Programming
On my free time I play around with various programming languages and technologies.
C and C++
I was introduced to C and C++ around 1994. Since then C and C++ have been my most used programming languages. Today I code C++ for living.
In the past I have made some public GNOME (1.x) applications.
Java and J2EE
So far I have done three J2EE projects. If I am lucky clients will put two of those online some day.
I have also played with Eclipse and GEF.
Python, Ruby, Perl
I use Python, Ruby and Perl for simple scripting or small web applications (CGI).
I know the existence of Ruby on Rails but I haven't had time to learn it yet.
Ada
Ada is a relatively new addition to my programming toolbelt. More info can be found from a separate page.
Tools
The editor of my choice is Vi. For small things I use nvi and for bigger projects ViM.
For version control I use either CVS (university projects), Subversion (at work), or Monotone (personal projects).
