My PhD research-topic was comparative code understanding. Since I started with the idea of applying case-based reasoning to code understanding and code generation, I also created web-pages for these topics.
I can program in many different languages. I am particularly fluent in Java, C/C++, BASIC and SML. I also have some competence in Perl, LISP, Prolog, Pascal and Z80 machine code, and have dabbled in Haskell, Forth, ABC, Logo, 68000 machine code and MU0 machine code. I have only bothered to create web pages for a couple of these languages, though.
