Linux / BSD

I have been using Linux on most of my computer since 2007. Before that I have been mostly using Windows. My first PC was MS/DOS + windows 3.11 on a 486 when I was a small.

I am now working as a Linux and Network Sysadmin. Currently I mostly mange Linux and other Firewall as well as basic network services such as DNS, DHCP, Proxy, NTP.

Home Network

On my home network I run a Pfsense Router on an low power PC Engine APU board and a home-built storage server using FreeNAS and the ZFS filesystem.

Check out FreeNas and Pfsense which are two great open source project (which just happen to use BSD).


I am trying to acquire basic electronic knowledge: Proper soldering, understanding circuit and components, using a Oscilloscope (…).

I've also been playing with Arduino.


Beside some (ugly) bash programming, I also have some python programming knowledge.

Special Gadgets

Raspberry Pi: Great little device for hacking.

I also have a Pandora which is a hybrid between a mini Linux computer and a gaming device. http://openpandora.org/

And the “ultimate” geek phone: my Nokia N900. Do you known of any other phone that has a keyboard shortcut for opening a terminal out of the box ?



Using the GPIO on the Raspberry Pi

Try go get the TM1638 working on the Rpi. Waiting for it to arrive (ordered from Dx)

RPi forum: some code to get TM1638 to work on the RPi: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=10787&p=119969

RPi as Squeezebox player

I am now running my RPi as a dedicated Squeezebox player. I am using Squeezeslave and an external USB soundcard. I have a small 2x15w class D board from Sure electronic connected directly (no preamp). Works great for now ;)
