ROSI - Rotating SICK Laser Scanner

My responsibility was the development of the Window client, including its GUI and 3D visualisation + in OpenGL. The Windows client is responsible for: +

+Problems that the team had to solve were: extending the hardware to get +an absolute reference point for the rotation, solving overheating +problems on the embedded system, providing lossless synchronization +between the server and the clients and efficiently managing the highly +dynamic stream of vertex data.

Does Size Really Matter?

To +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 +my desktop system. I'm open for suggestions, it has to be:

+ big keyboard + +

If you have any recommendations, preferably by own experience, then please let me know.

Back to Basics - A New Dawn

+

water + ME73 made it to version 3. What has changed? Everything. I've stripped away anything that was not essential for the site. + 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 + Styleshout.

+

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

Where Are The Old Tutorials?

+ questionmark +

Despite the elementary nature of my tutorials, they've created a suprisingly steady stream + of traffic for my site. 

Today, +I believe that tutorials can cause more harm than solve problems. +A tutorial will not replace a well done research, a good book and +proper education. It will, however, in many cases promote quick and +often unsafe solutions without a real understanding of the underlying +material.

Programming Languages

+

binary +During my studies and personal work, I've used a variety of programming +languages. Here is an overview in chronologic order with some comments:

+
    +
  • +

    QBasic. *

    +It was the first language that I've learned. I've enjoyed hacking +around in it a little, but never got far with it due to lack of +learning resources.
    • +
  • +

    C++. *****

    +This was actually my second language to learn, which meant a big leap. +My first contact was at the age of 15, though I hadn't used it +extensively until I started studying. In the past years, I've been +developing most of my personal and professional work in C++. It's a beast and should be +only handled with care.
    • +
  • +

    Java. ***

    +My first contact with Java was at the university. It does provide help +by managed memory and a big standard library. +
    • +
  • +

    Haskell. *

    +This language was a love-hate relationship for me. I hated it for being +so difficult to grasp for the first time and loved it for inspiring me +to approach problem solving from a differnt angle, even when working +with non-functional languages.
    • +
  • +

    Prolog. **

    +Nice iterative language especially for the field of artificial +intelligence.
    • +
  • +

    C. *****

    +C is clean and flat. It is still the most successful structured language and will most +probably still be in use for many years to come, even if it's just "under the hood".
    • +
  • +

    Assembler. **

    +Been there, done that.
    • +
  • +

    C#. ***

    +It feels like the more mature language based on a managed +architecture, especially in combination with Visual Studio, developing +in it is a breeze. The .Net framework is mostly a well structured and +complete environment to work in.
    • +
  • +

    Python. ****

    +It's my personal favourite language for many fields. It's best suited +for rapid prototyping, which fits perfectly into my method of working.
    • +
  • +

    Go. *

    +Google has developed an interesting language with the goal of providing a general programming language including a garbage collector and efficient methods for concurrency handling. It's a fun language and shows some interesting concepts including a more dynamic approach on object orientation.
    • +
    * shows my experience level with the language +
+

Operating Systems

+
    +

  • GNU/Linux

    +Ubuntu, openSUSE, Red Hat and CentOS.
    • +

  • Microsoft Windows

    +Windows 95/98/2000/XP/Vista/7.
    • +

  • AmigaOS

    +Been a while...
    • +
+

Environments

+
    +
  • +

    GVim & gedit

    +These are my general purpose editors for quick editing on all platforms +and have become my prefered editors when working in an IDE-free environment.
    • +
  • +

    Visual Studio

    +It's my first choice for C#, C++ and C programming on Windows. It has +proven to be a feature-rich, reliable and customisable IDE with great debugger integration.
    • +
  • +

    Eclipse

    +It's what I prefer when developing in Java and, to some extent, when +working in C++ on Linux. It has a great plugin system and is therefore +extendable to be used with a big variety of languages.
    • +
  • +

    Wing IDE

    +When it's Python-time, this is what I like to use. Great debugger, +overall nice GUI and features. Free version is missing crucial +features, though.
    • +
+

Tools

    +
  • +

    Internet

    +Chrome for browsing, IRSSI for IRC and Skype for communication.

These programs try to predict critical situations and alarm ATC +controllers ahead of time. Examples include Short Term Conflict Alert +(STCA) systems, Minimum Safe Altitude Warning (MSAW) systems, and Area +Proximity Warning (APW) systems. STCA systems predict the flight paths +of different aircraft and issue a warning up to two minutes ahead of a +potential separation violation. MSAW and APW systems predict single +aircraft trajectories and issue a warning if there is a significant +risk that the aircraft comes too close to a terrain feature, +obstacle, or prohibited region. + +While the basic trajectory prediction is always based on the same +principles, the generation of warning messages is highly dependent on +local conditions. The quality of the sensor coverage dictates aircraft +separation rules. Local geography may require trajectories that would +normally be avoided. Availability of flight plan information can help +to recognize potentially dangerous situations as already anticipated +and under control. As an example, if a flight plan contains a cleared +altitude of 300 flight levels, the aircraft is expected to level off +its ascent there, and hence will not conflict with an aircraft at an +altitude of 320 flight levels, even if a naive projection based on the +current rate of ascent does indicate a potential conflict. + +Currently, Safety Net systems use standard requirement engineering to +identify the necessary conditions for each particular +deployment. These requirements are then translated manually into +program code. However, this process is tedious and error-prone, and +the resulting code can be rather complex and hard to maintain. Each +modification requires extensive re-validation of the software. + +The aim of this thesis is the development and implementation of a +language that can express the necessary conflict for an ATC Safety Net +in symbolic, human-readable form. Depending on the outcome of an +initial feasibility study, the language should be either interpreted +by the Safety Net System, or automatically compiled into C++ code. + +For this purpose, first the necessary attributes and relations have to +to be identified. Then a proper rule semantics (prioritised, weighted, +non-monotonic/exception-based...) has to be determined, and finally an +initial prototype language needs to be designed and implemented. + +---- +Comsoft is a medium-sized, privately owned company located in +Karlsruhe/Durlach.

Where Are The Old Tutorials?

+ questionmark +

Despite the elementary nature of my tutorials, they've created a suprisingly steady stream + of traffic for my site. 

Today, +I believe that tutorials can cause more harm than solve problems. +A tutorial will not replace a well done research, a good book and +proper education. It will, however, in many cases promote quick and +often unsafe solutions without a real understanding of the underlying +material.
