Top Five Cloud Storage Services

Cloud storage lets you access (and store) your text or other files, folders irrespective of their size. The cloud phenomenon is spreading like wild fire and of late more new cloud services have surfaced leaving us with more options to choose from. Here we share with you the top five as deemed by the experts.


1. Mega : It is a sequel to Megaupload. The website became active earlier this year. Kim Dotcom, the founder of Megaupload, who is stationed in Kiwiland registered this website as mega.co.nz.

Mega gives 50GB free storage. This is an encrypted service for security reasons which relies on advanced version of AES rules.

2. Ubuntu One : This is a personal service that combines personal cloud and digital world. It boasts of various services like heavy storage, storing, It includes storage, synchronisation, file and data sharing, and audio visual streaming.

With 5GB free storage, a/v streaming, there is a bonus of up to 20GB extra storage free of cost courtesy the referral programme. As of now, Ubuntu One is compatible with Windows XP and higher versions, Mac OS X 10.6, and Android platforms and a few Apple devices.

3. SpiderOak : It is used for making back up files, data sharing, data storage, and synchronisation. It uses encrypted rules for security reasons.

SpiderOak has two account types, a free version with 2 GB storage, and a paid one for higher capacity. Referral links can be created and as a bonus with every new link, you get 1GB. You can use it for Windows, Android, Mac, Linux, N900 Maemo and iOS mobile platforms.

4. Microsoft SkyDrive : From the house of Microsoft, it lets you upload files, sync them, access them from your browser.

It offers 7GB free storage for the debutants and for students it gives 3GB free storage for one year.. you can get it via SkyDrive for Windows and OS X.

5. MediaFire : It is a free file and image hosting web site that offers up to 50GB storage. MediaFire lets you form your own image galleries, view/share document, make a/v presentations. It is fit to be used as a transient podium for back up. MediaFire supports Linux, Mac OS X, and Windows on the desktops and Android and iOS on smartphones and tablets.

What is “Touchscreen”? Which one is best?

What is “Touchscreen”? Which one is best? “Capacitive touchscreen” or “Resistive touchscreen”?

A touchscreen display is one that is sensitive to touch. They are often used on smartphones and similar devices. In the cell phone industry there are two major categories of touchscreen displays: “Capacitive touchscreens” and “Resistive touchscreens”.

What is “Capacitive touchscreen”?

Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touching. Because of this, capacitive displays can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand.

Examples of devices with Capacitive touchscreens are the Apple iPhone, Nokia Lumia 620 and the Sony Xperia p.

What is “Resistive touchscreen”?

Resistive touchscreen displays are composed of multiple layers that are separated by thin spaces. Pressure applied to the surface of the display by a finger or stylus causes the layers to touch, which completes electrical circuits and tells the device where the user is touching. As such, resistive type touchscreens require much more pressure to activate than capacitive touchscreens.

Examples of devices with Resistive touchscreens are the HTC Touch Diamond, Nokia Asha 305 and the Samsung SGH-i900

Soon You’ll Be Able To Click Pictures In Dark Without Flash

This new sensor is reportedly sensitive to both visible and infrared light.

Imagine you never have to again bother about the lighting when you want to capture moments! Well, this could actually be true if this latest research goes commercial (and find takers). A team of researchers at the Nanyang Technological University (NTU), Singapore created a new and cheap imaging camera sensor, which they claim to be 1,000 times more sensitive to light. This means you can click high quality pictures even in low lighting.

This new sensor is reportedly sensitive to both visible and infrared light. It will be suitable for cameras from family cameras to surveillance and even satellite cameras.

The reason that the sensor is able to capture 1,000 times more light than the existing imaging sensors is because it attains high photoresponse from its unique structure. “The sensor has been developed from graphene, which is a super strong carbon compound with a honeycomb structure that is as flexible as rubber, more conductive than silicon and which resists heat better than a diamond,” TechNewsDaily reported.

Wang Qijie, the inventor of the sensor said, “We have shown that it is now possible to create cheap, sensitive and flexible sensors from graphene alone. We expect our innovation will have great impact not only on the consumer imaging industry, but also in satellite imaging and communication industries, as well as the mid-infrared applications,” said Wang.

The nanostructures hold onto light-generated electron particles for much longer than conventional sensors. This results in a stronger than usual electric signal, which can be processed into an image, like a photograph captured by a digital camera, an ET report added.

3D-printed Robohands are helping kids without fingers

People who have lost fingers can try to get robotic hands that cost tens of thousands of dollars. Or they can try to 3D-print their own hand.

That’s what Richard van As did after a woodworking accident in 2011 cost him four fingers. The South African carpenter decided to build his own fingers from hardware store parts but eventually turned to 3D printing.

Using a MakerBot Replicator 2 printer, he collaborated with Ivan Owen to create a prosthetic finger after much trial and error. They’ve since printed hands for four South African children who lack fingers.

The first was Liam, a 5-year-old boy withamniotic band syndrome, who was born without fingers on his right hand. At the request of his mother, Van As and Owen produced Robohand, a low-cost, 3D-printed prosthetic.

The Robohand works by a series of cables and bungee cords that are controlled by movements of the wrist and arm.

Check out this video of Liam using his Robohand, performing precise movements like picking up coins.

Aside from distributing the open-source files for Robohand on Thingiverse, the partners are now trying to raise $10,000 in an Indiegogo campaign so they can help more children for free.

The cash is needed to buy materials such as PLA plastic for the 3D printer and hardware to assemble the hands.

Open-source alternative for Coke!

Have you ever had a can of Coke and thought that it would taste better if it was open source? No? Well, some people have and they have created the world’s first “open source” cola. And it’s on version 1.1.3

Anybody can make the drink, modify and improve on it as they see fit, as long as the recipe is made public under the GNU General Public License. However, recipes are not copyrightable, so the legal basis for that premise is untested.

Originally released as a promotional tool to explain open source software, the drink became a success and the company that made it sold 150,000 cans, and the creators became better known for the cola than for the software they were trying to promote!


Where Files Are Stored On Internet?

The internet is a collection of a large number of client-server based systems. So all files and other resources on it are stored on secondary storage devices of the respective servers. Servers of websites are termed as web servers. So when you type in a URL of a website in the address bar of your browser, it makes a connection to that web server which in turn fetches the data from the secondary storage device (such as the hard disk) that they must be using and returns it to the respective browser. The same holds true for any other resource (image, MP3 file, zipped file, etc.) that you access on the internet.
