I was born in 1986, and I'm currently a fifth-year computer science student at KTH in Stockholm. My interests include programming, electronics, amateur radio (my callsign is SM0YSR), astronomy, Chinese, mathematics, history, literature, and many other things. Since 1997, my main interest has usually been been programming and computer science.
Note: If you're not interested in computers, you might want to skip the rest.
There are many editors, and many heated debates about their different (dis)advantages. I tend to use Vim for text and source code editing, with this configuration.
In the world of programming languages there are even more intense debates. I started out with QBasic, then Pascal, C and various assembly languages. I've used the last two frequently ever since, and more recently I started using Ruby and Python for prototyping. At some points I've also had to use Fortran, Java, SML, etc.
