When taking pictures of moving objects or scenes it would often be awesome to convert them into an animated gif. Unless you used a tripod you will still have slight camera movements and shifts which are then visible in the gif. There is a geekoverdose post which describes how to use the hugin commandline-interface for […]
After searching a while for a commandline music-players for linux and testing them I just settled down with cmus. Cmus is a feature rich music-player built using ncurses which provides a nice commandline based GUI.

To help me dealing with this problem I need a way to automatically add the file extension, which facilitates the process of reorganizing the recovered files.

In practice it seems like many SSH-users didn’t even know how to to verify that they are connected with the correct machine (man-in-the-middle attack). When to check fingerprints When connecting to a server for the first time SSH shows you […]
