Like most people, I am came from M$ Windows world so I have to find linux equivalent of many software

I find this site very interesting and useful:
http://linuxshop.ru/linuxbegin/win-l...en/table.shtml

It lists windows software and their linux's equivalent.

With apt-get, installing any software is a breeze on knoppix (debian)
Also, I recommend people support debian's popularity-contest. It will benefit the linux community as a whole.

Code:
apt-get install popcon
