mdpress – Present your markdown file in slideshow

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.

Other than reveal.js, impress.js is a similar tool which allows you to present your ideas in a even more fancy way. I am not going to go into details of impress.js. Instead, i would introduce a tool called Mdpress which generate the .html presentation from markdown.

1. Install the Mdpress.

gem install mdpress

rbenv – Ruby version manager

rbenv is an alternative to rvm for managing your Rubies. You can find some articles comparing the two.

Rails – Integrate Autotest and RSpec in Linux

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. RSpec is a Behavior Driven Development (BDD) framework for Ruby. After a few hours of struggling, i finally made it work.
