Assad Calls On Syrians to Defend the Country












President Bashar Assad called on Syrians to defend their country against Islamic extremists seeking to destroy the nation, dismissing any prospect of dialogue with the "murderous criminals" he says are behind the uprising even as he outlined his vision for a peaceful settlement to the civil war.



In a one-hour speech to the nation in which he appeared confident and relaxed, Assad struck a defiant tone, ignoring international demands for him to step down and saying he is ready to hold a dialogue — but only with those "who have not betrayed Syria."



He offered a national reconciliation conference, elections and a new constitution but demanded regional and Western countries stop funding and arming rebels trying to overthrow him first.



Syria's opposition swiftly rejected the proposal. Those fighting to topple the regime, including rebels on the ground, have repeatedly said they will accept nothing less than the president's departure, dismissing any kind of settlement that leaves him in the picture.



"It is an excellent initiative that is only missing one crucial thing: His resignation," said Kamal Labwani, a veteran secular dissident and member of the opposition's Syrian National Coalition umbrella group.



"All what he is proposing will happen automatically, but only after he steps down," Labwani told The Associated Press by telephone from Sweden.

On top of that, Assad's new initiative is reminiscent of symbolic changes and concessions that his government made earlier in the uprising, which were rejected at the time as too little too late.



Speaking at the Opera House in central Damascus, Assad told the hall packed with supporters — who frequently broke out in cheers and applause — that "we are in a state of war."



"We are fighting an external aggression that is more dangerous than any others, because they use us to kill each other," he said. "It is a war between the nation and its enemies, between the people and the murderous criminals."



Assad has rarely spoken since the uprising against his rule began in March 2011, and Sunday's speech was his first since June. His last public comments came in an interview in November to Russian TV in which he vowed to die in Syria.



On Sunday, he seemed equally confident in his troops' ability to crush the rebels fighting his rule, even as they edge in closer than ever to his seat of power, Damascus.



British Foreign Secretary William Hague said Assad's speech was "beyond hypocritical." In a message posted on his official Twitter feed, Hague said "empty promises of reform fool no one."



EU foreign policy chief Catherine Ashton's office said in a statement that the bloc will "look carefully if there is anything new in the speech but we maintain our position that Assad has to step aside and allow for a political transition."



Turkey's Foreign Minister Ahmet Davutoglu said Assad's speech was filled with "empty promises" and repetitive pledges of reform by a president appeared out of touch with reality of the Syrian people.



"It seems (Assad) has shut himself in his room, and for months has read intelligence reports that are presented to him by those trying to win his favor," Davutoglu told reporters in the Aegean port city of Izmir on Sunday.



Turkey is a former ally of Damascus, and while Ankara first backed Assad after the uprising erupted, it turned against the regime after its violent crackdown on dissent.

Silent Skype calls can hide secret messages









































Got a secret message to send? Say it with silence. A new technique can embed secret data during a phone call on Skype. "There are concerns that Skype calls can be intercepted and analysed," says Wojciech Mazurczyk at the Institute of Telecommunications in Warsaw, Poland. So his team's SkypeHide system lets users hide extra, non-chat messages during a call.












Mazurczyk and his colleagues Maciej Karaƛ and Krysztof Szczypiorski analysed Skype data traffic during calls and discovered an opportunity in the way Skype "transmits" silence. Rather than send no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.












The team hijacks these silence packets, injecting encrypted message data into some of them. The Skype receiver simply ignores the secret-message data, but it can nevertheless be decoded at the other end, the team has found. "The secret data is indistinguishable from silence-period traffic, so detection of SkypeHide is very difficult," says Mazurczyk. They found they could transmit secret text, audio or video during Skype calls at a rate of almost 1 kilobit per second alongside phone calls.












The team aims to present SkypeHide at a steganography conference in Montpellier, France, in June.

British team flies to Myanmar for buried Spitfire planes






LONDON: A team hunting for a rumoured hoard of World War II Spitfire planes in Myanmar left Britain on Saturday to start the dig, comparing the excitement to the discovery of Tutankhamun's tomb.

The 21-strong team believe there could be 36 of the iconic single-seat British fighter aircraft buried in sealed crates up to 10 metres (33 feet) beneath Yangon airport, a wartime airfield, with more at two other sites in Myanmar.

Britain, the former colonial power in what was then Burma, is thought to have buried the brand new planes in 1945 as they were surplus by the time they arrived by sea.

The dig, set to start at Yangon airport on Monday, has excited military history and aviation enthusiasts around the world.

There are thought to be fewer than 50 airworthy Spitfires left in the world and the digs could potentially double their number if they remain in pristine condition.

Project leader David Cundall told AFP that getting a first glimpse of Spitfire would be like the 1922 discovery of Egyptian pharaoh Tutankhamun's tomb.

"It's similar to the Tutankhamun find in Egypt many years ago and Lord Carnarvon said to Howard Carter when he was looking through the hole 'can you see anything?' , and he said, 'yes, wonderful things', and I'm going to say the same thing," he said.

Cundall, a farmer and aircraft enthusiast, has been on a long chase for the rumoured lost Spitfires.

"We've interviewed eight eyewitnesses pointing to the exact spot," he said.

"Some have told us in great detail how they were buried, the depth and the configuration all fits correctly the location.

"After 17 years you do get a little bit weary but there's now enough energy left in me to finish the project, and I'd like to do it as soon as possible: get the airplanes back to the UK, have them restored and see them flying at airshows."

Speaking at London Heathrow Airport before flying out, lead archeologist Andy Brockman said: "The evidence so far takes us to a particular part of former RAF Mingaladon. What our job is now is to follow those strands of evidence and turn all the rumour and speculation and hypothesis into facts in the ground from the archaeology that we discover."

Cundall's share of any planes found will be 30 per cent, his agents will have 20 per cent, while the Myanmar government will keep 50 per cent, according to agreements they have signed.

"There are very few Spitfires that you can actually say are 100 per cent original; these are brand new Mark XIV Spitfires," he said.

"The fuselages were wrapped in brown paper, grease paper to preserve them, the wooden joints were tarred to keep the water out.

"They did go to an awful lot of trouble to bury these.

"It was a tool of war, yes, but I'm trying to make it a tool of friendship to bring Burma and Britain closer together."

Google may need history lesson on blocking rivals' products




With its decision to block Windows Phone users from accessing Google Maps, Google isn't the first browser maker to block users from accessing content with a competitive product. Microsoft has done the same in the distant and not-so-distant past. But that's still no excuse for what looks like nothing other than a petty, short-sighted move on Google's part.


Back in 2001, Microsoft was slammed for making MSN.com incompatible with browsers other than IE. Microsoft officials said the problem wasn't intentional and rewrote the site to work with non-Microsoft browsers. But the outcry -- even from the head of the Worldwide Web Consortium, Tim Berners-Lee -- was fast and furious.


More recently, I've heard from users frustrated because they couldn't access the Microsoft Careers site using Chrome. (A quick check today indicates those problems seem to have been resolved, either by Microsoft or Google.) And I can verify I've been unable to listen/view Webcasts on Microsoft's Investor site using anything other than IE, though this issue also seems to have been fixed some time in the last few days/weeks. Huzzah!


Am I citing Microsoft's transgressions to excuse Google? Hardly. Given that Windows Phone has only 3 percent market share in the U.S., compared with
Android's 54 percent, one could argue Google doesn't have the time/incentive to make sure its Maps work well with Windows Phone. I'm not buying that, though.


As others have noted and seemingly proved, Google's blocking of IE/Windows Phone users isn't attributable to Microsoft using its own Trident rendering engine instead of Webkit -- despite Google's claims to the contrary.


Google Maps works fine in IE10 on
Windows 8 and Windows RT and those products use the same Trident rendering engine that Windows Phone does. The two IE10 browsers are not completely identical; there are a number of features in IE10 on Windows 8 that aren't supported in IE10 on Windows Phone, including some programming interfaces, ActiveX, and VBScript. Nonetheless, the evidence is mounting that Google intentionally is redirecting Windows Phone users who are attempting to access its maps via IE.


Maybe the Googlers are trying to pay back Microsoft for trying and largely failing to get the U.S. Federal Trust Commission to take antitrust action against the company. Or maybe they're mad that Microsoft is managing to convince many/most of the Android licensees to pay Microsoft patent-licensing royalties to head off potential legal action.


I don't know how many of we the 3 percent need/want to use Google Maps via the browser. Whether it's a few (including me, on more than one occasion) or many, the move to block Windows Phone users still looks short-sighted. Wouldn't it make more sense to encourage those using your competitors' products (Bing, IE) to access your technology instead of theirs? Maybe you'll win over a new customer or three in the process.


I'm not the first to say it, and I'm sure I won't be the last. Google should brush up on its history lessons. It's emulating the old Microsoft. Even though Google largely beat the antitrust rap this time, maybe its luck won't hold out forever....

Debt Limit Negotiating Tactic? No Negotiating


ap obama ac 130102 wblog In Fiscal Wars No Negotiation Is a Negotiating Tactic

President Barack Obama and Vice President Joe Biden walk away from the podium after Obama made a statement regarding the passage of the fiscal cliff bill in the Brady Press Briefing Room at the White House in Washington, Tuesday, Jan. 1, 2013. (AP Photo/Charles Dharapak)


Analysis


New for 2013: In the Washington, D.C. fiscal wars we’ve gone from everything must be on the table to politicians declaring they won’t debate.


The fiscal cliff deal either averted disaster or compounded the problem, depending on who you ask. It certainly created new mini-cliffs in a few months as Congress and the president square off on the debt ceiling, spending cuts and government funding. But it also made sure the vast majority of Americans won’t see as big a tax hike as they might have.


President Obama was pretty clear late on New Year’s night as he reacted to Congress’s passage of a bill to take a turn away from the fiscal cliff. He won’t negotiate with Republicans about the debt ceiling.


“Now, one last point I want to make,” said the president, before wrapping up and hopping on Air Force One for a redeye to Hawaii. “While I will negotiate over many things, I will not have another debate with this Congress over whether or not they should pay the bills that they’ve already racked up through the laws that they passed.”


(Read more here about the Fiscal Cliff)


That’s pretty clear. No debt ceiling negotiation. Then he added for emphasis: ”Let me repeat: We can’t not pay bills that we’ve already incurred. If Congress refuses to give the United States government the ability to pay these bills on time, the consequences for the entire global economy would be catastrophic — far worse than the impact of a fiscal cliff.”


But in Washington, saying you won’t do something these days has almost become like an opening bid. At least, that’s how Republicans are treating the president’s line in the sand.


“The president may not want to have a fight about government spending over the next few months, but it’s the fight he is going to have because it’s a debate the country needs,” wrote Senate Minority Leader Mitch McConnell, the Kentucky Republican, in an op-Ed on Yahoo! News about 36 hours later. “For the sake of our future, the president must show up to this debate early and convince his party to do something that neither he nor they have been willing to do until now.”


“We simply cannot increase the nation’s borrowing limit without committing to long overdue reforms to spending programs that are the very cause of our debt,” McConnell said.


The national debt is soon set to reach $16.4 trillion. That’s not a problem that can be solved with one bill or budget. And the two sides will have to figure out some sort of way to talk about entitlement/social safety net reform – meaning things like Medicare, Medicaid, and Social Security – in addition to cutting spending and, most importantly, hope for an improving economy, to deal with those deficits.


House Speaker John Boehner, who has several times now failed to reach a big, broad fiscal deal with President Obama, told colleagues, according to The Hill newspaper, that he’s done with secret White House negotiations. He wants to stick with the constitutional way of doing things, with hearings and bills that are debated on Capitol Hill rather than hatched by the vice president and Senate Republicans.


Okay. Obama won’t negotiate on the debt ceiling. McConnell won’t not negotiate on the debt ceiling. Boehner doesn’t to do things by the book.


But McConnell won’t negotiate on taxes any more.


“Predictably,” McConnell had written earlier in his post, “the president is already claiming that his tax hike on the ‘rich’ isn’t enough. I have news for him: the moment that he and virtually every elected Democrat in Washington signed off on the terms of the current arrangement, it was the last word on taxes. That debate is over.”


It’s a new chapter in the ongoing fiscal saga in Washington. Back when the two sides were talking about a grand bargain or a big deal – some sort of all-inclusive reform that would right the listing deficit with one flip of the rudder – the popular trope was that “everything must be on the table.” That’s basically how Obama put it back in the summer of 2011 when he and Boehner failed to reach a grand bargain. He wanted higher taxes – they were calling them revenues back then. More recently, after Obama won the election and when he and Boehner were trying to hammer out another grand bargain to avert the fiscal cliff, Boehner wanted entitlements on the table. That means he wanted to find ways to curb future spending.


Both sides are declaring they won’t debate certain points, but this far – a full two months – before the mini-cliffs start, those are easier declarations to make than they will be when the government is in danger of defaulting or shutting down.


Even though they’re trying to take elements off the table, both men hope that coming negotiations can be a little more cordial and a little less down-to-the wire.


“Over the next two months they need to deliver the same kind of bipartisan resolution to the spending problem we have now achieved on revenue — before the 11th hour,” wrote McConnell.


“The one thing that I think, hopefully, in the New Year we’ll focus on is seeing if we can put a package like this together with a little bit less drama, a little less brinksmanship, not scare the heck out of folks quite as much,” said Obama.


That’ll be tough if neither side will talk about what the other side wants to talk about.

Vesta's crater carbon came from asteroids



Lisa Grossman, reporter

The mini-planet Vesta took a beating in its past - but the ordeal may have delivered carbon to its surface. A new map of dark material in Vesta's craters shows that the huge rocks that formed them brought carbonaceous material along for the ride.





Vesta's surface is marked by material as black as coal, most of it on and around craters like the one in the 3D model above. It wasn't clear, though, where this carbon-rich material had come from. The answer seems to lie in images taken last year that show two gigantic impact craters which must be the results of 50 to 60-kilometre-wide rocks smacking into Vesta's southern hemisphere.



New analysis shows that the first impact brought something with it. A team led by Vishnu Reddy from the Max Planck Institute for Solar System Research in Lindau, Germany, mapped the dark stuff on Vesta's surface. They found that it is concentrated around the huge southern craters, and figured that it arrived in the earlier of the two impacts, 2 to 3 billion years ago. Computer simulations of the impact confirmed that it could have created the patterns of dark material we see today.



That suggests that carbon was delivered to Vesta via an asteroid. And Vesta was probably not the only object to receive such a package, the team says. The same delivery system could have brought one of the essential building blocks of life to Earth.

Primary schools to receive new teachers twice a year






SINGAPORE: From 2015, primary schools will receive a new batch of teachers twice each year - instead of the current arrangement where new teachers are deployed in June - following changes to the timing of the annual intake of the Postgraduate Diploma in Education (PGDE) (Primary) programme.

The PGDE (Primary) programme is a one-year diploma course conducted at the National Institute of Education. Currently, its graduates are deployed along with their counterparts in the Diploma in Education and Bachelor of Arts (Education) or Bachelor of Science (Education) programmes.

With the change, graduates from the PGDE (Primary) will be posted to their schools in January, instead of June.

Responding to TODAY's queries, the Ministry of Education (MOE) said the key reason for the change is to "better support the schools' manpower needs at the primary level".

Its spokesperson said: "This will allow for two batches of trained teachers to graduate from the different programmes in NIE to be posted to the primary schools ... each year, thereby reducing the schools' waiting time to fill vacancies for trained teachers."

To effect the change, the intake for PGDE (Primary) will be shifted from July to January - starting this year.

The MOE spokesperson said that email notifications were sent in April last year to those who were due to enrol in the programme in July this year - many of whom are currently doing contract teaching - but will now start their course in January next year.

"School leaders with untrained teachers in their schools affected by this change were similarly informed," she said.

While primary school principals whom TODAY spoke to welcomed the change, one untrained teacher who had been due to start the PGDE (Primary) programme this year was upset that he has to wait another six months to begin classes.

The 30-year-old teacher, who wanted to be known only as Mr Tan, said he found out about the change in February last year after MOE replied to his email query on the starting date of his course.

He claimed that he has not received an official notification.

After spending the past year doing contract teaching, Mr Tan said he would have to continue for another year because of the change.

It is not clear how many prospective trainee teachers are affected by the shift in the timing of the intake this year, as the MOE did not reply to queries on the intake size of the PGDE (Primary).

The current teaching force is about 33,000 strong. On average, 2,000 new teachers are recruited each year.

Principals said the change was timely, given how more teachers are taking up MOE initiatives such as the Part-Time Teaching Scheme (PTTS), and the enhanced Professional Development Leave (PDL) scheme which allow teachers with at least six years' service to take leave at half pay to undergo professional development.

Punggol View Primary Principal Kelvin Tay said: "Having two batches would ease issues that come up when teachers are away, such as on maternity leave or professional development, and it would help fill deployment gaps."

As the school calendar begins in January, Nanyang Primary School Principal Lee Hui Feng noted that getting new teachers in the same month will reduce changes to teaching personnel in the middle of the school year.

Apple to buck the trend in sour computer market, says analyst



Apple's iPad

Apple's iPad.



(Credit:
Apple)


Apple will be one of the few companies to thrive this year in the midst of weak computer buying from the corporate crowd.


Global corporate spending on Windows PCs and
tablets fell by 4 percent last year, according to a report out yesterday from Forrester Research. Spending is likely to be flat this year as companies slowly replace old Windows PCs with new
Windows 8 devices.


But Apple is "one vendor that will buck this trend," the research firm said in its report. The company is expected to sell $7 billion worth of Macs and $11 billion of iPads to corporate customers this year. Those numbers are predicted to rise to $8 billion worth of Macs and $13 billion of iPads next year.


Despite a decline in PC spending, Windows 8 computers still dominate the corporate market. But Apple has seen greater demand for the Macs among business users over the past few years. And more companies have adopted or at least allowed the use of the
iPad by employees at a time when the overall PC industry is hurting.

"Unless the vendor's name is Apple or perhaps Lenovo, the computer equipment market will still struggle in 2013, with no better growth in sight until 2014," Forrester said in its report. "The 4 percent growth in PCs in 2013 looks more promising, but that is mostly due to growth in tablets, which we count in the broader PC category. It will not be until 2014 when the economic expansion strengthens that CIOs will feel confident enough to commit funds to refreshing their aging stack of PCs, servers, storage devices, and peripherals."

Forrester is eyeing an 8 percent increase in Windows 8 devices and PCs come 2014. But even that growth will be less than the double-digit gains projected for Apple, Android, and Linux products.
