#Intro

Holla is a group chat app. The UI is built in a RIA fashion - i.e. is totally asynchronous and super fast. I've open sourced it for a book I'm writing on building Rich Internet Applications with JavaScript.

A WebKit based browser (Safari/Chrome) is required due to specific CSS optimizations.

I've made some changes to make it more usable. My patch store all coversation in db - not in memory.

• Ruby 1.9.2
• Bundler
• Redis
• Nodejs

Install ruby & bundler

cd /tmp
wget http://nodejs.org/dist/v0.8.8/node-v0.8.8.tar.gz
tar -xf node-v0.8.8.tar.gz
cd node-v0.8.8/
./configure
make
sudo make install

npm install -g juggernaut

bundle install
rake db:seetup
bundle exec foreman start -p 3000

Now go to http://localhost:3000
