PayPal Extend Bug Bounty
PayPal is expanding its bug bounty program to individuals aged 14 and older, a move intended to reward younger researchers who are technically ineligible to hold full-fledged PayPal accounts.
PayPal’s program, which is a year old this month, only applied to those 18 years and older. Under the old rule, participants in the program were required to hold valid accounts, which excluded minors, said Gus Anagnos, PayPal’s director of information security.
In May, 17-year-old Robert Kugler, a student in Germany, said he’d been denied a reward for finding a vulnerability. PayPal said the bug had already been found by two other researchers, which would have made Kugler ineligible for bounty.
In an apparent miscommunication, Kugler said he was initially told he was too young rather than the bug had already been discovered. Nonetheless, PayPal said it would look to bring younger people into its program, which pays upwards of $10,000 for remote code execution bugs on its websites.
Those who are under 18 years old can receive a bug bounty payment through a PayPal student account, an arrangement where a minor can receive payments via their parent’s account, Anagnos said.
Anagnos said other terms and conditions have been modified to make its program more transparent, such as clarifying which PayPal subsidiaries and partner sites qualify for the program.
PayPal pays much less for vulnerabilities on partner websites, which have a URL form of “www.paypal-__.com.” A remote execution bug found on that kind of site garners only $1,500 rather than up to $10,000 on the company’s main sites.
Like other bug bounty programs run by companies such as Microsoft and Google, PayPal will publicly recognize researchers on its website with a “Wall of Fame” for the top 10 researchers in a quarter. Another “honorable mention” page lists anyone who submitted a valid bug for the quarter.
Eusebiu Blindu, a testing consultant from Romania, was one of the researchers listed on the Wall of Fame for the first quarter of this year.
“I think Paypal is the best bug bounty program, and I am glad I participated in it from the first days of its launching,” he wrote on his blog.
Will 3D Printing Take Off?

Comments Off on Will 3D Printing Take Off?
The use of cheaper 3D printing is set to take off when a batch of patents expires in 2014.
Duann Scott, design evangelist at 3D printing company Shapeways said that in February 2014, key patents that currently prevent competition in the market for the most advanced and functional 3D printers will expire. The important patent is one which covers “laser sintering” which is the lowest-cost 3D printing technology. Because of its high resolution in all three dimensions, laser sintering can produce goods that can be sold as finished products.
At the moment it is only possible to buy expensive 3D laser sintering printers, which can cost tens of thousands of dollars each. But once the key patents on 3D printing via laser sintering expire, we could see huge drop in the price of these devices, says Scott.
Key patents expired on a more primitive form of 3D printing, known as fused deposition modelling resulted in an explosion of open-source FDM printers that eventually led to iconic home and hobbyist 3D printer manufacturer Makerbot. When the patents on FDM expired the cost of such printers fell as little as $300. Scott thinks that the same thing will happen with laser deposition 3D printers.
Microsoft Drops The Surface
Microsoft has dropped the prices on its Surface RT tablets by as much as 30%, with the entry-level 32GB model selling for $349.
The 64GB Surface RT was also discounted by $150, and now sells for $449, or 25% off its former price.
When Microsoft launched the tablet, it sold the 32GB device for $499 and the 64GB configuration for $599.
Microsoft started selling the Surface RT at the lower prices Sunday, as did some of its U.S. retail partners, including Best Buy and Staples. On its website, Staples noted that the discounted prices are valid until July 20, and only while supplies last.
Microsoft’s website, however, listed no caveats, hinting that the lower prices might be permanent or at least will be honored for longer than one week.
The prices are another attempt by Microsoft to clear its existing inventory in preparation for a second-generation line of Windows RT devices. Previously, Microsoft had launched multiple deals to rid itself of the poor-selling tablet, most recently in June when it slashed prices by 60% in a bid to get universities and K-12 schools to buy the device.
Earlier, it kicked off a buy-a-Surface-RT-get-a-free-cover deal that ran until June 30. And at several conferences, including June’s TechEd North America and this month’s Microsoft Partner Conference, the company sold attendees a 64GB Surface RT for $100, 83% off list price.
Today’s sale prices were nearly Microsoft’s cost, which according to estimates of the tablet’s component prices, runs the company at least $284 for the 32GB Surface RT.
Microsoft has not abandoned Windows RT, the pared-down operating system that powers the Surface RT, but virtually every third-party OEM has either pointedly ignored the OS or publicly announced that they would not support it with devices of their own. Instead, the OEMs have flocked to Windows 8 Pro, even though some analysts question the value of touch devices on a platform whose biggest selling point is legacy software that doesn’t support touch.
Microsoft has not revealed sales figures for the Surface line — which also includes the Surface Pro, powered by Windows 8 Pro — but estimates by research firms like IDC have been lackluster.
MS Office Demand Fizzles
After a promising start, downloads of Microsoft’s free Office for the iPhone quickly nosedived, as the latest data from a mobile app analytics company showed.
But at least 200,000 copies of the small suite — iPhone versions of Word, Excel and PowerPoint — were downloaded in the first six days.
Distimo, a Dutch firm that tracks app store market data for several platforms, including Apple’s iOS, Google’s Android, and Microsoft’s Windows 8 and Windows Phone, said Office Mobile for the iPhone debuted in the No. 10 spot on June 15, the day after Microsoft launched the free app.
That was Office Mobile’s peak: On June 16, Office Mobile slipped to the No. 19 position among all free iPhone apps, then continued to slide throughout the week of June 17-23, starting that seven-day stretch at No. 36, falling to No. 86 by Friday, June 21, and ending at No. 299 on June 23.
From June 24 to July 6, Office Mobile was not on Distimo’s leaderboard, which lists only the top 400 downloaded apps.
The number of downloads of Office Mobile for iPhone is unknown — Distimo requires a paid account to show developers the estimated downloads of their apps and those of competitors, and did not reply to questions Sunday — but the tally was probably significant.
According to Distimo, to place in the App Store’s No. 10 spot, an app must average 72,000 downloads daily. Office Mobile was ranked No. 10 on June 15. Apps ranked at No. 50 averaged 23,000 downloads daily: Office Mobile held position at No. 50 or lower for five consecutive days.
Those numbers implied that at least 200,000 copies of Office Mobile were downloaded in the six days between June 15 and June 20.
Likewise, the sharp decline of Office Mobile’s position in the App Store’s free list after just a week hints at a pent-up demand that was quickly satisfied.
Although rumors of Office on iOS had circulated since the iPad’s 2010 introduction, they heated up last November when reports claimed Microsoft would launch a mobile version of the suite this year and tie the software to Office 365. At the time, most analysts agreed that Office 365 was the smart move because it could boost interest in the subscription concept Microsoft has bet will result in more, and more regular, revenue from its Office cash cow.
Linking Office on iOS to Office 365 would also let Microsoft avoid the Apple “tax,” the 30% cut that Apple takes from all App Store sales.
Only Office 365 subscribers can use Office Mobile. Subscriptions range from the consumer-grade Office 365 Home Premium, which costs $100 annually, to several business plans that start at $150 per user per year and climb to $264 per user per year.
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.
Microsoft Raises Office Price
Microsoft has quietly increased prices of Office for the Mac as much as 17% and stopped selling multi-license packages of the application suite.
The move puts Office for Mac 2011 on the same pricing schedule as the new Office 2013 for Windows. The price increases and the disappearance of the multi-license bundles also makes Microsoft’s Office 365, a software-by-subscription deal the company has aggressively pushed, more competitive with traditional “perpetual” licenses.
It’s not clear when Microsoft raised prices. The oldest search engine cache Computerworld found with the new prices was Feb. 2, so the company boosted them before then, likely on Jan. 29, the day it launched Office 2013 and Office 365 Home Premium. Microsoft did not mention the changes to Office for Mac in its press releases that day, or otherwise publicize the move on its Mac-specific website.
The single-license Office for Mac Home & Student now costs $140, a 17% increase from the previous price of $120. Office for Mac Home & Business, an edition that adds the Outlook email client to Home & Student’s Excel, PowerPoint and Word, runs $220, or 10% higher than the older $200 price.
The new prices are identical to those of Office 2013 for Windows, as are the percentage increases.
Buyers can still find Office for Mac 2011 at the older, lower prices, however. Although Microsoft has boosted prices on its online store — as has Apple’s e-store, which also sells the suite — other retailers have not yet joined them.
Will Microsoft Buy A Slice of Dell?
Microsoft Corp is in talks to invest between $1 billion and $3 billion of financing in a buyout of Dell Inc, CNBC cited unidentified sources as saying on Tuesday.
Private equity outfit Silver Lake Partners is working to finalize a bidding group to take the world’s No. 3 PC maker private, and has started discussions with potential equity partners, sources familiar with the matter have said.
Dell also has formed a special committee to take a close look at any potential deal on the table, multiple sources with knowledge of the matter told Reuters. If successful, it would be one of the largest corporate buyouts since before the global financial crisis.
Microsoft, which accelerated its foray into computer hardware in 2012 with the launch of the Surface tablet, will provide the capital in the form of mezzanine financing according to CNBC, which is a hybrid of debt and equity.
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.
Sprint To Offer Ultrabooks
Sprint has become the first U.S. mobile operator to offer an ultrabook, which is being sold with a 3G/4G mobile hotspot device at no added cost.
Sprint and Lenovo announced the 13.3-in. IdeaPad U310 ultrabook with a hotspot device for $799.99, subject to a two-year Sprint mobile broadband service agreement, the companies said. Three months of broadband service will be available for free.
The hotspot is either a MiFi 3G/4G mobile hotspot by Novatel Wireless or the Overdrive Pro 3G/4G mobile hotspot by Sierra Wireless. Data plans for the hotspot start at $35 a month for 3GB, or $50 for 6GB.
Sprint said the offer is focused on small business users and students. It will be available through Sprint telesales at 800-Sprint1, Sprint business sales and business partners and on the Sprint ultrabook Web site.
The IdeaPad U310 features Lenovo RapidBoot, allowing it to resume from hibernate status in less than seven seconds, and BootShield for fast booting even with multiple apps installed.
