Saturday, at 1:30 PM, I'll be giving a talk on using the asynchronous toolkit I've written for GObject. Those that enjoy twisted's deferreds will feel right at home. If you don't understand GLib or GObject, I'll be giving a short overview on those as well.
Even if you do not enjoy hacking C, there will plenty for you. Earlier this week I created some demos for asynchronous methods crossing the language barrier which I think people will enjoy.
