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.
    • -
  • -
    * show my level of expertise in the language -

Operating Systems

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.

    ANQ

    -

    Description

    - anq -

    ANQ -is a testing environment for distributed algorithms.

    Version Antquarium Prototype

    -

    Antquarium is the predecessor of ANQ. It was an extended course assignment and serves as a prototype for ANQ.

    -
