Let's say you downloaded some videos of Youtube which all are a part of a larger video that was splitted into parts. A good idea would be to join those video files into one big file. Here's how to do that in Linux:

In Ubuntu (and most Linux distributions), your disks are checked every certain number of times your computer starts (using "fsck", "file system consistency check") to detect errors and correct them. If you're in a hurry, you can press the ESC key to skip this checking process and it will scan the disks the next time you start your computer.

Sometimes Firefox can become a real memory hog, especially if you keep it running for hours and have many tabs opened. In order to make Firefox a little more responsive and save some RAM memory, here are three tweaks I bumped into over time. Notice that most of these tips only free up some memory at the expense of (usually) loading speed for web pages.

QEMU is a powerful, open-source machine emulator which allows you to run virtually any operating system inside your currently running distribution. In this brief tutorial I'll show how to run distributions for which the ISO is available, directly from within Debian or Ubuntu.

Nano is a popular and user-friendly text editor for console which is mostly used for editing quickly configuration files, sources or various other text files. It does not compete with advanced development environments like Vim or Emacs, but it's fast and easy on resources.

Did you ever downloaded a single APE or FLAC file consisting of multiple songs? If so, it's quite annoying to try and listen to only one song. But you can split the files into multiple songs exactly like in the cue file (each song's start and end time are saved in the cue file, so we'll know where to cut the big file).

Over time K3b got its reputation as one of the most powerful burning applications not only for KDE, but for Linux in general. Development at the KDE4 release evolved rapidly in the last couple of months and the first usable alpha of the KDE4 port was put up for testing a few days ago, on April 22.

Fire up a terminal and type the following, one command at a time:

You may ask why would you want to install Firefox 3.6 alpha1pre Minefield in Ubuntu. Well, for testing purposes of course. While it worked ok for me in the 10 minutes browsing i used it, being in it's early alpha stages it should only be used for testing addons and to see the way web pages are rendered.
