Comments Off on Can BB Benefit From The WhatsApp Deal?
Facebook Inc’s awe-inspiring $19 billion bid for fast-growing mobile-messaging startup WhatsApp sent shares of BlackBerry Ltd surging after the closing bell as early as Wednesday, as investors were cheered by the lofty valuation for the messaging platform.
The deal sent shares in BlackBerry up as much as 9 percent in trading after the bell because it put a rough valuation metric around the smartphone maker’s own BlackBerry Messaging service.
BlackBerry Messaging, or BBM as it is more commonly known, was a pioneering mobile-messaging service, but its user base has failed to keep pace with that of WhatsApp, in part because BlackBerry had long refused to open the service to users on other platforms.
WhatsApp, with a user base of some 450 million, has grown rapidly. Its service works on Apple Inc’s iOS platform, Google Inc’s market-dominating Android operating system, along with devices powered by both the Windows and BlackBerry operating systems.
BBM remains popular, even though BlackBerry devices have waned in popularity. Late last year, the Waterloo, Ontario-based smartphone maker finally opened the messaging platform to users of iPhones and Android devices, and the service currently has over 80 million active users.
However, investors have attributed little value to the asset within the company. On Tuesday, Raymond James analyst Steven Li, in a note to clients, broke out a sum-of-parts valuation of the company and pegged the value of BBM at merely $240 million, or $3 per user.
Facebook’s valuation of WhatsApp translates into roughly $42 per user, and that could lead investors and analysts to rethink their valuation of the asset within BlackBerry.
BlackBerry has given no indication it is keen to sell the asset. While there has been some speculation that BlackBerry may seek to carve out the unit, or even sell it, the company’s new Chief Executive John Chen has so far said that BBM remains a core asset for the company.
Will Arm/Atom CPUs Replace Xeon/Opteron?
Comments Off on Will Arm/Atom CPUs Replace Xeon/Opteron?
Analyst are saying that smartphone chips could one day replace the Xeon and Opteron processors used in most of the world’s top supercomputers. In a paper in a paper titled “Are mobile processors ready for HPC?” researchers at the Barcelona Supercomputing Center wrote that less expensive chips bumping out faster but higher-priced processors in high-performance systems.
In 1993, the list of the world’s fastest supercomputers, known as the Top500, was dominated by systems based on vector processors. They were nudged out by less expensive RISC processors. RISC chips were eventually replaced by cheaper commodity processors like Intel’s Xeon and AMD Opteron and now mobile chips are likely to take over.
The transitions had a common thread, the researchers wrote: Microprocessors killed the vector supercomputers because they were “significantly cheaper and greener,” the report said. At the moment low-power chips based on designs ARM fit the bill, but Intel is likely to catch up so it is not likely to mean the death of x86.
The report compared Samsung’s 1.7GHz dual-core Exynos 5250, Nvidia’s 1.3GHz quad-core Tegra 3 and Intel’s 2.4GHz quad-core Core i7-2760QM – which is a desktop chip, rather than a server chip. The researchers said they found that ARM processors were more power-efficient on single-core performance than the Intel processor, and that ARM chips can scale effectively in HPC environments. On a multi-core basis, the ARM chips were as efficient as Intel x86 chips at the same clock frequency, but Intel was more efficient at the highest performance level, the researchers said.
Do Supercomputers Lead To Downtime?
As supercomputers grow more powerful, they’ll also become more susceptible to failure, thanks to the increased amount of built-in componentry. A few researchers at the recent SC12 conference, held last week in Salt Lake City, offered possible solutions to this growing problem.
Today’s high-performance computing (HPC) systems can have 100,000 nodes or more — with each node built from multiple components of memory, processors, buses and other circuitry. Statistically speaking, all these components will fail at some point, and they halt operations when they do so, said David Fiala, a Ph.D student at the North Carolina State University, during a talk at SC12.
The problem is not a new one, of course. When Lawrence Livermore National Laboratory’s 600-node ASCI (Accelerated Strategic Computing Initiative) White supercomputer went online in 2001, it had a mean time between failures (MTBF) of only five hours, thanks in part to component failures. Later tuning efforts had improved ASCI White’s MTBF to 55 hours, Fiala said.
But as the number of supercomputer nodes grows, so will the problem. “Something has to be done about this. It will get worse as we move to exascale,” Fiala said, referring to how supercomputers of the next decade are expected to have 10 times the computational power that today’s models do.
Today’s techniques for dealing with system failure may not scale very well, Fiala said. He cited checkpointing, in which a running program is temporarily halted and its state is saved to disk. Should the program then crash, the system is able to restart the job from the last checkpoint.
The problem with checkpointing, according to Fiala, is that as the number of nodes grows, the amount of system overhead needed to do checkpointing grows as well — and grows at an exponential rate. On a 100,000-node supercomputer, for example, only about 35 percent of the activity will be involved in conducting work. The rest will be taken up by checkpointing and — should a system fail — recovery operations, Fiala estimated.
Because of all the additional hardware needed for exascale systems, which could be built from a million or more components, system reliability will have to be improved by 100 times in order to keep to the same MTBF that today’s supercomputers enjoy, Fiala said.
Fiala presented technology that he and fellow researchers developed that may help improve reliability. The technology addresses the problem of silent data corruption, when systems make undetected errors writing data to disk.
Skype Confirms Glitch

Skype, a division of Microsoft, confirmed on Monday that a bug in its software has led to instant messages being shared with unintended parties.
The company said it will provide an update to fix the problem in “the next few days.”
According to user reports, the unintended recipients have been connected to just one of the two users who exchanging messages. The problem could have harmful consequences. For example, two co-workers using Skype to exchange IMs (instant messages) could, as a result of the problem, share the message with another contact in one user’s address book — potentially a third co-worker being unfavorably described in their IM exchange.
According to Skype, the problem only arises in “rare circumstances.”
The issue first came to light last week in Skype’s user forums. It seems to stem from the update issued by the voice, video and text messaging service in June.
IMs To Overtake Emails In Workplace
Comments Off on IMs To Overtake Emails In Workplace
Many CIOs predict that real-time communication technologies, such as instant messaging, SharePoint, Chatter and Yammer will outpace traditional email in the workplace in the next five years.
That’s the conclusion of a Robert Half Technology survey of more than 1,400 CIOs at U.S. companies with more than 100 employees. The survey was published last month.
More than half (54%) of the CIOs polled said real-time workplace communication tools will surpass traditional email in popularity within five years. The prediction was a bit lukewarm, however: 13% of the respondents said real-time messages will be “much more popular” than email, while 41% said they’ll be “somewhat more popular.”
Robert Half Technology, an IT staffing firm, said a transition to real-time tools could yield workplace benefits, potentially making it easier to work as a team, solve problems, share ideas and manage documents.

Comments Off on Free Mobile To Mobile Calling From AT&T
In what could be construed as attempt to curb potential subscriber loss due to Verizon’s impending iPhone, AT&T rolled out a mobile calling plan Wednesday that allows unlimited free voice calls to any wireless network in the U.S.
However, to be eligible for the new plan, Unlimited Mobile to Any Mobile, customers must still enroll in one of five qualifying mobile voice plans that charge for mobile calls to or from a landline phone.
Calling plans range from $39.99 a month to $109.99 a month, in addition to an unlimited messaging plan for $20 a month per individual or $30 a month per family…. Read More…..
