I'm amused at the traction this little gist is getting on Google! I would be remiss not to point out that six+ years later I'm still helping thousands of companies on a daily basis with their search index management, by providing managed Solr as a service over at Websolr, and hosted Elasticsearch at Bonsai. Check us out if you'd like an expert helping hand at Solr and Elasticsearch hosting, ops and support!

In an earlier video we took a look at Rack to build incredibly lightweight web applications with Ruby. Rack's toolkit allowed us to quickly throw to get a working application, but we did have to put a little effort into it once we wanted to build something a little more complex.

Sometimes you want a fast and simple framework for building a simple web application. Perhaps you only need to respond to a handful of routes, or you want the response time for a small part of a bigger application to be lighting fast. The Sinatra framework is made for just these moments.

Today let's take a quick look at this framework and see how quickly we can build lightweight web applications.

To get started we first need to install the Sinatra gem:

gem install sinatra

	sub, sup {
	/* Specified in % so that the sup/sup is the
	right size relative to the surrounding text */
	font-size: 75%;

	/* Zero out the line-height so that it doesn't
	interfere with the positioning that follows */
	line-height: 0;

	/* Where the magic happens: makes all browsers position

	: By writing unit tests and running them after each new change to an application, we can spot new bugs
