ForzaDroid, Forza Motorsport 3 suspension calculator for Android

When Turn 10 offered Forza Motorsport 2, I bought an XBOX360 just to play this game. And I didn’t regret it. During more than two years I played approximately 3.000 games online, most of them in the public lobby system that Forza Motorsport had. I’m not a good racer, but I improved over time. I primarily try to have fun while racing clean.

During the first month of Forza Motorsport 2 online gaming, one of my new online friends I met in the public lobbies tuned one of my cars for me. Wow, what a difference that was compared to the not tuned car. It handled much better and was faster, too. Armed with the knowledge that tuned cars can have better handling and can be faster, I tried tuning some of my other cars myself. Hmm, was much more difficult than I had thought. Most of it was trial and error, and I got tired fast.

instantOLAP: The ROWNUM() function and grouping

InstantOLAP is a lightweight reporting and OLAP system. It’s made for OLAP reports. But if we have a non-aggregating query, we can still list all the rows by using the ROWNUM() function, which helps iterating over the result set. But we’re not able to use a dimension for grouping the rows of the result set.

I’ll give an example: imagine we have rows describing some customers. Each customer is in exactly one customer category. What we now want to have is a list of all these customers, but grouped by customer category. And because we have a dimension for the customer category, we want a separate table for each category. The naive solution seems to put the customer category dimension as an iteration into the outer block of the pivot table. But this will not work because ROWNUM() – an thereby the LINE_DIMENSION – is the only dimension used for iteration.

The Google Chrome phenomenon

I have heard of Google Chrome for the first time on September 1st. A comic strip about Chrome was leaked on the Internet. At that time, there was no software download available. Rumors soon followed about the early availability of a beta version and a Google press conference the next day. This press conference actually took place and the software was then available for download in a beta version.

In the tech-oriented area of the internet, Google Chrome caused more heavy waves than any comparable event before. Reports and discussions surfaced everywhere. According to one source, Google Chrome already had a market share of over 1% after only a few hours – probably caused by curiosity like mine.

Enough Talend for the job?

I’m part of a team that builds a data warehouse for our client, an international recognized car and motorcycle manufacturer. Right now, the data comes from various sources, most of it is provided in CSV files. As a first step, these files are loaded into a staging area. It has been decided to accomplish this task with the help of an ETL tool. The tool that has been selected is Talend Open Studio (TOS).

Wicket first contact

While working on an AJAX web application a couple of weeks ago, a co-worker asked me what I know about Wicket. Not much at that time. I knew it was some kind of component based web framework, but only in the sense like everybody knows that Porsche is a German car brand.

During the recent holidays I spent the entire time away from work and with my family. As most of the time when I’m away from work I made a list of things to look at. Wicket was not on that list. I seldom make it at least half way thru that list anyway. It was the same this time. But then I saw this article on TheServerSide about the release of Wicket 1.3. The big amount of comments caught my interest. Suddenly, Wicket was on that list.
