Remove Warnings & Notices From Psychostats

I was testing the psychostats script today and while testing I found that it displayed lots of warnings and notices that make the script look so bad as the output is totally messed up. This post will help you to fix this problem.

At first, I tried to change the error_reporting and display_errors setting in php.ini file but I could not get rid of those errors. So I then put a line of code as below at the top of index.php file of psychostats. Still no luck. Finally, I navigated to ./includes relative to psychostats root folder where there was a file named class_PS.php. Open this file and type the following line below <php line.

error_reporting(0);

This will suppress all those errors and will make your psychostats look better. I hope this helps.

I was downloading the metasploitable to play around with it and I found that it was the VMWare .vmdk file so I had to convert it into .vdi file to run under the virtualbox. This post will show you how to easily convert the .vmdk file into .vdi file.

Note that you need to have virtualbox installed for this to work. I hope this helps. :)

Get High Compression Ratio With KGBArchiver

So you are wondering how you could compress your 2gb game data into less than 100 MBs? Are you lacking hard disk space and want to store files in the compressed form? If yes, then this post will direct you towards the solution.

KGB Archiver is the compression tool with unbelievable high compression rate. It surpasses even such efficient compression tool like 7zip and UHARC in terms of the abilities. KGB Archiver uses AES-256 encryption to encrypt archives. While the compression ratio is very high, it requires relatively high PC specification and it also requires more time to compress and decompress the file. But still this compression program will come in use sometimes.

Physical Memory Acquisition With MDD

MDD is a physical memory acquisition tool for imaging Windows based computers created by the innovative minds at ManTech International Corporation. MDD is capable of acquiring memory images from Win2000, XP, Vista and Windows Server.

This tool can be pretty useful to analyze the data present in RAM. Whenever we are running programs, RAM stores various range of information being used by the program.

Thus, MDD can be very useful tool to dump the physical memory into the file from which we can extract the required information.

Reset Forgotten Ubuntu Password [How To]

If you've forgotten your ubuntu user password, it is still possible to recover the account by resetting the password. The recovery mode option in the grub menu can be used to reset the ubuntu user password as this mode lets us drop to the root shell prompt.

To reset the password, first select the recovery mode from grub menu. And then you'll have to select the "Drop to shell prompt" option. Now you can simply reset your password by using the passwd command.

passwd <yourusername>

Replace yourusername field with your username for ubuntu login and then you'll be prompted twice for new password. Enter the new password and you're done. Just reboot the system and this will successfully reset the password and you'll be able to access your ubuntu account. I hope this helps. :)
