I found this nice software that can keep track of how long you have been doing something. It’s kind of like a remainder of the time that you had spend. Firstly if you want to install it you have to add this repository in your ubuntu box

  deb http://ppa.launchpad.net/hamster.support/ubuntu hardy main

after that you can install it by typing this

sudo apt-get install hamster-applet

and if you want to run it, you would have to type this command


/usr/lib/hamster-applet/hamster-applet -w

here is the screenshot

MAC address is the serial number of your NIC (network interface card), every computer in the world has a unique MAC address depends on the hardware vendor so they cannot be the same. However, if you are using linux then you can change the MAC address using the following command

firstly you have to bring down the interface that you are using

ifconfig eth0 down

after that then you have to enter new MAC address

ifconfig eth0 hw ether XX:XX:XX:XX:XX:XX

and then you have to bring up that interface

ifconfig eth0 up

then you will have a new MAC address in your linux computer.
