It's also worth mentioning that Girl Friday (along with a slew of other worker/queueing gems) were also written by Mike Perham. Sidekiq is his latest and greatest attempt at efficient message queueing in Ruby.
Great screencast as always! Just wanted to let you know that I released my first RubyGem a few months ago (inspired by all the recent pub/sub libraries). It's called Mad Chatter. It's a host-your-pwn Ruby chat server using EventMachine and em-websocket. I'd love to get some feedback/advice/contributors. Maybe I'll switch to use private_pub. ;-)
