How I built my first Hackintosh?

How I built my first Hackintosh?

It started once on Lifehacker, with reading something around self-build PCs, called Hackintosh, which are running the operating system of Apple. Now, when I wanted to upgrade my old box, I went back, read it again, and decided to my build a hackintosh. So I'm going to install the Yosemite version of Mac OS X on a self-build hardware, as described on

Jekyll is one of the most popular static site generation tool. It's getting into the mainstream, Github uses it extensively at Github Pages. It makes blogging really simple, but unfortunately, setting up a self-hosted Jekyll environment is not that easy.

How to use Vagrant?

Vagrant makes development environments easy: creates and configures lightweight, reproducible, and portable development environments. Create a single file for your project to describe the type of machine you want, the software that needs to be installed, and the way you want to access the machine. Store this file with your project code.

Setup of Ganeti cluster on root servers of Hetzner

I'll setup a 3 node Ganeti cluster on Hetzners root servers, to run static and Drupal based sites for friends and NGOs. Ganeti is designed to facilitate cluster management of virtual servers (the "instances") using commodity hardware (the "nodes"). It provides fast and simple recovery after physical failures, disk creation management, operating system installation, startup, shutdown, and failover between physical systems.

Network setup of proxmox VE 2.x on hetzner server

In the second part of the series I'm going to setup routed networking on a root server of Hetzner, for KVM based virtualization and with Ubuntu 12.04 LTS guests. These guests will be webservers and database-servers, connected by private LAN with internal bridge NAT-ed to eth0 of the host. Shorewall and Fail2ban will help to get the proper networking in place, next to security. Finally, a Pound load balancer (reverse proxy) with one additional public IP, will be setup, as well.

Setup a root server for Drupal hosting at Hetzner

After several years of web hosting at, I decided to move one step further and setup my own Drupal hosting solution on a Hetzner root server, using KVM virtualization and Aegir. This change has nothing to do with, their web hosting service is still perfect, cost and quality is OK. I just wanted to have something more to play.
