it's the know why, not the know how

This article is still a draft version. Don't take it to serious. I'll update asap.

You can have one repository with multiple remote repositories that you can push and fetch/pull from.
In the following few lines I will explain a setup that uses 3 remote repositories: A, B and C
This could be repositories at an other physical location such as customers or an off-site premises of your company.

Repository A is the repository in your local company, repository B is placed in an other city were a second team works on the same project and repository C is placed at your customer. You have the job of integrating branches and push them to your customer.

Nachdem Ich nun meinen letzten Rechner gnadenlos platt gemacht habe und den letzten Microsoft Vertreter von meiner Platte verbannt habe glänzt nun eine frische saubere Ubuntu 10.04 Installation auf meinem Desktop.
Der einzige Grund bisher Windows als 2. System zu haben war die ruckelfreie Wiedergabe von mkv files. Meist gestückt mit 1080p Videos. Hier hat mir PowerDvD in der neusten Version dank Hardwareunterstützung stets treue Dienste geleistet.

Here's an other little post, trying to spread knowledge!
Today we want to backup stuff like our personal pictures from our local disk, through the network onto an other computer.
For this to function the remote computer has to have an ssh-server installed. Our local computer needs to haven an ssh-client available and rsync installed.

So, here I am, after reconfiguring the webserver,...
I finally decided to test out Drupal's blog module. Since I'm rather interested in spreading knowledge than telling you some boring live stories I'll try to post some simple how tutorials.

Todays topic will be setting up multiple Virtual Hosts on an Apache 2.2 server. Assuming that you a reading this because you want to set up a virtual host, I think you've mastered setting up the apache web server yourself already. If not, and you are running an debian based operating system type "apt-get install apache2" with root privileges into your command line =).

On an apache you can run two types of virtual hosts. They are either name based, or ip based.
- Name based virtual hosts are several hosts (websites) all running on the same IP address.
- IP based virtual hosts are several hosts (websites) all running on unique IP addresses.

It is possible to run Virtual Box on a computer without a graphical frontend, for example - on servers. In this little tutorial we are gonna setup two virtual machines using the shell. These machines will both be connected through a virtual network and use one shared folder. Both systems will be running in virtual boxes "headless" mode. This means there is no output! However, we will add an virtual remote desktop server that you can connect to with a remote desktop.

This tutorial is written for Virtual Box 3.1.2 on a Ubuntu linux host system.
Virtual Box is a powerful virtual machine software and can be downloaded for free right here: http://www.virtualbox.org/wiki/Downloads

Here is a wonderful ASCII Picture of the setup. I hope it helps you understand what I'm trying to set up :-)

While experimenting with Linux Raw Sockets I came to the need of calculating checksums myself. Of course I know that we can just enter 0 into the checksum field and the kernel will do the rest for me! But whats the sense in digging around inside the kernel, knowing every detail about raw sockets, but not being able to do such a simple task alone?
