Jan 20th
Ubuntu makes it easy to enable automatic login if you’re using a login manager such as GDM. But what to do in case you don’t have GDM. Here’s how to enable automatic login.

Open /etc/init/tty1.conf as root:
sudo nano /etc/init/tty1.conf
Change the last line of this file to (where USERNAME is the username of the user you want to log in):

How to retain changes in Backtrack 4 installed on USB
Sep 19th
In this article we will describe how we can create a bootable Backtrack 4 USB Drive that will save all the changes we make on the USB itself. In this scenario we will use 2 USB Drives. One USB drive of 1GB and the 2GB USB drive which will hold our changes.
Firstly we need to create a bootable USB Drive on the 1GB USB Drive and boot our machine (A DVD Drive can be used also)
Instructions on how to do this can be found on the following link: http://www.itsolutionskb.com/2009/04/how-to-make-backtrack-4-boot-from-usb/

Increase Swap Memory in Linux
Apr 7th
In Linux, as in most other Unix-like operating systems, it is common to use a whole partition of a hard disk for swapping. However, with the 2.6 Linux kernel, swap files are just as fast as swap partitions, although Red Hat recommends using a swap partition. The administrative flexibility of swap files outweighs that of partitions; since modern high capacity hard drives can remap physical sectors, no partition is guaranteed to be contiguous. You can add swap file as a dedicated partition or use following instructions to create a swap file.
