Technology Video Report: 15,000 Websites That Spread Terror and Hate

15,000 Websites That Spread Terror and Hate

Hate groups and terrorists are increasingly using the Internet to spread their beliefs. The Simon Wiesenthal Center based in California says the problem is getting worse. The center has released its latest "Digital Terror and Hate" report. Rick Eaton is a researcher with the group. He says the Internet offers a lot of information not only about things like making explosives, but also about kidnapping and guerrilla warfare. And many times, he says, this information is connected with political philosophy on not only how to do it, but where you should do it and what targets you should attack. The new report identified about fifteen thousand websites considered problematic. They included news groups, social network pages, YouTube videos and games that could incite hatred. Officials say there was only one such website when the center first launched the project in nineteen ninety-five. Rick Eaton says al-Qaida was one of the first terrorist groups to use digital technology. He says the group's online presence continues to grow. The Simon Wiesenthal Center is a Jewish human rights organization. This is its fourteenth year reporting on Internet terror and hate. Rabbi Abraham Cooper is associate dean of the center. He says hate websites increasingly target religious minorities. In his words: "Whether it's a hate crime in the United States or if you're looking at the targeting of Christians from Nigeria, the Coptic Christians in Egypt, what's happened in Iraq, right through to Afghanistan and Pakistan, you have the targeting of millions of people." Rabbi Cooper says we must all take part in solving the problem of Internet terror and hate. He says people need to recognize when websites cross the line from free speech to targeting groups for discrimination and violence. He also says religious and ethnic leaders must work together to condemn all forms of hatred.In his words, "We have to stand up for our own rights and our own communities." He is especially concerned about websites that call for individual acts of violence by people without ties to terrorist organizations. He says such websites are even more worrying because they are harder for law enforcement officials to identify. The new "Digital Terror and Hate" report is the first to be offered to law enforcement officials through an online app that provides up-to-date listings.

Technology: What is Satellite? How Satellites Work?

Technology: What is Satellite? How Satellites Work?

In the context of spaceflight, a satellite is an object which has been placed into orbit by human endeavour. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon.

 

A full-size model of the Earth observation satellite ERS 2

The world's first artificial satellite, the Sputnik 1, was launched by the Soviet Union in 1957. Since then, thousands of satellites have been launched into orbit around the Earth. Some satellites, notably space stations, have been launched in parts and assembled in orbit. Artificial satellites originate from more than 50 countries and have used the satellite launching capabilities of ten nations. A few hundred satellites are currently operational, whereas thousands of unused satellites and satellite fragments orbit the Earth as space debris. A few space probes have been placed into orbit around other bodies and become artificial satellites to the Moon, Mercury, Venus, Mars, Jupiter, Saturn, and the Sun.

Satellites are used for a large number of purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and research satellites. Space stations and human spacecraft in orbit are also satellites. Satellite orbits vary greatly, depending on the purpose of the satellite, and are classified in a number of ways. Well-known (overlapping) classes include low Earth orbit, polar orbit, and geostationary orbit.

Satellites are usually semi-independent computer-controlled systems. Satellite subsystems attend many tasks, such as power generation, thermal control, telemetry, attitude control and orbit control.

Types of Satellite

- Anti-Satellite weapons/"Killer Satellites" are satellites that are designed to destroy enemy warheads, satellites, and other space assets.
- Astronomical satellites are satellites used for observation of distant planets, galaxies, and other outer space objects.
- Biosatellites are satellites designed to carry living organisms, generally for scientific experimentation.
- Communications satellites are satellites stationed in space for the purpose of telecommunications. Modern communications satellites typically use geosynchronous orbits, Molniya orbits or Low Earth orbits.
- Miniaturized satellites are satellites of unusually low masses and small sizes.[13] New classifications are used to categorize these satellites: minisatellite (500–100 kg), microsatellite (below 100 kg), nanosatellite (below 10 kg).
- Navigational satellites are satellites which use radio time signals transmitted to enable mobile receivers on the ground to determine their exact location. The relatively clear line of sight between the satellites and receivers on the ground, combined with ever-improving electronics, allows satellite navigation systems to measure location to accuracies on the order of a few meters in real time.
- Reconnaissance satellites are Earth observation satellite or communications satellite deployed for military or intelligence applications. Very little is known about the full power of these satellites, as governments who operate them usually keep information pertaining to their reconnaissance satellites classified.
- Earth observation satellites are satellites intended for non-military uses such as environmental monitoring, meteorology, map making etc. (See especially Earth Observing System.)
- Tether satellites are satellites which are connected to another satellite by a thin cable called a tether.
- Weather satellites are primarily used to monitor Earth's weather and climate.
- Recovery satellites are satellites that provides a recovery of reconnaissance, biological, space-production and other payloads from orbit to Earth.
- Manned spacecraft (spaceships) are large satellites able for put human into (and beyond) an orbit, being on it and recovery back to Earth. Spacecrafts, and orbital parts-spaceplanes of reusable systems also, has a major propulsion or landing facilities, and often uses as transport to and from the orbital stations.
- Space stations are man-made orbital structures that are designed for human beings to live on in outer space. A space station is distinguished from other manned spacecraft by its lack of major propulsion or landing facilities. Space stations are designed for medium-term living in orbit, for periods of weeks, months, or even years.

Technology: What is GPS (Global Positioning System)?

Technology: What is GPS (Global Positioning System)?

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver.

 

GPS in a Car

The GPS program provides critical capabilities to military, civil and commercial users around the world. In addition, GPS is the backbone for modernizing the global air traffic system.

The GPS project was developed in 1973 to overcome the limitations of previous navigation systems, integrating ideas from several predecessors, including a number of classified engineering design studies from the 1960s. GPS was created and realized by the U.S. Department of Defense (DoD) and was originally run with 24 satellites. It became fully operational in 1994.

Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS system and implement the next generation of GPS III satellites and Next Generation Operational Control System (OCX). Announcements from the Vice President and the White House in 1998 initiated these changes. In 2000, U.S. Congress authorized the modernization effort, referred to as GPS III.

In addition to GPS, other systems are in use or under development. The Russian GLObal NAvigation Satellite System (GLONASS) was in use by only the Russian military, until it was made fully available to civilians in 2007. There are also the planned European Union Galileo positioning system, Chinese Compass navigation system, and Indian Regional Navigational Satellite System.

The design of GPS is based partly on similar ground-based radio-navigation systems, such as LORAN and the Decca Navigator developed in the early 1940s, and used during World War II.

Basic concept of GPS:

A GPS receiver calculates its position by precisely timing the signals sent by GPS satellites high above the Earth. Each satellite continually transmits messages that include:

- the time the message was transmitted
- satellite position at time of message transmission

The receiver uses the messages it receives to determine the transit time of each message and computes the distance to each satellite using the speed of light. Each of these distances and satellites' locations define a sphere. The receiver is on the surface of each of these spheres when the distances and the satellites' locations are correct. These distances and satellites' locations are used to compute the location of the receiver using the navigation equations. This location is then displayed, perhaps with a moving map display or latitude and longitude; elevation information may be included. Many GPS units show derived information such as direction and speed, calculated from position changes.

In typical GPS operation, four or more satellites must be visible to obtain an accurate result. Four sphere surfaces typically do not intersect. Because of this we can say with confidence that when we solve the navigation equations to find an intersection, this solution gives us the position of the receiver along with accurate time thereby eliminating the need for a very large, expensive, and power hungry clock. The very accurately computed time is unused in many GPS applications, which use only the location. A few specialized GPS applications do however use the time; these include time transfer, traffic signal timing, and synchronization of cell phone base stations.

Although four satellites are required for normal operation, fewer apply in special cases. If one variable is already known, a receiver can determine its position using only three satellites. For example, a ship or aircraft may have known elevation. Some GPS receivers may use additional clues or assumptions such as reusing the last known altitude, dead reckoning, inertial navigation, or including information from the vehicle computer, to give a (possibly degraded) position when fewer than four satellites are visible.

How GPS works:

The current GPS consists of three major segments. These are the space segment (SS), a control segment (CS), and a user segment (US). The U.S. Air Force develops, maintains, and operates the space and control segments. GPS satellites broadcast signals from space, and each GPS receiver uses these signals to calculate its three-dimensional location (latitude, longitude, and altitude) and the current time.

The space segment is composed of 24 to 32 satellites in medium Earth orbit and also includes the payload adapters to the boosters required to launch them into orbit. The control segment is composed of a master control station, an alternate master control station, and a host of dedicated and shared ground antennas and monitor stations. The user segment is composed of hundreds of thousands of U.S. and allied military users of the secure GPS Precise Positioning Service, and tens of millions of civil, commercial, and scientific users of the Standard Positioning Service.

Technology Video Report: How Technology Has, and Has Not, Changed Since 9-11

How Technology Has, and Has Not, Changed Since 9-11

Much has been done to improve security in the United States since the terrorist attacks of September eleventh, two thousand one. Intelligence sharing and cooperation between federal, state and local government agencies is said to be at an all-time high.

There have also been improvements in airport security. But a new report says the United States is not as safe as should be. It says America "is not yet prepared for a truly catastrophic disaster." The report is from the National Security Preparedness Group at the Bipartisan Policy Center. The group is led by former New Jersey governor Thomas Kean and former congressman Lee Hamilton of Indiana. The two men also led the 9-11 Commission. Congress established the commission to investigate the hijacking attacks and to make proposals for guarding against future attacks. The new report noted that nine of the reforms proposed by the commission have either been carried out ineffectively or completely ignored. For example, the 9-11 Commission found that communication problems were a major issue during the attacks ten years ago. Police, firefighters and medical crews had trouble talking to each other because they were using different radio frequencies. Officials said this lack of communication led to needless loss of life. The commission said the government should identify radio frequencies that would be used only for emergency communications. However, this has yet to be done. Secretary of State Hillary Clinton commented on the report. She said radio frequencies for first responders was an issue she had worked on in the Senate "and is long overdue for completion." On another issue, border security, she said "We have emphasized innovation. For example, we are now using sophisticated new biometric screening tools to improve border security and the visa process." The report praised the deployment of US-Visit, a biometric entry system in the United States. The US-Visit system uses digital fingerprints and photographic images to identify people entering the United States.

The report notes that a similar system for those leaving the country has yet to be established. It says such a system could have helped officials find two of the hijackers involved in the 9-11 attacks.For VOA Special English, I'm Alex Villarreal.

Technology Video: Siri vs. Google Search

Siri vs. Google Search

Siri vs. Google Search (Jelly Bean)

Siri is how Apple persuades consumers to buy the iPhone 4S, and in iOS 6, the voice assistant promises to get a whole lot better. But before the new and improved Siri arrives, Google is unleashing an upgrade to its search that, well, blows Apple's tech right out of the water. Built from the ground up in the new Android Jelly Bean update, the new search engine accepts and answers questions with aplomb. When we first booted it up and gave it a go, it seriously blew us away with how quick it returned results, and the technology's voice is much more fluid than Siri's robotic pipes. We pitted the two against each other to see just how great Google's enhanced search is, and why Apple's new Siri may already be behind before she even arrives.

VOA Technology Reports: Students Compete to Find Tech Solutions for World Problems

Students Compete to Find Tech Solutions for World Problems
Hundreds of students from around the world recently gathered in New York City for the Microsoft Imagine Cup finals. They came to present their ideas for using technology to solve world problems. Microsoft education director Suzi Levine says the nine-year-old program began mainly as a competition to create technology. She says, "When we realized that students really actually want to have a purpose for what they're creating, we introduced the idea of inspiring them with the UN Millennium Development Goals and suggesting that they use those for their muse." New sources for ideas this year included intergovernmental and nongovernmental organizations and nonprofits. They can submit some of the technical challenges that they would like students to consider for their solutions.Microsoft says over three hundred fifty thousand high school and college students registered for this year's competition. Judges chose more than four hundred of them to attend the finals. Ms. Levine says several teams were inspired by current events, including floods last year in Thailand. A team from Chulalongkorn University in Thailand "created a Windows Phone 7 application that allows you to broadcast your location to your social network of friends so that you can be more easily rescued." There were also ideas from Egypt inspired by the revolution that overthrew president Hosni Mubarak in February. Ms. Levine says one idea "was to use Bluetooth as sort of a Twitter equivalent so that if the government shuts down the Internet, you actually can still have a massive social distribution."Students competed in nine categories. For example, in software design the top prize of twenty-five thousand dollars went to Team Hermes from Ireland. The students developed a device for cars to collect information on road conditions, driving behavior and traffic incidents. A team from Taiwan's National Tsing Hua University won first place in the embedded development category. They developed a network of wireless devices to help plot the safest escape routes during a fire. Next year's awards ceremony will take place in Australia. Microsoft has also announced a three million dollar program to help Imagine Cup winners further develop their projects.For VOA Special English, I'm Carolyn Presutti.

Visa Blogging: Personal Interests: Technology: Apple Confronts the Law of Large Numbers

Apple Inc. formerly Apple Computer, Inc. is an American multinational corporation that designs and sells consumer electronics, computer software, and personal computers. The company's best-known hardware products are the Macintosh line of computers, the iPod, the iPhone and the iPad. Its software includes the Mac OS X operating system; the iTunes media browser; the iLife suite of multimedia and creativity software; the iWork suite of productivity software; Aperture, a professional photography package; Final Cut Studio, a suite of professional audio and film-industry software products; Logic Studio, a suite of music production tools; the Safari web browser; and iOS, a mobile operating system.

As of July 2011, Apple has 357 retail stores in ten countries, and an online store. It is the largest publicly traded company in the world by market capitalization, overtopping ExxonMobil by some $60 billion, as well as the largest technology company in the world by revenue and profit, worth more than Google and Microsoft combined. As of September 24, 2011, the company had 60,400 permanent full-time employees and 2,900 temporary full-time employees worldwide; its worldwide annual sales totalled $65 billion, growing to $108 billion in 2011.

Fortune magazine named Apple the most admired company in the United States in 2008, and in the world from 2008 to 2011. However, the company has received widespread criticism for its contractors' labor, and for its environmental and business practices.

Established on April 1, 1976 in Cupertino, California, and incorporated January 3, 1977, the company was named Apple Computer, Inc. for its first 30 years. The word "Computer" was removed from its name on January 9, 2007, as its traditional focus on personal computers shifted towards consumer electronics.

Now, because of large numbers of people using iPhone, iPad or Apple products have been increasing dramatically that makes the company Apple faces the law of large numbers...

Visa Blogging: Personal Interests: Technology: Do You Know Wetware Computer?

Visa Blogging: Personal Interests: Technology: Do You Know Wetware Computer?

For me, I also don't know the kind of wetware computer, I just know a simple kind of laptop, desktop computer only... How about you? Do you know the wetware computer?

If you don't know neither, let continue find out the wetware computer below..

A wetware computer is an organic computer (also known as an artificial organic brain or a neurocomputer) built from living neurons. Professor Bill Ditto, at the Georgia Institute of Technology, is the primary researcher driving the creation of these artificially constructed, but still organic brains. One prototype is constructed from leech neurons, and is capable of performing simple arithmetic operations. The concepts are still being researched and prototyped, but in the near future, it is expected that artificially constructed organic brains, even though they are still considerably simpler in design than animal brains, should be capable of simple pattern recognition tasks such as handwriting recognition.

What is Neuron?

A neuron (also known as a neurone or nerve cell) is an electrically excitable cell that processes and transmits information by electrical and chemical signaling. Chemical signaling occurs via synapses, specialized connections with other cells. Neurons connect to each other to form neural networks. Neurons are the core components of the nervous system, which includes the brain, spinal cord, and peripheral ganglia. A number of specialized types of neurons exist: sensory neurons respond to touch, sound, light and numerous other stimuli affecting cells of the sensory organs that then send signals to the spinal cord and brain. Motor neurons receive signals from the brain and spinal cord, cause muscle contractions, and affect glands. Interneurons connect neurons to other neurons within the same region of the brain or spinal cord.

A typical neuron possesses a cell body (often called the soma), dendrites, and an axon. Dendrites are thin structures that arise from the cell body, often extending for hundreds of micrometres and branching multiple times, giving rise to a complex "dendritic tree". An axon is a special cellular extension that arises from the cell body at a site called the axon hillock and travels for a distance, as far as 1 m in humans or even more in other species. The cell body of a neuron frequently gives rise to multiple dendrites, but never to more than one axon, although the axon may branch hundreds of times before it terminates. At the majority of synapses, signals are sent from the axon of one neuron to a dendrite of another. There are, however, many exceptions to these rules: neurons that lack dendrites, neurons that have no axon, synapses that connect an axon to another axon or a dendrite to another dendrite, etc.

All neurons are electrically excitable, maintaining voltage gradients across their membranes by means of metabolically driven ion pumps, which combine with ion channels embedded in the membrane to generate intracellular-versus-extracellular concentration differences of ions such as sodium, potassium, chloride, and calcium. Changes in the cross-membrane voltage can alter the function of voltage-dependent ion channels. If the voltage changes by a large enough amount, an all-or-none electrochemical pulse called an action potential is generated, which travels rapidly along the cell's axon, and activates synaptic connections with other cells when it arrives.

With the exception of neural stem cells and a few other types of neurons, neurons do not undergo cell division. In most cases, neurons are generated by special types of stem cells. Astrocytes, a type of glial cell, have also been observed to turn into neurons by virtue of the stem cell characteristic pluripotency. In humans, neurogenesis largely ceases during adulthood—only for two brain areas, the hippocampus and olfactory bulb, is there strong evidence for generation of substantial numbers of new neurons.

Do you know the Georgia Institute of Technology?

The Georgia Institute of Technology (commonly called Georgia Tech, Tech, and GT) is a public research university in Atlanta, Georgia, in the United States. It is a part of the University System of Georgia and has satellite campuses in Savannah, Georgia; Metz, France; Athlone, Ireland; Shanghai, China; and Singapore.

The educational institution was founded in 1885 as the Georgia School of Technology as part of Reconstruction plans to build an industrial economy in the post-Civil War Southern United States. Initially, it offered only a degree in mechanical engineering. By 1901, its curriculum had expanded to include electrical, civil, and chemical engineering. In 1948, the school changed its name to reflect its evolution from a trade school to a larger and more capable technical institute and research university.

Today, Georgia Tech is organized into six colleges and contains about 31 departments/units, with a strong emphasis on science and technology. It is well recognized for its degree programs in engineering, computing, management, the sciences, architecture, and liberal arts. Tech is consistently ranked as one of the top 10 public universities in the nation and is a member of the prestigious Association of American Universities.

Georgia Tech's main campus occupies a large part of Midtown Atlanta, bordered by 10th Street to the north and by North Avenue to the south, placing it well in sight of the Atlanta skyline. In 1996, the campus was the site of the athletes' village and a venue for a number of athletic events for the 1996 Summer Olympics. The construction of the Olympic village, along with subsequent gentrification of the surrounding areas greatly enhanced the campus.

Student athletics, both organized and intramural, are an important part of student and alumni life. The school's intercollegiate competitive sports teams, the four-time football national champion Yellow Jackets, and the nationally recognized fight song "Ramblin' Wreck from Georgia Tech", have helped keep Georgia Tech in the national spotlight. Georgia Tech fields eight men's and seven women's teams that compete in the NCAA Division I athletics and the Football Bowl Subdivision. Georgia Tech is a member of the Coastal Division in the Atlantic Coast Conference.

How about the Arithmetic?

Arithmetic or arithmetics (from the Greek word ἀριθμός, arithmos “number”) is the oldest and most elementary branch of mathematics, used by almost everyone, for tasks ranging from simple day-to-day counting to advanced science and business calculations. It involves the study of quantity, especially as the result of operations that combine numbers. In common usage, it refers to the simpler properties when using the traditional operations of addition, subtraction, multiplication and division with smaller values of numbers. Professional mathematicians sometimes use the term (higher) arithmetic when referring to more advanced results related to number theory, but this should not be confused with elementary arithmetic.

The above explanation is just some concept related to Wetware Computer. And now we may know the new technology of wetware computer...

Visa Blogging: Personal Interests: Technology: Cloaking Technology makes Invisibility a Scientific Reality

Do know Cloaking?

A cloaking device is a theoretical or fictional stealth technology that can cause objects, such as spaceships or individuals, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum. Fictional cloaking devices have been used as plot devices in various media for many years.

Developments in scientific research show that real-world cloaking devices can obscure objects from at least one wavelength of EM emissions. Scientists already use artificial materials called metamaterials to bend light around an object.

Visa Blogging: Personal Interests: Technology: iPhone: Complete Comparison Between iPhone 4S and iPhone 4

Visa Blogging: Personal Interests: Technology: iPhone: Complete Comparison Between iPhone 4S and iPhone 4

The iPhone 4 is a touchscreen slate smartphone developed by Apple Inc. It is the fourth generation iPhone, and successor to the iPhone 3GS. It is particularly marketed for video calling (marketed by Apple as FaceTime), consumption of media such as books and periodicals, movies, music, and games, and for general web and e-mail access. It was announced on June 7, 2010, at the WWDC 2010 held at the Moscone Center, San Francisco, and was released on June 24, 2010, in the United States, the United Kingdom, France, Germany and Japan. The iPhone 4 runs Apple's iOS operating system, the same operating system as used on prior iPhones, the iPad, and the iPod Touch. It is primarily controlled by a user's fingertips on the multi-touch display, which is sensitive to fingertip contact. The most noticeable difference between the iPhone 4 and its predecessors is the new design, which incorporates an uninsulated stainless steel frame that acts as the device's antenna. The internal components of the device are situated between two panels of chemically strengthened aluminosilicate glass. It has an Apple A4 processor and 512 MB of eDRAM, twice that of its predecessor and four times that of the original iPhone. Its 3.5-inch (89 mm) LED backlit liquid crystal display with a 960×640 pixel resolution is marketed as the "Retina Display".

The latest operating system release is iOS 5.0.1. In October 2011, the iPhone 4S was announced, which retains the same form factor but includes many upgrades such as the A5 processor, iOS 5, and an improved camera.

The iPhone 4S is a touchscreen slate smartphone developed by Apple Inc. It is the fifth generation of the iPhone, a device that combines a 3.5 inch (89 mm) touchscreen iPod, mobile phone, and internet communicator. It retains the exterior design of its predecessor, the iPhone 4, but is host to a range of improved hardware specifications and software updates compared to the previous model. Integrated software and hardware changes support the introduction of new user interface and functions by Apple. Highlights include a voice recognizing and talking assistant called Siri, personal computer independence, cloud-sourced data (iCloud) and an improved camera system. A selection of the device's functions can be controlled by voice. The iPhone 4S was unveiled at Apple's "Let's Talk iPhone" event on October 4, 2011 in Cupertino, California. Apple started taking pre-orders for the iPhone 4S on October 7, 2011 in seven initial countries (United States, Canada, Australia, United Kingdom, France, Germany, and Japan) with a first delivery date set for October 14, 2011, and available on that same day for direct store sales in those countries. It was released in 22 more European, American and Asian countries, including Ireland, Mexico and Singapore on October 28. It will be available on 100 carriers in 70 countries overall, including AT&T, Verizon, and for the first time, also for Sprint and C Spire[8] customers in the United States. In Japan it will be available for au (a KDDI brand) and Okinawa Cellular, for the first time.

Visa Blogging: Personal Interests: Technology: Samsung Launch 2GHz Dual-Core Smartphones 2012

Visa Blogging: Personal Interests: Technology: Samsung Launch 2GHz Dual-Core Smartphones 2012

Samsung Group is a South Korean multinational conglomerate corporation headquartered in Samsung Town, Seoul, South Korea. It comprises numerous international affiliated businesses, most of them united under the Samsung brand. Notable Samsung Group industrial subsidiaries include Samsung Electronics (the world's largest information technology company measured by 2010 revenues), Samsung Heavy Industries (the world's second-largest shipbuilder measured by 2010 revenues), and Samsung Engineering and Samsung C&T (respectively the world's 35th- and 72nd-largest construction companies). Other notable subsidiaries include Samsung Life Insurance (the world's 14th-largest insurance company), Samsung Securities, Samsung SDS, Samsung Everland (the oldest theme park in South Korea), Cheil Worldwide (the world's 19th-largest advertising agency measured by 2010 revenues) and Shilla Hotel.

Smartphone

A smartphone is a high-end mobile phone built on a mobile computing platform, with more advanced computing ability and connectivity than a contemporary feature phone. The first smartphones were devices that mainly combined the functions of a personal digital assistant (PDA) and a mobile phone or camera phone. Today's models also serve to combine the functions of portable media players, low-end compact digital cameras, pocket video cameras, and GPS navigation units. Modern smartphones typically also include high-resolution touchscreens, web browsers that can access and properly display standard web pages rather than just mobile-optimized sites, and high-speed data access via Wi-Fi and mobile broadband.

The most common mobile operating systems (OS) used by modern smartphones include Google's Android, Apple's iOS, Microsoft's Windows Phone, Nokia's Symbian, RIM's BlackBerry OS, and embedded Linux distributions such as Maemo and MeeGo. Such operating systems can be installed on many different phone models, and typically each device can receive multiple OS software updates over its lifetime.

The distinction between smartphones and feature phones can be vague and there is no official definition for what constitutes the difference between them. One of the most significant differences is that the advanced application programming interfaces (APIs) on smartphones for running third-party applications can allow those applications to have better integration with the phone's OS and hardware than is typical with feature phones. In comparison, feature phones more commonly run on proprietary firmware, with third-party software support through platforms such as Java ME or BREW. An additional complication in distinguishing between smartphones and feature phones is that over time the capabilities of new models of feature phones can increase to exceed those of phones that had been promoted as smartphones in the past.

Samsung Launch 2GHz Dual-Core Smartphones 2012!

Visa Blogging: Personal Interests: VOA Technology Report: Living in a World With Facial Recognition

Visa Blogging: Personal Interests: VOA Technology Report: Living in a World With Facial Recognition

This post I would like to share with you a very interesting technology report from Video of VOA Online English Resources...

Living in a World With Facial Recognition

A new study looks at privacy in a world where computers can increasingly recognize faces in a crowd or online. Alessandro Acquisti at Carnegie Mellon University's Heinz College in Pittsburgh, Pennsylvania, led the study. Professor Acquisti says social networks like Facebook and LinkedIn represent some of the world's largest databases of identities. He sees increasing threats to privacy in facial recognition software and cloud computing -- the ability to store huge amounts of information in data centers. "The convergence of all these technologies -- face recognition, social networks, cloud computing -- and all these advances in ... data mining are creating this world where you can blend together online and offline data. You can start from an anonymous face and end up with sensitive inferences about that person." Recognition systems measure things like the size and position of a nose, the distance between the eyes and the shape of cheekbones. The software compares lots of images to try to identify the person. Facial recognition programs are used in police and security operations. But the software is increasingly popular in other uses, including social media sites.For the study, the Carnegie Mellon team used software from Pittsburg Pattern Recognition, or PittPat. Google bought that company last month. The software can recognize faces in photos and videos. The researchers did three experiments. First, they collected profile photos from a dating website. Its users try to protect their privacy by not listing their real name. But comparing their photos to pictures on Facebook identified one out of ten people.In the second experiment, the Carnegie Mellon researchers asked permission to take pictures of students on campus. They compared these to photos on Facebook. This time they correctly identified one-third of the students. In the third experiment, they tried to see how much they could learn about people just from a photo. They found not only names but birthdates, personal interests and even locations, when people listed them. And Professor Acquisti says "face recognizers" keep improving. In June, Facebook launched a facial recognition system to help users "tag" or list the names of people in photos. Germany became the first country to declare this software a violation of privacy. For VOA Special English, I'm Alex Villarreal.
