Take 8 people, one 3D-laser-scanner, an embedded Linux system and
|

sawine@0
|

the goal of developing a Linux client, a Windows client and the embedded
|
|
sawine@0
|

Linux server application. Get a lot of challenging problems, even more work
|
|
sawine@0
|
6 |
but a rewarding accomplishment of succeeding at something others have failed before.

Problems that the team had to solve were: extending the hardware to get
|
|
sawine@0
|
25 |
an absolute reference point for the rotation, solving overheating
|
|
sawine@0
|
26 |
problems on the embedded system, providing lossless synchronization
|
|
sawine@0
|
27 |
between the server and the clients and efficiently managing the highly
|
|
sawine@0
|
28 |
dynamic stream of vertex data. </p>

me it does! Working alot at the university, I've gotten used to the

keyboard on my Thinkpad so much, that I'm looking for a replacement for

<strong>ME73</strong> made it to version 3. What has changed? Everything. I've stripped away anything that was not essential for the site.
|
|
sawine@0
|
56 |
Now it's composed of strict XHTML, CSS and a little Javascript.
|

Since I don't enjoy working on websites much, I've decided to base my site on an existing template from

<p>You
|
|
sawine@0
|
60 |
will have noticed, that I've switched to a dark background, this has
|
|
sawine@0
|
61 |
several reasons. Since I'm spending a great portion of my time in front
|
|
sawine@0
|
62 |
of a computer screen, I'm looking for ways to improve my working
|
|
sawine@0
|
63 |
envirnoment to keep the experience as pleasing and repercussions as low
|
|
sawine@0
|
64 |
as possible. I've found that working on dark backgrounds puts less
|
|
sawine@0
|
65 |
strain on the eyes, especially when sitting in a dark room. Another
|
|
sawine@0
|
66 |
reason is my idea of creating a more personal ambience for the site
|
|
sawine@0
|
67 |
with my choice of colours.</p>
