How to create A Huge File

You can create a file of any size using nothing more than what’s supplied with Windows. Start by converting the desired file size into hexadecimal notation. You can use the Windows Calculator in Scientific mode do to this.

Suppose you want a file of 1 million bytes. Enter 1000000 in the calculator and click on the Hex option to convert it (1 million in hex is F4240.) Pad the result with zeroes at the left until the file size reaches eight digits—000F4240.

1. Now open a command prompt window.
2. Enter the command DEBUG BIGFILE.DAT (replace the name of the file as you want) and ignore the File not found message.
3. Type RCX and press Enter. Debug will display a colon prompt. Enter the last four digits of the hexadecimal number you calculated (4240, in our example).
4. Type RBX and press Enter, then enter the first four digits of the hexadecimal size (000F, in our example).
5. Enter W for Write and Q for Quit.

You’ve just created a 1-million-byte file using Debug. Of course you can create a file of any desired size using the same technique.

Who is Still Using Windows XP, and Why?

The launch of Windows 8 is on the horizon, releasing later this year. Microsoft assures us the user experience with their new OS will be better than ever before, however; would it surprise you to learn that more than 3 out of every 10 PC users are still using Windows XP, an OS that is a full decade old? It’s true, and here’s why.

The Prodigal Software

Following in the footsteps of Windows 98 and 2000, which each had their share of issues, XP was hailed as being the most stable and easy-to-use product Microsoft had put out since Windows 95. In the five years between XP’s release and Vista’s, it lived up to its hype through regular and convenient software updates.
If It Ain’t Broke…

As both home and business users became used to XP, it became less and less likely that any significant improvements could be made with new software. This was reflected in the widespread release of office technology that was compatible with XP. The more invested corporations and individuals alike became in its use, the harder it would be to convince anyone a shift was worthwhile.
 

Vista Backlash

The only criticisms many had for XP were security issues. Microsoft promised a serious security upgrade with Vista, and for the most part, they delivered. But after word got out about the incorporation of intrusive DRM technologies, the higher system requirements, and the incompatibility issues with pre-Vista hardware and software, adoption was extremely reluctant. Many never “upgraded” at all, and for those that did, it was once bitten, twice shy.
Time to Change

Windows 7 resolves nearly all of the problems with Vista, but there’s a lot of work to be done to convince XP users to make the switch. XP has become expensive to maintain compared with upgrading to 7, however, and this may be the driving force behind a shift in the market. Another factor will be Microsoft’s removal of support for XP, including security updates and hotfixes, in April 2014. Anyone who relies on a computer knows how important it is to stay current when it comes to potential security problems.

In the tech world, you can’t stay behind for long, and many who mistrust Windows 7 will likely change their tune once they give it a shot. Hopefully the transition will be more painless than it has in the past!

How to Crack the Account Password on Any Operating System

Computer passwords are like locks on doors – they keep honest people honest. If someone wishes to gain access to your laptop or computer, a simple login password will not stop them. Most computer users do not realize how simple it is to access the login password for a computer, and end up leaving vulnerable data on their computer, unencrypted and easy to access.

Are you curious how easy it is for someone to gain access to your computer? If so, read on to see the technique one might use to figure out your computer password.

Windows 

Windows is still the most popular operating system, and the method used to discover the login password is 

the easiest. The program used is called Ophcrack, and it is free. Ophcrack is based on Slackware, and uses rainbow tables to solve passwords up to 14 characters in length. The time required to solve a password? Generally 10 seconds. The expertise needed? None.

Simply download the Ophcrack ISO and burn it to a CD (or load it onto a USB drive via UNetbootin). Insert the CD into a machine you would like to gain access to, then press and hold the power button until the computer shuts down. Turn the computer back on and enter BIOS at startup. Change the boot sequence to CD before HDD, then save and exit.

The computer will restart and Ophcrack will be loaded. Sit back and watch as it does all the work for your. Write down the password it gives you, remove the disc, restart the computer, and log in as if it were you own machine.

Mac

The second most popular operating system, OS X is no safer when it comes to password cracking then Windows.

The easiest method would be to use Ophcrack on this, also, as it works with Mac and Linux in addition to Windows. However, there are other methods that can be used, as demonstrated below.

If the Mac runs OS X 10.4, then you only need the installation CD. Insert it into the computer, reboot. When it starts up, select UTILITIES > RESET PASSWORD. Choose a new password and then use that to log in.

If the Mac runs OS X 10.5, restart the computer and press COMMAND + S. When at the prompt, type:

fsck -fy

mount -uw /

launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist

dscl . -passwd /Users/UserName newpassword

That’s it. Now that the password is reset, you can login.

Linux

Finally, there is Linux, an operating system quickly gaining popularity in mainstream, but not so common you’re likely to come across it. Though Mac and Linux are both based on Unix, it is easier to change the password in Linux than it is OS X.

To change the password, turn on the computer and press the ESC key when GRUB appears. Scroll down and highlight ‘Recovery Mode’ and press the ‘B’ key; this will cause you to enter ‘Single User Mode’.

You’re now at the prompt, and logged in as ‘root’ by default. Type ‘passwd’ and then choose a new password. This will change the root password to whatever you enter. If you’re interested in only gaining access to a single account on the system, however, then type ‘passwd username’ replacing ‘username’ with the login name for the account you would like to alter the password for.

Conclusion

There you have it – that is how simple it is for someone to hack your password. It requires no technical skills, no laborious tasks, only simple words or programs. The moral of the story? Encrypt your data to keep it safe. Don’t use only a password, but actually encryption, such as Blowfish or AES-128. There are a number of programs that can do this – TrueCrypt for Windows, or the native encryption found on Ubuntu, creating a disk image in Mac, etc.

Hibernate - Enable or Disable (restore or delete the hiberfil.sys file)

This tutorial will show you how to enable or disable hibernate and restore or delete the hiberfil.sys file inWindows 7 and Windows 8.
