RIM: BlackBerry 10 smartphones won't arrive until end of 2012

Some unfortunate news was revealed for those BlackBerry addicts who've waited patiently for a QNX-based smartphone from RIM. The company's co-CEO, Mike Lazaridis, reports that, due to a critical chipset that's not expected to be available in production quantity until mid-next year, we're unlikely to see a BlackBerry 10 device emerge until late in 2012. We know, ouch. When asked during today's conference call about the delay, the company leaders defended the decision and reiterated that a suitable alternative wouldn't be available that delivers a sufficient balance of processing power and battery longevity. As RIM's fans cope with the latest news, the firm promises that it's continuing to work on delivering a high-quality user experience and industrial design for its upcoming lineup. With the farm riding on this release, we can only hope so.

900MHz frequency seen having its way with Galaxy Nexus bootloader


Youtube link for mobile viewing

The mystery of the Samsung Galaxy Nexus' 900MHz bug continues. Sort of. We've just been sent this video of the Galaxy Nexus volume buttons being affected by a nearby 900MHz signal while the Galaxy Neuxs is in the bootloader. The Galaxy Nexus in question is said to have had the recent update that fixes the 900MHz wonkiness while Android is running, but you can clearly see the strangeness here in the bootloader.

Those of us in the states will have a hard time reproducing this, of course, since we're not exactly crawling in 900MHz EDGE. (Or in the Galaxy Nexus, for that matter.) And while it's an interesting-looking bug, we're not sure how overly concerned we are about this lingering issue. Maybe it'll be fixed with uploaded bootloader code. But if not, maybe just keep your 900MHz phones a inch away from your Galaxy Nexus.

Thanks, Jeremy!

Rare attacks on Afghan Shiites kill 60 (AP)

KABUL, Afghanistan ? A suicide bomber struck a crowd of Shiite worshippers who packed a Kabul mosque Tuesday to mark a holy day, killing at least 56 people, and a second bombing in another city killed four more Shiites. They were the first major sectarian assaults since the fall of the Taliban a decade ago.

A third attack, a motorcycle bomb in the southern city of Kandahar, killed one civilian. But police said it did not target Shiites as they commemorated Ashoura, which marks the seventh century death of the Prophet Muhammad's grandson Imam Hussein.

Religiously motivated attacks on Shiites are rare in Afghanistan although they are common in neighboring Pakistan.

A man who claimed to be from Lashkar-e-Jhangvi, one of Pakistan's most ruthless Sunni militant groups which has carried out attacks against Shiite Muslims, called various media outlets in Pakistan to claim responsibility for the bombing in Kabul, which was reminiscent of the wave of sectarian attacks that shook Iraq during the height of the war there. The validity of the claims could not be determined.

The bomber blew himself up in a crowd of men, women and children gathered outside the Abul Fazl shrine. Mahood Khan, who is in charge of the shrine near the presidential palace, said the explosion occurred just outside a packed courtyard where dozens of worshippers were lined up as they filed in and out of the crowded building.

Some men were beating themselves in mourning, an Ashoura tradition, and food was being distributed.

"It was a very powerful blast," Khan said. "The food was everywhere. It was out of control. Everyone was crying, shouting. It is a disaster."

Bodies of the dead lay on top of one another where they fell. Survivors with blood-smeared faces cried amid the chaos. A few minutes after the blast, bodies could be seen loaded into the trunks of cars while wounded were led away by friends and relatives. Survivors wept in the streets.

Mustafa, a shopkeeper, said he and his mother were delivering food to the worshippers when the blast occurred. Two groups of 150 to 200 people from Kabul had just prayed at the shrine and left.

Another group of more than 100 from Logar province was entering when the explosion occurred. He said the suicide bomber was at the end of the line of worshippers from Logar when he blew himself up near one of the gates to the shrine.

"It was very loud. My ears went deaf and I was blown 3 meters (yards)," said Mustafa, who uses only one name. "There was smoke and red blood on the floor of the shrine. There were people lying everywhere."

The shrine's loudspeaker continued to blast a recitation of the Quran as ambulances carried bodies and wounded away. Women stood outside wailing and holding crying children.

The Public Health Ministry said 56 were killed ? including two women and four children. Sayed Kabir Amiri, who is in charge of Kabul hospitals said more than 160 were wounded. It was the single deadliest attack in the Afghan capital in more than three years.

Four other Shiites were killed in the northern city of Mazar-i-Sharif. A bomb strapped to a bicycle exploded as a convoy of Afghan Shiites was driving down the road, shouting slogans for Ashoura. Health Ministry spokesman Sakhi Kargar gave the death toll and said 21 people were wounded.

The Interior Ministry said police defused another bomb planted in Mazar-i-Sharif near the one that blew up.

The Ministry of Interior blamed the Taliban and "terrorists" for the attacks.

The Taliban strongly condemned the attacks and said they deeply regretted that innocent Afghans were killed and wounded.

Afghan President Hamid Karzai, speaking at a news conference after meeting German Chancellor Angela Merkel in Berlin, said the attack was unprecedented in scope. He said it was "the first time that on such an important religious day in Afghanistan terrorism of that horrible nature is taking place." Karzai cut short his visit to Europe to return to Kabul. He canceled his trip to Britain where he was to meet Prime Minister David Cameron, Prince Charles and deliver a speech to the London School of Economics, British officials said.

Mohammad Bakir Shaikzada, the top Shiite cleric in Kabul, said he could not remember a similar attack having taken place on such a scale.

"This is a crime against Muslims during the holy day of Ashoura. We Muslims will never forget these attacks. It is the enemy of the Muslims who are carrying them out," he said, declining to place blame.

Shiites make up about 20 percent of Afghanistan's 30 million people, most of them ethnic Hazaras. Although thousands of Hazaras were massacred by the Taliban during fighting in the 1990s, Afghan insurgents ? nearly all of them Sunnis ? in recent years have focused their attacks primarily on U.S.-led NATO troops and Afghan security forces.

It was unclear whether Tuesday's attacks mark a change in Afghan Taliban strategy or were carried out by al-Qaida or another group based in Pakistan, where Sunni attacks on Shiites are common. Hard-line Sunnis consider Shiites nonbelievers because their customs and traditions differ from the majority sect.

In neighboring Pakistan, Sunni militants with links to al-Qaida and the Taliban have carried out scores of bombings and shootings across Pakistan against minority Shiites. One of the deadliest groups has been the Punjab-based Lashkar-e-Jhangvi, which also claimed responsibility for gunning down 26 Shiites this summer riding in a bus through southwestern Baluchistan province.

Like al-Qaida, the Taliban and other Sunni extremist groups, Lashkar it regards Shiite Muslims as nonbelievers and potential targets for attack.

Pakistan is a majority Sunni state, with Shiites making up about 15 percent of the 180 million population. Most Sunnis and Shiites live together peacefully, but tensions have existed for decades.

The last incident of violence between Shiites and Sunnis following the U.S. invasion 10 years ago occurred in early 2006, during Ashoura commemorations in the western city of Herat. During those riots, blamed on Islamic extremists, five people were killed and more than 50 injured.

The Kabul shrine attacked is close to the palace where Karzai lives and who is in Europe to attend an international conference on Afghanistan. It is named after Abul Fazl, who was an adviser to a 14th century Mogul emperor. The shrine and its blue minaret is one of Kabul's better known shrines. It is located in Murad Khane area near the Kabul river, a district that has been listed by the World Monuments Fund as one of its 100 most endangered sites of cultural heritage.

Astronomers find fastest rotating star

ScienceDaily (Dec. 5, 2011) ? The European Southern Observatory's Very Large Telescope has picked up the fastest rotating star found so far. This massive bright young star lies in our neighbouring galaxy, the Large Magellanic Cloud, about 160,000 light-years from Earth. Astronomers think that it may have had a violent past and has been ejected from a double star system by its exploding companion.

An international team of astronomers has been using ESO's Very Large Telescope at the Paranal Observatory in Chile, to make a survey of the heaviest and brightest stars in the Tarantula Nebula, in the Large Magellanic Cloud. Among the many brilliant stars in this stellar nursery the team has spotted one, called VFTS 102 [1], that is rotating at more than two million kilometres per hour -- more than three hundred times faster than the Sun [2] and very close to the point at which it would be torn apart due to centrifugal forces. VFTS 102 is the fastest rotating star known to date [3].

The astronomers also found that the star, which is around 25 times the mass of the Sun and about one hundred thousand times brighter, was moving through space at a significantly different speed from its neighbours [4].

"The remarkable rotation speed and the unusual motion compared to the surrounding stars led us to wonder if this star had had an unusual early life. We were suspicious." explains Philip Dufton (Queen's University Belfast, Northern Ireland, UK), lead author of the paper presenting the results.

This difference in speed could imply that VFTS 102 is a runaway star -- a star that has been ejected from a double star system after its companion exploded as a supernova. This idea is supported by two further clues: a pulsar and an associated supernova remnant in its vicinity [5].

The team has developed a possible back story for this very unusual star. It could have started life as one component of a binary star system. If the two stars were close, gas from the companion could have streamed over and in the process the star would have spun faster and faster. This would explain one unusual fact -- why it is rotating so fast. After a short lifetime of about ten million years, the massive companion would have exploded as a supernova -- which could explain the characteristic gas cloud known as a supernova remnant found nearby. The explosion would also have led to the ejection of the star and could explain the third anomaly -- the difference between its speed and that of other stars in the region. As it collapsed, the massive companion would have turned into the pulsar that is observed today, and which completes the solution to the puzzle.

Although the astronomers cannot yet be sure that this is exactly what happened, Dufton concludes "This is a compelling story because it explains each of the unusual features that we've seen. This star is certainly showing us unexpected sides of the short, but dramatic lives of the heaviest stars."

Notes:

[1] The name VFTS102 refers to the VLT-FLAMES Tarantula Survey made using the Fibre Large Array Multi Element Spectrograph (FLAMES) on ESO's Very Large Telescope.

[2] An aircraft travelling at this speed would take about one minute to circle Earth at the equator.

[3] Some stars end their lives as compact objects such as pulsars (see note [5]), which may spin much more rapidly than VFTS 102, but they are also very much smaller and denser and do not shine by thermonuclear reactions like normal stars.

[4] VFTS 102 is moving at roughly 228 kilometres per second, which is slower than other similar stars in the region by about 40 kilometres per second.

[5] Pulsars are the result of supernovae. The core of the star collapses to a very small size creating a neutron star which spins very rapidly and emits powerful jets of radiation. These jets create a regular "pulse" as seen from Earth as the star rotates around its axis. The associated supernova remnant is a characteristic cloud of gas blown away by the shock wave resulting from the collapse of the star into a neutron star.
