Software developer best in C++, Java, and Ruby, and Pascal.
I've had a taste of almost everything, however, and I know a little of Python, Perl, SQL.
I also know HTML, XML, CSS, etc.
If I don't have an answer I can get one quick. (Google-fu)
My greatest advice to anyone wanting an answer is learn ALL (advanced) Google syntax. That's "filetype:", the dash filter, "site:", "cache:", and so on. (Spoiler: you can't - it's database query on a scale no mortal can memorize. But add more to your belt.)
