Signal will keep your iPhone calls private

Spooked that the NSA is snooping on your phone calls?
Then you might want to try out Signal, the app that encrypts your iPhone’s calls.
Developed by OpenWhisper Systems, Signal will encrypt your entire conversation using Amazon Web Services to re-route your data and using your same cell phone number; there’s no need for another one. What’s more is that your call’s metadata will be secure as well.
What’s cool about Signal is that it is an open-source project and is funded by contributors. The team behind Signal is also working on encrypted text messaging apps, so you can send secure SMS messages without worry.
Android users who are green with envy shouldn’t fret, as Signal will also be coming out for Google’s mobile OS as well.
Does anyone want to beef up their device’s security with Signal?

Alleged Meizu m4 phone leaks in images

Image
A new Meizu smartphone, alleged to be the Meizu m4, has leaked online. The leak - which comes in the form of a Weibo post- shows the device's images from TENAA, although the official TENAA listing for the phone doesn't seem to be live yet. Aside from images, the Weibo post also reveals some information about the device, including a metal body (with some plastic parts) and an RMB 899 (around $135) price tag. It also says that the phone doesn't feature a fingerprint sensor. Needless to say, none of this has been officially confirmed by Meizu. So, until that happens or we get the official TENAA listing, take this information with a pinch of salt. Via

You can now give New Paint a spin (unofficially)

Image
Perhaps as many of you, my image drawing and editing days started off on MS Paint. As you may have heard, Microsoft is completely revamping the app, giving it 3D capabilities. Twitter user Gustave M published the AppX file signed by Microsoft for the Windows Store, so it's easy to install (it only works on 64-bit devices, though). Find the download link in Gustave's tweet. I tried out the app quickly and drew this picture - okay, my artistic abilities are suspect and the app doesn't quite work right, but it has some powerful features. New Paint has a modern, tablet-friendly interface You can draw 3D shapes (couldn't find a way to do much with them, though) but my favorite feature is the 2D shapes. Several pre-made ones are available (free-hand drawing is possible too) and you can change the stroke. For the star, I used the star shape and told Paint to use the spray can tool for the outline, then gave it a fill color. There are no layers and o...

Watch Sony’s Fast Prototype Drone in Action

Image
Maximum speed of 106 mph.  Sony publically tested a prototype of its speedy airplane-looking drone that the company plans on putting to use serving business customers. Looking like a chubby concorde, the VTOL takes off and lands vertically like a Harrier Jump Jet. It’s capable of flying for more than two hours with a top speed of 106 mph (170 kph) and can carry a load of up to 22 pounds (10 kg). Sony’s joint-venture drone company called Aerosense is developing the device as part of Sony’s strategy to expand into enterprise markets. Aerosense will cater to business by offering automatically piloted services such as inspecting infrastructure and surveying land. “By making it automated, drones will be considerably safer because many of accidents today are caused by human errors,” chief executive of Aerosense Hisashi Taniguchi said at a news conference, according to The Wall Street Journal. Taniguchi told The Journal that Aerosense hopes to generate ¥10 billion ...

Nokia X and XL benchmarks

Image
Nokia X is a brand new platform but its app store felt acceptably full, considering it launched just a couple of days ago. There we found a couple of the usual benchmarks we run (there’s also the browser-based SunSpider) so we decided to find out how the Nokia X and XL stack up against the competition. The Nokia X prioritizes affordability over performance, Nokia made it clear that Lumia is its top performer. Still, the Moto G offers goodies like a quad-core processor (a Cortex-A7 no less) and a 720p screen, but it’s nearly double the price. The 4.5″ Moto G starts at €170, while the 4″ Nokia X and 5″ XL are €90 and €110 respectively.
