I have been using reveal.js to create slideshow from markdown. It’s very nice and powerful. But the setup is a bit complicated. Sometimes i want to have a more simple solution.

Last time we have integrated the RSpec and Autotest in Rails 3.
Rails – Integrate Autotest and RSpec in Linux
But it seems that it takes quite long for RSpec to complete the tests. This is because RSpec reloads the entire Rails environment for each run. Spork Test Server helps you preloading the Rails environment which greatly reduces the time for running the test suite.

I am learning Rails 3 @ Ruby on Rails Tutorial by Michael Hartl. A very nice and detail tutorial with many examples for beginners. Highly recommended.
But i got some problems when i tried to setup the Autotest for the RSpec framework. Autotest is a continuous testing tool which run the test suite automatically based on the files you have changed.
