As stated in Wikipedia :

D-Bus (Desktop Bus) is a simple inter-process communication (IPC) system for software applications to communicate with one another.

This post provides a simple code snippet in Perl to help you getting started with D-Bus programming.

If you access the internet through a proxy, you need to set up Amarok to use it to enjoy some of its amazing features such as automatic downloading of CD covers or fetching of the lyrics of the song you’re listenning to. Amarok is really a great media player. if you don’t know it you should definitely give it a try !

Setting up proxy parameters for Amarok 1.4 could be a little confusing if you don’t use the full KDE environment. In this post, I’ll explain how to manually edit KDE configuration files to fix proxy settings.

Merry Christmas to all of you 🙂

This post is a step by step explanation about how to get an OpenSolaris 2008.11 run as a Xen DomU on a Linux Dom0.
To follow this, you’ll need a Linux machine ready for Xen (I run Xen 3.3.0), with vncviewer installed.

This post doesn’t explain the basics of Xen, so you might want to start by learning Xen if you don’t already know a bit of it.

If you need to identify broken symlinks, you can do the following :
find -L . -type l

The -L options instructs find to follow symlinks when possible. Hence no “working symlink” will ever get returned as the targets won’t match -type l (meaning “file is a symlink”).

On the other hand, find will not be able to follow broken symlinks, so the information will be taken from the symlink itself and not from the non-existent or otherwise unreachable target. The -type l will then be a match and the broken symlink filename will be returned.

In this post I’ll cover the basics one needs to know to install, upgrade and remove packages on a Gentoo linux system.

I’ve recently switched to the Gentoo Linux distribution (mostly to experiment with this Linux distro) and I don’t regret it so far. This post is about my first impressions about Gentoo.

I’m trying to install xen on Ubuntu 8.04.1 and here is what I get :

spaghetti% sudo apt-get install ubuntu-xen-server
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ubuntu-xen-server: Depends: python-xen-3.2 but it is not going to be installed
Depends: xen-utils-3.2 but it is not going to be installed
E: Broken packages
spaghetti%

I’ve tried to follow the package dependencies but without success. As for now I’m growing tired of Ubuntu and I’m considering moving away to a more robust distribution … I’d be glad to hear your point of view about that too.

If you have multiple linux kernels with differents options in the command line in your bootloader (grub, lilo or other) and you wonder which one was used to boot, you can find out by looking in /proc/cmdline. Ex :
[root@picolo:~]# cat /proc/cmdline<br /> ro root=LABEL=/<br /> [root@picolo:~]#

I barely knew the guy but the news that he passed away is all around the blogoshpere. If you have 76 minutes to spare, have a look at his Last Lecture at the Carnegie Mellon University, it’s really worth it (I won’t comment on it since it is already widely commented everywhere else). Man, I wish I had this kind of teacher; he seemed to have been the kind of life changing one !
