GOOGLE NEXUS 9

The Nexus 9 is available in 16GB and 32GB variants. While the 16GB Nexus 9 is Wi-Fi-only, the 32GB Nexus 9 supports 4G LTE. Both don’t come with support for microSD cards. The 16GB Wi-Fi model is already available  in India fro Rs 28,900.

It should be noted that the LTE version with 32GB storage space comes with a nano SIM slot meant only for Internet data, and doesn’t support calls. It offers 25GB of usable data.

In terms of specs, the Nexus 9 features an 8.9-inch IPS display with a 4:3 aspect ratio. The Nexus 9 features 2048 x 1536 pixels of resolution that places it at par with the Apple iPad Air. The Nexus 9 will be the first tablet to run Android 5.0 Lollipop, Google’s latest iteration of the Android OS. Here’s all you need to know about Android 5.0 Lollipop.

The Nexus 9 is powered by an NVIDIA Tegra K1 processor. This 64-bit dual-core Denver CPU should be able to handle all the multitasking, and heavy gaming and apps. The K1 offers Kepler GPU with 192 cores for smooth functioning of 3D graphics. It also includes 2GB RAM. It comes with an 8MP rear snapper with an f/2.4 aperture. The front camera has a 1.6MP resolution.

The Nexus 9 gets a major boost with a 6,700 mAh battery that could work for up to days, which is way higher than the 3,670 mAh battery integrated in the Nexus 7.

Cloud Computing

Cloud computing is is typically defined as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.

In cloud computing, the word cloud (also phrased as "the cloud") is used as a metaphor for "the Internet," so the phrase cloud computing means "a type of Internet-based computing," where different services — such as servers, storage and applications —are delivered to an organization's computers and devices through the Internet.

Cloud computing is comparable to grid computing, a type of computing where unused processing cycles of all computers in a network are harnesses to solve problems too intensive for any stand-alone machine.

Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.

Cloud computing, or in simpler shorthand just "the cloud", also focuses on maximizing the effectiveness of the shared resources. Cloud resources are usually not only shared by multiple users but are also dynamically reallocated per demand. This can work for allocating resources to users. For example, a cloud computer facility that serves European users during European business hours with a specific application (e.g., email) may reallocate the same resources to serve North American users during North America's business hours with a different application (e.g., a web server). This approach should maximize the use of computing power thus reducing environmental damage as well since less power, air conditioning, rackspace, etc. are required for a variety of functions. With cloud computing, multiple users can access a single server to retrieve and update their data without purchasing licenses for different applications.

The term "moving to cloud" also refers to an organization moving away from a traditional CAPEX model (buy the dedicated hardware and depreciate it over a period of time) to the OPEEX model (use a shared cloud infrastructure and pay as one uses it).

Proponents claim that cloud computing allows companies to avoid upfront infrastructure costs, and focus on projects that differentiate their businesses instead of on infrastructure.Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables IT to more rapidly adjust resources to meet fluctuating and unpredictable business demand. Cloud providers typically use a "pay as you go" model. This can lead to unexpectedly high charges if administrators do not adapt to the cloud pricing model.

The present availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture and autonomic and utility computing have led to a growth in cloud computing.

CAPTCHA

The term "CAPTCHA" means "Completely Automated Public Turing test to tell Computers and Humans Apart". A CAPTCHA is a type of challenge-response test used in computing to ensure that the response is not generated by a computer. It is a simple verification test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. A common type of CAPTCHA requires that the user type the letters or digits of a distorted image that appears on the screen. CAPTCHAs are used to prevent automated software from performing actions which degrade the quality of service of a given system.

Developers will try to come up with new and better tests, and spammers will continue to find ways of cracking them; it's very much a vicious circle. Perhaps, at some point in the future, somebody will come up with a test that is truly reliable and an uncrackable -- something that identifies humans in a way that cannot be faked.

• What is CAPTCHA?

  A CAPTCHA is a type of challenge-response test used in computing  to ensure that the response is not generated by a computer. The process usually involves one   computer  a  serve   asking  a   user   to complete a simple test which the computer is able to generate and grade. Because other computers  are   unable   to   solve    the CAPTCHA, any user entering a correct solution is presumed to be human. Thus, it is sometimes described as a reverse Turing test, because it is administered by a machine and targeted to a human, in contrast to the standard Turing test that is typically administered by a human and targeted to a machine. A common type of CAPTCHA requires that the user type letters or digits from a distorted image that appears on the screen.

  CAPTCHA (initiated by researchers at Carnegie Mellon University and IBM in 2000) works by understanding the OCR methods and displaying text that can break them. Of course this a game two can play, so OCR designers can modify their methods to read the distorted text.

  While CAPTCHAs started with text they have started using other images that maybe easy for a human to recognize but they baffle computers. Also, some of the new tests are not public so the technology is now called HIP that stands for
Human
Interaction
Proof.

4G Technology

     4G , short for fourth generation , is the fourth
generation of mobile telecommunications
technology, succeeding 3G and preceding 5G .
A 4G system, in addition to the usual voice and
other services of 3G, provides mobile
broadband Internet access, for example to
laptops with wireless modems , to
smartphones , and to other mobile devices.
Potential and current applications include
amended mobile web access, IP telephony ,
gaming services, high-definition mobile TV,
video conferencing, 3D television , and cloud
computing .

    
 First things first, the "G" stands for a generation
of mobile technology, installed in phones and on
cellular networks. Each "G" generally requires you
to get a new phone, and for networks to make
expensive upgrades. The first two were analog
cell phones (1G) and digital phones (2G). Then it
got complicated.
Third-generation mobile networks, or 3G, came to
the U.S. in 2003. With minimum consistent
Internet speeds of 144Kbps, 3G was supposed to
bring "mobile broadband." There are now so
many varieties of 3G, though, that a "3G"
connection can get you Internet speeds anywhere
from 400Kbps to more than ten times that.
New generations usually bring new base
technologies, more network capacity for more
data per user, and the potential for better voice
quality, too.
4G phones are supposed to be even faster, but
that's not always the case. There are so many
technologies called "4G," and so many ways to
implement them, that the term is almost
meaningless. The International
Telecommunications Union, a standards body,
tried to issue requirements to call a network 4G
but they were ignored by carriers, and eventually
the ITU backed down. 4G technologies include
HSPA+ 21/42, WiMAX, and LTE (although some
consider LTE the only true 4G of that bunch, and
some people say none of them are fast enough to
qualify.)
There are many different ways to implement LTE,
too, so you can't assume all LTE speeds are the
same. Carriers with more available radio
spectrum for LTE can typically run faster
networks than carriers with less spectrum, for
instance.
This confusion is why we run our annual Fastest
Mobile Networks story, which tests 3G and 4G
networks in 30 cities nationwide. In this year's
tests, we generally found that on speed alone
AT&T's 4G LTE network was the fastest, followed
by T-Mobile LTE, Verizon LTE, T-Mobile HSPA+,
Sprint LTE, AT&T HSPA, Verizon 3G and finally
Sprint 3G. As Sprint ramps up its faster "Spark"
LTE network, we expect its LTE speeds to rise to
competitive levels.

     If you like to surf the Web and especially stream
video, 4G can be heaven. If you connect a laptop
to your mobile link, 4G makes a huge difference.
In general, anything involving transferring large
amounts of data gets a big boost from 4G. Watch
out for the data limits on your service plan,
though; it's easy to use up a lot of data very
quickly with 4G.
If you have a 3G phone and you've been
frustrated with slow data, 4G may be the
solution. 4G won't solve any dropped call
problems, though, as all calls will be made over
older networks until carriers switch to voice-over-
LTE during the next few years.
Finally, if you want to future-proof yourself, get a
4G phone. 4G coverage is only going to get
better, and that's where the carriers are spending
most of their money right now. You can assume
that all 4G phones also support your carrier's 3G
and 2G networks as well.
Should You Even Consider 3G?
There are a few reasons you might still settle for
a 3G phone.
If your phone is mostly for voice use, you have no
need for 4G data. Save money and save battery
life by choosing a device without the high-speed
network.
If you live in an area that doesn't have 4G
coverage, there's no advantage to a 4G phone. In
fact, you'll have serious battery life problems if
you buy an LTE phone and don't disable 4G LTE,
as the radio's search for a non-existent signal
will drain your battery quickly.
If you're strapped for cash and buying a phone off
contract, you may have to settle for 3G to save
money. In that case, make sure to get the fastest
3G phone possible. On Verizon and Sprint, you
want to check that it supports "EVDO Rev A." On
T-Mobile and AT&T, you want the highest class of
HSPA+ possible: if not 42 or 21, then 14.4.

Amazing 3D printer

3D printing manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes.
In an additive process an object is
created by laying down successive
layers of material until the entire
object is created. Each of these
layers can be seen as a thinly
sliced horizontal cross-section of
the eventual object.

How does 3D Printing work?

It all starts with making a virtual
design of the object you want to
create. This virtual design is made
in a CAD (Computer Aided Design)
file using a 3D modeling program
(for the creation of a totally new
object) ór with the use of a 3D
scanner (to copy an existing
object). This scanner makes a 3D
digital copy of an object and puts
it into a 3D modeling program.
To prepare the digital file created
in a 3D modeling program for
printing, the software slices the

final model into hundreds or
thousands of horizontal layers.
When this prepared file is
uploaded in the 3D printer, the
printer creates the object layer by
layer. The 3D printer reads every
slice (or 2D image) and proceeds
to create the object blending each
layer together with no sign of the
layering visible, resulting in one
three dimensional object.

Methods and technologies of
3D Printing
Not all 3D printers use the same
technology to realize their objects.
There are several ways to do it
and all those available as of 2012
were additive, differing mainly in
the way layers are build to create
the final object. Some methods use
melting or softening material to
produce the layers. Selective laser
sintering (SLS) and fused
deposition modeling (FDM) are the
most common technologies using
this way of printing. Another
method of printing is to lay liquid
materials that are cured with
different technologies. The most
common technology using this
method is called stereolithography.
