Everytime after you have reformatted the hard disk and reinstalled the Linux distro of your choice, the one troublesome thing that you need to do is to re-download all your applications and restore all the settings. This is made worst when your wireless connection just don’t work with the newly installed distro. How are you going to download all your applications when you can’t even connect to the Internet?

APTonCD aims to solve this problem by backing up all your packages into a Cd/DVD. You can then install your applications right from the CD/DVD. If you want to save up on CD, you can even store the data as an iso file and restore your system right from the ISO file.

Quite possibly the most distinguishing feature of Debian-based Linux distributions (such as Ubuntu, Mepis, Knoppix, etc) is their package system – APT. Also known as the Advanced Package Tool, APT was first introduced in Debian 2.1 in 1999.  APT is not so much a specific program as it is a collection of separate, related packages.

With APT, Linux gained the ability to install and manage software packages in a much simpler and more efficient way than was previously possible. Before its introduction, most software had to be installed either by manually compiling the source code, or using individual packages with no automatic dependency handling (such as RPM files).  This could mean hours of  “dependency hell” even to install a fairly trivial program.

In this article, we are going to highlight some of APT’s best features, and share a few of the lesser known features of APT and its cousin dpkg.  Believe it or not, APT can even be used to solve Sodoku puzzles!
