Building A Calculating Machine Using LEGO® Pieces

Look at this marvellous piece of art! It is a difference engine built from a *whole lot* of LEGO pieces. Way cool thing. Must be fun to listen to it. :-) Reminds me of the Artihmeum, the fascinating local museum for historical calculators here in Bonn, Germany. They even have a still working instance of the Enigma cipher machine.

Feed normalizer allows ATOM syndication in Joomla

My website is now based on the Joomla content management system. I tried to syndicate a few of my friends’ blogs (Gernot Starke and Markus Voelter) in the “Blogs” menu of the website and found out that Joomla has problems with ATOM feeds – it simply cannot display them!
On the Net, I found Feed Normalizer, a nice and handy tool to convert ATOM and other feeds to RSS 2.0 which works perfectly with Joomla. It is a CGI script, it is written in Python and: it is open source! After installing Python, Feed Normalizer and Universal Feed Parser on my webserver, I can syndicate ATOM feeds, now. It still has some problems with German umlauts but that’s OK.

Architecting AndroMDA 4

At the moment, I am designing and documenting the architecture for the new release of AndroMDA. I’ll publish it as several sections of Joomla pages, each divided into several categories. As a guideline, I use the arc42 template for software architecture documentation, created by Gernot Starke and Peter Hruschka.

New website using content management

It was time for a relaunch of my website. I used Joomla, an open source content management system which is easy to use and performs well.
