Chatting during the workshop
We've set up an IRC channel (chat room) on Freenode where people can discuss the class and post questions and resources.
If you don't know how to use IRC, you can just click on this link to a web chat interface. It will take you to a page where you can sign in to the chatroom.
Installing an IRC client: Optional!
IRC is a real-time chat protocol that open source projects often use to talk about the project and as a medium for users and developers to help each other. IRC clients have a nicer user interface than the webchat interface, so you might want to try them out. This is optional. Here are some pages that explain how to install clients.
