I've got a brand new talk in the works, which I will be delivering at both the French Perl Workshiop (Lyon, 16th-17th November) and the Israeli Perl Workshiop (Tel Aviv, 31st December). I will be talking on the topic of parallelism - why we need to do it, how (not) to screw it up, what Perl 6 will bring to the table and some of the latest research for future ideas, including lock-free data structures. I hope to announce more European dates for the talk over the coming months, subject to it being accepted at more conferences.
