small and simple-to-use vocabulary training app
First I implemented this piece of software when I was back in school and I was not really good in learning the French language. I liked coding much more, so I decided to build a simple piece of software in Visual Basic. Of course, it was more a trial and error kind of thing than real software development.
Later on, when I lost the original sources, I decided to re-implement my tool in Java to train my programming skills and try different things with version control systems and so on. Maybe I'll also use it to learn another language someday (or to re-learn French).
