I work with C++, C#, Perl, PHP, HTML (with a lot of CSS), and a little bit of ASP.NET. I have been programming for 7 years.
I also enjoy translating Latin, and especially reading authors whose primary language was Latin, including Virgil (or Vergil for the Latinate spelling), Julius Caesar, Catullus, Cicero, and some others (like Martial). I enjoy classical music, most especially Mozart and Bach.
