Yet, default [Ubuntu] functionalities are not enough to turn a Windows-7-addicted into the Ubuntu lover I want him to become. In fact, Ubuntu new-comers get shocked by the new interface gnome offers, and frustrated when they find no flash support for their browsing. Hence, in order to fill that gap, I find myself downloading, installing and configuring new features, like compiz for visual effects, closed-source codecs for medias, system upgrades for more stability, a more friendly theme, etc...

We will create a mini-calculator that, by the end of this tutorial, should look like this:

As usual, I'll be using a ubuntu box, as well as Qt 4.7. Qt is cross-platform, so don't worry if you're using another Linux flavor or Windows: the steps are almost the same :)

In this post, I'm going to show you how to create your custom ubuntu flavor using remastersys. In my case, I've a ubuntu 10.10, on top of which I've installed Cheese (for webcam support), and Tumiki Fighters (my favorite game). I also use Radiance theme. And I want to export the whole thing to a .iso live DVD. Don't worry, it's a piece of cake ;)

Once upon a time, there was Sun's OpenOffice

Sun, was the company behind OpenOffice.org (and other major open source projects such as MySQL, VirtualBox OSE, and OpenSolaris). By January 2010, Sun was aquired by Oracle.

Oracle, and let me put this straight, are people who don't give a darn about open source.

According to Forrester Research, the majority of security breaches involve internal employees, with some estimates as high as 85 percent. So what if an employee of yours launches a local attack without casting a single packet? Host based Intrusion Detection Systems, namely OSSEC, are a solution.

Next, you'll have to choose between a Dynamically expanding storage and a Fixed-size one.

In Dynamically expanding storage option, you'll have to specify the limit of the disk space you want to allocate to your VM. Physical hard disk space will be dynamically consumed, depending on the virtual one. So If you specify a limit of 10 Gigs for your VM, and have only used 3Gigs, your hard disk space will be 3Gigs short. In Fixed-size storage, you specify the disk space, and it's statically assigned to your VM, no-matter how much of it you actually use.
In short, Dynamically expanding storage is the clever choice, so go for it:

With Ubuntu, you don't need to look for 10 multimedia players and different codecs and pluguins in order to visualize videos and browse websites correctly. It's just a single package, called "ubuntu restricted extras", that you need to install, than you'll be able to play and browse (almost) every audio/video format.
