Parrot is a virtual machine designed to efficiently compile and execute bytecode for dynamic languages.
Parrot is not about parrots, though we are rather fond of them for obvious reasons.
Guru at Guru Labs for 1.5 years. I teach, work on courseware, and assorted Perl programming. In my spare time I work on Parrot and recently a roguelike. I've been working on Parrot for about a year, in which time I've written a LOLCODE and Ruby compiler and done a lot of work on Exceptions and some work implementing features in Perl 6.
I'd like to talk about Parrot and/or Perl 6! That's about as specific as I get. If nobody has any more-specific requests, I'd like to run through implementing a simple language and the parts of a Parrot compiler. Maybe scheme? I haven't decided yet.
