There is this KDE bug which will open by default any movie application with Kaffeine, even though another program is set to open these. One solution would be to completely remove Kaffeine, this way the next application in the default applications list will be used.
However, if you don’t want to remove Kaffeine, you can try the following steps:
Issue the following command in a terminal:
if is the input file, in this case the ISO image, and of is the output device. Replace /dev/sdX with the letter corresponding to your USB device (e.g. /dev/sdb).
In this tutorial I’ll show how to get some nicely colored man pages by adding several lines inside the .bashrc file, explaining what the code means and how it works.
GNU find is a powerful command-line utility that lets you search for files and folders in a hierarchical tree directory structure. It is the backend for all those utilities out there like the graphical searching in KDE or GNOME. However, find can be a little hard to handle at first by beginners. In this tutorial I will try to explain some of the capabilities of find, show some useful one-liners and provide more explanations regarding this command.

This file also contains options to adjust the timeout in seconds before GRUB boots the default OS (GRUB_TIMEOUT), change which OS should be selected by default (GRUB_DEFAULT, first entry being 0), and also the option to change the resolution used by default – GRUB_GFXMODE.
First of all I’d like to thank TuxArena’s readers for giving good feedback in the first part of this series, which overviews 15 of the tools I consider particularly useful in a console. This article overviews 10 more such tools, and most of them were suggested by you. Screenshots included.
telnet
telnet is a well-known command-line tool which uses sockets to open a TCP connection to the specified hostname and port. telnet can be primarily used for non-secure connections to connect to a HTTP server and get a file or to an IRC server for example.

AssaultCube is a popular cross-platform first-person shooter with pretty low hardware requirements, with a fast gameplay and many modes – including the classic CTF, TDM, FFA, or the popular TOSOK (Team One Shot One Kill), LSS (Last Swiss Standing), or HTF (Hold the Flag).
Starting a server should be pretty straightforward in Linux, all you have to do is run the server dedicated binary with several parameters, however AssaultCube provided a script, called server.sh for doing it. Here’s an example:
Not long ago Mozilla changed the release cycle of Firefox, so that major new versions (Firefox 5, 6 and so on) will be released every 2-3 months. Currently, the latest alpha release is Firefox 6 Aurora, while the latest beta development version is Firefox Beta 5, which has made it into the Firefox Next PPA already. Installing this version should be very easy if you follow the next steps.
I guess this has been around for some time, however I was not aware of it. I bumped into it in a thread on UbuntuForums, and decided to give it a try.
From the add-on page description, Flash-Aid is a Firefox 4 and 3.5 (and maybe 5 Beta too) add-on which was built to “Remove conflicting flash plugins from Ubuntu/Debian Linux systems, install the appropriate version according to system architecture and apply some tweaks to improve performance and fix common issues.”
