Download or Stream Video/Audio files from Youtube - Gmediafinder

Gmediafinder is a software to search stream an/or download audio or video files form YouTube and other similar sites and you also don't required browser or flash player, Gmediastreamer support full screen mode (double click on the video), visualizations, you can also select the preferred resolution for the playing the video files.

In addition to YouTube, Gmediastreamer supports the following search engines:
Dilandau: A European-run MP3 search engine that allows you to “Download music for FREE”, though with a limited catalogue.
MP3Realm: Now pointing to azmp3s.com, another slightly shady looking MP3 search engine that offers streaming, downloading and a lyrics lookup service. I’ve noticed not all files will stream, for some unknown reason.
Skreemr: An MP3 search engine that claims to deliver music, remixes, podcasts and ringtones and works well.
Tagoo: A Russian MP3 search engine, quite possibly legal in Russia but probably not anywhere else. Some adverts on the site are probably NSFW (not safe for work) but accessing via Gmediafinder gets rid of those anyway!
Imusicz: Another questionable search engine that comes with its own status page that you can check if your results aren’t showing up.

How to Install Gnome 3 on Ubuntu 11.04 (Natty Narwhal)

Unity is a shell interface for the GNOME desktop environment developed by Canonical for its Ubuntu operating system. Unity debuted in the netbook edition of Ubuntu 10.10. It is designed to make more efficient use of space given the limited screen size of netbooks, including, for example, a vertical application switcher called the launcher. Unlike GNOME, KDE Software Compilation, or Xfce, Unity is not a collection of applications but designed to be used with existing GTK+ programs.

Ubuntu has traditionally used the full GNOME desktop environment; founder Mark Shuttleworth cited philosophical differences with the GNOME team over the user experience to explain why Ubuntu would use Unity as the default desktop instead of GNOME Shell, beginning April 2011, with Ubuntu Natty Narwhal (11.04).

Recover deleted files using Foremost

Foremost is a console program to recover files based on their headers, footers, and internal data structures. This process is commonly referred to as data carving. Foremost can work on image files, such as those generated by dd, Safeback, Encase, etc, or directly on a drive. The headers and footers can be specified by a configuration file or you can use command line switches to specify built-in file types. These built-in types look at the data structures of a given file format allowing for a more reliable and faster recovery.

Originally developed by the United States Air Force Office of Special Investigations and The Center for Information Systems Security Studies and Research and now foremost has been opened to the general public.

Keed track of Configuration file changes under /etc - etckeeper

etckeeper is a collection of tools to let /etc be stored in a git, mercurial, darcs, or bzr repository. It hooks into apt (and other package managers including yum and pacman-g2) to automatically commit changes made to /etc during package upgrades. It tracks file metadata that revison control systems do not normally support, but that is important for /etc, such as the permissions of /etc/shadow. It's quite modular and configurable, while also being simple to use if you understand the basics of working with revision control.

etckeeper installation:
Open your terminal and type following command to install etckeeper:

sudo apt-get install etckeeper
