The Marvel Cinematic Universe is one of the most ambitious film franchises put together by a studio, and perhaps the best thing about it is how every move made within it continues to build and add toward something bigger and better. With each new story we learn more and more about the world behind the silver screen, and we are always left with a perfect mix of satisfaction and want for more. Because of the intricate details of the comic book world, anything is possible, and it’s great fun to speculate about the implications of every twist, turn and maneuver as they lead to Marvel Studios’ second big landmark film: The Avengers: Age of Ultron.

The mega blockbuster is now nearly here as Phase II films like Shane Black’s Iron Man 3, Alan Taylor’s Thor: The Dark World, Joe and Anthony Russo’s Captain America: The Winter Soldier, and James Gunn’s Guardians of the Galaxy have all found their respective ways into theaters over the last two years. Obviously they all have a huge impact on the future of the MCU, but what do we know so far and how will it lead to next summer’s big movie? What is the latest development with all of the characters involved? Read on below as I break it all down, starting with the AMAZING new trailer!

Convert Android Phone or Tablet into PC Speakers

If you have no way of playing sound from your computer here's how to use an Android smartphone or tablet as PC speakers.
Whether you want to make use of an old device or your existing one has amazing speakers, you can play audio from your PC or laptop through your Android smartphone or tablet. Whether its from Spotify, iTunes, Windows Media Player somewhere else.

It's fairly easy to set up, doesn't require any cables and you don't even need the latest version of Android for it to work.
There are a few apps which bring this functionality including Airfoil Speakers and WiFi Speaker but we're going to focus on SoundWire.

The app is free but you can pay £2.50 for the full version if you want. "The free version of the application identifies itself by voice every 45 minutes and displays ads. There is a 10 minute compression trial in the free version. The full version enables unlimited Opus audio compression, can handle multiple clients (up to 10 connections), and has no ads or voice identification. It also has a special Pro Mode to set and display buffer latency precisely in milliseconds," explains GeorgieLabs.

Remove Internet Explorer in Windows 7 & 8

How to Remove Internet Explorer in Windows 7 and 8


Microsoft seems to have given up on Internet Explorer and is ditching it in Windows 10 in favour of a new browser code named 'Project Spartan,' but those running Windows 7 or Windows 8 will still find the notorious IE web browser on their computer. Here, we show you how to get rid of Internet Explorer.

How to uninstall Internet Explorer on Windows 7

If you're running Windows 7, you can uninstall Internet Explorer by clicking the Windows Start button and navigating to the Control Panel. From there, you'll want to click Programs, and then Programs and Features, which is the place you need to be if you want to uninstall any program.

To get rid of Internet Explorer, simply click on the Turn Windows Features on or off option on the left.
You'll want to find Internet Explorer in the list of features and then untick the checkbox next to it and click OK to confirm.

Then, you should press Restart Now to apply the changes. You should now find that Internet Explorer is gone from your machine.
Technically, you haven't uninstalled Internet Explorer with this method, simply hidden/disabled it, but it's a handy workaround nonetheless. Microsoft doesn't allow you to uninstall Windows features and Internet Explorer counts as one of those, which is why you're unable to completely uninstall it.

Hi Guys, Today I am going to discuss on a key-logger named KeyProwler. Let us start from the basics.
The first question is what is key-logger ?

Keylogger is a type of software which is used to monitor user activity by means of  Recording Keyboard Key Strokes, Capture Screen Shots without the permission of user.

Microsoft Windows 10 : New Cool Features

Microsoft just announced that the upcoming Windows 9 will, in fact, be called Windows 10. So let's discuss about 10 of the very best new features from Microsoft's upcoming Windows 10.
Talking about the New Name, Terry Myerson - Executive Vice President of Microsoft's Operating Systems Group - said that the Windows 9 name "wouldn't be right" given the new One Microsoft internal strategy. Hence the move to Windows 10.

1.Advanced and Sharp Designing.

Windows 10

Designed to appeal to experts and novices alike, Microsoft was at pains to point out that it hasn't given up on touch with the new OS. The Charms bar remains for the moment although we expect it to die if you're using a non-touch PC (check out Continum below).
Microsoft says it wants to support touch users who have persevered with Windows 8 and "evolve" the touch UI. (Translated: That means it is changing quite a bit.) The task switching will no longer work on the left. So with that and the charms going, that's goodbye to most of the problem with Windows 8 - and a whole philosophy down the pan.
Microsoft's Joe Belfiore said at the preview: "We want Windows 7 users to feel like they upgraded from a [Toyota] Prius to a Tesla, but they don't need to learn a new way to drive."

2.Start Screen is Back in Windows 10 in a New Way.

Windows 10

As we've covered before, the e most noticeable change is the new Start Menu, which looks somewhat like the old start menu. It brings some features from the Windows 8.1 Start Screen, such as live tiles, and can be resized.

Brain : A Mysteries Organ.

Brain is the most complex and mysteries organ in human body. It is the organ which can not be fully understand till now. Brain makes us differ from other animals on the Earth, because we have ability to think, understand, learn and the most important is speaking in languages.Brain can also live after our death for few seconds.Size of human brain is much greater than any other living being on Earth, and is also evolving now.Our forefathers have smaller brain than us, hence less intelligent than us.We can store a lot of information in our brain.

Most Neuroscientists are of the view that soon mankind will be able to open the closed doors of the human brain. What they mean is that we will be able to solve the unsolved mysteries of the brain. There is a lot more to the human brain that most of us can think. What’s more amazing is the fact that most people do not even care to explore their true cognitive potentials and abilities. 

You might have heard the thing that humans have only be able to use 10 % or 20 % or lesser amount of their brain. There are billions and billions of neurons inside the human brain. Just imagine how these cells work together with one another to shape, create and channelize everything we think, see and do. It would be a real achievement if we will be able to count the number of neurons inside the brain with high levels of accuracy. But wait. It is also said that human brain is something that will be never be able to understand. We will discuss more of it later, but now it is time to read about the 5 most amazing unsolved mysteries of the human brain.

Mars : Our Future home

All About Time Travel.

Really, I am very interested in Time Travel Theory. If we can capable to make it real, it will change our life, we can save anybody by travelling in past or can see what will happen in our future. Time Travel is not a joke, it is real. You can see below why I am saying....

We all travel in time. Another way to say that is that we travel in time at the rate of 1 hour per hour.
But the question is, can we travel in time faster or slower than "1 hour per hour"? Or can we actually travel backward in time, going back, say 2 hours per hour, or 10 or 100 years per hour?
It is mind-boggling to think about time travel. What if you went back in time and prevented your father and mother from meeting? You would prevent yourself from ever having been born! But then if you hadn't been born, you could not have gone back in time to prevent them from meeting.

 Who gave Time Travel Theory ?

The great 20th century scientist Albert Einstein developed a theory called Special Relativity. The ideas of Special Relativity are very hard to imagine because they aren't about what we experience in everyday life, but scientists have confirmed them.
This theory says that space and time are really aspects of the same thing—space-time. There's a speed limit of 300,000 kilometers per second (or 186,000 miles per second) for anything that travels through space-time, and light always travels the speed limit through empty space.
Special Relativity also says that a surprising thing happens when you move through space-time, especially when your speed relative to other objects is close to the speed of light. Time goes slower for you than for the people you left behind. You won't notice this effect until you return to those stationary people.

How Hard Disk Works ?

Today We are going to discuss about how hard disk works.Hard Disk is an important part of Computers, without it, you can not imagine the computer. But most of us don't know how it works, so this post is made especially for you.

If you are to uncover the hard disk drive by opening the top casing (after removing all the necessary screws), the first thing you'll see is a spindle holding one or a number of mirror-like hard rotating platters (commonly called data platter). The platters could be made to spin at an extremely high speed, technically between 5,400 to 10,000 revolutions per minute (RPM). An extremely thin magnetic coating is layered onto the surface of the platter that is polished to mirror-type smoothness.

The platter is usually made of glass or ceramic (modern platter may use titanium). Unlike a floppy disk, the platter cannot be bent or flipped and hence we say it as "hard disk" or "hard drive". Commonly a hard disk contains 1 to 10 identical platters that are stacked in parallel to form a cylinder. 
There is usually one Read Write (RW) head designated per platter face, and each head is attached to a single actuator shaft which moves all heads in unison and performs a uniform synchronous motion during reading or writing of data.

Why Memory Cards, Pen Drives comes in the form of 1GB,2GB,4GB not 3GB ?

As we all know computer use Binary Language to save and processing the information given by user. Binary Language is a language of two digits which is 0 and 1.


2^0 = 1GB
2^1=  2GB
2^2=  4GB
2^3=  8GB
2^4=  16GB  ................... and so on to 2^10=1024

Thats why Memory cards and Pendrives comes in the form of 1,2,4,8,16,32,........,

How Does Computer Work ?

Powering on the computer

When you first press the power button the computer sends a signal to the computer power supply,
which converts the alternating current (AC) into a direct current (DC) to supply the computer
and its components with the proper amount of voltage and electricity.

Once the computer and its components have received ample power and the power supply
reports no errors it sends a signal (using transistors) to the motherboard and
the computer processor (CPU). While this is happening, the processor will clear any
leftover data in the memory registers and give the CPU program counter a
F000 hexadecimal number. This number is the location of the first instruction and tells
the CPU that it's ready to process the instructions contained in the basic input/output system (BIOS).

BIOS and the POST

When the computer first looks at the BIOS, it begins the power-on self-test (POST) sequence
to make sure the components in the computer are present and functioning properly.
If the computer does not pass any of these tests, it will encounter an irregular POST.
An irregular POST is a beep code that is different from the standard one or two beeps.
For example, an irregular POST could generate no beeps at all or a combination of different
beeps to indicate the cause of the failure.

Download YouTube videos in few seconds.

Lets starts.

Who Come First Chicken Or the Egg

Of all life’s unanswered questions, there are two that stand out as being the most significant and the most difficult to resolve - the meaning of life, and the origin of life.

The meaning of life? The answer to why the Universe exists? Well, I guess you could say we’re halfway there, because we already know the answer. We just have to figure out what that answer means. And the origin of life? Amazingly, we're actually finally making some progress on that one, because a new study has shown you can create the most simple building blocks of life using three things that would have been present in abundance on early Earth - hydrogen cyanide (HCN), hydrogen sulphide (H2S), and ultraviolet (UV) light.

But first, a little background. There are currently two main hypotheses for how life on Earth began. There’s the RNA world hypothesis, which states that RNA was the precursor for life because it can carry genetic information while also mimicking the actions of protein catalysts, which is crucial for spurring on vital reactions. Then there’s the Metabolism First hypothesis, which proposes that certain types of metal catalysts could have given rise to the organic molecules needed to trigger early life.

Both of these hypotheses have struggled to answer the ‘chicken and the egg’ conundrum of life’s beginnings though, as Robert F. Service explains at Science Mag:
