Mobile payment is finally here

A new O’Reilly/PayPal report on web-native payment platforms, “ePayments: Emerging Platforms, Embracing Mobile and Confronting Identity,” is now available for download. Among the topics covered in the report are the rise of payment platforms, the mobilization of money, and the advent of contactless payment in mobile commerce. The following excerpt looks at three early mobile payment applications and what they might mean for mobile payment’s widespread adoption.
PayPal and Bling NationStop me if you’ve heard this before, but by this time next year you’ll be buying stuff with your phone. Oh, you have heard that before? Like, every year since the ’90s? Me, too. And like flying cars or 3D printers, they’re always just a little further down the road. But at the risk of being embarrassed again, I think the day is finally upon us.
You can already buy things using your smart phone, of course. On an iPhone, for example, you can buy digital goods like music or movies at the iTunes store. You can add an Amazon app and buy just about any kind of real good they sell and it’ll show up at your door. But it’s still rare to use your phone like a credit card in the physical world, waving or tapping it at a register and having the payment processed through the cloud.

In the past year or so, we’ve seen several experiments that signal the real deal is not far off. One involved PayPal and Bling Nation, a startup that offered RFID tags that mobile phone users could stick onto their phones for use at 150 or so merchants in the Silicon Valley area. Users could pay for services at the participating merchants by tapping the tag on a piece of hardware (called a Blinger) at the point of sale. Bling subtracted the purchase amount from a prepaid account or could bill it to the user’s PayPal account. It then texted a receipt and any relevant balance information to the user’s phone. A key feature of Bling’s system was the follow-up with future offers (for example, coupons on subsequent purchases) and rewards.
To protect against fraud, Bling’s technology used the equivalent of a one-time password, which was updated after each tap transaction to prevent replay attacks. The system had the potential to include real-time risk analysis that could trigger the request of a PIN for a transaction that falls outside of normal parameters. If the customer exceeds a predetermined rate of transactions, purchases an expensive item, or if Bling Nation notices a lot of geographic variability over a short period of time, when a consumer taps a BlingTag, she could be asked to supply a PIN. In this way, Bling Nation adapted from single-factor to multi-factor authentication based on a series of real-time risk analysis algorithms. (In the months since then, Bling Nation’s business model appears to have shifted from the technology to the rewards platform. )
Starbucks mobile payment screenWhile Bling Nation’s RFID and the upcoming near field communication, or NFC, technology we’re likely to see from Apple and Android rely on a close-range wireless system, Bump Technologies’ system works through the cloud, making the connection based on the proximity and similarity of “bump” of two devices. Bump’s system allows two mobile phones (iPhone, Android, or Blackberry) to exchange data when tapped together. That data, which travels through the network rather than via radio waves between the two devices, could be photos, contact information, or payment. PayPal’s mobile app relies on Bump technology to let two phone users tap payment from one phone to the other.

Facebook Investor Peter Thiel: Palantir Is The Next Facebook Or Google


Palantir CEO Alex Karp
Who isn’t looking for the next big tech company?
For a FORBES magazine story I recently wrote on cyber-security software-maker Palantir Technologies, I spoke with billionaire Facebook investor Peter Thiel, who said that Palantir is “tracking like the really great tech companies, like Facebook or Google.” Thiel thinks the company is the “most undervalued company in Silicon Valley” and will be worth around tens of billions of dollars in a few years’ time. Of course, Thiel is Palantir’s largest stakeholder, and his venture capital firm The Founders Fund has bankrolled much of the startup’s initial costs. But beyond the hype is a company that has accidentally stepped into the middle of controversy, is attracting some of the brightest engineers from top schools, and is making more money than anyone suspects.
Let’s start with the controversy. Up until a few weeks ago, only “Lord of the Rings” nerds knew what a “palantir” was (a seeing stone the company is named after). But recently, Palantir has found itself in headlines for putting together a proposal, along with HBGary and Berico Technologies, to launch cyber-attacks and other “dirty tricks” against Wikileaks and its supporters, on behalf of Bank of America, and against website ThinkProgress on behalf of the U.S. Chamber of Commerce. Pro-Wikileaks hacker collective Anonymous found the proposal and emails by hacking into the account of HBGary’s chief executive.
Palantir responded by issuing an apology and severing ties with HBGary. It has also put the 27-year-old engineer Matthew Steckman — who may have been responsible for putting the offensive tactics on the proposal (according to the emails) — on leave and launched an internal investigation. Some have implied that Palantir’s senior staff must have known about the proposal, given the importance of the clients. But Palantir chief Alex Karp says that’s not how the company works: “The idea that a 27-year-old wouldn’t have the ability to make a decision about our proposal is very foreign to how we work. It would go further up the chain if it was a proposal, but it wasn’t.”
Indeed, the 330-person company is largely comprised of 27-year-old “forward deployed engineers” who are given a lot of free rein to make decisions. But in an industry like cyber-security, young engineers may not have the experience to make the best judgment calls. Even Karp concedes, “There was an oversight breakdown on the proposal phase of our work and we regret that.”
Palantir will need to do some PR clean-up, especially among its applicant pool. The company competes with the Googles and the Facebooks for top talent. Palantir’s Co-director of Engineering Bob McGrew, a third-year Stanford Ph.D. candidate in computational game theory, turned down a job at YouTube offered by co-founder Jawed Karim to go to Palantir. McGrew says the company’s save-the-world “mission” sets it apart. Stanford computer science student Jake Becker says Palantir’s exclusivity in hiring the best of the best makes the company an attractive employer. But Becker also says that the Wikileaks flap “is seriously damaging their reputation on campus.”
Meanwhile, competitors sniff and say that Palantir isn’t doing anything particularly new in the industry. “They are taking a different approach which is trying to bring the Silicon Valley-esque to the beltway,” says i2 CEO Bob Griffin. A primary competitor to Palantir, i2 is a 20-year-old company whose cyber-intelligence software is known as the Microsoft Word of the industry. “The reality is at the end of the day there is no different approach. It’s all the same: it is what is the tool that allows customers to do what they do best.”
Recently, i2 and Palantir settled a lawsuit, in which i2 accused its competitor of corporate espionage. Griffin says only that he was “very satisfied” with the settlement.
But these controversies will likely wash over in time. Some investors have been betting big on Palantir. The company’s last round of funding of $90 million last June, led by an unnamed private equity firm, valued the six-year-old company at a whopping $735 million. Dave Kellogg, former CEO of business intelligence software maker MarkLogic, speculates in a blog post that “dumb money” might be involved here. “I think it means that… The company is trying to build and/or sustain a hype bubble and wants to be seen as hot. Most VC-backed companies do not disclose valuations,” he wrote. Kellogg also thinks Palantir is executing a “go big or go home” type strategy like PayPal did in its early days (Palantir was founded and backed by PayPal Mafia members), but he says he doesn’t see the same “landgrab market opportunity” here.
Other analysts and companies in the space agree, saying that Palantir’s revenues were probably around $25 million to $50 million last year. Gartner analyst John Pescatore says the market for “situational awareness tools” like Palantir’s is in the tens of millions of dollars, a fraction of the overall security intelligence services’ budgets, which are dominated by the likes of Raytheon, Boeing and Lockheed Martin.
But Karp says that he sees a “clear path” to $1 billion in revenue within the next five years. How close is he to that? Palantir’s 2010 revenue was “significantly north of $80 million”, said a highly reputable source familiar with the company who did not wish to be named. Karp says that Palantir’s revenues have been tripling every year since 2008 and that it became cash-flow positive in 2010.
Still $80 million or so is a long way from $1 billion. A lot will depend on how Palantir expands beyond its cyber-security niche. The signs could point either way here. It would not be a surprise if Bank of America did not end up using Palantir’s services anytime soon, given recent happenings. On the other hand, Palantir has already been able to line up a number of other top banks and hedge funds. One of these is JPMorgan Chase. Palantir signed a multi-year contract with the bank in December 2009 in the $5 million to $20 million range, and JPMorgan Chase Chief Information Officer Guy Chiarello gushes about the company, calling Palantir “the best bet I’ve made in quite a while.”
There’s no doubt that Palantir has a lot of bright young engineers working for them, but to really kick it up to the level of a Facebook or a Google, the company may need to start growing up.

NASA'S Chandra Finds Superfluid in Neutron Star's Core

NASA's Chandra X-ray Observatory has discovered the first direct evidence for a superfluid, a bizarre, friction-free state of matter, at the core of a neutron star. Superfluids created in laboratories on Earth exhibit remarkable properties, such as the ability to climb upward and escape airtight containers. The finding has important implications for understanding nuclear interactions in matter at the highest known densities.

Neutron stars contain the densest known matter that is directly observable. One teaspoon of neutron star material weighs six billion tons. The pressure in the star's core is so high that most of the charged particles, electrons and protons, merge resulting in a star composed mostly of uncharged particles called neutrons.

Two independent research teams studied the supernova remnant Cassiopeia A, or Cas A for short, the remains of a massive star 11,000 light years away that would have appeared to explode about 330 years ago as observed from Earth. Chandra data found a rapid decline in the temperature of the ultra-dense neutron star that remained after the supernova, showing that it had cooled by about four percent over a 10-year period.

"This drop in temperature, although it sounds small, was really dramatic and surprising to see," said Dany Page of the National Autonomous University in Mexico, leader of a team with a paper published in the February 25, 2011 issue of the journal Physical Review Letters. "This means that something unusual is happening within this neutron star."

Superfluids containing charged particles are also superconductors, meaning they act as perfect electrical conductors and never lose energy. The new results strongly suggest that the remaining protons in the star's core are in a superfluid state and, because they carry a charge, also form a superconductor.

Watch a brief animation of Cas A's neutron star:



"The rapid cooling in Cas A's neutron star, seen with Chandra, is the first direct evidence that the cores of these neutron stars are, in fact, made of superfluid and superconducting material," said Peter Shternin of the Ioffe Institute in St Petersburg, Russia, leader of a team with a paper accepted in the journal Monthly Notices of the Royal Astronomical Society.

Both teams show that this rapid cooling is explained by the formation of a neutron superfluid in the core of the neutron star within about the last 100 years as seen from Earth. The rapid cooling is expected to continue for a few decades and then it should slow down.

"It turns out that Cas A may be a gift from the Universe because we would have to catch a very young neutron star at just the right point in time," said Page's co-author Madappa Prakash, from Ohio University. "Sometimes a little good fortune can go a long way in science."

The onset of superfluidity in materials on Earth occurs at extremely low temperatures near absolute zero, but in neutron stars, it can occur at temperatures near a billion degrees Celsius. Until now there was a very large uncertainty in estimates of this critical temperature. This new research constrains the critical temperature to between one half a billion to just under a billion degrees.

Cas A will allow researchers to test models of how the strong nuclear force, which binds subatomic particles, behaves in ultradense matter. These results are also important for understanding a range of behavior in neutron stars, including "glitches," neutron star precession and pulsation, magnetar outbursts and the evolution of neutron star magnetic fields.

Small sudden changes in the spin rate of rotating neutron stars, called glitches, have previously given evidence for superfluid neutrons in the crust of a neutron star, where densities are much lower than seen in the core of the star. This latest news from Cas A unveils new information about the ultra-dense inner region of the neutron star.

"Previously we had no idea how extended superconductivity of protons was in a neutron star," said Shternin's co-author Dmitry Yakovlev, also from the Ioffe Institute.

The cooling in the Cas A neutron star was first discovered by co-author Craig Heinke, from the University of Alberta, Canada, and Wynn Ho from the University of Southampton, UK, in 2010. It was the first time that astronomers have measured the rate of cooling of a young neutron star.

Page's co-authors were Prakash, James Lattimer (State University of New York at Stony Brook), and Andrew Steiner (Michigan State University.) Shternin's co-authors were Yakovlev, Heinke, Ho, and Daniel Patnaude (Harvard-Smithsonian Center for Astrophysics.)

Microsoft releases Windows 7 SP1

Microsoft announced Tuesday that Windows 7 Service Pack 1 is now available for download via the Microsoft Download Center.
Most people will get Windows 7 SP1 via Windows Update, Microsoft said. For those updating a single PC or a home PC, the company recommends that you wait for that update.
"Remember - for Windows 7, SP1 will help keep your PCs well supported by delivering ongoing updates, many of which have been made previously available through Windows Update," Microsoft said in a blog post. "It does, however, include client-side support for RemoteFX and Dynamic Memory which are two new virtualization features enabled in Windows Server 2008 R2 SP1."

Microsoft released the Windows 7 and Windows Server 2008 R2 SP1 to its OEM partners on February 9, and they were made available to current customers of the Windows Volume Licensing program, as well as subscribers to Microsoft Developer Network (MSDN) and TechNet, on February 16. Dynamic Memory allows Windows Server Hyper-V administrators to increase virtual machine density without sacrificing performance, scalability, or security. RemoteFX allows for the virtualization of the Graphical Processing Unit (GPU) on the server side to deliver next-generation rich media and 3D user experiences for VDI (Virtual Desktop Infrastructures).

Intel's first-generation Light Peak I/O technology arrives, called Thunderbolt




   

Intel has announced the official release of its Thunderbolt technology, the first iteration of its much-awaited Light Peak. The new I/O technology is meant to become a unified interface that might one day replace the many interface protocols in use in the world today, everything from FireWire to SATA, HDMI to USB.
While Apple's MacBook Pro notebooks, the first devices with Thunderbolt built-in, are already available, no other devices have yet been released. Lacie, Seagate, and other memory and storage brands have announced thei support however, and we should see their first devices by the second half of 2011. Let us take a look at some of the features that Intel's Thunderbolt will bring to the PC table:
Rapid transfer rates - Intel's Thunderbolt is a dual-channel I/O technology that can be said to use features of both conventional PCI Express (PCIe) and DisplayPort protocols. This allows it to offer theoretical peak bi-directional transfer speeds of up to 10 Gbps, more than twice the speed of USB 3.0, which has a theoritical peak of 4.8 Gbps. 
Metal, not light - While Light Peak was known as an unconventional optic-based I/O technology, Intel has decided to make Thunderbolt, Light Peak's first iteration, using copper-wiring as the transfer medium. There were many reasons for this, and not the least of which would be the need for the entire ecosystem of Light Peak supporting devices to support a more complicated and expensive optical interface. Optic-based solution would not be able to provide power via the cable either, limiting Light Peak's USB replacement ambitions. Nevertheless, Intel has managed to hit their self-assigned targets for Light Peak, making Thunderbolt capable of 10 Gbps regardless of its copper-based heritage. Withn the next decade, Intel says Thunderbolt or Light Peak technology would be capable of speeds nearing 100 Gbps, using optical solutions, or at least, optical cabling.
Port cannibalization - Intel has designed Thunderbolt to work over PCIe and DisplayPort transmission protocols, and, would require a special port to be able to use both channels efficiently. In the new MacBook Pro, the Thunderbolt port is suspiciously similar to a Mini DisplayPort interface, leading one to believe that any DisplayPort cable or adapter would work on it as well. Optical transceiver - While this technology will need to be perfected further before Intel's theoretical 100 Gbps transfer speeds, Intel's use of miniaturization on the optical transceiver helped the company create Thunderbolt, converting electricity into light and back in a mechanism the size of a small coin. The transceiver comprises two Vertical Cavity Surface Emitting Lasers (VCSELs) lasers and photon detectors. The width of the fiber-optic cabling is just 125 microns wide.
Protocol coherence - Intel uses a controller chip to manage the complicated protocol-switching capabilities required to allow myriad protocols to run over a single cable and port. This leads to the emergence of a universal port in time, and in the meanwhile, give cost and space savings in the form of cables and ports.
Sufficient cable length - While the current copper-based implentation will suffer marginally compared to the final, optical solution, it is still larger than the maximum lengths of USB cables. In the future of Light Peak and Thunderbolt however, pure optical cables could measure up to 100 metres.
Check out a short video below of an Intel Thunderbolt MacBook Pro setup that is transmitting four 1080p HD streams simultaneously. For more information about the technology, visit Intel's Thunderbolt page.
