How to create an Ubuntu package from source

How to create an Ubuntu package from source
Building from source has never been the most popular choice of the less experienced Linux users who are always in the seek for a pre-built package. This is especially the case with Ubuntu users who like convenience and GUIs over power and terminals. Unfortunately, everything in the Linux world gets first released as source, and then it gets packaged for the various distributions and architectures, meaning that you will most probably never find a package of the absolutely latest version of a software that got just released. Thankfully, building an Ubuntu package is a simple procedure that doesn’t require any technical or coding knowledge at all. Here’s a step by step guide on how to do it.

How to generate a animated GIF or movie out of images on Linux
It is very unlikely for anyone nowadays not to own a device that is capable of shooting many consecutive pictures (burst mode). While this is useful for helping you take the perfect shot in sport events etc, you may want to use some of those successive frames to create a movie. Thankfully, you can do this very easily on Linux. In this tutorial, I will use five (not so closely successive) shots of my Cockatiel parrot bird trying to drink some of my coffee.

How to safely wipe your data with Dariks Boot and Nuke bootable live CD
Sometimes, we need to completely and irreversibly wipe all data contained in a disk to keep them from falling into the wrong hands. This may not be something we are doing on a day to day basis, but if you want to do it, you should do it right and ensure that the data cannot be recovered by experts. One of the many ways of doing this is through Darik’s Boot and Nuke bootable live CD. This tool is made from the same team that develops the professional-grade Blancco data eraser, only it is available for free and without guarantee or support. The reason I like DBaN is because it is very simple to use and does the job fast.
