How To Add Widgets,Apps And Links To The Google Crome

Now a days most of us make us of Google As a search Engine.But most of the people does not know about various features of the Google chrome. The Google Chrome now if we see  lots an lots of free and paid app that can be installed on or along with the Chrome Browser.So by installing these apps one can more optimize his PC. Moreover these apps are compatible with all the types of Operating Systems such as windows,Mac etc.

Web-based applications are programs that are designed to be used entirely within the browser. Using apps, you can do things like create documents, edit photos, and listen to music, without having to install complicated software.

These days, websites are capable of dynamic functionality that you expect from desktop applications on your computer. We call these robust sites web apps, or "apps" for short. If you use services like Gmail or Google Maps, you're already using apps! Apps have the following advantages over desktop applications:

• Apps install in seconds, with one click of a button. You don’t even have to restart your browser or computer.
• Your apps are always available. No matter what computer you’re using, you can always access your apps. Learn about syncing apps across multiple computers.
• Apps are always up-to-date. Because apps are hosted on the web where they can be instantly updated, you can be sure you're always using the latest version of the app that's available.
• Apps won’t crash your computer. If one app misbehaves, just close its tab in the browser. Your browser and computer won’t be affected.

Steps for installing free apps:-

You need a Google Account in order to install apps from the Chrome Web Store. A Google Account gives you a single username and password that you can use to access Google products and services. Don’t have an account? Create onein minutes.

1. Visit the store at http://chrome.google.com/webstore. You can also reach it by clicking the  icon in the Apps section of the New Tab page.
2. Browse or search for the app you’d like to install.
3. Free apps show an Add to Chrome button on their details page. Click the button to install the app. See a Buy for [price] button instead? 
4. The app automatically installs and its icon appears in the “Apps” section of the New Tab page. You'll see a prompt that points you to the  icon at the top of the browser window to open the New Tab page. To use the app later, go to the Apps section in the New Tab page and click on the app icon. You can also go to the item's details page in the store to click the Launch app button.

Some developers may offer free versions of their paid apps. If a free trial is available, you‘ll see a Try now button on the app’s details page. Click the button to install the trial. 

After installation:-

• Find and open your apps in a few different ways.
• Sync your apps to save your apps to your Google Account. This way, you can easily access them no matter what computer you’re using. 
• Uninstall an app: Open up a New Tab page and go to the Apps section. Drag the app into the "Remove from Chrome" button at the lower right corner. You can also right-click on the app and select Remove from Chrome.

What Is Compilier

• A program that translates an executable 
program in one language into an executable program in another language.

• we expect the program produced by the 
compiler to be better, in some way, than the original

Role of Compilers:

High-level programming languages provides following advantages -

• increase programmer productivity 

• better maintenance

• portable

but we require following Low-level machine details too! 

• instruction selection 

•  addressing modes

•  pipelines

•  registers & cache

• instruction-level parallelism

The Structure of a Compiler:

Multiple Phases

Modern compilers contain two (large) parts, each of which is often subdivided. These two parts are the front end, shown in green on the right and the back end, shown in pink.

The front end analyzes the source program, determines its constituent parts, and constructs an intermediate representation of the program. Typically the front end is independent of the target language.

The back end synthesizes the target program from the intermediate representation produced by the front end. Typically the back end is independent of the source language.

Advantage of  front/back end division 

This front/back division very much reduces the work for a compiling system that can handle several (N) source languages and several (M) target languages. Instead of NM compilers, we need N front ends and M back ends. For gcc (originally standing for Gnu C Compiler, but now standing for Gnu Compiler Collection), N=7 and M~30 so the savings is considerable.

The front and back end are themselves each divided into multiple phases. The input to each phase is the output of the previous. 

Sometime a phase changes the representation of the input.

For example, the lexical analyser converts a character stream input into a token stream output. 

Sometimes the representation is unchanged. 

For example, the machine-dependent optimizer transforms target-machine code into (hopefully improved) target-machine code.

Conceptually, there are three phases of analysis with the output of one phase the input of the next. The phases are called lexical analysis or scanning, syntax analysis or parsing, and semantic analysis

Cross Bar Resistive RAM

santa Clara-based startup Crossbar has just announced a potentially game-changing new memory chip that itclaims has the potential to replace standard flash memory in a number of applications.

Santa Clara-based startup Crossbar has just announced a potentially game-changing new memory chip that itclaims has the potential to replace standard flash memory in a number of applications.

Crossbar calls its new technology Resistive RAM, and says that it has the ability to store up to a terabyte of data onto a single chip that comes smaller than the size of a postage stamp. Not only this, but it can access that data twenty times faster than the current best of breed flash memory available, a feature that could easily disrupt a market said to be worth some $60 billion a year.

With flash memory being used in just about every ‘smart’ device these days – from iPhones to cameras to tablets – Crossbar believes that its Resistive RAM tech can lead to a fresh wave of innocation in consumer, mobile, enterprise and industrial devices. Importantly, the company isn’t the only one to share that belief – it’s also secured backing to the tune of $25 million from investors including Artiman Ventures, Kleiner Perkins Caufield & Byers, and Northern Light Venture Capital.

These are bold claims, but how can it be possible? Crossbar says that the key to Resistive RAM is its simple electrical structure, which consists of just three-layers of silicon-based material, including top and bottom electrodes, and a switching medium. The idea is that the voltage flowing across the electrodes creates a filament where the data can be stored. This filament is tiny – just 10nm – and can adjust to shrinking feature sizes. The company claims that its technology will provide ten years of retention and a lifetime of around 10,000 write cycles per cell.

You might be thinking that 10,000 write cycles is nothing special, but this is around ten times better thancurrent flash memory. Moreover, Crossbar’s chips use twenty times less power than regular flash when performing storage functions, which means that the battery life of devices could potentially be extended to weeks or even months. But by far and away the biggest advantage of Resistive RAM is its write speed – at twenty times faster than regular flash, dozens of issues that cause headaches for flash controllers would be eliminated.

Of course, Crossbar’s chips aren’t the only Resistive RAM technology hoping to disrupt the market. Various other concepts exist that promise faster write speeds and greater endurance, however these are not easy to manufacture. But this is precisely why Crossbar’s technology has such great potential – it can be manufactured simply with existing technologies and materials, something that bodes well for its ability to come to the market at a competitive price.

It’ll be a while for Resistive RAM to get off the ground – Crossbar says that consumer products using ReRAM probably won’t appear until 2016 at the earliest, but when they do the dream of carrying around a 1TB mobilephone in your pocket could soon become a reality.

How to hack wifi to get password from windows 7

There are many tutorials available over the internet which will help to crack wifi with a Linux machine.But here,I am going to tell you to do that stuff by using you favourite Windows 7 Machine.Truthfully it is much more easier when compared to do this stuff in Linux.Of course the tutorial to crack using a Linux box (Probably Backtrack) will be added shortly.So stay updated.

Tools Required:-

You have to download to 2 tools which I am sharing below in order to proceed.

1).CommView for Wifi: Download from:-http://www.tamos.com/download/main/ca.php
2).AirCrack-NG Gui for Windows: Download from:-http://www.aircrack-ng.org/

Steps:-

1).Install CommView.While installation you may be asked whether you want to install the apllication in VoIP mode or Standard mode.Both mode will work fine for our case.But I usually use the VoIP mode.It will automaically searches and installs the available drivers needed for making the wireless adapter to enable the packet capture (by turning on promiscous mode).Just allow it to install the needed drivers and you are good  to go to the next step.And please note that while using CommView,your wifi networks will get disconnected.Just dont panic,you are doing it right! :)

2).After the installation,start the application and click on the left arrow on the left side.                   

3).You will be prompted with a new window .Click on the "Start Scanning" button.

4).In the right column,all the available networks around you will be shown.Just click the network you want to get the password,and click on "Capture".Please note that,tjis tutorial is only for WEP Networks.

5).Now the newely opened windows will be closed and you can now see that the CommView started capturing the packets.

6).Click on the Settings>Options>Memoery Usage.Change the value of maximum packets in buffer to 20000.

7).Now you can click on the logging tab.Select "Auto Logging".Enter 2000 in the "Maximum Directory Size" and  20 in the "Average Log File Size".We just told the CommView to capture*.ncp packets with each file of 20MB size and store it in the directory we have chosen.

8).Again go to "Logging" tab and select "Concatenate Logs" to join all the split logs of 20MB we just created.And now we have one *ncf file

9).Go to File>Log Viewer>Load CommView Logs> and choose the *.ncf file that we just got from the above Concatenation step (Step 8).

10).Click File>Export>Wireshack/Tcp dump format.                                                    

11).Go to the Aircrack application folder and then tar verse to the bin inside. Double click  on Aircrack-ng GUI.exe. in the application,choose the *.cap file we just created in the (Step 10).

12).And that's it! If you got sufficient data to crack the password,you will get the password .It is advisable to proceed from step 8 to 11 only after receiving enough packets.You will need a minimum of 100000 packets to start the cracking.so after Step 7,it is advisable to leave the system alone for 2-3 hours and then proceed to the further steps.
