Comments Off on Is Lenovo Eyeing Blackberry?
Lenovo reportedly has joined the list of possible Blackberry buyers, with the firm reportedly having approached the struggling Canadian phone maker.
The Wall Street Journal reported that Lenovo, despite previously denying that it was mulling a Blackberry buy (paywalled), has been given the thumbs up to cast an eye over the Canadian company’s books before making it a possible offer.
If reports are to be believed, Lenovo has joined a list of possible buyers that includes Intel, Cisco, SAP, Google, Samsung and LG.
Specific details of Lenovo’s possible acquisition are yet to be revealed, but as a newcomer to the smartphone market Lenovo recently admitted that it is selling more smartphones than tablets and PCs in China, despite being one of the only PC makers to continue showing sales growth.
However, Lenovo’s smartphone portfolio is yet to appear the UK, and the firm hasn’t seen much success outside China. However, picking up Blackberry could help Lenovo enter the global smartphone market, and the firm could be looking to take over from Blackberry as a phone maker focused on business professionals.
Lenovo might have a hard time closing a buyout deal for Blackberry, though. Rumours about a takeover have already led to speculation that such a buyout would struggle to get approval from the US and Canada, due to the company’s Chinese ownership and the fact that Blackberry does business with sensitive parts of both governments.
Blackberry didn’t comment on a possible Lenovo buyout, but instead put out its usual vague statement. A company spokesperson said, “The special committee, with the assistance of Blackberry’s independent financial and legal advisors, is conducting a robust and thorough review of strategic alternatives.”
Lenovo declined to comment on the report.
Stanford Develops Carbon Nanotubes
Researchers at Stanford University have demonstrated the first functional computer constructed using only carbon nanotube transistors.
Scientists have been experimenting with transistors based on carbon nanotubes, or CNTs, as substitutes for silicon transistors, which may soon hit their physical limits.
The rudimentary CNT computer is said to run a simple operating system capable of multitasking, according to a synopsis of an article published in the journal Nature.
Made of 178 transistors, each containing between 10 and 200 carbon nanotubes, the computer can do four tasks summarized as instruction fetch, data fetch, arithmetic operation and write-back, and run two different programs concurrently.
The research team was led by Stanford professors Subhasish Mitra and H.S. Philip Wong.
“People have been talking about a new era of carbon nanotube electronics moving beyond silicon,” Mitra said in a statement. “But there have been few demonstrations of complete digital systems using [the] technology. Here is the proof.”
IBM last October said its scientists had placed more than 10,000 transistors made of nano-size tubes of carbon on a single chip. Previous efforts had yielded chips with just a few hundred carbon nanotubes.

Comments Off on Banks Join Instant Chat
Goldman Sachs Group Inc, JPMorgan Chase & Co and six other financial institutions have agreed to join a new instant messaging network from Markit and Thomson Reuters Corp to connect disparate messaging systems.
The network, called Markit Collaboration Services, launched on Monday and allows members to chat with one another regardless of the proprietary messaging technology that each firm uses.
This open platform differs Bloomberg LP’s messaging system, which is a closed network only for users of Bloomberg terminals.
Bloomberg messaging is the most popular form of chat on Wall Street, and often cited as one of the reasons banks are willing to pay around $20,000 a year for a subscription to a Bloomberg terminal.
Markit and Thomson Reuters said they hoped their open messaging network will attract banks that want to chat with their clients or other financial institutions but cannot currently do so because they are on different messaging systems.
The other banks that have joined the new network are Deutsche Bank, Bank of America Merrill Lynch, Barclays, Citigroup, Credit Suisse and Morgan Stanley, according to a statement from Markit.
The banks collectively employ more than 1 million people worldwide, though it was not immediately clear how many individuals will use the new Markit service.
David Craig, president of Thomson Reuters’ Financial & Risk division, said one of the challenges facing banks is that their messaging systems do not always talk to one another. “That creates costs and complexity,” he said.
Markit and Thomson Reuters said the messages on the new network are encrypted, and the system does not store them.
Representatives from Bank of America, Deutsche Bank, Goldman Sachs and Morgan Stanley were not immediately available to comment on the new messaging system. Representatives from Barclays, Citi, Credit Suisse and JPMorgan also declined to comment.
More OEM’s Seeking nVidia
As expected and announced, Zotac has now “joined the mobile gaming revolution” with the new Tegra Note 7 tablet and will be one of a handful of Nvidia partners that will sell it in both Europe and Asia-Pacific region for US $199.
In case you missed it yesterday when it was officially unveiled by Nvidia, the Nvidia Tegra Note 7 is based around a 7-inch 1280×800 IPS display and powered by Nvidia’s own Tegra 4 SoC with quad-core Cortex-A15 CPU and 72-core Geforce GPU paired up with 1GB of memory. It also packs some neat features exclusive to Nvidia, including a stylus with Nvidia DirectStylus technology as well as the 5-megapixel rear main camera backed by Chimera computational photography architecture revealed earlier by Nvidia. The camera will have support for both HDR as well as slow-motion video.
Unfortunately, Zotac did not announce the precise launch date so we are still stuck with Nvidia’s October time-frame and we are still to see the price of the new Tegra Note 7 in Europe.
Are More Firms Moving To Tegra 4?
A curious rumor is coming out of Taiwan this morning. Nvidia is reportedly seeing more Tegra 4 orders, boosted by the Xiaomi Mi3 smartphone, Surface RT 2 and new tablets from Asus, Toshiba and HP. The source is Digitimes, or its moles in the “upstream supply chain” to be specific. Specific is not the word usually associated with such sources and we have no specific numbers to report.
However, while Nvidia is seeing a bit more interest for Tegra 4 it simply has no high-volume design wins and shipments will remain low until it is eventually phased out in favour of the Tegra 5. We wrote about Nvidia’s Tegra 4 volume woes last month, here.
The Tegra 4 still has just a handful of design wins and the fact that most of them are high-end tablets is not encouraging at all. Not much has changed since our previous report, although Nvidia did manage to land a single smartphone design win, albeit not a major one.
We still believe Tegra 4 shipments will be modest at best and new Android tablet design wins will not help much. Neither will the Shield and Tegra Note tablets.
MIT Develops Inflatable Antenna

Comments Off on MIT Develops Inflatable Antenna
Satellites the size of shoe boxes, which are expected to one day allow researchers to explore space more efficiently, will soon have greater range.
MIT researchers have built and tested an inflatable antenna that can fold into such a satellite, then inflate in orbit to enable long range communications — from seven times the distance possible today.
The technology will let the small satellites, called CubeSats, move further into space and send valuable information to scientists back on earth.
“With this antenna, you could transmit from the moon, and even farther than that,” said Alessandra Babuscia, a researcher on the inflatable antenna team at MIT, in a statement. “This antenna is one of the cheapest and most economical solutions to the problem of communication. But all this research builds a set of options to allow the spacecraft … to fly in deep space.”
The MIT effort comes as engineers at the University of Michigan work on ways to propel such small spacecraft into interplanetary space. The team is building a plasma thruster that could fit in a 10-centimeter space and push a small satellite-bearing spacecraft into deep space.
The university researchers using superheated plasma that would push through a magnetic field to propel a CubeSat.
The MIT researchers are seeking to solve the communications problems and enable far-afield CubeSats to send data to and receive instructions from Earth.
The CubeSat devices cannot support radio dishes that are used today to let spacecraft communicate when far from Earth’s orbit.
The inflatable antennas significantly amplifies radio signals, allowing a CubeSat to transmit data back to Earth at a higher rate, according to the university.
MIT engineers have built two prototype antennae, each a meter wide, out of Mylar, which is a polyester film known for its strength and use as an electric insulator. One antenna was a cone shape, while the other looks more like a cylinder when inflated. Each fits into a 10-cubic-centimeter space within a CubeSat.
Each prototype contains a few grams of benzoic acid, which can be converted to a gas to inflate the antenna, MIT noted.
In testing, the cylindrical antenna performed “slightly better” than the cone shaped device, transmitting data 10 times faster, and seven times farther than existing CubeSat antennae.
Developers Hack Dropbox
Two developers have penetrated Dropbox’s security, even intercepting SSL data from its servers and bypassing the cloud storage provider’s two-factor authentication, according to a paper they published at USENIX 2013.
“These techniques are generic enough and we believe would aid in future software development, testing and security research,” the paper says in its abstract.
Dropbox, which claims more than 100 million users upload more than a billion files daily, said the research didn’t actually represent a vulnerability in its servers.
“We appreciate the contributions of these researchers and everyone who helps keep Dropbox safe,” a spokesperson said in an email to Computerworld. “In the case outlined here, the user’s computer would first need to have been compromised in such a way that it would leave the entire computer, not just the user’s Dropbox, open to attacks across the board.”
The two developers, Dhiru Kholia, with the Openwall open source project , and Przemyslaw Wegrzyn, with CodePainters, said they reverse-engineered Dropbox, an application written in Python.
“Our work reveals the internal API used by Dropbox client and makes it straightforward to write a portable open-source Dropbox client,” the paper states. “Additionally, we show how to bypass Dropbox’s two-factor authentication and gain access to users’ data.”
The paper presents “new and generic techniques to reverse engineer frozen Python applications, which are not limited to just the Dropbox world,” the developers wrote.
The researchers described in detail how they were able to unpack, decrypt and decompile Dropbox from scratch. And, once someone has de-compiled its source code, how “it is possible to study how Dropbox works in detail.
“We describe a method to bypass Dropbox’s two-factor authentication and hijack Dropbox accounts. Additionally, generic techniques to intercept SSL data using code injection techniques and monkey patching are presented,” the developers wrote in the paper.
The process they used included various code injection techniques and monkey-patching to intercept SSL data in a Dropbox client. They also used the techniques successfully to snoop on SSL data in other commercial products as well, they said.
The developers are hoping their white hat hacking prompts Dropbox to open source its platform so that it is no longer a “black box.”
Is The Tesla Hackable?
It’s the curse of the connected car once it’s linked to the Internet, it’s, well, on the Internet. In the case of the Tesla Model S, this means that mischievous hackers could, in theory, control some functions of the vehicle and even snoop without the owner’s knowledge.
Tesla offers Android and iPhone apps for Model S owners, which can be used to check the vehicle’s battery, track its location and status, and tweak several other settings, like climate control and the sunroof. It can also be used to unlock the doors on the Model S.
Dell senior engineer George Reese says the REST API used by Tesla to provide access for Android and iPhone apps has several fairly serious security flaws, which could offer a way in for unscrupulous hackers.
According to an article written by Reese for O’Reilly, Tesla appears to have broken from accepted best practice when designing the API for the Model S.
“It’s flawed in a way that makes no sense. Tesla ignored most conventions around API authentication and wrote their own. As much as I talk about the downsides to OAuth (a standard for authenticating consumers of REST APIs–Twitter uses it), this scenario is one that screams for its use,” he wrote.
However, Reese notes, this is merely a potential attack vector, not one that could be immediately exploited. That said, a compromised website particularly one designed to provide “value-added services” via the API to Tesla drivers could prove highly damaging.
“I can … honk their horns, flash their lights, and open and close the sunroof. While none of this is catastrophic, it can certainly be surprising and distracting while someone is driving,” Reese wrote.
Automotive hacking has been posited by experts for some time, and several presentations at this year’s Defcon detailed fairly comprehensive methods of compromising some models.
U.S. Cloud Vendors Hurt By NSA
Edward Snowden’s public unveiling of the National Security Agency’s Prism surveillance program could cause U.S. providers of cloud-based services to lose 10% to 20% of the foreign market — a slice of business valued at up to $35 billion.
A new report from the Information Technology & Innovation Foundation (ITIF) concludes that European cloud computing companies, in particular, might successfully exploit users’ fears about the secret data collection program to challenge U.S. leadership in the hosted services business.
Daniel Castro, author of the report, acknowledges that the conclusions are based, so far, on thin data, but nonetheless argues that the risks to U.S. cloud vendors are real.
Indeed, a month prior, the Cloud Security Alliance reported that in a survey of 207 officials of non-U.S. companies, 10% of the respondents said that they had canceled contracts with U.S. service providers after Snowden’s leak of NSA Prism documents earlier this year.
“If U.S. companies lose market share in the short term, it will have long-term implications on their competitive advantage in this new industry,” said Castro in the ITIF report. “Rival countries have noted this opportunity and will try to exploit it.”
To counter such efforts, the U.S. must challenge overstated claims about the program by foreign companies and governments, said Jason Weinstein, a partner in the Washington office of law firm Steptoe & Johnson and a former federal prosecutor and deputy assistant attorney general specializing in computer crime.
“There are a lot of reasons to be concerned about just how significant those consequences will be,” Weinstein said. “The effort by European governments and European cloud providers to cloud the truth about data protection in the U.S. was going on well before anyone knew who Edward Snowden was. It just picked up new momentum once the Prism disclosures came out.”
Weinstein contends that European countries have fewer data protection rules than the U.S.
For example, he said that in the U.K. and France, a wiretap to get content can be issued by a government official without court authority, but that can’t happen in the U.S.
“U.S. providers have done nothing other than comply with their legal obligations,” he said. But because of Snowden’s leaks, “they are facing potentially significant economic consequences.”
Gartner analyst Ed Anderson said his firm has yet to see any revenue impact on cloud providers since the Prism disclosures, but added, “I don’t think Prism does U.S. providers any favors, that’s for sure.”
Nonetheless, Anderson added, “I think the reality is [the controversy] is likely to die down over time, and we expect adoption to probably continue on the path that it has been on.”
One reason why U.S. providers may not suffer is because “the alternatives aren’t great if you are a European company looking for a cloud service,” he said.
Will The Tegra Processor Pay Off?
Last year Nvidia’s Tegra gamble seemed to be paying off nicely, but the insanely competitive SoC market moves fast and all it takes for things to go badly wrong is one botched generation. The Tegra 4 was late to the party and Nvidia eventually ended up with a big and relatively powerful chip that nobody wanted.
In its latest earnings call Nvidia made it clear that revenues from Tegra are expected to decline $200 to $300 million this year from about $750 million last year. Even this seems like a relatively optimistic forecast. Tegra 3 ended up in quite a few high-volume products, such as the Nexus 7, HTC One X, LG Optimus X4 and a bunch of other phones and tablets. On paper, Tegra 4 will end up with a similar number of design wins, maybe even more, but nearly all of them are low-volume products.
At the moment there are only a handful of Tegra 4 products out there. These include HP’s Slatebook 10, Toshiba eXcite Pro and eXcite Write tablets and Nvidia’s own Shield console. Nvidia’s 7-inch Tegra Tab is also on the way, along with the Surface RT 2. Some Chinese vendors like ZTE are also expected to roll out a Tegra 4 phone here and there, but the chip won’t end up in any big brand phones.
Nvidia does not release any Tegra unit shipment info, so we can only guess how many Tegra 3 and Tegra 4 chips are out there, but it doesn’t take much to realise Tegra 4 is a flop. Shipments of the original Nexus 7, powered by the Tegra 3, are estimated just north of six million units. Surface RT shipments were abysmal. Earlier this year analysts put the figure at just 900,000 units after a full quarter of sales. Microsoft eventually took a massive write-down on its Surface RT stock. LG and HTC didn’t reveal any shipment figures for the Optimus 4X and HTC One X, either. HTC shipped about 40 million phones last year, while LG managed about 27 million. We can’t even begin to estimate how many of them were flagship products powered by Tegra, but the number was clearly in the millions.
This time around Nvidia can’t count on strong smartphone sales, let alone the Nexus 7 and Surface RT. Even if it scores high-end tablet design wins, the truth is that high-end Android tablets just aren’t selling well. Nvidia needed high-volume design wins and Android tablets just won’t do the trick. Qualcomm is in the new Nexus 7 and the HTC One. Back in May analysts reported that HTC One sales hit the 5 million mark in the first two months of sales, although shipments have slowed down since then. Millions of Snapdragons found a home in the HTC One and millions more will end up in the new Nexus 7.
Nvidia’s talk of a $200 to $300 million hit this year doesn’t exactly paint the full picture. Tegra 3 shipments in the first two quarters of 2013 were modest, but relatively good. However, nothing took its place and the true extent of the Tegra 4 flop will only become visible in the first quarter of 2014 and beyond. The big hope is that the Tegra 4i and Tegra 5 will start to come online by then, so the numbers for the full year won’t be as terrible, but it is abundantly clear that Nvidia cannot afford another Tegra 4.
As for Nvidia’s Tegra Tab and Shield, they might do well. Nvidia knows a thing or two about hardware, but even if they prove successful, they just won’t be enough, at least not in this cycle.
