About

Professional Perl programmer and person with a strong interest in Computer Science, Mathematics, popular culture and social justice. No Turing complete language is truly foreign to me but I have a tendency to prefer P* languages (such as Perl, Python and Javascript) and functional languages like Haskell and Scheme.
