Comments Off on HP To Support The iPad
Is your iPad out of warranty? Hewlett-Packard to the rescue.
HP updated its SmartFriend support service and will now troubleshoot problems with Windows, Android, Chrome OS, OS X and iOS products, according to a fact sheet describing the service.
“HP is expanding its HP SmartFriend service to provide 1:1 expert support for any brand of PC or tablet,” the company said. The plan previously supported PCs from HP and other vendors, as well as Macs.
Users can avail of the service to address general hardware, software and malware issues. HP says its agents can “remove viruses, improve PC performance, solve software errors, and connect devices to a wireless network with enhanced security.” The support is provided by phone or over the Internet, so don’t expect a technician to trot in and fix your iPad in person. But HP notes it can save you from driving to a store.
Unlike Best Buy’s Geek Squad service, HP’s service does not include hardware repairs. It can be tricky to change the battery or storage in tablets, so for iPads, the Genius Bars at Apple Stores may still be the best option for some repairs.
HP didn’t immediately comment on exactly what support it will provide for the iPad. HP printers offer wireless printing from iPads and iPhones. HP sells primarily Windows PCs and Android tablets, though on last Thursday it announced the Pavilion 14 laptop with Google’s Chrome OS.
While SmartFriend includes support for iOS devices, the service seems focused mainly on Windows products. Its technicians include “Microsoft Application Trainers, Microsoft Product Specialists, A+/MCP/MCSE Certified Professionals, Network Administrators and HTML Developers,” according to the fact sheet.
The service starts at US$9.99 per month and users can sign up for a pre-paid, monthly or yearly support plan. A “Complete Plan” supports two devices, while a “Family Plan” supports up to four devices.
Samsung’s Eight-core Chip Goes Hacking
Comments Off on Samsung’s Eight-core Chip Goes Hacking
A Samsung eight-core chip used in some Galaxy S4 mobile devices is now available for hackers to play with on a developer board from South Korea-based Hardkernel.
Hardkernel’s Odroid XU board has incorporated Samsung’s eight-core Exynos 5 Octa 5410 chip, which is based on ARM’s latest processor designs. Samsung recently announced a new eight-core chip, the Exynos 5 Octa 5420, which packs faster graphics and application processing than the 5410. The 5420 has not yet been shipped yet, however.
The Odroid board is priced at $149 through Aug. 31, after which it will be offered for $169. Samsung for many months has said that a board with an eight-core chip would be released, and has shown prototype developer boards at conferences.
Odroid-XU will provide developers an opportunity to write programs tuned for Samsung’s octa-core chip, which has been a source of controversy. Analysts have said the eight-core design is overkill for small devices like smartphones and tablets, which need long battery life.
The eight-core chip design also takes up a lot of space, which prevented Samsung from putting LTE radios inside some Galaxy S4 models. Qualcomm, which hesitantly moved from the dual core to the quad-core design on its Snapdragon chips, on Friday criticized eight-core chips, calling the idea “dumb.”
Despite the criticism, the board will give developers a first true glimpse of, and an opportunity to write and test applications for, ARM’s Big.Little design. The design combines high-power cores for demanding applications with low-power cores for mundane tasks like texting and calling.
Samsung’s iteration of Big.Little in the Exynos 5 Octa 5410 chip combines four processors based on ARM’s latest Cortex-A15 processor design, which incorporates four low-power Cortex-A7 CPUs. The Cortex-A15 is ARM’s latest processor design and succeeds the previous Cortex-A9 core, which was used in popular smartphones like Apple’s iPhone and the Galaxy S3. Samsung said the eight-core chip provides a balance of power and performance, with the high-power cores kicking in only when necessary.
The board has an Imagination Technologies PowerVR SGX544MP3 graphics processor, 2GB of low-power DDR3 DRAM, two USB 3.0 ports and four USB 2.0 ports. Other features include Wi-Fi, Ethernet and optional Bluetooth. Google’s Android 4.2 operating system is preloaded, and support for other Linux distributions like Ubuntu is expected soon. The board has already been benchmarked on Ubuntu 13.04.
Is This A Mobile First World?

Comments Off on Is This A Mobile First World?
Judging from the number of people engrossed in activities with their smartphones on the sidewalk, in their cars and in public places, mobile seems to have stolen our attention away from the wired Internet and traditional TV.
However, there is a ways to go before mobile platforms become the primary place where consumers turn for entertainment and getting things done, players at CTIA Wireless trade show said.
Nokia Siemens Networks announced new capabilities in its network software to make video streams run more smoothly over mobile networks. Among other things, the enhancements can reduce video stalling by 90 percent, according to the company. But even Sandro Tavares, head of marketing for NSN’s Mobile Core business, sees “mobile-first” viewing habits as part of the future.
“Now that the networks are providing a better capacity, a better experience with mobile broadband, mobile-first will come,” Tavares said. “Because the experiences they have with the devices are so good, these devices … start to be their preferred screen, their first screen.
“This is a trend, and this is something that will not change,” Tavares said. But he thinks it’s too early to build networks assuming consumers will turn to tablets and phones as their primary sources of entertainment. “Do you have to be prepared for mobile-first now? Probably not. You have to be able to keep the pace.”
For AT&T, mobile-first is a top priority for its own internal apps, ensuring employees can do their jobs wherever they are, said Kris Rinne, the carrier’s senior vice president of network technologies. But to make it possible over the network, a range of new technologies and relationships may have to come together, she said.
For example, giving the best possible performance for streaming video and other uses of mobile may require steering traffic to the right network if both cellular and Wi-Fi are available. AT&T is developing an “intelligent network selection” capability to do this, Rinne said. When AT&T starts to deliver voice over LTE, it will stay on the cellular network — at least in the early days — because the carrier has more control over quality of service on that system, she said.
Other issues raised by mobile-first include security of packets going over the air and rights for content that subscribers are consuming primarily on mobile devices instead of through TV and other traditional channels, Rinne said.
Microsoft Looks Into Smart Watches

Comments Off on Microsoft Looks Into Smart Watches
Microsoft is developing designs for a touch-enabled smart watch, joining a number of other large competitors like Samsung Electronics and Apple who are said to be working on similar devices, according to a recent report.
Executives at suppliers to Microsoft told The Wall Street Journal that the company was sourcing components for the prototype of what could potentially be a “watch-style device.”
Microsoft has, for example, requested 1.5-inch displays from component makers for the prototype, an executive at a component supplier told the newspaper. It is unclear whether the company will decide to go ahead with the watch, the newspaper added.
Microsoft could not be immediately reached for comment.
A large number of vendors are looking at new product categories beyond smartphones and tablets.
This isn’t the first time, however, that Microsoft may be looking at watches as a product. It launched a smart wrist watch around a concept called Smart Personal Object Technology it unveiled in 2002, but withdrew it after a lackluster performance.
The Redmond, Wash., company is seeing its key PC market under threat from smartphones and tablets, and the failure of its new Windows 8 operating system to boost sales significantly. IDC said last week that first quarter PC shipments totaled 76.3 million units, down 13.9% compared to the same quarter last year. (The decline was worse than the 7.7% previously forecast by the analyst firm, and the market could be headed into further contraction, the research firm added.
Will HP Be Broken Up?
HP has been urged by investment bank UBS to break itself up in order to boost its share price.
After years of mismanagement, HP’s stock price is far lower than it was during the heady dotcom bubble days when it pulled off one of the biggest mergers in recent years by buying Compaq. Now the firm’s stock price languishes around the $14 mark, a figure that could top $20 if HP were to break itself up, according to UBS.
UBS analysts including Steven Milunovich reported the firm could “realise greater value” by splitting itself up. The analysts added that each separate division of HP is big enough to stand on its own, claiming, “HP’s units are not minnows but rather they are whales packed into the same pond.”
HP spokesman Michael Thacker claimed the firm’s customers want a big HP, effectively allowing them to have one supplier for their IT needs, a message the firm has been playing up for a number of years now. Thacker said, “No matter how you look at it we are confident that HP is stronger together than apart. The company’s operations across business units are deeply integrated and our customers have told us that they want One HP.”
Does 4G Pose A Security Threat?
Could 4G Networks give way for more high-risk mobile security implications; Symantec is warning of such a wave of threats.
“We could see a move to the sort of threats that we already see on the wireless and fixed connected network,” John said. “Malware that you usually have on fixed networks, like botnets.
“There aren’t many botnets on mobile devices because the bandwidth’s not there to support it, once you go on to 4G [hackers] could start infecting systems.”
To ensure that enterprises avoid these these security threats, John advised that businesses need to be on their toes more than ever, look closely at everything that’s coming into the network, and not trust anything.
“Companies need to make sure that where traditionally it’s been a firewall with a perimeter with everything in a timeline environment,” John said. “What they need to look at is ‘what are my employees doing’, ‘what information is being shared’ and ‘how do we ensure our information is being protected no matter where it may be’, whether its mobile device, across networks or sitting in a cloud service.”
“This is a change we are going through, but 4G is going to push the need for that change even more so,” she added.
According to John, 4G will also be detrimental to businesses in the way it will add a greater burden for them to ensure that cloud services and mobility – what she calls “two of the biggest security challenges for enterprises and their employees” – are up to scratch.
U.S. Takes Back Supercomputing Crown
The U.S., once again, is home to the world’s most powerful supercomputer after being kicked off the list by China two years ago and then again by Japan last year.
The top computer, an IBM system at the Department of Energy’s Lawrence Livermore National Laboratory, is capable of 16.32 sustained petaflops, according to the Top 500 list, a global, twice a year ranking, released Monday.
This system, named Sequoia, has more than 1.57 million compute cores and relies on architecture and parallelism, and not Moore’s Law, to achieve its speeds.
“We’re at the point where the processors themselves aren’t really getting any faster,” said Michael Papka, Argonne National Laboratory deputy associate director for computing, environment and life sciences.
The Argonne lab installed a similar IBM system, which ranks third on the new Top 500 list. “Moore’s Law is generally slowing down and we’re doing it (getting faster speeds) by parallelism,” Papka said.
U.S. high performance computing technology dominates the world market. IBM systems claimed five of the top ten spots in the list, and 213 systems out the 500.
Hewlett-Packard is number two, with 141 systems on the list. Nearly 75% of the systems on this list run Intel processors, and 13% use AMD chips.
Android Apps To Run On Windows
Software firm Bluestacks is on a mission to close the gap between Microsoft’s Windows and Google’s Android OS with its App Player application, which was released in beta earlier this week.
App Player is an emulator that allows Android applications to run on Windows 7, Vista and XP OSes. Users can install the software in Windows and then run around 450,000 Android applications, including Angry Birds and Fruit Ninja, the company said in a statement.
Beyond PCs, the App Player could also allow Windows tablets such as Hewlett-Packard’s Slate 2 and Dell’s Latitude ST to run Android applications. Bluestacks made headlines at last year’s Computex trade show in Taipei when Advanced Micro Devices showed off an x86 tablet with Android running on top of the Windows 7 software stack. Android applications are mostly written for the ARM instruction set, but the x86 tablet was able to switch between Android and Windows without any problems.
The emulator has new Layercake technology, which exploits hardware accelerators to improve the performance of Android games in Windows. The layer was not included in the previous Bluestacks alpha version. Android applications typically use hardware accelerators found in ARM’s Mali, Nvidia’s Tegra or Imagination Technologies’ PowerVR graphics cores, but Layercake is able to take advantage of hardware accelerators from companies like AMD found in x86 chips.

Comments Off on at&t iPhone 4S Has Fastest Speeds
A study measuring the performance of the iPhone 4S on the three major U.S. wireless carriers found AT&T to be the best in Web browsing and data downloads and uploads when compared to Apple’s latest smartphone on either the Verizon Wireless or Sprint networks.
iPhone newcomer Sprint was found to be superior with its iPhone 4S for network voice quality on the uplink (when the user is speaking), but Sprint was also about five times slower in Web browsing and data downloads than AT&T, according to the study released Friday by Metrico Wireless, a mobile performance measurement company. Verizon finished in the middle on those data tests, but trailed the other two carriers in voice quality.
Metrico measured five performance factors shortly after the iPhone 4S was launched on all three carriers in October: whether calls could be connected and held; voice quality; data performance; Web browsing by page load speeds and video performance.

China’s Supercomputer Uses Homegrown Chips
Comments Off on China’s Supercomputer Uses Homegrown Chips
China has built its latest supercomputer based entirely on homegrown microprocessors, a major move towards breaking the country’s reliance on Western technology for high-performance computing.
China’s National Supercomputer Center in Jinan debuted the computer last Thursday, according to a report from the country’s state-run press. The supercomputer uses 8,704 “Shenwei 1600″ microprocessors, which were developed by a design center in Shanghai, called the National High Performance Integrated Circuit Design Center.
Details of the microprocessors and the design center were not immediately available.
The supercomputer has a theoretical peak speed of 1.07 petaflops (quadrillion floating-point calculations per second), and a sustained performance of 0.79 petaflops when measured with the Linpack benchmark. This could place it at number 13 in the world’s top 500 supercomputing list. Photos of the chips used and the supercomputer’s data center can be found here.
China’s Shandong Academy of Sciences built the computer. Officials of the academy could not be immediately reached for comment on Monday.
A report from The New York Times said the supercomputer’s name in English was the Sunway BlueLight MPP.
