   (Go to account settings and change the password: https://www.facebook.com/settings?tab=account)
   
   

   Use some complex password (minimum 8letters, include small and capital cases, digits and special characters. Do not use your name or date of birth etc.)

2. Remove unwanted applications.

   Applications can access your data based on the permissions you have given. Best way is to use only trusted wanted applications. You can remove apps or revoke permissions from the app settings tab(https://www.facebook.com/settings?tab=applications)

Now you can travel in trains in India, without having a hardcopy(printout) of the e-ticket. Previously we have to take a prinout of the e-ticket booked from IRCTC. Now you just need to show the screenshoot of the e-ticket through laptops/palmtops/ Mobile phone and this is called Virtual Reservation Message (VRM). VRM along with any one of the eight prescribed ID proofs in original and the indication of the passenger(s)’ name(s) in the Reservation Chart will authorize the passenger to travel.

VRM along with one of the prescribed proofs of identity in original will also authorize the passenger to enter the platform on the day of journey and he/she will not be required to purchase platform ticket. ERS/VRM along with original id proof will be required to be produced on demand of Ticket Checking Staff on the platform.

This is a good move because many passengers have laptop/smart phone and they can show the e-ticket though that and there by saving the paper and ink.

One of the disadvantage of this method is, if we the passenger have to show a ticket as VRM though the laptop and if the laptop is not power-on, TTR have to wait till the passenger boot and logon to his/her system. And what will happen of the laptop’s or the mobile’s charge is completely drained/it is not working? So I think most of the people will not depend only on the VRM but they will take a printout of the e-tiket also.

The following photo identity cards are considered valid.

• Voter Identity Card
• Passport
• PAN card
• Driving License
• Photo identity cards issued by Central/State Government for their employees.
• Student Identity Card with photograph issued by recognized School / College for their students
• Nationalised Bank Passbook with photograph

Main Features of Firefox 4

• Firefox 4 includes an updated interface for all platforms that’s sleeker and easier to use.
• Firefox 4 contains huge performance enhancements, including our brand new JägerMonkey JavaScript engine. From faster start up times and graphics rendering to improved page load speed, you’ll notice the difference instantly.
• WebM and HD Video : As pioneers of HTML5 video standards, Firefox also supports the WebM format so you can watch open HD quality video.
• Protecting Your Privacy : Firefox puts your privacy first, fixing flaws in some web standards that allow bad guys to snoop around and expose your browser history.

• 3D on the Web: WebGL brings 3D graphics to Firefox, opening the door for developers to create vivid games and new kinds of visualizations and experiences for the Web.
• Audio API: Firefox is changing the way media is integrated on the web: exposing the raw audio data housed within the <video> and <audio> elements in HTML5 makes it easy for developers to use JS to read and write audio data.
• Retained layers: Experience super fast scrolling on complex web pages. Simply awesome.
• XPCOM: Firefox starts up even faster thanks to XPCOM module improvements that pave the way to a better extensions framework.
• Styling Pages with CSS3: Support for new CSS3 features like Transitions and Transformations makes it easy to add elegant animations to Web pages. Learn more
• Fabulous Fonts: Firefox 4’s OpenType font features gives designers and developers more control over a variety of font features—like kerning or ligatures—to create gorgeous websites.
• Upgrading Forms: Firefox integrated Form features like list attributes and HTML5 validation provide the tools to make annoying form implementation development a thing of the past.
• HTML5 Support: A new HTML5 parser and full support for web video, audio, drag & drop, and file handling means Firefox 4 is ready to run the best web apps of both today and tomorrow.
• Web Console: With this experimental analysis tool for modern sites, Firefox allows you to peek under the hood of dynamic web pages.
• JetPack SDK (Making Add-on Development Easier): Add-ons can be installed without restarting the browser, and can be developed more easily using the new JetPack SDK and js-ctypes
• Full Hardware Acceleration: Experience super-fast graphics acceleration with Direct2D and Direct3D on Windows, XRender on Linux and OpenGL on Mac, now enabled by default, on all supported hardware.
• SVG as Images: SVG files can now be used as images and backgrounds in Firefox, meaning that developers and designers can have stunning, performance-conscious websites with lighter, resolution-independent image files.
• Compartments: Firefox can now better manage JavaScript objects with Compartments, offering improved cache utilization and garbage collection mechanisms for better security, memory management and overall performance.
• Crash Protection: Firefox provides uninterrupted browsing for Windows, Linux, and now Mac when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins. If one of these commonly-used plugins crashes or freezes, it won’t affect the rest of Firefox. Instead, you can simply reload the page to restart the plugin and try again. Learn more about plugins.
• HSTS: Sites can now keep attackers from intercepting sensitive data while accessing the site by telling Firefox to automatically establish secure connections to their servers (https).

Method 1: Run Windows XP in Windows 7 using XP Mode and then run Turbo C from Windows XP. The new Windows XP Mode lets you run older Windows XP business software right on your Windows 7 desktop. Windows XP Mode comes as a separate download and works only with Windows 7 Professional and Ultimate. Windows XP Mode also requires virtualization software such as Windows Virtual PC. Both are available free on the Microsoft website. So if you are running Windows 7 Home Basic, this method will not work. So I am not explaining this method now.

Method 2: Using DOSBox

DOSBox is a DOS-emulator that uses the SDL-library which makes DOSBox very easy to port to different platforms. DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux, MacOS X…
DOSBox also emulates CPU:286/386 realmode/protected mode, Directory FileSystem/XMS/EMS, Tandy/Hercules/CGA/EGA/VGA/VESA graphics, a SoundBlaster/Gravis Ultra Sound card for excellent sound compatibility with older games.

DOSBox is totally free of charge and OpenSource.

So you can run old DOS Games and DOS programs using the DOSBox. Follow the bellow steps to install Turbo C IDE.

1. Download DOSBox . As of now the latest version is 0.74. Download Win32 installer for windows
2. Install DOSBox
3. Create a folder for Dos Programs. For example I am creating a folder ‘Dos’ in my ‘C’ drive.
4. Run DOSBox
5. In the DOSBox window, we can type the dos commands. First we will mount the ‘Dos’ folder to DOSBox. Type the following commands
   

   MOUNT C C:\Dos
   C: 

   

6. If you have Turbo C Installer, you need to install it. Step 7-10 are the installation steps. If you have the installed files ie a folder named TC or turbo c and inside that sub folders ‘BIN’, ‘BGI’ etc, goto step 11.
   
7. Copy the installation files to C:\Dos\TCSetup
8. Run the following command in DOSBox
   

   C:\Dos\TCSetup\INSTALL.EXE 

9. Change source drive to ‘C’ and press enter
   
10. We are going to install it to TC which is the default option. Select Start Installation by pressing the down arrow key and press enter. The installation will start and and you will get message once it is complete. Continue by pressing any key, close the read me me file. Now we are ready to run Turbo C
    
    
    
11. In the DOSBox command terminal, type the following command to get the Turbo C Editor. TC\BIN\TC.EXE
    
    
12. Write, compile, debug and run your programs
    
    
13. If you get any errors saying cannot include your header files like stdio.h etc… : Make sure that your Libraries are configured correctly. Goto Turbo C’s Option menu, select ‘Directories’ and make sure that Include directories path is ‘C:\TC\INCLUDE’ and Library Directory is ‘C:\TC\LIB’
    
14. You can Switch to Full Screen view or back to normal view by pressing Alt + Enter keys
