1.4 + <h2><a name="2">ROSI - Rotating SICK Laser Scanner</a></h2>
1.5 + <p>
1.6 + Take 8 people, one 3D-laser-scanner, an embedded Linux system and
1.7 + the goal of developing a Linux client, a Windows client and the embedded
1.8 + Linux server application. Get a lot of challenging problems, even more work
1.9 + but a rewarding accomplishment of succeeding at something others have failed before.
1.10 + </p>
1.11 + <p><img src="images/team1.png" alt="ROSI team" height="280" width="400" /></p>
1.12 + <p>My responsibility was the development of the Window client, including its GUI and 3D visualisation
1.13 + in OpenGL. The Windows client is responsible for:
1.14 + </p>
1.15 + <ul>
1.16 + <li>Visualising the 3D vertex data stream from the server</li>
1.17 + <li>Giving the user ways to navigate in the 3D space via mouse and GUI buttons</li>
1.18 + <li>Setting the colour-mapping of depth and remission values of the scanner data</li>
1.19 + <li>Loading and Saving LAD-files and LAD-file sequences (possible directly from the stream)</li>
1.20 + <li>Setting scanner configuration remotely</li>
1.21 + </ul>

1.25 + </p>
1.26 + <p>
1.27 +Problems that the team had to solve were: extending the hardware to get
1.28 +an absolute reference point for the rotation, solving overheating
1.29 +problems on the embedded system, providing lossless synchronization
1.30 +between the server and the clients and efficiently managing the highly
1.31 +dynamic stream of vertex data. </p>

1.39 + <p>To
1.40 +me it does! Working alot at the university, I've gotten used to the
1.41 +keyboard on my Thinkpad so much, that I'm looking for a replacement for
1.42 +my desktop system. I'm open for suggestions, it has to be:</p>
1.43 + <img src="images/bigkeyboard.png" alt="big keyboard" class="float-right" height="100" width="167" />
1.44 + <ul>
1.45 + <li>Notebook size, full sized keys</li>
1.46 + <li>No numpad</li>
1.47 + <li>Quiet but well defined key stroke</li>
1.48 + <li>Wired</li>
1.49 + </ul>
1.50 + <p>If you have any recommendations, preferably by own experience, then please let me know.</p>

1.58 + <strong>ME73</strong> made it to version 3. What has changed? Everything. I've stripped away anything that was not essential for the site.
1.59 + Now it's composed of strict XHTML, CSS and a little Javascript.
1.60 + Since I don't enjoy working on websites much, I've decided to base my site on an existing template from
1.61 + <a href="http://www.styleshout.com/">Styleshout</a>.</p>
1.62 + <p>You
1.63 +will have noticed, that I've switched to a dark background, this has
1.64 +several reasons. Since I'm spending a great portion of my time in front
1.65 +of a computer screen, I'm looking for ways to improve my working
1.66 +envirnoment to keep the experience as pleasing and repercussions as low
1.67 +as possible. I've found that working on dark backgrounds puts less
1.68 +strain on the eyes, especially when sitting in a dark room. Another
1.69 +reason is my idea of creating a more personal ambience for the site
1.70 +with my choice of colours.</p>
