Learn and fun

Before writing programs became my profession I spent a lot of time learning programming languages and technologies. Today, despite the fact that I am a professional programmer I am still learning. Before I use a new technology in a commercial project I have to practice it on a small private project. A side effect of such practice are various strange programs, some of which are even interesting.
