PayPal releases mobile payment app for the Samsung Galaxy S5 fingerprint reader


With the Samsung Galaxy S5 now available, PayPal(s ebay) is making good on its promise to use the handset’s fingerprint reader. The company released mobile apps specifically for the Galaxy S5 and Samsung’s latest wearables on Friday. Using the phone app, you can log in to your PayPal account with a fingerprint scan instead of a typed password and make payments online or at participating retail locations that access PayPal payments.

PayPal actually announced the software in conjunction with the Galaxy S5 introduction at February’s Mobile World Congress. Until now, however, no devices were available to use the app. Here’s a short demonstration of how the PayPal app works:

The idea of using a fingerprint for account authentication over a typed password is rather timely, given how many sites are now affected by the massive HeartBleed security flaw may have exposed passwords on two-thirds of the world’s servers.

iOS App Driving Curve Is A Fitness Tracker For Your Car


iOS app Driving Curve is an easy way to track your driving performance without having to fiddle with additional devices.

Some high-profile driving apps, like Automatic, a Y Combinator alum and Techstars-backed Dash, offer their own hardware to connect with smartphones. Other use a Bluetooth-enabled on-board devices (OBD), which plugs into an adapter under the steering wheel.

Driving Curve, on the other hand, is meant as simple alternative for people who are curious about their driving performance, but don’t want to deal with an OBD or a more complicated set of features just yet.

“All you need is a smartphone, which dramatically lowers the entry barrier and grows our user base quickly,” says Tim Huang, who founded the app along with Duoyuan Chen. “We focus on quantified human behavior rather than machine behavior.”

To use the app, you simply press its start button just before you start driving…

Tests show iPhone 5s A7 chip is dual-core, still beats quad-core Android competitors


When Apple(s aapl) announced the iPhone 5s last week, it made a lot of noise about the 64-bit architecture of the phone’s new A7 chip. But other than that it remained pretty tight-lipped, which is how Apple tends to handle the specific details of individual components. But we have a better understanding, thanks to the chip review site Anandtech, of how the A7 processor powering the iPhone 5s is getting it done with a 1.3GHz dual-core chip.

You read that right. While many smartphone announcements today can feel like a spec arms race, Apple’s dual-core chip sounds positively quaint. But as we’ve seen demonstrated, more cores do not necessarily equal better performance. This holds especially true for the iPhone 5s, which was shown to handily outperform every quad-core Android phone it went up against.

Anandtech pitted the iPhone 5s against leading Android phones from HTC, LG, Motorola(s…

Why Zuckerberg Thinks Government Should Not “Move Fast And Break Things”


Silicon Valley has dramatically altered many aspects of our lives, but Congress still operates in the same way its horse-riding forefathers did. Facebook founder Mark Zuckerberg is not only optimistic about Congress, but thinks its general operating principles are A-OK.

“The cynical view is that everything is broken and sucks,” he told The Atlantic’s James Bennet at the magazine’s Newseum event yesterday in Washington, D.C. “My view is that the system is set up to avoid making catastrophic mistakes, and right now the country is really divided, and therefore few things should get done, except for the things that people really agree on.”

Like many in Silicon Valley, Zuckerberg is famous for running his multi-billion-dollar company at the edge of chaos with the philosophy “move fast and break things.” Employees are encouraged to ask forgiveness, not permission. Prototypes are quickly launched, piloted, improved, and then launched again. The lumbering giant…
