Silverlight VideoPlayer for RailsCasts
Jun 1st
I am and will be a Microsoft Developer. While working for convenience with other tools, I love strong type languages. I don’t want to ship products because I saved once and hit “s” one more time, so my product will be shipped with that small, human and yet unpardonable error in code.
How many times did you loose your time and effort with PHP in order to find a small mistake like this?
In my pursue on Microsoft tools path I started enjoying the Silverlight technology. Who might not know, Silverlight is a competitor to Flash. By now, on its 4th More >
Railscasts Silverlight video player
May 31st
This is my second shot to create a better player for Railcasts. As you can see, it goes better and better. Who knows what might be next?
If you want to know more about the process through which this player was designed you can read also:- How and why I choose the Silverlight platform

How to add ui-icons to JQuery tabs
May 25th
While working in UniBonn, I have a lot of contact with Ruby on Rails and JQuery; I actually started loving its interactivity and stability. But lately I encountered a small situation with the tabs object that they offer.
This is their default view, with Redmond theme applied. Nice and clean, you might say. But what’s missing? These tabs don’t support images. So you’ll not be able to show an image to specify, let’s say, that this tab has some updated information or a warning that something important is inside that tab.
I wanted to have some kind of control on specifying how the More >

Position: Assistant Researcher ( WHK or Wissenschaftliche Hilfskraft )
Starting 1. March 2010 I work in Informatik 3 Department of Rheinische Friedrich-Wilhelms-Universität in Bonn.
My master is a joint effort between Uni Bonn and RWTH Aachen. During my master, I had the pleasure to be part in the Agile Lab, where I encountered two PHD students, Pascal Bihler and Mark von Zeschau. They are true developers, result driven people and fair judges of our activity. During this lab, which was intensive, we had 3 weeks as developers in an almost real company environment. From 9 to 18, if you know what I mean.

GPS vs aGPS vs WiFi vs GSM localization
Aug 26th
Each method presented has its strengths and weaknesses. None of these is the perfect positioning system, yet they all can collaborate in order to give the estimated position of a user.
GPS, the veteran of the group, has a plethora of satellites at its disposal, offering almost anywhere in the world a precision in meters. The devices which implement this technology are small enough to be inserted even in phones, smart enough to do their job or even more by tracking many satellites in the same time and eating less power, affording the usage of this service for hours in a More >
GPS – Global positioning system
Aug 24th
GPS is the oldest one from the frameworks available to the large audience. It isn’t the first positioning system, but it is the one with the most success and longevity. It started as a military project in 1957. Because of the cold war, once the Russians sent to space the first man-made satellite, a team of scientists started monitoring its radio transmissions. The crucial discovery was that, because of the Doppler Effect, the signal transmitted frequency increases as the satellite approached, and lowers as it continued moved away from them. This added to the fact that they knew their exact More >

Agile roots: Toyota Production System
Aug 19th
This methodology and set of principles has the root in the company with the same name. After the Second World War, the Japan and its companies were almost ruined both physical and financial. To recover the economy, they had to rethink all the processes of production in order to maximize their efficiency. This was required because not only that they lack financial resources, but even the loans that they could do as a country came with big price. In Toyota Company, a smart man called Taiichi Ohno, created a new way to build cars, focusing on creating as many quality More >
