If gnome-do fails to locate and launch terminal (or gnome-terminal), it is because of a small omission in the gnome-desktop.terminal file.

In terminal run:

locate gnome-desktop.terminal

Once you find that file, open it using nano or gedit with sudo.

sudo nano /usr/share/applications/gnome-terminal.desktop

Search for the line that says:

OnlyShowIn=GNOME;Unity;

Add X-Cinnamon to the end of that line such that it reads.

OnlyShowIn=GNOME;Unity;X-Cinnamon;

That’s it. Once you log out and log back in, terminal will start appearing as one of the search results in gnome-do.

In Linux Mint 16 and 17, there is a small bug in gnome-do. Well, techincally it is in a file called gnome-terminal.desktop

Searching for terminal in gnome-do in Cinnamon environment gives no results for gnome-terminal. The first entry is usually Printers. This is caused because of an omission in the gnome-terminal.desktop file.

Open terminal by searching through start menu:

locate gnome-terminal.desktop

You will usually find it at: /usr/share/applications/gnome-terminal.desktop

sudo nano /usr/share/applications/gnome-terminal.desktop

Find the line that says:

OnlyShowIn=GNOME;Unity;

To that list add X-Cinnamon so it will read.

OnlyShowIn=X-Cinnamon;GNOME;Unity;

Save the file and log out. Once you login again, terminal should appear on top of Gnome-do search as soon as you type t.

Every once in a while as you are trying to make a .iso file from a DVD using Brasero, you might get an error saying that couldn’t retrieve the keys because of libdvdscc2.

An alternative to that is a command line tool called dvdbackup which first needs to be installed

sudo apt-get install dvdbackup

After installing that program, you can make backup of your entire dvd, unfortunately not an .iso. You can create an iso from the folder that gets generated once you backup the dvd using dvdbackup. To create a backup, open your terminal and run:

 dvdbackup -M -i /path/to/dvd/  -n Title_For_Backup -o /path/to/output/directory

To get help of dvdbackup you simply have to type in dvdbackup at the terminal.

As a prank project we installed a webcam at the front desk of the our office suite, and plugged it into a Linux machine. Then we had a decommissioned 14 inch monitor face the person who was just walking in so that he/she could see themselves in the monitor with absolute clarity. The text beneath said “Smile for the camera”.

This was an one line implementation with VLC. The terminal command for this would be:

vlc --sub-filter "marq{marquee=\$t \$\smile for the camera,color=16776960,position=8}" v4l2:////dev/video0

A false sense of security with some false video surveillance. Of course you can save the stream and turn it into real surveillance.
