Africa To Lead Global Bandwidth Demand
Comments Off on Africa To Lead Global Bandwidth Demand
Africa’s demand for Internet access to the rest of the world will grow by an average of 51 percent every year until 2019, ahead of all other regions, according to a forecast by research company Telegeography.
Rapid economic growth and wider Internet use will drive the increase in demand, which will be met mostly by turning on unused capacity in existing cables, according to Telegeography analyst Erik Kreifeldt. Terrestrial links are in demand partly because much of Africa still relies on satellite, which is far more expensive per bit than wired broadband, he said.
Most Internet bandwidth between continents is provided by undersea cables built and financed by groups of service providers. From Africa, most of those links go to Europe. Other carriers pay to tap into those cables and link their customers to the Internet. In some parts of Africa, running cables from coastal areas to the interior is a challenge so satellite remains the major Internet source, Kreifeldt said.
The capacity of international cables landing on African shores is just a fraction of the bandwidth available between Europe, the U.S. and Asia. After seven years of the growth that Telegeography forecasts, from 2012 through 2019, Africa will have 17.2Tbps (bits per second) of links to the outside world. That’s up from just 957Gbps in 2012 but will still be only about one-quarter of the international capacity of Latin America and less than that of Canada, according to Telegeography.
The hunger for the Internet varies among African countries. Through 2019, bandwidth demand is expected to grow fastest in Angola, at 71 percent per year; Tanzania, at 68 percent; and Gabon, at 67 percent.
Many new cables have been built to Africa and around the continent in the past several years, giving service providers excess fiber capacity that can be turned on when needed, Kreifeldt said. As that fiber gets lit up and supply rises, prices should fall for enterprises and other users in African countries, he said. However, due to relative scarcity, a given amount of bandwidth between Africa and Europe costs about 10 times as much as the same size connection between Europe and North America, he said. Africa’s bandwidth gains aren’t expected to shrink that gap.
ATM Malware Found In Mexico
A malicious software program identified in ATMs in Mexico has been improved and translated into English, which suggests it may be used elsewhere, according to security vendor Symantec.
Two versions of the malware, called Ploutus, have been discovered, both of which are engineered to empty a certain type of ATM, which Symantec has not identified.
In contrast to most malware, Ploutus is installed the old-fashioned way — by inserting a CD boot disk into the innards of an ATM machine running Microsoft Windows. The installation method suggests that cybercriminals are targeting standalone ATMs where access is easier.
The first version of Ploutus displays a graphical user interface after the thief enters a numerical sequence on an ATM’s keypad, although the malware can be controlled by a keyboard, wrote Daniel Regalado, a Symantec malware analyst, on Oct. 11.
Ploutus is programmed for a specific ATM model since it assumes there is a maximum of four cassettes per dispenser in the ATM. It then calculates the amount of money that should be dispensed based on the number of bills. If any of the cassettes have less than the maximum number of 40 bills, it releases whatever is left, repeating that process until the ATM is empty.
Kevin Haley, director of Symantec Security Response, said in an interview earlier this month that the attackers have deep knowledge of the software and hardware of the particular ATM model.
“They clearly know how this machine worked,” he said.
The source code of Ploutus “contains Spanish function names and poor English grammar that suggests the malware may have been coded by Spanish-speaking developers,” Regalado wrote.
In a new blog post, Regalado wrote that the attackers made Ploutus more robust and translated it into English, indicating the same ATM software can be exploited in countries other than Mexico.
The “B” variant of Ploutus has some differences. It only accepts commands through the keypad but will display a window showing the money available in the machine along with a transaction log as it dispenses cash. An attacker cannot enter a specific number of bills, so Ploutus withdraws money from the cassette with the most available bills, Regalado wrote.
Symantec advised those with ATMs to change the BIOS boot order to only boot from the hard disk and not CDs, DVDs or USB sticks. The BIOS should also be password protected so the boot options can’t be changed, Regalado wrote.
LG Goes Self-Healing

Comments Off on LG Goes Self-Healing
LG is upping the ante in smartphone technology with a new handset that has a curved touchscreen, along with a special “self healing” technology that the company claims can prevent scratches on the phone’s casing.
The South Korean electronics vendor unveiled the new phone on Monday, calling it the LG G Flex. Digital renderings of the handset were leaked earlier this month. But in its Monday announcement the company offered further details on the phone, showing that it contains a few new technologies, along with its curved display.
The G Flex is the second phone to feature a curved display, the first coming from Samsung Electronics with its Galaxy Round handset. The top and bottom of the G Flex’s 6-inch screen are curved towards the user, while on the Samsung phone it is the sides that are curved towards the viewer.
This makes LG’s handset closer to the curve of a traditional fixed-line phone handset, a design choice LG said is optimized for the contours of a face. Users can more comfortably hold the phone to their mouth and ear, improving its voice and sound quality, according to LG.
The company also touted the design by stating that the phone offers an easier grip, and holds better in a person’s back pocket. In addition, LG said the curved screen gives an “IMAX-like” experience when viewing videos, allowing for a greater field of view.
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.
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.
IBM Goes Linux
IBM reportedly will invest $1bn in Linux and other open source technologies for its Power system servers.
The firm is expected to announce the news at the Linuxcon 2013 conference in New Orleans, pledging to spend $1bn over five years on Linux and related open source technologies.
The software technology will be used on IBM’s Power line of servers, which are based on the chip technology of the same name and used for running large scale systems in data centres.
Previously IBM Power systems have mostly run IBM’s proprietary AIX version of Unix, though some used in high performance computing (HPC) configurations have run Linux.
If true, this will make the second time IBM coughs up a $1bn investment in Linux. IBM gave the open source OS the same vote of confidence around 13 years ago.
According to the Wall Street Journal, IBM isn’t investing in Linux to convert its existing AIX customers, but instead Linux will help support data centre applications driving big data, cloud computing and analytics.
“We continue to take share in Unix, but it’s just not growing as fast as Linux,” said IBM VP of Power development Brad McCredie.
The $1bn is expected to go mainly for facilities and staffing to help Power system users move to Linux, with a new centre being opened in France especially to help manage that transition.
Full details are planned to be announced at Linuxcon later today.
Last month, IBM swallowed Israeli security firm Trusteer to boost its customers’ cyber defences with the company’s anti-hacking technology.
Announcing that it had signed a definitive agreement with Trusteer to create a security lab in Israel, IBM said it planned to focus on mobile and application security, counter-fraud and malware detection staffed by 200 Trusteer and IBM researchers.
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.
Dell Bets On Windows 8
Demand for Windows 8 may be still somewhat lukewarm, but Dell is maintaining its stance that it is the best operating system for business tablets and plans to roll out more Windows 8-based products later this year, according to a senior executive at the computer maker.
“Our Windows tablets are more secure and easier to manage than Android-based products and iOS-based products [because Windows is] on our tablets,” said Jeff Clarke, vice chairman and president of global operations at Dell. “And we are not going to change that.”
Windows-based devices accounted for just 4.5% of tablet sales in this year’s second quarter, according to research firm IDC. In comparison, Android-based devices had 62.6% of the tablet market and Apple’s iPad had 32.5%.
The slow adoption of Windows 8 tablets is partly due to their high prices, and to the operating system’s lack of mobile apps, analysts say. Windows 8 has also received mixed reviews, with some people citing its lack of a Start button in the desktop mode as a major problem.
But Dell expects demand for Windows 8 devices to pick up with the availability of Windows 8.1, which Microsoft will release in October.
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.”
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.
