Network security is an ever growing need these days. You never know what you’re going to find when you step out into the wild world of the internet. Luckily we’re all using Ubuntu so we’re much more protected than most of the world, but there still is reason to protect our computers and networks.

For those of you that are not behind a hardware router (if you don’t know this might be you) you definitely want to install a firewall for your system.

Setup a Desktop Firewall with Firestarter : Ubuntu (5.10 / 6.06.1 / 6.10)

And: Using Firestarter


Skype is a little piece of software that lets you make free calls to anyone else on Skype, anywhere in the world. And even though the calls are free, they are really excellent quality. If you and your friends, family or business contacts are using webcams, you can also make free video calls. You can even call landlines and mobile phones at really cheap per minute rates (and there’s no setup or subscription fee).

Install skype in ubuntu

First you need to download the latest .deb package from here using the following command:

As part of my work on Xen I've been playing with Xephyr (a replacement for Xnest). My plan is to use Xen instances for running different versions of desktop environments. You can't just ssh -X to a Xen image and run things. One problem is that some programs such as Firefox do strange things to try and ensure that you only have one instance running. Another problem is with security, the X11 security extensions don't seem to do much good. A quick test indicates that a ssh -X session can't copy the window contents of a ssh -Y session, but can copy the contents of all windows run in the KDE environment. So this extension to X (and the matching ssh support) seem to do little good.

One thing I want to do is to have a Xen image for running Firefox with risky extenstions such as Flash and keep it separate from my main desktop for security and managability.

When you install a dual-boot of Ubuntu, one of the frustrating things that you’ll immediately notice is that Ubuntu is now set as the default operating system in the Grub loader. There’s an easy way to switch back to using Windows as the default.

To make this change, you’ll first have to boot into Ubuntu, and then run the following command:


Set Windows as Default OS when Dual Booting Ubuntu


This article is about resizing ext3 partitions without losing data. It shows how to shrink and enlarge existing ext3 partitions and how to merge two ext3 partitions.

I have mp3 music file all over my file system. I’d like to move them onto specific directory called /mnt/mp3. So how do you find and move all mp3 files to /mnt/mp3 directory?

Simply use find command. It locates all files and then executes a command to move them to /mnt/mp3 (any other directory).

Finding all .mp3 files and move to new directory from shell prompt


A quick note for anyone wondering how to enable core dumps from within most Linux distributions.

1. First, make sure debug symbol are enabled in your project’s configuration (in configure.ac if you’re using autoconf).

Staying in front of your computer for hours and hours with the default fonts can be a challenge on Linux/Unix. I, for one, can't work properly without the Windows fonts comfort Smile

Having the windows fonts working on Unix systems is fairly easy, but on Red Hat-based operating systems such as CentOS or Fedora, can be a real nightmare. The most critical aspect of having the Microsoft fonts to display properly on CentOS in compiling freetype with bytecode interpreter enabled. Let's go through this procedure.

  • OpenMake Software turns its ARA solution into open-source offering
    OpenMake Software wants to improve how developers use the Continuous Delivery pipeline with its recently open-sourced Application Release Automation (ARA) solution, Release Engineer, which is based on version 7.7 of the ARA solution and offered under the FreeBSD license.
  • Open source needs social freedoms for business to thrive
    When open source was first introduced in 1991 with Linux, it was considered a novelty in the industry, a new toy for developers to play with. Today, it’s a fundamental driver of technology innovation across all software companies, according to Dirk Hohndel, VP and chief open source officer at VMware Inc. “Open source is more than software development methodology; open source is how a group of people interact and how you create fantastic technology,” said Hohndel.

  • Doom-inspired roguelike goes open-source in a bid to outrun Zenimax lawyers
    Last week news broke that Zenimax is threatening legal action against the developer of DoomRL, a free Doom-inspired roguelike. Now, DoomRL's creator is open-sourcing it in an attempt to put it beyond the reach of Zenimax's legal team. Many devs will probably appreciate the symbolic resonance of this move, given that id Software open-sourced the original Doom code almost twenty years ago.
  • 6 organizational growing pains you can avoid
    Everything has a season, and as organizations age—communities, charities, companies, churches and more—they face similar diseases of time. These are emergent patterns of failure that arise not from mistakes but from the consequences of earlier success. In open source, we are seeing the same patterns emerge; this should not be a surprise. Some of them are unavoidable. Understanding them helps leaders reduce the risk that will arise and helps identify them when they do. This is by no means a comprehensive list, but we have encountered all of these modes of systemic failure, some of them often.

  • LibreOffice Goes Online
    Well, Meeks and company have done it. What was at first a rather limited demonstration of LibreOffice running in a browser window is now available as a Docker image for everyone to try out. I haven’t yet, because I’m under the weather with yet another winter cold, but that shouldn’t delay you.

  • AsteroidOS is an Open Source OS for Smartwatches
    Florent Revest is a French computer science student who has been working on an open source operating system for smartwatches for the last two years. Yesterday, he officially launched version 1 of the alpha for AsteroidOS. The goal for the platform was to create something that gave smartwatch owners more control over their privacy, as well as the hardware they purchased. Florent feels that the current proprietary platforms do not guarantee this, and this was the basis for AsteroidOS. He wanted his open source smartwatch operating system to provide freedom with free software, more privacy than other wearable platforms offer, interoperability so it could communicate with other devices, modularity that enabled the user to tweak and change the OS as they see fit, the ability to port the software to as many devices as possible, and gathering a community who is passionate about the platform.
  • AsteroidOS Brings Open Source Functionality To Smartwatches
    Smartwatches may not have taken off like companies were hoping, but they have come quite far in terms of what they can offer and what sorts of features are available for the many different models of smartwatches that are out there. Even with the updated functionality of options like Samsung’s Gear S lineup and Android Wear platforms, though, smartwatches can still feel a little bit limiting, and part of this undoubtedly includes the reason that the operating systems aren’t as open as platforms like Android. That is now changing thanks to a platform called AsteroidOS which is an open source operating system for smartwatches.
