I just wanted to capture how sleek and responsive the UI is:
The secret sauce: the entire console is a single-page client-side JavaScript app, using Sammy.js, so all the interactions and rendering are happening on the client side. It helps that Safari is damn fast.
The client-side code gets data from the back-end, itself a lightweight Sinatra app. All the responses are JSON, much less data to generate and transmit, compared to say HTML partials or XML nonsense.
Authentication is done using OAuth 2.0, more specifically the HTTP Authorization header, added to all jQuery requests using Sammy.OAuth2. No cookies harmed in the making of this video.
Using MongoDB to store and fetch the data just adds to the speediness of the queries.
Charts rendered by Protovis, which is also quite the speed daemon.
