I went to hear Dan Sugalski give a presentation on Parrot internals to the Phoenix Perl Mongers Group. Dan intended to record the audio and make an MP3 available, but it didn't quite work out. I took some notes, but they are a bit sparse, since I had anticipated the existence of the audio recording. :( The talk was very good, and I put up a page based on my notes and recollections, at http://www.rubyxml.com/parrot/parrot_notes.html Slides from Dan's talk should be available on one of the Perl/Parrot sites as well, soon. Thanks to Dan for the presentation. It's part of a fund raising effort on behalf of the Perl Foundation, and even if you don't use (or even like) Perl, you might consider a contribution. Parrot offers some attractive options for Ruby. http://www.perl-foundation.org/index.cgi?page=donate James
