In 1947, American computer engineer Howard Aiken said that just six electronic digital computers would satisfy the computing needs of the United states. But obvious he didn't count the large amount of data produced due to scientific research and also the emergence of the Internet.

ENIAC (Electronic numerical integrator computer) world's first general purpose computer

As the electronic data and computation is increasing at an exponential rate, will human ever have amount of computing power he needs?

The answer to this might be beyond a supercomputer in the coming future, a "Quantum Computer" yes a computing device far more faster than the normal computers we know. Quantum Computer is a device which directly uses the "Quantum Mechanical" phenomenon.

In digital computers we have transistors for computation and all the work. In them data is encoded into binary digits we are all aware of i.e. 0s and 1s. Where 0 being the off/low state and 1 being the on /high state and each of the 0 or 1 is called a bit ( binary digit)

 But here in the quantum computers, instead of bits we have "qubits". The most fascinating thing about the qubits is that they can be 0 and 1 at the same time. What???? this might come in your mind but let us try it in a different way we can say that a switch can be on and off at the same time. Sounds crazy, but true.

Well how does it works. In contrast to transistors in digital computers a very small entity such as an atom is used to do do computing. Any thing like photon, a nucleus or an electron can be used as qubits. But, how can they be at the 0 and 1 state at once?

Let me explain you for example an electron of phosphorus is used as a qubit. All electrons have magnetic field around them as they act like a tiny magnets and this property is call spin. They would align themselves in the direction of the external magnetic field and let it be the 0 state. Now if you have to change the spin of the electron you have to apply some force and that would be the high energy state of the electron or the 1 state.

Now if we are able to align the electron against the magnetic field it would stay there. So far it is the classical 0 and 1 but the amazing thing about the quantum particles is that they can be aligned in both directions at same time. Now if we measure there spin it would be either 1 or 0 but once we measure. But, electron can exist in both states at same time and this amazing phenomenon is called the Quantum Superposition.

As we really can't calculate a superposition so the information before we know the actual spin of electron is lost. So, we have to make such logical operations that the information is not lost. Well this is the most hardest part about creating a Quantum Computer. Well so far as I know 48% of accuracy has been achieved by a Quantum computer calculation which is remarkable.

It might happen that next generation at our age have successfully installed a 100% accurate Quantum Computer at large Labs like CERN

Motorola launched Moto X 2nd Gen today after a long wait. The company has upgraded the device pretty much. Let's check out the specs of the device

Hardware

Getting to the hardware part there are pretty much interesting things the company has upgraded. First of all the side rim of the device is made of metal which gives the phone a premium feel. Screen is now 5 inches full HD AMOLED display. The device is also thinner from the older version.

Coming to the front look the device two significant front facing speakers just like the Htc One (M8). The speakers are slightly just above the surface which does not scratch the ear. Also, there is also one merit of this that if your device is kept the front face down then screen is protected from scratches. The two dots at the bottom of the device are IR sensors for gestures, like you can silent your device by just waving your hand above the mobile phone.

Now coming towards the back there is a 13MP camera surrounded by the ring flash but, here the ring actually does not illuminates. The two leds flashlights are installed inside the ring. Camera can record 4k UHD, 1080p and regular videos. Moto X comes in various of back covers we can order as we like.

On the sides the power button and the volume rockers are on the right side and the power button has a texture on it to distinguish between volume rockers and the power button.

Unluckily the phone has no external sd card slot. It comes only in two variants 16 gigs and 32 gigs

Software

Talking about the software part the device comes with the android 4.4.4 kikat upgradable to Android L. the phone comes with the stock android which Google releases it means no change in the OS and also fast update of the device  because Motorola itself has not to do and sort of "editing" in the OS.

The touchless display is now even more interesting now it's known as moto voice. We need not to even touch the device to access the voice control. Earlier user had to say the "Okay Google Now" to access the voice control now you can set your own keyphrase  like " You there kit" , " Help me kit".

It comes with built in third party apps such as Facebook , Twitter, Youtube and WhatsApp. But the company says that they will be coming with more third party apps in the device.

After the phones and bulbs it's time for helmets getting smart, Seems to be fascinating Skully Helmets Inc. San Francisco, California has developed a helmet having some really amazing features. The most interesting thing is that the helmet is based on the Android Platform. Helmet have features like rear camera, GPS and many other awesome features

Now getting to features some really classic features are there 

Besides these there are many more like Internet connection via smartphone, Open SDK to  develop your own apps for SKULLY Synapse(TM) and over-the-air updates to download new features as they are released.

 For further in detail description get to this SKULLY AR-1

Whatsapp which was acquired by facebook this year will soon add the voice calling feature to it, as the voice calling market is captured by Skype and Viber. Facebook the parent company of whatsapp will not add any kind of voice calling facility to it's messenger.

Whatsapp will get voice calling feature by the end of this year was announced by founder of whatsapp Jan Koum earlier this year at MWC Barcelona.

Jan Koum said

"We're adding voice to WhatsApp so people can stay in touch with friends and loved ones no matters where they are in the world"

"We use the least amount of bandwidth out there, and have optimized the hell out of it. We've made sure the quality is there, though, just like the messaging functons of WhatsApp"

Let's see how the voice calling feature works....

Imagining a plane without windows, horrible, right. But here we are not talking about really a plane without windows but a flexible large OLED screen instead of the conventional windows. Where the screen will show whatever the view outside the plane may be flying or on the runway. Passenger can change the view according to his wish, can surf net and check one's emails

A futuristic view of windowless planes.

The basic thought behind the replacement of windows with OLED screens is to reduce the fuselage weight which will automatically reduce fuel consumption and hence, the travelling cost. It has been found that for every 1% decrease in the fuselage weight there is 0.75% decrease in the fuel consumption.

The Centre For Process Innovation an organization of England that works on developing new products is working on this idea. The idea came about after discussions about how printable electronics in which the centre specialises , could be used. " We had been speaking to people in aerospace and we understood that there was this need to take weight out of aircraft." said Dr. Jon Helliwel of the CPI. 

Till now we are able to build curved transistors and curved screens. So, this thing is to be used in that idea's implementation. 

What you think about the idea comment below.

It's on nerves when it comes to our blood sampling the thought is really haunting about this thing. It seems that scientists at the University of Cincinnati and the US Air Force Research Laboratory are developing a system in which a Band-Aid like skin patch is able to gather and transmit the medical data in real time by analyzing patient's sweat and we just need a smartphone to read it as I found over the internet.

  

Developed by Prof. Jason Heikenfeld and his team of Uni of Cincinnati. The flexible patch contains electronic circuit, communication antenna, controller chip and a microfluidic paper-based sweat-sampling system. That paper wicks minute amounts of sweat from the skin in a tree root-shaped pattern, in order to maximize the sampling area.

A superabsorbent hydrogel is also contained in that patch to keep sweat flowing through the paper mechanism and to draw and store the sampled sweat. The gel swells only 2-3 millimeters even after several hours of collecting sweat.

Interesting part here is that the chip does not has it's own power source, it operates on the power drawn from adjacent smartphone's signal, just like passive RFID tag. The current prototype patch can measure concentration of sodium and chloride. In future there will many improvements. 

The data is wirelessly transmitted to an app on the phone. The tech may some day be used for applications such as keeping athletes from cramping up monitoring their electrolyte levels, non-invasively keeping tabs on premature infant's vital sign's allowing, diabetics to watch their glucose levels, or for fine-tuning medication dosages by measuring drug metabolites in the patient's sweat.

MIUI one of the most popular UI these days in basically in Asia since a four year old company out sold Apple in China. MIUI also fascinated me. A week ago my friend bought Xiaomi Redmi 1S and he liked it so much that he ordered 2 more smartphones for his brother and uncle. I also operated that device and liked it's UI and other features of this smartphone. I decided to flash MIUI in my Sony Xperia Neo v.

I also posted about Xiaomi on my blog under the heading " Why XIAOMI is loved by people? " Click the link to read.

Finally I downloaded the Rom From this Link. The Rom version which I downloaded was MIUI 5_3.8.16 which is recommended for my device. You can also download other versions but they lag.

After flashing the Rom the first think that came to my  mind was like i bought a new phone. It was different from all other Roms which I flashed earlier on my device. I found the was fluent and I simply loved it. Very similar to Apple's iOS.

                                       

The shutter speed of my camera increased, the quick settings panel is very user friendly. I found it easier than operating Android devices and all things which made MIUI different from basic Android devices were really good. I found it more user friendly.

But, as my phones config is very low comparing to today's world smartphones I found the Rom a bit laggy but  the overall experience is good I personally liked the Rom. One having the phone rooted and unlocked bootloader must try this Different Rom once.
