When I hear "mail merge," I usually think of personalizing letters and printing envelopes. However, many other projects can make use of mail merge.

One of the big advantages of typing in the Dvorak layout is the comfort that comes with it. It is estimated that you spend nearly 70% of your time typing on the home row, with only 30% of your time stretching for letters off of the home row. If that’s the case, then I should be able to type a great deal of words on the home row itself. Let’s see if that’s the case. Counting the number of words that I have on my Debian system, I get the following:

Full-featured traffic analyzers for Linux systems such as ntop and vnstat are widely available, but sometimes you just want a simple program that gives you fast, basic information about the amount of traffic going in and out of the hosts on your network.

Standing next to your laptop to control the slides during a presentation is not cool. Nowadays everyone uses a presentation device or their laptop's remote controller, but a presentation device can be expensive, few laptops come with a remote controller, and for those that do, Linux compatibility may be an issue. The Amora project turns your Symbian mobile phone into a Linux presentation device using Bluetooth.

VirtualBox is a piece of software that uses virtualisation to simulate a PC. With it you can run Windows, Open BSD or even Linux from your Debian system.

When your computer needs to run programs that are bigger than your available physical memory, most modern operating systems use a technique called swapping, in which chunks of memory are temporarily stored on the hard disk while other data is moved into physical memory space.

Previously, I blogged about 10 games that’s available in the Ubuntu Universe that I found interesting.
