Allen Rohner will talk about CircleCI - https://circleci.com/?join=clojure - which is a production Clojure application.
He is happy to cover either of the following topics
* Real-time Web UI in Clojure - how to create an amazingly responsive UI with knockout.js, pusher.com and Clojure ref watchers
* Testing in Clojure and how to design testable code
The main topic will be picked at the meetup, by a show of hands from attendees - and if there's time, he may be able to cover the secondary topic too.
A big thank you to Allen for volunteering to step up at the last minute!
