A text-only version of the presentation I gave at Redevelop.io.
The original version can be seen on Speaker Deck.
Note: there are actually 11 things
Requires Ruby (1.9.3-p327), Bundler and Sass.
Run bundle to get the gems and open index.html in a browser.
A static version of the presentation can be seen at http://tombye.github.io/redevelop-2014-presentation/.
