China joins supercomputer elite

China has become one of a handful of nations to own one of the top five supercomputers in the world.
China:  Its Tianhe-1 computer, housed at the National Super Computer Center in Tianjin was ranked fifth on the biannual Top 500 supercomputer list.
The machine packs more than 70,000 chips and can compute 563 trillion calculations per second (teraflops).
It is used for petroleum exploration and engineering tasks such as simulating aircraft designs.
However, the fastest machine is the US-owned Jaguar supercomputer, which now boasts a speed of 1.759 petaflops.
One petaflop is the equivalent of 1,000 trillion calculations per second.
The Cray computer has more than 220,000 chips and is owned by the Oak Ridge National Laboratory in Tennessee. It is used to conduct research in climate science, materials science and nuclear energy amongst other areas.
It has taken the top slot from another US machine, nicknamed Roadrunner.
The IBM computer is owned by the Department of Energy's Los Alamos National Laboratory in New Mexico and was the first machine to push through the petaflop barrier.
It is currently able to run at 1.042 petaflops and uses the powerful "cell" chip designed for the PlayStation 3.
It is used to monitor the US nuclear stockpile, as well as conduct research into astronomy, genomics and climate change.
The Top 500 list is dominated by machines in the US, which is home to 277 of ranked systems. It has eight of the top 10 machines.
Europe has 153 systems on the list, including the world's fourth most powerful machine. The IBM BlueGene/P supercomputer at the Forschungszentrum Juelich (FZJ) in Germany is the fastest machine outside the US and is able to run at more than 800 teraflops.
The UK has the largest number of European machines on the list, with 44 systems.

Algerians attack Egyptian firms after football loss

Twenty Algerians injured in Cairo clashes before playoffs
ALGIERS:  Thousands of Algerians held a spontaneous rally Sunday in the capital Algiers in support of their national football team, which degenerated into attacks on Egyptian businesses.
The rally in central Algiers began with fans chanting "One, two, three, Go Algeria!" as they thronged Air Algeria's city-center offices trying to get tickets to travel to Sudan for the second leg World Cup football qualifying match against Egypt in Khartoum on Wednesday.
But it later descended into violence when fans broke through the metal shutters to smash the window and ransack the offices of EgyptAir, an AFP journalist said.

The offices of mobile telephone company Djeezy, part of the Egyptian telecommunications group Orascom, was also ransacked, the website of al-Watan daily reported.
The company also said one of its employees was assaulted at Algiers airport.
Egyptian Prime Minister Ahmed Nazif called his Algerian counterpart Ahmed Owehi on Sunday to appeal for the Algerian government to protect Egyptians in the country, Egypt's official news agency MENA reported.
Egyptian Foreign Ministry spokesman Hussam Zaki said that the Egyptian-Algerian ties are quite strong and would never be affected by any kind of riots launched by fans in both countries.
Zaki denied all the rumors that circulated about the death of Algerian football fans in clashes in Cairo after Saturday's match. "We are now contacting the Algerian security authorities to guarantee the security and safety of all the Egyptians in Algeria," he said.
The Algerian Ambassador to Egypt Abdul Qader Haggar, meanwhile, said that the Algerian security authorities are trying their best to provide all the needed security to the Egyptian businesses operating in Algeria. He denied all the allegations about the death of Algerian fans in Cairo clashes.
Twenty Algerians were injured in clashes in and around Cairo after Saturday's first round match, according to Egyptian police, which Egypt won 2-0 to keep alive its hopes to travel to South Africa next year.

Arabic Web domain opens

Egypt:  Egyptian communications minister Tarek Kamet yesterday announced the introduction of the first Arabic domain, meant to ease Internet access to millions of Arabic speakers around the world.
Registration was to begin for the .misr country code top-level domain, Kamey told the fourth meeting of the Internet Governance Forum.
The announcement follows a decision by the United States-based Internet Corporation for Assigned Names and Numbers to end the exclusive use of Latin characters for website addresses, allowing Internet users to write an entire website address in Chinese, Arabic, Russian and several other scripts.

Barack Obama meets Shanghai students in China


Shanghai:  US president tackles internet censorship and the US stance on arms sales to Taiwan in meeting broadcast on Chinese television.
The US believes that freedom of expression and political participation are universal values, Barack Obama told an audience of young Shanghai students today, in a townhall-style meeting streamed live on the White House website, broadcast on a local Shanghai television station and carried as text on a major Chinese portal.

The president tackled issues ranging from internet censorship and the US stance on arms sale to Taiwan to his Nobel Peace Prize, in his question-and-answer session with around 300 students – his sole meeting with the Chinese public during his three-day visit to the country.
But some expressed disappointment at the soft tone of many questions and said he should have addressed human rights violations in China more directly.
In brief opening remarks Obama repeated earlier assurances that America welcomed China's rise adding: "Because of our co-operation, the US and China are more prosperous and more secure."
But he went on to highlight differences between the two countries, telling his audience: "We do not seek to impose any system of government on any other nation.
"But we also don't believe that the principles that we stand for are unique to our nation."
"These freedoms of expression, and worship, of access to information and political participation – we believe they are universal rights. They should be available to all people, including ethnic and religious minorities, whether they are in the United States, China or any nation."
Asked about China's great internet firewall Obama described himself as "a big supporter of non-censorship" and said criticism enabled by freedom of expression in the US made him a better president.
The president, who arrived in Shanghai late last night to begin the Chinese leg of his four-nation tour, answered questions from internet users and called at random on questioners in the audience – handpicked by officials at universities in the area. Participants in such events are carefully briefed in advance on what they may ask.
China-watchers in the US have long encouraged their government to reach out to the Chinese public, as well as the country's leaders. But the lengthy negotiations required to arrange today's town hall meetings – and the compromises required – are testament to the difficulties of doing so.
At one stage US officials considered ditching the event because of disagreements over the number of attendees – they initially wanted 1,000 present – and whether it would be broadcast live or not.
Campaigners have pushed hard for the president to speak out publicly on human rights issues. Aides have already indicated that he will raise them in his meetings with Chinese leaders.
But Nicholas Bequelin, Asia researcher at Human Rights Watch, said Obama had missed an opportunity, framing such issues as a question of political culture rather than international legal norms.
"What's important is to put a degree of pressure on the Chinese government for its repressive practices," he said.
"You cannot do that without a degree of straight talk. That's not what happened at this meeting … What was needed was to include things relevant to what is happening in the country – as he did in Cairo, for example."
For the most part, the president focused on a message of collaboration and mutual respect. Many of the most sensitive issues mentioned in the thousands of questions posted ahead of the event – such as Tibet – did not emerge.
"There are very few global challenges that can be solved unless the US and China agree," he told a questioner, citing the need to make progress on climate change.
"Other countries around the world will be waiting for us … If they say 'The US and China are not serious about this', they will not be serious either.
That's the burden of leadership that both countries now carry."
Obama's acknowledgement yesterday that time had run out to secure a legally binding deal at Copenhagen and backed plans to postpone a formal agreement until next year at earliest. But aides hope that the world's two largest emitters can move closer on the way forward.
Obama is now on his way to Beijing for two days of talks with Hu and premier Wen Jiabao, which will also address North Korea and Iran's nuclear programmes and the future of Afghanistan and Pakistan. He will also visit the Forbidden City and Great Wall.
Mo Shaoping, one of China's best-known human rights lawyers, told the Financial Times that people "from the American side" had contacted him to see whether he would meet Obama and that he was subsequently questioned about the event by public security officers. The US embassy said it had no knowledge of such a meeting.

Obama Addresses Town Hall Meeting in Shanghai

China: U.S. President Barack Obama met with local political leaders in Shanghai, China Monday and held a town hall meeting with Chinese college students.

At the town hall meeting, Mr. Obama answered questions from the audience and submitted by the Chinese public on various Web sites, including Xinhuanet, Sohu and the U.S. Embassy in Beijing.
The Chinese government carefully controlled media coverage of the event, allowing it to be broadcast on local television but not nationally.
In opening remarks, Mr. Obama announced that the U.S. would expand the number of American students studying in China to 100,000.
