Chaos Communication Congress

December 26, 2011 - 11:33 pm

Shame on me – I haven’t written a single post in my english blog for almost one year.

Well, there were not so much noticeable things this year. OFS is proceeding good. Not because of me but thanks to Peter who has improved support for NFS and cleaned up the code a bit.

Nevertheless, one of this years real highlights is just about to take place. I checked in to a Hostel in Berlin today to visit the Chaos Communication Congress starting tomorrow. I’m very keen on what’s ahead, since this is the first time I visit this congress – and the first time I visit Berlin.

Merry Christmas!

An exciting year is coming to its end.

I started being part of an ISO committee on behalf of AUDI and did a presentation about OFS at Linux Kongress, one of the most popular Linux conferences. These are just two of the opportunities I had this year. Another highlight again was the WillowCreek Kongress in Karlsruhe, where I was part of the technical production team. And I already got a invitation to join them again in 2011 and I accepted. I’m also very happy that I had the possibility to play music with many different people and varios bands.

With the end of this year my time as guitarist at the YouthEvent band draws to a close. YouthEvent will be discontinued next year and I decided not to change to one of the worship teams at JesusCentrum. It was a hard decision, but I’m sure something new is waiting for me.

It was a great year altogether and I’m happy to see what the next year is going to carry.
I want to wish all readers of by blog a blessed Christmas and a successful year 2011.

What would it be if Jesus were born these days?
Have a nice holiday with this modern story of the nativity. ;-)

Standardizing ISO 22900-2

September 20, 2010 - 11:36 pm

For a few weeks now I am participating in a working group of the ISO (International Organization for Standardization). This group specifies an extension to the existing standard document ISO 22900 part 2.

At EB (Elektrobit) I am primarily engaged in vehicle diagnostics. Particularly in network protocols and vehicle bus systems such as CAN which are used for communication between a PC and the car. To abstract vehicle architecture and diagnostic protocols from the diagnostic application, a set of software components called the MCD-System has been created. The ISO 22900-2 document is about a software component called D-PDU-API which will be used as the bottom most layer of this architecture. As the name implies this is an API for constructing PDUs of Diagnostic protocols. Beside providing implementation of all relevant protocols it serves as an abstraction to the hardware interfaces.

As part of an international standard for vehicle diagnostics, called WWH-OBD (World Wide Harmonized On-Board-Diagnostics), Ethernet is being adopted as diagnostic interface in cars replacing the CAN bus. For this purpose the Diagnostics over Internet Protocol (DoIP) is being specified as ISO 13400. My college who is engaged in the respective ISO working group wrote an article about this standard on the EB tresos blog.

The purpose of the working group I am associated with is to bring this new DoIP standard into the D-PDU-API standard.

Working in a standardization committee is a new but great experience for me. We made good progress in the last weeks and it’s interesting to share knowledge and discuss highly technical details together with other experts in the area of vehicle diagnostics to prepare a document which finally will become an international standard.

OFS proposal for Linux-Kongress accepted

July 1, 2010 - 5:16 pm

Linux-Kongress 2010I’m very happy to inform you, that I will speak at this year’s Linux-Kongress.

Some weeks ago I submitted an abstract for a talk about OFS. This week an e-mail from the chair of the program committee arrived, telling me that the proposal had been accepted.

Together with Prof. Trommler and Samuel Walz, student from the last OFS project group, I will prepare the paper as well as the presentation.

The Linux-Kongress will take place at the Georg-Simon-Ohm University – the home of OFS. You will find more information such as programm and abstracts on their website

Our talk is scheduled for 1:30 pm on the second day of talks and here is the link to the abstract.

Now there’s much work ahead, but I’m looking forward to this event.

Typo3 – my recommendation

June 4, 2010 - 3:46 pm

Typo3 Backend

Typo3 Backend

A few weeks ago I finished my first website based on the Typo3 CMS. The page of CJB (Christian Youth-alliance in Bavaria), which I took over webmaster position several years ago needed a complete redesign and in conjunction with this I decided to apply a content management system.

I’ve taken some time zu evaluate some others like Joomla!, CMS Made Simple and Redaxo but eventually got stuck with Typo3. I must admit it’s not that fast to learn but once you got the overall concept (and this is enough) you have a very powerfull system.

The software design of Typo3 is one of the clearest I’ve ever seen. Everything seems monolithic to me and it’s extremely easy to make it doing what you want. read on »

OFS linux magazine articles online

December 22, 2009 - 1:08 am


Article in english Linux Magazine

As you probably know we wrote an article about OFS for the german Linux Magazin and the english Linux Pro Magazine one year ago.

Both, the german and the english article are now available online.


I really recommend reading it if you did not had the possibility to get the magazine.

We wrote about the concepts of OFS and our plans. We went a big step into the right direction, but there is still much work. For example OFS is much more stable today, but we still lack a decent GUI.

Take a look at the articles and share our ideas.

DLNA – Easy home entertainment

December 12, 2009 - 10:32 pm

My father recently bought a new TV from sony which, beside other cool features, has support for DLNA.

DLNA (Digital Living Network Alliance) is a standard for networking entertainment devices such as TVs. One simple use-case is to have a server containing media files such as pictures, videos or movies. On the other hand you have your TV, Playstation or simply DLNA-able PC client as a viewer. The Client enables you to browse your files and demand the server to stream selected files.

Being a tech-interested person I tried to turn my linux server to a DLNA server. I discovered a very powerful daemon called minidlna. This was probably the easiest server I ever set up. Just copied the configuration file template to /etc, adjusted the directories my mediafiles are located and listed the network devices for communication.

Everything worked out of the box. After starting the server it scanned my configured directories for media files and announced itself via UPnP. I instantly was able to browse my media files from the TV, watch pictures and videos and listen to music.


A very nice toy.
I have seen few software working such smooth, easy to set up and use.
You don’t need to pull out your notebook, boot it up, connect to the TV, log in, operate the PC, … – Just sit back into your couch take the remote control and browse through your files.

If you regularly show pictures of your last holyday to friends and relatives or watch movies located on your harddisc I recommend having a look at the DLNA concept.
