports input via USB, then stay put DVD movies into this drive, connect to a projector, is completed.
When tested, when used to write to DVD-R media, Samsung SE-S084D can write with an average speed of 5.98 x. When writing to DVD-R DL media, he wrote velocity reaches 3.75 x and when writing to CD media, the average write speed of this drive reached 18.87 x.
There is no problem when writing or reading to a media DVD-R or CD-R. Literacy drive is pretty good. However, when writing to DVD-R DL media, it seems Samsung SE-S084D little obstacles. Similarly, when examined with Surface Scan inherent property of Nero 9, the results show there is a part of the offerings that were given the category Bad.
This problem may be solved by the newer firmware later. Fortunately, Samsung's Firmware Live Update feature on this drive. Condition, the computers that use the SE-S084D DVD Writer must be connected to the Internet.

Will Robots Clean Up Future Oil Spills
Cleaning oil spills can be costly business. If eco-friendly robots can take over and clean all the mess it will be good for marine life and humans too. MIT is developing Seaswarm robots that will utilize a special substance to absorb and collect oil from the sea surface. If everything turns out well, these robots can be used commercially in a year. These robots work best collectively. They can detect the oil spills on their own and then convey the message to their robotic group and chalk out a strategy among themselves to clean the mess.Design of a Seaswarm:
Assaf Biderman supervised this project at MIT. He is also the associate director of MIT’s Senseable City Lab. According to him the $20,000 robots will be put on exhibition in Venice, Italy. The Seaswarm robots give the appearance of a conveyor belt of a treadmill. The conveyer belt contains material which the MIT guys call a paper towel for oil spills. It can absorb up to 20 times its weight in oil. This belt floats on the sea surface and connected to an ice cooler. When it turns the belt pushes the robots frontward and absorbs the oil with the aid of a nanomaterial. This nanomaterial is designed to attract oil and repel water. Biderman explains it as a carpet rolling on the surface of the water.
How Seaswarm works:
After soaking up the oil on the sea surface the robot can burn it on the spot or it can leave the oil in a bag which can be collected later. The heater is located on the “ice cooler” part of the body. The oil stored in the bag can be reused. According to Biderman, robots are good team players. They coordinate with one another with the help of GPS location data. They devise a strategy to clean up the mess in an effective way.
Advantages of Seaswarm:
Cost effective: If the Seaswarm robots are being deployed at the oil spill site they prove to be relatively cheap, quick and effective at cleaning up oil spills. Otherwise cleaning oil spills is quite costly as it need big ships and trained crews in large numbers. Biderman is of the opinion that if the Seaswarm robots would have been used at the Deepwater Horizon oil disaster, the robots would have cleaned up the oil in two months. The cost of the whole operation would have amounted to $100 million to $200 million. If we care to look at the statistics about 800 skimming boats were in service to clean up the Deepwater Horizon oil disaster. It would have needed only 5,000 to 10,000 of MIT’s autonomous robots to complete the same task.
Eco Friendly: The Seaswarm robots use clean and green solar energy. They need only 100 watts of power, or about that of a bright light bulb for their operations. You can utilize them on sea for months and they won’t ask for overtime for working incessantly.
Stability: Biderman says, “Because it (conveyor belt) adheres to the surface of the water, it cannot capsize,” he said, “So it can withstand quite severe weather. Imagine this like a leaf that lands on the surface of the water and moves with the waves and the currents and cannot be flipped over.” The robots can work under extreme conditions and rough weather. Biderman said MIT’s oil-sopping robot would be most effective in situations like the recent oil disaster, where oil is spread out.
Damage can be confined to a smaller area: Biderman shares his opinion, “Ideally, when spillage happens, the best thing to do is to contain it right where the spillage occurs. But quite often the oil goes out of containment, and this is where this technology would be most effective.”
Early Detection of Diabetes
Scientists in London, England, found a way to detect the possibility of having diabetes 10 years. "This test works by detect the molecular genetic level in the blood, molecules called microRNA (MIR), which also can detect people at risk of heart attack or problems with blood vessels." Told by Dr. Manuel Mayr, research leader at the University of London King.Diabetes is a disease that can snatch the vision, the kidneys, even the heart. A disease that has killed thousands of people. Nevertheless, many people who just shrugged when asked about the possibility of this disease because their symptoms can indeed invisible.
World Health Organization (WHO) and International Diabetes Federation estimates more than 50 percent of people with undiagnosed type 2 diabetes. They are generally new diabetes discovered during treatment for other diseases. The majority of patients with diabetes come to the doctor had brought a pile of complications.
London scientists this invention can be used as reference precautions for patients who have the possibility of diabetes.
Wrinkles in Face Triggers
Added age skin becomes thinner, dry, and no elastic. This then makes the skin loses the ability to be free from defects. From this early formation of wrinkles, which if left unchecked would disrupt the performance. Besides age, there are four factors that trigger wrinkle face uninvited.1. Cigarette
Experts agree, there is a relationship between cigarette to the accelerated aging process. Not only the cigarette smoke, nicotine is smoked by a reduced blood flow to the skin. When blood flow is reduced, the skin nutrient deficiencies. This then makes the regeneration of skin cells do not go perfectly, which is followed by the appearance of wrinkles, wrinkles in the face. How to overcome that is not to be active or passive smokers.
2. Genetic
In certain people, the emergence of wrinkles faster apparently inherited. So if history is present in your families, most likely the wrinkles will be formed ahead of time. Quite difficult to find a solution for avoiding wrinkles in the face. But you can not keep dry skin by always using a moisturizer.
3. The skin is too white
Maybe you've heard, darker skin will look younger longer. Why, melamine dark-skinned people more numerous and dense, melamine, besides as a pigment the skin, also serve to protect the skin from ultraviolet radiation. How to avoid is either white or black owners, still need a sunscreen cream off an attack to ultraviolet A and B.
4. Sun exposure
Ultraviolet light, particularly ultraviolet A can freely penetrate the skin through collagen. When collagen is damaged, your skin loses its patron. To avoid this do not forget to use sunscreen cream every time outdoors.
IBM Launches z196 processor speed of 5.2 GHz
Up to how fast the computer processor can 'run'? IBM's answer that question by launching a new processor called the z196.Processor that is claimed to be the fastest processor in the world can 'run' with clock speeds up to 5.2 GHz. Imagine how much heat the processor.
Previously, AMD Phenom II X6 has a clock speed of up to 3 GHz. Intel Core 2 Duo E8700 works at a speed of 3.5 GHz. In fact, Tom's Hardware had time to refine the project 5 GHz clock-speed processors, with liquid nitrogen cooling system.
However, this time the processor Z196 does not require liquid nitrogen for cooling assistance. This four-core processors using 45 nanometer processing technology, containing up to 1.4 billion transistors in a cross-sectional area of 512 square mm.
Claimed to be able to handle more than 50 billion instructions per second computing. Processors of this zEnterprise class reportedly has cost the fund more than U.S. $ 1.5 billion.
As quoted from TechIT site, IBM's research department has collaborated with some of his clients during the three years to realize the creation of this proseseor.
However, this processor would certainly not we meet at the Alienware gaming laptops or other consumer laptops, because these processors will only be present on the mainframe computers used by large clients like banks, telco companies, as well as manufacturing industries.
The plan of this processor will begin to be marketed by IBM, commencing 10 September.
Snakebot, Snake Robot That Can Sing
After the mobile robot cockroaches that could make someone ran. Now comes the snake robot that can be wrapped around trees like a real snake.Robot named Snakebot made by Biorobotics Lab at Carnegie Mellon University (CMU), Pittsburgh, United States. Snakebot able to coil around themselves on poles, trees and walking into the pipe vertically.
Snakebot a snaking run even able to shake its tail in the tree, looking around him through the head contains a camera and even more amazing snakebot able to sing the national anthem of the U.S. 'Star-Spangled Banner' that made him get the nickname 'Uncle Sam'.
Snakebot robot apparently has been used in disaster training and are expected to someday be able to search and rescue operation in the field condition which does not allow people to enter it.
Modular robot is built from segments of sensors and actuators that enable it to alter the length and easy to be assembled again.
Researchers at CMU noted that in the experiment to climb trees, new Snakebot can climb on tree trunks with a certain width.
"The investigators worked to design, build and program a robot. But much remains to be repaired so that the robot was able to climb trees higher with various sizes of trees and to facilitate navigation of the branch and cable," said the Carnegie Mellon University.
Arabs consider Blackberry as an spy U.S and Israeli
State Police of the United Arab Emirates (UAE) that has many reasons to press the Blackberry. Not only related to terrorism, the Arabs too suspicious if the Blackberry becomes a spy to U.S. and Israeli governments."The U.S. is the main beneficiary of the lack of control over the Blackberry data. Because they have the right to spy on the country the UAE," said Dubai Police Chief Dhahi Khalfan Tamim, as quoted by Reuters on Saturday (09/04/2010).
According to Tamim, Western countries have accused the Arabs as a restraint of freedom use the Blackberry but on the other hand they are even allowed to access data that exist in the blackberry. Western countries that Tamim was referred to the U.S., Israeli, British and others.
Unfortunately, Tamim did not explain further U.S. goals have an interest to spy on the UAE. Previously, Tamim even been blamed Israel for the death of Palestinian military leader who was in Dubai in January last.
UAE itself has been an ultimatum Blackberry manufacturer, Research in Motion (RIM) for blocking of the service, messenger, email or web browser, on 11 October. The decision will apply as if RIM can not provide access to encrypted data on the Blackberry Arabs who now has 500 thousand users.
Earlier in India, RIM is also getting the same pressure but the blockade was delayed because RIM has promised to provide such access to the Indian government.
Geological Wonders of the World
Save a lot of natural wonders. Every country has a fascinating area. These are some places in the world who entered the category of 'geological wonders' you may already know, or did not you realize.
1. The Wave, United States
Located between Arizona and Utah, USA. This stunning red rock located on the border of Arizona and Utah, USA. The Wave was formed from sand dune 190 million-year-old who was turned into stone.
Formation of a little-known people can only be accessed by walking through a small street about three miles uphill.
2. Antelope Canyon, Arizona, United States
Antelope canyon or Antelope Canyon is a famous gorge located in Page, Coconino County, Arizona, United States.
This canyon areas into the complex Navajo Indian Reservation, the area's largest shelter for Dine Indians from North America, also called Navaho or Navajo.
Antelope Canyon was formed by erosion of Navajo Sand Stone, primarily due to flash floods and later because of sub-aerial processes.
3. Great Blue Hole, Belize
Part of the Lighthouse Reef System, the Great Blue Hole is located approximately 60 miles from the mainland of Belize City. Shaped like a big hole almost perfectly, with a depth of about 125 meters and 300 meters in diameter.
The depth of water makes a very blue color. This is believed to be the world's largest ocean holes and has a big attraction for divers.
4. Crystal Cave of the Giants, Mexico
Found deep in a mine in Chihuahua, Mexico. Known as "the Sistine Chapel of crystals", Mexico's Cueva de los Cristales (Cave of Crystals) contains natural crystals are world famous. These crystals have an average length of 11 meters.
5. Eye of the Sahara, Mauritania
A land in Mauritania, south-western part of the Sahara has a spectacular view. Threaded circle with a diameter of 30 miles - like eyes. Because of this magnitude can be seen from outer space.
Formation was originally suspected as the impact of a meteorite collision but, geologists now believe this is the result of elevation and soil erosion. However, what makes a circular shape, is still mysterious.
6. Blue Lake Cave, Brazil
Mato Grosso do Sul region of Brazil has some beautiful underground lake, there Gruta do Lago Azul, Gruta do Mimoso, and Aquario Natural.
The most famous, Gruta do Lago Azul or Blue Lake Cave - decorated with stalactites and stalagmites and incredibly blue lakes. The beauty of the lake was very impressive.
7. Giants Causeway, Irlandia
Is an area of 40 000 which consists of pieces of the column. Giants Causeway is the result of ancient volcanic eruptions.
Located in the north-east coast of Northern Ireland, mostly hexagonal columns, although there are also some of the terms of the four, five, seven and eight. The highest column is 12 meters, and high profits that hardens on the cliff is 28 meters.
8. Hell Gate, Turkmenistan
There in the Karakum Desert in Turkmenistan. Near the remote village, inhabited by 350 people Derweze, there is a crater 60 meters wide and within 20 meters.
This crater is continually generate fire and burned for 38 years.
By local residents, this smoldering crater known as Crater Gas Darvaza or also better known as the 'Gate of Hell'. These craters can be seen from a distance of several kilometers.
This is not a natural phenomenon, but rather the result of industrial accidents. In 1971, a Soviet drilling rig was incidentally related to an underground cave that holds the gas in massive quantities.
9. Wave Rock, Australia
Rock or stone Wafe waves are natural rock formation located in Western Australia. Shaped like a circular waves.
One wave has a height of about 15 meters long and 110 meters.
