Apple plans to issue fix for iOS 6.1 Exchange sync bug

Label:



Apple announced today that it has identified the cause of a sync problem between iOS 6.1 devices and Microsoft's Exchange service and said it would issue a fix in the next software update.


Almost immediately after Apple release
iOS 6.1 at the end of January, Microsoft Exchange administrators noticed that devices running the new OS version were causing "excessive logging" on servers. The issue was traced back to Apple code used to synchronize a user's Exchange mailbox and calendar events.


The announcement, made on Apple's support page, did not indicate a timeframe for that software but offered advice for avoiding the issue:


Apple has identified a fix and will make it available in an upcoming software update. In the meantime, you can avoid this bug by not responding to an exception to a recurring event on your iOS device. If you do experience the symptoms described above, disable then reenable the Exchange calendar on your iOS device ...




Apple noted that affected users may notice increased network activity or reduced battery life on their iOS device. The increased activity will appear on Exchange Server logs and may lead to the device being blocked. The issue affects iOS 6.1 devices running Microsoft Exchange 2010 SP1 or later, or Microsoft Exchange Online (Office365).

On January 28, Apple released iOS 6.1, the first major update to iOS 6 since September. Along with a few new minor features and bug fixes, the new software also prompted numerous reports of sudden and significant battery drain and at least one case of an overheating battery. Suspicion immediately fell to upon the excessive logging issue with Microsoft Exchange.

Are Honeybees Losing Their Way?

Label:


A single honeybee visits hundreds, sometimes thousands, of flowers a day in search of nectar and pollen. Then it must find its way back to the hive, navigating distances up to five miles (eight kilometers), and perform a "waggle dance" to tell the other bees where the flowers are.


A new study shows that long-term exposure to a combination of certain pesticides might impair the bee's ability to carry out its pollen mission.


"Any impairment in their ability to do this could have a strong effect on their survival," said Geraldine Wright, a neuroscientist at Newcastle University in England and co-author of a new study posted online February 7, 2013, in the Journal of Experimental Biology.


Wright's study adds to the growing body of research that shows that the honeybee's ability to thrive is being threatened. Scientists are still researching how pesticides may be contributing to colony collapse disorder (CCD), a rapid die-off seen in millions of honeybees throughout the world since 2006.


"Pesticides are very likely to be involved in CCD and also in the loss of other types of pollinators," Wright said. (See the diversity of pollinating creatures in a photo gallery from National Geographic magazine.)


Bees depend on what's called "scent memory" to find flowers teeming with nectar and pollen. Their ability to rapidly learn, remember, and communicate with each other has made them highly efficient foragers, using the waggle dance to educate others about the site of the food source.



Watch as National Geographic explains the waggle dance.


Their pollination of plants is responsible for the existence of nearly a third of the food we eat and has a similar impact on wildlife food supplies.


Previous studies have shown certain types of pesticides affect a bee's learning and memory. Wright's team wanted to investigate if the combination of different pesticides had an even greater effect on the learning and memory of honeybees.


"Honeybees learn to associate floral colors and scents with the quality of food rewards," Wright explained. "The pesticides affect the neurons involved in these behaviors. These [affected] bees are likely to have difficulty communicating with other members of the colony."


The experiment used a classic procedure with a daunting name: olfactory conditioning of the proboscis extension reflex. In layman's terms, the bee sticks out its tongue in response to odor and food rewards.


For the experiment, bees were collected from the colony entrance, placed in glass vials, and then transferred into plastic sandwich boxes. For three days the bees were fed a sucrose solution laced with sublethal doses of pesticides. The team measured short-term and long-term memory at 10-minute and 24-hour intervals respectively. (Watch of a video of a similar type of bee experiment.)


This study is the first to show that when pesticides are combined, the impact on bees is far worse than exposure to just one pesticide. "This is particularly important because one of the pesticides we used, coumaphos, is a 'medicine' used to treat Varroa mites [pests that have been implicated in CCD] in honeybee colonies throughout the world," Wright said.


The pesticide, in addition to killing the mites, might also be making honeybees more vulnerable to poisoning and effects from other pesticides.


Stephen Buchmann of the Pollinator Partnership, who was not part of Wright's study, underscored how critical pollinators are for the world. "The main threat to pollinators is habitat destruction and alteration. We're rapidly losing pollinator habitats, natural areas, and food—producing agricultural lands that are essential for our survival and well being. Along with habitat destruction, insecticides weaken pollinators and other beneficial insects."

Dorner Not IDed, But Manhunt Considered Over

Label:












Though they have not yet identified burned remains found at the scene of Tuesday's fiery, armed standoff, San Bernardino, Calif., officials consider the manhunt over for Christopher Dorner, the fugitive ex-cop accused of going on a killing spree.


"The events that occurred yesterday in the Big Bear area brought to close an extensive manhunt," San Bernardino County Sheriff John McMahon told reporters this evening.


"I cannot absolutely, positively confirm it was him," he added.


However, he noted the physical description of the suspect authorities pursued to a cabin at the standoff scene, as well as the suspect's behavior during the chase and standoff, matched Dorner, 33.


The charred remains of the body believed to be Dorner were removed from the cabin high in the San Bernardino Mountains near Big Bear, Calif., the apparent site of Dorner's last stand. Cornered inside the mountain cabin Tuesday, the suspect shot at cops, killing one deputy and wounding another, before the building was consumed by flames.


"We did not intentionally burn down that cabin to get Mr. Dorner out," McMahon said tonight, though he noted pyrotechnic canisters known as "burners" were fired into the cabin during a tear gas assault in an effort to flush out Dorner. The canisters generate high temperatures, he added.


The deputies wounded in the firefight were airlifted to a nearby hospital, where one died, police said.

The deceased deputy was identified tonight as Det. Jeremiah MacKay, 35, a 15-year veteran and the father of two children -- a daughter, 7, and son, 4 months old.


"Our department is grieving from this event," McMahon said. "It is a terrible deal for all of us."


The Associated Press quoted MacKay on the Dorner dragnet Tuesday, noting that he had been on patrol since 5 a.m. Saturday.


"This one you just never know if the guy's going to pop out, or where he's going to pop out," MacKay said. "We're hoping this comes to a close without more casualties. The best thing would be for him to give up."


The wounded deputy, identified as Alex Collins, was undergoing multiple surgeries for his wounds at a hospital, McMahon said, but was expected to make a full recovery.


Before the final standoff, Dorner was apparently holed up in a snow-covered cabin in the California mountains just steps from where police had set up a command post and held press conferences during a five-day manhunt.


The manhunt for Dorner, one of the biggest in recent memory, led police to follow clues across the West and into Mexico, but it ended just miles from where Dorner's trail went cold last week.


Residents of the area were relieved today that after a week of heightened police presence and fear that Dorner was likely dead.


"I'm glad no one else can get hurt and they caught him. I'm happy they caught the bad guy," said Ashley King, a waitress in the nearby town of Angelus Oaks, Calif.


Hundreds of cops scoured the mountains near Big Bear, a resort area in Southern California, since last Thursday using bloodhounds and thermal-imaging technology mounted to helicopters, in the search for Dorner. The former police officer and Navy marksman was suspected to be the person who killed a cop and cop's daughter and issued a "manifesto" declaring he was bent on revenge and pledging to kill dozens of LAPD cops and their family members.


But it now appears that Dorner never left the area, and may have hid out in an unoccupied cabin just steps from where cops had set up a command center.

Obama keeps faith in science and warns of cyber threats

Label:


Peter Aldhous, San Francisco bureau chief
"IT IS our unfinished task to restore the basic bargain that built this country - the idea that if you work hard and meet your responsibilities, you can get ahead."

In adopting the phrase "unfinished task" as a signature motif for his 2013 State of the Union address, President Barack Obama signalled a return to familiar themes. For those who care about investment in science, that was a reassuring message. 
The fight against global warming and the importance of technology to protect national security also got high billing. On the latter, Obama signaled that hacking skills, rather than kilotons, are increasingly a crucial currency, promising a new focus on combating cyberattacks - paralleled by negotiated cuts to the US nuclear arsenal. 




In a combative speech designed to counter Republican opponents who want to cut the budget deficit by curbing spending on Obama's priorities - including education and research - the President made the case for continued investment in innovation.
"Every dollar we invested to map the human genome returned $140 to our economy. Today, our scientists are mapping the human brain to unlock the answers to Alzheimer's; developing drugs to regenerate damaged organs; devising new material to make batteries ten times more powerful. Now is not the time to gut these job-creating investments in science and innovation. Now is the time to reach a level of research and development not seen since the height of the Space Race."
The estimate of a 140:1 return on investment in genomics comes from a 2011 study by the Battelle Memorial Institute in Columbus, Ohio. While the precise numbers from that analysis have been questioned, the importance of continued innovation to America's future economic competitiveness has been stressed in multiple reports, notably from the US National Academies. 
"Now our enemies are also seeking the ability to sabotage our power grid, our financial institutions, and our air traffic control systems. We cannot look back years from now and wonder why we did nothing in the face of real threats to our security and our economy."
Obama called on Congress to pass new legislation to counter threats from hackers backed by hostile governments. That won't be easy: last year, a bill that would have demanded that companies meet minimum standards for cybersecurity, and report if they are attacked, foundered amid complaints that it would impose large costs on US businesses.

Man charged with causing death of colleague through negligence

Label:





SINGAPORE: A man has been charged with causing the death of his 62-year-old colleague through negligence.

T Magesvaran A/L Tambisamy, 39, is accused of causing fellow production worker, Fan Chow Lin's death on 10 October 2012 at Idemitsu Lube Singapore in Pandan Road.

The alleged incident took place when the accused was operating the forklift to lift a tote tank designed to hold up to 2000 litres of liquids.

While doing so, Magesvaran is said to have mistakenly stepped on the accelerator instead of the brake, therefore causing the forklift to move forward and knocking into the tank.

Mr Fan was crushed between two tanks.

For causing a man's death due to negligence, the accused faces the maximum penalty of a jail term of up to two years and a fine.

Surface Pro as a gaming rig? It's ready and able

Microsoft's new Intel-powered tablet isn't being advertised as a gaming platform, but maybe it should.


The Surface Pro handles Diablo III and Portal 2 at near-maximum settings, according to a post by Jason Evangelho at Forbes.com.


Gamers "represent an important -- and arguably sizable -- potential demographic for Microsoft. As the company knows from its wildly successful
Xbox platform," he wrote.


At the moment, Microsoft is marketing Surface as a business tool, with no mention of its gaming chops.



The closest it gets is ad copy about Intel's laptop-class Core i5 processor and the ability to run applications like Adobe Photoshop.


That Intel hardware makes it rare bird for a
tablet. With a few exceptions like the Samsung ATIV Smart PC Pro 700T, tablets today use either Intel's pokey Atom processor or -- relative to Intel's mainstream chips -- slower ARM processors.


Other specs lend the tablet to running games: it packs a fast solid-state drive (often used on gaming rigs) and 1,920x1,080 display.


"The Surface Pro handles Diablo III at 1920x1080 resolution with most specs except shadows maxed out," wrote Evangelho.


Not bad for a tablet.

State of the Union: Obama Pushes Job Creation

Label:












Pursuing an aggressive and diverse early second-term agenda, President Obama turned his focus Tuesday night squarely to the economy, using his State of the Union address to unveil new government initiatives aimed at creating jobs.


The defining duty of the new Congress and new administration is to "reignite the true engine of America's economic growth -- a rising, thriving middle class," Obama said Tuesday night from the House chamber.


"That must be the North Star that guides our efforts," he said.


Obama's proposals had a familiar ring, including re-packaged economic ideas but also offering several bold new measures aimed at boosting the middle class.


None of the proposals would add to the deficit "by a single dime," Obama pledged, with costs offset by savings carved out in the budget and from money saved from ending two wars.


"It's not a bigger government we need, but a smarter government that sets priorities and invests in broad-based growth," Obama said.


For the first time as president, Obama called for raising the minimum wage from $7.25 to $9.00 an hour by 2015. He proposed to ensure future increases by indexing the minimum wage to inflation.


He proposed a national goal of universal pre-school education, an effort to help states provide tens of thousands of low- to middle-income four-year-old children access to quality public education from an earlier age.

And, to heal the nation's crumbling roads and bridges, Obama offered a $50 billion "fix it first" infrastructure program that would prioritize repair of existing structures before building new ones.


"Every day, we should ask ourselves three questions as a nation," Obama said. "How do we attract more jobs to our shores? How do we equip our people with the skills needed to do those jobs? And how do we make sure that hard work leads to a decent living?"


Answers to those questions, the president suggested, include redoubling investments in clean energy technologies -- a step which he said would both benefit the environment and reduce U.S. dependence on foreign oil.


"For the sake of our children and our future, we must do more to combat climate change," he said.


He called for doubling the amount of renewable electricity generation in the U.S. by 2020, and announced an energy version of his "Race to the Top" education program that would give states grants for the best energy efficiency programs.

In tandem with his economic focus, Obama announced the withdrawal of 34,000 U.S. troops from Afghanistan by this time next year, cutting in half the current force and marking a quickened pace for the final exit of U.S. combat forces by a 2014 deadline.


There are currently 66,000 U.S. troops serving in Afghanistan. Obama has vowed to bring nearly all of them home by the end of next year, though a small contingent will likely remain to train Afghan forces and assist counterterrorism operations, officials have said.


Obama touched briefly on his recently-unveiled proposals to overhaul the nation's immigration system, expand rights for gay and lesbian Americans and curb an epidemic of gun violence.


With dozens of victims of gun violence looking on from the House gallery, including former Rep. Gabby Giffords, and families of victims from shootings at Newtown, Conn., Oak Creek, Wisc., and Aurora, Colo., Obama made an emotional plea for an up-or-down vote on his gun control plan.


"Each of these proposals deserves a vote in Congress," he said of proposed restrictions on assault-style weapons and high capacity magazines, and enhanced background checks, among other measures.


"If you want to vote no, that's your choice," he said. "But these proposals deserve a vote. Because in the two months since Newtown, more than a thousand birthdays, graduations and anniversaries have been stolen from our lives by a bullet from a gun."
